An electrical telegraph was a point-to-point text messaging system, used from the 1840s until the mid 20th century when it was slowly replaced by other telecommunication systems. At the sending station switches connected a source of current to the telegraph wires. At the receiving station the current activated electromagnets which moved indicators, providing either a visual or audible indication of the text. It was the first electrical telecommunications system and the most widely used of a number of early messaging systems called telegraphs, that were devised to communicate text messages more rapidly than by physical transportation. Prior to the electric telegraph, semaphore systems were used, including beacons, smoke signals, flag semaphore, and optical telegraphs for visual signals to communicate over distances of land.
A set-top box (STB), also colloquially known as a cable box and historically television decoder, is an information appliance device that generally contains a TV-tuner input and displays output to a television set and an external source of signal, turning the source signal into content in a form that can then be displayed on the television screen or other display device. They are used in cable television, satellite television, and over-the-air television systems as well as other uses.
Portugal has a modern and flexible telecommunications market and a wide range of varied media organisations. The regulatory body overseeing communications is called ANACOM.
Wireless local loop (WLL), is the use of a wireless communications link as the "last mile / first mile" connection for delivering plain old telephone service (POTS) or Internet access to telecommunications customers. Various types of WLL systems and technologies exist.
Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable television (CATV) system. It is used by many cable television operators to provide Internet access over their existing hybrid fiber-coaxial (HFC) infrastructure. The version numbers are sometimes prefixed with simply "D" instead of "DOCSIS".
ZTV was a Swedish television channel owned by Viasat. Launched in February 1991, as a daily afternoon show on TV3 and TV4, it became a channel of its own on Swedish cable networks in May 1992. The intention was to create a Swedish version of MTV and thus the focus was primarily on music. Since May 2006, most of its programming consisted of music videos. ZTV's last day was August 1, 2010 for all customers except for Boxer and Com Hem, who continued to distribute the channel indefinitely in a limited version. MTG's new sports channel TV10 took over the transmissions of other operators.
WiMAX is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide multiple physical layer (PHY) and Media Access Control (MAC) options.
KDDI Corporation is a Japanese telecommunications operator formed on October 1, 2000 through the merger of DDI Corp., KDD Corp., and IDO Corp. It has its headquarters in the Garden Air Tower in Iidabashi, Chiyoda, Tokyo.
Internet Protocol television (IPTV) is the delivery of television content over Internet Protocol (IP) networks. This is in contrast to delivery through traditional terrestrial, satellite, and cable television formats. Unlike downloaded media, IPTV offers the ability to stream the source media continuously. As a result, a client media player can begin playing the content almost immediately. This is known as streaming media.
CableCARD is a special-use PC Card device that allows consumers in the United States to view and record digital cable television channels on digital video recorders, personal computers and television sets on equipment such as a set-top box not provided by a cable television company. The card is usually provided by the local cable operator, typically for a nominal monthly fee.
The next-generation network (NGN) is a body of key architectural changes in telecommunication core and access networks. The general idea behind the NGN is that one network transports all information and services by encapsulating these into IP packets, similar to those used on the Internet. NGNs are commonly built around the Internet Protocol, and therefore the term all IP is also sometimes used to describe the transformation of formerly telephone-centric networks toward NGN.
In telecommunications, triple play service is a marketing term for the provisioning, over a single broadband connection, of two bandwidth-intensive services, broadband Internet access and television, and the latency-sensitive telephone. Triple play focuses on a supplier convergence rather than solving technical issues or a common standard. However, standards like G.hn might deliver all these services on a common technology.
Hathway Cable & Datacom Ltd, formerly BITV Cable Networks, is an Indian cable television service operator based in Mumbai. It was the first company to provide Internet using the CATV network in India, and the first cable operator to launch a digital platform in 2006. Hathway Broadband Internet was the first cable ISP in India. Business India Television (BITV) Cable Networks Pvt Ltd was acquired by Hathway in 1999. As of 2007, the company had a 51% stake in Bhupendran Bhaskar Multinet and 50% stake in Gujarat Telelinks Pvt Ltd (GTPL). In 2011, Hathway GTPL entered in Assam with a MoM with V&S Cable Pvt Ltd, and started operations in West Bengal as they acquired KCBPL to create a subsidiary - GTPLKCBPL, responsible for providing services in West Bengal.
Fiber to the x or fiber in the loop is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. As fiber optic cables are able to carry much more data than copper cables, especially over long distances, copper telephone networks built in the 20th century are being replaced by fiber.
In a hierarchical telecommunications network, the backhaul portion of the network comprises the intermediate links between the core network, or backbone network, and the small subnetworks at the edge of the network.
TV3 is a Swedish pay television channel owned by Nordic Entertainment Group. It was launched on 31 December 1987 by businessman Jan Stenbeck.
In telecommunications, a femtocell is a small, low-power cellular base station, typically designed for use in a home or small business. A broader term which is more widespread in the industry is small cell, with femtocell as a subset. It connects to the service provider's network via broadband ; current designs typically support four to eight simultaneously active mobile phones in a residential setting depending on version number and femtocell hardware, and eight to sixteen mobile phones in enterprise settings. A femtocell allows service providers to extend service coverage indoors or at the cell edge, especially where access would otherwise be limited or unavailable. Although much attention is focused on WCDMA, the concept is applicable to all standards, including GSM, CDMA2000, TD-SCDMA, WiMAX and LTE solutions.
Broadband is a term normally considered to be synonymous with a high-speed connection to the internet. Suitability for certain applications, or technically a certain quality of service, is often assumed. For instance, low round trip delay would normally be assumed to be well under 150ms and suitable for Voice over IP, online gaming, financial trading especially arbitrage, virtual private networks and other latency-sensitive applications. This would rule out satellite Internet as inherently high-latency. In some applications, utility-grade reliability or security are often also assumed or defined as requirements. There is no single definition of broadband and official plans may refer to any or none of these criteria.
i3 Broadband is an American pay television and telecommunications provider set in Rhode Island. It is the third-largest cable television and Internet service provider in the state.
