Patent number: 10638133Abstract: Techniques and systems are provided for processing video data. For example, an apparatus (e.g., a coding device, such as an encoder) can receive a residual portion of a block of a frame of the video data. The block is a first block in a row of the frame. The apparatus can receive a quantization parameter (QP) value determined for the residual portion of the block, and can determine all transform coefficients of the residual portion of the block have zero values. The transform coefficients can include quantized transform coefficients. The device can compare the received QP value determined for the residual portion of the block to a threshold QP value, and can determine a final QP value for the residual portion of the block based on whether the received QP value is greater than the threshold QP value.Type: GrantFiled: January 31, 2018Date of Patent: April 28, 2020Assignee: QUALCOMM IncorporatedInventors: Xue Fang, Srikanth Alaparthi

Patent number: 10284851Abstract: A system is provided for creating binary codewords for transform coefficients used for relating transform units (TUs) divided into coding units (CUs) in a High Efficiency Video Coding (HEVC) system. The system provides binarization of the codewords and removes unnecessary operations to reduce system complexity and increase compression performance. The system generates transform coefficients that relate the TUs and begins by providing a parameter variable (cRiceParam) set to an initial value of zero. Significant transform coefficients are converted into binary codewords based on the current value of the parameter variable, and the parameter variable is then updated with a new current value after each transform coefficient has been converted. Updating can be provided with reference to table values or the values can be provided from combination logic.Type: GrantFiled: January 18, 2013Date of Patent: May 7, 2019Assignee: GOOGLE TECHNOLOGY HOLDINGS LLCInventors: Jian Lou, Xue Fang, Limin Wang

Patent number: 10003793Abstract: In one embodiment, a method determines a pulse code modulation (PCM) flag that indicates whether a PCM mode can be used to encode or decode a portion of video. A single conditional statement is evaluated once to determine if the PCM flag indicates the PCM mode is enabled. Based on the evaluating of the single conditional statement, when the PCM flag indicates the PCM mode is enabled, the method encodes or decodes a first PCM parameter, a second PCM parameter, a third PCM parameter, a fourth PCM parameter, and a fifth PCM parameter. The first PCM parameter, the second PCM parameter, the third PCM parameter, the fourth PCM parameter, and the fifth PCM parameter are encoded or decoded consecutively without any bits or syntax between them in or from an encoded bitstream associated with the portion of video.Type: GrantFiled: March 14, 2013Date of Patent: June 19, 2018Assignee: GOOGLE TECHNOLOGY HOLDINGS LLCInventors: Xue Fang, Limin Wang
