Detailed Description
Embodiments of the on-site resolution analysis platform of the present invention will be described in detail below.
VLC (variable-length coding), variable length coding, i.e. the length of the codeword varies from symbol to symbol when coded. Such as classical Huffman Coding (Huffman Coding), shannon-fanno algorithm, etc. For example, if there are 5 symbols A, B, C, D, E, the probability of occurrence is in turn: 0.60.20.10.050.05. if coded according to a fixed length, at least 3 bits are required. By adopting variable length coding, data can be effectively compressed; whether lossy or lossless depends on the particular encoding method.
At present, the adaptive level of VLC coding is low, and corresponding coding strategy switching cannot be executed according to the resolution of an input video picture, so that the technical problems of coding resource waste or low coding efficiency easily occur in VLC coding, and therefore a self-adaptive VLC coding mechanism is needed to give consideration to both coding efficiency and coding resources.
