Abstract: A high-speed circuit with a high-voltage (HV) driver circuit. The high-speed circuit has a driver circuit and a level shifter. The driver circuit includes HV components which are operated in an HV domain. The level shifter includes low-voltage (LV) components which are operated in an LV domain. The level shifter translates signals from the LV domain to the HV domain to generate control signals for the driver circuit. The high-speed circuit may include a protection voltage generator converting a power supply voltage and a power ground voltage to generate a first direct-current bias voltage (VBP) and a second direct-current bias voltage (VBN) to bias the LV components of the level shifter. The LV components of the level shifter include input transistors and protection transistors. Gate voltages of the protection transistors may be tied to VBP or VBN.

Abstract: A method for signaling adaptive loop filter (ALF) settings is provided. A video decoder receives data from a bitstream for a block of pixels to be decoded as a current block of a current picture of a video. The video decoder parses whether to use adaptive parameter set (APS) for filtering the current block without determining whether to select a particular APS from a plurality of APSs. When the APS is used to filter the current block, the video decoder parses a first filter selection index for selecting a filter from a set of filters in the APS. When the APS is not used to filter the current block, the video decoder signals a second filter selection index for selecting a filter from a set of default fixed filters. The video decoder filters the current block based on the selected filter. The video decoder outputs the filtered current block.

Abstract: A video decoder that implements a mutually exclusive grouping of coding modes is provided. The video decoder receives data for a block of pixels to be decoded as a current block of a current picture of a video. When a first coding mode for the current block is enabled, a second coding mode is disabled for the current block, wherein the first and second coding modes specify different methods for computing an inter-prediction for the current block. The current block is decoded by using an inter-prediction that is computed according to an enabled coding mode.

Abstract: Method and apparatus of Inter prediction for video coding performed by a video encoder or a video decoder that utilizes motion vector prediction (MVP) to code a motion vector (MV) associated with a block coded with Inter mode are disclosed. According to one method, an initial MVP candidate list is generated for the current block. When candidate reordering is selected for the current block, target candidates within a selected candidate set are reordered to generate a reordered MVP candidate list and then the current block is encoded at the video encoder side or decoded at the video decoder sider using the reordered MVP candidate list, where the selected candidate set comprises at least partial candidates of the initial MVP candidate list.

Abstract: A video codec that intelligently assigns a mode setting to a current block of pixels of a video picture of a video sequence when the current block is encoded or decoded by merge mode is provided. The current block has one or more coded neighboring blocks. Each coded neighboring block of the one or more coded neighboring blocks is coded by applying a respective mode setting that is specified for each neighboring block of the one or more coded neighboring blocks. The video codec identifies a set of one or more candidate predictors. The video codec specifies a mode setting for the current block based on the selected candidate predictor and mode settings that are specified for the one or more coded neighboring blocks. The video codec encodes or decodes the current block by using a selected candidate predictor and applying the mode setting specified for the current block.

Abstract: An exemplary video decoding apparatus includes a first decoding unit configured for decoding a first encoded block to generate first residual values, a first detecting unit configured for detecting whether all of the first residual values have a same first value, a first processing circuit configured for processing the first residual values to generate first processed residual values, and a second processing circuit configured for generating a decoded block corresponding to the first encoded block. When all of the first residual values have the same first value, the first detecting unit controls the second processing circuit to generate the decoded block without referring to the first processed residual values.
