Beskrivning

This book describes the fundamentals and details of MPEG-2 Systems technologyWritten by an expert in the field, this book examines the MPEG-2 system specification as developed in the early 1990’s, as well as its evolution into the fourth edition of the MPEG-2 systems standard, published in 2013. While MPEG-2 systems will continue to evolve further, this book describes the MPEG-2 system functionality as of October 2013. Furthermore, relevant background information is provided. The discussion of MPEG-2 system functionality requires knowledge of various fundamental issues, such as timing, and supported content formats. Therefore also some basic information on video and audio coding is provided, including their evolution. Also other content formats supported in MPEG-2 systems are described, as far as needed to understand MPEG-2 systems. Ordered logically working from the basics and background through to the details and fundamentals of MPEG-2 transport streams and program streamsExplores important issues within the standardization process itselfPuts the developments on MPEG-2 systems into historic perspectiveIncludes support of 3D Video and transport of AVC, SVC and MVCConcludes with additional issues such as real-time interface, delivery over IP networks and usage by application standardization bodiesPredicts a continuing promising future for MPEG-2 transport streams

Mer om författaren

Jan van der Meer, Independent Consultant, The NetherlandsJan van der Meer retired from Philips as Director of Standardization in July 2008; he is currently an independent consultant. Jan worked for Philips from 1979 until 2008 and is now an independent consultant. He has played a leading role in the MPEG standards committee almost from its very beginning, contributing not only to the developments of the MPEG-1, MPEG-2 and MPEG-4 standards, but also to their usage in specific application areas, such as specified by 3GPP, DAVIC, DVB, IETF and ISMA. Jan is worldwide acknowledged for his contributions to MPEG and other standard bodies and is (co-)inventor of 12 patents. He has chaired the MPEG Systems Group and discussed and promoted the use of MPEG technologies in a large variety of standardization bodies.
