Digital user line cut-in multiplexer, stream medium data transmission system and method

Abstract

The invention relates to a digital user line access multiplexer that includes main control module, device managing interface module, media server. It also relates to a stream media transferring system that includes plural stream media servers, plural digital user line accessing multiplexer, and plural stream media access receiving terminal. The invention also relates to a stream media transferring method that includes the following process: digital user line access to the stream media data that is sent by stream media server by the multiplexer accessing to main network; and the digital user line accessing to multiplexer to take process to the data and send to the receiving terminal. The invention realizes the monitoring of the stream media, and the transferring system and method. It realizes living broadcast through simple structure.

Description

Technical field [0001] The invention relates to a digital subscriber line access multiplexer and a streaming media data transmission system and method, in particular to a digital subscriber line access multiplexer and streaming media data transmission system and method that can provide streaming media data processing. Background technique [0002] Streaming media technology is a technology for transmitting and implementing multimedia. The receiving terminal can play it after obtaining part of the media content. It does not need to receive all media data completely, but only needs to continue to obtain media data through the network during the playback process. To continue playing. Asymmetrical Digital Subscriber Line (ADSL) is a technology that can provide broadband data services through ordinary telephone lines. [0003] With the development of the times, a service based on IP broadband network for multimedia transmission-IPTV, also known as "broadband TV", has emerged. IPTV ser...

Problems solved by technology

[0004] The existing DSLAM cannot monitor streaming media data. The existing streaming media transmission system is composed of multiple streaming media servers into a cluster, which is placed in the data center to provide services for users in different network topologies. The existing networking method The disadvantage is that because the streaming media server is located in the data center, all network devices in the entire network must support the multicast function, so the network structure is relatively complicated, and there must be a large number of streaming media servers in the network center, and the pressure of data processing is very high. Caused the existing streaming media transmission method to be more loaded down with trivial details

Moreover, in the existing streaming media transmission system and transmission method, due to the centralized deployment of servers, user access may need to be extended to multi-pole networks, the quality of service cannot be guaranteed, and the video-on-demand mode is the main mode, and the live mode is supplemented. Therefore, the structure is very Complicated, it is impossible to implement live broadcast easily, and there is no networking method that is particularly suitable for live broadcast
