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 GS1501 SMPTE 292M compliant NRZ(I) encoding and scrambling may be performed on the data stream.
