Abstract:
In a method of transmitting a frame of video, a number of bits corresponding to a frame of video is determined. A length of time needed to transmit the number of bits is determined and is compared with a length of time corresponding to a frame period. A frame period may correspond to an inverse of an average frame update rate. If the length of time exceeds the length of time corresponding to the frame period, one or more P-frames including a plurality of empty macro-blocks may be transmitted and the frame of video may then be transmitted over period of time exceeding one frame period. In some cases, the transmission of the frame of video may equal two or more frame periods. The transmitting may include transmitting an instruction for setting a latency in a client device to less than 50 ms.
