Biography: Vishy (Viswanathan Swaminathan) is currently a Principal Scientist in Adobe's Advanced Technology Labs researching next generation Video technologies. His areas of research include Video Streaming, Processing, Coding, Protection, Digital Rights Management, and Analytics. His research work has contributed towards a number of technologies in Adobe's Media delivery and DRM products. His most recent innovative work includes the guts of Adobe's HTTP Dynamic Streaming which won the 'Best Streaming Innovation of 2011' Streaming Media Readers' Choice Award. Vishy is also an active contributor in the Ultraviolet/DECE consortium. Prior to joining Adobe, Vishy was a Senior Researcher at Sun Microsystems Laboratories working on Video Server, interactive Video, next generation Head-end and DRM technologies. While at Sun, Vishy has led multiple organizations including the Technical Committee of the Internet Streaming Media Alliance from its inception till 2004 and the MPEG-J ad hoc group. In addition, Vishy received 3 ISO certificates for his contributions to MPEG Standards. He was the lead editor of the MPEG-4 Systems Standard and has contributed to multiple Standards and Specifications.
Vishy received his MS and Ph.D. in Electrical Engineering from Utah State University. He received his B.E degree from College of Engineering, Guindy, Anna University, Chennai. Vishy has authored several papers, articles, RFCs, and book chapters, has several issued patents, and has been invited to talk at multiple conferences in the area of Video Systems.
First it was streaming, then it was progressive download. Although streaming was considered dead, now we are back to streaming for video content delivery. There are so many successful video delivery services based on streaming that video streaming seems ubiquitous. While more bandwidth availability is undeniably the most significant reason, digging deeper reveals other factors too. There is a significant move towards HTTP based video streaming for entertainment content based on cost and reach. Some would even consider it a hybrid of both streaming and download. Also, there is a separation of technologies between entertainment (video on demand or live) content and real-time communications (video conferencing). Did the best technology (HTTP vs RTP or AVC vs SVC codecs) win? Would the same choices prevail for both wired and wireless networks? What about congestion control with seemingly conflicting applications? What future challenges can we expect? In this talk I will elaborate more on the reasons for the success of HTTP streaming of Video after describing the basic aspects of an HTTP Streaming system and comparing it with traditional streaming systems. I will also introduce MPEG-DASH and other prevailing Standards and technologies. I will conclude with what lessons we have learnt so far and thoughts on and how to apply them to future challenges.
