| Fabulous Video Coder Package ProWebcams, like most things, range from simple to complex. If you understand the essence of a simple Webcam setup, increasing the complexity is only a matter of adding functionality through software, custom code and/or equipment connections. A simple Webcam setup consists of a digital camera attached to your computer, typically through the USB port. The camera part of the Webcam setup is just a digital camera -- there’s really nothing special going on there. The ’Webcam’ nature of the camera comes with the software. Webcam software ’grabs a frame’ from the digital camera at a preset interval (for example, the software might grab a still image from the camera once every 30 seconds) and transfers it to another location for viewing. If you’re interested in using your Webcam for streaming video, you’ll want a Webcam system with a high frame rate. Frame rate indicates the number of pictures the software can grab and transfer in one second. For streaming video, you need a minimum rate of at least 15 frames per second (fps), and 30 fps is ideal. To achieve high frame rates, you need a high-speed Internet connection. Once it captures a frame, the software broadcasts the image over your Internet connection. There are several broadcast methods. Using the most common method, the software turns that image into a JPEG file and uploads it to a Web server using File Transfer Protocol (FTP). You can easily place a JPEG image on any Web page. | |
