CONVERT 25
⇔
30:
Sets the 5010 or 5010-VITC into a SMPTE
⇔
EBU timecode translator mode.
This mode is used to convert timecode in standard converter applications. In
translate mode incoming LTC of the input video standard is converted to
timecode of the output video standard. The generator time is compared to the
LTC reader time. When the two times disagree by more than the
CONVERT WINDOW parameter, the Generator time is jammed from the reader
time, taking into account the frame numbering differences of SMPTE and EBU
code. The frames run at the normal frame rate of the output video standard. The
JAM LED will come on each time the Generator resynchronizes to the Reader. A
jam sync offset can be set using the method outlined in section 4.5.8. For
information about using the Convert mode with models 5010-24 and
5010-VITC-24 see section 4.10.3.
"
When translating from SMPTE to EBU code, the input code must be in the Drop
Frame format. When translating from EBU to SMPTE code, the Generator DROP
FRAME mode must be set to DROP FRAME. (See section 4.5.11)
4.5.2. Configuring the Date Format
The
DATE FORMAT
menu item is used to select the format of the date information in the user bits of
the generator and reader.
YY MM DD:
Configures the user bits for date encoding in
TT YY MM DD
format. This mode
is designed so that simple time code readers can display the BCD encoded date
information in numeric format.
TT
is a time zone offset to be applied to the Hours of the time.
YY
is the year in BCD format.
When YY is less than 50 the year will be displayed as 20YY.
(i.e. when YY=01 the year will be displayed as 2001).
When YY is greater than 50 the year will be displayed as 19YY.
(i.e. when YY=95 the year will be displayed as 1995).
MM
is the month of the year.
DD
is the day of the month.
For example: the date August 15, 1994 (no time zone offset) will be encoded in
the user bits as 00 94 08 15.
MODIFIED JULIAN:
Configures the user bits for date encoding in TT dddddd format. This mode
should be used when the complete date including century is required. Simple
readers will not be able to decode this format.
TT is a time zone offset to be applied to the Hours of the time ddddd is a 24 bit
binary number representing the modified Julian date.
