still demands special skills to ensure
that transmission services operate

The consensus is, that provided SIs
stay on top of their game, they should
not just survive but thrive in the IP
era. "This transition [to IP] leads to a

excel in both broadcast and IT," says

Swamp Or Swim
The IABM has noted that the
professional broadcast and media
industry is valued at US$49 billion,
a fraction of the value of the world's
IT and telecom industries. Taking
the positives from this, it suggested
that manufacturers shouldn't try to
reinvent the wheel but reassign their
R&D resources into working with the IT
industry. But is there any danger of the
bespoke SI industry being swamped by
the IT giants?
Phillips says IT companies certainly
