The latest video coding standard called high efficient video coding (HEVC) has been standardized recently to provide higher coding performance than previous state-of-the-art video coding standard H264/AVC. However, the near 50% bitrate reduction compared to H.264/AVC mainly comes from the adoption of several advanced coding techniques but at the expense of increased coding complexity as well as hardware...
To support inter-layer prediction with arbitrary frame resolution ratio between successive spatial layers, the scalable video coding (SVC) adopts the mechanism of extended spatial scalability (ESS) to achieve it but with noticeable hardware implementation complexity due to the numerous multiplication operations. Therefore, this paper proposes a hardware efficient inter-layer prediction architecture...
A high throughput context-based adaptive binary arithmetic coding (CABAC) decoding design with hybrid memory architecture for H.264/AVC is presented in this paper. To accelerate the decoding speed with hardware cost consideration, a new hybrid memory two-symbol parallel decoding technique is proposed. In addition, an efficient mathematical transform method is also proposed to further decrease the...
Motion estimation process is the most computational and memory intensive component in video encoders. However, traditional motion estimation algorithms focus on rate and distortion performance and do not take memory bandwidth into consideration. As a result, its performance will be degraded under bandwidth constraint environment. In this paper, a bandwidth-rate-distortion optimized motion estimation...
In this paper, the first overall memory analysis for H.264/AVC scalable extension (SVC) is presented. Since the dependency among layers is a major discrepancy between SVC and H.264/AVC, the hardware design about them is quite different. Therefore, we analyze the memory bandwidth and memory access requirement of different coding flows for SVC. Based on the analysis results, we deduce that the frame-level...
In this paper, a memory efficient Fine Grain Scalability (FGS) coefficient encoding method is proposed to reduce the external memory access requirement. In the H.264/AVC Scalable Video Extension, the FGS coefficients encoding is frame based. However, the frame based mechanism results in the difficulty of hardware implementation due to large internal memory requirements and external memory accesses...
In this paper, a fast block-based motion estimation algorithm which combines the finite-state side match concept for H.264 video coding standard is proposed. The proposed algorithm performs the side matching for each candidate position within the search window and chooses several positions which have least side match sum of absolute difference to form a finite-state motion vector set. Afterwards,...
