Vivo Software has produced an enticing line of products designed for real-time
audio and video on-demand. Both VivoActive Player and PowerPlayer deliver
real-time audio and video content to the web as plug-ins for Netscape (v2.x and
later) or as ActiveX controls for Internet Explorer (v3.x and later). The
freeware VivoActive Player will give you an idea of the possibilities that exist
with Vivo's technology, but to realize its true potential you'll need to
purchase the commercial PowerPlayer client ($12.95). In addition to letting you
save Vivo content, the PowerPlayer uses the proprietary H.263 video codec for
enhanced video and Vivo's SIREN technology for high-fidelity audio. The
freeware player is also limited by the lack of playback controls and program
settings, whereas the PowerPlayer delivers an intuitive interface with playback
controls, download status, content information, and an option for viewing video
content double-size (or twice its original size).
But where Vivo really shines is in its line of development tools. The set of
three VivoActive Production Tools begins with the $49 VideoNow client. VideoNow
is specifically designed for entry-level developers wanting to add basic video
and/or audio to their personal home pages or small business web sites. The
client's primary selling point is that it produces multimedia content optimized
for streaming over the bandwidth of most modems. Of its limitations, a maximum
video size of 160 x 120 pixels, the lack of variable streaming rates, and the
inability to embed captions, HTML, Visual Basic scripts, and other events into
its streaming content stand out as the most glaring. And at only $49, it should
come as no surprise that VideoNow also lacks quite a few more of the advanced
features found in Vivo's high-end production tools.
Like the other two production tools from Vivo, VideoNow lets you take either an
AVI or a QuickTime file and convert it to streamed video content (with
compression ratios of up to 200:1) that can be served from any type of web
server. Or you can go the audio-only route by converting WAV or AIFF files into
streamed audio content. In either case, the best aspect of all three production
tools is that they are server independent, meaning that VivoActive content can
be hosted on and streamed from standard HTTP (web) servers as well as
specialized media servers like Microsoft NetShow, Netscape Live Media, and
RealNetworks Real Media.
Formerly the stallion in Vivo's production stable, VivoActive Producer has
been relegated to mid-range duties by the enterprise-level VivoActive Producer
for NetShow. Yet despite being overshadowed by the NetShow release, VivoActive
Producer ($199) is likely to be the best solution for many developers. Of the
three Vivo production tools, it's also the only one that is currently available
for evaluation over the 'net. Producer offers many advantages over VideoNow;
four of the most important are video optimization capabilities (matches the
streaming content with the network connection of your choice - modem, ISDN, T1,
LAN, etc.), support for ActiveX and Live Connect (allows you to use Visual Basic
Script or Javascript to create multimedia presentations with synchronized video,
audio, graphics, slides, and URLs), a maximum video size of 352 x 288 pixels,
and optional "FM quality" sound (16kbps) for your audio content.
Vivo's current showcase development tool is VivoActive Producer for NetShow,
which goes far beyond the capabilities of its two siblings but also carries a
far more expensive price tag ($695). The main benefit of Producer for NetShow
is that it gives developers the ability to broadcast live multimedia content
using Microsoft's Advanced Streaming Format (ASF). Producer for NetShow
includes the Microsoft NetShow server for broadcasting live events, or you can
use any standard web server for hosting on-demand streaming content. Of the
three tools, Producer for NetShow is the only one that will allow you to create
interactive ASF-based web pages with content markers, text captions,
choreographed web page sequencing, and automatic HTML page generation. If you
need the best and can afford the best, VivoActive Producer for NetShow is
definitely the route to go.
Overall, Vivo presents an audio/video streaming solution that nearly equals
RealNetworks' RealPlayer, and it does so with the benefit to developers of not
having to purchase a specialized server for delivering real-time multimedia
content. While the VivoActive Player and VivoActive Production Tools lack
support for RealFlash content (a critical feature of RealPlayer 5.0), the video
content produced by Vivo is nearly on the same level as that of RealPlayer and
the audio isn't too far behind. RealPlayer takes the nod at this point for the
reasons listed above and also because it sports a more advanced set of features,
but Vivo definitely merits considerable attention. Developers especially will
want to take a close look at Vivo for the fact that is one of the few streaming
technologies available that allows you to serve real-time multimedia content
from a standard web server.
Pros: Excellent real-time audio and video streaming capabilities without
the need for specialized servers
Cons: Lacks some of the more advanced features of RealPlayer, quality
lags slightly behind RealPlayer
