What does LTC mean in UNCLASSIFIED

What is Linear Time Code?

LTC is a digital code of varying length that is sent along with an audio signal over transmission lines. Its purpose is to provide precise timing information between multiple devices such as cameras and sound recorders used in television and film production or multi-track recording studios. It accomplishes this by sending unique numbers at specific intervals (typically once every frame of video) that can be read out by compatible devices; these numbers act like a “time stamp” for each frame of filming or recording event. This allows devices to maintain precise sync with one another even when separated over large distances or long periods of time.

In the television industry particularly, LTC has become the industry standard due to its accuracy and convenience in ensuring that various elements are perfectly synced when presented on-air. By using one source code stream, producers can avoid having to manually sync up elements prior to broadcast; instead they can simply rely on their equipment accurately interpreting the stream as desired.

How Does it Work?

To generate an LTC signal, a special encoder must first be used which then translates data into bits representing individual frames (plus optional additional metadata). The encoder then sends these bits over AES3 digital audio channels via either copper cable or fiber optic cabling — whichever method will provide the most efficient transfer rate. The receiving device then interprets the signal and converts it back into readable codes which can then be utilized by compatible equipment in order to achieve precise syncing tasks. The advantage here lies in not needing any separate sync wires since all required data is packaged within the one signal stream making setup simpler and faster than ever before.
