Transmission method for electronic service guide dat information based on XML

Abstract

This invention discloses a transmission method for data information of electronic service instructions including: dividing data information into one or many kinds of service information, layout information, content information and service parameter information according to their kinds to identify the fields with data kind, in which, said data information is based on the XML format, the sorted data information is segmented in blocks and differentiated by data blocks, the data blocks are segmented into several sections by section sequence number fields, the data units of the data section correspond to the multiplex subframes, then the data information is kept into a data unit of multiplex subframes to be transmitted in a logic channel of electronic service directory.

Description

technical field [0001] The invention relates to the data information of the electronic service guide in the mobile multimedia broadcasting system, in particular to the composition and transmission of the data information of the electronic service guide in the mobile multimedia broadcasting system based on XML and its realization method. Background technique [0002] With the development of digital broadcasting technology, it has made it possible to use digital satellite broadcasting technology to provide services such as mobile TV, and the service of mobile TV is also increasing constantly, making the service of mobile TV more and more abundant.

Problems solved by technology

[0006] The ESG data information in the prior art has the following problems. First, the ESG data information is too large, and broadcasting and sending these ESG data information needs to consume too much wireless bandwidth, and the terminal receives these data. It also consumes a lot of resources; second, the ESG data information The design of data information is not reasonable. If packet loss, transmission interruption, and limited storage space of terminal equipment are considered during the transmission process, the ESG data information received by the terminal equipment will be unavailable.

For example, the terminal receives the content information of the ESG data information, but loses the information of the playing time of this content information, so that the user cannot know the preview information of the content of the program, etc.
