What does "real-time" communication entail?

Real-time communication refers to interactions that happen simultaneously, allowing parties to engage in a conversation as it unfolds. This typically involves immediate feedback where both parties can see and hear one another without interruptions. In the context of audio-video interaction, it emphasizes the capability for live discussions, fostering a fluid exchange of ideas and information.

In contrast, communication with significant delays would fail to enable this instant engagement, making it not qualify as real-time. Similarly, communication that occurs in person only restricts the definition by excluding other valid forms such as video calls or instant messaging that can also happen in real-time. Lastly, pre-recorded communication distinctly lacks the immediacy and interactive quality required for real-time exchanges, as it does not allow for spontaneous responses. Therefore, the essence of real-time communication is captured well by the notion of simultaneous audio-video interaction without interruptions.
