Abstract

The invention discloses a video encoding complexity adaptive regulation method and device. The method comprises the following steps: pre-classifying macro block encoding modes; calling a complexity control module, preliminarily calculating a calculation complexity required by encoding according to the pre-classified encoding modes, comparing the pre-estimated calculation complexity with a target calculation complexity, and entering into subsequent video encoding procedures for performing movement estimation and mode selection when the pre-estimated calculation complexity meets the given target calculation complexity; otherwise, regulating the macro-block-grade calculation complexity until the target complexity requirement is reached. The invention also discloses a video encoding complexity adaptive regulation device. The device comprises a macro block pre-classification unit, a complexity estimation unit and an encoding complexity control unit. According to the method and device provided by the embodiment of the invention, when a power supply capability of a power source is insufficient, the encoding parameters can be regulated actively, the encoding complexity can be reduced, andsimultaneously the quality of reconstructed video can also be ensured.

Description

technical field [0001] The present invention relates to the field of digital video processing, in particular, the present invention relates to a video encoding complexity self-adaptive adjustment method and device. Background technique [0002] Video is one of the most important information carriers for human beings because of its intuitive, vivid and rich content. With the rapid development of information technology, various video applications such as wireless multimedia communication and digital TV have higher and higher requirements for video resolution. The growth rate of capacity. Therefore, video coding technology has become a key research topic in the field of information technology, and has attracted extensive attention from academia and industry. [0003] The two major international organizations in the field of video, ISO-MPEG and ITU, have successively launched a series of video compression standards such as MPEG-1, MPEG-2 and MPEG-4 and H.261, H.263, H.263+, H....
