There is a misconception in the broadcast space that media outlets must wait for video over IP to mature before fully embracing an audio over IP (AoIP) infrastructure, but this is not the case. AoIP technologies have been stable for some time and today can provide the flexibility, reliability, and connectivity needed to deploy audio separately from video. Before the introduction of SDI video with embedded audio, video and audio had been handled separately for years. Although embedded audio seemed like a step forward, it did not reduce lip sync issues, and associated metadata is still easily separated from the audio. Since metadata is an increasingly essential part of new audio services, this becomes a major problem.
