Product specification
Digital multistandard colour decoder with
SCART interface (DMSD2-SCART)
SAA7151B
Signal levels
(Figures 12, 13 and 14)
The nominal input and output signal levels are defined by a colour bar signal with 75 % colour, 100 % saturation and
100 % luminance amplitude (EBU colour bar).
CUV-bus input format
The CUV-bus transfers the digital chrominance/colour-difference signals from the ADC to the SAA7151B (Fig.6; Table 1):
normal mode for digital chrominance transmission.
UV colour-difference mode for colour-difference signals UV (out of matrixed RGB signals)
FS mode (fast switch mode; UV inserted into chrominance signal C with addition of the two signal spectra).
RTCO output
The RTCO output signal (Fig.10) contains serialized information about actual clock frequency, subcarrier frequency and
PAL/SECAM sequence. This signal may preferably be used with the frequency-locked digital video encoder SAA7199B.
