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]

What kind of new innovation had been made in the era of internet TV?I’m not sure of all the new innovations. But I found a couple innovations that can used on Internet TV. On called Mixtv see paper [1]

Driving Forces

Description:

Over the next 5 years, the mobile convergence will develop in three theme

Convergence of technology will develop with communication,broadcast and computing

Technological capabilities that can be developed on the move are rapidly burring the distinction between mobile phone and PCs.

Ongoing advances in sophistication,functionality and personalization will continue to sustain handset renewal

Enablers:

o Ubiquity : With forecast billion mobile devices in use by 2007, the 'anytime anywhere' advatages of mobile services are very apparent

o Immediacy : Information can be accessed, delivered and acted upon in real time by the user without the start-up time required for a desktop PC

o Personalization : Mobiles are now personal accessories, capable of holding data and enabling access to information and services which can be tailored to the needs of the individual

o Localization : Recognising where the user is located and matching information or services to that location adds a unique value to mobile services

o Convergence : Thechnological capabilities that can be deployed on the move are rapidly blurring the distinction between mobile phones and PCs. Ongoing advances in sophistication, functionality and personalisation will continue to sustain handset renewal

Inhibitors:

o Design and potable size(Display,resolution,memory.os) o Usability(Input/output device) ㅇCapability(speed),multi task)and interface with another product

Paradigms:

People to communication and entertain something to spend a lot of time to use mobile phone anywhere and anytime grows rapidly

Experts:

Support from LGE, SSE, NOKIA

Timing:

Since last 4 years,camera phone launched Convergence phone Mega trend
