1. OVERVIEW
The HD9010TM-IRIG HDTV Time Code Master with IRIG-B Reader is a full function time code
reader/generator system for SMPTE 292M (1.5 Gb/s) high definition serial digital video. The HD9010TM-
IRIG is a combination generator/reader for SMPTE 12M Linear Time Code (LTC) and SMPTE RP188
Ancillary Time Code (ATC), a reader for IRIG-B code, and a generator/reader of Vertical Ancillary Data
(VANC) packets containing the IRIG-B code. The HD9010TM also contains a high resolution character
inserter that can burn the generator or reader numbers directly into the serial digital program output.
The HD9010TM-IRIG reads IRIG-B code commonly in use within the United States government agencies
and supporting private industries and provides a display of days, hours, minutes, seconds and
milliseconds in the character inserter. This IRIG information is inserted into a special ancillary data packet
in the vertical ancillary data space (VANC) of the SMPTE 292M serial bitstream. This special VANC
packet can be decoded by the HD9010TM-IRIG’s VANC reader to allow you to encode the IRIG
information onto a ‘clean’ videotape and then display the IRIG information later on playback.
The HD9010TM-IRIG SMPTE Time code generator is output as LTC and ATC and can also be slaved to
incoming IRIG serial time code. The millisecond count will be converted to the closest frame number and
can also be stored in the generator user bits along with the IRIG day of the year. In the continuous jam
sync mode, the generator is slaved to the IRIG-B reader, and will follow code any discontinuities of the
reader. The generator may also be momentarily synchronized to the IRIG-B reader, and then it continues
to increment normally regardless of the reader code. Momentary jam is the recommended mode when
synchronizing to IRIG-B sources so that the resulting SMPTE time code does not contain discontinuities
due to the different time bases of 29.97 frames per second video and real time of the IRIG code. In NTSC
related video systems, the SMPTE generator should be operated in the Drop Frame counting mode when
trying to synchronies the SMPTE generator to IRIG.
The HD9010TM-IRIG SMPTE Time code generator can also be slaved to incoming LTC or ATC, or can be
set to free run. The generator may also be momentarily synchronized to one of the readers, and then
continue to increment normally regardless of the reader code. The second LTC output normally follows
the primary output, however the two generators can be operated at different frame rates to supply both
24Fps and 30Fps time code when shooting in a 1080p/24 environment.
The high-resolution character inserter provides independently positionable windows to show time and user
bits for the SMPTE generator and readers simultaneously. When the IRIG or VANC readers are operating
in the IRIG DAY mode, there are two independently positionable windows for each reader to show the
IRIG time to millisecond precision and the IRIG day respectively. The character font is 30 video lines high
and 44 pixels wide per character. The choice of white or black characters with or without contrasting
background mask is available.
