The above-described property represents the illustration. Thus, ways of implementation are not limited to these properties. Other properties variants of implementation will be clear from the following description and attached drawings.
Link in the description to "one version of the exercise" or "an implementation option" means a specific property or feature described in connection with the option exercise included, in at least one version of the exercise. Thus, the appearance of the phrase "in one embodiment," or "embodiment" in various places of this description is not necessarily in all cases refer to the same version of the implementation. In addition, various properties, structures or features can be combined in any appropriate method in one or more variants of implementation.
Figure 1 shows the scheme of approximate operating environment 100, which can be used the techniques described here. Wednesday 100 may include different elements. For example, figure 1 shows the environment 100, which includes a platform 101 processing, the device 103 display and interface 105. These elements can be embodied in any combination of hardware and/or software.
Platform 101 processing may include one or more operating systems (OS). For example, figure 1 shows platform 101 processing, in which operating systems work 108A and 108b. However, any number of operating systems can be used. These operating systems can be designed in many computer applications. For example, figure 1 shows platform 101 processing running the application 102a-d. Each of these applications can run in the appropriate one OS 108a-b.
In applications 102a-d graphics used data that lead to one or more displays (such as device 103 display). Examples of applications include various business related applications (such as word processors, spreadsheet application, applications, presentations, email, applications, send messages, etc), business applications, video applications, and/or other applications.
In particular, conveyors a-b graphics processing perform graphics operations in response to the directives received and processed through the graphics API. Approximate operations include granting and out of images (frames) in the device 103 of the display. As described above, conveyors a-B graphics processing can be embodied in any combination of hardware and/or software. Thus, in the variants of implementation conveyors a-B graphics processing can be implemented using one or more modules graphics processing unit (GPU).
Figure 1 shows that the device 103 display includes the physical display 109, media 110 information module 112 management interface 113 user and non-volatile media 114 information.
The physical display 109 provides a visual output to the user. In variants of the implementation of this output is presented in the form of consecutive images or frames. In accordance with this approximate physical displays include a display with light-emitting diodes (LED), liquid crystal displays (LCD), plasma displays and cathode ray tube (CRT). Options for implementation, however, is not limited to these examples.
Each of shots physical display 109, can contain many pixels. Data representing these pixels (for example, color and/or intensity), remain in the frame buffer within media 110 information. Such data can be called "data frame. Thus, by storing the data frame, the frame buffer "controls" physical display 109.
Options exercise device 103 display can provide multiple frame buffers. For example, figure 1 shows a device 103 display, including buffers 111a and 111b of the frame. However, you can use any number of buffers frame. Such frame buffer can be included in the media 110 information. Media 110 information may contain volatile random access memory (RAM) (for example, dynamic RAM). However, you can use other types of media, such as non-volatile storage device.
Options exercise device 103 display receives the data frame of the platform 101 processing. More specifically, conveyors a-b graphics processing (through the interface 105) can provide data to 120 frames per device 103 of the display. After taking the device 103 display saves the frame data in the buffers 111a and/or 111b of the frame. In turn, such stored data frame can be opened by physical display 109 in accordance with the technologies described here.
As described above, the device 103 display includes a module 112 management, which directs the various operations of the device 103 of the display. Such operations include reception, preservation and output data frames received from the platform 101 processing. In accordance with this module 112 control can process data to be transmitted via the interface 105, at time display, with power management, etc. In addition, the module 112 management can control the interactions of the user interface 113 user or through the channel 122 management virtualization software stacks.
Interface 113 user allows the user to interact with the device 103 of the display. Such cooperation may include the execution of user-various operations described here. Such operations include, but are not limited to the choice of frame buffer device 103 display for output, select the output mode buffer one frame or mode output buffer with multiple frames, and submission, and disabling desktop power supply for the device 103 of the display. Interface 113 user can be realised in different ways. For example, the interface 113 user can include various buttons, keys, disk laborately numbers and/or other input devices. In addition, or alternatively, the interface 113 user can include various menus and/or elements of the touch screen provided through physical display 109.
