Abstract :
An MPEG-4 audio-visual scene is composed of various types of media data represented as individual objects. It includes a scene description that refers to the spatio-temporal specification and behaviors of the individual objects. The MPEG-4 compatible player should be equipped with the decoding tools such as a scene description decoder or parser, media decoder, presenter, and so on. The requirement of the decoding tools of an MPEG-4 audio-visual scene is indicated by the profiles. This paper describes a content complexity adaptation technique, which makes the receiving content´s profile adaptable to the consumer´s equipments. For this goal, we propose the scalable scene tree that is simpler format for complying with the MPEG-4 scene structure. Moreover, we design the profile adaptation rules and show experimental results through several simulations.
