Note that local time between 1:00:00 and 1:59:59 actually is repeated twice this day, first during DST
time, then clocks are turned back one hour to normal time, and the hour is repeated during standard
time and therefore this day has 25 hours (instead of 24 hours). To avoid confusion when referring to
time within this hour, it is important to tell whether it happened before of after the change back to
normal time. For further information about daylight saving time in your area consult the web page

30 Convert Mode

The 8010TM can be operated in a 25
SMPTE time code respectively) This feature would normally be used to convert time code in standards
conversion applications.
standard is converted to time code in the output video standard. The 8010TM is connected to video in
the output video standard. The hours, minutes and seconds of the output code are jam synced to the
input code. The frames run at the normal frame rate of the output video standard.
The 8010TM OFFSET register can be used to enter a frame offset to account for frame delays in the
standards converter.
The system configuration drawings below show how the system will be configured in the translate mode
of operation.
When converting from 30 Fps TO 25 Fps code, the input code must be in the Drop
Frame format. When converting from 25 Fps to 30 Fps code, the Generator DROP
FRAME mode must be set to DROP FRAME. (See section 3.4.13)
The JAM WINDOW parameter has been added to the Engineering Setup menu. This parameter is
used to ignore the natural differences between 30 Fps and 25 Fps frame numbers within the second.
The frame counting rates of 25 Fps and 30 Fps along with the natural difference between the video
rates of 29.97 and 30 Fps (taking into account the dropped frames) produce an acceptable difference
between the 25 Fps and 30 Fps frame numbers during a given second. Any difference between the
active reader's input and the generated time code output numbers (accounting for any programmed
OFFSET) will cause the generator to resynchronize to the reader in translate mode. Under normal
circumstances the factory default setting of "6" frames should be adequate.
