第１項記載の同期信号圧縮分離回路。[Claims for Utility Model Registration] 1. In a digital television, a Y/C separation circuit that separates a composite color television signal into a luminance signal and a color signal after A/D conversion, and a luminance signal from the Y/C separation circuit. A circuit that inputs the synchronization signal and fixes it to a single level, and a circuit that fixes the synchronization signal to a single level.The output from the circuit that fixes the synchronization signal to a single level is subjected to various signal processing such as edge enhancement and scanning line conversion, or A synchronization signal compression and separation circuit comprising: a synchronization separation circuit that extracts the synchronization signal fixed to the single level during processing. 2. The circuit for fixing the synchronization signal to a single level assigns a quantization level from 1 to a maximum quantization level to the effective range of the luminance signal, and assigns a quantization level of zero to the synchronization signal. 1. A synchronizing signal compression/separation circuit as set forth in Paragraph 1 of the utility model registration claim.
