Abstract
A system and method for wireless communication of video data are disclosed. One embodiment of the system transmits partially compressed video data from a transmitter to a receiver over a wireless channel. The transmitter is configured to send a plurality of groups of data bits over a wireless channel. The data bits, in an uncompressed form, together form one or more displayable elements representing at least a portion of a video image. The plurality of groups have different degrees of significance to the quality of the video image. The plurality of groups include a first group of uncompressed data bits, and a second group of compressed data bits, wherein the first group has a higher degree of significance to the quality of the video image than the second group. The receiver is configured to receive the plurality of groups of data bits over the wireless channel. The system allows transmission of a large amount of video data over a wireless channel having a limited capacity or a varying condition.
