This application is related to patent application U.S. RCA 87361 "Device screen display system for processing digital video signal", filed in the name of J. A. Cooper odnoy display system for processing digital video signal.

The device on-screen display (device for displaying information on the screen), used in systems video processing, contains a multiplexing scheme for switching signals representing a graphic image, and a normal television video signals so that the screen device to display the image, the graphic image can be displayed or instead of the image corresponding to the video signal, or in conjunction with this image (inserted). The graphical image may represent alphanumeric characters or graphics in the form of drawings and can be used to transmit information about the state of the system, such as a channel number, time, or work instructions.

In the devices screen display designed for use in systems processing analog video signal, the multiplexing scheme is usually switched to the levels corresponding to the desired intensity of the respective parts of a graphic image, in those moments when a portion of the graphics image to be displayed. In such devices, the signals representing a graphic image, have the form of pulses that come in those moments of willexamine. This analog indicating unit can be used in a system for processing digital video signal, but this requires that the signals were first converted to analog form. Since the processing system of the digital video signal typically contain unit digital-to-analog Converter in which the digital video signals are converted to analog form, it is economically more advantageous to include a display device, the display processing unit of the digital video signal.

The invention relates to a digital device screen display system for processing digital video signal and, in particular, for a system for processing digital video signal in which the digital video signals represent information about the image in compressed form.

More specifically, according to the invention a system for processing digital video signal receives encoded data packets carrying the information about the TV image in compressed form. For decoding and decompression of video packets with the formation of groups of digital words representing a television picture, video decoder is used with the corresponding video. In addition, the video decoder includes a display unit is carried out also in the video in the group of digital words representing a graphic image. Digital words representing a television picture, and the digital words representing a graphic image, together multiplexed under the control block screen display.

These and other aspects of the invention will be described with reference to the accompanying drawings, where:

in Fig. 1 depicts a block diagram of a digital satellite television, containing a block of digital signal processing, which includes as an integral part of a digital device screen display according to the invention,

in Fig. 2 depicts a block diagram that discloses the details of the digital video processing module with the device on-screen display system for digital satellite television, shown in Fig.1, and

in Fig.3 depicts a block diagram of a Converter used in a digital device screen display shown in Fig.2.

In the satellite system shown in Fig.1, the transmitter 1 with a corresponding transmitting antenna 3 transmits television signals including video and audio components on satellite 5, located in geosynchronous orbit. Sputnik 5 receives the television signal is contracted antenna system ("outer block") 7. Antenna system 7 includes an antenna 9 in the form of a plate and the Converter 11 frequency. With the antenna 9 of the television signals transmitted from the satellite 5, are fed into the Converter 11 frequency, which converts the frequency of the received television signals in the corresponding lower frequencies. Because the Converter 11 performs frequency conversion of the frequency band of the entire group received television signals, it is often called "batch Converter".

Of the group of transducer 11 television signals via a coaxial cable 13 are received in the receiver 15 of the signal from the satellite. The receiver 15 of the signal from the satellite is also called the "inner unit", because he is in the room. The receiver 15 of the signal from the satellite performs the selection, demodulation and other processing of the received television signal, as will be described in detail below, with the formation of audio and video signals in NTSC, PAL or SECAM), suitable for processing conventional television receiver 17 to which these signals are fed. In response to the video and audio signals, a television receiver 17 forms an image on the screen 19 and provides sound through loudspeakers 21a and 21b.

Ssiona information is transmitted in compressed form in accordance with a preset digital standard for example, the MPEG standard. MPEG is an international standard for coded representation of moving pictures and associated audio, which is developed by a group of experts at moving images.

More specifically, in the transmitter 1 analog video signals and analog audio signals are converted into digital signals. Digital video and audio signals are compressed and encoded in accordance with a compression standard and coding MPEG. In the encoded digital signals are in the form of a sequence or stream of packets corresponding to the video and audio components. The packet type is identified by the code header. In the data stream can be added to the packets corresponding to the management data, and other data.

In the MPEG video data is transmitted in the form of components (Y) luminance and two color difference components (U and V). For example, the first color difference component may represent the difference between the signal corresponding to the red image, and the luminance signal (R-Y) and the second color difference component may represent the difference between the signal corresponding to the blue image, and the luminance signal (B-Y). In addition, signment image. The use of color-difference component, and sharing the different elements of the image of one color difference component reduces the bandwidth of the signal being transmitted.

