1. 1. Supporting Video-mediated Communication over the Internet

   Författare :Mathias Johanson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; layered multicast; distributed collaborative work; layered video coding; robust video transmission; Internet video; video gateways; video-mediated communication; congestion control; teleconferencing; stereoscopic video;

   Sammanfattning : The tremendous success of the Internet in providing a global communication infrastructure for a wide variety of applications has inspired the invention of packet video systems for synchronous interpersonal communication. The potential benefits of video-mediated communication are numerous, ranging from improved social interactions between individuals to more efficient distributed collaborative work. LÄS MER

3. 2. Teleconferencing, system identification and array processing

   Författare :Per Åhgren; Peter Stoica; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling;

   Sammanfattning : The area of teleconferencing has long yielded great interest in the signal processing community. The main reasons for this are probably the huge interest from the industry and the challenging problems of the topic. The problems of teleconferencing are relevant for several different disciplines in signal processing. LÄS MER

4. 3. An analysis of the dynamics of multidisciplinary medical team meetings and the use of communication technology

   Författare :Bridget Kane; Ireland Trinity College University of Dublin; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; CSCW; HCI; MDT; Decision making; MDTM; Teamwork; Information Systems; Informatik;

   Sammanfattning : Multidisciplinary medical team meetings (MDTM)s are collaborative fora where healthcare spe- cialists come together to discuss patient cases, establish a definitive diagnosis and determine the best treatment strategy for the patient. The practice of MDTMs is growing in importance as regulatory agencies advocate their adoption into routine practice. LÄS MER

   Sammanfattning : During face-to-face meetings, humans use multimodal information, including verbal information, visual information, body language, facial expressions, and other non-verbal gestures. In contrast, during computer-mediated-communication (CMC), humans rely either on mono-modal information such as text-only, voice-only, or video-only or on bi-modal information by using audiovisual modalities such as video teleconferencing.

7. 5. Security and Efficiency Tradeoffs in Multicast Group Key Management

   Författare :Claudiu Duma; Nahid Shahmehri; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Key management; Multicast communication; Security-efficiency tradeoffs; Collusion resistance; Push-oriented approaches; Computer science; Datavetenskap;

   Sammanfattning : An ever-increasing number of Internet applications, such as content and software distribution, distance learning, multimedia streaming, teleconferencing, and collaborative workspaces, need efficient and secure multicast communication. However, efficiency and security are competing requirements and balancing them to meet the application needs is still an open issue. LÄS MER
