    摘要: A managing method for a multimedia file includes the steps of: generating index information including a source identifier expressing a source having one or more of management units associated with the multimedia file as a title frame, positions of a leading frame and tail frame of the title frame in the source, and a position of a reference frame for decoding the leading frame; and recording the index information onto a recording medium, attaching the index information to the multimedia file. The managing method for a multimedia file may include the steps of: causing a user to specify one or more of the management units associated with the multimedia file as a title frame; generating index information in which a bit stream obtained by encoding a specified title frame is embedded, and recording the index information onto a recording medium, attaching the index information to the multimedia file.

    摘要: The image processing apparatus includes a change detecting portion for outputting a first control signal indicating transition from a small change state to a large change state and a second control signal indicating transition from a large change state to a small change state between picture planes of input motion picture data, and an operation control portion for controlling starting and stopping of recording or transmission of input motion picture data according to the first control signal and the second control signal. During recording or transmission, the operation control portion controls to stop recording or transmission if the first control signal is not output until after a predetermined arbitrary time T1 elapses after the second control signal is output.

    摘要: A multimedia information recording device is used for efficiently recording multimedia information (100) file storage area (111) on a recording medium (110). From the multimedia information given to the device, a data body DB and control information (HD and FD) are created and given to a file storage area writing section (106) where the data is written in parallel at a time on a free cluster in the file storage area. In the free area of each cluster where the data is written, dummy data is packed by a dummy data adding section (107) to absorb the difference between the first position of a cluster and the first position of the data in the cluster. Thus, data rewriting to eliminate this difference is avoided. Information for connecting plural clusters where data is written is created by a multimedia information file creating section (108), and the multimedia information is recorded in a multimedia information file on the recording medium.

    摘要: A time-varying image editing device is provided on a recording medium (101) and used for editing time-varying image data reproduced from a time-varying image file containing time-varying image data body (111) the items of which are arranged together with time management information in temporal order and outputted. The device includes a file-to-be-reproduced extracting section (12) for extracting a desired reproduction part of a time-varying image file. The desired part contains a predetermined reproduction time. The device further includes a file creating section (17) for storing edit information (112) for managing the extracted reproduction part and the reproduction time in an area other than the one where the time-varying image data body is stored on the recording medium (101).

    摘要: 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.
