HMP8156 August 1997 NTSC/PAL Encoder Description The HMP8156 NTSC and PAL encoder is designed for use in systems requiring the generation of high-quality NTSC and PAL video from digital image data.
YCbCr or RGB digital video data drive the P0-P23 inputs.
Overlay inputs are processed and the data is 2x upsampled.
The Y data is optionally lowpass filtered to 5MHz and drives the Y analog output.
Cb and Cr are each lowpass filtered to 1.
3MHz, quadrature modulated, and summed.
The result drives the C analog output.
The digital Y and C data are also added together and drive the two composite analog outputs.
The YCbCr data may also be converted to RGB data to drive the DACs, allowing support for the...
