[0001]    This application claims priority to U.S. provisional patent app. 61/179,304, filed May 18, 2009. 
     
    
     I. FIELD OF THE INVENTION 
       [0002]    Present principles apply to coordinating bezel illumination color in home entertainment systems. 
       II. BACKGROUND OF THE INVENTION 
       [0003]    Home entertainment systems come in a variety of colors, shapes, and sizes. One or more individual electronic pieces may make up the entertainment system. Often individual pieces of equipment work separately, such as a TV by itself, or can synchronize their functions to perform tasks that no single piece could accomplish, i.e. TV displaying a picture from a DVD player and sending its sound to a stereo system. 
       SUMMARY OF THE INVENTION 
       [0004]    As understood herein, synchronization of light sources mounted on each component allows for easily visible designation of the active component. 
         [0005]    Home entertainment systems may include a number of components in addition to a TV, such as a DVD player, Blue ray player, VCR player, etc. In order to visually distinguish which component is active, each is designated with a color of light emitted by a light source within the bezel of the component. The light sources may be disposed within any number of corners or as a decorative edge border on the front of the bezel. The TV contains a processor that synchronizes with an audio/video component when active as a light source(s) capable of emitting the colors specific to components. When a first component is active, its light source will emit light of a particular color and the TV&#39;s light source will emit light of the same color. 
         [0006]    Accordingly, a system includes a TV including a TV display framed by a TV bezel. At least one TV bezel light source is disposed in the TV bezel. Light from the light source passes through the TV bezel to be visible to a person. A first component communicates with the TV and has a first component bezel. At least one first component bezel light source is disposed in the first component bezel, with light from the first component bezel light source passing through the first component bezel to be visible to a person. The first component bezel light source emits light of a first color. Also, a second component communicates with the TV and has a second component bezel. At least one second component bezel light source is disposed in the second component bezel, with light from the second component bezel light source passing through the second component bezel to be visible to a person. The second component bezel light source emits light of a second color different from the first color. A processor causes the TV bezel light source to emit light of the first color when the TV presents information from the first component. In contrast, the processor causes the TV bezel light source to emit light of the second color when the TV presents information from the second component. Without limitation, the first component can be a disk player and the second component can be a home theater or a set-top box (STB) (cable, satellite, SSD server, etc) attached to the TV via a networking method including HDMI, LAN, wireless, etc. 
         [0007]    In another aspect, a method includes determining which one of at least two audio-video components is sending signals to a TV for display, and based on the determining act, establishes a color of a bezel of the TV. 
         [0008]    In another aspect, a TV has a display, a tuner receiving video signals for presentation on the display, and a processor communicating with the tuner. A bezel frames the display. First light sources characterized by a first color are positioned to illuminate the bezel from the interior of the bezel. And, second light sources characterized by a second color are positioned to illuminate the bezel from the interior of the bezel. The processor energizes the first light sources but not the second light sources to internally illuminate the bezel with the first color in response to the processor determining that it is receiving audio-video data from a first component. In contrast the processor energizes the second light sources but not the first light sources to internally illuminate the bezel with the second color in response to the processor determining that it is receiving audio-video data from a second component. 
         [0009]    The details of the present invention, both as to its structure and operation, can best be understood in reference to the accompanying drawings, in which like reference numerals refer to like parts, and in which:

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0013]    Referring initially to  FIG. 1 , a TV, generally designated  10 , contains a display screen  12  and is encased by a bezel  14 . The display  12  may be of any type and form, i.e. flatscreen LCD. The bezel material may be, but is not limited to, plastic. Internal components of the TV  10  include a tuner  16  used for receiving a signal, a medium  18 , and a microprocessor (MP)  20 . The processor  20  may be a TV processor and receives and interprets signals from other components of a home theatre system. 
