Abstract:
1. A method for communication, the method comprising: receiving, by a video processing device coupled to a display device via a communication link, video data from a video source; generating, by the video processing device, from a portion of the video data, a plurality of compressed video bit streams each comprising a different bit rate; selecting, by the video processing device, a first compressed video bit stream of the plurality of compressed video bit streams based on an operating condition associated with the communication link; communicating, by the video processing device, a first sub-frame of the selected first compressed video bit stream to the display device at a first frame size and a corresponding first number of bits per pixel; and dynamically adjusting, by the video processing device, the bit rate of the first compressed video bit stream during the communication of the first compressed video bit stream to the display device via the communication link by communicating a second sub-frame of the selected first compressed video bit stream to the display device at a second, smaller frame size and a corresponding second number of bits per pixel, responsive to one or both of a change of the operating condition associated with the communication link and a link performance of the communication link, wherein the ratio of the second number of bits per pixel to the first number of bits per pixel is greater than the ratio of the second, smaller frame size to the first frame size.
