Virtual Real Worlds

Writen by Ken Rigby

In future work, play, and study will be transformed by the use of 3D models and environments. These environments and models will be created to be as realistic as possible by use of textures and perspectives that will provide the user with a sense of "being there".

It has been forecast that these Virtual Worlds will revolutionize the way we shop "made to measure" will return as clothes will be produced to fit the individual. Virtual 3D museums will contain realistic recreations of the real thing; the great Pyramids, Taj Mahhal, great Wall of China, etc. will be experienced from your front room. A leisurely walk through Englands green and pleasant lands can be experienced with all the sights and sounds as of you were there.

Virtual conferencing will allow the participants to select an environment akin to the subject being discussed.

The latest generation have been exposed to this 3D environment or have experience of it most of their lives; to them it is quite natural and accept the virtual real world concept enthusiastically. They readily accept the possibility of people meeting in an environment of there choosing while being physically somewhere else in the real world; in fact they can't understand why it doesn't exist today.

This is discussed at greater length at web site www.mellanium.com

Ken has spent most of his life working in the aerospace industry. His interest in the Virtual Real World has been born out of a real need to access information easier and less painfully by using 3D models and environments. See http://mellanium.com/ for more information.

Reselling Web Conferencing Services How To Profit From The Coming Boom In Web Amp Video Conferencing

Writen by Dan Richmond

If you want to make money in an online business, then you need to find a product or service that is fresh, up-to-date and that hasn't been beaten to death with hundreds of copy-cat affiliates. Web and video conferencing are relatively new applications, and becoming a reseller of online conferencing services could be a good way to start up or add to an already existing online business. Let's take a look at the prospects for this type of online enterprise.

First of all, web and video conferencing is an up-and-coming field of activity. Business is becoming increasingly globalized and many companies now have staff or clients located in distant locations, sometimes in other countries or on other continents. Online meetings are being used by some of the leading enterprises, but there are many more organizations that have not even begun to take advantage of web or video conferencing.

This is a huge market waiting to be tapped, and with the increasing penetration of broadband use both in the workplace and at home, the market grows larger with each passing month.

Just as there are relatively few companies using web and video conferencing, there are comparatively few resellers or affiliate sellers of these services to compete with. If you would like to get into this business then you should do an online search for web conferencing resellers or affiliates, and choose a program that you can effectively handle.

Typically, affiliate programs for these kinds of services are easy to enter. In many cases all you have to do is sign up and get an affiliate code or url and paste it onto your website and you are in business. However, if you want to be an effective affiliate for web and video conferencing, or for that matter, any other product or service, the best way to sell it is by using it yourself and really knowing what it is all about. Only then can you truly recommend the product in a convincing way.

A step above an affiliate is to become a reseller. Usually this requires a comprehensive training in the web and video conferencing system and there may also be an entry fee attached to becoming a reseller. Whereas affiliates simply refer potential clients to the conferencing service, Resellers are responsible for signing up the clients themselves. The advantage though, is that a reseller is likely to get a higher percentage of the signup and monthly subscription fees paid to the conferencing service by his or her referred clients.

If you are successful as a reseller then you will earn a residual income for as long as the people signed-up by you subscribe to the conferencing service.

Whether you decide to become an affiliate or a reseller, the key to cashing in on the coming boom in online conferencing is to study the market, know the product thoroughly and then place it before your web visitors or mailing list audience in a compelling and convincing manner. Another key factor to success is to make a timely move, a product or service that is "new" today will be commonplace tomorrow.

Isdn Vs Adslwhich Is Better For Video Conferencing

Writen by Michael Lemm

When deciding on the best bandwidth configuration to run your video conferencing on...you may think you have endless choices. Sometimes it appears that way when you may actually be limited to just a few. Here's a comparison when your only choices are between ISDN and ADSL.

So the question than becomes this.

Which is better in the sense of connection speed and for Video conferencing between ISDN PRI (1.544Mbps) to ADSL (1.544Mbps)?

PRI ISDN T1 is the industrial strength flavor of ISDN, and is intended for users with much greater capacity requirements. PRI has 23 B channels plus one 64 Kbps D channel. Each channel has a 64Kbps capacity, enabling a total transmission speed of up to 1.536Mbps. With PRI ISDN, you can pre-define the number of channels used for specific types of calls or data delivery. What this means is that you can use the various channels for accomplishing different things on different channels simultaneously. In other words, PRI ISDN offers much greater flexibility than that provided by BRI ISDN. Additionally, the D channel is used as the switching channel that communicates with the Central Office for Call Management. It is used to carry local and long distance traffic.

