Problems solved by technology

[0020] Since the basic description information of ESG needs to be received on the control channel of mobile multimedia broadcasting, while ESG data information is transmitted on the service logic channel, and programs such as TV are transmitted on another service transmission channel, according to the above receiving method, the terminal device receives ESG When receiving data, it is necessary to switch frequently between different receiving channels. Switching will consume time, which will affect the receiving speed of terminal equipment and the normal viewing of users. If you want to avoid the impact of switching, it is usually necessary for the terminal to be able to receive two or more channels at the same time. The data of the channel will increase the processing capacity requirements of the terminal and increase the cost of the terminal

Embodiment Construction

[0046] In order to solve the disadvantages of the traditional technical solutions, the present invention further elaborates a method and device for receiving ESG data of the electronic service guide described in the present invention through the following specific examples. limit.

[0047] In order to reduce switching between channels, a control information table is pre-built inside the mobile multimedia terminal, including two entries: ESG control information entry and multimedia control information entry; where,

[0048] ESG control information table items include at least: ESG service identifier, ESG multiplexing frame identifier and physical broadcast channel parameters (modulation parameters, coding parameters, interleaving mode, etc.); Use frame identification and physical broadcast channel parameters;

[0049] The multimedia control information table item at least includes: several multimedia service identifiers, multimedia multiplexing frame identifiers and physical b...

Abstract

The invention provides a receiving method of the electronical operation guide EGS data and a device thereof, comprising: preserving the ESG operation ID and the corresponding multiplexing frame ID and the physical broadcast channel parameter in advance by a receiving end, according to the EGS operation ID, arranging and using an operation logic channel to receive the ESG data according to the ESG operation ID, the multiplexing frame ID and the physical broadcast channel parameter. The invention avoids the frequent switch of the receiving channel, thereby accelerating the receiving speed, with the ability of receiving two channels at the same time with the terminals, which ensures the fast acquisition of the related multimedia operation according to ESG for the user.

Description

technical field [0001] The invention relates to the reception of service data of mobile multimedia broadcasting, in particular to a method and device for receiving electronic service guide data. Background technique [0002] When mobile multimedia broadcasting network users use mobile multimedia broadcasting services, they can navigate through Electronic Service Guide (ESG, Electronic Service Guide) or Electronic Program Guide (EPG, Electronic Program Guide) to understand the relevant information of mobile multimedia broadcasting services (including service name, broadcasting information, etc.) Time, content summary and price, etc.), and realize fast retrieval, preview and access to the business. ESG provides a good navigation mechanism for users to watch TV programs and enjoy information services, so that users can easily and quickly find the programs they care about and view the additional information of the programs. In the CMMB mobile multimedia broadcasting system, the...
