Abstract: Systems and methods may provide for capturing 360 degree video, and multi-resolution encoding, processing and displaying of the video based on a field of view (FOV) and region of interest (ROI) for a viewer. The ROI may be determined based on eye tracking information (ETI) and the video may be encoded for viewports within the FOV at a high resolution and for other viewports outside the FOV at a lower resolution. ROI in the video may be encoded at a high resolution and areas outside of the ROI may be encoded at a lower resolution. The ETI enables the selective display of one or more warnings based on the gaze of a user to improve the efficiency of the warning. 3D glasses having variable lens may be used to adjust the focal distance of a virtual display to match a virtual distance of an object based on stereo distance cues.

Abstract: Embodiments described herein provide an apparatus comprising a processor to divide a first point cloud data set frame representing a three dimensional space at a first point in time into a matrix of blocks, determine at least one three dimensional (3D) motion vector for at least a subset of blocks in the matrix of blocks, generate a predicted second point cloud data set frame representing a prediction of the three dimensional space at a second point in time by applying the at least one 3D motion vector to the subset of blocks in the matrix of blocks, compare the predicted second point cloud data set frame to a second point cloud data set frame representing a prediction of the three dimensional space at a second point in time to generate a prediction error parameter, and encode the second point cloud data set frame as a function of the first point cloud data set frame and the at least one three dimensional (3D) motion vector when the prediction error factor is beneath an error threshold to produce an encoded second point cloud data set frame. Other embodiments may be described and claimed.

Abstract: Techniques related to determining chroma quantization parameters for video coding are discussed. Such techniques may include generating first and second chroma quantization parameter offsets for first and second picture of a video sequence having a hierarchical coding structure such that the second chroma quantization parameter offset is greater than or equal to the first chroma quantization parameter offset in response to the first picture having a higher quality priority than the second picture.

Abstract: In some embodiments, independent workloads may be grouped together into a single super workload. This super workload is dispatched to a single context hardware system that does not run an operating system. This effectively creates a multi-context system out of a single context hardware processor.

Abstract: Techniques related to video coding with sample adaptive offset coding are discussed. Such techniques may include setting a sample adaptive offset coding flag for a picture of a group of pictures based at least in part on a comparison of an available coding bit limit of the picture to a first threshold and a quantization parameter of the picture to a second threshold. In some examples, such techniques may also include setting the sample adaptive offset coding flag based on a coding structure associated with coding the group of pictures.

Such techniques may include comparing individual prediction residues of a unit of a picture of video such as a coding unit to an adaptive threshold and splitting a transform unit corresponding to the unit if any of the prediction residues exceed the adaptive threshold.

Abstract: Techniques related to video coding with low bitrates are discussed. Such techniques may include skipping coding of a picture of a group of pictures when an estimated coding bit cost of the picture is greater than an available coding bit limit for the picture and, when the estimated coding bit cost is not greater than the available coding bit limit, determining the coding skip indicator based on a picture type of the individual picture and a picture structure of the group of pictures.

Abstract: Systems and methods for determining a target number of bits (target bitrate) for encoding a frame of video that will satisfy a buffer constraint in a parallel video encoder. The quantization parameter (QP) for a given encoding process may be determined for the frame based on the target bitrate to maintain a suitable average bitrate. In some embodiments, the bitrate used for one or more prior frame is estimated. In some embodiments, a buffer fullness update is made based on an estimated bitrate. In some embodiments, a bitrate to target for each frame is determined based on the frame type, estimated bitrate of a prior frame(s), and the updated buffer fullness.

Abstract: Techniques related to quantization parameter estimation for coding intra and scene change frames are discussed. Such techniques include generating features based on an intra or scene change frame including a proportion of smooth blocks and one or both of a measure of block variance and a prediction distortion, and applying a machine learning model to generate an estimated quantization parameter for encoding the intra or scene change frame.
