Electronic service guide information update method for handheld digital video broadcasting

Abstract

The invention discloses a method for updating electronic service guide (ESG) information in a handhold digital video broadcast, which includes the following processes: A. a catalogue structure linked list of segment information of the ESG is established; B. after receiving a vessel file, the ESG looks over and compares the catalogue structure linked list and judges the updating type; C. the vessel file which has changed is analyzed and the segment information is obtained and then sent to be applied to service; D. the catalogue structure linked list is updated. In the invention, the catalogue structure linked list only needs to be looked over and compared and then the updating type of the ESG can be judged; besides, only the vessel files which have been changed are analyzed and as the vessel files are not completely looked over and analyzed, a great amount of time and resource is saved for the system. The invention can also use the catalogue structure in an initial vessel of the ESG for establishing the catalogue structure linked list of the segment information of the ESG so as to avoid additional memory spending for storing the segment information of the ESG, thus saving a large amount of memory resource for the system.

Description

technical field [0001] The present invention relates to the field of mobile phone televisions, in particular to a method for implementing ESG (Electronic Service Guide, Electronic Service Guide) information update in DVB-H (Digital Video Broadcasting Handheld, Handheld Digital Video Broadcasting). Background technique [0002] With the popularity of mobile data services, the improvement of mobile phone performance, and the rapid development of digital TV technology and networks, the mobile TV service of watching TV with smart phones or 3G mobile phones with operating systems and video functions has attracted widespread attention. Due to the high penetration rate of mobile phone users and the convenience of carrying mobile phones, the mobile TV business has shown a wider influence than ordinary TV. The DVB-H standard is a very influential terrestrial digital TV broadcasting standard among mobile TV standards, and has been vigorously promoted and applied in many countries, esp...

Problems solved by technology

This method needs to increase message interaction. If the ESG stores a lot of information, the amount of messages transmitted will be large, which will affect the performance of the normal operation of the system.

[0016] In summary, although the above-mentioned existing technologies can realize ESG information update, they are cumbersome, and additional consideration needs to be given to the large amount of memory resources required for ESG information preservation and the time consumption required for ESG information traversal.