In order to perform the correction of errors that may occur due to possible noise in the transmission channel, to add data packages for direct error correction. It is preferable to use known methods of coding, Viterbi and reed-Solomon for forward error correction. Digital signal obtained as a result of compression, encoding, and adding data for error correction, modulate a carrier according to a method known in the art of transmitting digital information as quadrature phase shift keying.

The receiver 15 of the signal from the satellite contains a tuner 1501 with a local oscillator and a mixer (not shown) for selecting a set of signals received by the antenna system 7, a signal corresponding to the carrier and to reduce the frequency of the selected carrier signal is received intermediate frequency. The intermediate frequency signal is demodulated using demodulator 1503 quadrature phase manipulation with the formation of the demodulated digital signal. The decoder 1505 decodes data PR is and demodulated packets representing video, audio and other information. For example, if the transmitter 1 encoding with the purpose of error correction was performed according to the methods Viterbi and reed-Solomon, the decoder 1505 direct error correction can operate in accordance with algorithms Viterbi and reed-Solomon. Tuner 1501, the demodulator 1503 and decoder 1505 can be an integral part of the unit, manufactured by Hughes Network Systems (Germantown, Maryland) or Comstream Corp. (San Diego, California).

Unit 1507 routing represents a demultiplexer, which, via data bus sends the video packets of the signal after error correction, the video decoder 1509, and the audio packets in the audio decoder audio 1511, in accordance with the information contained in the packet headers.

Video decoder 1509 interacts with a single storage device 1513 random access performed, for example, in the form of dynamic storage device, for decoding and decompression of video packets with the formation of a stream or sequence of digital words representing the corresponding component (Y) and brightness components (U and V) citratest. The sequence of digital words representing the portions served on the device is, in the sequence of digital words representing the brightness signal (Y) and a sequence of digital words representing the chrominance signals (C), in accordance with the format horizontal and vertical scan of a conventional television standard, such as NTSC, PAL or SECAM. The encoder 1515 television signal generates signals horizontal (H) and HR (V) scans, as well as the clock signal (PC) for picture elements (pixels) which are fed to the video decoder 1509 to synchronize a sequence of digital words representing the components. With the help of relevant diagrams digital-to-analog Converter (DAC) 1517 digital word representing the luminance and chrominance are converted into analog signals of luminance and chrominance.

Audio decoder audio 1511 decodes the audio packets and performs decompression, and the resulting digital audio signal using a digital-to-analog Converter 1519 is converted into an analog low-frequency audio signal. Although in Fig. 1 shows only one audio channel, it is clear that, in practice, may be used one or more additional audio channel, for example, for stereo playback, as shown in the drawing posredstvennyi receiver 17 through its low-frequency inputs. Low-frequency analog video and audio signals are provided to the modulator 1521, which modulates an analog carrier signal of the radio frequency range in accordance with a television standard, such as NTSC, PAL or SECAM) to connect to the antenna input of a television receiver without the use of low-frequency inputs.

The microprocessor 1523 gives tuner 1501 management data frequency selection for tuning the tuner to the channel selected by the user. In addition, the microprocessor 1523 interactively communicates with the unit 1507 routing to control the routing of data packets. In addition, through the control bus of the microprocessor 1523 generates control data to the video decoder 1509 and audio decoder audio 1511.

Advanced microprocessor 1523 generates control data for display on the screen 19 of the television receiver 17 graphic images, for example, alphanumeric characters and/or picture graphs, for example, providing information about the system state or the operating instructions. Data graphics determine the color and position of each display element of a graphical image (pixel). The data of the graphic image pixel for pixel what would the rest of the device screen display was combined with the video decoder 1509 and the respective single storage device 1513 random access, which mainly used for decoding and decompression of the video data packets. These graphs are served at the video decoder 1509 through the control bus. As a result of such sharing video decoder 1509 and a single storage device 1513 random access there is no need for a separate device screen display. More device screen display will be described with reference to Fig. 2.

Video decoder 1509 performed in a single integrated circuit. Similar to the integrated circuit for decoding and decompression of the video, except for functions on-screen display, which will be described below, are available for sale. For example, integrated circuit decoding and decompression of the MPEG standard, the batch number ST3240, produced in France by SGS Thomson. As for understanding the on-screen display is not necessary in the detailed description of the nodes of the decoder 1509 associated with decoding and decompression of video data packets, it will be useful only brief descriptions of these sites.

