What critical function does a TSC perform during a video conferencing session?

A Tactical Session Controller (TSC) plays a vital role in maintaining the quality and stability of media streams during a video conferencing session. This function is crucial because video conferencing relies on high-quality audio and video to ensure effective communication between participants. The TSC manages network resources efficiently, optimizes the distribution of media packets, adjusts to varying bandwidth conditions, and handles encoding and decoding tasks to ensure that the media streams remain smooth and uninterrupted.

By monitoring and adjusting the performance of the streams in real-time, the TSC can mitigate issues such as latency, jitter, and packet loss, all of which can significantly impact the user experience. This quality control ensures that participants can engage in productive discussions without being hindered by technical difficulties.

While other roles mentioned are significant in the broader context of video conferencing technology, they do not directly pertain to the immediate task of ensuring stream quality and stability during an active session. Therefore, focusing on media stream management highlights the TSC's primary and critical function in facilitating effective communication.
