This paper describes a novel scheme of video coding structure called Localized Video Coding (LVC) infra structure. Unlike the existing video coding standards, LVC is a video coding structure that is parallel-friendly. LVC will divide a video sequence into several sub-sequences and process them independently. LVC is a nontraditional way to parallelize video coding process, aimed at solving the existing problems of heat dissipation in chips. Every sub-sequence can be coded or decoded in a different processing unit and LVC can control a processing unit to sleep or work. Hence we can easily transfer the tasks from an overheated processing unit to a normal one. In this paper we will illustrate the LVC structure and show the results. Then we will provide an example of an improved method that shows a massive reduction in the processing time of a whole video sequence as well an encouraging video coding performance compared with the HEVC Tiles [ 1 ].
