Broadcast
Essentials for Telecoms and IT Professionals
Course Duration:
2 days
Training Course Description:
The course provide delegates with an understanding of the
technologies, vocabulary and techniques and used in contemporary
television broadcast systems and operations. Packet based delivery
of broadcast services such as IPTV and Video on Demand (VoD) are
becoming increasingly popular. However for many professionals coming
from a Telecoms or IT background, little is understood of
traditional broadcast technologies or the requirements for quality
of service within those technologies. It is of prime importance that
these considerations are understood so that IPTV and VoD services
can offer the same quality of experience to the consumer as those
that exist today in traditional broadcast services. Also IT and
Telecoms professionals working on IPTV or VoD implementations will
need to be able to communicate effectively with broadcast
counterparts working on thier project. The format of this course is
classroom based with demonstrations.
