Embodiment Construction

[0030] As shown in Fig. 1, the present invention is externally provided with a wireless camera, and a wireless receiving part is set up inside the television set, which is used to convert monitoring signals into audio and video signals, and sends them to the input end of the selector switch of the television set; and the selector switch is connected to the The channel between the camera signal receiving circuit and the corresponding signal channel in the TV is controlled by the MCU, and is used to select the monitoring signal from the camera or the sub-picture TV signal.

[0031] In this solution, the output of the wireless receiving end is a full TV signal (CVBS) and an audio signal transmitted by a transmitting end. The signal transmission of the wired camera is directly connected through wires, similar to the AV input terminal.

[0032] Wireless cameras can transmit camera signals from one place to another through wireless methods. Its carrier frequency is 2.4G, which is a ...

Thereby, user can enjoy program and monitor outer synchronously to increase life security.

Description

technical field [0001] The invention relates to a new application of television, in particular to the application of using television to realize safety monitoring of office or home. Background technique [0002] The technology of inserting a small picture into the TV picture is called Picture in Picture (Picture in Picture) technology. The picture-in-picture technology has been applied since the 1970s. It has developed rapidly and is very mature. It adopts microcomputer control technology, digital signal processing technology and storage technology. However, so far, TV manufacturers have always provided the picture-in-picture as a window of candidate channels to users, and have not yet seen other applications. [0003] At the same time, the current security monitoring method basically adopts video intercom technology. Regardless of the office environment in the city or the home environment, most of them are equipped with a video intercom system. The video intercom system is...
