Abstract： |
The video image information lost due to transmission error can be effectively recovered according to the dependence of time and space domain of video compressed data when digital video signals are decoded on receiving terminal. The method includes three steps; time domain compensatino in present frame or reference frame, block matched searching in the reference frame and error macro block hiding. By method of the invention, the reliability of video transmission in ground digital TV broadcasting system can be increased remarkably, so that technology of said inventino is one of reliable tehcnologys for ground digital TV broadcasting system. |
