Influence of Statistical Properties of Video Signals on the Power Dissipation of CMOS Circuits
(1994)
This paper describes a codesign environment based on the WWW (World Wide Web) and its implementation. Tool invocations and their respective results are linked using hypertext documents. We show how to configure a WWW browser for spawning design tools and how frequent tasks like documentation generation and retrieval are facilitated. The design flow can be adopted to the given application very easily. In addition we introduce the concept of a work flow called ‘design by documentation’. A WWW link to the results is given and experience using it in a codesign project is described.
Filling the Pipe
(1995)
An Information on Demand teleservice that was developed at the German National Research Center for Information Technology (GMD) provides remote access to multimedia information consisting of audio, video, and text [jonas et al. 94]. It uses a bidirectional narrowband message link between the end user and the service provider, and a unidirectional broadband data link from the service provider to the end user. Since the IoD teleservice is used across a satellite connection (among others), it turned out to be necessary to implement an access protocol that is optimized for the access of real-time multimedia data across a long-delay high-bandwidth link, a long fat pipe [jacobsen et al. 92]. This paper introduces the MediaService Protocol (MSP) and describes a prototype implementation (version 0.6).
Three emerging technologies are combined in a setup that has been installed and tested at GMD - the German National Research Center for Information Technology: 1. Multimedia Telecooperation Applications; 2. ATM-based high-speed networks; 3. Satellite links. The results are promising: After some initial problems, the complete scenario is up and running, allowing the interconnection of local high-speed infrastructures in rural areas to a core network via satellite. This paper describes the R&D background and state- of-the-art that led us to this approach. It then describes the communication infrastructure and the application infra- structure of the setup, the problems we had and the solu- tions we found. Finally, our experiences are summarized, and an outlook is made for future implementations.

ATM virtual studio services
(1996)
The term "virtual studio" refers to real-time 3D graphics systems used to render a virtual set in sync with live camera motion. As the camera pans and zooms, the virtual set is redrawn from the correct perspective. Using blue room techniques, actors in front of the real camera are then “placed in” the virtual set. Current virtual studio systems are centralized – the blue room, cameras, renderers etc. are located at a single site. However distributed configurations offer significant economies such as the sharing of expensive rendering equipment among many sites. This paper describes early expe- riences of the DVP1 project in the realization of a distributed virtual studio. In particular we de- scribe the first video production using a distributed virtual studio over ATM and make observations concerning network QOS requirements.
This paper presents an overview on and reports on early experiences of the European ACTS project AC089 called „Distributed Video Production (DVP)“ which started in late 1995. Central to DVP are distributed pilot applications for professional digital video production over ATM broadband networks (LAN and WAN). Distributed video production refers to situations where the cameras, recorders, switches, mixers and other equipment used in video production (or post-production) are located at several sites linked by high bandwidth network connections. The DVP project investigates requirements of broadcasters for several forms of distributed video production and runs a series of trials of distributed virtual studios, distributed rehearsals and remote video editing and retrieval. Together with North American partners a transatlantic broadband ATM link will be tested for distributed virtual reality simulations. This paper reports about two initial tests with a German public broadcaster and the German Telekom. DVP project partners are GMD and about 20 broadcasters, computer and video equipment manufacturers, and video production companies. More information can be obtained from http://viswiz.gmd.de/DVP
Distributed Video Production
(1996)
Video production is inherently distributed: Broadcasters are physically distributed over several sites and studios, they increasingly outsource video production and post-production to specialized studios or upcoming virtual studios. Thus there is an increasing demand for the enabling technology for distributed video production.

Problems of identifying phenolic compounds during the microbial degradation of olive mill wastewater
(1996)
Yams of the most widely differing nature are produced in textile mills. The production stages necessary for this are carried out with the aid of textile machines. Between these individual textile machines - from cards to spinning machines - sliver cans serve as a rule as transport containers, in which the sensitive sliver material is temporarily stored, and presented to the next production stage.
