Abstract

The invention discloses a method for providing network television service information. The method is as follows: when the service finding information changes, an electric program list EPG server informs a user terminal by an EPG finding server; according to the message of the EPG finding server, the user terminal updates the service finding information together with the EPG server; correspondingly, the invention provides a network television service system, the system comprises an EPG server used to provide the service finding information, an EPG finding server used to provide the EPG findinginformation and send the message to a user terminal and the user terminal used to update the service finding information together with the EPG server according to the message of the EPG finding server, wherein when the service finding information changes, the EPG finding server informs the user terminal, and updates the service finding information together with the user terminal. The technical proposal of the invention can improve the updating mechanism of the service information in the network television service.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for providing network television service information and a network television service system. Background technique [0002] Internet TV IPTV (IP Television) refers to the use of various electronic devices such as computers, TV sets, and mobile phones as receiving terminals to transmit TV, video, text, graphics, and data on the IP network, and to provide service quality / service experience (QoS / QoE) guaranteed, secure, interactive and reliable managed multimedia services.
