    摘要: A video data processing apparatus includes a reading unit reading video data from a video data file recorded on a randomly accessible storage medium in response to a first control signal, and reading position data indicating a frame position of the video data in the video data file from the video data file recorded on the storage medium in response to a second control signal, a memory storing the position data read by the reading unit, and a controller controlling the reading unit by outputting the second control signal before the outputting of the first control signal, and controlling the reading unit by outputting the first control signal with a designation of particular video data to be read indicated by the position data stored in the memory, in response to a request to execute a process to the video data file.

    摘要: In a video data processor, the control unit cyclically defines a plurality of slots to the data bus, sets band width of each slot to be band width capable of transmitting the video data without missing frames, and assigns the video data to the slots. Only the video data of slots assigned by a bus arbiter may be received transmission permission in a round-robin system, then, the video data of the slots is transmitted to the data bus. Thereby, the band of the data bus may be efficiently used without affecting on transmission of video data of which the transmission speed should be kept constant.

    摘要: A demand assign multiplexer has a multiplexing portion multiplexing a signal which can be transmitted in a statistical multiplexing. Also, the multiplexer has an output element for outputting a channel assignment demand depending upon a signal from a system which requires guarantee of transparent data transfer which guarantees content of transfer in a normal state of a transmission path. A control portion controls to perform demand assign process with channel assignment depending upon the output of the statistical multiplexing processing portion; and the signals which require guaranteed transparent data transfers.
