摘要： The present invention provides an AV data recording apparatus and method that facilitate various processes concerning a recorded video, including continuous reproduction, digital transmission, file operation, partial deletion, and post-recording. The AV data recording apparatus divides an audio signal and a video signal into transport packets having a predetermined unit length, assembles a plurality of transport packets as one transport stream and executes recording. Accordingly, this invention enables managing whether a logical block is used or not, detecting a continuous data area comprising plural logical blocks that ensure realtime continuous reproduction, and determining logical block numbers of continuous data areas to be recorded. As a result, the transport stream is recorded continuously on a plurality of detected continuous data areas.

摘要： A helical scan type digital recording/reproducing apparatus arranged such that data corresponding to m fields/frames are divisionally recorded in n tracks on a magnetic tape and a slow, still or frame advance reproduction mode is effected in response to an instruction from an external input. The apparatus is equipped with a signal processing circuit coupled to a rotary head for inputting data reproduced from the magnetic tape by the rotary head to store the reproduced data in a memory. In response to the instruction for the slow, still or frame advance reproduction mode, the signal processing circuit outputs a control signal when the data corresponding to one or more frames/fields are stored in the memory. Also included is a servo circuit coupled through a signal line to the signal processing circuit to be responsive to the control signal from the signal processing circuit. The servo circuit controls a capstan motor in accordance with the control signal and the reproduction mode instruction.

摘要： In a disk camera, when additional information and moving picture information are managed as one file and recorded on an optical disk, useless area is minimized, thereby allowing effective use of recording capacity. A recording controlling part records continuously with respect to a logical block of the optical disk, at least one of input video and audio information in a packet format of a fixed length that is different from a data size of the logical block, and creates a data file for recording with respect to the logical block, additional information with respect to the video or audio information in the packet format of the fixed length. In this one data file, a fixed data size portion of the additional information is arranged in an area ahead of an area in which the video and audio information are arranged, and a variable data size portion of the additional information is arranged in an area behind the area in which the video and audio information are arranged.

摘要： An external expansion bus interface circuit is provided for connecting a peripheral to a micro control unit to exchange digital information under an external expansion memory mode of the micro control unit. For this purpose, the eternal expansion bus interface circuit includes a means for storing a writing data. Address decoder and a strobe decoder are connected to the micro control unit to directly receive the writing data, an address strobe, and a write strobe. Then the address decoder and strobe decoder produce a write enable signal for enabling the memory to store the data at address designated thereby.
