Abstract

The Studio-to-Transmitter Link (STL) is a critical subsystem within the Advanced Television Systems Committee
(ATSC) 3.0 broadcasting architecture, serving as the bridge between studio originated content and the physical transmission
infrastructure. It handles the encapsulation, timing, synchronization, and reliable delivery of essential data streams, including
Baseband Packets (BBPs), Preamble information, and Timing and Management (T&M) data from the Broadcast Gateway to
one or more transmitters. To support robust and synchronized emissions, the STL employs transport protocols derived from the
Common Tunneling Protocol (CTP), like Data Source Transport Protocol (DSTP), ATSC Link-Layer Protocol Transport Protocol
(ALPTP) and Studio-to-Transmitter Link Transport Protocol (STLTP), these protocols ensure that data is delivered in the correct order and at the correct time, even across complex networks.
