-
- 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.
