Abstract

The invention discloses a descrambling processing method, device and equipment and a storage medium. The method comprises the following steps: receiving a program mapping table of a target program ina digital terminal, acquiring an audio and video packet identifier in the program mapping table, opening an audio and video decoding channel, and sending a callback processing notification to a condition receiving module in the digital terminal based on the audio and video decoding channel; receiving the program mapping table of the target program in the digital terminal, acquiring a control wordand a descrambler which correspond to the program mapping table, associating the descrambler with the audio and video packet identifier, and detecting whether the descrambler and the audio and video packet identifier are successfully associated or not; if the descrambler and the audio and video packet identifier are not successfully associated, storing the control word, and associating the descrambler and the audio and video package identifier again according to the callback processing notification till the association is successful; and if the association is successful, setting the descrambler according to the control word, and descrambling the target program. The descrambling processing method solves the technical problem that the descrambler cannot descramble a program due to a timing problem.

Description

technical field [0001] The present invention relates to the technical field of digital terminals, in particular to a descrambling processing method, device, equipment and computer-readable storage medium. Background technique [0002] With the popularization of digital TV, many families have used digital TV receiving terminals to watch digital TV. Channel switching has always been an important indicator for verifying digital TV receiving terminals, and it also directly affects the user experience. The channel switching is mainly affected by the descrambling of the target program by the descrambler in the digital TV. [0003] At present, the way for digital TV to descramble is usually to open the audio and video decoder associated with the target program first, decode the target program, and then perform descrambling, but if the audio and video decoder associated with the target program is not turned on , it will cause the descrambler to fail to descramble. Therefore, how ...
