    Abstract: A device for implementing a rate-distortion optimization (RDO)-based small transform coefficients suppression algorithm includes a processing module, a control block, and a switch. The processing module may be configured to process a prediction residual associated with a transform unit (TU) of a video frame and to generate a number of coefficients and a processed output. The control block may be configured to receive the coefficients and to generate a control signal based on the plurality of coefficients. The switch may be configured to select, as an output of the device, one of the processed output or an output of a zero-out block based on the control signal. The zero-out block may be configured to assign a zero value to each of the plurality of coefficients of the TU to suppress small transform coefficients.

    Abstract: A system includes motion vector prediction circuitry that generates motion vectors for pixel groups and pixel subgroups within the pixel groups. For a current pixel group within the currently processed picture, the motion vector prediction circuitry selects a target reference picture. Without first translating the current pixel group in accord with an offset vector, the motion vector prediction circuitry initiates generation of a default motion vector for the current pixel group. Responsive to the selected target reference picture, the motion vector prediction circuitry generates the offset vector. The motion vector prediction circuitry translates the current pixel group in accord with offset vector and determines motion vectors for pixel subgroups of the current pixel group based on the translated position of the current pixel group.

    Abstract: A video decoder or encoder can be used to convert and process different video streams having different combinations of frame rate and Chroma fidelity. Rather than setting the maximum sample rate of the encoder based on a Luma sample rate, the encoder's throughput is set based on a maximum color sample rate. Additionally, the picture buffer size can be set based on a maximum number of color pictures. An input of the video decoder receives an input video stream having a given display resolution and encoded in a first format employing a first combination of frame rate and Chroma fidelity. Processing circuitry in the decoder converts the input video stream from the first format to an output video stream having a second format, the second format having the given display resolution and employing a second combination of frame rate and Chroma fidelity different from the first combination.
