IPTV for People who AREN’T Engineers by Shaun Carlson Arvig
How a most Network Engineers feel when teaching the “non-technically inclined” … and how the “non-technically inclined” feel when listening …
Alternate Title: “How to talk to a Network Engineer”
What to expect from this presentation Don’t expect: to build an IPTV network in your home a network engineer to ask you to fix the DHCP server because STB client leases are overloading the network to shout out the textbook definition to Protocol Independent Multicasting (PIM) on command DO expect: to have basic familiarity with what an IPTV system involves to better appreciate the technical jargon used by your engineering team a network engineer to be annoyed by all of your new questions after this session
What is IPTV? One Definition: Internet Protocol television (IPTV) is a system through which television services are delivered using the Internet protocol suite over a packet-switched network such as the Internet, instead of being delivered through traditional terrestrial, satellite signal, and cable television formats. ITU-T Definition: IPTV is defined as multimedia services such as television/video/audio/text/graphics/data delivered over IP based networks managed to provide the required level of quality of service and experience, security, interactivity and reliability. Alternate Definition: IPTV is another way of getting television to the house using a method very similar to delivery of Internet to the home.
Some Terms You Might Hear… Multicast Unicast DHCP IGMP PIM Jitter Latency Middleware Encoder Transcoder Set Top Box Residential Gateway (RG) Router Switch Quality of Service (QoS) Quality of Experience (QoE) VLAN Transport MPEG 2/4 Buffer Bandwidth Video on Demand (VoD) Tiling Guide Data IP Address Audio/Video PID Routing Protocols
Let’s break it down (30,000 ft. view) Home Head End Transport Network Access Network
Head End What does a Head End Do??? * Not a real head end… (I hope) Simply put, it provides the video to the network So… how does it do that exactly? Satellite Dishes IP Feeds Encoders Transcoders MPEG 2/4 Middleware Servers This is where Multicast Originates! Wait… what the heck is Multicast???
Transport Network Ok, I get the Head End Now… kinda… and what did you say a transport network is? I’ve got the whole world, in my hands… Basically, it’s how we move the video (TV Signal) from the Head End to the rest of the world, or in this case customer hand off point How important is the transport network? Well… the transport network can have a HUGE impact on the quality of the video and what the customer actually sees
Transport Network, some terms Multicast Unicast Latency Jitter Loss Routing Router Switch VLAN IP Address Quality of Service (QOS) IGMP Failover Time to geek out a little…
Transport Network, a little latency Home Head End Transport Network Access Network Latency
Access Network & Home Great! My head hurts and I’m feeling underwhelmed… what’s next??? What’s in a home? What does the customer expect? What factors can affect the “in home” experience? How is IPTV different than analogue cable in the home?
Access Network & Home, terms… Are you starting to hate technology terms yet? DSLAM ONT / NID Residential Gateway (RG) Set Top Box (STB) DHCP
Quality of Experience (QoE) The end user experience is the primary and most important goal, it’s how you will retain the customer
Expectations, Effects & Opportunities IPTV vs. Over the Top Video (OTT) Multiple Services in the Home, i.e. Revenue Retention Network Performance Metrics and Monitoring Tiling and Freezing and Green Bars, Oh My!
Q&A Thank you for your time, your understanding, your patience and your sanity… I promise I will return your sanity after questions! Shaun Carlson Senior Network Engineer, Arvig ph: (218) , em:
