ArticlesInternet Video: Small Isn't Beautiful


June 1996 / Reviews / Internet Video: Small Isn't Beautiful

The promise is real-time video over the Internet; the reality is less exciting.

By Stephen Satchell and H. B. J. Clifford

Don't sell your cable-TV stock just yet. Internet video broadcasts for your PC are in their infancy, waiting for better communications links.

VDOnet's VDOLive software promises over-the-Internet real-time playback of audio and video material on PCs and Macs. The company claims slow video and AM-quality sound over a 14.4-Kbps connection, up to 10 to 15 frames of video per second over a 28.8-Kbps link, and even better video and sound over faster hookups. Don't confuse this with videoconferencing products like CU-SeeMe (Cornell University/White Pine Software), which are designed for meetings where multiple partici pants contribute sound and video.

We downloaded version 1.0 of the VDOLive viewer for Windows 95 from the Web. When we went to view a clip on a computer lacking a sound card, VDOLive complained but showed us silent video. Although VDOLive's screen is tiny--only 160 by 120 pixels--you can double the size of the viewer window to ease the eyestrain. With Netscape 2.0, the VDOLive plug-in puts integrated video on a Web page.

When we ran VDOLive using an SVGA board at 256 colors, the picture was sometimes muddy and dark, and other times acceptably bright. The darkness was especially annoying with a network news feed shown on a bright-white surrounding, although with the stand-alone player you can manipulate the desktop background for easier viewing. Sometimes the image quality was quite high with considerable detail, while at other times it was heavily pixelated and uninformative. Overall, VDOLive worked best with talking heads and bright scenes.

With a 2 8.8-Kbps link on a 486DX2/66, the audio would occasionally break up and we experienced far fewer video frames than VDOnet claims--3 frames every 5 seconds was typical. This problem appeared to be mostly caused by our particular Internet link rather than by a flaw in either the server or the viewer.

Our experience indicates the Internet isn't ready for real-time audio and video without a faster-than-modem-speed connection. During a few near-perfect modem sessions, VDOLive delivered a few frames per second. However, a high-speed link is clearly crucial. ISDN users should see far better frame rates and audio quality.

My approach to software engineering is far more pragmatic than it is theoretical--and no language better exemplifies this than C++.
