Abstract:
1. A method performed on a video stream having a plurality of video frames, the method supporting wireless transmission of an encoded version of the video stream, the method comprising: performing a mathematical operation on a first data block of a first video frame to generate a first check value; performing the mathematical operation on a second data block of a second video frame to generate a second check value, the first check value and the second check value represented with a lesser number of bits than the first and second data blocks, respectively; comparing the first check value and the second check value to identify static video content, including determining if the first check value and the second check value are equal or substantially equal; in response to static video content, generating an indication of static video content for use in decoding a portion of the encoded version of the video stream corresponding to at least one of the first data block or the second data block; and wirelessly transmitting the encoded version of the video stream, wherein the indication of static video content is a short code that is transmitted in lieu of a portion of the encoded version of the video stream corresponding to at least one of the first data block or the second data block.