Options exercise device 103 display may include non-volatile media 114 information (for example, storage device type flash). As described in more detail below, the non-volatile media 114 information can ensure that the contents of the buffers 111a-b frame when the device 103 display switches between power States (for example, from a higher state power in a lower power state). Alternatively, options for implementation may provide such properties as a result of implementation of buffers 111a-b frames in the form of non-volatile memory so that they are always available and contain its contents.
Interface 105 connected between the platform 101 processing and device 103 of the display. In particular, the interface 105 allows for platform 101 processing to provide to device 103 display data 120 frame. Interface 105 also allows for platform 101 processing and device 103 display to share with each other information 122 management.
Interface 105 can be implemented in different ways. For example, variants of implementation of the interface 105 may include the type interface "plug and play", such as a universal serial bus (USB) (for example, USB 1.0, USB 2.0, USB 3.0, and so on). However, you can use various other serial and/or parallel interfaces. In addition, the interface 105 can be made with the local cable network (LAN) (such as Ethernet). In addition, the interface 105 can be carried out with the wireless network. Wireless network examples include networks such as wireless LAN IEEE 802.11 (WiFi), IEEE 802.16 WiMAX, and wireless personal area networks (WPAN) (for example, WPAN 60 GHz). However, options for implementation are not limited to these examples.
In variants of implementation buffers street 111A-b frames device 103 display look like "display" for processes and/or operating system platform 101 processing. Thus, in the variants of implementation processes and/or operating systems do not contain data on the physical display 109 device 103 of the display. In addition, options implementation of the user or independent software stack controls how a frame-buffer device 103 display actually looking at the physical display 109. For example, options for implementation provide for a user or software functions "flip" or "flipping" through various buffers frame. Alternatively, or in addition ways to implement allow users or software to display different frame buffers in different independent areas on the physical display 109 so that many frames can be viewed simultaneously.
In variants of implementation, the elements of figure 1 can be implemented as a computer system. For example, the platform 101 processing can be a personal computer and the device 103 display can present it in the appropriate monitor. Options for implementation, however, is not exclusive layouts.
In addition, the elements of figure 1 can include one or more processors (such as the microprocessor). For example, the platform treatment can contain any combination of microprocessors. As an example, the operations described here (such as operations OS 108a-b applications 102a-d and conveyors, graphics processing, can be provided to the Central processor unit (devices) of the CPU and/or module (modules) graphics processing unit (GPU. Such CPU and/or GPU can work in accordance with instructions (for example, software)is stored on the storage media. Such information medium (which can be included in the platform 101 processing) may include memory (volatile or non-volatile), a disk drive, etc. In accordance with this device 103 display may also include one or more processors to provide the properties described here. These processors can execute instructions (for example, software)that are saved on the storage media. Such information medium (which can be enabled in the device 103 display) may include memory (volatile or non-volatile), disk storage media, etc. for More details in respect of such options for implementing provided below.
Operations for different variants of implementation can be further described with reference to the following drawings and accompanying examples. Some of the drawings can include logic flow. Although such drawings presented here may include certain logical flow, we can understand that the logical flow simply provides an example of how the common functions described here can be implemented. In addition, given the logical flow does not necessarily have to be performed in the order presented, unless otherwise is indicated. In addition, given the logical flow can be implemented using the hardware element (elements), programme element (elements)by one or more processors, and any combination of these. Options for implementation is not limited to this context.
Traditional conveyor graphic video processing includes the display content that is passed in memory frame buffer system in the platform processing, and then provides data (data frames)transmitted to the device's display via the usual interface of the display. Examples of such conventional interfaces include the video graphics adapter (VGA), digital visual interface (DVI), multimedia interface HDMI, display port (DP) and analog TV formats. In turn, the device display then manages the display, using the received data frame. This is based on the moments of time that can be managed using the Boolean funds under the platform processing or in the device display.
