DESCRIPTION
DESCRIPTION
DESCRIPTION
The GS1501 HDTV Serial Digital Formatter formats the
HDTV Luma and Chroma data according to SMPTE 292M
prior to serialization by the GS1522 HDTV Serializer. The
GS1501 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. In addition, ANC data may be
inserted into the video stream through an internal FIFO
interface. Prior to exiting the device SMPTE 292M compliant
NRZ(I) encoding and scrambling may be performed on the
data stream.
