Understanding DVB-H
Course Duration:
2 days
Training Course Description:
This 2-day course provides a technical understanding of how modern
television services can be delivered to mobile devices. These
devices might be specially equipped telephones, PDAs or Lap-top PCs.
To appreciate the different potential services an understanding of
Digital Video Broadcasting techniques and encoding is required.
Making services mobile brings its own problems that need to be
solved with innovative engineering solutions. Different kinds of
video and TV service can be offered through mobile devices and the
service must be designed to deliver service when and where required.
This course is designed for delegates who need an introduction to
all of the aspects of the technology, equipment and network
architectures that are being utilised to provide these services. The
course also provides a comparison with some other broadcast
technologies to expose the competitive pressures that drive the
technology specifications.
When you have completed this course you will be able to:
- Describe the delivery of Digital
Video Broadcasting to Hand-held devices (DVB-H)
- Appreciate how very low bit rate
Video is encoded
- Select appropriate encoding and
delivery standards
- Appreciate mechanisms for error
reduction and control
- Appreciate the trend in the
technologies
Prerequisites:
Prior knowledge of IPTV systems will be assumed such as that
obtained from the 2-day Introduction to IPTV Broadcasting Systems
course.
