Video signal processing device

摘要

A video signal processing device of the invention includes an IP conversion means for converting an interlaced video signal that has been input into a progressive video signal and outputting it, a synthesis means for synthesizing the progressive video signal and a sub-picture or OSD that has been input and outputting the result as a progressive video signal, and a PI conversion means for converting the progressive video signal into an interlaced video signal and outputting it. The progressive video signal and the interlaced video signal are both output. Thus, the picture quality of synthetic sub-pictures or OSDs is not deteriorated and the progressive video signal and the interlaced video signal can be output simultaneously.
