Abstract

The invention reveals a method of encoding and a device, a method of decoding and a device, a device, a recording device, and a computer program, and relates to the field of encoding and decoding technology. In this method, the first implicit variable is scaled based on the first variation scaling factor, to obtain the second implicit variable, and the number of encoded bits of the entropy encoding result of the second implicit variable satisfies a predetermined encoding rate condition. This ensures that the number of encoded bits of the entropy encoding result of the implicit variable corresponding to each frame of multimedia data can satisfy the predetermined encoding rate condition, i.e., the number of encoded bits of the entropy encoding result of the implicit variable corresponding to each frame of multimedia data can be essentially consistent, rather than dynamically changing, thereby satisfying the encoder's requirement for a stable encoding rate.
