Abstract

The invention discloses a multi-channel high-definition live program forwarding method and system based on a broadcast television network home gateway. The multi-channel high-definition live program forwarding method comprises the following steps: providing a high-definition live program by various market-oriented intelligent terminals such as internet set top boxes, mobile phones, tablet computers, intelligent motors by the broadcast television network home gateway, obtaining data of the live program by virtue of a wired television network according to ID of the live program sent by the intelligent terminals by a live program obtaining module of the home gateway; demodulating and descrambling the received live program data by a demodulating and descrambling module; encrypting the demodulated and descrambled live program data again by an encrypting module; sending the encrypted high-definition live program data and decrypting keys to the intelligent terminals by a live program distributing module; decrypting and playing the encrypted live program data by the intelligent terminals. The multi-channel high-definition live program forwarding method and system can be used for watching different live programs on a plurality of different intelligent terminals.

Description

technical field [0001] The invention relates to a method and system for forwarding multi-channel high-definition live programs based on a broadcast television network home gateway. Background technique [0002] In the existing system of broadcasting and TV broadcasting live TV programs, the request for watching live TV programs is generally issued by the specific set-top box terminal of radio and television. Each set-top box corresponds to a TV set, and the set-top box sends the request from the remote control to the front end of the digital TV Platform, the digital TV front-end platform transmits the live TV program data to the set-top box through the cable TV network, and the set-top box demodulates the live TV program data and transmits it to the TV for viewing. The above-mentioned method of controlling live TV based on the set-top box, the broadcasting and viewing control of the set-top box mainly adopt CA authorization, which is equivalent to the front-end directly...
