  1. 1. Towards Video Secure Streaming - Feasibility Study of Using an Obscuring Algorithm in Conjunction of H.264 Encoding and Compression

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för teknik och estetik

    Författare :Deepika Challa; Surya Teja Vulavakayala; [2021]
    Nyckelord :H.264 codecs; H.264; video streaming; security in video streaming;

    Sammanfattning : Technology advancement increases the usage of the internet day by day. One of the most used internet services is video streaming. The major advantage of video streaming is that it allows long distance communication between people without any delay. LÄS MER

  3. 2. Audio Detection for Preparation of Video Rate Controller

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Olle Axelsson; Tobias Bladh; [2021]
    Nyckelord :Audio detection; Gaussian Mixture Model; GMM; Video Rate Control; Rate Control; Video Streaming; Technology and Engineering;

    Sammanfattning : Modern video streaming may use the protocol H.264 to encode video in high quality. The protocol takes advantage of similarities between consecutive frames to lower the bit rate. If there are differences between frames the bit rate will therefore rise. LÄS MER

  4. 3. Recording Rendering API Commands for Instant Replay : A Runtime Overhead Comparison to Real-Time Video Encoding

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Marcus Holmberg; [2020]
    Nyckelord :Instant Replay; Command Recording; Real-time Rendering; Real-time Video Encoding; Återspelning; Kommandoinspelning; Realtidsrendering; Videokodning i Realtid;

    Sammanfattning : Background. Instant replay allows an application to highlight events without exporting a video of the whole session. Hardware-accelerated video encoding allows replay footage to be encoded in real-time with less to no impact on the runtime performance of the actual simulation in the application. LÄS MER

  5. 4. Characterizing Video Compression Using Convolutional Neural Networks

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Datavetenskap

    Författare :Sebastian Emmot; [2020]
    Nyckelord :Neural Networks; Image Analysis; Video Analysis; Compression; Deep Learning;

    Sammanfattning : Can compression parameters used in video encoding be estimated, given only the visual information of the resulting compressed video? If so, these parameters could potentially improve existing parametric video quality estimation models. Today, parametric models use information like bitrate to estimate the quality of a given video.

  7. 5. Performance Analysis of Large-scale Realtime Video Stream Configurations

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Erik Laurin; Joacim Eberlén; [2019-11-18]
    Nyckelord :Video coding; Encoding; Codecs; H.264; VP9; QSV; Intel QuickSync; Real-time encoding; SSIM; Autonomous driving; Bayesian Optimization;

    Sammanfattning : The rapid technology development has resulted in sensors able to deliver very high-quality output. The high quality calls for efficient compression algorithms to handle the vast amount of data produced. LÄS MER
