Audio and video decoding system and decoding method thereof

Abstract

The invention provides an audio and video decoding system and a decoding method thereof. The system comprises at least one communication module which is used for data exchange between the audio and video decoding system and front-end equipment; at least one decoding module which is electrically connected with the communication module and used for acquiring the required audio and video data from the front-end equipment via the communication module and decoding the audio and video data; at least one interface module which is electrically connected with the decoding module and used for providing multiple audio and video output interfaces and outputting the audio and video data decoded by the decoding module to display equipment; a control module which is electrically connected with the communication module, the decoding module and the interface module and used for dynamically controlling loads of all the modules in a balancing way according to the existing loads of all the current modules in the audio and video decoding system and the loads capable of being borne by the system; and a power supply module which is used for supplying power to the audio and video decoding system.

Description

technical field [0001] The invention relates to the field of real-time audio and video display of an intelligent security monitoring system, in particular to a structure and a design method of a distributed, configurable and expandable audio and video decoding system. Background technique [0002] With the rapid development of security surveillance systems, the market demand for surveillance cameras has increased sharply, and the requirements for the clarity and real-time performance of surveillance images displayed by background decoding are getting higher and higher. At present, the audio and video decoding functions of most platforms on the market are realized through centralized architecture servers and software methods, which brings several problems: First, the software method to realize audio and video decoding functions is limited by the centralized architecture Second, the scalability of servers with a centralized architecture is not strong. If the scale of the front...

Problems solved by technology

At present, the audio and video decoding functions of most platforms on the market are realized through centralized architecture servers and software methods, which brings several problems: First, the software method to realize audio and video decoding functions is limited by the centralized architecture Second, the scalability of servers with a centralized architecture is not strong. If the scale of the front-end equipment expands, the cost of upgrading the back-end server will increase significantly; third, the market demand for multi-screen display of surveillance images is increasing. Strong, the expansion of the server display interface of the centralized architecture is limited by the space of the server carrier
