ABSTRACT:
A system and method for transmitting a video object used in generating a plurality of frames of a video sequence over a limited bandwidth channel to reduce latency associated therewith includes separating the video object into a plurality of segments each having a size based in part on the limited bandwidth of the channel, identifying and transmitting at least one of the segments necessary for generation of an initial frame of the video sequence, and generating and displaying one or more of the initial frames based on the segment. The system and method may also intentionally reduce resolution of one or more segments to meet timing requirements association with generation and display of the at least one frame of a video sequence. In this situation, a residual representation of the segment is transmitted when bandwidth is available to improve resolution and quality of the originally transmitted segment and object resulting therefrom.
