Ancillary Data This unit can play and record ancillary data multiplexed into HDSDI signals. It can also input and output ancillary data in MXF files when transferring files via FAM or FTP connections. Transferable auxiliary data includes text data (captions and metadata) and control signals. Ancillary data in HDSDI signals This unit can record and play back closed captions conforming to the EIA-708-B 1) standard and text data conforming to the ARIB TRB23 2) 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 In maintenance menu item M3B: VANC RX PARAMETER, set the lines where ancillary data is inserted, the DID (Data Identifier word), and the SDID (Secondary Data Identifier word) (see page 146). To record EIA-608-B standard closed caption signals in SDSDI signals after conversion to the EIA-708-B standard Set the following items. • Sub items of maintenance menu item M3B: VANC RX PARAMETER - DID (data identification word): 61h - SDID (secondary data identification word): 01h • V INPUT on function menu page P1 VIDEO: SDSDI • Setup menu item 031 RECORDING FORMAT: HD422, 420HQ, or 420SP Ancillary data in MXF files VANC ancillary data recorded from a HDSDI signal can be inserted to an MXF file as an ANC Frame Element (conforming to the SMPTE436M-2006) and can be output. This data can also be input and recorded on the disc. To insert ancillary data into MXF files to output In setup menu item 666 METADATA ITEM OUT, select "on" (see page 135). HANC/VANC packets Detection of HANC/VANC packets HANC/VANC packets are recorded on the disc only when the DATA ITEM of the head frame is identified as ANC Frame Elements conforming to the SMPTE436M-2006 when an MXF file is input. General MXF metadata This unit examines the data contained in the header metadata area 1) when an MXF file is input. If the data is identified as the data created by the device other than XDCAM at this time, one file (KLVE file) is created. 1) The header metadata area contains the metadata information about the entire file. See SMPTE377M for details. For details, see "Directory structure" (page 104) and "Clip directory" (page 106). VANC packets • The Japanese ARIB TR-B23 standard limits the number of packets that can be multiplexed into HDSDI to 4 packets per line. • The number of VANC packets that can be recorded that is set using maintenance menu item M3B 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. Appendix 173 Ancillary Data
