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...
Data bandwidth dominates the performance and power consumption in the video encoder design. In which a low bandwidth and bandwidth aware motion estimation design enables smooth and better video quality as well as lower power consumption on data accesses. This paper proposes a bandwidth efficient motion estimation and its hardware implementation to deal with the bandwidth issues. First, an on-demand...
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...
