Problem description: | Norway has specific challenges when it comes to video communication. Though the land-based infrastructure is sufficient to places where people live, communication to re-creational and remote sites is challenging. The mobile network is heavily used for video today, and the usage is expected to increase. A second scenario is based on the operational challenges for environmental monitoring in Norway as a whole, and specifically in the Northern areas. The ocean area belonging to Norway is roughly 7-times as large as the land area, and a large amount of this area is located in the far North. The only way to establish communication therer is through satellite links. Satellite links from geostationary satellites suffer from the low elevation, leading to signal outage (scintillation). Thus providing video communicating in the North is a challenge.
This thesis will provide a survey over challenges being identified in scientific literature in this area of video communication. The main goal of the survey is to identify best practices, and areas for improvement of the video communication. Based on the survey, a specific callenge is identified, and a test-bad will be implemented to achieve hands-on experience. The latter part of the thesis will then identify methods to enhance/optimize the solution. |

Pre-Knowledge | The thesis will focus on an implementation of quality mechanisms for video streaming, thus the applicant should have a a pre-knowledge on video codecs. As thin pipes are typically seen in wireless/mobile environments, the author should also have some knowledge in the field of "radio". |

Motivation
- video over satellite
- Nordområdet
- geostationary satellites: scintillation in the atmosphere
- Norge: 7 times as much sea surface as land surface
Problemstillingen
- which possibilities are there to provide video over satellite?
- how do the parameter fit relate to pre-knowledge of the satellite link?
- "real-time" calculation and optimisation
Survey
Start with a survey
- Video over Satcom (kommersielle løsninger i militære samarbeid)
- Buffer size, parameter setting, codecs
- varying and thin pipe
- 15-20 scientific paper to start with (Google scholar or Microsoft Academics), se Search_for_literature