After taking the device display uses its internal logical tool to expand Delta and save uncompressed data in its own frame buffer. In addition, the device display can handle various operations such as local update of the screen display, zoom, rotate and turn on/off the display. Because these technologies are used in common interfaces, multiple display devices can be supported (limited buffer size frame platform processing and bandwidth of its processing).
Unfortunately, such operations o read and compare (which run platform processing) require a significant amount of processing-processing platform. For example, for video with high intensity of the applied action may be required, in essence, all the ability to handle the typical processing platform (for example, a personal computer).
Thus, this approach is different disadvantages. One drawback is that the platform processing has no data on the output from the frame buffer and does not use the advantages of remote frame buffer. As a result, processing platform uses no bandwidth and processing power by building and maintaining their own frame buffer in its global local storage device.
Another disadvantage of this approach is that translation and reading frame buffer processing platform (for example, using software rejection frame of a third party) is an open place in the security system. For this reason, the software of third parties can capture any content frame (such as content containing personal data) and send them anywhere. Thus, such a rejection of the frame will probably be banned in the future.
In variants of implementation of such shortcomings overcome the advantages of displays that have integrated frame buffers. For example, options for implementation, processing platform can have a pipeline (conveyors) graphics processing, which imply remotely set the frame buffer and include this remote frame buffer as part of the overall process of conveyor graphics processing and ensure reliable preservation of detention from the time of its formation until the display. Remote frame buffer can be connected via any digital interface, and if you want encryption of content, can be adopted appropriate encryption method interface.
Thanks to the inclusion of the concept of remotely located frame buffer processing platform can only offer data Delta from frame to frame, eliminating, thus, the need for the above mentioned operations comparison of the frame to frame. Additional options for implementation may determine whether to compress or not to compress such data before sending them through the interface. Such determination may be based on the available bandwidth of the interface. For example, compression can be used to USB 1.0 and USB 2.0, but not for USB 3.0.
Figure 2 shows the approximate scheme variant 200 implementation, which can be incorporated into the pipeline graphics processing, such as any of conveyors graphics processing of figure 1. Such implementation may include different elements. To illustrate (and not to limit) figure 2 shows the mechanism 201 receive image data, the module 214 management frame buffer, the buffer 216 frame and module 218 data interface. These elements can be embodied in any combination of hardware and/or software.
The mechanism 201 receive image data generates data frame from the input image data 220. The mechanism 201 receive image data can be presented in different ways. Figure 2 shows mechanism 201 receive image data, which includes the module 202 conversion module, 204 lighting, 206 module installed, the module 208 ROP, the module 210 texture module 212 processing pixel.
As shown in figure 2, the mechanism 201 obtain accepts input image data image data 220 module 202 conversion. Input of graphical data 220 contain representations of scenes in model space (for example, the three-dimensional space). In variants of implementation of the input 220 graphics data can be taken from one or more applications (for example, through the graphic API ()).
Module 202 conversion converts coordinates in the input image data 220 from model space to the space of the screen. In addition, the module 202 conversion executes operations such as testing of the clip and any operation of the formation of the clip.
Module 204 lighting expects vertex colors, based on predefined colors of materials and the vertex normals. If necessary it can include one color to the top. Module 206 installation calculates the slope of the edges of the primary colors, and gradients (changes in directions X and Y) on the parameters of depth, color and texture.
Module 208 rasterization finds all valid sampling pixel for primary colors and calculates the correct depth, color and texture in each sample point. Module 210 texture searches one or more component values textures from a mass storage device texture and performs operations offsets are specific to the texture of the color of the incoming pixel.
Module 212 processing pixel performs operations that occur once per pixel, such as comparison of depth, pixel offset and other similar operations. As a result, the module 212 processing pixel provides 214 management module frame buffer pixel data that represent the contents of an image one screen.
