DISTRIBUTED VIDEO COMPRESSION SYSTEM

摘要

A distributed system for transferring compressed video from a limited-resources sending device to a receiving device. The sending device comprises: a camera for capturing a sequence of video frames; a subtracting unit for outputting the difference between the real pixel values and predicted pixel values as received from said receiving device; and a transmitter for transmitting to said receiving device said difference. The receiving device comprises: a memory for storing at least several frames older than the presently captured frame; a predictor for predicting the current pixel, and for transmitting said predicted pixel value to said sending device, and conveying the predicted pixel value to an adder; and a receiver for receiving from said sending device said difference between said real pixel and said predicted pixel; an adder for adding said difference and said predicted value, and for outputting as the sum the real pixel.
