Rik Van de Walle is the first to document MPEG-21, a current & hot topic', which is stimulating interest in the multimedia community and quickly becoming a standardized technology. Multimedia technology provides the different players in the value and delivery chain with an excess of information and services. However, no complete solutions exist that allow different communities (content, financial, communication, computer and consumer electronics and their customers), each with their own models, rules, procedures, interests and content formats, to interact efficiently using this complex infrastructure. Developing a common (big picture) MPEG-21 multimedia framework would facilitate co-operation between sectors and support a more efficient implementation and integration of the different models, resulting in an enhanced user experience. Thus, MPEG-21, the multimedia framework, seeks to fill the gaps and create the big picture of multimedia standards. It aims to guarantee interoperability by focusing on how the elements of a multimedia application infrastructure should relate, integrate and interact. Finally, where open standards for elements are missing, MPEG-21 is providing new technologies to fill the gaps. Serving as a timely and important reference for a burgeoning market, this indispensable text is edited by multimedia experts and_is an_invaluable_reference for_all those in the industry. MPEG-21 guarantees interoperability between multimedia systems by focusing on the elements of a multimedia application infrastructure. Presents a comprehensive overview of the technical issues, which MPEG-21 has standardised including, DID (Digital Item Declaration), DII (Digital Item Identification) and file format and those already in a mature state (e.g. MPEG-21 Digital Item Adaption). First book to deal with MPEG-21, which is a hot multimedia topic. Gained significant interest from the multimedia community. Includes chapters by leading experts in the field who have contr

Create, edit, modify and convert multimedia files using FFmpeg, the most versatile open source audio and video processing tool available for Linux, Mac and Windows users. After reading this book, you will be able to work with video and audio files, images, text, animations, fonts, subtitles and metadata like a pro. It begins with a simple introduction to FFmpeg executables — ffmpeg, ffprobe and ffplay, and explains how you can use them to process multimedia containers, streams, audio channels, maps and metadata. It then describes how you can easily edit, enhance and convert audio, video, image and text files. There are dedicated chapters for filters, audio, subtitles and metadata, as well as FFmpeg tips and tricks. Sample lists of FFmpeg filters, encoders, decoders, formats and codecs are also available as appendices. Quick Start Guide to FFmpeg is for anyone who needs to edit or process multimedia files including studio professionals, broadcast personnel, content creators, podcasters, librarians, archivists and webmasters. It will be indispensable for those wanting to process a variety of multimedia files from the command line and inside shell scripts or custom-built software. You will: Convert from one format to another e.g. video-to-video, video-to-audio, video-to-image, image-to-video, video-to-animation, animation-to-video, text-to-audio, text-to-video Edit video files by cutting them with and without re-encoding, appending, resizing, changing frame rate and aspect ratio, mixing in audio Use filters to rotate, flip, crop, overlay (side-by-side or inset), remove logos, blur, smooth and sharpen, apply transitions as well as speed up or down playback Edit audio files by changing, normalizing or compressing volume, mixing and splitting channels and detecting silence. Also, learn to generate waveforms as video or images Add subtitles, place them anywhere on the screen, use custom fonts and colors, and use different languages Learn how to import, export and remove metadata, add MP3 tags (including album art), set global and stream-specific metadata, export and remove metadata Automate your FFmpeg tasks.

More and more information, audio and video but also a range of other information type, is generated, processed and used by machines today, even though the end user may be a human. The result over the past 15 years has been a substantial increase in the type of information and change in the way humans generate, classify, store, search, access and consume information. Conversion of information to digital form is a prerequisite for this enhanced machine role, but must be done having in mind requirements such as compactness, fidelity, interpretability etc.  This book provides an overview of the basic technology and mechanisms underpinning the operation of MPEG standards. It is a valuable reference for those making decisions in products and services based on digital media, those with general background, engaged in studies or developments of MPEG-related implementations, and those curious about MPEG and its role in the development of successful, standard technologies. Offers an overview of what’s behind MP3, digital television, online movies and why these innovations changed the world; Provides a comprehensive treatment of all aspects of signal digitization; Presents not only the state-of-the-art, but also what are the drivers of what is coming next and what is developing in key R&D labs; Provides examples of new human sense experiences for all sorts of users and new business opportunities these offer.

The MPEG committee standardized the MPEG AVC (H.264) video coding standard in May 2003. The standard has since seen strong interest and adoption from the industry. A competing standard developed by Microsoft, referred to as VC-1, was standardized in SMPTE in April 2006. VC-1 is essentially a standardized version of Microsoft's Windows Media Video (WMV-9). Both H.264 and VC-1 are highly efficient compression standards that enable high-quality video services such as IPTV and Blu-ray Disc. H.264 and VC-1 are both mandated for high definition video services on Blu-ray Disc. These two standards are expected to form the basis for a new generation of high-quality broadband video services. The VC-1 and H.264 Video Compression Standards for Broadband Video Services covers these video coding standards, as well as issues in broadband video delivery. No other book about H.264 or VC-1 covers the standards in such detail. This book interprets the complex standards specifications and makes these new technologies accessible. Both authors have more than 12 years experience working on video compression and communications. The VC-1 and H.264 Video Compression Standards for Broadband Video Services is designed for researchers and a professional audience, including video engineers, and practitioners in consumer electronics, telecommunications and media compression industries. This book is also suitable as a secondary text or reference for advanced-level students in computer science and electrical engineering. .
