Abstract:
A method of improving the perceptual video quality of video sequences containing black bars. Horizontal or vertical black bars caused by a missmatch between the aspect ratio of the encoded video and the display device. The presence of black bars is detected, and the encoding process is adjusted to eliminate visual depredation of the reproduced video.
