... Philips Semiconductors Digital Video Encoder (EURO-DENC) FUNCTIONAL DESCRIPTION The digital video encoder (EURO-DENC) encodes digital luminance and colour difference signals into analog CVBS and simultaneously S-Video signals. NTSC-M, PAL B/G and SECAM standards and sub-standards are supported. Both interlaced and non-interlaced operation is possible for all standards ...

... Philips Semiconductors Digital Video Encoder (EURO-DENC) Encoder V IDEO PATH The encoder generates out and V baseband signals luminance and colour subcarrier output signals, suitable for use as CVBS or separate Y and C signals. Luminance is modified in gain and in offset (latter programmable in a certain range to enable different black level set-ups) ...

... Philips Semiconductors Digital Video Encoder (EURO-DENC) Output interface/DACs In the output interface encoded both Y and C signals are converted from digital-to-analog in 10-bit resolution. Y and C signals are also combined to a 10-bit CVBS signal. The CVBS output occurs with the same processing delay as the Y and C outputs. Absolute amplitudes at the input of the DAC for CVBS is reduced by and C DACs to make maximum use of conversion ranges ...
