A device which is capable of storing moving picture data received from each terminal and providing each terminal with video information to be reproducible by rapidly forwarding or reversing at any desired speed independent of usable terminals. A video storage type communication device 30 with a receiving portion 35 and a transmitting portion 38 transmits and receives video data over a communication network 10 to and from each terminal l-n. A coded video data received from terminals l-n is stored as it is in a first storage portion 32 and, at the same time, the data converted into specially reproducible video information is stored in the second storage portion 33. At the time of reproducing, the reproduction control portion 35 controls the reproduction selector switch 36 to obtain the video data from the first storage portion 32 or the second storage portion 33, changing the reproduction mode from ordinary to the rapid forwarding/reversing and vice versa. The specially reproducible video generating portion 34 successively restores coded video data received through the receiving portion 31, encodes again the restored data by intraframe, interframe or still-picture coding method to generate video information to be reproducible in special mode such as reproduction by rapid forwarding or reversing.

Video storage type communication device for selectively providing coded

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 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 and divided into frames by a data dividing portion. Thereafter it is decoded by an information-source decoding portion and then intraframely encoded by a intraframe coding portion. According to a signal from a bit-counting portion 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, a frame-processing control portion decides how to store each frame and controls a storable data transfer portion to select intraframe-coded data and transfer the selected data to a data storage.

Video data storing device and method for coding video data based upon

A video storage type communication device stores video data received from a terminal and reproduces required video information by rapid forwarding or reversing at any desired frame rate at the terminal independent of the terminal specification. A video storage type communication device includes a transmitting portion for transmitting video data and a receiving portion for receiving video data over a communication line. A video storage portion stores received video data. A communication control portion carries out video communication by controlling the above-mentioned portions. A refresh image detecting portion judges, from the received video data, whether the received video data is a refresh image. A storage control portion adds inter-frame or intra-frame prediction coded information to the received video data in accordance with the determination by the refresh image detecting portion and stores the received video data in the video storage portion. A terminal control portion sends at a desired interval a request for updating a display image through the communication control portion to a terminal during storing of video information.
