Embodiment Construction

[0047]The present invention provides a multimedia service creation method and system to provide users with on-demand and live broadcast services by multiple nodes in a multimedia system. The multimedia control center server implements notification of the first node (also referred to as the central node) and The second node (also called a regional node, in the multimedia service creation system, there can be multiple regional nodes) creates the same type of service (for example, creates the same type of live broadcast or on-demand multimedia service), especially through the center The RTSP signaling link established between the node and the regional node is used to negotiate multimedia services, so as to avoid dependence on the live broadcast source when creating the live broadcast service, and when creating the on-demand service, the multimedia service content required by the user can be Distribute from the central node to the regional nodes through RTSP.

Abstract

The invention relates to a multimedia service creating method, which comprising the following steps: establishing signaling link between a first node and a second node; carrying out multimedia negotiation with the second node and the first node by the signaling link; establishing a media channel used for transmitting the contents of the multimedia service so as to finish the establishment of the multimedia service on the second node. The invention also relates to a multimedia service establishing system; therefore, by the invention, the signaling link is established between the first node and the second node; the signaling link is used for the multimedia negation, establishing the multimedia channel and finishing the multimedia service establishment on the second node, thus realizing the unify establishment of the multimedia service and simplifying the scheduling of the multimedia content.

Description

Technical field [0001] The present invention relates to the field of multimedia network television, in particular to a multimedia service creation method and system using RealTime Streaming Protocol (RTSP). Background technique [0002] In the network TV service system, it is necessary to provide users with multiple multimedia services such as live broadcast and on-demand at multiple nodes. Therefore, the problem of creating multimedia services of the same nature on multiple nodes is involved. For live broadcast services, it is necessary to achieve simultaneous access to the code stream at multiple nodes; for on-demand services, there is storage of a multimedia content between multiple nodes. [0003] At present, the live broadcast service between different nodes can be realized through the whole network multicast, that is, the live broadcast service is created at the central node, and the media code stream is sent to the multicast router. Each regional node can join the multicas...
