Problems solved by technology

[0005] 1. There are security issues in saving the fingerprint screen information sent by the front end separately
[0006] 2. If the file of the saved fingerprint screen display information is damaged or lost, the playback cannot realize the display of the fingerprint screen display data, and the stability performance is worrying
[0007] 3. There will be copyright disputes in the clear stream recording of some programs

Embodiment Construction

[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] figure 1 The interaction diagram of each module of the set-top box playback system according to the embodiment of the present invention is shown, and the processing flow of the set-top box playback method according to the embodiment of the present invention is shown.

[0022] Such as figure 1 As shown, the set-top box playback system that displays the fingerprint screen by recording clear streams includes a descrambling module, a playback module, a reassembly module, a recording module, and an encryption module.

[0023] The descrambling module judges whether the code stream da...

Abstract

The invention discloses a set top box playback system and method. The system comprises a playing module, a recombination module and a recording module. The playing module is used for receiving and playing the code stream data, judging whether fingerprint screen display data is transmitted to the set top box to be displayed when the code stream data is currently played, and transmitting all picture data and audio data for displaying a fingerprint screen display time period to the recombination module if the fingerprint screen display data is transmitted to the set top box to be displayed; otherwise, directly transmitting the currently played code stream data to the recording module; the recombination module is used for carrying out recombination processing on the picture data and the audio data received from the playing module to generate code stream data with fingerprint screen display content and transmitting the code stream data to the recording module; and the recording module stores the received code stream data in the form of a code stream file. According to the technical scheme provided by the invention, the fingerprint screen display and the playing content data of the fingerprint screen display time period are combined into the code stream data, so that the security of the fingerprint screen display data is improved.

Description

technical field [0001] The invention relates to the technical field of broadcast digital television, in particular to a set-top box playback system and method for displaying fingerprint screens by recording clear streams. Background technique [0002] With the continuous development of digital TV services, users' demand for recording their favorite programs is also increasing, but the recording of some programs may have copyright issues. In order to avoid copyright disputes, it is very necessary to display the fingerprint screen data of recorded programs. [0003] At present, most of the technical solutions for the clear stream recording are to realize the playback of the scrambled code stream by separately saving the data used for descrambling, and the playback display data of the fingerprint screen is also stored separately. The displayed start time stamp and The display duration is used to realize the display. [0004] However, the existing technical solutions have the ...
