STAYING ON TOP OF
STREAMING TRENDS
Want to see if your current
streaming video offering
is behind the times?
Here are a few streaming
video files from 25 media sites, like
ABC, CBS, and ESPN. There are also 25
major corporate sites. I analyzed the
files and divided them into three categories—
conservative, mid-range and
aggressive—by screen resolution.
As you can see, the days of 320x240
video at 300 kbps (kilobits per second)
are long past. CNN streams most of
their videos at 640x360 at 800 kbps,
while prime time TV replays are often at
848x480 at 1.2 mbps (megabits per second).
Apple streamed their largest iPad
promotional video at 848x480 at a startling
2.7 mbps.
If you haven’t updated your streaming
video configuration in a year or two
(or three or four), you can deploy a larger
resolution, higher
quality stream that
your viewers can
stream and play in
real time. As with living
room television
sets, bigger is almost
always better when it
comes to streaming
video—otherwise, the
networks wouldn’t have
boosted the quality of their
streaming video.
Like it or not, you’re subtly
judged by the size and quality of your
streaming video, not only vis-a-vis the
ESPNs of the world, but particularly by
comparison with your competition, and
other videos your target
viewers frequently play. If
you’re still using that
320x240 at 300 kbps configuration,
you’re almost
certainly hurting the perception
of your organization
in the marketplace.
ADAPTIVE
STREAMING
The next point related to a
technology called adaptive streaming,
which is offered by a variety of vendors,
including Adobe (called Dynamic
Streaming), Microsoft (called Smooth
Streaming) and Apple for its iDevices
(called HTTP Live Streaming). Briefly,
adaptive streaming technologies encode
your source video files into multiple versions
at a variety of resolutions and data
rates. Then, the technology distributes the
optimal encoded file for your viewer’s connection
speed and playback device, and
continually monitors connection speed
during the broadcast to ensure that video
playback is sustained.
If streaming throughput drops during
the transmission for some reason, a lower
bitrate file is sent, sustaining the broadcast.
If throughput later increases, a higher
bitrate file will be sent. All this switching is
totally transparent to the viewer, who may
notice some differences in quality, but the stream will go on. As an example, Major League Baseball
encodes their games into 11 different versions for their subscription
video service, using multiple systems to adaptively
stream to their computer-based and mobile customers.
If you’re casually serving a few video files on your site,
adaptive streaming is definitely overkill. But if the quality
of your streaming video is critical to your training, marketing
or other activities, you should consider adaptive
streaming, particularly if you’re starting to think about
HD delivery, or distributing video to mobile phones.
WHO ARE YOUR VIEWERS?
In the June 2009 update to their Visual Networking Index
Forecast and Methodology report for 2008-2013, Cisco
reported that Internet video now accounted more than
one-third of all consumer Internet traffic, and that video
on demand traffic will grow at a 53 percent compound
annual growth rate between 2008 and 2103. Cisco further
predicted that mobile traffic will double every year through
2013, increasing by 66x between 2008 and 2013, and that
over 60 percent of that mobile traffic will be video by 2013.
B2C companies need to be more aggressive with offering
mobile video than B2B enterprises, since consumer
news and entertainment are the videos most accessed by
early adapters. For all organizations, however, if video is
mission critical to your marketing, sales, communication
or other enterprise pursuits, and you haven’t already
started thinking about a mobile strategy, now is the time.
