Brief definition about DVD

DVD, also known as Digital Video Disc or Digital Versatile Disc, is an optical disc storage media format, and was invented and developed by Philips, Sony, TOSHIBA, and Time Warner in 1995. Its main uses are video and data storage. blank DVD s are of the same dimensions as compact discs (blank CD s), but store more than six times as much data.

Variations of the term DVD often indicate the way data is stored on the discs: DVD-ROM (read only memory) has data that can only be read and not written; DVD-R and DVD+R (recordable) can record data only once, and then function as a DVD-ROM; DVD-RW (re-writable), DVD+RW, and DVD-RAM (random access memory) can all record and erase data multiple times. The wavelength used by standard DVD lasers is 650 nm; thus, the light has a red color.

DVD-Video and DVD-Audio discs refer to properly formatted and structured video and audio content, respectively. Other types of DVDs, including those with video content, may be referred to as DVD Data discs.

The official DVD specification documents have never defined the initialism DVD. Usage in the present day varies, with Digital Versatile Disc, Digital Video Disc, and DVD being the most common. DVD was originally used as an initialism for the unofficial term digital videodisk. It was reported in 1995, at the time of the specification finalization, that the letters officially stood for Digital Versatile Disc (due to nonvideo applications).

A newsgroup FAQ written by Jim Taylor (a prominent figure in the industry) claims that four years later, in 1999, the DVD Forum stated that the format name was simply the three letters “DVD” and did not stand for anything.

The DVD Forum website has a section called “DVD Primer” in which the answer to the question, “What does DVD mean?” reads, “The keyword is ‘versatile.’ Digital Versatile Discs provide superb video, audio and data storage and access—all on one disc.”

Various Broadband Connection

Broadband, also known as broadband internet access, is a high data-transmission rate Internet connection that make use of two of the most popular consumer broadband technologies – cable modem and DSL. With any of these technologies, your Internet connection could easily transmit data faster than 56 kilobits per second (the highest speed of a traditional dial-up modem).

The popularity of broadband internet access radically increased in many countries starting 2000. These kinds of Internet access can surf hundred times faster than conventional dial-up modems, thus the name “high-speed Internet”.

Commercial broadband Internet commonly has 256 kilobit per second, which is about the slowest broadband speed for connections advertised worldwide. However, since there is no standard bitrate defined by the industry, the term “broadband” could imply also low-bitrate transmissions or others call “narrowband”. Consequently, some consumers turn out to be disappointed about the promised Internet speed of their connections.

The Technology Behind Broadband Internet Access

The most important assessment you have to make is the kind of broadband internet you want. There are various technologies behind broadband access and you should understand these technologies to fully appreciate this service. Things you have to think about include cost, speed requirements and your location, whether home or office. Since there are many choices for high-speed connections, you should be able to know how each one works and find out which service can benefit your work or lifestyle the most.

Some Internet service providers use multi-linking technologies that achieve a faster surfing speed by doubling the speed of dial-up modems. However, if you wish to subscribe to this feature, you should have two dial-up accounts, two telephone lines, two modems and the ISP provider for multilinking. This is the oldest kind of technology and was used way before DSL, cable broadband and other higher-speed connections were available.

The most common technologies for broadband in many countries are DSL and cable modems.

The most common broadband internet is Digital Subscriber Line (DSL). This technology works by using your phone lines to transmit digital signals directly, without having to convert to analog signals. DSL offer higher data rates and allows you to connect anytime without using your phone line, making it available for incoming calls. There are many kinds of DSL, but asymmetric digital subscriber line (ADSL) is probably the most popular for subscribers.

Cable is another type of broadband internet, which uses the fiber networks to give your cable television at home and use them for internet access. Meaning, you get to divide a given amount of bandwidth for a neighborhood. The limitation of cable internet is that some condominiums and buildings do not have cable installed. When this is the case, it could take time to install your internet subscription because building codes and other legal issues should first be done.

Satellite is the kind of broadband internet that is frequently recommended as an alternative for DSL. However, satellite internet is more expensive because you will need an antenna or a dish to receive data signals from the provider’s satellite.

Other new technologies, such as optical fiber and VDSL are now adding to consumer’s choice for higher-speed Internet connections. Although fiber-optic internet services are used lately, the technology had played a vital role in allowing consumers to connect to broadband Internet using a more cost-effective solution even over larger coverage.

The biggest challenge in broadband is to offer the service to customers in any area, even with low-population densities. Since setting up the broadband Internet access in a particular area could cause many thousands of dollars for equipment alone, many service providers do not have the network in some rural areas for fear that they will not recover the costs.

Although some local Internet providers provide these solutions, many have limitations and drawbacks. The most common problem for rural Internet providers is that these companies usually depend on the quality of local telephone companies.

