 ncing? - Henning Schulzrinne\, Columbia University

DESCRIPTION:Video conferencing has been around since the 1990s\, first bas
 ed on ISDN for digital phone systems\, then H.323\, and then SIP for the I
 nternet. The underlying assumption was that phone calls and group communic
 ations would all rely on the same standards\, creating a universal and sea
 mless user experience.  But even as COVID-19 made Zoom a generic term\, th
 ese standards-based solutions never got much traction. Even for the popula
 r applications\, WebRTC seems to have made modest inroads.  In this talk\,
  I'll try to reflect on the reasons for this development\, and why other s
 tandards-based internet applications such as web browsers and email have b
 een more successful. Video conferencing also shares this "fate" with text-
 based chat\, where standards-based solutions are competing with WhatsApp\,
  Slack and other proprietary platforms. I believe that transition from (ro
 om) hardware to downloadable software\, control protocol complexity\, indu
 stry structure and communication patterns are at least partial explanation
 s for this development. Finally\, I will speculate on how video interactio
 n might evolve in the next few years.\n\nBio: Henning Schulzrinne was the 
 Chief Technology Officer (CTO) for the United States Federal Communication
 s Commission\, having been appointed to that role on December 19\, 2011 to
  2014.Previously he was chair and Julian Clarence Levi Professor of the Co
 mputer Science department at Columbia University. He is a co-chair of the 
 Internet Technical Committee of the IEEE Communications Society.\n\nSchulz
 rinne studied engineering management at the Department of Electrical Engin
 eering and Information Technology of the German Technische Universität Da
 rmstadt in Darmstadt\, where he earned his Vordiplom (cf. Diplom)\, then w
 ent on to earn his M.Sc. at the University of Cincinnati and his Ph.D. at 
 the University of Massachusetts Amherst.\n\nSchulzrinne has contributed to
  standards. He co-designed the Session Initiation Protocol along with Mark
  Handley\, the Real Time Streaming Protocol\, the Real-time Transport Prot
 ocol\, the General Internet Signaling Transport Protocol\, part of the Nex
 t Steps in Signaling protocol suite. He was elected as an ACM Fellow (2014
 ) for contributions to the design of protocols\, applications\, and algori
 thms for Internet multimedia.\n