Module 214 management frame buffer performs operations related to the conservation of pixel data. For example, a module 214 management frame buffer determines whether to store the pixel data locally in the buffer 216 frame, or whether to transfer the data of the pixel in the frame buffer in the display device (such as a device 103 display).
Module 218 data interface provides access to the interface that connects to a display device (such as an interface 105 figure 1). For example, a module 218 data interface can provide the interface with the data pixel (taken either from the buffer 216 frame, or directly from the module 214 management frame buffer). In addition, the module 218 data interface can accept (through the interface) the management information provided by the device display. Such data control can indicate whether the device display buffer (the buffer) frame. In variants of the implementation of the data management can be in the data structure that describes the capabilities of the display device, such as the extended data identification display (EDID). However, you can use other data formats.
As shown in figure 2, the module 218 data interface provides the module 214 management frame buffer such information management. For example, figure 2 shows the module 218 data interface, which provides the module 214 management frame buffer indicator 222 frame buffer and indicator 224 bandwidth interface. Indicator 222 frame buffer indicates that includes whether a device display the frame buffer. Indicator 224 bandwidth interface indicates throughput (bandwidth) interface-processing platform that works with your device display. In variants of the implementation of such an indicator can set the interface type (for example, USB 1.0, USB 2.0, USB 3.0, and so on). However, you can use other indicators bandwidth.
On the basis of such indicators module 214 management frame buffer determines how to process the generated data frame. For example, if the connected device's display has an integrated frame buffer, it saves the generated data frame in local buffer 216 frame. In line with this, such locally stored data frame will be transmitted to the display device in accordance with standard technology display interface (for example, VGA, DVI, HDMI, DP, TV etc).
In contrast, if the connected device's display has an integrated frame buffer the module 214 management frame buffer transfers data frame (for example, "Delta" or contrast to the previous frame) in the device display (via module 214 interface and connected interface) to preserve its integrated frame buffer. Such data frame is passed on the basis of bandwidth interface. For example, for interfaces higher throughput data frame (e.g. Delta) can be transmitted in uncompressed format. However, for interfaces with low bandwidth, data frame (e.g. Delta) can be transmitted in a compressed format. Options for implementation, however, is not limited to this example.
In addition, the module 214 management frame buffer can encrypt the data frame, designed for transmission via the interface (via module 218 data interface). Different encryption technologies can be used, such as standard a mechanism (s) of encryption used by the interface between the platform processing and display device. In line with this, the device display (for example, control module)can decrypt such data after administration.
Figure 3 shows a diagram of logical flow of 300, which can be performed in one or more variants of implementation. This flow includes rendering platform, which has one or more pipelines graphics processing, and display device that has one or more buffers frame. Thus, this thread can be performed with use of the elements shown in figure 1. However, options implementation is not limited to this context. Although figure 3 shows a specific sequence, the other sequences can be used. In addition, the operation can be performed in different parallel and/or serial combinations.
In block 304 platform processing determines the throughput (bandwidth) interface. On the basis of this platform processing defines the format for data transmission frame in box 306. For example, for low bandwidth platform of treatment can determine whether to use a compressed format for data transmission frame. However, for higher throughput platform processing can determine whether to use an uncompressed format for data transmission frame.
In variants of implementation capacity may be determined by the type of interface being used. For example, the USB 1.0 and USB 2.0 can be regarded as interfaces with lower bandwidth (which leads to the transfer format with compression). In contrast, USB 3.0 and LAN (for example, Ethernet) can be regarded as interfaces with higher bandwidth, resulting in transfer format without compression. However, options for implementation are not limited to these examples.
Thus, in box 307 platform processing generates a data frame and passes them through the interface to be displayed in accordance with the selected transfer format.
As described above, unit 308 performed if the display device does not have an integrated frame buffer. In line with this, the unit 308 platform processing generates the frame data and stores them in its own frame buffer. In the context of figure 2, it can contain a module 214 management frame buffer that contains the data frame generated by 200 option implementation, in the buffer 216 frame.
