Education and outreach

“IPTV” is another way to move, switch, androute video

Sometimes it’s the best way

Instead of expensive satellites for back-haul

To replace failing coaxial infrastructure

In new construction - avoid duplicate infrastructures

The data network is already in place

Use IPTV

Extra Credit !BYOD !

HLS !

Android devices need “MXPlayer”

Iphone and ipad devices are “good to go”

Your smart phone is a decoder too

decode a 300kbit stream being served up from the “cloud” via 3G and 4G

Androids – “MXPlayer” @ market or “play store” The next slide shows an HLS stream address Prepare to enter it into the browser address box Ready?

Thank you.

Hybrids, TS, HLS and unicast tunneling Managed LAN verses Unmanaged WAN and

WiFi

Multicast Transport Stream on the LAN,

HLS everywhere else

Use both architectures for ubiquitous distribution

Hybrid models, “tunneling”

What do I do if a channel is out? Verify that video source is on Verify that encoder is streaming – Web

InfoComm Speaking Proposal from Visionary Solutions Title of session: Understanding the building blocks in an IPTV system  The global move towards IPTV adoption necessitates a thorough understanding of the nuts and bolts of the technologies behind it. An IPTV system is comprised of three main fundamental building blocks: decoders, middleware, and encoders – however, not all systems are the same. For example, a grade school teacher and a broadcast engineer may need all three blocks but while one user needs the simplest user interface, the broadcaster needs access to feature settings and performance on a deeper level. In a similar vein, while middleware is one of the building blocks, it varies significantly depending on the application where it is being used and how VOD, EPG, and STB controls are managed. Again, a rudimentary system does not even need middleware; it only needs STBs, encoders, and a properly configured network.  

Critical to implementing a successful IPTV system is a thorough understanding of a rudimentary system composed of encoders, IP network, and decoders. This seminar will provide attendees with a thorough understanding of the basics of configuring encoders and decoders in an IPTV system, outline differences and challenges as well as approaches and solutions, and illustrate with examples of applications.  Learning Objectives:1. Understand minimum network requirements2. Get a thorough understanding of an encoder and decoder (set-top box and software player)3. Basic building blocks are understood, IPTV as a concept and practice is demystified. 4. Middleware is application specific. Integrators integrate, fit the middleware to the customer, what is VLC?
