Embodiment Construction

[0047] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0048] Such as figure 1 As shown, this embodiment provides a multimedia service system that can realize time-shifted playback of IPTV multicast channels, including a channel multicast source (MS, Muticast Source), and a time-shift redirection server (TSRS, Time-Shift Redirect Server) , time-shift write server (TSWS, Time-Shift WriteServer), time-shift storage server (TSSS, Time-Shift Storage Server), multiple streaming media servers (SS, Stream Server) and user terminal equipment (UE, User Equipment), In this embodiment, the user terminal device takes a user set-top box (STB, Set Top Box) as an example. The channel multicast source sends the code stream to the time-shift writing server and user equipment in a multicast manner, and the time-shift writing server writes the time-shift code stream to the time-shift storage server, and the...

Abstract

The invention relates to a method for storing and acquiring media time-shifting code stream and a multimedia service system. The system comprises a media source, a user terminal device, a time-shifting write server, a time-shifting storage server, a time-shifting redirection server and a plurality of stream media servers; the time-shifting write server receives the media code stream sent by the media source and writes the media code stream into the time-shifting storage server; when the user terminal device acquires time-shifting code stream of media content, the user terminal device requeststhe time-shifting redirection server to select a stream media server for the user terminal device, and then the selected stream media server establishes media control session of time-shifting serviceand requests the time-shifting code stream of the media content to the stream media server; and the stream media server acquires the time-shifting code stream of the media content from the time-shifting storage server and sends the time-shifting code stream to the user terminal device, and the user terminal device receives the time-shifting code stream. The method and the system can save a storage space for storing the time-shifting code stream, and support the concurrent access of the large-scale user terminal device.

Description

technical field [0001] The invention relates to the field of multimedia services in telecommunication networks, in particular to a method for storing and acquiring media time-shifted code streams and a multimedia service system. Background technique [0002] The improvement of network bandwidth and the development of telecommunication network technology have made it possible to carry out value-added services based on media content on telecommunication networks. Streaming media technology provides a way to transmit media content such as video, audio, and pictures in the network, so it has been widely used in multimedia service systems, especially IPTV multimedia services. At the same time, with the development of telecommunication network technology, it has gradually become a trend to carry out multimedia services in the telecommunication network, such as IPTV network television, video surveillance, mobile streaming media and other multimedia services. [0003] The basic for...