After this, there is a block of 310, in which platform processing passes locally stored data frame in the display device in accordance with standard technology display interface (for example, VGA, DVI, HDMI, DP, TV etc).
As described above, options for implementation may provide multiple frame buffers within the display device (such as a device 103 display). For example, figure 1 shows a device 103 display having buffers 111a and 111b of the frame. Between so many buffers frame can be maintained complete isolation. Thus, each frame buffer in the display device can be assigned to different treatment (treatment options) or operation (transaction). For example, each frame buffer can be assigned a specific OS or one or more specific applications. In addition, as described above, processing platform (such as platform 101 processing) may include a set of pipelines graphics processing. In variants of implementation of each of the many conveyors can be routed to the appropriate frame buffer device display.
Figure 4 shows a schematic, representing an approximate allocation of the frame data in the context of figure 1. In particular, figure 4 shows the pipeline a graphics processing, providing a stream of data 420 frame buffer 111a of the frame, and the conveyor 106b graphics processing that ensures the flow of 420b data frame buffer 111b of the frame. With reference to figure 1, these data streams frame can be part of the data 120 frame and information 122 management. In variants of implementation flows 420 and 420b the frame data can be transferred across different connections (for example, isolated compounds), provided interface 105. Alternatively, the same connection can be used for all data frames. However, within such connection data frame mark for their respective buffers frame in the source (for example, in the platform processing). Using the scheme mark can be defined by selecting the user in the device display. Thus, in the variants of implementation can be achieved in isolation from the device display (for example, the control module in the device display).
Threads 420 and 420b data frame may be different contexts user (for example, different processes or operations platform 101 processing). For example, a thread 420 data frame may correspond to processes (for example, applications) is the first operating system running on the platform 101 processing, while the flow 422 data frame may correspond to processes (for example, applications) second operating system running on the platform 101 processing. In addition, the flow 420 data frame may correspond to the first group of one or more applications, while the flow 422 data frame can match the second group of one or more applications. These application can be distributed in any way among one or more operating systems. In variants of implementation of the applications or operating systems may have information about their respective frame buffer.
Options for implementation may provide isolation between threads data frame. This isolation can be provided through a lot of connections provided by the interface. For example, in the context of USB interfaces can be shared by each data stream of the frame (and its corresponding information management) through one or more channels USB. However, can use other technologies of formation of the interface and/or isolation. In addition, each frame buffer device 103 of the display can be "fixed" thread-specific data frame, so that it cannot be re-appointed without permission of the user.
This approach may be preferable to give the user a convenient way to switch back and forth between different content displayed on the device display. In addition, this approach provides a reliable way for personal content. For example, this approach provides an opportunity for a secure OS and user's share of the monitor (display device). In addition, this approach can provide the ability to quickly switch between environments without complex switch or display memory.
Figure 5 illustrates the logic flow of 500, which may represent the operations performed in one or more variants of implementation. This flow includes platform processing and display device. Thus, this thread can be done elements, shown in figure 1. However, options implementation is not limited in such a context. Although figure 5 shows a certain sequence can use a different sequence. In addition, presents operations can be performed in different parallel and/or serial combinations.
In block 502 user determines the selection of operations processing platform for multiple frame buffers in the device display. For example, the user can select the processes of the first operating system for the first frame buffer and processes the second operating system for the second frame buffer.
In block 504 isolated connections, frame buffers are established for each selection. For example, one or more channels USB can be installed for each selection. Alternatively, one or more of tunnels Internet Protocol (IP)that can be set for each selection.
Thus, in the block 506 the frame data for selected operations pass through the appropriate communication (connection) in the device display. Such data receive and retain in their respective frame buffers in the device display unit 508.
