Embodiment 1
[0050] Step 1, the configuration process, includes the following two steps:
[0051] Step 110, identify the possible representation methods for all the values of a syntax element, and obtain the identification information of the representation methods;
[0052] The values of the syntax elements described herein include at least three or more. Taking the value of the syntax element including three kinds as an example, three signs of A, B, and C are used to indicate whether the syntax element is equal to the above three values, and there are six ways of expressing the value of the syntax element: A-B-C, A-C-B, B-C-A, B-A-C, C-A-B, C-B-A, the identifier of each representation method represents a codeword allocation method of the syntax element, for example, A-B-C means: first distinguish the A identifier, then distinguish the B identifier, and finally distinguish the C identifier.
[0053] Step 120, establishing an encoding data structure according to the encoding attribute,...
Embodiment 2
[0082] In this embodiment, description is made by taking the syntax element as a prediction mode as an example. For ease of description and implementation, this embodiment only uses the three most frequently occurring values of prediction modes: skip mode (SKIP), merge mode (MERGE), and inter-frame mode (INTER) as examples for illustration.
[0083] Step 210, the prediction type (pred_type) is initialized;
[0084] The prediction type (pred_type) refers to: the representation method corresponding to the prediction mode, that is, the identification sequence of the prediction mode is represented by a group of identifications.
[0085] In Table 2, six identification orders corresponding to the three prediction modes of SKIP, MERGE and INTER are defined. The order of these identifications is the different values of the prediction type (pred_type), which is equivalent to the identification information of the representation method.
