This application claims the priority of provisional patent application U.S. No. 60/788,466, filed March 31, 2006.

The technical field to which the invention relates

The present system relates to the effects of ambient light that accompany the events leading system.

The level of technology

The company Koninklijke Philips Electronics N.V. (Philips) and other companies have developed a tool that is designed to change the surrounding or peripheral lighting to improve video content for a typical home or business applications. It was shown that the ambient lighting, the modulated video content, which is provided together with the video display or TV, reduces fatigue of the viewer and enhance the realism and depth perception. Currently, Philips has developed a line of TVs, including flat-screen TV with ambient light, where the frame around the TV includes ambient light sources, which are projecting external light on the back wall, which are based or located next to it. In addition, the light sources located separately from the TV can also be modulated depending on the video content to create ambient lighting, which can be controlled in the same way.

In the case of a monochromatic source of light, m is dolaze such a source may represent only the modulation of its brightness. A light source capable of creating multi-color light, provides the possibility of modulation on many aspects of multi-color light source based on the video being played, including a wide range of selected colors for each point.

The invention

The purpose of this system is to overcome the disadvantages existing in the prior art and/or the effect of creating ambient lighting for events leading system that does not directly relate to the content of the video being played.

The present invention provides a method, program and device for the control element of the ambient light. According to one variant of the invention, the detected event host device retrieves the lighting scenario associated with the detected event, and the extracted lighting scenario is reproduced in accordance with the detected event. The management element of the ambient light may be carried out depending on the playback lighting scenario. The user can associate the lighting scenario with the event and/or event type that corresponds to this event. In one embodiment, may be provided with the default relationship for events and/or event types, although these connections by default, can be modified uses the user. The event type that corresponds to a given event can be identified, and the lighting scenario associated with the identified type of event may not be played back depending on the detected event.

In one embodiment, with lighting scenario can be associated with additional data. In this embodiment, the playback of the extracted lighting scenario can include the playback of the lighting scenario in accordance with the additional data. These additional data may modulate the characteristics of a reproduced scenario lighting, including color, intensity and/or the playback speed of the lighting scenario. In this way, additional data is modulated color, intensity and/or speed of the corresponding effect of the ambient light.

The lighting scenario can be repeated in sequence, leading to repetition of the controlled effect of the ambient light. The relationship between events and/or event types and lighting scenarios can be stored in a table that can be modified by the user.

Detailed description of the invention

The following describes illustrative embodiments of which, when considered together with the accompanying drawings, demonstrate these features and advantages, as well as several additional. In the following description for purposes of explanation and not limitation, specific details are set forth for example a particular architecture, interfaces, techniques, etc. to illustrate. However, specialists in the art should be obvious that the scope of the attached claims are other options that deviate from these specific details. In addition, omitted for clarity, detailed descriptions of well known devices, circuits, and methods, so as not to obscure the description of the present invention.

It should be clearly understood that the drawings included here for illustrative purposes, and they do not represent the scope of the present invention.

Figure 1 shows a block diagram 100 of a sequence of operations according to a variant implementation of the present invention. During steps 110 to start the process, which may begin as a result of activation, e.g. the inclusion the master of the ambient light. It is assumed that when used herein, the term "host device ambient light" or simply "host device" includes a device that has features and/or characteristics that are unrelated to the creation of external lighting. For example, the master device may be a TV, monitor, audio player, personal digital assistant (PDA), cell phone, home appliance and other devices. The host device may include a system of ambient light in accordance with the embodiment of the present system or may simply be associated with the specified system ambient lighting. Action 110 may also begin the activation function of the ambient light by a user of the host device. For example, a user at some point in time you may decide to activate or re-activate a function of the ambient light in accordance with the embodiment of the present invention. Of course, a function of the ambient light may be enabled by default in response to the enabled state without intervention or action of the user.