Block 510, the user selects the frame buffer for output using the display. In variants of the implementation of this may imply the user interacts with the user interface of the device display. However, options implementation is not restricted to this example. On the basis of this device selection of the display outputs the contents of the selected buffer frame in the block of 512. As indicated in figure 5, the operation may return to the block 510, where the user changes the selection frame buffer for output in the block of 512.
As described above, options implementation can provide a display device having a buffer (the buffer) frame and non-volatile storage medium. For example, figure 1 shows a device 103 display, including buffers 111a-b frame and nonvolatile media 114 information. This property provides efficient processing power States. For example, when you go to a lower power (for example, suspension of power supply, the device's display can save the contents of your clipboard (buffers) of the frame in the non-volatile storage media. On the contrary, when you return to the state of the higher power, the display device can record saved contents back into its frame buffers.
Such properties preferably possible to overcome the shortcomings of conventional approaches. For example, conventional approaches do not provide such non-volatile saving in the device display. In addition, for display devices that have a frame buffers, conventional approaches do not contain frame buffer in the appropriate platform processing. Thus, in order for the device display to log in this state of low power (for example, a suspend state power), handling framework should consider the contents of the frame buffer back of the device display and save the content in their own non-volatile storage media. Unfortunately, this may require excessive amounts of energy and time.
Unit 602 handling framework specifies that you want to change the power state (for example, the event of system goes into standby mode). In particular, handling framework defines the transition from the first (higher) power status to the second (lower) nutritional status. This definition can be based on any one or more of the triggering conditions (for example, a user inactivity, low battery and so on). In versions of the event the system is in standby mode can be a state of transition in the idle state C3 or C4 in accordance with the specification of the Advanced management interface configuration and power interface (ACPI). Options for implementation, however, is not restricted to these approximate States.
Based on this definition, the platform processing (in block 604) to send a Directive to change the power state of the device display. In the context of figure 1, the exchange of this Directive may be carried out through the interface 105 as information 122 management.
The display device accepts this Directive in the unit 606. In turn, the device display determines that the submission of the working power in its buffer (the buffer) frame must be suspended. In accordance with this unit 608 device display saves the contents of this buffer (the buffer) (for example, data frame) in its non-volatile storage media. After that the display device can enter directed the status of the power 610. In the context of figure 1, performance units 606-610 can be controlled by the module 112 management.
In block 612 platform processing determines what should happen additional power state changes. In particular, handling framework defines what should happen transition from the second low power state to a higher state power. In variants of implementation, this could mean a return to the first state power. Alternatively, it may be a transfer to another higher power status.
In accordance with this unit 614 platform processing passes the Directive in the device display. With reference to figure 1, this Directive can be transmitted through the interface 105 as information 122 management.
The display device accepts this Directive in box 616. After taking the device display provides food for work in its own buffer (buffer) frame in box 618. In turn, in the block 620 device display copies the saved contents of non-volatile storage device back into your buffer (buffer) frame. Thus, the frame data recording into a buffer (the buffer) frame. In the context of figure 1 performance units 616-620 can be controlled by the module 112 management.
As described here, the options for implementation may provide a display device having an integrated frame buffers. This can be done in a local storage device display frame. In addition, options implementation unit display (e.g. device 103 of the display) can have a table maps frame (FMT) in its local memory mapping of the frame. FMT able to manage his memory in such a way that it may not be divided into many independent frame buffers that display on one physical display.
Such property preferably allows you to selectively use a large display that provides a single sense when viewed, or "split screen", providing the feeling of many independent mappings. For example, the user can divide the screen in half (for example, either horizontally or vertically)to get the perception independent mappings. In addition, the user can dynamically switch between the perception of one display and perception of many independent mappings.
It is specified that each monitor, added to the business, increases productivity by 50%. Thus, this property is preferable provides to the user the opportunity to get a sense multiple monitors using one monitor. Thus, such a property, preferably, left space on the table.
In addition, FMT may include field labels assosiated with blocks of storage device display display that protect blocks from each other, and provides the ability to allocate memory for various operating systems, applications, and/or users.
