Abstract: This article presents a study of a letter-box method for wide-aspect TV; top and bottom bars are used for improving vertical-temporal resolution. The authors propose a new method for separating and combining augmentation signals, in which block processing using a matrix operation is adopted and original proscanned images can be completely reproduced at receivers. The new method is implemented in basic hardware. As a result, the augmentation signals allow proscanned images to be completely recovered in wide TV receivers without significant aliasing occurring in current receivers. Even if the signals have only low-frequency components, dynamic characteristics are sufficiently improved.
