MEDIA TYPE PROCESSING AND MEDIA PLAYING METHOD AND DEVICE IN IPTV SYSTEM

摘要

A media type processing method and apparatus, a media playing method and an EPG subsystem in an IPTV system are provided. The processing method and the media playing method comprise: defining a media type set; an SMS subsystem mapping all media types supported by the programs or the channels into the media type set, and issuing to an EPG subsystem; mapping the media types supported by a terminal as the media type set; after the authentication is passed, the SMS subsystem returning the media type set supported by the terminal to the EPG subsystem; and after the EPG subsystem receives a media playing request from the terminal, judging whether the media type set supported by the terminal is matched with the media type set supported by the programs or channels, and if being matched, then acquiring information about the playable physical program from a database and issuing to the terminal for playing. By the method and apparatus provided in the present invention, the media types are concluded to form the media type set, so as to meet continuously increasing demand of a multi-screen service of an IPTV system to the media diversity.
