  1. 1. Evaluating the use of clock frequency ratio estimators in the playout from video distribution networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Emil Myresten; [2023]
    Keywords : Clock Frequency Ratio Estimator; Real-time Transport Protocol; RTP; Video Distribution Network; Playout Scheduling; Clock Skew; Clock Synchronization; Uppskattning av klockfrekvensratio; Real-time Transport Protocol; RTP; Distributionsnätverk för video; Utspelningsschemaläggare; Klockskevning; Klocksynkronisering;

    Abstract : As traditional TV-broadcasters utilize the Internet to transport video streams, they often employ third party distribution networks to ensure that the Quality of Service of the packet stream remain high. In the last step of such a distribution network, a playout scheduler will schedule the packets so that their intervals are as close as possible to the intervals with which they were initially sent by the source.

  3. 2. Clear as a Bell : A sensory and aesthetic history of timekeeping and eco-social relations in Uppsala and the world

    University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

    Author : Isabel Inkpen; [2023]
    Keywords : Timescape; eco-social relations; time foraging; church bells; clocks; sensory history;

    Abstract : Methods of timekeeping have changed drastically throughout history and especially in the last century, as has humanity’s relationship to nature. Building upon existing research into the history of clocks and clock-time this study sketches a long-term chronology with a novel environmental, sensory, and aesthetic analysis. READ MORE

  4. 3. Time synchronization error detection in a radio access network

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Moulika Madana; [2023]
    Keywords : GNSS - Global Navigation Satellite System; OAS - Over-the air-synchronization; PRTC - primary reference time clock; PTP - precision time protocol; Gauss Jordan elimination; GNN- Graph Neural Network; GNSS -Globalt navigationssatellitsystem; OAS - Över-the-air tidssynkronisering; PRTC - Primär referenstidklocka; PTP - Precisionstidprotokoll; Gauss Jordan eliminering; GNN- Graf neurala nätverk;

    Abstract : Time synchronization is a process of ensuring all the time difference between the clocks of network components(like base stations, boundary clocks, grandmasters, etc.) in the mobile network is zero or negligible. It is one of the important factors responsible for ensuring effective communication between two user-equipments in a mobile network. READ MORE

  5. 4. Verification Method for Time of Capture of a Rolling Shutter Image

    University essay from Linköpings universitet/Databas och informationsteknik

    Author : Filip Johansson; Alexander Johansson; [2023]
    Keywords : Verification method; rolling shutter; image timestamp; camera systems; mapping study; automotive;

    Abstract : Modern automotive systems increasingly depend on camera sensors to gather safetycriticaldata used in driver-assisting features of the system. These features can consist offor example, lane-keeping assist and automatic braking where the sensors register objectswithin certain distances. READ MORE

  6. 5. TSN Distributed Clock : An analysis of relationships between network configuration parameters and the resulting precision of time synchronization

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jakob Götberg; Jakob Olsson; [2023]
    Keywords : Time Sensitive Networking TSN ; IEEE 802.1AS; Ethernet; Time Aware Shaper TAS ; Real-time Communication; Time Sensitive Networking TSN ; IEEE 802.1AS; Ethernet; Time Aware Shaper TAS ; Realtids kommunikation;

    Abstract : In real-time systems spanning a network, there is a need for deterministic communication. The best-effort approach which most of the Internets traffic follows is not suitable for this area since it does not guarantee packet delivery within a deadline and there is also no accurate measure of when the packet was sent.
