Summary:

Digital content is everywhere and has revolutionized the way broadcasters and Web sites deliver images, sound, video, and multimedia to their audiences. Today, as Web site managers and broadcasters are identifying and targeting distinct segments in these audiences, broadcast and Web engineers are faced with the challenge of creating digital content that can be tailored and personalized to reach these distinct and differing audience segments. This book provides the in-depth technical details of transcoding and annotation that broadcast and Web engineers need to know to create accessible and reusable digital content capable of being tailored and personalized for a particular audience. It also provides complete coverage of metadata tagging, natural language processing, voice and video analysis, and multimedia summarization and translation, which are the underpinning technologies of digital content transcoding and annotation.
