Abstract
In a communication network (), a video encoder/decoder system () and an encoding method () facilitate transmission of video frames () over multiple low-data-rate channels (). Frame data () is generated for each video frame (). The frame data () is transformed () to obtain transform coefficients (), which are assembled () into quadtrees () and separately coded (). In addition, motion vectors () are split into coding blocks () and separately coded (). The quadtrees () and the motion vectors () are independently distributed among the multiple channels () for transmission. A decoding method () facilitates error resilient reception of transform coefficient packets () and motion vector packets () so that lost transform coefficients () and/or lost motion vectors () can be estimated at a receiving video encoder/decoder system () to reconstruct a received video frames
