This paper presents the concept of the Media State Vector (MSV), an implementation of uni-dimensional motion in real time. The MSV is intended as a general representation of media navigation and a basis for synchronization of multi-device media presentations. The MSV is motivated by the idea that media navigation can be decoupled from media content and(More)
Peer-to-peer (P2P) technology potentially offers a promising basis for efficient, scalable and low-cost delivery of live content to large numbers of simultaneous users. However, the decentralized nature of P2P and the existence of untrusted peers makes commercial exploitation difficult. In this paper we describe Closed Swarms (CS), a P2P based content(More)
We observe a mismatch between how academia models publish-subscribe systems for marketplace applications and how such applications are actually structured by the industry. To address this mismatch, we propose a new structure for online marketplace applications. A stateful and open publish-subscribe system exposes internal state and events to clients,(More)
Media players and frameworks all depend on the ability to produce correctly timed audiovisual effects. More formally, sequencing is the process of translating timed data into correctly timed presentation. Though sequencing logic is a central part of all multimedia applications, it tends to be tightly integrated with specific media formats, authoring models,(More)
