4.4.4.4 Time to live (TTL)
Why used
The TTL (Time to live) is a countdown time-out used to prevent subtitles from being left on the screen
through loss of communication.
The server or touch panel will continuously ask for the subtitle status. As long as the ’time to live’ counter
has not been expired and the subtitle status command is executed, this TTL value will be reset to its
original value set in the TTL interface.
If the TTL value reaches ’0’, the system will disable the subtitle function and the subtitling will be removed
from the screen.
How to set up
1. Tip into the TTL input field and select the current value. Change that value by entering the new value
with the digit keys on the keyboard (the value must be in seconds)
Or,
tip on the up down control of the spin box next to the TTL input field to change the value to the desired
one. (image 4-33)
