Broadcast media sharing method and node subsystem, and streaming media server

Abstract

The invention discloses a broadcast media sharing method in an Internet protocol television (IPTV) broadcast service. The method comprises the following steps: when a streaming media server receives a broadcast media service request sent by a client, obtaining the address of a channel broadcast source, included in the broadcast media service request; and obtaining a broadcast code stream corresponding to the address from the streaming media server or from a media exchange device, and sending the broadcast code stream to the client. The invention also simultaneously discloses a streaming media server and a broadcast media sharing node subsystem. By applying the technical scheme provided by the invention, the problems of incapability of providing broadcast services timely due to imbalanced load of each streaming media server in the node subsystem and the like are solved, and the IPTV broadcast service interaction speed and the user service experience are improved.

Problems solved by technology

However, for the same channel program, if each streaming media server receives one live code stream from the encoder, more encoders are required, resulting in high cost; and, if there are too many encoders, the The management of channel business will become complicated, and the bandwidth of the occupied network equipment will also increase, which will waste bandwidth resources; It will lead to a serious load imbalance between streaming media servers, which in turn will cause the streaming media server where the hot channel is located to be unable to provide users with live broadcast services in time due to insufficient capacity, affecting the user's business experience
