Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0027] first:

[0028] a. The national radio and television business cooperates with TV equipment vendors to define standard digital TV equipment software and hardware interfaces and application function modules; b. TV equipment vendors establish digital TV terminal equipment that matches a; c. The national radio and television business establishes digital TV equipment that matches b USB hardware carrier device.

[0029] The dynamically loadable authorization module released by the national radio and television company can be assigned a unique serial number, plus the unique identification number of the relevant hardware of the digital TV terminal equipment that we have purchased in our family. The user identification number ID that can be submitted to the radio and television company when a paid service is required. Since the USB hardware carri...

Abstract

The present invention discloses a digital television terminal implementing method based on USB authorization mode which loads a standard authorization module and an application function module of radio and television operators through USB apparatus. The invention is characterized by: a. defining a standard hardware and software interfaces and application function module of the digital television apparatus; b. establishing a digital television terminal equipment matching with step a; establishing a USB hardware carrier apparatus matching with the step b. The invention also includes the following steps: a tuning step, a channel demodulation and decoding step, a source decoding step, a judging step, a determining step, and a video and audio decoding step, wherein, in the source decoding step, the working principle of the descrambling and decryption function module in the USB is identical to the working principle of a receiving control module in the conventional conditional access system CA. The invention can protect the benefits of terminal equipment manufacturers and local radio and television operators in a maximum extent, to reach the object of effective and full use of the resources.

Description

technical field [0001] The invention belongs to the field of television conditional access systems, in particular to a method for realizing a digital television terminal based on a USB authorization mode. Background technique [0002] In the current digital TV implementation plan, radio and television operators in various places use different conditional access system CAs, and the viewing authorization interface and application software function modules are not unified, which leads to equipment manufacturers needing to customize different versions of software for different regions, artificially causing reception The regional differences of equipment cannot achieve the universality of equipment, and the essence of the problem is that the main party to realize the differences is the local radio and television rather than equipment manufacturers. [0003] In the digital TV system, CA is an important means to ensure that users pay for viewing. At present, the conditional access...
