Abstract
A method and system for enhancing transmission reliability of video information over a wireless channel is provided. The video information includes pixels, each having a plurality of components and each component including video information bits that are placed in sub-packets within a packet. Error detection information is determined for one or more sub-packets, and placed in the packet. Then the packet is transmitted from a transmitter to a receiver a wireless channel, wherein the receiver uses the error detection information per sub-packet to check for transmission errors and request retransmission of erroneous video information bits based on their perceptual importance.
