Distributed audio and video task management and distribution system and implementation method

Abstract

The invention discloses a distributed audio and video task management and distribution system and an implementation method, the system comprises a first-level server and a plurality of second-level servers, all the second-level servers are connected with the first-level server, each of the first-level server and the second-level servers comprises a business service module and a relay service module, the business service module of the first-level server is in communication connection with the relay service modules of all the second-level servers under the first-level server, the relay service module in the same server is in communication connection with the business service module, and the relay service modules are used for managing peripheral devices and receiving and transmitting audios and videos from the peripheral devices, and the business service module is used for forwarding the audio and the video to the relay service module in the target server. According to the invention, the split use and multi-level management of hardware resources are realized, and the separation of upper-layer business logic and bottom-layer hardware resources is realized, so that the business module does not need to carry out customized processing on bottom-layer hardware.

Description

technical field [0001] The invention relates to the technical field of audio and video broadcasting, in particular to a distributed audio and video task management and distribution system and an implementation method. Background technique [0002] When currently broadcasting audio and video tasks, such as when rail transit, enterprises and institutions broadcast audio and video tasks, the broadcast system usually adopts centralized management, that is, there is only one level server, and all audio and video are controlled by the central server (i.e. a central server). level server) for processing and sending, and the corresponding device resources are also managed by the central server. With the broadcast system and method of this structure, the central server bears all the load, and the concurrency supported by the system will be limited by the hardware load capacity of the central server itself, which is prone to bottleneck problems. When it is necessary to increase the b...

AI Technical Summary

Problems solved by technology

In the broadcast system under this structure, its load is divided into various subsystems. Although the concurrency capability is solved, because the subsystems are independent of each other, only basic information synchronization can be performed, and it is difficult to perform cross-system Operation, realizing cross-system audio and video management and distribution
