Problems solved by technology

Since H.264 uses a 4×4 size DCT transform, 4×4 is a relatively small size, so the discontinuity problem can be alleviated to some extent, but it cannot be completely eliminated
[0012] The second reason is motion compensated prediction
[0018] However, since the deblocking filter is applied to each layer in a multi-layer based video encoder / decoder, it is not necessary to resolutely apply the deblocking filter to the frame provided from the lower layer in order to efficiently predict the current layer frame. reasonable

Abstract

A deblocking filter used in a video encoder / decoder based on a multilayer is disclosed. The deblocking filtering method includes choosing a present block and its neighboring block on which a deblocking filtering will be performed, judging whether the present block and the neighboring block have been coded by the intra BL mode, choosing a deblocking filter strength according to the result of the judgment, and performing the deblocking filtering with respect to a boundary between the present block and the neighboring block and according to the deblocking filter strength.

Description

technical field [0001] The present invention relates to video compression technology, and more particularly, to a deblocking filter used in a multi-layer video encoder / decoder. Background technique [0002] Along with the development of information and communication technology, in addition to text communication and voice communication, multimedia communication is also increasing. Existing text-centric communication systems are insufficient to meet various needs of consumers, and therefore, multimedia services capable of providing information in different forms such as text, images, music, etc. are becoming more and more numerous. Since the amount of multimedia data is large, a large-capacity storage medium and a wide bandwidth are required to store and transmit multimedia data. Therefore, compression encoding technology is required to transmit multimedia data including text, image and audio data. [0003] The basic principle of data compression is t...
