METHOD FOR CONTROLLING ERROR OF VIDEO BIT STREAM DATA IN WIRELESS MULTIMEDIA COMMUNICATION AND RECORDING MEDIA THEREFOR

摘要

PURPOSE: A method for controlling an error of a video bit stream data in a wireless multimedia communication and recording media therefor is provided to efficiently control the error of the video bit stream data by adding a CRC(Cyclic Redundancy Code) to the bit stream data coded by a data partitioning method. CONSTITUTION: Each of separated region is classified each other using a specific marker when a video bit stream data is coded by a data separate method(40). Each of separated region is searched through the marker when a CRC of each of separated region is calculated(41). A packet is transmitted to a destination through a wireless channel, and the transmitted packet is received in a receiving terminal of the destination(43,44). The packet received in the receiving terminal is demultiplexed for a decoding, and a CRC field of the received video bit stream is checked before the demultiplexed video bit stream is inputted to a decoder(45).
