Methods and equipment for encoding video and invariable media read by computers

Abstract

Decoding refers to the methods and equipment used to decode video signals and other readings obtained using computers. The method of decoding a video bitstream using at least one processor includes: receiving the source video sequence from the video source; encoding and compressing the source video sequence into an encoded video sequence; the encoded video sequence includes a first syntactic element indicating the number of classes in the encoded video sequence; a second syntactic element indicating whether the classes in the encoded video sequence are all independent classes; The third syntax element indicates the output mode based on the first syntax element, which states that the number of classes is greater than one, and the second syntax element indicates that not all classes are independent classes.
