1. Program Description
The Time Code Continuity Tester (TCCT) program reads SMPTE time
code at play speed (+/- 15%), and lists all continuity errors. The
time code received and the time code expected are both listed, as well
as the time of day for each error. Up to 999 errors may be stored in
one list, which may then be saved onto a disk. Both Drop and Non Drop
frame code is supported.
You must have the BCS Software Time Code Reader Interface I,
which plugs into the second mouse port. The interface has a balanced
audio input impedance of greater than 22 kilohms.
2. Starting the Program
You may start the program by double-clicking the icon in the
Workbench screen, or by typing TCCT from CLI.
3. The TCCT Screen
Once you have started the program, the TCCT screen will appear.
The screen is divided into four columns. The first column is the
error number, and has the leading zeroes suppressed. The second
column is the time code that caused the error, as received by the
Amiga. The third column is the time code that the program expected to
receive. The fourth column is the time of day that the error
occurred.
Up to fourteen errors will be displayed on the screen at one
time. Subsequent errors will cause the display to scroll up. Up to
999 errors may be listed, after that subsequent errors will be
ignored, an error message will be displayed and the computer will beep
(with audio hookup).
At the bottom of the screen is the time code display. The time
code reader is active only in Test mode.
Above the time code display is the status line. It will always
indicate the current program's status.

4. The Menus
Most of the menu commands may be initiated from the keyboard, as
indicated in the menus themselves. The menu commands are as follows:
> Test. This puts the program in Test mode. When in Test mode, the
program disables the multi-tasking capabilities of the Amiga. All
disk access by other tasks should be completed before entering Test
mode.
> New. Clears the entire list.
> Load. Loads data from the disk. Error listing can then resume from
where you left off. The list title and printer options are loaded
from the disk as well.
> Save. Saves data onto the disk. Only one data file is allowed;
this command will write over any previously saved data.
> Print. Prints the list according to the printer options.
> Quit. Same as selecting the close gadget in the upper left corner
of the window.
> Delete Last Error. Removes the last error from the list.
> Printer Options. This command displays the printer options window.
You may then change any option by pointing at it and pressing the
left mouse button. Point outside of the window and press the left
mouse button to exit.
> Change the Title. This command displays the title window. Use the
pointer to select the title gadget, then change the title to your
liking. The title gadget displays only 38 characters at one time,
but up to 78 are allowed. Press RETURN to exit.
> Audible Alarm. Select this command to turn the audible alarm on and
off. If it is on, a 1 KHz tone will briefly sound whenever an
error is detected (with audio hookup). A checkmark next to this
command indicates that it is on.

5. Detecting Errors
Errors are detected after selecting the Test function from the
menu. While reading time code, the TCCT disables the multi-tasking
capabilities of the Amiga, so you may not work on other projects at
this time.
At the start of the test, TCCT waits until it receives two
consecutive time code numbers, then it starts testing for continuity.
It does this by computing what the next time code should be, taking
Drop Frame into account, if neccessary.
If the next time code does not match what the program expects,
the error is added to the list, and the program again waits for two
consecutive time code numbers before starting the test again.
Therefore errors that occur within about four frames of each other are
ignored. Also, if the time code "wraps around" from 23:59:59:29 to
zero, an error will be detected. This is not something that you want
happening during an edit session, for example.
After the 999th error, the list buffer is full. The computer
will beep, and a red error message will appear. You must then select
NEW, LOAD or DELETE LAST EVENT to clear the error message.
