Abstract
A digital video and audio data recording and/or reproducing apparatus includes a plurality of rotary magnetic heads provided in association with a tape guide drum assembly having a periphery about which a magnetic tape is helically transported at a predetermined wrap angle, a time compressing circuit for time compressing digitized audio and video data, a multiplexing circuit for mixing the digitized audio and video data to form a mixed signal, a processing circuit for processing the mixed signal, and a signal distributing circuit for supplying the processed mixed signal to each of the rotary magnetic heads so that the latter record the processed mixed signal on the magnetic tape.
Claims11
Digitized video and audio data recording and/or reproducing apparatus, comprising:
- a tape guide drum assembly having a periphery about which a magnetic tape is adapted to be helically transported at a predetermined wrap angle;
- at least one rotary magnetic head associated with said tape guide drum assembly for recording digitized video and audio data on said tape;
- time compressing means for time compressing said digitized audio and video data;
- multiplexing means for intermixing said time compressed digitized audio data and video data in a time sharing manner to form an intermixed signal;
- processing means for processing both said audio data and video data by processing said intermixed signal;
- and
- distributing means for supplying said processed intermixed signal to said at least one rotary magnetic head.
Information signal recording apparatus comprising:
- converting means for converting an audio signal and a video signal into digital form;
- multiplexing means for intermixing said digitized audio signal and said digitized video signal in a time sharing manner to form an intermixed signal;
- processing means for processing both said audio and video signal by processing said intermixed signal;
- and
- transducer means for recording said processed intermixed signal on a record medium.
Information signal reproducing apparatus comprising:
- transducer means for reproducing an intermixed signal which is formed by intermixing a time compressed digitized audio signal and a time compressed digitized video signal in a time sharing manner and which is recorded on a record medium;
- processing means for processing both said audio signal and video signal by processing said reproduced intermixed signal;
- and
- separating means for separating said digitized video signal and said digitized audio signal from said processed intermixed signal.
