3.4.1. Configuring the Generator Mode
GEN MODE
Gmode: time data
Gmode: time rtime
Gmode: time rub
Gmode: time rctl
OPERATION
HD9010TM-IRIG HDTV Time Code Master / IRIG-B Reader Manual
The GEN MODE menu item is used to select the type of information
that is contained in the time and user bits of the generator. When the
HD9010TM-IRIG is not in the Continuous Jam Sync mode, the
generator Time bits contain time information entered from the front
panel.
When the HD9010TM-IRIG is in the Continuous Jam Sync
mode, the time bits are slaved to the primary reader's time.
Gmode: Time Data configures the user bits for entering numeric data
entered from the front panel.
Gmode: Time Rtime transfers the primary reader's time bits to the
generator user bits. (See section 3.5.1 for information on selecting the
primary reader) Transferring reader time is useful when you want to
record new continuous time code numbers and still retain the original
time code numbers for future reference.
Gmode: Time Rub transfers the primary reader's user bits to the
generator time bits. (See section 3.5.1 for information on selecting the
primary reader) Transferring the reader user bits is used when reader
time data previously transferred to user bits as above, or other user bit
information must be retained when recording new code. When used in
conjunction with the Continuous Jam Sync mode, both the time and
user bits will be transferred to the new tape.
When you want to transfer the IRIG time and day information to the
SMPTE Generator, then set the Gen Mode to Time Rub and set the
Primary Reader to IRIG. Then when you perform a momentary or
continuous jam sync, the IRIG time and day will be transferred to the
SMPTE generator time and user bits. Note that when you are using a
29.97 or 59.94 FPS video format you should also set the GEN DROP
FRAME to Drop Frame On.
Gmode: Time rctl sets the HD9010TM-IRIG into a user bit remote
control mode. In this mode six of the input pins on the parallel remote
control port are used to control the setting of the six remote control user
bits. When the 7721DD4-HD+GPI decoder module reads the RP188
ancillary time code, these encoded user bits directly control six contact
closure outputs. When the HD9010TM-IRIG is placed into the TIME
RCTL mode, special binary group flags are set, signalling the remote
control mode to the decoder. This allows an extra level of security at
the decoder and ensures that random user bit patterns do not
inadvertently activate the contact closure outputs of the decoder.
When the user selects the remote control mode, the generator user bits
will be set to
XX 80 80 93
Where the value of XX depends on the states of the remote control
input pins. See Table 3-5.
