Internet TV

Why do we need Internet TV?

One reason of having internet TV is the flexibility of choosing your own program in your timetable. Your are not depend on the schedule of the normal TV. According to the article of Johna Till Johnson [2]. Another reason of IPTV is that there is a new opportunity for new players to create a creative packing and deliver it to the consumers. New players lead to better service towards to customer because of the competition.

What’s the difference between normal TV and Internet TV / How does internet TV work?

Don’t now how the current tv works but internet tv works as follow: Say that’s Consumer Jane there on the couch. She gets digital video from her local telephone company, which sends it to her over a DSL connection (DSL is rooted in IP, Thus, IPTIV is synonymous with sending TV over DSL). Remote in hand, Jane thumb-surfs via the channel-up arrow. The set-top (or media center) that came with the service issues what’s known as a join request. It wants to dip into a precached set of video frames. The request zings up the phone wire, to that buffer. Maybe it’s in an edge aggregator or maybe it’s in the D-slam, or digital subscribe line access multiplexer. Either way, the tuners aren’t inside anything at Jane’s house. The bits that make up the video frame in the buffer zing back into the box. The boxes used by cable and satellite operators use work differently. On-board tuners work by literally jumping frequencies each time somebody invokes a zap with the remote control. Then they need to demodulate the incoming signal, stabilize it and deal with any error-correction activities. If the processing chip isn’t beffy enough, that to do list can bog down. Symptom: slower zapper action

So conclusion you need a lot of bandwidth. [3]
