Title:
TELEVISION SIGNAL GENERATING DEVICE
Document Type and Number:
Japanese Patent JPS63161794
Kind Code:
A
Abstract:
PURPOSE:To completely digitize by reading out reference sine wave digital data stored in a memory by shifting an address each one line and executing the offset of a subcarrier. CONSTITUTION:A titled device equips the memory 1-memory 3 which store the reference sine wave digital data, a means for reading out the data in the memory 1-memory 3 by shifting the address every line, a multiplier 1 and a multiplier 2(multiplication means) which multiply color difference signal digital data by the output data from the memory 1-memory 3 and an adder 3 and an adder 4 which add the output from the multiplication means to luminance signal digital data. And with reading out the sine wave data, by which the color difference signal data is multiplied, in clocks which are integral times as many frequencies as the luminance signal, the contents of the data is made to be altered little by little. Thus, both luminance signal and chrominance signal can be constituted with the complete digital data.
