Abstract: This disclosure describes systems, methods, and devices related to latency-adaptive viewport prediction for use in viewport-dependent content streaming. A method may include identifying, by a virtual reality (VR) or augmented reality (AR) device, first viewport data used by and received from a display device; generating a first estimated compensation latency based on at least one of a first network latency and by the processing circuitry, from among multiple candidate viewport prediction models each using a different respective time interval, a first viewport prediction model based on a comparison of the first estimated compensation latency to a first time interval used by the first viewport prediction model; generating, using the first viewport prediction model and the first viewport data, a first viewport prediction; and selecting, based on the first viewport prediction, a first content tile for rendering by the display device.

Abstract: This disclosure describes systems, methods, and devices related to enhanced low complexity enhancement video coding (LCEVC) presentation of tiles. A device may encode video data into one or more bits while applying an LCEVC organizational syntax. The device may generate a bitstream of the one or more bits based on the LCEVC organizational syntax. The device may assign a payload type value to the bitstream, wherein the payload type value indicates the LCEVC organizational syntax has been applied to the one or more bits. The device may transmit the bitstream to a device comprising a decoder.

Abstract: An apparatus to facilitate encoding video data is disclosed. The apparatus includes rendering logic to render graphics video data as frame data, fade extractor logic to extract fade effects data to be applied to the frame data to generate frame auxiliary metadata comprising the fade effects data, weighted prediction logic to receive the frame data and the auxiliary metadata and compute one or more weighted predictions on the frame data at one or more frame sequences indicated in the fade effects data and encoding logic to encode the frame data based on the one or more weighted predictions.
