Distributed IP (Internet Protocol) video decoder synchronous stitching and on-wall method and system

Abstract

The invention provides a distributed video decoding system and a synchronous stitching and on-wall method thereof. The distributed video decoding system comprises a decoder group consisting of a plurality of discrete IP (Internet Protocol) video decoders. According to the method, synchronous stitching and on-wall of a plurality of discrete IP video decoders are realized by using a video stitching and synchronizing mechanism and a decoding control mechanism. According to the method and the system, parts of IP images are selected through a plurality of decoders respectively to be directly decoded and put on a wall without being limited to a centralized stitching controller or purchasing an expensive stitching management hardware platform, so that the cost and the complexity are effectively reduced, and meanwhile, a better effect is achieved; the synchronizing mechanism of the distributed method is implemented on the basis of software, the hardware dependency is extremely low, and the system can be very conveniently transplanted to different hardware platforms.

Description

Technical field: [0001] The invention relates to the field of security monitoring, in particular to a system and a method for decoding and synchronizing an IP video decoder on a splicing wall. Background technique: [0002] The practice of splicing traditional video sources (computers, decoders, etc.) on the wall is realized by splicing controllers. This type of splicing controller is generally implemented by full hardware and supports multiple video input modes, such as HDMI, VGA, BNC, etc. When the IP network video is to be spliced ​​on the wall through this type of splicing controller, it must first be converted to the input format supported by the splicing controller with a decoder, such as HDMI, and then unified on the splicing wall through the splicing controller. This method can be called a centralized processing method on hardware. First of all, this method is highly dependent on hardware, which is very inconvenient for transplantation. Every improvement and fine-t...

Problems solved by technology

First of all, this method is highly dependent on hardware, which is very inconvenient for transplantation. Every improvement and fine-tuning is accompanied by hardware upgrades; secondly, this centralized processing method is very convenient and reliable, but requires customers to purchase special splicing. It is not a small expense to control the equipment. In addition, the steps of combining such a system are relatively cumbersome, requiring both labor costs and expensive hardware costs.
