Embodiment 1

[0092] In this embodiment, the two-way interactive access network interconnected with the mobile video broadcast network is a mobile access network, and a schematic diagram of the interconnection of these two networks is shown in FIG. 4 .

[0093]Wherein, the mobile communication terminal 401 sends the conditional access request data to the mobile access network 403 through the base transceiver station (BTS) 402, and the mobile access network 403 sends the conditional access request data to the data transmission network 404, and the data transmission The network 404 sends the request data to the conditional access server 406 through the service gateway 405 of the service center in the MVB network.

[0094] After the conditional access server 406 processes the received conditional access request data, it sends the generated conditional access response data to the video production server 407 . The video production server 407 transmits the conditional access response data to the ...

Embodiment 2

[0119] In this embodiment, a schematic diagram of the interconnection between the MVB network and the intelligent network is shown in FIG. 6 . The intelligent network includes: a telephone network (PSTN) 602 , a queuing machine 603 , a call controller 604 and a voice server 605 . Among them, the queuing machine 603, the call controller 604 and the voice server 605 are interconnected with the service center 607 of the MVB network through the data transmission network 606.

[0120] The user uses an intelligent network terminal such as a fixed telephone 601 to connect to the PSTN 602, and sends an access request to the queuing machine 603, and the queuing machine 603 passes the above-mentioned access request to the call controller 604, and the call controller 604 allocates a voice server 605 for the user . The voice server 605 verifies the access request sent by the user, and sends conditional access request data to the service gateway 608 of the service center 607 in the MVB ne...

Embodiment 3

[0138] In this embodiment, a schematic diagram of the interconnection between the mobile video broadcast network and the asynchronous digital subscriber network (ADSL) is shown in Figure 8, and the ADSL includes: a user service link access multiplexer (DSLAM) 803 and an ADSL modulator (Modem )802.

[0139] The user uses a terminal such as a computer 801 to connect to the ADSL modulator 802, and sends the conditional access request data to the DSLAM 803 through the ADSL modulator 802, and the DSLAM 803 sends the conditional access request data to the data transmission network 804, and the data transmission network 804 passes the MVB The service gateway 805 of the service center in the network sends the conditional access request data to the conditional access server 806 .

[0140] After the conditional access server 806 processes the received conditional access request data, it sends the generated conditional access response data to the video production server 807 . The video ...

Abstract

The invention relates to a method for realizing bidirectional condition access in mobile video broadcast network. Wherein, said method comprises that the user of mobile video broadcast terminal via bidirectional interactive terminal accesses into bidirectional interactive access network, to access into mobile video broadcast network, and send the condition access request via said connection to the mobile video broadcast network; mobile video broadcast network receives the request and inserts decrypt information with decrypt key in the descending transmission flow, to be broadcasted to the mobile video broadcast terminal. The invention instantly triggers MVB network to send decrypt information to user via bidirectional interactive access network to meet the demand of shortest receive time when the MVB terminal is started, reduce the transmission frequency of decrypt message and save bandwidth.

Description

technical field [0001] The invention relates to mobile video technology, in particular to a method and system for realizing two-way conditional access in a mobile video broadcasting network. Background technique [0002] At present, the mobile video broadcasting (MVB) service is more and more welcomed by users, and has a very good development trend in the communication market. A mobile video broadcast system dedicated to supporting mobile video services is shown in FIG. 1 , including a service center 101 , a data transfer network 102 , a service encapsulator 103 , a broadcast transmitting station 104 and a mobile video broadcast terminal 105 . The service center 101 is a complex system for service management and user management, mainly including: a video production server 106 and a conditional access server 107 . [0003] The process of using the mobile video broadcasting system shown in Figure 1 to provide MVB services is as follows: [0004] 1. The video production serve...
