A data recording and reproducing apparatus which can easily perform the editing of audio and/or visual data even at the camera site. In the data recording and reproducing apparatus, a VTR portion and an MO disc portion are integrally constituted. Audio and/or visual data input from an outside apparatus is recorded on a video tape by the VTR portion, and further reproduced from the video tape and transferred to the MO disc device at a high speed and recorded. The user of the data recording and reproducing apparatus quickly finds the desired video image by actively utilizing the random access property of the MO disc device and sequentially inputs the same to the VTR device, records the same on the video tape, and performs the editing of the audio and/or visual data.

Data recording and reproducing apparatus

Data indicative of a transfer mode of a transmission packet may be inserted into a payload portion contained in a serial digital transfer interface (SDTI) transmission packet. Also, data indicative of a timing mode of the transmission packet may be inserted into this payload portion. As the transfer mode, there may be provided a synchronous transfer mode and an isochronous transfer mode in addition to an asynchronous transfer mode. A timing mode may prescribe a timing mode in which a transmission packet may be transferred in synchronism with a field of a transmission frame. There may be provided a normal mode using a first field, an advanced mode using a second field and a dual mode using both fields. Depending upon the manner in which the timing mode is set, a system delay between the transmission and the reception can be minimized.

Data recording and reproducing apparatus having a data transferring device for selectively transferring data between multiple data recording and reproducing devices

This invention relates to a data transmission method or the like for use in transmitting video data, audio data or the like. There is transmitted a serial digital transfer interface transmission packet in which an interval of each line of a video frame comprises an end synchronizing code area into which an end synchronizing code is inserted, an ancillary data area into which ancillary data is inserted, a start synchronizing code area into which a start synchronizing code is inserted and a payload area. Into the payload area, there are inserted first data containing extension data having stream information and second data containing main data comprising video data and/or audio data at the picture unit of video data. The stream information is information which indicates whether or not the picture unit belongs to a pre-roll interval located ahead of an editing interval, whether or not the picture unit belongs to an editing interval and whether or not the picture unit belongs to a post-roll interval located behind an editing interval. A reception side becomes able to positively edit data on a VTR, for example, by effectively utilizing the stream information.

Data transmitting method and data transmitter

Video data controllers and disk array units are connected with an independent input serial transmission line and an independent output serial transmission line. Data is serially transmitted between the video data controllers and the disk array units. Data of the video data controllers is sent with time slots assigned thereto. Data has a synchronous signal at the beginning thereof. The synchronous signal synchronizes with time slots. The synchronous signal is followed by commands/status and video data.

Data recording/reproducing apparatus, data recording/reproducing method and data format

A recording and reproducing device comprises a plurality of hard disks H,through Hp, an error checker,for detecting write errors produced in the respective hard disks H,through Hp, a memory,for storing therein a logical address for the hard disk H,from which the write error is detected, and a computing unit,for recovering data to be recorded on the write error-detected hard disk H,, based on data recorded on other hard disks H,, H,and Hp from which no write errors are detected. When the logical address for the write error-detected hard disk H,is designated, the post-recovery record data is outputted. According to this, since the write error of each hard disk, which has occurred upon writing, can be automatically corrected, the present device can be continuously activated without missing continuity for a request for recording and reproduction of video/audio data.

This invention relates to data input/output apparatus and the like, which are suitable to be applied to an AV server. As nonlinear accessible storage medium, there is provided with HDD array device (,). When a controller (,) of an AV server (,) receives a command for reproducing data from a minimum of two discontinuous areas in the HDD array device (,) in a first order, the HDD array device (,) then puts the command in an order such that a period of time for access is minimal to reads the data so that the read data are rearranged in the first order to be outputted through decoders (,) to (,). Thereby, the efficiency of data transfer is improved without complications.
