Ancillary Data; Ancillary Data In Hdsdi/Sdsdi Signals; Ancillary Data In Mxf Files - Sony PDW-HD1550 Operation Manual

Ancillary Data

This unit can play and record ancillary data superimposed
on the HDSDI signals. It can also input and output
ancillary data in MXF files when transferring files via
FTP/CIFS connections. Transferable auxiliary data
includes text data (captions and metadata) and control
signals.
Ancillary data in HDSDI/SDSDI
signals
This unit can record and play back closed captions
conforming to the EIA-708-B
1)
B standard, and text data conforming to the ARIB TR
2)
B-23 standard which comprise the VANC (Vertical
ancillary data) packets.
1) EIA: Electronic Industries Alliance
2) ARIB: Association of Radio Industries and Businesses
To record ancillary data
Set the lines where ancillary data is inserted, the DID (Data
Identifier word), and the SDID (Secondary Data Identifier
word) with maintenance menu item M3B VANC RX
PARAMETER.
For details, see maintenance menu item M3B (page 106).
To record and play back auxiliary data of the
specified line
Specify the line on which the auxiliary data is recorded
using maintenance menu item M3B1 and M3B2.
Auxiliary data is recorded and played back regardless of
the DID/SDID setting values.
To record and play back EIA-708-B standard
closed caption data in HDSDI signals
Configure the following settings using the sub items of
maintenance menu item M3B0 VANC RX PACKET.
Example: When specifying line 9
• LINE (line selection): 9LINE
• DID (data identifier word): 61h
• SDID (secondary data identifier word): 01h
To record EIA-608-B standard closed caption
data in HDSDI signals
Configure the following settings using the sub items of
maintenance menu item M3B0 VANC RX PACKET.
Example: When specifying line 9
• LINE (line selection): 9LINE
• DID (data identifier word): 61h
• SDID (secondary data identifier word): 02h

standard and EIA-608-
VANC packets
• The Japanese ARIB TR-B23 standard limits the number
of packets that can be superimposed on the HDSDI
signal to 4 packets per line.
• The number of VANC packets that can be recorded,
depending on the relevant maintenance menu settings, is
limited to 9 packets per frame for 50P or 59.94P mode
and 18 packets per frame for other modes.
• When VANC packets are not continuous from word 0
and there is unused area on the line, then information
about the packet position is not recorded. Packets are
output flush left.
• During input, if a parity error is detected in a VANC
packet, the packet is discarded and recorded flush left.

Ancillary data in MXF files

VANC ancillary data recorded from an HDSDI signal is
inserted to an MXF file as an ANC Frame Element
(conforming to the SMPTE436M-2006). This data can
also be recorded on the disc from an MXF file that has
been input via CIFS/FTP.
To insert ancillary data into MXF files for
output
In setup menu item 666 METADATA ITEM OUT, select
"on".
HANC/VANC packets
Detection of HANC/VANC packets
When an MXF file has been input, HANC/VANC packets
are recorded on the disc if the DATA ITEM of the head
frame is identified as ANC Frame Elements conforming to
the SMPTE436M-2006.
