TAILIEUCHUNG - Lecture BSc Multimedia - Chapter 13: MPEG-4 video

Chapter 13: MPEG-4 video. In this chapter, students will be able to understand: MPEG-4, content-based Interactivity, MPEG-4 example, MPEG-4 sprite example, MPEG-4 video compression, VOP-based vs. frame-based coding,. | CM3106 Chapter 13 MPEG-4 Video Prof David Marshall and Dr Kirill Sidorov CARDIFF UNIVERSITY PRIFYSCOL CAERpv School of Computer Science Informatics Cardiff University UK MPEG-4 Main aim interactivity. Previous MPEG-1 2 were frame based. Virtually no interactivity. MPEG-4 is not only aimed to improve compression but to improve functionality and interactivity. MPEG-4 targets Digital TV. Interactive graphics computer games. Interactive multimedia WWW. MPEG-4 addresses the needs of authors service providers end users. CM3106 Chapter 13 MPEG-4 Video MPEG-4 1 Content-based Interactivity Content-based manipulation and bitstream editing Interactive home shopping. Home movie production and editing. Insertion of sign language interpreter or subtitles. Digital effects . fade-ins . Hybrid natural and synthetic data Animation and synthetic sound can be composed with natural audio and video in a game. A viewer can translate or remove a graphic overlay to view the video beneath it. Graphics and sound can be rendered from different points of observation. CM3106 Chapter 13 MPEG-4 Video Interactivity
