摘要

If received coded video-data includes data with an error unable to be decoded or data disagreeing with ITU-T recommendation H.261 (e.g., the number of bits per frame exceeds the limit defined by the recommendation), it must be stored with due countermeasures taken against an error and inadaptable data, which allows the stored data to be effectively reproduced. Received coded video-data is decoded by a transmission-line decoding portion (31) and divided into frames by a data dividing portion (32), then it is decoded by an information-source decoding portion (33) and then intraframely encoded by a intraframe coding portion (34). According to a signal from a bit-counting portion (35) showing that the number of bits in one frame of coded video-data exceeds the limit defined by ITU-T recommendation H.261 or anomalous signal of a frame image decoded by the information source decoding portion (33), a frame-processing control portion (36) decides how to store each frame and controls a storable data transfer portion (37) to select intraframe-coded data and transfer the selected data to a data storage. <IMAGE>
