METHOD FOR TRANSMITTING HIERARCHICAL SCALABLE VIDEO CODING DATA THROUGH NETWORK CODING, A DEVICE THEREOF, A RECEIVING METHOD, AND A DEVICE THEREOF FOR SUPPLYING UNEQUAL ERROR PROTECTION TO THE HIERARCHICAL SCALABLE VIDEO CODING DATA WITHOUT SUPPLYING ADDITIONAL RESOURCES

摘要

PURPOSE: A method for transmitting hierarchical SVC(Scalable Video Coding) data through network coding, a device thereof, a receiving method, and a device thereof are provided to improve a decoding success rate of base layer data having the highest significance when the hierarchical SVC data is transmitted.;CONSTITUTION: A data transmission device receives hierarchical SVC data from a source node(610). The data transmission device decodes the hierarchical SVC data and performs network coding of the decoded hierarchical SVC data while differentiating a data inclusion frequency corresponding to significance(620). The data transmission device transmits the hierarchical SVC data to a destination node(630).;COPYRIGHT KIPO 2013;[Reference numerals] (610) Receive hierarchical SVC video data from a source node; (620) Decode the hierarchical SVC video data while differentiating a data inclusion frequency corresponding to significance and network-code; (630) Transmit the network-coded data to a destination node; (AA) Start; (BB) End
