This Hands-On course examines the delivery of TV images for SDTV and HDTV to broadcast quality where MPEG-2 has been used for many years. However to deliver higher resolutions without more bandwidth greater compression is needed so the course will examine advanced Video encoding, MPEG-4 and H.264.
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. It 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 and address the issues of middleware and interfaces for digital display technology and audio output for modern home theater interfaces.
The course will examine and focus on NTSCATSC North American standards video and TV but will compare these with European PALDVB and BTSC standards.

Target Audience
This course is intended for Telecommunications professionals, developers, chip designers, application builders and those who need a solid technical overview of the latest techniques in digital TV broadcasting and HDTV 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.

Equipment Requirements (This apply's to our hands-on courses only)
BTS always provides equipment to have a very successful Hands-On course. BTS also encourages all attendees to bring their own equipment to the course. This will provide attendees the opportunity to incorporate their own gear into the labs and gain valuable training using their specific equipment.
