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.
