Multimedia synchronizations based on fidelity requirements

This paper focuses on definitions and models of multimedia distortion and fidelity, and their relations with multimedia synchronizations. The basic idea is that information of a multimedia object can be decomposed into content information (or non-time information) and time information. Time information can be either classified into centralized and decentralized time information, or classified into steady and dynamic time information. According to burstiness, diffusion and accumulation of distortion, several new forms of distortion are defined. A logic model of multimedia synchronizations based on synchronization controllers and transmissions is proposed. The main task of the controllers are distribution and mapping of distortion on the basis of fidelity. How to map distortion tolerance to QoS (quality of service) of logic channels for time or non-time information and physical channels, is addressed.
