Abstract
Systems and methods are provided for improving the visual quality of low-resolution video displayed on large-screen displays. A video format converter may be used to process a low-resolution video signal from a media providing device before the video is displayed. The video format converter may detect the true resolution of the video and deinterlace the video signal accordingly. For low-resolution videos that are also low in quality, the video format converter may reduce compression artifacts and apply techniques to enhance the appearance of the video.
Claims20
A method of processing video content for display on a video display, the method comprising:
- receiving a video signal having a received resolution;
- detecting an actual resolution of the received video signal, wherein the actual resolution differs from the received resolution;
- and
- processing the received video signal, wherein the processing comprises selecting an appropriate one of a plurality of deinterlacing techniques based on the actual resolution.
A method of processing video content for display on a video display, the method comprising:
- receiving a video signal having a received resolution;
- detecting an actual resolution of the received video signal, wherein the actual resolution differs from the received resolution;
- and
- processing the received video signal, wherein the processing comprises selecting an appropriate one of a plurality of noise reduction techniques based on the actual resolution.
A system for processing video content for display on a video display, the system comprising:
- a receiver configured to receive a video signal having a received resolution;
- detection circuitry configured to detect an actual resolution of the received video signal, wherein the actual resolution differs from the received resolution;
- and
- processing circuitry configured to select an appropriate one of a plurality of deinterlacing techniques based on the actual resolution and to process the received video signal.