In some locations that have no DSL or cable Internet, Wi-Fi networks serve their Internet needs. In other countries, high-speed mobile Internet access, such as HSDPA, EV-DO and stationary-broadband WiMax are used.

With today’s modern world where businesses and even home-based employees rely on the Internet for everyday communications and worldwide access, broadband and other high-speed technologies present consumers and businesses a expedient way to hook up to the net.

Regardless of what you choose, you can really see the difference of dial-up from broadband internet in terms of speed, reliability and performance once you plugged your computer on.

Mobile Internet Satellite Broadband – chapter 3

Back in 1999 when we beta tested the first wireless mobile office with satellite broadband Internet we had something that no one lese had. Today you can buy these systems for $5,500 fully installed on any RV. We probably had $10,000 in the first system and we had mobile satellite number 34. Today there are thousands of systems out there. Continuing the beta testing story of the first broadband satellite internet system.

It appears the Canadian based companies for obvious reasons are gaining fast while the US companies were hampered by the FCC in the last few years, forcing communications to move out of the country, yet the customer bases will be here and many of these companies will have 50K subscribers in no time, and the US mighty powerhouses will end up with all the technology and hardware through acquisitions or set up new systems in the coming years with higher capabilities. But do not count out the GM Hughes Team, Craig McCaw (he is a lifer when it comes to passion of the industry) and of course Lockheed and Microsoft. Teledesic, and the other recent alliances and projects prove that the world will be more than united and on the same page it will be doing so in real time. Expect the human rights violations of yesterday to disappear in all nations, religion to be put in check and knowledge to be the universal truth. I would like to thank; John Kettlewell, Jon Haugan, Steven Genuser, Stacy, Allen, Steve Ford WB8IMY, Michael Tavern, Frank Morring, Kim Komando and a few other writers, researchers and industry insiders for all the data in our research. We have scoured over 20 magazines for the last year for bits and pieces of the puzzle and personally visited all kinds of people around the US for this input.

We at WashGuys are sitting on the latest and greatest technologies on this Planet. We will always be on the leading edge of anything that makes us great. And when we say us, we mean all of the US, but of course this costs the big bucks and we like out electronic toys, but it is not for everyone. Okay back to the talk. TracNet is another purely Internet Based satellite service and has download speeds of 400kbps, but since it is not directly two way it’s upload speed is 14.4 Mbps on a cell phone or at 9600 through the satellite, bummer, but it works no matter where you are in the US. Truck drivers like this one a lot. It also works about 100 miles from the coastline in a boat and is good on yachts. Many high-end motor homes have this system too. TrackNet uses the 802.11b wireless standard WiFi; this is at 11Mbps, same as an Ethernet network. The cool thing about this system is you can be outside on the grass in a park doing you work as long as you have the server in your car with the Trac net antenna set up. Of course you need some space for all this but the size of this technology is getting smaller and the price is coming down too. Right now this system costs about $6K. It uses the ExpressVu Bell Satellite and it requires a 14-inch antenna. Let me know if you want to see what the dome looks like. This will cost an additional $3,000. Cost is $ .99 per minute and after 900 minutes it is only $ .79 per minute. MotoSat System, 12Kbs on down load and 1.28Kbs on uplink all satellite, no cell phones unlimited use for $79 per month. Hell you can even watch TV on the damn thing.

Got to love the diehards from GM Hughes Spin off. What’s the catch? A 39 inch antenna, not exactly transportable or brief-casable. DataStorm it is called. Our WashGuy Command Center antenna is 42 inches high and 39 inches across in an ellipse shape. We believe the next wave of technology is where it is at however and predict this to be in place where WiFi is sitting on top of every billboard in the US for uplink and the antennas are 5 inches high and self tracking the downlink from the satellite and with this technology and user codes each company can help America track terrorists and once a terrorist is coded like a whale that has been tagged, you always know where he is. When will this be? Not long. Give it three, maybe four years or so tops, five if the FCC does not see it’s obvious value.

Another system, which may enter the market, is GE Capitals Americom Communications Unit. Our founder met the president of Americom once, about 8 years ago, interesting guy. Societe Europeene Des Satellite (SES) added these satellites to its 28 owned and 13 satellites that it has an interest in. Why? To have a piece at the broadband seamless global conductivity market. This was talked about in April 2 issue of Aviation Week and Space technology. This means that SES will also control AsiaSat and Embratel’s Brazil StarOne. Other articles to tell the history of this whole thing are; Nov 13 2000 AW&SPT and AW&SPT of July 24,2000. SES maybe the most profitable in the entire sector due to the contract backlogs of 6.4 Billion as of June 2001. So now what will they do with others entering the markets? It appears GE was smart to sell and now needs to get back into the game somehow. I see the coming of a new age. Where information, innovation, security, safety, will change the world. And just imagine the power it will give to all the research going on in the World. Very cool. Car Wash Guys are in close contact with these technologies so we can put a small antenna on every until and address the entire company and every crew in it every morning of everything going on by way of satellite video conferencing. WOW, we are almost here.

