Berlin [u.a.]Interactive media streams with real-time characteristics, such as those produced by shared whiteboards, distributed Java applets or shared VRML view-ers, are rapidly gaining importance. Current solutions to the recording of interac-tive media streams are limited to one specific application (e.g. one specific shared whiteboard). In this paper we present a generic recording service that enables the recording and playback of this new class of media. To facilitate the generic recording we have defined a profile for the Real-Time Transport Proto-col (RTP) that covers common aspects of the interactive media class in analogy to the profile for audio and video. Based on this profile we introduce a general-ized recording service that enables the recording and playback of arbitrary inter-active media.

IEEE Computer Soc., 1999 A General Framework and Communication Protocol for the Transmission of Interactive Media with Real-Time Characteristics . Los Alamitos, Calif. [u.a.]In this paper we present a general framework for the transmission of interactive media with real-time characteristics, i.e. media involving user interaction. By identifying and supporting the common aspects of interactive media the framework allows the development of generic services for distributed, collaborative work involving the transmission of interactive media.
- Silvia Pfeiffer, Rainer Lienhart und Wolfgang Effelsberg. IEEE Computer Soc. Press, 1999 Scene Determination Based on Video and Audio Features . Los Alamitos, Calif. [u.a.]Determining automatically what constitutes a scene in a video is a challenging task, particularly since there is no precise definition of the term scene. It is left to the individual to set attributes shared by consecutive shot which group them into scenes. Certain basic attributes such as dialogs, like settings and continuing sounds are consis-tent indicators. We have therefore developed a scheme for identifying scenes which clusters shots according to detected dialogs, like settings and similar audio. Results from experiments show automatic identification of these types of scenes to be reliable.

Eine neue objektorientierte Analysetechnik für die Entwicklung von Audio-Inhaltsanalyse-Algorithmen
Mannheim, . 99-006
Die Entwicklung von Audioanalysealgorithmen ist eine klassische, funktionsorientierte Aufgabe. Trotzdem ist es sinnvoll, solche Algorithmen mit einer objektorientierten Programmiersprache wie C++ zu implementieren, insbesondere um die Wiederverwendung von Routinen durch andere Projektteilnehmer zu erleichtern. Eine klassische objektorientierte Analyse z.B. nach UMT nähert sich dem Problem jedoch aus der falschen Sicht: nämlich aus Datensicht, obwohl die Aufgabe in einer Modellierung von Funktionen besteht. Wir stellen hier eine geeignetere Modellierungstechnik vor, mit der wir sehr gute Resultate erzielt haben.
