What does session description protocol (SDP) help with in TSC operation?

Session Description Protocol (SDP) is a format used for describing multimedia communication sessions in a way that facilitates proper configuration and compatibility of media streams. In the context of Tactical Session Controller (TSC) operation, SDP is crucial for ensuring that the audio, video, and other media components can be properly understood and utilized by all participating entities in a session.

Specifically, SDP provides information about the media types, codecs, formats, and network details necessary for establishing and maintaining a media stream. It enables devices to negotiate the characteristics of the communication sessions and helps in dynamically configuring media parameters to ensure seamless interaction among various endpoints. This aligns perfectly with the option regarding configuration and compatibility, making it the correct answer.
