Wireless Communication Techniques

Abstract

Wireless communication techniques are described. In one or more implementations, techniques are described that involve active power control such that a device may bypass use of a power amplifier to communicate wirelessly. In one or more additional implementations, wireless communication techniques are described in which multiple bands may be leveraged to provide wireless communication. In one or more further implementations, wireless communication techniques are described in which a frame buffer on a receiving device is leveraged by a sending device. Yet further, in one or more implementations wireless communication techniques are described in which a sending device employs codec adaptation. Still yet further, in one or more implementations, wireless communication techniques are described which may be used to change characteristics of a channel used to communicate data. Yet further again, in one or more implementations, a receiving device is configured to adjust a display based on wireless communications received from a plurality of devices, such as to leverage a display by multiple wireless sources.

What is claimed is: 
     
         1 . A display device comprising:
 one or more modules implemented at least partially in hardware, the one or more modules configured to perform operations comprising:
 receiving two or more streams wirelessly at a display device from respective two or more computing devices; and 
 automatically portioning a display area of the display device such that content from the two or more streams is displayable concurrently by the display device. 
   
     
     
         2 . A display device as described in  claim 1 , wherein the display device is configured for use as a three-dimensional display and content from a first said stream is viewable using a first pair of three-dimensional viewing glasses but not a second pair of three-dimensional viewing glasses and content from a second said stream is viewable using the second pair of three-dimensional viewing glasses but not the first pair of three-dimensional viewing glasses. 
     
     
         3 . A display device as described in  claim 1 , wherein data communicated via the two or more streams is formatted by respective said computing devices based at least on a respective portion via which the data is to be displayed by the display device. 
     
     
         4 . A display device as described in  claim 3 , wherein the reformatting includes adjusting an aspect ratio or resolution to approximate an aspect ratio or resolution of the respective portion. 
     
     
         5 . A display device as described in  claim 1 , wherein the portioning is performed such that one or more portions are resizable using picture-in-picture techniques. 
     
     
         6 . A display device as described in  claim 1 , wherein the portioning is performed to control shutter glasses. 
     
     
         7 . A display device as described in  claim 1 , wherein the content from the two or more streams is displayable concurrently by the display device such that at least a portion of each of the two or more streams overlaps. 
     
     
         8 . A method comprising:
 determining by a sending device that a second frame that is to be transmitted by the sending device to a receiving device includes at least a portion that is a repeat of a corresponding portion of a first frame that was transmitted by the sending device to the receiving device; and   responsive to the determination, causing at least a portion of the first frame, which matches the portion of the second frame, of the received device to be repeated for display by the receiving device without transmitting the portion of the second frame by the sending device.   
     
     
         9 . A method as described in  claim 8 , wherein the receiving device employs a buffer that stores a copy of the portion of the first frame that is to be repeated. 
     
     
         10 . A method as described in  claim 8 , wherein the causing is performed without transmitting controls signals or frames by the sending device to the receiving device. 
     
     
         11 . A method as described in  claim 8 , further comprising responsive to the determination, entering a sleep mode by one or more hardware devices of the sending device until an update to the first frame is to be transmitted to the receiving device that includes content that is not included in the first frame. 
     
     
         12 . A method as described in  claim 8 , further comprising responsive to the determination, reducing a transmission frame rate of the sending device to the receiving device. 
     
     
         13 . A method as described in  claim 8 , wherein the sending device employs one or more extender concepts such that:
 a video stream is sent independent of a user interface stream; and   updates for a subsection of a display that include the video stream are transmittable without sending an update to the user interface stream.   
     
     
         14 . A method as described in  claim 13 , wherein an audio stream is sent independent of the video stream and the user interface stream such that an update to the audio stream is transmittable by the sending device without sending an update to the user interface stream or an update to the video stream. 
     
     
         15 . A method comprising:
 receiving two or more streams wirelessly at a display device from respective two or more computing devices; and   automatically portioning a display area of the display device such that content from the two or more streams is displayable concurrently by the display device.   
     
     
         16 . A method as described in  claim 15 , wherein the display device is configured for use as a three-dimensional display and content from a first said stream is viewable using a first pair of three-dimensional viewing glasses but not a second pair of three-dimensional viewing glasses and content from a second said stream is viewable using the second pair of three-dimensional viewing glasses but not the first pair of three-dimensional viewing glasses. 
     
     
         17 . A method as described in  claim 15 , wherein data communicated via the two or more streams is formatted by respective said computing devices based at least on a respective portion via which the data is to be displayed by the display device. 
     
     
         18 . A method as described in  claim 17 , wherein the reformatting includes adjusting an aspect ratio or resolution to approximate an aspect ratio or resolution of the respective portion. 
     
     
         19 . A method as described in  claim 15 , wherein the portioning is performed such that one or more portions are resizable using picture-in-picture techniques. 
     
     
         20 . A method as described in  claim 15 , wherein the content from the two or more streams is displayable concurrently by the display device such that at least a portion of each of the two or more streams overlaps.
