* How is the current market of TV and internet TV? <br>
* Are people ready to accept internet TV? <br>
* What are most potential audience’s ages? locations? their expectations? <br>
* what is the rime we expect to make Internet TV form a large enough popularity? <br>


'''Why do we need Internet TV?'''
To answer these question, we did some research on the internet. We found the market analysis of two country: Greek and China. Although it is only 2 country, China have one third of the TV users in the world and is here by very representative of the global TV users. Below are the info of the Greek TV market. <br>
'''Country Fundamentals of Greek'''


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.
[[Image:Contry fundatmentals greek.JPG]]


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


Don’t now how the current tv works but internet tv works as follow:
[[Image:Equipment.JPG]]
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.

'''Who are the key players of internet TV?'''http://en.wikipedia.org/wiki/IPTV --> vendors
'''TV market of China '''
China has the world’s largest number of cable television subscribers – 115 million by the
end of 2004 – and is expected to have 150 million by 2010. According to the latest
statistics from State Administration of Radio, Film and Television (SARFT) China’s
2,569 broadcasting operators broadcast 2,355 radio programs and 1,255 TV programs by
the end of 2004. China’s cable TV network stretches over 4 million kilometers. The value
of China’s cable TV equipment market reached $1.6 billion in 2000. Growing at a 45
percent clip, the market is expected to be $12 billion by 2005. The broadcasting and TV
equipment sector will continue to be promising over the coming years because the market
is still relatively under-developed in China. SARFT has announced that it intends to
provide TV services to 90 percent of the population, a feat that will require much more
satellite, microwave and optical fiber equipment as well as program production and TV
reception equipment.


http://en.wikipedia.org/wiki/Internet_tv
China has the world’s largest number of cable television subscribers – 115 million by the
end of 2004 – and is expected to have 150 million by 2010.
Chinese households now own more than 400 million TV sets and they enjoy a standard 50-channel cable selection for an average fee of $2 per month. China TV subscribers occupy one third of the international TV users.
It is analyzed that China TV viewers’ demand for TV programming is 9 million hours each year, while the current supply is only 2 to 3 million hours. China’s TV stations such as CCTV and provincial level TV stations plan to launch 50-80 pay TV channels by the end of 2005.


A recently survey reflected seven main behaviors of consumers [2]:<br>
• First, consumers look for high-quality programs and regard this as a decisive factor in whether or not to choose digital TV. <br>
• Second, consumers’ complaints focus on too many commercials inserted into
programs. This indirectly pushes them to explore new paths to acquire information and entertainment and thus issues a challenge to the current TV model of earning profits. <br>
• Third, most consumers know little about digital TV, which results in insufficient dynamic to foster digital TV markets.<br>
• Fourth, consumers prefer to choose programs by themselves and to avoid
commercials rather than enjoying high definition digital TV, which conveys that
consumers regard the content as their first preference.<br>
• Fifth, consumers are willing to pay extra charges for news and TV plays in the first place.<br>
• Sixth, it is whether consumers recognize the content and how they evaluate its value that obstructs the popularization of digital TV. Therefore, the satisfaction of experimental users is of vital importance. <br>
• Seventh, many consumers hesitate to accept digital TV for they are waiting to see its perspective in the days ahead. <br>

My Object of the future is: Bio-diesel


Bio-diesel, a clean burning alternative fuel

Cereals.JPG

What is Bio-diesel?
Bio-diesel is a domestic, renewable fuel for diesel engines derived from natural oils like soybean oil, and which meets the specifications of ASTM D 6751 [1]

Made from:
Vegetable oils, peanuts, corn, soybean etc….

Why Bio-diesel?
- Safer, cleaner alternative to petroleum diesel
- Alternative for the continuing increasing oil prices
- Experts predicted that gas will be exhausted in 50 years
- No engine modifications required, no need to change vehicles, spare parts …
- Bio-diesel cuts down on targeted emissions, air pollution

Prices
The price of biodiesel in the United States has come down from an average $3.50 per US gallon ($0.92/l) in 1997 to $1.85 per US gallon ($0.49/l) in 2002. [2] A gallon gasoline cost about $2.28/gallon and a gallon diesel is about $2.48 /gallon.

Bio-diesel, a renewable fuel for a cleaner tomorrow!
Up till now, there are already 1700 Bio-diesel tank-stations in Germany. The European Union is even setting a goal by 2010 that 5.75% of the total volume of energy usage to come from Bio-diesel. With more research to bring down the cost and product awareness, Bio-diesel is the product for the future!!