Video decoder 1509 includes a source of digital packages, made in the form of buffer memory 1509-1 FIFO type (first-in - first-out), and which sends them through a single controller 1509-3 memory in the form of relatively large segments in the block 1513-1 single storage device 1513 random access, reserved for decoding and decompression. Addressing in a single storage device 1513 random access is controlled by a single controller 1509-3 memory. Block 1513-1 decoding and decompression of a single storage device 1513 random access buffer contains 1513-1-3 speed control data for storing the received video data packets and block 1513-1-2 for storing a frame of video information during the operations of decoding and decompression. Block 1509-5 reproduction of the television image performs decoding and decompression of the stored video packets with the formation of a sequence of digital words representing the components of a television image (Y, U, V). To this end, the block 1509-5 reproduction of the television image through a single memory controller 1509-3 requests the required data from the block 1513-1 decoding and decompression of a single storage device 1513. The generation of digital words representing the components of the video signal, synchronized with the signals horizontal (H) and HR (V) scans, as well as with a synchronizing signal (PC) for the pixels generated by the device 1515 encoding a television signal. Data management is Yuyu the control bus are routed to the various blocks of the video decoder 1509.

The number of bits in the digital word representing the component of the television image, determines the number of possible levels and, consequently, the resolution of the corresponding components. For n-bit words, there are 2npossible levels corresponding to 2npossible binary States. For example, in this embodiment, a word, a corresponding component of the television image, contains eight bits and, therefore, each component can have 28or 256 possible levels. The sequence of digital words representing the components of a television image, arranged in the component group, and each group corresponds to multiple pixels in seriescreative or compressed form. More specifically, in the present embodiment, each group representing a television picture corresponding to two pixels, and includes a first digital word (Y1representing the brightness of the first pixel, the second digital word (Y2representing the brightness of the second pixel, and one pair of digital words representing citratest (U1,2and V1,2) as for the first and second pixel. In the technique samples the data signal is a compression of the image data, which is carried out in the transmitter 1 in order to reduce the bandwidth of the transmitted signal. More specifically, the transmitted image data are in the format 4:2:0, in which words representing the image are for four pixels and four words represent, respectively, the brightness of the four pixels and one pair of words is citratest for each of the four pixels. In block 1509-5 reproduction of the television image group representing the image in the format of 4:2:0, with interpolation converted into groups representing the image in the format of 4:2:2. In the device 1515 encoding a television signal by interpolation for each pixel is formed a complete set of (4:4:4) component.

Part of the video decoder 1509 intended for on-screen display contains the display controller displays, in the form of block 1509-9 playback graphics, which interacts with a block 1513-3 the on-screen display single storage device 1513 random access. The bit map representing a graphic image generated by the microprocessor 1523, through the block 1509-7 interface microprocessor that serves as the source of qi is fasting device 1513 random access. For each pixel of the graphics image has a digital word representing the color pixel. The number of bits in the digital words representing the color determines how many different colors can have each pixel. If the words representing color, contain n bits, each pixel can have any of the 2ncolors corresponding to 2nthe possible States of n-bit words of color. For example, in the present embodiment, a word representing the color, contain two digits. Accordingly, each pixel graphics can have one of four colors corresponding to the four possible binary States (00, 01, 10 and 11) digit of the word color. Color information of a pixel arranged in the form of a component, in which for each word color has a unique group of digital words representing the component. Components are selected so that they coincide with the components used to transmit information about the TV image, namely the luminance signal (Y) and two color difference signals (U and V). Select the same component for television and graphic images by simplifying the on-screen display, because it eliminates need is, which uses double-bit words of color, there is the following correspondence between the digital words representing color, and groups of digital words representing components:

color - group component

00 - YAUAVA< / BR>
01 - YBUBVB< / BR>
10 - YCUCVC< / BR>
11 - YDUDVD< / BR>
Valid color (shown in the table indices A, B, C and D) graphics pixel depends on the values of the digital words representing the components of the corresponding group. For example, in the present embodiment, each of the digital words representing the components of the image, contains four digits. Four-bit words representing components that provide 16 possible levels for each component. These four categories represent four senior level eight-bit words, which ultimately formed in the block 1509-9 playback, graphic images, as will be described below.

From the microprocessor 1523 words representing the components of the graphical image, are transferred for storage in the block 1513-3 screen display of a single storage device in 1513 group company, in which each digital word representing a component of a graphical image contains four digits, each group consists of twelve digits. Color graphics can be changed by changing the four bits in one or more header words representing the component, depending on the nature of the displayed graphic image. In addition to these color management, the header contains control information for defining the beginning and the end of the graphic images in rows and columns of pixels.

