Multimedia code stream transmission method and system and management server

Abstract

The invention discloses a multimedia code stream transmission method which comprises the following steps: a management server receives and saves a network service quality reported by a designated media server in every retransmission route; and the management server selects a retransmission route from a coder to a decoding terminal according to the network service quality reported by the designated media server in every transmission route, when receiving a multimedia request from the decoding terminal, and notifies the coder to transmit multimedia code stream to the decoding terminal via the selected retransmission route. The invention also discloses a multimedia code stream transmission system and a management server. The technical proposal improves the network utilization rate and the experience of a user.

Description

A multimedia code stream transmission method and system and management server technical field The invention relates to the technical field of multimedia transmission, in particular to a multimedia code stream transmission method and system and a management server. Background technique In the networking structure of a large-scale video surveillance system, the multimedia code stream from the encoder to the decoding terminal usually needs to be forwarded by a media server (MS, MediaServer). Here, the multimedia code stream from the encoder to the decoding terminal is an audio code stream, a video code stream or an audio and video code stream. FIG. 1 is a schematic diagram of a network of an existing video surveillance system. As shown in FIG. 1 , an encoder in a video surveillance system is generally a digital video recorder (DVR, Digital Video Recorder) or a network video server (DVS, Digital Video Server). DVS is a special equipment for encoding audio and video data and...

However, in the prior art, the scheme of judging the convergence ratio from the video encoder to a specific MS and the QoS status of the network in advance, and fixedly configuring the binding relationship between the encoder and the MS according to the judgment result, in actual operation, The actual convergence and network QoS status may be inconsistent with the pre-judged situation, which will eventually reduce network utilization and user experience
