Problems solved by technology

At present, the more common clearing program broadcast control scheme is the clearing program playback control within the same network, such as controlling the playback of DTT clearing programs through the DTT network. There is no cross-network clearing program control solution, such as controlling the playback of DTT network clearing programs through the DTH network

Embodiment Construction

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0029] As mentioned above, the inventors found that currently the more common clearing program broadcast control solution is the clearing program broadcast control within the same network, and there is no cross-network clearing program broadcast control solution, but in fact there is a demand for cross-network clearing program broadcast control . For cross-network clearing programs, without any control, there will be two extreme situations:

[0030] 1. Let the cross-network clear stream programs be left alone. Even if users do not pay fees, they can still watch at wi...

Abstract

The invention discloses a digital television program cross-network playing control method, a terminal set-top box and a front-end broadcast system. The method comprises the following steps: the terminal set-top box of a first network receives a transmission stream provided by a second network; the transmission stream comprises a second network clear stream program; a network information table NIT in the transmission stream comprises a network describer, and the network describer comprises playing control authority and authorization description information of the second network clear stream program; when the terminal set-top box conforms to the playing control authority, the terminal set-top box stores the second network clear stream program; when authority specified by the authorization description information is stored in a user intelligent card, the terminal set-top box displays the second network clear stream program; and if the authority specified by the authorization description information is not stored in the user intelligent card, the terminal set-top box hides the second network clear stream program. By adoption of the digital television program cross-network playing control method disclosed by the invention, cross-network playing control of clear stream programs can be realized.

Description

technical field [0001] The invention relates to the technical field of television, in particular to a digital television program cross-network broadcast control method, a terminal set-top box and a front-end broadcast system. Background technique [0002] Currently, there are two types of programs in the digital TV broadcasting system. One type is scrambled through the front-end broadcasting system. After the terminal set-top box receives the program, it needs to descramble the program through a smart card before the user can watch the program. When the user recharges the smart card, the scrambled program can be descrambled. If the user does not recharge the scrambled program, the scrambled program cannot be descrambled, and the user cannot watch the program. The other type is clear stream programs without scrambling. After the terminal set-top box searches for these programs, the user can always watch them, even if the smart card is not recharged and the program is in an un...
