HEVC Adaptive Frame Memory Compression Method based on Hierarchy Reference Frame Structure for an HEVC Encoder

摘要

The present invention relates to a method of compressing a frame memory based on a hierarchical reference frame structure of an HEVC encoder, A second step of reading data of the HEVC encoder from the FMC module, a second step of compressing the data according to a different compression ratio for each layer in the FMC module, and a step of storing the compressed data generated in the FMC module in a frame memory And a third step of performing the second step. According to the present invention, there is an effect of compressing data by applying different compression ratios according to a layer used in a compression method of a frame memory based on a hierarchical reference frame structure, thereby reducing image quality degradation due to FMC, and reducing loss in important data .
