Very Small Aperture Terminals (VSATs)

John Everett

The Institution of Engineering and Technology, 1992

One of the most significant developments in telecommunications in the last decade, the very small aperture terminal (VSAT), as part of a satellite communications network, is the culmination of technology that allows earth terminals to be located on users' premises to provide data, voice and even video services. Networks based on VSATs can be established rapidly and reconfigured to respond to changing communications needs in a flexible and cost-effective manner.

Video Compression Systems

From first principles to concatenated codecs

Alois M. Bock

The Institution of Engineering and Technology, 2009

Digital video compression has revolutionised the broadcast industry. Its implementation has been the vital key to the expansion of video via satellite, cable, internet and terrestrial TV. However, new technologies not only enable new applications, they also create new challenges such as how to measure video quality, and how to maintain video quality in concatenated compression systems.

Voice Biometrics

Technology, trust and security

Carmen García-Mateo

The Institution of Engineering and Technology, 2021

Voice biometrics are being implemented globally in large scale applications such as remote banking, government e-services, transportation and building security access, autonomous vehicles, and healthcare. They have been integrated in numerous apps, often coupled with face biometrics and artificial intelligence methods. Voice biometrics products and solutions must meet three key requirements for the success in their deployment: they must be highly trustable regarding privacy protection; easy to use and always be available.

Voice Over IP (Internet Protocol)

Systems and solutions

Richard Swale

The Institution of Engineering and Technology, 2001

Voice over Internet Protocol (VoIP) has recently evolved from a simple capability for transporting voice communications into a much more powerful technology capable of changing the way voice applications are constructed, delivered, marketed and sold. Whilst VoIP has clearly provided a focus for much debate within the telecommunications industry, there has been a clear gulf between hype and reality. However the questions now being asked have migrated from 'Will it work?' to 'What will the industry look like when it is delivered at scale?'