An ADSL circuit connects an ADSL modem on each end of a twisted-pair telephone line, creating three information channels -- a high speed downstream channel, a medium speed duplex channel, depending on the implementation of the ADSL architecture, and a POTS (Plain Old Telephone Service) or an ISDN channel. The POTS/ISDN channel is split off from the digital modem by filters, thus guaranteeing uninterrupted POTS/ISDN, even if ADSL fails. The high speed channel ranges from 1.5 to 6.1 Mbps, while duplex rates range from 16 to 832 kbps. Each channel can be submultiplexed to form multiple, lower rate channels, depending on the system.

ADSL modems provide data rates consistent with North American and European digital hierarchies and can be purchased with various speed ranges and capabilities. The minimum configuration provides 1.5 or 2.0 Mbps downstream and a 16 kbps duplex channel; others provide rates of 6.1 Mbps and 64 kbps duplex. Products with downstream rates up to 8 Mbps and duplex rates up to 640 kbps are available today. ADSL modems will accommodate ATM transport with variable rates and compensation for ATM overhead, as well as IP protocols.

Downstream data rates depend on a number of factors, including the length of the copper line, its wire gauge, presence of bridged taps, and cross-coupled interference. Line attenuation increases with line length and frequency, and decreases as wire diameter increases.

They are completely different technologies used for different things. With ADSL you are generally given Internet access and with a PRI you get 1472 kbps of usable bandwidth to be used in a combination of various ways. The key difference is that with a PRI, you never actually have to connect to the Internet as you do with DSL. Therefore, a video call doesn't have to use IP as it most likely would with DSL. Therefore things that affect call quality like latency are generally not as a big a factor with ISDN.

Many companies still use ISDN PRIs for video conferencing to power multiple video calls simultaneously. A lot of people are now using both ISDN and Internet access via DSL/T1/T3/Cable/etc. for their video needs. Generally ADSL is far cheaper but the quality isn't necessarily as good because the customer has little control over the path an IP call takes through the Internet, but that my friend is another conversation for another time.

Ip Cameras A New Booming Market

Writen by Wes Fernley

What is a IP Network Camera?

In simplest terms, an IP Camera is a stand-alone device that transmits audio and video through a standard CAT5 Network Cable. It has a built-in web server which allows the camera to run individually without a PC having to be connected. It also allows you to view the audio and video by connecting directly to the camera with your internet browser without any software being installed. This allows you access the camera from any location, even over the Internet.

IP cameras have many advantages over tradition CCTV security cameras. Some of these features include wireless connectivity, the ability to view video remotely over the Internet, the ability to record to a remote location and lower cost.

Advanced features of Network Cameras can offer added security for certain applications. These features include, Motion Detection, Pan/Tilt/Zoom, Infrared, Analog Output and Two-way Audio.

Lets discuss these features in greater detail.

Motion Detection

Some Network Cameras come with a feature called Motion Detection. Hot-Spots can be setup within the video frame to detect motion. Once motion is detected, the camera will begin recording or generate a snapshot which can be Emailed or sent to a web server via FTP of the detected motion. Snapshots can also be sent of images prior to the motion and after the motion.

Pan/Tilt/Zoom

Having the ability to Pan and Tilt adds greater security if you have a large viewing area. Once logged into a Network Camera with Pan and Tilt capabilities, controls appear next to your video allowing you to move the camera left, right, up and down. The controls can be used even over the Internet.

Along with the Pan and Tilt feature, some cameras come with Zoom. Zooming is also handy when a greater detail of video is needed. Network Cameras can come with two methods of Zooming: Optical and Digital. One is called Digital Zoom.

Digital Zoom discards pixels around the edge of the video fitting the remaining pixels into the same space to give the appearance of Zooming in. This comes with the expense of resolution and causes the Zoomed image to look very pixilated.

A post was made on the NetworkCameraReviews.com forums that addresses the differences between digital zoom and optical zoom. Click here to view the post.

Infrared

When needing to view video in the dark, Infrared is the way to go. Cameras can come with a built-in IR (Infrared) lens or the ability for an add-on IR lens to be equipped. Infrared is a wave of light that is outside of the visible part of the color spectrum. Infrared illuminators shine this wave of light which the lens picks up.

Analog Output

Some cameras come with an Analog Output to configure your camera to be notified of opened doors, alarms, or other events. Once notified of these events, the camera will start taking snapshots or video.

Two-way Audio

A Majority of cameras have audio built-in to the camera. This allows you to hear audio along with the video the camera displays. Some cameras come with Two-Way Audio.

There are two types of Two-Way Audio. One is a Full-Duplex Two-Way Audio that allows the user at the PC to hear audio from the camera and also speak back to the camera and have audio come out of the camera itself. Some cameras have a speaker port on the back to plug in external speakers which will give off the audio. The second type is a Two-Way Audio within the camera itself. The camera will pickup audio and send the audio to the speakers hookedup to the camera.

In the next article we will be addressing how IP cameras work.
