PICTURE ENCODING, RECORDING, AND REPRODUCING DEVICE

摘要

In a recording and reproducing apparatus with image coding for compression coding of digital video signals and for recording and reproducing the compressed code, digital video signals are divided on the screen into coding blocks which are overlapped (2) so as to share boundary pixels. DCT coefficient data in each coding block (3) are divided into a plurality of groups (4), and coefficient data in two coding blocks overlapping on the screen are recorded to separate regions on a recording medium. When an error has occurred during reproducing process, the state of error occurrence is analyzed (14) and an error correction (15) responsive to the state of error occurrence is performed on coefficient data that has been lost due to the error. Thus, a stable, successful reproduced image can be obtained even if an error occurs during recording and reproducing process. <IMAGE>
