Title: Vertical filter circuit
Inventor: ONODERA JUNICHI
IPC: H04N7/00
Filed: 1990-10-23
Abstract: PURPOSE:To display a high definition picture on a screen for reproducing NTSC signals at the same aspect ratio by fully utilizing the lateral dimension of the screen by converting the signals into signals for NTSC non-interlace by compressing the signals to 3/4 and compressing the horizontal time base at the compression rate. CONSTITUTION:Of the 1,125 scanning lines of one frame of high-definition MUSE signals, the 516 luminance signal scanning lines in one field of 6OHz/sec are converted into 387 lines by converting each 4 lines of the 516 luminous signal scanning lines into 3 lines. Thus signals for NTSC interlace having a frame number of 60/sec are obtained with the 387 scanning lines. Since the number of effective scanning lines of the signals for NTSC interface is 483 and the difference between the 483 lines and 387 lines becomes a blank section where no video signal exists, but the horizontal time base is also compressed to 3/4 by superimposing DC components upon the blank section, and so forth. Therefore, a high definition picture can be displayed on a screen for reproducing NTSC signals at the same aspect ratio of 9:16 by fully utilizing the lateral dimension of the screen.
