Abstract

A transmission method for movable multimedia broadcast business parameter information comprises the steps: a front end seals the parameter information of a target business as a specific ESG business frame and seals the business mark a marking the ESG business frame, a timeslot number thereof, the business mark and a timeslot number thereof of a corresponding target business in a control frame; respectively modulates the control frame and the business frame on the control channel and the business channel of the network to transmit periodically. The terminal is tuned on the control channel to receive the unsealed business mark a and the timeslot number, switches to the corresponding timeslot receiving unsealing ESG data information, sets the parameters of a video/audio decoder according to the parameter information of the resolved target business; switches to the business data in each corresponding timeslot receiving unsealing business frame to play according to the business mark and the timeslot thereof of the resolved target business. The invention saves the system resources, enhances the flexibility and reliability of deployment and simultaneously reduces the requirement of a user terminal as well.

Description

technical field [0001] The invention relates to information transmission technology in a mobile multimedia broadcasting system, in particular to a method and device for transmitting service parameter information in a mobile multimedia broadcasting system. Background technique [0002] In the mobile multimedia broadcasting (such as China Mobile Multimedia Broadcasting CMMB, China MobileMultimedia Broadcasting) system, each mobile multimedia broadcasting service has its own parameter information, and the terminal must obtain the relevant parameter information of the target service in order to correctly decode the target service show. [0003] Electronic Service Guide (ESG, Electronic Service Guide) is a navigation system for mobile multimedia broadcasting services, which is mainly used to describe relevant information of all multimedia broadcasting services provided to users, so as to facilitate terminal users to quickly retrieve and access multimedia broadcasting services. ...
