Technical field

The present invention relates to the field of mobile multimedia broadcasting, and in particular to a transmission system, method and apparatus for electronic service guide information.

Background technique

Mobile multimedia broadcasting services (also known as mobile TV) have various implementation technologies, such as Multimedia Broadcast Multicast Service (MBMS) based on mobile communication networks, and Broadcast and Multicast Service (BCMCS). , streaming media technology, also based on broadcast networks (terrestrial digital broadcasting, satellite digital broadcasting) technology, such as digital video broadcast handheld reception (DVB-H, Digital Video Broadcast Handheld) in Europe, US media single forward link ( MediaFLO, Media Forward Link Only), Japan's Integrated Services Digital Broadcasting-Terrestrial (ISDB-T, Integrated Service Digital Broadcasting-Terrestrial) and China's China Mobile Multimedia Broadcast (CMMB), and application layer Assistive technology. The mobile multimedia broadcast service based on broadcast network has been widely used due to its high spectrum utilization, large capacity, relatively low construction cost and wide audience.

Mobile multimedia broadcast network users use the Electronic Service Guide (ESG) or EPG (Electronic Program Guide) navigation to learn about mobile multimedia broadcast services (including service names, Play time, content synopsis, price, etc., and enable fast retrieval, preview and access to the business. ESG provides a good navigation mechanism for users to watch TV programs and enjoy information services, enabling users to quickly and easily find programs they care about and view additional information about the programs. In mobile multimedia broadcasting systems, electronic business guides are mainly composed of the following information or data:

(1) Basic description information for describing the version of the electronic service guide and the information transmitted by the ESG, that is, the data index information of the electronic program guide;

(2) ESG data information, used as the main data describing the electronic business guide, that is, used to describe Information about the business, content, and program play previews and service access parameters;

(3) Program prompt information, used to predict the information of the current channel being played and the name of the program to be played in time is long.

The general mobile multimedia broadcast network works within a range of frequencies. For example, the China Mobile Multimedia Broadcasting System can operate in the frequency range of 30 MHz to 3000 MHz. According to the mobile multimedia broadcast channel standard, the mobile multimedia channel bandwidth can be 8 MHz or 2 MHz. Therefore, the frequency point must be in the frequency range, and the bandwidth determines the frequency point; for example, the 14-frequency point of the CMMB is 482 MHz, the channel bandwidth is 8 MHz, and the working range of the 14-frequency point is 478 MHz to 486 MHz), thus the mobile multimedia broadcast network It can operate at one or more frequency points, and the mobile multimedia broadcast service signal is transmitted at multiple frequency points. Therefore, when the mobile multimedia broadcast receiving terminal works, it is required to search for the relevant frequency point, switch to the working frequency point to receive the multimedia broadcast signal, and use the multimedia broadcast service, and the electronic service guide is also one of the multimedia broadcast services.

To save on-air transmission bandwidth, the general electronic service guide only transmits at a certain frequency.
