So it wasn’t too surprising, when the cable operators and the phone service began offering the so-called triple play, of cable TV, high-speed internet and digital voice services.Not to be outdone, the telephone carriers countered by adding TV to create a triple play of their own.The consumer embrace of online video with, soon send the cable companies and the telcos hurting each other on a collision course.

To enjoy TV everywhere, you will still need to subscribe to purchase speeding cable service and be authenticated on each of your devices.
OTT and Telephone companies
While cable companies work to move their content on the web devices, telephone companies are going in the other direction, putting web content onto TV.
Why? Because the traditional phone business is in decline, as consumers switch their phone service cable offerings, or worse, cancel their landline accounts and use their mobile phones as a primary phones.The telephone companies obviously need to replace that lost landline phone revenue and prevent customer from canceling other services, or cutting the telephone cord completely.
Without online video service swelling, telcos have placed their bet on internet protocol TV, IPTV for short. As a means to shore up their product and grow their customer base, or at the very least, returning their current customers.At its most basic, IPTV workspace streaming television content over private network to set top box(STB), that is connected to your TV.One of the biggest challenges for IPTV services is to match the picture quality with cable TV.
It’s far easier to deliver acceptable video resolution of a small screen smartphone, than to reproduce HD like resolution on a big screen TV.
To match cable like quality IPTV, providers are relying on content delivery networks, or CDNs.That store content across the network geographically distributed servers, rather than one central location.So for instance, when a request is made from Manchester England to view a video that originates in Los Angeles, you can take a long time to cover that distance.Better instead to catch the video somewhere close like london, and serve it from there.
By distributing content, in this way close to the end customer, CDNs help reduce bottlenecks.The resultant start-up delays stall out, or video that strains of the lower quality resolution, the types of performance attributes the collectively contribute to quality of service(or QoS).
Consumers win because their content is delivered more quickly and with better quality.IPTV providers win, because they increase customer satisfaction.
Last mile solution
As we know, because telephone companies owned the last mile, that final leg of delivering the video content to a customer.They are close to the consumer, and can offer better quality and more bandwidth savings and third party CDNs.To assure the highest quality viewing experience, the IPTV providers must monitor their content delivery networks to isolate quickly fix problems, and make sure that they have enough capacity to handle peak demand.
