What Exactly IS Streaming Video?
Streaming video is a sequence of "moving images"
that are sent in compressed form over the Internet
and displayed by the viewer as they arrive. Streaming
media is streaming video with sound. With streaming
video or streaming media, a Web user does not have
to wait to download a large file before seeing the
video or hearing the sound. Instead, the media is
sent in a continuous stream and is played as it arrives.
The user needs a player, which is a special program
that uncompresses and sends video data to the display
and audio data to speakers. A player can be either
an integral part of a browser or downloaded from the
software maker's Web site.
Major streaming video and streaming media technologies
include RealSystem G2 from RealNetwork, Microsoft
Windows Media Technologies (including its NetShow
Services and Theater Server), and VDO. Microsoft's
approach uses the standard MPEG compression algorithm
for video. The other approaches use proprietary algorithms.
(The program that does the compression and decompression
is sometimes called the codec.) Microsoft's technology
offers streaming audio at up to 96 Kbps and streaming
video at up to 8 Mbps (for the NetShow Theater Server).
However, for most Web users, the streaming video will
be limited to the data rates of the connection (for
example, up to 128 Kbps with an ISDN connection).
Microsoft's streaming media files are in its Advanced
Streaming Format (ASF).
Streaming video is usually sent from prerecorded
video files, but can be distributed as part of a live
broadcast "feed." In a live broadcast, the
video signal is converted into a compressed digital
signal and transmitted from a special Web server that
is able to do multicast, sending the same file to
multiple users at the same time.
Who's watching streaming video?
5% of Web users watch streaming video daily Posted
by ZDNet Research
74% of Web users have viewed
online video at least once; 51% do so a minimum of
once a month; 27% watch streaming video at least once
a week; and 5% view Web video streams daily, according
to Online Publishers Association.
FUELED BY THE RISE IN high-speed Web access, the
majority of Internet users view at least one streaming
video feed per month, according to a study released
Tuesday by the Online Publishers Association. The
organization reported that nearly three out of four
Web users--74 percent--have viewed online video at
least once; 51 percent do so a minimum of once a month;
27 percent watch streaming video at least once a week;
and 5 percent view Web video streams daily. For the
report, "Drivers & Barriers To Online Video
Viewing," the Online Publishers Association and
Frank N. Magid Associates surveyed more than 27,000
Web users age 13 and older last October and November.
The researchers intercepted respondents from 25 news,
information, and entertainment Web sites, including
USAToday.com, GameSpot.com, and Weather.com.
In fact, not only do many Web users regularly watch
streaming video, but they would apparently watch even
more, if additional clips were available. "One
of the major takeaways is that there's more demand
for video than consumers can find," said Michael
Zimbalist, president of the Online Publishers Association.
That conclusion is based on the finding that 59 percent
of respondents discovered online videos via random
Web surfing, while only 43 percent of respondents
said they had previously watched a streaming video
on the site where they were intercepted--mainly because
they didn't know videos were available on the site.
If more video was available--and respondents knew
where to find it--they would presumably watch more.
Most survey respondents--70 percent--reported having
watched an online video ad, and many indicated that
the spots spurred them to action. When asked what
they did, if anything, as a result of viewing the
ad, 34 percent said they investigated a Web site,
while 15 percent requested additional information,
14 percent visited a brick-and-mortar store, 10 percent
forwarded the ad to another person, 9 percent made
a purchase, and 3 percent ordered a subscription.
But more than half of the respondents--56 percent--said
they hadn't done any of those activities in response
to the ad.
Can streaming media unlock new sales?
Immature technology has limited the widespread adoption
of streaming applications to larger enterprises, but
analysts and some early adopters forecast a boom during
the next few years.
by Garry Kranz
For Steve Waterhouse, the decision to add streaming
media applications to his company's Web operations
has paid off handsomely.
"During the past six months, we've seen a 300
percent increase in Web traffic as a result. Streaming
media definitely has been a revenue generator for
us, because the applications enable us to add 50 percent
more content to our training programs through follow-up
services. We're also adding streaming media training
courses on a subscription basis, and project that
could increase our revenue 20 percent to 30 percent,"
said Waterhouse, founder of sales-training company
The Waterhouse Group in Scarborough, Maine.
Early adopters of streaming media are found in the
financial services, training and health care industries,
according to Christine Perey, president of Perey Research
and Consulting in Placerville, Calif. "In these
industries, the actual content of the file is the
asset being sold. Companies in which knowledge transfer
is a core competency are better able to make money
from streaming media technologies," said Perey.
Streaming media is common among large, widely dispersed
enterprises, according to Lou Latham, an analyst with
Stamford, Conn.-based Gartner. But a growth boom is
on the horizon.
"By 2004, we expect that one-third to one-half
of all companies will be using streaming media applications
for training, virtual announcements and for business-to-business
portals for help desks, customer service and marketing,"
Latham said.
Assess potential advantages
Although few companies are making money from streaming
media, many are realizing cost savings and other benefits,
said Philip Graham, vice president of the Internet
Streaming Media Alliance, a nonprofit industry consortium.
"If your CEO needs to be in two places at once,
he could do so by streaming a live broadcast to both
sites. Aside from savings on travel costs, this actually
helps the company seem smaller to employees, not larger,"
said Graham.
Enterprises can boost employee productivity by streaming
training programs, including video on demand, to all
who need it simultaneously. "Instead of spending
days in a classroom, streaming video and audio training
enable new employees to get training on site and be
productive the very first day on the job," Graham
said.
Streaming media commonly is used for interactive
customer service demonstration videos. "These
can help cut down on expensive customer service calls
to your call center, which adds to your bottom line,"
he said.
Selling your content on a recurring basis is a promising
feature of maturing streaming technology, said Dale
Sorenson, president of streaming media consulting
firm Sorenson USA in New York City. "Most videos
are promotional in nature, and companies want to give
them away as often as possible. But streaming video
will make a new range of applications available in
which the video becomes the product that you sell,"
said Sorenson.
Quantify costs
Adding streaming media to your Web operations requires
technical expertise but generally can be done at minimal
cost, users and industry observers say.
"The scary thing is how low cost it is,"
said Waterhouse, who estimates his company invested
around $1,000 for software licenses, hardware and
production equipment to establish streaming media
as a recurring service offering.
Equipment purchases and contracting with creative
talent are the main costs, according to Latham. "Aside
from content creation, you'll have to invest in infrastructure
upgrades and buy dedicated servers. You don't want
to use your Web server to stream, since this is a
very data-intensive activity," said Latham.
Sorenson said enterprises should implement cautiously,
gauging the marketplace to see how technology is evolving.
Proprietary authentication systems that are imposed
on existing enterprise architecture often are "deeply
flawed" and some don't prevent data from being
decrypted once a file is opened, he said.
Nonetheless, enterprises ought to ponder streaming
media strategies in anticipation of massive deployment
during the next few years. According to Perey, businesses
spent $600 million to $700 million through 1999 for
products that enable streaming media applications.
By 2003, she predicts that figure will grow to around
$4 billion. "A great many companies are running
pilot projects to try and improve streaming media
technology," Perey said, "because they sense
a heartfelt and proven need for it within business
units."
