Live webcasting technology is driven
by various market forces, with an emphasis on the opportunities
of broadcasting television. In business, this is typically “business
television” to inform a large workforce of company policy
or information. Another popular model is the “presidential
address” or “marketing launch” style of corporate
However, outside of the major news channels and the large corporates,
especially the big IT providers, extensive webcasting is rare.
Increasing access to broadband and simpler technical platforms
are now creating
a greater interest in technical solutions to webcasting.
IPTV is one driver of webcasting technologies, though typically this is
done through a single infrastructure with end-users using
set-top boxes rather than through desktop PC’s. Besides using the
internet for delivery of these services, Cable and Satellite operators
are moving from analogue to digital systems, where the video compression
technologies allow them to deliver more channels over existing
infrastructures. Though not necessarily IP based networks, many
of the streaming technologies share similar solutions to webcasting.
Mobile phones network providers are taking an increasing interest
in webcasting technologies. Currently, growth in this sector
is primarily in Video on Demand (VOD) through 3GPP standards. This
architecture does allow for live streaming, but the consumer market
does not appear to be quite ready for this.
CCTV Security has seen a large increase in the use of IP networks
to readily allow transmission of video from remote locations
over existing IP networking. Again, compression technologies
allow large quantities of video to be recorded and digital store means
access to archived footage can be very quick.
For all these niches the added advantage of capturing live
events and presentations to make them available for video
on demand use increases the value of live encoding and transmission.
