Abstract

The invention discloses a digital television signal distribution method and system, a receiving device and a terminal device. The digital television signal distribution method comprises: sending video program information to a digital television signal receiving end, and receiving an encrypted video fed back by the digital television signal receiving end according to the video program information; sending license request data to a digital television signal receiving end according to the encrypted video, and receiving license information sent by the digital television signal receiving end, the license information being sent by the server when terminal binding information corresponding to the digital television signal receiving end is matched with the license request data; and decrypting the encrypted video according to the license information to obtain audio and video data. The audio and video data are acquired by communicating with the digital television signal receiving end, so that the network load is reduced, the problems that the television video is often stuck and the definition of a film source is relatively low are solved, and then the user experience is improved.

Description

technical field [0001] The present invention relates to the field of digital television, in particular to a digital television signal distribution method, system, receiving device and terminal device. Background technique [0002] In related technologies, watching live TV on a terminal device will share the same network with digital TV signal receiving equipment, which not only increases the network load, but also fails to obtain some specific TV resources. How to share all the TV resources while reducing the network load, and ensure the security of the obtained resources has become an urgent problem to be solved. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a method for distributing digital television signals, which can reduce network load and enable terminals to share all television resources. [0004] The invention also provides a...
