Abstract: Coding tools are described for subjective quality improvements in video codecs. Some embodiments pertain to a method that includes receiving video frames, generating a segmentation map of a received video frame, determining features of a segment of the segmentation map, determining if the segment has a skip or a reference frame feature, and if the segment has one of a skip or a reference frame feature, then classifying the segment as an active segment and attaching an active segment identifier to the segment.

Abstract: A system includes a camera to capture real world content and a semiconductor package apparatus. The semiconductor package apparatus includes a substrate and logic. The logic includes a graphics pipeline to generate rendered content, a base layer encoder to encode real world content into a base layer and a first layer encoder to encode rendered content into a first non-base layer, a multiplexer to interleave the base layer with the first non-base layer to obtain a single output signal having mixed reality content, and a transmitter to transmit the single output signal. The system further includes a second layer encoder to encode map data into a second non-base layer. The multiplexer to interleave the second non-base layer with the first non-base layer and the base layer. The first and second layer encoders encode the rendered content and the map data into overlay auxiliary pictures.

Abstract: An apparatus of video encoding is described herein. The apparatus includes an encoder and a hardware bit packing unit. The encoder includes a fixed function hierarchical motion estimation search unit, fixed function integer motion estimation search units, and a fixed function check and refinement unit. The check and refinement unit is to generate residuals using nested loops based on at least one spatial domain prediction and at least one frequency domain prediction and perform a final mode decision based on rate distortion optimization (RDO) costs associated with the generated residuals. The hardware bit packing unit is to pack bits as coded according to the final mode decision into a data format.
