The luma component is derived from the composite signal by subtracting the remodulated chroma
information. A line delay exists in this path to compensate for the line delay in the adaptive comb filter in
the color processing chain. The luma information is then fed into the peaking circuit, which enhances the
high frequency components of the signal, thus improving sharpness.
For NTSC/PAL formats, the color processing begins with a quadrature demodulator. The Cb/Cr signals
then pass through the gain control stage for chroma saturation adjustment. An adaptive comb filter is
applied to the demodulated signals to separate chrominance and eliminate cross-chrominance artifacts.
An automatic color killer circuit is also included in this block. The color killer suppresses the chroma
processing when the color burst of the video signal is weak or not present. The SECAM standard is similar
to PAL except for the modulation of color, which is FM instead of QAM.
The timing processor is a combination of hardware and software running in the internal microprocessor
that serves to control horizontal lock to the input sync pulse edge, AGC and offset adjustment in the
analog front end, vertical sync detection, and Macrovision detection.
The TVP5150AM1 VDP slices various data services such as teletext (WST, NABTS), closed caption (CC),
wide screen signaling (WSS), etc. These services are acquired by programming the VDP to enable
standards in the VBI. The results are stored in a FIFO and/or registers. The teletext results are stored only
in a FIFO. Table 3-1 lists a summary of the types of VBI data supported according to the video standard. It
supports ITU-R BT. 601 sampling for each.
