DESCRIPTION
DESCRIPTION
DESCRIPTION
DESCRIPTION
When interfaced to the Gennum GS1545 HDTV Equalizing
Receiver or GS1540 Non-Equalizing Receiver, the GS1510
performs the final conversion to word aligned data. The
device performs NRZI decoding and de-scrambling as per
SMPTE 292M and word-aligns to the incoming data stream.
Line based CRCs are calculated on the incoming data
stream and are compared against the CRCs embedded
within the data stream.
HVF timing information is extracted from the data stream. A
selectable internal HVF flywheel provides superior noise
immunity against TRS signal errors. The device also detects
and indicates the input video signal standard.
The GS1510 can detect and re-map illegal code words
contained within the active portion of the video signal. Prior
to exiting the device, TRS, Line Numbers and CRCs based
on internal calculations may be re-inserted into the data
stream.
