An adaptive bitrate switching algorithm for speech applications in the context of WebRTC
Alahmadi, Mohannad (NUI Galway, 2020-12-01)Web Real-time Communication (WebRTC) provides a set of novel technologies and standards that enable high-quality audio, video, conference calls, and arbitrary data exchange over web browsers. It enables peer-to-peer ... -
An analysis of the impact of playout delay adjustments introduced by voip jitter buffers on listening speech quality
Počta, Peter; Melvin, Hugh; Hines, Andrew (S. Hirzel Verlag, 2015-05-01)This paper investigates the impact of frequent and small playout delay adjustments (time-shifting) of 30 ms or less introduced to silence periods by Voice over IP (VoIP) jitter buffer strategies on listening quality perceived ... -
Improved techniques for time synchronisation over WiFi and wireless sensor networks
Shannon, Jonathan (2013-10-23)Time synchronisation plays a key and ever increasing role in this progressively networked world. Whilst time synchronisation has always been important in industrial and telecommunication systems, its importance has now ... -
Next generation HBBTV services and applications through multimedia synchronisation
Yuste, Lourdes Beloqui (2015-09-18)In this thesis, the focus is on multi-source, multi-platform media synchronisation on a single device. Multimedia synchronisation is a broad research area with many facets across many multimedia application types. With ... -
Optimizing the QoS of VoIP applications over WiFi through use of synchronized time
O Flaithearta, Padraig (2015-01-31)With a rapidly increasing volume of Internet content and connected devices, along with the development of cloud services and server virtualization, it's becoming clear that traditional network architectures are becoming ... -
Synchronization Issues for Smart Grids
Corcoran, Peter M.; Melvin, Hugh (2011)The loss of time synchronization across a Smart Grid due to local A/D and D/A conversion processes between the digital domain and the analogue control domain is considered. It is shown that a local calibration can ... -
