Internet telephony compression algorithms

IEEE WESCANEX 97 Communications, Power and Computing. Conference Proceedings, 2002
Internet telephony is the technology that allows for the transmission of digitized voice signals over the lnternet. The Internet telephony market has exploded since March of 1995 and continues to grow with the distribution of Internet telephone applications via the two leading Web browsers; Netscape Navigator and Internet Explorer. The technology needs

Internet phone — changing the telephony paradigm?

BT Technology Journal, 1997
This paper provides an overview of the history, current status, and underlying technology of ‘Internet telephony‘ — the transport of speech information over a packet-switched connectionless network. The economics of Internet telephony and a number of possible system architectures for interconnection with the switched telephone network are examined. The

A telephone adapter for Internet telephony systems

Microprocessors and Microsystems, 1997
Abstract In order to make the Internet telephony system a step closer to being a viable replacement of the conventional telephony system, an Internet telephone adapter (ITA) is proposed to interface a conventional telephone to the host computer. With the ITA, there is no longer the need for the current practice of using the host computer's microphone

Internet, lies and telephony

Telecommunications Policy, 1997
Abstract Despite warnings that Europe has been falling behind in its use and exploitation of information technologies, many policymakers there have been slow to comprehend the full potential of Internet and related developments. Some wish to tax it, while others have yet to realise the substantial impact it will have on many economic sectors or have ...

Dynamic bandwidth allocation for Internet telephony

Computer Communications, 2004
Internet telephony is promising for long-distance calls because of its low service charge and value-added functions. To provide Internet telephony to the general public, a service provider can operate a telephone gateway in each servicing city to bridge the local telephone network and the Internet, so that users can use telephones or fax machines to ...

Internet telephony and modem delay

IEEE Network, 1999
The vast majority of consumer Internet access is via dialup modems. These modems are a primary source of the delay experienced on voice over IP cells. The author focuses on understanding the causes of delay within analog modems, with the objective of developing recommendations to minimize delay for VoIP applications.

The Internet telephony red herring

Proceedings of GLOBECOM'96. 1996 IEEE Global Telecommunications Conference, 2002
The spectre of low-cost, real-time voice communication over the Internet has polarised Internet service providers and telephone network operators, at the expense of finding solutions to the problem of integrating communications services (in particular, existing wireless and wireline telephony) with WWW content services. This paper argues that solutions

Internet Telephony over Wireless Links

2006
Many telephony calls are carried over IP-based technologies, which include wireless systems such as WLAN, Hyperlan or Wimax. This thesis contains algorithms which reduce the overhead of IP-based speech communication. The aim is to increase the human perceived call quality while recognising communication standards defining Internet telephony and ...
