Abstract:
A video processing circuit comprises:DVD module that receives a DVD data stream and converts the DVD data stream into a video data stream and a subpicture data stream; memory that stores a frame of the video data stream and a partially decoded representation of the subpicture data stream; a videos-scaling module operably coupled to the memory, wherein the video scaling module receives at least one line of the frame of the video data stream and produces therefrom scaled video data; a subpicture scaling module operably coupled to the memory, wherein the subpicture scaling module receives at least a line of the partially decoded representation of the subpicture data stream and produces therefrom scaled subpicture data; and a blending module operably coupled to receive the scaled video data and the scaled subpicture data and to produce therefrom a video output.
