    • The present invention provides a moving picture re-encoding apparatus, which can generate correct reproducible encoded data by a light-load simple process when encoded moving picture data are converted or edited. It is provided with: a decoding means 12 that decodes frames of a moving picture from an encoded bit stream; a frame selecting means 15 that selects a frame to be re-encoded from the decoded frames; an encoding means 14 that re-encodes only the selected frame; and an interval notifying means 13 that calculates a frame interval, after the re-encoding of a frame, between the frame and a next frame to be re-encoded to notify the decoding means of the calculated frame interval. The decoding means 12 decodes the bit stream for time based on the notified frame interval after the notification from the interval notifying means 13. The frame selecting means 15 selects the last frame as the next frame to be re-encoded among the frames until the time passes.

    • 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.
    • 视频存储型通信装置存储从终端接收的视频数据,并且以与端子规格无关的终端的任意期望的帧速率进行快速转发或反转再现所需要的视频信息。 视频存储型通信设备包括用于发送视频数据的发送部分和用于通过通信线路接收视频数据的接收部分。 视频存储部分存储接收的视频数据。 通信控制部分通过控制上述部分来执行视频通信。 刷新图像检测部分从接收到的视频数据中判断所接收的视频数据是否是刷新图像。 存储控制部分根据刷新图像检测部分的确定将帧间或帧内预测编码信息添加到接收的视频数据,并将接收的视频数据存储在视频存储部分中。 终端控制部分在存储视频信息期间以期望的间隔发送通过通信控制部分更新显示图像的请求到终端。

    • 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.

    • Packets received through a network interface 104 is stored into a receiving buffer 108. Are production controller 106 checks the current state of receiving buffer 108 and performs a reproduction process mentioned below. The data in receiving buffer 108 is transferred to a decoder 109 in accordance with instruction from reproduction controller 106 and decoded as voice sound, D/A converted by a D/A converter 110 and then output as voice sound from a speaker 102. The clock for D/A conversion is supplied from a reproduction clock CLK 107. This configuration is free from overflow and underflow of the receiving buffer due to difference in clocks between the transmitting and receiving ends, and prevents the occurrence of packet jitter so as to avoid voice sound breaks.
