5.6 IRIG- and Time Code Section
The main functions of the Time Code Processor (TCP) are:
- IRIG-B compatible Time Code Decoder function
- Time Code Encoder – IRIG-B compatible Time Encoder function
5.6.1 Timecode Encoder/Decoder
The generated time code signal is an IRIG-B-122 compatible signal. The time code
information can be used for time-tagging and multi-channel synchronization.
On the ANET429 a freewheeling IRIG function is implemented. If no external IRIG
signal is detected, the Time Code Processor (TCP) switches automatically to the
freewheeling operation mode. If an external IRIG-B signal is detected in freewheeling
mode, the Time Tag is automatically synchronized to this external IRIG-B signal.
