Abstract

The invention discloses a multiple description coded distributed media stream distribution system and a method, and the multiple description coded distributed media stream distribution system comprises a storage subsystem, a storage scheduling subsystem, a multiple description coding subsystem, a distribution subsystem and a distribution scheduling subsystem, wherein the storage scheduling subsystem is used for selecting N first distributed storage units from a plurality of distributed storage units; the multiple description coding subsystem is used for carrying out multiple description coding on an original video, forming N multiple description coded code streams and respectively sending the N multiple description coded code streams to the N first distributed storage units for storing; the distribution subsystem is connected with the storage subsystem and comprises a plurality of distributed distribution units; and the distribution scheduling subsystem is used for selecting M first distributed distribution units in the distributed distribution units connected with the first distributed storage units according to a client request and notifying a multiple description decoding subsystem arranged at a client. The invention can improve the reliability of the system.

Description

technical field [0001] The invention relates to a multimedia distributed network real-time video system, including storage and playback systems in the fields of mobile streaming media, IPTV live broadcast, network video monitoring and the like. Background technique [0002] With the advancement of technologies such as FTTH ((Fiber To The Home, Fiber To The Home), EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network), fixed network broadband access bandwidth provides objective conditions for services such as IPTV and video surveillance. . [0003] The development of wireless communication technology has also broken the bandwidth bottleneck limitation for multimedia wireless applications, especially after the 3G network is upgraded to the HSPA (High Speed ​​Packet Access) stage, the transmission bandwidth of the 3G network can reach several M, which can Fully meet the requirements of high-definition video in some special scenes. [0004] At present, China...
