Embodiment Construction

[0028] The first embodiment provided by the present invention is a method for providing IPTV services for different types of terminals. Before implementing the first embodiment, it is necessary to store multiple media files for each program in the media server, and the media files correspond to the attribute information of the terminal. It is also necessary to store metadata (including URLs) and the like of multiple media files corresponding to each program in the CMS. Each terminal is also required to collect various context information of itself, and the context information mainly includes terminal attribute information such as terminal type, network access type, resolution, and supported encoding format. The process is shown in Figure 1, including the following processes:

[0029] Step S101, when the terminal needs a media service, it sends an HTTP (Hypetext Tranfer Protocol) request message to an EPG (Electric Program Guide, Electronic Program Guide) server, which carries...

Abstract

The EPG server obtains linked message related to the terminal statistic attribute message from CMS the media document and generates the related link path according to the linked message. The terminal asks the media server for the corresponding media document according to the link path and obtains the corresponding media data. According to the attribute messages such as net access type, resolution and coding format supported by different terminals, this invention sends appropriate media data to support the match between different types of terminals. The document coding method is simple.

Description

technical field [0001] The present invention relates to the communication field, in particular to IPTV (IP Television, IP-based television service) provision technology. Background technique [0002] IPTV is based on IP technology. Through a manageable network, it provides users with interactive services based on audio, video and streaming services, including basic services such as live TV, video on demand, and time-shifted TV. Triple play (triple play) services including communication, data, and video carried out on the Internet. [0003] With the continuous demand of people, IPTV business has developed from the original single fixed network and fixed terminal to mobile network and mobile terminal, which requires each operator to meet the needs of both fixed network users and mobile users when building an IPTV service platform. Therefore, the IPTV media distribution system supports multiple terminals at the same time, including PC (Personal Computer, personal computer), ST...
