Distributed SIP Conference Management with Autonomously Authenticated Sources and its Application to an H.264 Videoconferencing Software for Mobiles
Multimedia Tools and Applications, 53(2):349--370
2011

Marker: TI-I

Zusammenfassung: The design of conferencing systems for achieving efficient and flexible communication in a fully distributed, infrastructure-independent fashion is a promising direction, both in terms of research and practical development. In the particular case of video communication, the seamless adaptation to heterogeneous mobile devices poses an additional strong challenge to those seeking for interoperable and easy-to-deploy solutions. In this paper, we make several contributions towards a generic peer-to-peer (P2P) videoconferencing solution that extends into the mobile realm. We describe the essential building blocks for conference management and media distribution that are necessary for a distributed conferencing approach. Establishing a distributed SIP conference focus, participants share the conference according to their individually given capabilities and resources in terms of bandwidth and processing power rather than in a centralized and fixed way. Overall concepts and SIP-primitives for such an autonomous organization are presented. Security issues that derive from this decentralized identity management are resolved by so-called \em Overlay AuthoCast, a novel use of cryptographically generated identifiers. Furthermore, this work is dedicated to the development of a software-based H.264 video codec implementation and the specific aspects resulting from tuning such a highly resource-intensive software codec to the given target platform of a standard consumer smartphone.

A Temporally Scalable Video Codec and its Applications to a Video Conferencing System with Dynamic Network Adaption for Mobiles
IEEE Transactions on Consumer Electronics, 57(3):1408--1415
2011

Marker: TI-I

Zusammenfassung: In this paper we present a multipoint video conferencing system that adapts to heterogeneous members including mobiles. The system is built upon a low complexity scalable extension of our H.264 codec DAVC, and a congestion-aware dynamic adaptation layer. We show that our temporally scaled video codec DSVC has the same RD performance as the non-scaled version with comparable configuration. We achieve this by QP cascading, i.e., assigning gradually refining quantization parameters to the declining temporal layers. The different quantization of frames does not lead to visually distinguishable quality fluctuations. We also present and analyze a mobile-compliant version of DSVC at reduced complexity that still admits comparable performance. Finally, we report on early work of dynamic layer tuning. Derived of delay variation measures, senders exploit scalable video layering to adapt the video transmission to varying network conditions. Initial results indicate that video performance remains close to optimal.

A Middleware for Transparent Group Communication of Globally Distributed Actors
Middleware Posters 2011
Verlag: ACM, DL, New York, USA

Marker: TI-I

Zusammenfassung: Actors have been designed for loosely coupled concurrent systems based on asynchronous message passing. This model is of particular relevance for Internet-wide distribution, but cannot unfold its full potential due to the lack of a globally available messaging service for groups. We present a message-oriented publish/subscribe middleware that enables global group communication at near-IP performance. Based on this transparent group layer, we build libcppa, an Actor library with modular support for group semantics that is compliant to the new C++ standard.
