Problems solved by technology

[0003] However, the existing IPTV service has the problem of insufficient flexibility, as follows:
[0004] The carousel channel can only play fixed default programs in a loop, which lacks flexibility;
[0005] The live channel cannot make a play plan, but can only play reserved content, which also lacks flexibility

Abstract

The invention provides an IPTV service implementation method, a service node and an IPTV system. The service node comprises a service processing unit and at least one streaming media processing unit, wherein the service processing unit is used for transmitting a first switching indication message to the streaming media processing unit when the current time is the same as a starting time in a playing plan; the first switching indication message is used for indicating a target playing object which is in the playing plan and corresponding to the starting time; and the streaming media processing unit is used for switching to the corresponding media content for playing the target playing object in a target channel when receiving the first switching indication message. The invention enhances the flexibility of the IPTV services.

Description

technical field [0001] The invention relates to the technical field of IPTV, in particular to a method for realizing IPTV services, a service node and an IPTV system. Background technique [0002] At present, IPTV technology has become a popular technology, IPTV services are constantly expanding, and IPTV solutions are emerging in an endless stream. As far as basic services are concerned, there are mainly two types, one is channel services where all users see the same content at the same time, such as carousel services, and the other is on-demand services where each user is free to fast forward, rewind, and positionally play . On-demand services mainly include VOD (Video On Demand) on-demand, TVOD (Video On Demand) on-demand, and time-shifted TV TSTV on-demand by users on time-shifting channels. [0003] However, the existing IPTV service has the problem of insufficient flexibility, as follows: [0004] The carousel channel can only play fixed default programs in a loop, ...
