All-standard video automatic identification system

Abstract

The invention discloses an all-standard video automatic identification system, which specifically comprises the following steps of: 1, a monitor is opened by using a high-tech chip to supply power toa camera of any standard; 2, the camera generates a real-time video stream and transmits the real-time video stream to a video decoding chip; 3, the video decoding chip decodes the video stream and directly transmits the decoded video stream to the high-tech chip; 4, the system of the high-tech chip is judged through adoption of a self-made algorithm; and 5, the image is quickly displayed on the LCD display screen. The all-standard video automatic identification system has the advantages that: 1, the video identification system does not need to be switched manually; 2, an all-standard video isautomatically detected in real time; 3, the identification display speed is shortened, so that the video is more stable, accurate and safer; 4, the system is compatible with most cameras on the market; and 5, the monitoring camera can be replaced at any time when the indoor unit works.

Description

technical field [0001] The invention relates to the technical field of recognition systems, in particular to a full-standard video automatic recognition system. Background technique [0002] 1. In the traditional doorbell industry, an indoor unit can only be connected to one type of camera. If you want to achieve full-standard video display, it is generally achieved by manually modifying the video receiving standard of the indoor unit (see the attached manual for details). Figure 4 ); [0003] 2. Relying on the external video decoding chip, when the indoor unit is turned on, the 14 camera formats can be identified in turn by elimination method (see the attached manual for details). Figure 5 ); [0004] The disadvantages and pain points of the first method mainly include the following aspects: an indoor unit can only recognize one video system at a time, when the video system does not match and the system is unknown, it needs to manually switch the video system up to 14 t...

Problems solved by technology

[0004] The disadvantages and pain points of the first method mainly include the following aspects: an indoor unit can only recognize one video system at a time, when the video system does not match and the system is unknown, it needs to manually switch the video system up to 14 times, and it is difficult for users to distinguish Various camera formats, poor practicality

The disadvantages and pain points of the second method mainly include the following aspects: when the indoor unit is turned on, the elimination method is used to identify the video system, which leads to a longer start-up time and different lengths of time; when the indoor unit is working, the camera system is switched, and it will no longer be recognized. video format
