Abstract:
1. A method of facilitating transmission of video frames over multiple channels in a communication system, said method comprising: for each of said video frames, generating frame data representative of said each video frame; transforming said frame data to obtain transform coefficients of said frame data; assembling quadtrees of said transform coefficients, each of said quadtrees including a group of said transform coefficients associated with an equivalent spatial location in said each video frame; separately coding said quadtrees to form coded quadtree coefficient groups, one each of said coded quadtree coefficient groups being associated with one each of a plurality of distinct spatial locations in said each video frame; and distributing said coded quadtree coefficient groups among said multiple channels for transmission, said distributing operation including assigning said coded quadtree coefficient groups to said multiple channels such that said coded quadtree coefficient groups representing adjacent ones of said distinct spatial locations in said each video frame will be transmitted over different ones of said multiple channels.
