Video and audio recorder

Abstract

The invention discloses a video and audio recover, which comprises a host module and a sub-machine module. The host module comprises a control unit, a display unit, a video and audio input and output unit, a radio frequency receiving unit and a radio frequency transmission unit, wherein the control unit is connected with the display unit, a photographic unit, the video input and output unit, the radio frequency receiving unit and the radio frequency transmission unit respectively. The sub-machine module comprises a control unit, a display unit, a key unit, a decoding unit, a radio frequency transmission unit and a radio frequency receiving unit, wherein the control unit is connected with the display unit, the key unit, the decoding unit and the radio frequency transmission unit respectively; and the decoding unit is connected with the radio frequency receiving unit and the display unit respectively. The video and audio recorder comprises the host module and the sub-machine module, which transmit information to each other through radio frequency modules, so that the shortcoming that the conventional video and audio recorder only can display videos and audios on a host, and is low in concealment is overcome.

Description

technical field [0001] The invention belongs to the field of consumer application electronics, and in particular relates to the design of a video and audio recorder with a sub-machine. Background technique [0002] In the information age of our daily life, the recording and acquisition of video and audio has gradually become an important way for people to social activities, work, and various organizations or governments to understand external information. The rapid development of multimedia compression, network communication, large-scale integrated circuits, computers and other technologies has prompted the wide application of audio-visual systems to various fields such as finance, hotels, traffic management, shopping malls, schools, and factories. However, in existing video and audio recorder solutions, such as figure 1 Shown is a schematic diagram of the structure of the video and audio recorder in the prior art. Generally, the video and audio recorder can only perform vi...

Problems solved by technology

However, in existing video and audio recorder solutions, such as figure 1 Shown is a schematic diagram of the structure of the video and audio recorder in the prior art. Generally, the video and audio recorder can only perform video and audio display, playback and operation on the host computer, and cannot realize the remote control operation and monitoring of the video and audio recorder. Its operation is hidden. The performance and convenience of use are not ideal
