H.264 Video Coding-Based Motion Estimation Architecture for Video Broadcasting from a Studio

Motion estimation (ME) as a process in H.264 coding basically deals with huge number of image data and needs a lot of calculation so that it should be considered to improve by hardware implementation and data redundancy reduction. This paper proposes an H.264 coding-based motion estimation architecture for video broadcasting from a studio. To implement a hardware of motion estimation, parallel processing is logically applied in the preprocessing and keypoint finding processes, and time-domain based algorithm is replaced by the frequency-domain based algorithm in order to filter the informative data in the low frequency range. The experimental results show that the proposed H.264 coding-based motion estimation architecture achieved significant improvement while maintaining the signal quality.
