Abstract: A derived quantization parameter for a section of a currently encoding picture of a plurality of pictures is incremented to produce an updated quantization parameter when the derived quantization parameter is less than a minimum quantization parameter for the currently encoding picture. The section is then encoded using the updated quantization parameter. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: A quantization parameter (QP) used for encoding a current picture is determined using rate control data. One or more sections of the current picture are encoded using the determined QP. After encoding the sections, the rate control data is updated based on statistical data determined from the resulting encoded sections.

Abstract: Techniques are described for training a machine learning (ML) model to determine, e.g., based on bit rate capacity, whether to encode a frame of video or not. If a frame is dropped according to output of the ML model, the next frame may be encoded at a higher quality than normal using the computing savings gained from dropping the first frame. Compressed domain information may be used to eliminate portions of a frame, but not the complete frame, from encoding.

Abstract: Techniques are described for identifying a switching point at which to switch resolutions of a video during streaming due to changing network bitrates. First quality metrics at plural bitrates are determined between selected videos and respective output videos derived from compressing and decompressing the respective selected videos. Also, second quality metrics at plural bitrates are determined between the respective selected videos and upscaled videos generated by upscaling the output video. Using the first and second quality metrics and bitrates, the switching point to change resolution during streaming is identified.

Abstract: Techniques are described for over-training a ML model on multiple gameplay videos of individual scenes of a computer game to better configure the model to reconstruct or enhance portions of the computer game at a receiver as the computer game is received over a streamlining network. Reconstruction of individual missing slices of a frame is contemplated such that a frame missing a slice need not be entirely discarded.

Abstract: Video stream data is selectively scaled so that sections within regions of interest (ROI) maintain high resolution while areas not within the region of interest are down-scaled to reduce bandwidth cost of transmission. A low compression encoder compresses sections of a video frame corresponding to one or more ROI without motion search or prediction mode decision to generate low-compression section data. The video frame is downscaled and a high compression encoder compresses the resulting downscaled video frame with prediction mode decision to generate high-compression frame data.

Abstract: Gaze tracking data is analyzed to determine one or more regions of interest within an image of a video stream. The video stream data is selectively scaled so that sections within the regions of interest maintain high resolution while areas not within the region of interest are down-scaled to reduce bandwidth cost of transmission. A scheme for reduction of motion sickness by reducing the size of the high resolution area is also claimed.
