Problems solved by technology

Therefore, standard quality video data (hereinafter referred to as standard definition (SD) video data) can be recorded by the MP@HL or MP@H-14 method, but HD video data cannot be compressed and recorded
[0004] Also, HD video data compressed by the MP@HL or MP@H-14 method cannot be effectively concatenated with data compressed by the MP@HL or MP@H-14 method

Embodiment Construction

[0037] Fig. 1 shows a typical structure of a recording system to which the magnetic tape recording and reproducing apparatus of the present invention is applied. The video data compression section 1 compresses the input HD video signal by the MPEG method such as the MP@HL or MP@H-14 method. The audio data compression section 2 compresses the audio signal corresponding to the HD video signal by a method such as corresponding to the MPEG2-ACC audio compression method. The controller 13 inputs system data formed of auxiliary (AUX) data, subcode data, and other data to the terminal 3.

[0038] The switch 4 is controlled by the controller 13 to appropriately select the output of the video data compression section 1, the output of the audio data compression section 2, or the system data input from the terminal 3 at a predetermined timing, and send it to error correction and ID detection Part 5.

[0039] The error correction and ID detection section 5 adds an error detection and correcti...

Abstract

A magnetic-tape recording apparatus records digital data on a magnetic tape by a rotating head. It includes a first obtaining device for obtaining predetermined-unit video data; a second obtaining device for obtaining audio data corresponding to the predetermined-unit video data; a synthesizing device for synthesizing the predetermined-unit video data and the audio data corresponding to the predetermined-unit video data such that they are continuous on a track in the magnetic tape without any space disposed therebetween; and a sending device for sending data synthesized by the synthesizing device to the rotating head in order to record the data on the magnetic tape.

Description

Technical field [0001] The present invention relates to a tape recording device and method, a tape reproduction device and method, and a recording medium, and particularly to a tape recording device, a tape recording method, and a tape reproduction that allow high-quality video data to be recorded on and reproduced from a tape and be effectively edited Device, tape reproduction method, and recording medium. Background technique [0002] Today, compression technology is making continuous progress. Video data is compressed and recorded on magnetic tape by methods such as Digital Video (DV). [0003] For example, in order to record high-quality video data (hereinafter referred to as high-definition (HD) video data), a bit rate of about 25 Mbps is required. In the conventional recording method, in addition to the rate of searching image data, the video rate corresponding to the Mp@HL Moving Picture Experts Group (MPEG) method is at most about 24 Mbps. Therefore, standard quality vide...