Block 1509-9 playback graphics provides a reading of the bit display of the unit 1513-3 the on-screen display single storage device 1513 and converts the word representing the color of each pixel in the corresponding group representing the component header. For this unit 1509-9 reproduce graphic images through a single controller 1509-3 memory requests the required data from the block 1513-3 the on-screen display. Since in the present embodiment, a word representing a component of a graphical image, contain only four digits, while the words representing the component obrazom four-digit words, representing a component of a graphical image, in eight-bit words by a simple addition to the four-digit word four least significant bits with binary zeros. Generation unit 1509-9 playback graphics digital words representing a component of a graphical image, also synchronized signals horizontal (H) and HR (V) scan and clock signal (PC) for the pixels generated by the device 1515 encoding a television signal.

As noted above, the group representing the components of the television image, which are generated by the block 1509-5 reproduction of the television image, contain the video data in compressed form, in which each two pixels correspond to two words representing brightness, and one pair of words representing citratest, in the so-called 4:2:2. On the other hand, groups representing the component of the graphic image stored in the block 1513-3 the on-screen display single storage device 1513 random sample and generated by the block 1509-9 playback graphics, represent graphical information in the uncompressed form, in which for each pixel of their pixels, there are two words, representing brightness, and two pairs of words representing citratest). In the technique of processing a digital video signal of the last uncompressed format known as format 4:4:4. For signals of the graphic image sequence format 4:4:4 is desirable because it allows you to set the number of digits maximum number of colors for each pixel graphics, it provides a unique brightness component and two unique components of citratest. However, the sequence for the graphic image format of 4: 4:4 is incompatible with the sequence for the TV picture format 4:2:2 and can not be easily multiplexed with the latter so as to insert a graphic image in the TV picture.

To solve this problem, the video decoder 1509 contains the Converter 1509-11 the on-screen display for converting the sequence of format 4:4:4, used for component graphic image into a sequence of format 4: 2: 2, used for the components of the television image. As is illustrated in Fig. 2, for every two pixel graphic Converter 1509-11 couple chooses color component is 3, Converter 1509-11 may contain register-latch 1509-11-1 for storing two groups of words representing a component of a graphical image, and a multiplexer 1509-11-3 that with a speed corresponding to the frequency of the output signal, selects from the sequence stored in the register-latch 1509-11-1, appropriate words representing the components. It is desirable that the number of component groups, representing a graphic image format 4: 4: 4 and falling on one line, it was odd, because for the formation of each new group of graphic images in the format of 4:2:2 requires two of the original group of graphic images in the format of 4:4:4.

At that time it was considered the following sequence of components: the first component of the luminance (Y) for the first two pixels, the first component (U) of citratest for each of the two pixels, the second component (V) citratest for each of the two pixels and the second component of the brightness for the second of the two pixels may be used and other output sequence. For example, the output sequence can be generated in the following order: the first component (U) of citratest for each of the two pixels, the first component is ora component brightness for the second of the two pixels.

The multiplexer 1509-13, an output multiplexer, selects or group of words representing the components of a television image generated by the block 1509-5 reproduction of the television image, or group of words representing the components of the graphical image generated by the Converter 1509-11 the on-screen display running unit 1509-9 play graphics. In the output mode of the television image multiplexer 1509-13 selects only group representing a television picture. In output mode only graphics multiplexer 1509-13 selects only group that represents a graphic image. In the mode of "overlay", in which a graphic image is inserted in the television image, the multiplexer 1509-13 pixel by pixel selects or group representing the television image, or group representing a graphic image. From the output of the multiplexer 1509-13 received sequence of words format 4:2:2, which represents the components that feed into the machine 1515 encoding a television signal.

FIELD: engineering of systems for analyzing digital images, and, in particular, systems for showing hidden objects on digital images.

SUBSTANCE: in accordance to the invention, method is claimed for visual display of first object, hidden by second object, where first object has color contrasting with color of second object, and second object is made of material letting passage of visible light through it, where amount of visible light passing through second object is insufficient for first object to be visible to human eye. The method includes production of digital image of first and second objects with usage of visible light sensor. Digital data of image, received by computer system, contains both data of first object and data of second object, where data of first object and data of second object contains color information, and value of contrast between first and second objects must amount to approximately 10% of full scale in such a way, that along color scale of 256 levels the difference equals approximately 25 levels, then data of second object is filtered, after that values, associated with data of first object, are increased until these values become discernible during reproduction on a display.

EFFECT: creation of the method for showing hidden objects in digital image without affecting it with special signals.
