PURPOSE: A method for coding a video in an error resilient mode is provided to reduce the loss of information and have a high error resilient mode, and to provide a recording medium readable by a computer, so that communication less sensitive to an error is performed under an environment generating lots of errors such as a wireless communication channel. CONSTITUTION: In a data partitioning step(20), macro blocks including header data, motion vector data and DCT(Discrete Cosine Transform) data are partitioned to an HDP(Header Data Part) grouping the header data, an MVDP(Motion Vector Data Part) grouping the motion vector data, and a DDP(DCT Data part) grouping the DCT data. In a VLC(Variable Length Coding) step(22), parts of the HDP, MVDP, and DDP are VLCed. In an RVLC(Reverse VLC) step(24), RVLC is performed for parts selected in predetermined priorities. And in a marker inserting step(26), an RM(Resync Marker) for classifying each video data packet, an HM(Header Marker) for classifying the HDP and MVDP, and an MM(Motion Marker) for classifying the MVDP and DDP are inserted. |
