Other processing functions include H:V:F timing extraction,
Y and C ancillary data indication and video standard
indication.
The device may also be used in data pass through mode
where no processing of the data is performed.
Parallel data outputs are provided in both 10 bit multiplexed
and 20 bit de-multiplexed format for HD and SD signal
rates. An associated parallel clock output signal is provided
operating at 148.5 or 148.5 / 1.001 MHz (HDTV 10 bit
multiplexed output), 74.25 / 74.25 / 1.001 MHz (HDTV 20 bit
de-multiplexed output), 27 MHz (SD 10 bit multiplexed and
DVB-ASI output) and 13.5 MHz (SD 20 bit de-multiplexed
output).
The parallel clock output, is provided in TTL compatible and
differential forms (BGA package only) and TTL compatible
forms.
Additional capabilities such as DVB-ASI decoding, SMPTE
352M payload identifier packet decoding and EDH
processing are also provided by the device.
The device will detect the presence of DVB ASI sync words
and will automatically switch into bypass mode. The DVB
ASI data will be word aligned to K28.5 sync characters and
8b/10b decoding is applied to the received data stream.
EDH FF and AP CRC calculation and comparison is
performed. Error flags are generated based on these CRC
comparisons. Re-calculated CRC's may be inserted into the
output data stream.
Line number generation is also performed by the device,
and for HDTV interfaces, the line number may be inserted
into the output data stream.
As well as detecting and extracting SMPTE 352M payload
identifier packets, the GS1560 can also automatically
identify the received video standard and the payload data
type. The detected video standard and data format may be
read via the host interface port.