In any case, during the 120 system according to one variant of implementation enters the idle state to determine detected and the event host device. It is implied that used here, the term "event" includes manipulation and adjustment functions of the host device and/or circumstances, which draws the attention of the user either intentionally or as a result of some event. For example, the event may include an on/off master, change the settings in the host device, the input/output function settings, confirm selection options/settings/mode and/or other similar operations of the host device. Other events can simply be foreseen, for example, when the host device is turned off, you can anticipate a future event, consisting in the inclusion of the master device, and thereby it is possible to prepare for future work, the lighting scenario that corresponds to the expected event, as described here. Expected events can also occur when the system receives the trigger data. For example, the broadcast system may send an emergency alert in the system. The information received by the master device, may lead to expected or unexpected event. In another or the same embodiment, the system may be configured to receive from the communication network, some of the information for this system according to the instructions of the user. If to is Yes, the event is not detected or is not inevitable, the system according to the present invention can remain in a wait state, or, in other words, step 120 may continue.

According to the present invention after the discovery of the event or unavoidable event, the present system identifies this event and/or event type while 130. Once identified event and/or event type, the system, according to one variant of implementation, retrieves the lighting scenario, which corresponds to a given event and/or event type in the duration of 140.

Lighting scenarios, associated with video content, audio visual master unit, which generated inside or outside the master device is known; for example, they are disclosed in international patent application No. IB2006/053524 (Case attorney No. 003663), filed on September 27, 2006, the rights to which are owned by the assignee of the present invention and the contents of which are entirely incorporated in this application by reference. The lighting scenario plays to control the effects of ambient light, for example, the job and/or change color, intensity, duration, and/or other characteristics of the effects of the ambient light.

According to the present invention, the lighting scenario constructed in accordance with the event and/or event type. In one embodiment, in the memory m which may be stored in the event table and/or event types, are available ambient light. This table may contain a list of events and/or event types and lighting scenarios corresponding to these events and/or event types. In the system according to one variant embodiment of the invention uses such a table, and to identify and retrieve lighting scenario, which corresponds to a given event and/or event type, use the identified event or unavoidable event.

During the 150 present, the system plays the appropriate script coverage before, during and/or after the event. Play lighting scenario leads to the effect of ambient light under the control of the lighting scenario. Play lighting scenario can be configured and/or set the effect of the ambient light, for example to set and/or change the color of the ambient light, its intensity, duration, and/or other characteristics of one or more elements of the ambient light, for example, the lighting elements of the present system of the ambient light. In one embodiment, the lighting scenario can determine the sequence of pre-edited lighting effects that appear in the play of lighting scenario. When detected Eisbein event, the step 150 may be performed immediately before the occurrence of the event may be delayed until, until there came an event, or may appear directly after the event. For example, the lighting scenario for inclusion can be played after you enable the host device. After playing back the script, the lighting, the present system may return to step 120, waiting for the detection of subsequent events and/or unavoidable events.

For example, the playback of the corresponding scenario lighting, such as lighting scenario for on/off, can be running in this event as turning on or off the host device. This lighting scenario can create the effect of ambient light, which continues throughout phase on/off. For example, the effect of ambient lighting under the control of the lighting scenario for inclusion may continue until the point in time when the host device is turned on and ready for operation, for example, during the entire period of the program startup, or any portion thereof. The lighting scenario for inclusion can provide a favorable view (effect) lighting in the form of accession to the effects of ambient light, related to videopreteen, for example, for the traveling devices representing the TV. In one embodiment, one or more characteristics of the lighting effect may begin with muted colors, such as color, intensity, etc) with smooth transitions, and then line up (e.g., increase) in time, creating the expected continuous effect of ambient light during audiovisual performances on television. During the outage, the effect of ambient lighting under the control of the lighting scenario for off may continue until the point in time when the host device completes the shutdown or during some of this time. In one embodiment, the effect of the ambient light created by the use of lighting scenario to turn off, can gradually fade, such as color, intensity, etc. up until this effect ends.

