    摘要： A connection control equipment can 9 connect a plurality of calls originating from a terminal (1 - 3) to a private side terminal (10 - 12) by identifying the calling terminal.
    Construction: Each of user terminals (1 - 3) sets a calling number and a calling sub-address or a user-to-user information for identifying the terminal in a call-setting message. A switching system 9 of a connection control equipment receives the call-setting message and stores the calling number and the calling sub-address or the user-to-user information in the message and connects the call to a private side terminal with which the same user terminal issuing the just received call is communicating. The switching system 9 can connect calls from the same user terminal to the same private terminal, allowing for any user terminal to freely transmit a plurality of calls without considering how to access a host computer 20.

    摘要： The present invention relates to a video storage type communication device for use in a video information communication system for distributing video data to remote terminals over a communication channel to which the terminals being connected. This communication device comprises a receiving portion 31 for receiving first coded video data over the communication channel, a first storage portion 32 for storing the first coded video data received by the receiving portion, a video generating portion 34 for re-encoding the first coded video data received by the receiving portion 31 to generate second coded video data different from the first coded video data, a second storage portion 33 for storing the second coded video data generated by the video generating portion 34, a reproduction control portion 35, 37 for selecting the first coded video data stored in the first storage portion 32 or the second coded video data stored in the second storage portion 33, and a transmitting portion 38 for transmitting the first coded video data or the second coded video data selected by the reproduction control portion over the communication channel.

    摘要： A video storage type communication device which is capable of storing coded video data received from a terminal and reproducing 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 which comprises a transmitting portion (17) for transmitting video data and a receiving portion (11) for receiving video data over a communication line, a video storage portion (15) for storing received video data and a communication control portion (14) for carrying-out video-communications by controlling the above-mentioned portions. The device is further provided with a refresh image detecting portion (12) for judging, from the received coded video data, whether the received coded information is a refresh image, a storage control portion (13) for storing into the video storage portion (15) the coded video data received by the receiving portion (11) by previously adding thereto inter-frame or intra-frame prediction coded information detected by the refresh image detecting portion (12) and a terminal control portion (20) for sending at a desired interval a request for updating display image through a communication control portion (14) to a terminal during storing video information.

    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.
