Patent number: 10104401Abstract: The latest High Efficiency Video Coding (HEVC) standard achieves significant compression efficiency improvement over the H.264 standard, at a much higher cost of computational complexity. A framework for software-based H.264 to HEVC transcoding on multicore processors and distributed systems is provided. By utilizing information extracted from the input H.264 bitstream, the transcoding process can be accelerated at a high ratio with modest visual quality loss. Wavefront Parallel Processing (WPP) and SIMD acceleration are also implemented to improve the trans coding efficiency on multi-core processors with SIMD instruction set extensions. Based on the HEVC HM 12.0 reference software and using standard HEVC test bitstreams, the proposed transcoder can achieve around 120× speed up over decoding and re-encoding based on ffmpeg and the HM software without significant R-D performance loss.Type: GrantFiled: March 19, 2015Date of Patent: October 16, 2018Assignee: NANJING YUYAN INFORMATION TECHNOLOGY LTD.Inventors: Jiangtao Wen, Yucong Chen, Ziyu Wen, Tong Shen

Patent number: 9924183Abstract: The emerging High Efficiency Video Coding (HEVC) standard achieves significant performance improvement over H.264/AVC standard at a cost of much higher complexity. An H.264/AVC to HEVC transcoder is described for multi-core processors implementing Wavefront Parallel Processing (WPP) and SIMD acceleration, along with expedited motion estimation (ME) and mode decision (MD) by utilizing information extracted from the input H.264/AVC stream. Experiments using standard HEVC test bitstreams show that the described transcoder may achieve a 70× speed up over the HEVC HM S.1 reference software (including H.264 encoding) at very small rate distortion (RD) performance loss.Type: GrantFiled: March 19, 2015Date of Patent: March 20, 2018Assignee: NANJING YUYAN INFORMATION TECHNOLOGY LTD.Inventors: Jiangtao Wen, Yucong Chen, Ziyu Wen, Tong Shen

Patent number: 7825993Abstract: The present invention suggests a simplified and robust scanning method as a scenario for scanning video sources of a display device such as a TV or projector. The inventive method is attained by way of grouping the video sources and prioritizing the scanning priority for each video source group in terms of the viewing time statistic or the frame number statistic of each video source group. Therefore, the display device is capable of scanning each video source group based on the scanning priority to discover if there is a video signal inputted into the video source.Type: GrantFiled: August 4, 2006Date of Patent: November 2, 2010Assignee: Acer IncorporatedInventors: Shih-Tong Shen, Kuang-Peng Ho

Patent number: 4491390Abstract: An automatic liquid-crystal light shutter includes a NAND gate integrated circuit and a pair of RC oscillators operating in cooperation with two solar cells which experience internal resistance changes in response to received light. The changes in the internal resistance of the two solar cells results in a comparison signal which is applied to each of two NAND gates along with respective oppositely faced oscillator signals. When the NAND gate output signals are of different potential, the shutter passes light with little or no attenuation. If the NAND gate output signals are of the same potential, the liquid-crystal shutter becomes highly attentuated or unpassable for light. As a result, the automatic liquid-crystal shutter automatically passes low intensity light but attenuates or blocks high intensity light.Type: GrantFiled: May 6, 1982Date of Patent: January 1, 1985Inventor: Hsieh Tong-Shen