In one embodiment, the lighting scenario for some event and the corresponding effect of the ambient light can act as a response to an event from the master. For example, in the case when the user changes the setting of the host device, may be reproduced scenario confirming coverage in effect warning light, such as the effect of the ambient light, and/or done is of consistent intensity changes from medium to high. As an example, in response to an event such as a change relative to important functions, for example, a change in the function code lock to protect from access by children, can play the effect and/or the sequence of the red ambient lighting, such as relatively rapid reproduction of the ambient light. In other cases, an event such as changing more and more everyday functions, such as setting the time of day, can lead to the effect and/or the sequence of blue light, for example, with a relatively slow sequential change of the ambient light. In this way can be edited one or more scripts confirming lighting, in order to emphasize the importance discovered in the moment or unavoidable events. In one embodiment, the same scenario confirming lighting and/or script warning light may be reproduced as when changing important functions, and change ordinary function with the only difference consisting in varying the speed of execution of the sequence within the entire lighting scenario, and this rate plays the role of an indicator of the importance of changes to this function. Thus, a more rapid execution of a sequence of lighting scenario and the corresponding effect by the program can be used to indicate change relatively more important functions.

During the event the installation can be created by the effect of "marching" lighting script for marching lighting. For example, the effect of marching lighting may include one or more rhythmic sequences of colors, intensities, and/or other characteristics of the ambient light. An event that causes a delay in the further work of the host device, such as a blanking period of the display device of the host device, may cause the effect of the ambient light to the waiting state, created as a result of lighting scenario to the waiting state. The effect of ambient light to the waiting state can be a simple sequence of one or more characteristics of the external light, for example, a sequence for color lighting on - off - on", etc. In one embodiment, the lighting scenario for the waiting state, for example, to create the effect of ambient light, similar in feeling the ticking of the metronome, when the ticking is replaced by one or more characteristics of the effect of the ambient light, which is followed by periodically, for example, a sequence of two States, which includes "on - off", two colors (for example, "red - blue)""high intensity h is ska intensity" and other similar sequences of the ambient light.

In this way, the event or event type can be associated with a given lighting scenario, the playback speed of the given lighting scenario and/or sequence of performance of the lighting scenario. According to the present invention for creating data of the ambient light, including data for controlling the characteristics of the ambient light, such as hue, saturation, brightness, color, intensity, rate of change, etc. of one or more elements of the ambient light. Other lighting scenarios, playback speed and/or of the execution sequence of lighting scenarios, etc. can be associated with other events related to the master device that it is obvious to experts in the given field of technology.

As described earlier, events, types of events and/or other data related to the playback speed of lighting scenario can be associated with the lighting scenarios within the reference table. According to one variant of implementation in this table may initially be the default communication. These links can be modified according to one variant of implementation of the present invention. In another embodiment, events and/or event types may be present in the table without ties to lighting scenarios. In this embodiment, communication can be set up, if appropriate the change and/or modified.

Figure 2 shows a block diagram 200 of a sequence of operations illustrating editing operations in the event table, which also can include the types of events and associated lighting scenarios according to one variant of implementation of the present invention. During steps 210, the user manipulates the user interface in accordance with one embodiment to enter the part of the user interface for editing tables. The table is scanned during steps 220, including visible events and/or event types corresponding to the lighting scenario, and, if available, the additional data relating to the reproduction of the respective lighting scenarios. Lighting scenarios can be represented in the table names that identify the potential use of lighting scenario. For example, a particular lighting scenario can be identified by the name "warning", indicating that this particular lighting scenario you can apply for the event, which should carefully be taken into account, for example, a change in the function code lock to protect from access by children, as described above. Other names that may appear as a hint to the user, can be used as names of lighting scenarios in tab is itzá to facilitate the correct choice of lighting scenarios for communication with the event and/or event types, as it is obvious to experts in the given field of technology.

In one embodiment, the table may be a set of events and/or types of events of default and related lighting scenarios, which can be determined by the manufacturer of the specified host device. In addition, communication can be established automatically based on the available set of lighting scenarios. In this embodiment, the event, for example, pertaining to a combination lock to protect from access by children, may not be associated with the lighting scenario, if the link was not previously provided and there is a lighting scenario type "warning". After providing the host device of the lighting scenario of type "warning" mentioned the connection with an event related to a combination lock to protect from access by children, can be provided automatically. In this and/or alternative embodiment, the link may be created and/or modified manually by the user, as described below.