In variants of implementation FMT manipulated using the user interface on the device display. This is different from the environment of the window because the management FMT does not depend on user interfaces provided by relevant platforms processing (for example, a platform 101 processing).
Such choice of the user (for example, multiple monitors and one monitor), leads to different output resolution. Thus, for the provision of the properties of the device display provides a platform processing the permission information (based on the user's choice) through the interface that connects these items (for example, interface 105). Such information about the resolution may be provided in different formats, such as structure (structure) EDID data.
As described above, with reference to figure 1, the device 103 display includes media 110 information, which provides the first buffer 111a frame and a second buffer 111b of the frame. 7 shows the scheme of alternative layout, which uses FMT. In particular, 7 shows the media 110' of information that can be used in a display device, such as a device 103 of the display.
As shown in Fig.7, media 110' information includes space 702 frame buffer, which can be flexibly allocated to provide one or more buffers frame. Such flexibility in the allocation is determined FMT 704. For example, figure 7 shows that FMT 704 allocates space 702 frame buffer in the first section 706 of the frame buffer and the second section 708 of the frame buffer. However, in the variants of implementation FMT 704 can allocate space 702 frame buffer in a separate part of the frame buffer or any many sections of the frame buffer.
On Fig shows the flow pattern 800 logical processing, which may represent the operations performed in one or more variants of implementation. This thread provides a platform processing, display device having one or more buffers frame and non-volatile storage medium. Thus, this thread can be performed with the help of the elements in figure 1. However, options implementation is not limited to this context. Although Fig shows a specific sequence, the other sequences can be used. In addition, the operation can be performed in the form of various parallel and/or serial combinations.
In block 802 display device accepts a user's choice to output one or more data streams display in his physical display. For example, the choice of the user can be a single data stream frame (feeling one monitor). Alternatively, select the user can submit the conclusion of many data streams frame (the feeling of many monitors). In addition, the user can refer to output formats (for example, next to each other, tiling above, below, and so on). This choice can be passed through the user interface of the display device (for example, through the interface 113 user of figure 1).
Based on user selection in the device display highlights (in block 804) plots save the frame buffer in the media. For example, in the context Fig.7 such areas would be within the space 702 frame buffer. In addition, the selection may include the generation of a FMT.
In block 806, the device display indicates the information transmitted in the processing device on the choice of the user. This information can mean the selected data streams personnel. In addition, such information may indicate the information permits (on the basis of the user's choice). Options exercise of such information may be transmitted through the interface between the platform processing and display device (for example, interface 105).
In block 807 platform processing accept the information transmitted in the block 806. On the basis of such information, the platform processing generates the selected flow (flow) data frame in accordance with the notation (for example, in accordance with the value (values) of the resolution). In addition, the platform processing passes the selected data streams frame through the interface. As described here, each data stream frame can be transmitted through the appropriate connection (for example, isolated connection), which provides an interface.
The display device accepts the selected data streams frame in box 808. In turn, the display device stores the data frame allocated on the respective section (sections) of your media in block 810.
On this basis, the device display displays the selected flow (flow) data frame in accordance with the user's selection in the block 812.
As described here, different variants of implementation can be implemented using the elements of hardware, software elements or any combination of them. Examples of hardware elements may include processors, microprocessors, diagrams, circuit elements (such as transistors, resistors, capacitors, inductance coils and so on), integrated circuits, application-specific integrated circuits (ASIC), programmable logic device (PLD), digital signal processors (DSP), logframe, user-programmable (FPGA), logic gates, registers, semiconductor devices, integrated circuits, crystals, chipsets, etc.

For example, some variants of implementation can be described with the use of the terms "connected" and/or "connected"to indicate that two or more of the element are in close physical or electrical contact with each other. The term "connected", however, may also mean that two or more of the element are not in direct contact with each other, but still interact and influence each other.
