Abstract:
1. An adaptive multi-function display controller arranged to receive an incoming video stream having an associated native video format from a video source and provide an outgoing video stream for display by a display unit at a display format, comprising: a video source converter unit for ascertaining the native video format, detecting if the incoming video stream is an interlaced video stream, and converting the incoming video stream to a common video format suitable for subsequent video processing by the controller; a comparator unit connected to the display and the source converter for comparing a set of display characteristics and the native video format and generating a downscaler enable signal based upon the comparison; a film source detector unit coupled to the video source converter unit arranged to determine if the input video stream is a film originated video stream; a de-interlace unit coupled to the film source detector unit for de-interlacing the input video stream, if needed, to form a progressive scan video stream; a multimode frame rate converter unit coupled to the de-interlace unit for converting the progressive scan video stream at a native frame rate to the display frame rate using motion compensated frame rate conversion by itself or in conjunction with any of a number of selectable other frame rate conversion modes; and an adaptive scaler unit arranged to scale the input video stream as required for display on the display unit following a scaling protocol based, in part, upon a native resolution of the incoming video stream and the display resolution.