The user, for example, after viewing the table can determine whether to modify the table while 230. If the user decided not to modify the table, then during the term of 270 exits the part of the user interface of the host device, intended for editing tables. Uses the user the opportunity to modify and/or add an event the type of event and communication with the lighting scenario during the term of 240. If the user chooses to modify the part of the table relating to Affairs, then during the action 250 and 252, the user can select an event and/or event type, and then modify and/or to identify the lighting scenario for communication with the selected event and/or event type. For example, the user may select the link for the event with the lighting scenario that had no connection. The user can change the connection by selecting a different lighting scenario for communication with the event and/or event type. In one embodiment, the event type, for example a significant change in the functions of the host device, may be associated with the selected lighting scenario. Thus, there is no need to associate each possible event with a particular lighting scenario for lighting scenario to be reproduced during this event. In one embodiment, the playback of a particular lighting scenario associated with the type of event may be cancelled by the bond of a specific event with a different lighting scenario. Thus, the user can select specific links, at his discretion.

In one embodiment according to the present invention with an event you can also link audiocontent. The audio content may be provided as part of the lighting scenario and/or may be provided simply to communicate with the lighting scenario. In this embodiment, the event host device causes the playback of the corresponding script, lighting and audio. The audio content can be played back synchronously with the lighting effect as the result of the play of lighting scenario. The connection of the audio content with the event and/or event type you can also select/modify while 252.

The modification process compliance events and/or event types to lighting scenarios can be repeated until then, until it is determined that it is necessary to save the table while 260. The process can be completed during the term of 270.

If the user decides not to modify the communication event with the lighting scenario during the 240, it may be given the choice and modification of the lighting scenario and/or data relating to the reproduction of the lighting scenario, during the action 280 and 290. First select the lighting scenario, which can then be modified. Modification of the lighting scenario may include the modification of the characteristics of the lighting scenario, including color, intensity, duration, and/or other features such as the istics of the lighting scenario, which provide control effect of ambient light (e.g., managing one or more elements of the ambient light), which is created by the play of lighting scenario. In addition, in the General case can be modified data relating to the reproduction of the lighting scenario for the impact of an event that is associated with the script, lighting, and/or modified to change the playback script coverage for specific, related events. For example, can be modified data related to the playback speed of the lighting scenario. Additional data, modification of which is possible, can relate to how many potential devices ambient light is controlled in this scenario, the lighting, and/or to the selection of colors, intensity, etc. Can be other modifications known to experts in the art, and it is assumed here that they are not beyond the scope of this invention.

In any case, in addition, can be selected lighting scenarios for modification, and/or may be set according to the lighting scenario event and/or event type. Further, any modification can be stored during steps 260 and during the term of 270 exits editing operations is ablity.

Lighting scenarios can be created outside the system, for example, a service author create lighting scenarios, which provide the scenario of lighting on a fee basis and/or for promotional purposes. For example, lighting scenarios can be provided to activate a specific event, such as the choice of services provided to the master device. In this embodiment, the lighting scenario can be provided to activate this service through a master device. Paid embodiment, lighting scenarios for events can be provided on the media and/or through a connection such as a wired or wireless connection with a remote server, such as access to them can be done by connecting via the Internet. It is not difficult to understand can be provided script coverage for events using paid for services. In one embodiment, the lighting scenario can be provided in the intermediate system to boot to the host device, for example, through the synchronization process. In one embodiment, when the lighting scenario for the event is created outside the system, it can be executed in the format in which the system it plays directly on one or more devices of the ambient light. The lighting scenario is for the event can also be encoded in a predetermined format. This format may be such that gives pre-priori information for decoding and playback is started on one or more devices of the ambient light. For example, in one embodiment, the specified encoding can be achieved in scenario markup language. The script in the markup language may be embedded, for example, information received by the system. In one embodiment, this information may be obtained in the framework of data sent during synchronization.
