Philips/CE/DN/PdB - 10/9/2015 - 5 Philips Digital Networks CONFIDENTIAL 5 Philips Softworks MPEG-4 Features (2) l MPEG-4 Audio u a range of codecs for speech and music u high level of scalability u seamless adaptation to varying bandwidth l MPEG-4 Graphics u VRML based u binary format for transport u streaming of animations at a few kbit/sec

6. Philips/CE/DN/PdB - 10/9/2015 - 6 Philips Digital Networks CONFIDENTIAL 6 Philips Softworks MPEG-4 Features (3) l MPEG-4 Scenes u MPEG-4 is about Objects ! u Scenes define how to compose objects u Dynamic composition n composition may vary in time and space u Suitable for Personalized Services n user specific composition u Efficient transport format

7. Philips/CE/DN/PdB - 10/9/2015 - 7 Philips Digital Networks CONFIDENTIAL 7 Philips Softworks Object-Based Coding Object Oriented s Free composition of graphics, and video objects into scenes (overlays) s Audio and video objects can be independently manipulated s Arbitrary shapes (binary or alpha blended) s BIFS : text, 2D, and 3D binary format s separate front and background s multiple foreground objects s variable spatial placing of objects s alpha shape to blend visual objects l Object-Based Coding MPEG-4 is a great vehicle for: s Interaction at the end user level s Capturing user profile s Adding value to the content Object #1: Main Program (Newscast) Object #3: Graphic Overlay (Sponsor) Object #4: Graphic Overlay (Stock Ticker)  Philips 40%  SONY 25%  Panasonic 12%  Thomson 34%  Gemstar 30% Object #2: Graphic Overlay (Station ID)  Philips 40%  SONY 25%  Panasonic 12%  Thomson 34%  Gemstar 30% Composed Image