And that is the story of our Beta Test Project and we are glad to be a part of Communications History and we have now tested the satellite system in every city in the United States over 10,000 people. Think about it.

Mobile Internet Satellite Broadband – chapter 1

Being on the road has its advantages; the freedom is the biggest one. One draw back was the Internet Service, but having done much study on the mobile Internet Satellite Systems and future technologies; I was able to become a beta tester of the MotoSat system in 1999. I have used the system ever sense.

My company, the Car Wash Guys had joined forces with a Strategic Alliance of GM Hughes Satellite Division to beta test the First Fully Self contained, fully Networked Mobile Corporate Office, taking advantage of the newest in WiFi technology. We were the first in the world to have this powerful capabilities which at the time nearly blew away the Pentagon’s Performance with their 77 million dollar investment and Iridium Bailout.

Mobile Corporate Offices are the Wave of the future, where Network Centric Warfare (Net-Centric) in the marketplace combined with strategic mobile command centers used to create a network of networks, which will eventually dominate all of their market sectors. Corporate Giants are slowly learning the game is changing. And we are the ones teaching them. We are the leaders in technology and they will have to learn the hard way. Car Wash Guys are leading everyone’s industry this time. As far as the car wash industry is concerned we left them in the dust a decade ago. Today we use 20 times less water, a third of the labor and spend less than a tenth of the capital to do it. We now have much bigger fish to fry as we go for the gold. To work with this technology you must move your business at the speed of thought.

We at our Bravo research team of WashGuys, had been studying the newest in satellite technologies. Most of our recent studies have been on satellite data transmissions and as many of you know we have become very knowledgeable over the years with satellite communications, I happened to live next door in Malibu from a physicist who worked at the Rockwell Research Center in Thousand Oaks CA. First we would like to talk about actually data transmission speeds and problems associated with relays and problems of security of data when data jumps from satellite to satellite or from satellite to ground. Also with the problems of relay where any and all data can be recorded. As everyone knows the Pentagon bailed out the Iridium project, which is good since we have learned so much from this. The 75 million dollar contract helped pay the bills of 7 million a month including the 40 million per year to Boeing who flies the satellites. Iridium was nice in that it covered the whole Earth, all oceans and remote areas, with spare satellites ready just in case. Iridium had 66 satellites in orbit in use at about 485,000 up. Very close and helps with data lag associated with satellites which is normally a half second or more. The data can be transmitted at 1Mbs, which is slow considering the Wash Guys data transmission capabilities of 10-12.265 Mps up load and the 1Mbs download, faster than that of the US Department of Defense. The other problem we see with their system is the relay in Tempe, AZ home of Motorola, which is unsafe due to the newest wave of possible terrorist devices such as the brief case electronic impulse devises which work from building tops and could easily destroy its relay station. This is why other systems, which are not voice systems and generally web based and data use satellites are much better such as the Globalstar System.

With Globalstar, which is in debt and filed bankruptcy, due to small amount of debt to Qualcomm who is also in trouble and Loral, it may cease to exist. EuroCom has a neat system, which is used in the shipping industry and there is an interesting article in Professional Mariner this month about them and a few others. It is similar to Imersat and supports PBX and PABX systems on ships. Of course the bent pipe approach by GlobalStar is worth considering its 48 operational satellites and the four spares. Only real problem is the range of 70 degrees north to 60 degrees south. And also the gaps if you let’s say in the middle of the ocean at sea level in the South Atlantic and or middle of the Pacific. Several satellites can transmit the coded signal but unlike the Iridium system the Satellites do not talk to themselves. But all in all Global Star data transmissions are still about 9.6 KBPS and actually slightly less than the Iridium system, which does not have the lapse in service.

The Iridium of course is the Arthur C. Clark theory in practice and is worthy of note; the big problem right now with data transmission is the problems with direct sight to satellite, which we have encountered. Hard for submarines, and below decks on vessels or in buildings. Good for catching bad guys who have to go out in the open to use the phone, they do not work in caves either. Iridium like all of Microsoft software has triple redundancy, and uses CDMA technologies to gateway the data from transmission point into the terrestrial system. Inmarsat Systems include the I-4 system, which can transmit data at 432 MBPS turns out to be excellent for things like video conferencing. The newest satellites by Inmarsat are said to be able to 10 times more communications than the current ones. Since the Inmarsat satellites are at 22,300 miles up three satellites cover the Earth with 3 back-ups. But remember with that altitude there is a time delay. You will notice this when you see video feed from the Middle East Wars on live broadcasts on TV, CNN.
