In this work, we develop a novel robust scheme of two-dimensional unequal error protection (2D-UEP) for the H.264 scalable video coding (H.264/SVC) with a combined temporal and quality (SNR) scalability over packet-lossy networks. The proposed scheme combines error resilience techniques and importance measures in video coding. To avoid the waste of bits and obtain the best rate allocation, we develop...
H.264/AVC scalable video extension (SVC) adopts various advanced prediction modes to exploit the data redundancies between layers for better coding efficiency but at the cost of significantly increased computational complexity, especially for hardware realization of fractional motion estimation. This paper proposes an efficient and hardware friendly mode pre-selection algorithm which only preserves...
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...
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...
