Title: Apparatus and method for data signal scattering conversion
Inventor: BU LIN-KAI
IPC: H04N5/66
Filed: 2002-01-15
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method for data signal scattering conversion. SOLUTION: This apparatus is equipped with a scattering multiplexer, a digital-to-analog converter, and a scattering demultiplexer. The scattering multiplexer receives (p) digital data signals and outputs the (q)th digital data signal among the (p) digital data signals. The digital-to-analog converter converts the (q)th digital data signal from digital to analog and outputs an analog data signal. The scattering demultiplexer has (p) output terminals and is used to output the analog data signal through the (q)th output terminal. The offset voltage outputted from the digital-to-analog converter is scattered to many data lines and it becomes difficult to sense an undesirable point which has an abnormally deep or light color due to the output offset voltage.
