    摘要: A communication (transmission) procedure control system according to the present invention, which is used for multiplex transmission of a plurality of media such as video and synchronous data over a transmission line between sending and receiving terminals and which, in the case either video FEC frame synchronization or data synchronization is lost and can not be restored whereas the ITU-T Recommendation H.221 frame alignment is maintained, can restore from the mismatched mode condition without interrupting the synchronous transmission of the information. The system comprises a video synchronization monitoring portion (11) for FEC video synchronization, a data synchronization monitoring portion (12) for synchronous data and H.221 synchronization monitoring portion (13) for frame synchronization of H.221 frames, a synchronization control portion (14) that is connected to the above-mentioned monitoring portions (11, 12, 13) to realize overall control of the synchronized conditions of every kind of information and makes an request for executing a mode-mismatch recovery procedure in the case that synchronization of any information was lost and could not be restored after the elapse of a specified time, and a transmission procedure executing portion (15) which is connected to the synchronization control portion (14) and executes the synchronization restoring procedure and the mode-mismatch recovery procedure.

    摘要: 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 1 - n. A coded video data received from terminals 1 - 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.

    摘要: The present invention makes it possible to execute communication between an image-information storage and a terminal even in case they have different image formats. An image data delivery request transmitted from any of terminals (11a - 11c) and received by a receiving portion (13) includes an information indicating that the terminal has a source format CIF or QCIF. This information is transferred to a communication control portion (14) which informs an source format control portion (17) of the source format CIF or QCIF of the terminal. When the terminal has the CIF source format, the required data transmitted from an image-information storage device (19) are transmitted through a transmitter portion to the terminal. When the terminal 11d has the QCIF source format, a part of the image data transferred from the image-information storage device (19) is extracted and converted into data of QCIF format by the source format control portion (17). The converted data of QCIF source format are then transmitted through a transmitting portion (15) to the terminal (11d).

    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: 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.
