Abstract
An apparatus for improved rendering includes a number of processing channels to receive multiple input content sources and to process that input content. A compositor can composite processed input content to generate a composite output signal. An output adaptation block can adapt the composite output signal along with dynamic metadata for display by a display device. Each processing channel includes a statistics generator and an input adaptation block.
Claims20
An apparatus comprising:
- a plurality of processing channels arranged in parallel and configured to receive a plurality of input content to process the plurality of input content received in parallel, wherein each processing channel of the plurality of processing channels comprises a statistics generator circuit coupled to an input adaptation circuit in series, wherein for each processing channel of the plurality of processing channels:
- the respective statistics generator circuit is configured to receive the respective input content and to compute statistics based on a luma difference representation before the respective input adaptation circuit receives and processes the respective input content;
- and
- the respective input adaptation circuit is configured to adapt the respective input content to a first format based on the computed statistics, wherein the first format is a common format for all of the plurality of input content;
- a compositor circuit configured to composite the adapted input content from the input adaptation circuits of the plurality of processing channels to generate a single composite output signal;
- and
- an output adaptation circuit coupled to the compositor circuit and configured to adapt the single composite output signal to a second format,
- wherein the statistics computed by the statistics generator circuits includes a histogram,
- wherein the statistics generator circuits are separate and different from the input adaptation circuits,
- wherein the statistic generator circuits are arranged in parallel and configured to process their respective input content received in parallel, and
- wherein the input adaptation circuits are arranged in parallel and configured to process their respective input content received in parallel.

A method of improved rendering of video content, the method comprising:
- converting, using dynamic metadata, the video content to a compositing domain, wherein the converting is performed by a plurality of processing channels arranged in parallel, each processing channel of the plurality of processing channels comprising a statistics generator circuit configured to receive the respective video content and to compute statistics based on a luma difference representation and an input adaptation circuit configured to adapt the respective video content to the compositing domain based on the computed statistics;
- compositing the adapted video content from the input adaptation circuits of the plurality of processing channels to generate a single composite output signal;
- and
- adapting the single composite output signal to an output domain;
- and
- incorporating in at least one of the compositing domain or the output domain an inverse function of an anticipated display processing of the dynamic metadata,
- wherein the statistics computed by the statistics generator circuits includes a histogram,
- wherein the statistics generator circuits are separate and different from the input adaptation circuits,
- wherein the statistic generator circuits are arranged in parallel and process their respective video content received in parallel,
- wherein the input adaptation circuits are arranged in parallel and process their respective video content received in parallel, and
- wherein using the dynamic metadata comprises directly using or modifying the dynamic metadata.
