An on-demand encoding system and method for analog video signals

Abstract

The invention discloses an on-demand encoding system and an on-demand encoding method of an analogue video signal. The method comprises the following steps: a streaming media server transmits an encoding request signal to a dispatch server after receiving an on-demand request signal of a video play terminal to video data; and the dispatch server selects a free encoding channel from a video encoder cluster after receiving the encoding request signal, transmits an encoding channel switching signal to a video matrix switcher, and switches an input source of the free encoding channel into an analogue video source for outputting the video data through the video matrix switcher, and thus, the video encoder on which the free encoding channel is positioned can encode the video data broadcasted by the video play terminal and does not encode the video data output from other video sources. According to the on-demand encoding method, the on-demand encoding of the analogue video signal is achieved; the quantity of the video encoders distributed by the monitoring system is reduced, and the construction cost and the operating cost of the system are reduced.

Description

technical field [0001] The invention relates to the field of video communication, in particular to an on-demand encoding system and method for analog video signals. Background technique [0002] Although the digital video technology develops rapidly, it is still necessary to use a large number of analog cameras and other devices that output analog video signals in many fields such as security. With the development of the mobile Internet, people hope that they can easily watch various surveillance videos on mobile terminals such as mobile phones and PDAs, so as to realize mobile office, but it is difficult to directly output analog video signals to mobile terminals. , It is usually necessary to encode the analog video signal into a digital video signal in the format of MPEG-4, H.264, etc., and then transmit it to the mobile terminal through a wireless network. Among them, the full name of MPEG is Moving Pictures Experts Group, that is, the Moving Pictures Experts Group. This...

Problems solved by technology

However, the number of monitoring points in a security monitoring network is very large, usually hundreds or even thousands. To encode the analog video signals of all monitoring points into digital video signals requires the deployment of hundreds or even more video encoders. The amount of money required to purchase equipment and the power consumption of the equipment during operation are huge
