Apparatus and method for encoding/decoding additional intra-frame information

Abstract

The present disclosure provides an apparatus for encoding additional intra-information includes an intra prediction mode selecting unit for performing an intra prediction by applying at least one of one or more predetermined types of partitions and one or more prediction modes with respect to a coding unit, and for selecting at least one of a partition among the one or more types of partitions and a prediction mode among the one or more prediction modes; a partitioning and prediction mode table lookup unit for looking up a table, and for generating a table hit signal if the table has at least one of a partition corresponding to the selected partition and a prediction mode corresponding to the selected prediction mode; and an entropy encoding unit for performing an encoding based on the table, if the table hit signal is received.

Description

technical field [0001] Embodiments of the present disclosure relate to devices and methods for encoding / decoding additional intra information. More specifically, embodiments of the present disclosure aim to efficiently encode / decode additional intra-frame information due to increasing image sizes and resolutions in video data compression devices and increasing various methods of partitioning encoded blocks. , and relates to an apparatus and method for encoding / decoding additional intra-information capable of adaptively reducing information when encoding / decoding additional information by effectively managing division information and prediction mode information patterns of previous blocks using a history table quantity. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] In an apparatus for compressing video data, intra-coding is performed to efficient...

AI Technical Summary

Problems solved by technology

In this case, a higher compression rate can be achieved by performing intra prediction on a finer image, but additional information is required in order to decode it, i.e., many signals such as the block division method and the intra prediction mode, which makes it difficult to increase the overall compression ratio
