Recent shifts in video network architectures promise to impact the videoconferencing world in a powerful way. While IP remains the core transport medium and H.264 remains the video algorithm of choice, interest in a switched infrastructure is coming back, but with several new twists.
Andrew Davis and I published a new paper (Wainhouse Research Note) on the impact of new video architectures on the market place. We compared traditional transcoding with layer switching and stream switching technologies.
