Multimedia function of audio-visual device

Abstract

The invention provides a functional development of existing audiovisuals like radio, TV set, etc, to make them able to conveniently connect with Internet, home appliances or the similar products like microcomputer (PC), etc, to share resource and interactively control, especially largely enhancing the recording or replaying operability.

Description

Technical field [0001] Audio, video processing, control technology. Background technique [0002] At present, the real-time storage of civil radio and TV programs basically relies on tape recorders, video recorders, and camcorders with tapes as the medium. There are several major defects: 1. The forward and reverse rewinding time is too long, and the recording operation is complicated. The resulting standby state is not in place, which often delays the recording opportunity. 2. It is easy to miss recording and erase by mistake, and once it is mistaken, it cannot be remedied. Although there is an anti-erroneous erase mechanism, most of them are inconvenient to operate. 3. Low performance-to-price ratio of media, high price per storage capacity, short service life, short continuous recording time, and inconvenient use of submenus. 4. No interactive control (interaction) with audio-visual devices. 5. Recorders, video recorders, and analog camcorders will obviously fade out o...

AI Technical Summary

Problems solved by technology

There are several major defects: 1. The forward and reverse rewinding time is too long, the recording operation is complicated, the resulting standby state is not in place, and the timing of recording is often delayed

2. It is easy to miss recording and erase by mistake, and once it is mistaken, it cannot be remedied. Although there is an anti-erroneous erase mechanism, most of them are inconvenient to operate

3. The performance-price ratio of the medium is low, the price per unit of storage is high, the service life is short, the continuous recording time is short, and the submenu is inconvenient to use

4. No interactive control (interaction) with audio-visual devices

5. Recorders, video recorders, and analog camcorders will obviously fade out of the market, while the prices of better digital camcorders remain high, and it is difficult for digital TV to occupy most of the market in a short period of time
