Streams vs. Data Transfer

 

At WebTVPro, we provide commercial quality streaming media solutions for your site at affordable monthly rates based on the amount of data you transfer. This avoids the limitation of working with a fixed number of streams and the hassle of wondering when you need to get more. A stream is defined as one visitor's line to your data. So, if you had five streams allocated to your site then only five visitors could view or listen to your content at once.

Five people at once isn't very exciting when you're aware that there's millions of web surfers out there. And if you wanted even a thousand people to see your streaming content at once it could get very expensive on a per-stream basis; plus you'd be paying for streams that might not even get used. Knowing this, we decided that charging by the stream didn't make sense; it's expensive and many people are discouraged by the limit it places on the size of your potential audience. That's why we've made a substantial investment into this technology so that we can provide you with a nearly limitless number of streams and offer monthly rates based on the amount of data that you transfer.

Now, you don't have to worry about the number of streams you have available to your site and whether or not it's time to add more. That's our job and we are constantly monitoring our streaming video servers so that when there's a need for us to upgrade the number of streams available to our clients it's done without any hassle or added expense to you! We believe that this technology is the future of video, audio and animation delivery on the Internet and we are prepared to do whatever it takes to provide it to our clients at the highest level of quality possible.

Determining Bandwidth

Determining Bandwidth is a difficult number to calculate because there are so many terms to understand and also because there's no way of knowing how many people will be watching or listening to your data. To help you with this calculation we've included the following information:

Terms

bit = 1/8 of a byte (a "0" or a "1")
Kilobit (Kb) = 1,000 bits


byte = 8 bits (e.x. 00101101) or 1 character (e.x. "A")
Kilobyte (KB) = 1,000 bytes


Megabyte (mb) = 1,000,000 bytes
Gigabyte (gig) = 1,000,000,000 bytes


Kbs = Kilobits per second (1,000 bits in a second)
KB/sec = Kilobytes per seconds (1,000 bytes in a second)


Why the difference between Kbs and KB/sec? Because file sizes on a hard drive are measured in Kilobytes(KB) because they transfer data very quickly and data transfer over a modem is measured in Kilobits per second(Kbs) because it's comparatively slower than a hard drive.
