  1. 16. Video Conferencing - Session and Transmission Control

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för datavetenskap

    Författare :Marcus Carlberg; Christoffer Stengren; [2015]
    Nyckelord :Video conference; Media streaming; Network congestion control; h.264; TCP-CUBIC; TCP-CUBIC-FIT; TCP-Illinois; GStreamer; Technology and Engineering;

    Sammanfattning : Video conferencing is a very bandwidth sensitive application, if the available bandwidth is to low to handle the send rate of the media, packages will be lost in the network and thus the conference will be disrupted. Axis Communications would like to know which techniques are used today to ensure optimized bandwidth usage and as good quality as possible during a video conference even if the network bandwidth changes.

  3. 17. Prestanda och precision på en enkortsdator i ett system med realtidskrav

    Kandidat-uppsats, Högskolan i Jönköping/JTH, Data- och elektroteknik

    Författare :Torbjörn Wikman; Philip Hassel; [2014]
    Nyckelord :Kamerasystem; enkortsdator; Raspberry Pi; videosignal; CPU-användning; serverkommunikation; nätverkstrafik; Saab AB;

    Sammanfattning : The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.
