  • Double scanning circuit of ID-TV
    Patent number: 5115312
    Abstract: A double scanning circuit of improved definition TV (ID-TV) capable for improving resolution of screen and excluding raster by scanning the color signal or the luminance signal of the original signal and the color signal or the luminance signal of the interpolation signal by double speed sequentially. The invention relates to inputting an original signal S1 and an interpolation signal S2 of 8 bits to the line memories through 3-state buffer circuit blocks and 3-state transceiver circuit blocks, and an original signal S1 and an interpolation signal S2 are inputted in said line memories and outputted alternately through a multiplexer, so that double scanning is realized. The present invention provides the effects of doubling the resolution of the screen and also excluding the raster of screen.
