Patent ID: 6989779

Claim:
A semiconductor device, comprising: a multiplicity of DAC channels each having a DAC for a video signal, wherein at least one of said DAC channels includes means for processing said video signal, said means having a predetermined delay time; wherein said multiplicity of DAC channels include: a composite DAC channel having a DAC for a composite signal, a luminance DAC channel having a DAC for a luminance signal, and a chrominance DAC channel having a DAC for a chrominance signal, wherein said means for processing a signal is a phase inversion means provided in said chrominance DAC channel; wherein said phase inversion means is a digital phase inversion circuit; wherein said composite DAC channel is provided with means for delaying the signal of the channel by a time which corresponds to the delay time caused by said phase inversion means; wherein said composite DAC channel and chrominance DAC channel are arranged in symmetry with respect to said luminance DAC channel.
