Transmission method for data information of electronic service directory

Abstract

This invention discloses a transmission method for data information of electronic service directory including: dividing data information into one or several kinds of service information, arranging information, content information and operation parameter information by a data kind identification field, segmenting the sorted data information in terms of blocks by a data block identification field, segmenting the data block into several sections by a section sequence number field, and the data sections are corresponding to the data units of complex sub-frames, which are transmitted in the service logic channels of an 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 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. The mobile multimedia broadcasting system can transmit more TV channels within a limited bandwidth, increasing the number of TV channels transmitted, thus enabling users to enjoy many different TV channel programs very conveniently. [0003] However, due to the increase in the number of TV channels, it is difficult for users to easily find favorite TV programs or programs to be played from the numerous TV channel programs. Therefore, there is a need for a gui...

Problems solved by technology

[0007] The ESG data information in the prior art has the following problems. First, the ESG data information is too large. Broadcasting and sending these ESG data information consumes 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.
