1. A method performed by a video apparatus, comprising:
- receiving compressed video content from a source;
decompressing the compressed video content to generate uncompressed video content in an internal format having a frame rate of 24 frames per second (fps) comprising progressive frames of pixel image data having an original pixel resolution;
buffering progressive frames of pixel image data in a high-capacity memory buffer supporting asynchronous random read and write access;
processing the progressive frames of pixel image data in the buffered progressive frames to perform a frame-rate conversion from 24 fps to a higher output frame rate; and
outputting a digital HDTV video signal configured to display the video content on an HDTV at the output frame rate, wherein the digital HDTV video signal is a progressive signal having a pixel resolution of at least 1920×
1080 pixels.

Abstract
A system for processing an audio/video program to output at a desired display rate includes a computer including RAM, ROM and a processor. The system has an input receiving an input video program in a first interlaced format. The computer has hardware or software functioning to: storing the input program, at least temporarily, in the first format; de-interlacing the input video program to generate a video program in a first progressive format having progressive frames, each progressive frame being derived from a respective one, and only one, of the fields in the first interlaced format; removing or repeating some of the frames of the video program in the first progressive format generating a program in a second progressive format; outputting the program in the second progressive format, wherein the display rate of the program is at least 48 frames-per-second.
