Furthermore, the higher priority data of Coded Bit Pattern ( CBP) is separated from the DCT data in the same video packet and put in the beginning of each video packet to avoid the error impact from the DCT coefficients. 此外,将CodedBitPattern(CBP)的更高优先级的数据与在同一视频数据包中的DCT数据隔离开,并且放在每个视频数据包的开头以避免来自DCT系数的错误影响。
