Limiting your bandwidth expense
Encoding your live event at lower bit rates will reduce your financial exposure. We can not limit the number of streams or the amount of bandwidth to your account. It is an open pipe!! Video uses about 4 times the bandwidth as Audio does. The more clients that watch your video the more bandwidth you consume…that is a good thing…someone is watching your video, the system is working for you.

Multi Bandwidth Technology
Multi Bandwidth technology is the process by which we create a few different versions of one audio/video clip. In most cases we create 3 versions of each clip. Each version is set up to best suit either a DSL Modems, Faster Cable Modems or even faster internal company computer networks. When a viewer sees the clip it will be the version best suited to them.

Bandwidth: The total amount of your video (data) a network connection is capable of sending through its system per second. This determines the length of time it will take to transmit your video data. A video that takes 1 minute to transmit across a DSL modem might only take 10 seconds over a company network, because it has a larger bandwidth capability, more data bits per second.

Buffering: Media video players assimilate the incoming video data and display the video to the viewer. During network congestion, this data may not be sufficient for the media player to continue smooth playback, the media player must pause to receive more data before resuming playback. The video or audio may stutter when this happens.

Caching / Cache: All computer data including video data which is frequently accessed is often stored in the computer's temporary memory so that it may be re-accessed at a quicker rate than if this data was stored on the computer's hard disk drive or reacquired over the internet. The process of storing this data is called caching. The type of memory that stores this data is called the cache.

Digital Rights ManagementDRM) Refers to selectively allowing the end-user to view or listen to a video clip. This term also used when referring to the software that enables Internet PPV 'Pay-Per-View' (see Pay-Per-View).

Digitizing and Encoding: Digitizing refers to the process of capturing original video off of traditional video tape and getting it on to or into a digital format for use on a computer. Some refer to Encoding as the process of converting ta digitized video file into one of the streaming video formats.
Latency: This is the delay of transmission of data. Refers to the time it takes for a router, upon receiving the data, to determine which router to forward the data to next. In live streaming video events their maybe a 10 to 20 second delay from the time a person speaks and the actual time it can be seen by the viewer…just like you see on CNN when interviews are on the other side of the world.

Network Congestion: Situation that occurs when the amount of data being transmitted exceeds the capacity of the network. This results in data transmission delays and possibly lost data. If a router becomes overloaded, it will slow down the data transfer, in video this is seen as a stutter of the video our audio signal.

Pay-Per-View: Just like pay-per-view events on television, this refers to streaming video events or clips where viewers pay to watch.

Streaming Video Media: This is basically television and radio for the computer, Streaming media technology converts other mediums (audio and video) to digital formats that can be played back instantly by computers.

Webcast: A live streaming media event broadcast for the Internet.

Windows Media and Silverlight Video: (wmv files) Streaming media software created by Microsoft.

Adobe Flash (flv and swf ) Streaming media software created by Adobe

QuickTime:(mov files) Digital media software created by Apple Computers, that can be streamed over the Internet.

RealPlayer: (rm files) Streaming media software created by RealNetworks for the Internet.

What is required to do a live streaming video event? You want to learn about doing some or all of the process for doing streaming videos AVCA can teach you, but here’s a brief idea to answer the question.
1) A Windows based computer with a reliable Internet connection.

2) Enough bandwidth on the upload speed of your Internet connection to cover the bit rate or bit rates you wish to send out.

4) A video capture device for your computer. There are many companies and models of video capture devices on the market. You will want to make sure that you purchase a device that is compatible with the windows media encoding software that you are using. The manufacturer of the device should be able to tell you if it will work with the windows media encoding software.

5) You need one of the several streaming video encoders like Windows Media Encoder from the Microsoft Windows

Firewalls
Firewalls can cause problems for live webcasting. You must setup your live connection on the outside of your firewall or have your network or ISP administrator do it for you.

Shopping Cart Setup Information: If you want to do PPV pay per view you wil need to add a shopping cart…with secure credit card features.

Testing,: There are many other issues like testing so clients can check their systems before a live event, reporting systems so you know how many watched your video…the list for doing this can be quite long. But if you are prepared to pay us we will be glad to help you in any area where you need help so you can do it on your own.
a new plug-in for use with third party applications that enables users to export Flash encoded audio and video directly from a third party authoring environment.
Flash Websites

There are several alternative approaches to using video with a Flash-based website. The overriding factor in choosing the optimum method for delivery is performance, which developers can best address by matching the appropriate delivery mechanism with the actual content. For example, approaches that work for

Embedded video is a straightforward method of delivering short video clips and has been around since Flash Player 6. Playback is limited to simple play and stop commands, and the video framerate must match that of the original video

Progressive download, is a technique where video files are cached on the user's local hard drive and played through the host video server at the time of viewing, a good advantage is there are no limitations to the file's size or duration of the video clip.

Streaming video files have many of the same properties of Progressive video files Data is not cached locally on a user's hard disk, this technique also provides the most secure method of delivering media.
