—The latest video coding standard high-efficiency video coding (HEVC) provides 50% improvement in coding efficiency compared to H.264/AVC to meet the rising demands for video streaming, better video quality, and higher resolution. The deblocking filter (DF) and sample adaptive offset (SAO) play an important role in the HEVC encoder, and the SAO is newly(More)
The speed of a quantum random number generator is essential for practical applications, such as high-speed quantum key distribution systems. Here, we push the speed of a quantum random number generator to 68 Gbps by operating a laser around its threshold level. To achieve the rate, not only high-speed photodetector and high sampling rate are needed but also(More)
—In the High Efficiency Video Coding (HEVC) standard , a notation of the transform unit (TU) is introduced with four different sizes, i. which results in at least two problems in the use of discrete cosine transform/inversed discrete cosine transform (DCT/IDCT). One is changeable input/output format presented by DCT/IDCT when it deals with TUs of different(More)
—The next generation standard of coding, High Efficiency Video Coding (HEVC) aims to provide significantly improved compression performance in comparison with all existing video coding standards, such as MPEG-4, H.263, and H.264/AVC. The tool of rate-distortion optimization (RDO) mode decision has proven to be extremely important. Due to the increase in the(More)
