Title: VIDEO PROCESSING METHOD AND DEVICE
Abstract:
Disclosed in embodiments of the present invention are a video processing method and a device, relating to the field of communications technology, and capable of, while in the process of playing a first clear stream and recording a second scrambled stream, switching to play a second clear stream; in addition, when in the process of playing back the recorded second scrambled stream, realizing fast-forward playing or fast-reverse playing. A specific solution is: receiving a transport stream (TS), the TS comprising a first scrambled stream and a second scrambled stream; transmitting the first scrambled stream and the second scrambled stream to a decoding device; sending a first control instruction to the decoding device; receiving a first clear stream and a second scrambled stream transmitted by the decoding device, the first clear stream being decoded from the first scrambled stream; playing the first clear stream and recording the second scrambled stream, and generating at least one scrambled stream index while recording the second scrambled stream. Embodiments of the present invention may be used in the process of video playing and TS recording.
