Multistandard video decoder with adaptive comb filter
8.6.5
Data stream coding and reference signal generation (subaddresses 84h,
85h and 93h)
As H and V reference signals are logic 1, active gate signals are generated, which frame
the transfer of the valid output data. As an alternative to the gates, H and V trigger pulses
are generated on the rising edges of the gates.
Due to the dynamic FIFO behavior of the complete scaler path, the output signal timing
has no fixed timing relationship to the real-time input video stream. So fixed propagation
delays, in terms of clock cycles, related to the analog input cannot be defined.
The data stream is accompanied by a data qualifier. Additionally invalid data cycles are
marked with code 00h.
If ITU 656 like codes are not required, they can be suppressed in the output stream.
As a further option, it is possible to provide the scaler with an external gating signal on
pin ITRDY. Thereby making it possible to hold the data output for a certain time and to get
valid output data in bursts of a guaranteed length.
The sketched reference signals and events can be mapped to the I port output pins IDQ,
IGPH, IGPV, IGP0 and IGP1. For flexible use the polarities of all the outputs can be
modified. The default polarity for the qualifier and reference signals is logic 1 (active).
Table 19
shows the relevant and supported SAV and EAV coding.
[1]
The leading byte sequence is: FFh-00h-00h.
[2]
The MSB of the SAV/EAV code byte is controlled by:
a) Scaler output data: task A
MSB = CONLH[90h[7]]; task B
MSB = CONLH[C0h[7]].
b) VBI data slicer output data: DID[5:0] 5Dh[5:0] = 3Eh
MSB = 1; DID[5:0] 5Dh[5:0] = 3Fh
MSB = 0
