Infocomm2012 basic building blocks of iptv mp v2


Published on

Get to know the building blocks for IPTV — decoders, middleware and encoders. Then, find out how it gets more complicated. For example, a grade school teacher and a broadcast engineer may both need all three blocks but while the teacher needs the simplest user interface, the broadcaster needs an interface that accesses feature settings and performance on a deeper level. Middleware is the building block that varies significantly depending on the application while a rudimentary system does not even need middleware; it only needs STBs, encoders, and a properly configured network. This session will explore customized approaches and solutions, illustrating examples of applications.

  61. 61. InfoComm Speaking Proposal from Visionary SolutionsTitle of session: Understanding the building blocks in an IPTV systemThe global move towards IPTV adoption necessitates a thorough understandingof the nuts and bolts of the technologies behind it. An IPTV system is comprisedof three main fundamental building blocks: decoders, middleware, and encoders– however, not all systems are the same. For example, a grade school teacherand a broadcast engineer may need all three blocks but while one user needsthe simplest user interface, the broadcaster needs access to feature settingsand performance on a deeper level. In a similar vein, while middleware is one ofthe building blocks, it varies significantly depending on the application where it isbeing used and how VOD, EPG, and STB controls are managed. Again, arudimentary system does not even need middleware; it only needs STBs,encoders, and a properly configured network.
  62. 62. Critical to implementing a successful IPTV system is a thorough understanding ofa rudimentary system composed of encoders, IP network, and decoders. Thisseminar will provide attendees with a thorough understanding of the basics ofconfiguring encoders and decoders in an IPTV system, outline differences andchallenges as well as approaches and solutions, and illustrate with examples ofapplications.Learning Objectives:1. Understand minimum network requirements2. Get a thorough understanding of an encoder and decoder (set-top box andsoftware player)3. Basic building blocks are understood, IPTV as a concept and practice isdemystified.4. Middleware is application specific. Integrators integrate, fit the middleware tothe customer, what is VLC?
