Abstract: A method for regional compositing includes compositing a plurality of video planes and at least one graphics plane. Graphics elements of the at least one graphics plane may be stored into a single graphics plane. A rectangle may be associated to one or more graphics elements of the single graphics plane. A Z-order of the plurality of video planes and the at least one graphics plane may be determined according to rectangular regions defined by rectangles associated with graphics elements of the single graphics plane. A pixel-by-pixel Z-order may be performed based on the determined Z-order of the plurality of video planes and the at least one graphics plane.

Abstract: Disclosed are various embodiments directed to transcoding a media file in parallel. A media file may be accessed, the media file comprising a bit stream expressing a series of pictures. A first random access point in the bit stream and a second random access point in the bit stream are identified. An input segment of the bit stream is generated, the input segment comprising a starting point, the starting point being the first random access point. One of a plurality of transcoders is selected to transcode the input segment for generating a corresponding output segment, each transcoder being configured to operate concurrently in parallel. The output segment is stored in a memory.

Abstract: A method and system are provided in which a video processor may select a 2D video output format or a 3D video output format. The video processor may generate composited video data by combining video data from a video source, and one or both of video data from additional video sources and graphics data from graphics source(s). The video processor may select the order in which such combination is to occur. The video data from the various video sources may comprise one or both of 2D video data and 3D video data. The graphics data from the graphics sources may comprise one or both of 2D graphics data and 3D graphics data. The video processor may perform 2D-to-3D and/or 3D-to-2D format conversion when appropriate to generate the composited video data in accordance with the selected output video format.
