Problems solved by technology

[0004] Due to the limitations of its hardware capabilities, the previous embedded decoder devices can only decode a limited number of channels of video
If you want to decode multi-channel video, you can only increase the number of devices, but at the same time increase the number of devices and require more device IPs, which adds difficulty and unnecessary overhead to the site layout; in order to decode multi-channel video, a lot of decoding is added Multiple devices are not convenient for users to manage, which virtually increases the complexity of user operations

Abstract

The invention provides network cascading architecture and cascading method employed on an embedded decoder. The network cascading architecture comprises client modules, proxy modules, a master group, stream modules and decoder modules. The master group is in signal connection with the proxy modules and the stream modules. The proxy modules are connected with the client modules. The stream modules are connected with the decoder modules. The network cascading architecture and cascading method are easy to expand and the network bandwidth and decoding capability are in fold increase. A user can carries out configuration according to onsite practical demands. Unnecessary waste is avoided. Costs of a product are indirectly reduced.

Description

technical field [0001] The invention belongs to the technical field of monitoring, and in particular relates to a network cascading architecture and a cascading method used on an embedded decoder. Background technique [0002] A decoder is a device that decodes encoded audio and video data and displays it on a monitor through an output interface such as BNC / VGA / HDMI / DVI. [0003] With the rapid development of surveillance technology, how to browse more and higher-definition videos on a limited TV wall has become an urgent need. Embedded devices cannot infinitely increase network transmission bandwidth and decoding capabilities due to their hardware limitations. How to access more network videos and how to achieve seamless expansion has become a topic that we need to solve urgently. [0004] The previous embedded decoder devices can only decode a limited number of channels of video due to the limitation of its hardware capabilities. If you want to decode multi-channel video...
