Hands-On DVB-T and DVB-H: Protocols and Engineering
Course Description
This Hands-On course provides a technical engineering study of television broadcast systems and infrastructures by examineing the delivery of TV images for SDTV broadcast quality where MPEG-2 has been used for many years. It will also examine what is required for HDTV using MPEG-4 or H.264 and for delivering compressed television to handheld devices.
Broadcasting systems depend upon delivery over MPEG transport streams so the course will examine how MPEG-2 transport streams can be used to carry services encoded in MPEG-2, MPEG-4 and H.264. Hands-on demonstrations and analysis of services will be used to explore the actual operation of real services. This will provide an understanding of how service information is delivered and how conditional access is encoded. The course will also examine the architecture of set top boxes for DVB-T and address the issues of middleware and chip-sets.
DVB-H can be used to deploy services for either broadcastmulticast or video on demand. These services run over IP and deploy IPTV techniques. Demonstrations of how video can be delivered over IP will be run in the classroom and protocol analysers used to explore the technical mechanisms and protocols used.
Students Will Learn
Describe In Detail DVB-T And DVB-H Digital TV Services
Identify How TV Can Be Encoded Using MPEG-2, MPEG-4 And H.264

Target Audience
This course is intended for developers, technically qualified users, system integrators, application builders and those who need a technical overview who are new to Digital TV systems used in the TV industry.
Prerequisites
No prior background in electronics, transmission or programming will be assumed and the course will concentrate upon functional aspects and technology comparisons rather than in the construction of the electronics themselves. A background such as that obtained from the one day DVB-T and DVB-H overview will be assumed.
