  1. 1. Live Mobile Video Interaction : Inventing and investigating technology, formats and applications

    Författare :Mudassar Ahmad Mughal; Oskar Juhlin; Gina Venolia; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; human computer interaction; liveness; live; ambient video; mobile webcasting; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : The convergence of inexpensive video-enabled mobile phones, high-speed mobile data networks and ubiquitous sensing devices opens up a new design space called “live mobile video interaction”. It gives rise to a new genre of applications concerning live mobile video production, which can be seen as an instance of the said space. LÄS MER

  2. 2. Digital Distance Education – A Longitudinal Exploration of Video Technology

    Författare :Lena Dafgård; Göteborgs universitet; Göteborgs universitet; Gothenburg University; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; NATURVETENSKAP; distance education; digitalisation; video; higher education;

    Sammanfattning : The context of this thesis is digital distance education. Distance education has developed from correspondence courses, based on letters sent by mail between student and teacher, to digital distance education with interactive video classes from anywhere, as long as a computer/tablet/smartphone and an Internet connection are available.

    Sammanfattning : This thesis explores social and creative practices that emerge with new mobile video technology. The work frames a design space that spans across both the social and technical domains. LÄS MER

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

    Författare :Mathias Johanson; Chalmers University of Technology; []
    Nyckelord :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

  5. 5. Efficient multicast video streaming over heterogeneous networks

    Författare :Patrik Österberg; Mittuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; multicast; fairness; video; Computer science; Datavetenskap;

    Sammanfattning : The demand for real-time video streaming over Internet is ever growing. The aggregated bandwidth of the video flows can be substantial, which motivates the use of bandwidth-preserving techniques such as multicast transmission and powerful source coding algorithms. LÄS MER
