Mobile television television broadcasting control system and broadcasting network and method

Abstract

The invention discloses control system for displaying mobile TV program, also discloses mobile TV displaying network based on the said system. Through mobile communication network, the control system for displaying mobile TV program connected to mobile terminals wirelessly is in use for authenticating authority of mobile terminal, and relation of service subscription. Being connected to mobile TV broadcast system, the control system receives service information from the said broadcast system, and synchronizes relation of service subscription, as well as creates service cipher keys and sends the keys to mobile terminals and mobile TV broadcast system. The invention also discloses method for playing mobile TV program based on the control system for displaying mobile TV program. Sending cipher keys directionally, the invention prevents deciphering cipher keys in multicast. Advantages are: avoiding high occupancy rate for network resources, supporting interactive service.

Description

technical field [0001] The present invention relates to a mobile TV broadcast control system, a broadcast network and a broadcast method based on the control system, in particular to a mobile TV broadcast control system combining a mobile communication network and a broadcast TV network. Based on the mobile TV broadcast The broadcasting network of the control system and the program broadcasting method through the mobile TV broadcasting control system belong to the technical field of mobile communication. Background technique [0002] With the development of communication technology, users are no longer satisfied with watching TV programs at fixed terminals, but hope to watch their favorite programs at any time while freely moving. [0003] At present, the development of broadcasting technology has realized the broadcasting of TV programs to mobile terminals through the broadcasting TV network, so that users can watch TV programs whether they are indoors or outdoors, local or...

AI Technical Summary

Problems solved by technology

[0005] First, the broadcasting of TV programs can be encrypted, but the key can only be sent in groups and cannot be sent in a targeted manner; therefore, even if only one user chooses to watch a certain program, the broadcasting network must Issuing keys to all user terminals in the coverage area causes unnecessary waste of system resources and network bandwidth, and also increases the probability of key cracking, which is not conducive to ensuring the business security of operators and is not conducive to the verification of user qualifications. valid certification;

[0006] Second, when a TV program is sent by broadcast, the broadcast TV network has no way of knowing whether the terminal has received the TV program. In order to ensure successful reception, it can only be sent repeatedly, which brings a huge load and waste to the system;

[0007] Third, sending TV programs through broadcasting is a one-way transmission, and users cannot give feedback, so they can only receive passively, but cannot actively participate; therefore, it is not conducive to users to obtain a good experience, nor is it conducive to the development of value-added services

[0010] First, the bandwidth provided by the mobile communication network is insufficient, so the user's viewing effect cannot be guaranteed;

[0011] Second, the network bandwidth and server resources of SP / CP are limited by the number of users. Therefore, if there are many users watching at the same time or encountering network congestion, the viewing effect of users cannot be guaranteed
