DESCRIPTION
The GS1511 HDTV Serial Digital Formatter formats the
HDTV Luma and Chroma data according to SMPTE 292M
prior to serialization by the GS1522 HDTV Serializer. The
GS1511 optionally inserts TRS and line number signals
based on externally supplied H, V and F signals. The
device also allows the insertion of CRCs based on TRS
signals embedded in the input data streams, should the
user choose not to supply external HVF signals.
Following the insertion of TRS, Line Number, and CRC,
protected words of 000-003 and 3FC to 3FF occurring
during the active video period are optionally re-mapped to
004 and 3FB respectively. Prior to exiting the device SMPTE
292M compliant NRZ(I) encoding and scrambling may be
performed on the data stream.
