Methods and systems for improving low-resolution video
View Patent ↗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.
1. 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.
2. The method of claim 1 , wherein processing the received video signal comprises deinterlacing the received video signal using the selected deinterlacing technique.
3. The method of claim 1 further comprising:
reducing artifacts in the received video signal; and
enhancing the received video signal.
4. The method of claim 1 further comprising:
scaling the received video signal to a second resolution based on the actual resolution, wherein the second resolution corresponds to a resolution of the video display; and
displaying the scaled video signal on the video display.
5. The method of claim 4 , wherein scaling the received video signal comprises:
converting the received video signal to a video signal with the actual resolution; and
scaling the converted video signal to a video signal with the second resolution.
6. 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.
7. The method of claim 6 , wherein processing the received video signal comprises reducing artifacts in the received video signal using the selected noise reduction technique.
8. The method of claim 6 , further comprising deinterlacing the received video signal.
9. The method of claim 6 further comprising:
scaling the received video signal to a second resolution based on the actual resolution, wherein the second resolution corresponds to a resolution of the video display; and
displaying the scaled video signal on the video display.
10. The method of claim 9 , wherein scaling the received video signal comprises:
converting the received video signal to a video signal with the actual resolution; and
scaling the converted video signal to a video signal with the second resolution.
11. A system for processing video content for display on a video display, the system comprising:

scale the received video signal to a second resolution based on the actual resolution, wherein the second resolution corresponds to a resolution of the video display; and
display the scaled video signal on the video display.
15. The system of claim 11 , wherein the processing circuitry is further configured to:
convert the received video signal to a video signal with the actual resolution; and
scale the converted video signal to a video signal with a second resolution, wherein the second resolution corresponds to a resolution of the video display.
16. 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 noise reduction techniques based on the actual resolution and to process the received video signal.
17. The system of claim 16 , wherein the processing circuitry is further configured to reduce artifacts in the received video signal using the selected noise reduction technique.
18. The system of claim 16 , wherein the processing circuitry is further configured to deinterlace the received video signal.
