Electronic newspaper receiving terminal and method based on CMMB (China Mobile Multimedia Broadcasting)

Abstract

The invention provides an electronic newspaper receiving terminal based on CMMB (China Mobile Multimedia Broadcasting), and the electronic newspaper receiving terminal comprises a demultiplexing module, an ESG (Electronic Service Guide) processing module, a downloading manager, a CA descrambling module and an electronic newspaper reading module, wherein the demultiplexing module is used for synchronizing the time of a CMMB system to a real-time clock (RTC), sending the information of an ESG to the ESG processing module and transmitting the received capsulation data of an expandable protocol to the downloading manager; the ESG processing module is used for extracting the service guide of electronic newspapers from the ESG and showing the service guide to users; the downloading manager is used for executing a downloading task according to a downloading schedule; the CA descrambling module is used for deciphering the received scrambled data into recognizable plaintext data; and the electronic newspaper reading module is used for showing the plaintext data to the users.

Description

technical field [0001] The present invention relates to the field of CMMB, and more specifically, to a terminal and method for receiving electronic newspapers based on CMMB. Background technique [0002] At present, electronic newspapers are getting more and more people's attention and welcome. Electronic newspapers can be roughly divided into two types. One type is an electronic newspaper based on wireless communication technology, that is, the current mobile newspaper. Users receive electronic newspapers subscribed by themselves through mobile terminals, and read electronic newspapers on their mobile terminals. Another type is Internet-based electronic newspapers. The Chinese patent application whose publication number is CN101047722A discloses a kind of media file pushing system, such as figure 1 As shown, it includes a server 12 and a terminal 11 connected through a network, the server 12 includes a storage module 121 for storing media files, and the terminal 11 incl...

AI Technical Summary

Problems solved by technology

[0003] However, although the above two types of electronic newspapers can meet the basic needs of current electronic newspaper users, these two types have different defects.

[0004] Electronic newspapers based on wireless communication technology can realize wireless downloading and browsing of electronic newspapers. However, when the electronic newspaper is a large file, and when the number of subscribers is large, the electronic newspaper based on wireless communication technology cannot be completed in a short time. Capacity users push large files

Although Internet-based electronic newspapers can use the Internet to complete the task of pushing large files to large-capacity users in a short period of time, user terminals must always be connected to the Internet, which is inferior to wireless communication technology-based electronic newspapers in terms of user experience.
