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.
