METHOD FOR GENERATING XOR BASED REDUNDANT PICTURE SLICE AND ITS USING LOSS SLICE RESTORATION METHOD

摘要

A method for generating an XR(Xor Redundant) picture slice and a loss slice recovering method using the same are provided to recover a loss slice without an additional retransmission process although a slice is lost by generating an XR slice for important slices to be protected after compressing a moving picture and transmitting the generated XR slice. An XR slice application layer and an application range are set up(501). In the set XR slice application layer, the XOR operation of frames including at least one slice is performed in the set application range, and an XR slice is generated(502). When the generated XR slice is transmitted to a decoder, information of the set XR slice application layer and information of the set range are transmitted as a certain type.
