Abstract
Systems and methods are provided for improving the visual quality of low resolution and/or low frame rate video content displayed on large-screen displays. A video format converter may be used to process a low resolution and/or low frame rate 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. The video format converter may also determine the frame rate of a video and may increase the frame rate if the received frame rate is below a certain threshold. For 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.
