steve h. - Re: Intel's Video Phone

The video phone product from Intel includes either an Analog Video Camera and a plug-in video capture card. Or, if your computer has a USB (Universal Serial Bus) port, a Digital Video Camera and a cable to plug directly into the USB port. A software package is also included which handles compression of the image as well as audio compression.
This software package is an upgrade to a piece of software that major OEMs (HP, Compaq, Dell, etc.) ship with their Pentium systems.

Because of the slow speed of data transmission using a modem, the video and audio images need to be compressed to reduce their size so they can be more quickly transmitted at the limited speed of modems.

At the receiving end, these compressed images must be decompressed.

Thus, a faster CPU will perform these functions (Compression and Decompression) quicker than a slow one, giving a more realistic impression of actual video.

I've been playing with Microsoft NetMeeting (free download from the MS Web site, also comes with IE4) and a Connectix Quickcam (the oldest, original B&W model that I borrowed). It's fussy to used & get set up, but I am surprised at how well it works and the price is right. This is on a P-166 non-MMX. My impression also is that the phone line is the limiting factor, but with a faster phone line, larger picture or faster frame rate, the CPU would quickly become the limiting factor. I'm using a USRX 56k X2 modem, but in this application I am getting no more than 33.6, even if the other person also has a 56k modem.
