1. 1. Optimizing Genre-Based Video Transcoding for Low Bitrates

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Nicole Nordlund; [2023]
   Nyckelord :video quality; genre-based video transcoding; low bitrate; x265; videokvalité; genrebaserad videotranskodering; låg bithastighet; x265;

   Sammanfattning : A large portion of network resources is consumed by video traffic, and this increasing demand causes challenges in the area of video coding. As the expectations for high-quality video grow the required bitrate rises in accordance, which motivates research on lowering bitrates. LÄS MER

3. 2. Content Based Video Encoding Based on Spatial and TemporalInformation

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Theofanis Papakonstantinou; [2023]
   Nyckelord :;

   Sammanfattning : A significant amount of video content is produced today that needs to be stored, distributed, andstreamed globally in a cost-effective way. This relies on video compression, a process performedby encoding software that remove spatial redundancy, the similarities within a frame, andtemporal redundancy, the similarities between temporarily adjacent frames.

4. 3. Making Video Streaming More Efficient Using Per-Shot Encoding

   Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Douglas Gådin; Fanny Hermanson; Anton Marhold; Joel Sikström; Johan Winman; [2022]
   Nyckelord :per-shot encoding; video streaming; encoding; transcoding; per-shot kodning; videoströmmning; videokodning; transkodering;

   Sammanfattning : The demand for streaming high-quality video increases each year and the energy used by consumers is estimated to increase by 23% from 2020 to 2030. The largest contributor to this is increased data transmission. LÄS MER

5. 4. Hur upplevd videokvalitet påverkas av upplösning och bitrate

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Christoffer Eriksson; Jimmy Mäkinen; [2021]
   Nyckelord :Upplevd videokvalitet; bitrate; upplösning; videokomprimering; bildartefakter.;

   Sammanfattning : Streaming is currently the main method used to watch videos, and with this a significant portion of all Internet traffic is occupied by streaming. In order to efficiently store and transfer this large quantity of data, compression is necessary for the streaming services. LÄS MER

7. 5. Speeding up a mixed reality application: A study of two encoding algorithms

   Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Jesper Elgh; Ludvig Thor; [2020]
   Nyckelord :;

   Sammanfattning : Mixed reality (MR) or augmented reality (AR) is a way of combining the digital world with the real world. It is utilized in a number of different applications. The mobile devices of today may not always provide sufficient processing power to handle these kind of applications. LÄS MER
