“…Different approaches that try to overcome this problem are published. Used techniques are, among others, dynamic extended finite-state machine (DEFSM) models [Huang and Wang 1998], the Z notation [Shih et al 1999], Timed Petri Nets and the logic of temporal intervals [Little and Ghafoor 1990], Dynamic Petri Nets (DPN) [Tan and Guan 2005], and collections of Petri nets [Shih 1998]. Synchronization models and languages are, for example, proposed by Meira and Moura [1994], Schnepf et al [1996], Bailey et al [1998], Aygün and Zhang [2002], Presti et al [2002], Buchanan and Zellweger [2005], and Hakkoymaz [2009].…”

Hypervideos and interactive multimedia presentations allow the creation of fully interactive and enriched video. It is possible to organize video scenes in a nonlinear way. Additional information can be added to the video ranging from short descriptions to images and more videos. Hypervideos are video-based but also provide navigation between video scenes and additional multimedia elements. Interactive multimedia presentations consist of different media with a temporal and spatial synchronization that can be navigated via hyperlinks. Their creation and description requires description formats, multimedia models, and standardsas well as players. Specialized authoring tools with advanced editing functions allow authors to manage all media files, link and arrange them to an overall presentation, and keep an overview during the whole process. They considerably simplify the creation process compared to writing and editing description documents in simple text editors. Data formats need features that describe interactivity and nonlinear navigation while maintaining temporal and spatial synchronization. Players should be easy to use with extended feature sets keeping elements synchronized. In this article, we analyzed more than 400 papers for relevant work in this field. From the findings we discovered a set of trends and unsolved problems, and propose directions for future research.

Abstract. In this paper, we propose a functional testing method of media synchronization protocols, which control the synchronization between audio and movie, described in concurrent synchronous timed I/O automata. In order to trace all test sequences (I/O event sequences) with synchronization on the model, we need to execute each I/O event at an adequate timing which satisfies the whole timing constraint for all the given test sequences. However, the outputs are given from the IUT and uncontrollable. Also each output/synchronization timing may affect executable timing for its succeeding I/O events in the test sequences. In this paper, we propose a technique to derive a set of time intervals which make all the given test sequences executable, and propose a method for functional testing using the technique.

Abstract. In this paper, we propose a testing method for QoS functions in distributed multi-media systems, where we test whether playback of media objects is correctly implemented or not in a client side program according to the quality designated in advance, and/or whether a time lag between parallel playbacks of multiple media objects is controlled within the specified time interval. In the proposed technique, we describe test scenarios in timed EFSMs where we specify behavior of an input flow transfered to a given IUT (implementation under test) and behavior of playback with certain QoS functions observed from the IUT (e.g., the range of fluctuation of frame rates) . From the scenarios, we generate test sequences to test whether a given IUT realizes the QoS functions specified in the scenarios. In the proposed test method, we use a statistical approach where test sequences take samplings of actual frame rates and/or time lags when an IUT is executed, and report test results from ratio of samplings with low quality below a threshold in a normal distribution of all samplings. We have implemented a test system for test sequence execution in Java, and applied it to a video playback system.