         [0014]    A light source  22  is disposed within the bezel  14  of the TV  10  near the edge of the front panel of the bezel  14  in a decorative fashion, where light passes through the bezel  14  and can be seen by a person. The light source  22  may also be disposed in one or more corners of the bezel  14 . The light source  22  may use light diffusing techniques, and may include multiple triluminous LED&#39;s to create a color-customizable illuminated edge around the TV  10 . The light source  22  may emitted various forms of light including simple color, color patterns, and dynamic color patterns. 
         [0015]    Moving in reference to  FIG. 2 , the TV  10  is shown in a manner similar to that of  FIG. 1 , including a display  12 , bezel  14 , internal components  16 ,  18 , and  20 , and a light source  22 . An example non-limiting first component  24  of the same home theatre system that comprises the TV  10  incorporates a first component bezel  26 , a first component display screen  28 , and at least one first component light source  30  disposed within the first component bezel  26 . The first component  24  may be, but is not limited to, a disk player. The color of light emitted from the first component light source  30 , designated as first light color, passes through the first component bezel  26  and can be seen by a person. In some embodiments, multiple light sources  30  of different colors may be implemented for purposes to be shortly disclosed. 
         [0016]    An example non-limiting second component  32  includes a second component bezel  34 , second component display screen  36 , and a second component light source  38 . The color of light emitted from the second component light source  38 , designated second light color, passes through the second component bezel  26  and can be seen by a person. The second component  32  may be, but is not limited to, a home theatre or a set-top box (STB) (cable, satellite, SSD server, etc) attached to the TV via a networking method including HDMI, LAN, wireless, etc. In some embodiments, multiple light sources  38  of different colors may be implemented for purposes to be shortly disclosed. 
         [0017]    In one implementation, the processor  20  causes the TV bezel light source  22  to emit light of the first color when the TV presents information from the first component  24 , the bezel of which also emits the first color of light. Moreover, the processor  20  causes the TV bezel light source  22  to emit light of the second color when the TV presents information from the second component  32 , the bezel of which emits light of a second color. Both the component light source  30  and second component light source  38  may be disposed in any number of corners the corresponding bezel  26  or  34 , or as a decorative edging similar to that which may comprise the TV light source  22 . In any case, in this embodiment and assuming that the component bezels emit light of only a single color, the color of the TV bezel, which may be selected from a menu of colors by a user, is automatically established to match the color of light emitted from the bezel of the “active” component, i.e., the component that is sourcing content to or sinking content from the TV. 
         [0018]    In another embodiment, the TV bezel may emit a user-selected color of light, with the TV processor causing the controllers of the other components, which in this case have multiple colors of light sources in their bezels, to match the user-selected color of the TV bezel. 
         [0019]    Now referring to  FIG. 3 , a flow diagram is shown to demonstrate an embodiment of the method accomplished by the processor  20 . The TV  10  is linked to and communicates with the first component  24 . At state  40  the processor  20  determines whether the first component  24  is active. If the information presented to the processor  20  confirms the first component  24  is in fact active at block  42 , the light sources  22  and  30  are synchronized at state  46  in that they are caused by the one of the above processors, e.g., the TV processor  20 , to emit corresponding, preferably identical, colors, intensities, durations, synchronization, and/or synchronized sub-time. This may be done by simply causing the light sources in the TV bezel to emit only the color of light emitting by the light sources in the bezel of the component  24 , or vice-versa, i.e., by causing the light sources in the component bezel to emit only the color of light, preferably user-selected, emitted by the TV bezel. If the processor  20  determines that the first component  24  is not active (state  44 ), no action is taken to synchronize the light sources  22  and  30 . 
         [0020]    The processing for the second component  32  is identical. The second component  32  is analyzed for activity at state  48 . If the second component  32  is active (state  50 ), the light sources  22  and  38  are synchronized at state  54  as described above. If the processor  20  determines that the second component  32  is not active (state  52 ), no action is taken to synchronize the light sources  22  and  38 . Neither first component  24  nor second component  32  require a wired link with the TV as any networking (wired or wireless) may be used. 
         [0021]    While the particular BEZEL COLOR COORDINATION is herein shown and described in detail, it is to be understood that the subject matter which is encompassed by the present invention is limited only by the claims.
