Synchronization models for multimedia presentation with user participation
TLDR
This paper addresses the key issue of providingflexible multimedia presentation with user participation and suggests synchronization models that can specify the user participation during the presentation and suggests adynamic timed Petri nets structure that can model pre-emptions and modifications to the temporal characteristics of the net.Abstract:
This paper addresses the key issue of providingflexible multimedia presentation with user participation and suggests synchronization models that can specify the user participation during the presentation. We study models like the Petrinet-based hypertext model and the object composition Petri nets (OCPN). We suggest adynamic timed Petri nets structure that can model pre-emptions and modifications to the temporal characteristics of the net. This structure can be adopted by the OCPN to facilitate modeling of multimedia synchronization characteristics with dynamic user participation. We show that the suggested enhancements for the dynamic timed Petri nets satisfy all the properties of the Petri net theory. We use the suggested enhancements to model typical scenarios in a multimedia presentation with user inputs.read more

Generating and matching hashes of multimedia content
TL;DR: In this paper, a concatenation of binary hash words, one for each frame, is used to identify a possibly compressed audio signal, a block of hash words derived therefrom is matched by a computer with a large database.

Method of enhancing rendering of a content item, client system and server system
TL;DR: In this paper, a client system (200, 220) receives a content item and the user can mark the received content item as being of interest. In response to said marking, tracking means automatically provide identifying data for the marked content item to a remote server system (250).

Petri-net-based hypertext: document structure with browsing semantics
P. David Stotts,Richard Furuta +1 more
TL;DR: A formal definition of the Trellis model of hypertext is presented and an authoring and browsing prototype called αTrellis that is based on the model is described, which is a generalization of existing directed graph-based forms ofhypertext.
