Deadline for ending US analog broadcast

JRI Technology is offering a Video Compression course and DTV course, just before NAB, to help you understand compression and DTV technologies and digital video-based products, you will see at NAB (and others forthcoming), or to help you to design your own:

Advanced Video Compression [MPEG-4 Part 10/AVC/H.264]
3-day course; April 13-15, 2009
Please call for the option:
MPEG-1 & MPEG-2, 1&1/2-day course, April 13-14, 2009

The extension to AVC – scalable video coding (SVC) – is included in the course Syllabus. Also, the special project - DCI Requirements (Hollywood requirements for Digital Cinema) and SVC – is prepared for this course.

DCI Requirements and SVC

Compare the DCI Requirements (will be included in the course notes) and SVC features
Can SVC satisfy the DCI Requirements?
If “Yes”, propose the Digital Cinema SVC profile
Compare the proposed DC SVC profile with the JPEG 2000 Digital Cinema profile

SVC enables the transmission and decoding of partial bit streams to provide video services with lower temporal or spatial resolutions or reduced fidelity while retaining a reconstruction quality that is high relative to the rate of the partial bit streams. Hence, SVC provides functionalities such as graceful degradation in lossy transmission environments as well as bit rate, format, and power adaptation. These functionalities provide enhancements to transmission and storage applications. SVC has achieved significant improvements in coding efficiency with an increased degree of supported scalability relative to the scalable profiles of prior video coding standards.

Applications:
2k and 4k D-Cinema
Different importance (RoI)
Surveillance

Essential requirements for SVC:
– Similar coding efficiency compared to single-layer coding – for each subset of the scalable bit stream
– Little increase in decoding complexity compared to single-layer decoding that scales with the decoded spatio-temporal resolution and bit rate
– Support of temporal, spatial, and quality scalability
– Support of a backward compatible base layer (H.264/AVC in this case)
– Support of simple bit stream adaptations after encoding

Digital Television (DTV)
2-day course, April 16-17, 2009

Gain new insights on the inner workings of Digital Television (DTV). Enhance your knowledge of the principles of television transmission and the advantages and challenges of data delivery through terrestrial, satellite and cable networks. Gain an understanding of the DTV layered architecture, DTV transmission requirements, multiplexing, MPEG switching, audio components, and compatibility with traditional analog TV. Enhance your knowledge of topics that include: decoding issues, display problems, format conversion, baseband data stream handling, and conditional access.

The objective of the course is to bring the participants gracefully through all the DTV structure, features, and theory...then give them more practical information on subjects such as decoding issues, display problems, conversion, baseband data stream handling, etc. The course will also provide an in depth and structured introduction to the technology, its uses, opportunities/possibilities, and limitations. Digital TV is not simply the numerical equivalent to traditional analog television: the issues of becoming digital are covered, as well as the relevant compression technologies.
