    Abstract: Techniques related to selecting restoration filter coefficients for 2-dimensional loop restoration filters for super resolution video coding are discussed. Such techniques include upscaling reconstructed video frames along only a first dimension and selecting filter coefficients for portions of the frame by an evaluation that, for each pixel of the portion, uses only pixel values that are aligned with the first dimension. Selection of filter coefficients for the second dimension may be skipped or made using only a subset of available filter coefficients.

    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.
