Embodiment Construction

[0055] In view of the problem that the display device resources in the existing video surveillance system cannot be fully utilized, by increasing the input resolution of the large-screen splitter, that is, by increasing the resolution of the front-end encoding, it will bring a quadratic computing workload, which requires Stronger hardware processing capabilities, but the current DSP (Digital Signal Processor, digital signal processor) processing technology cannot perform encoding higher than 1080P, so it is not feasible for the time being. The embodiment of the present invention divides the data collected by the CCD (Charge Coupled Device, electric coupler) of the IPC into a plurality of regions by improving the processing of the DSP encoding end, the arrangement mode of the region division and the split-screen mode of the large screen same. The data in each area is encoded separately and then sent to an independent decoder for decoding and then sent to the corresponding displ...

Abstract

The invention discloses a video data processing method, device and system, applied to an audio / video monitoring system. In the audio / video monitoring system, decoders are connected with corresponding displayers and are used for decoding video data and sending the decoded video data to the corresponding displayers for display; after a monitoring client initiates a video data access request to a server, an internet protocol camera (IPC) receives the video data access request sent by the server, wherein the video data access request carries split screen mode information and corresponding relation information between split screen regions and the decoders; the IPC blocks collected video data according to the split screen mode information and respectively encodes the blocked data so as to encoded data of each split screen region; and according to respective decoders corresponding to the split screen regions, the IPC respectively sends the encoded data of the split screen regions to the corresponding decoders to be decoded. According to the invention, the problem of display equipment resource waste caused by a data encoding mechanism in the prior art is solved.

Description

technical field [0001] The invention relates to video monitoring technology in the field of communication, in particular to a video data processing method applied to an audio and video monitoring system, a device and a system thereof. Background technique [0002] With the development of audio and video codec technology and network storage technology, the image data of the camera is digitized, and transmitted and stored on the Internet network to form a digital video surveillance technology. [0003] Video surveillance technology is a key technology in urban security systems. The current video monitoring system has formed an integrated monitoring method of "analog monitoring + network monitoring storage + comprehensive management". The camera is an indispensable part of the surveillance system, and the video image quality is the key to the surveillance system. After several years of development, the camera technology has developed rapidly, and the pixels of the camera are ...
