摘要： 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.

摘要： Systems and methods are provided for combining a plurality of streams with a plurality of formats into a single output stream in a predetermined output format. Each of the plurality of streams includes at least one of video or graphics. Each stream is processed by determining a format of the stream, determining whether the format is compatible with the predetermined output format, and responsive to determining that the format is compatible with the predetermined output format, converting the format to the predetermined output format. The processed plurality of streams are combined into a single output stream in the predetermined output format.

摘要： Systems and methods are provided to render a plurality of graphical assets each having a format of a plurality of formats. Each graphical asset is processed by determining whether the format of the graphical asset is compatible with a predetermined render domain format and responsive to determining the format is not compatible with the predetermined render domain format, converting, using a format conversion circuit, the format to the predetermined render domain format. The plurality of graphical assets are rendered using a single rendering engine operable coupled to the format conversion circuit using the predetermined render domain format.

摘要： In some aspects, the disclosure is directed to methods and systems for transformation between media formats, such as between standard dynamic range (SDR) and high dynamic range (HDR) media or between HDR media formats, without undesired hue shifting, via one or both of a luminance mapping ratio technique and a direct color component mapping technique.
