UDcast was a company that provided products for Internet Protocol (IP) over broadcast media. It developed technology for IP networks over satellite and servers to provide television on mobile networks.

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet.

Satellite Human-made object put into an orbit

In the context of spaceflight, a satellite is an object that has been intentionally placed into orbit. These objects are called artificial satellites to distinguish them from natural satellites such as Earth's Moon.

History

UDcast was involved in international standards organisations such as ETSI and the Internet Engineering Task Force. UDcast was founded in June 2000 by members of the INRIA research center who had helped develop Unidirectional Link Routing (the UD stands for unidirectional, and the cast for broadcast). The mechanism was published in 2001 as number 3077 in the Request for Comments series. [1] Founders included Antoine Clerget, Patrick Cipière, Emmanuel Duros, and Luc Ottavj. [2] From at least 2003 through 2007, Hubert Zimmermann served as chief executive officer. [3] [4] [5]

ETSI nonprofit european standards organization

The European Telecommunications Standards Institute (ETSI) is an independent, not-for-profit, standardization organization in the telecommunications industry in Europe, headquartered in Sophia-Antipolis, France, with worldwide projection. ETSI produces globally-applicable standards for Information and Communications Technologies (ICT), including fixed, mobile, radio, converged, broadcast and internet technologies.

Internet Engineering Task Force organization

The Internet Engineering Task Force (IETF) is an open standards organization, which develops and promotes voluntary Internet standards, in particular the standards that comprise the Internet protocol suite (TCP/IP). It has no formal membership or membership requirements. All participants and managers are volunteers, though their work is usually funded by their employers or sponsors.

Request for Comments (RFC), in information and communications technology, is a type of text document from the technology community. An RFC document may come from many bodies including from the Internet Engineering Task Force (IETF), the Internet Research Task Force (IRTF), the Internet Architecture Board (IAB), or from independent authors. The RFC system is supported by the Internet Society (ISOC).

UDcast marketed wide-area network optimization appliances optimized for satellite infrastructures, with optimizations targeted at some specific satellite markets. They used acronyms such as DVB-H, DVB-SH, ATSC and WiMAX.

WAN optimization is a collection of techniques for increasing data transfer efficiencies across wide-area networks (WANs). In 2008, the WAN optimization market was estimated to be $1 billion, and was to grow to $4.4 billion by 2014 according to Gartner, a technology research firm. In 2015 Gartner estimated the WAN optimization market to be a $1.1 billion market.

DVB-H is one of three prevalent mobile TV formats. It is a technical specification for bringing broadcast services to mobile handsets. DVB-H was formally adopted as ETSI standard EN 302 304 in November 2004. The DVB-H specification can be downloaded from the official DVB-H website. From March 2008, DVB-H is officially endorsed by the European Union as the "preferred technology for terrestrial mobile broadcasting". The major competitors of this technology are Qualcomm's MediaFLO system, the 3G cellular system based MBMS mobile-TV standard, and the ATSC-M/H format in the U.S. DVB-SH now and DVB-NGH in the future are possible enhancements to DVB-H, providing improved spectral efficiency and better modulation flexibility. DVB-H has been a commercial failure, and the service is no longer on-air. Ukraine was the last country with a nationwide broadcast in DVB-H.

DVB-SH is a physical layer standard for delivering IP based media content and data to handheld terminals such as mobile phones or PDAs, based on a hybrid satellite/terrestrial downlink and for example a GPRS uplink. The DVB Project published the DVB-SH standard in February 2007.

On 3 February 2011 OneAccess Networks announced they completed the acquisition of UDCast. [6]

History of the Internet History of the Internet, a global system of interconnected computer networks

The history of the Internet has its origin in the efforts of wide area networking that originated in several computer science laboratories in the United States, United Kingdom, and France. The U.S. Department of Defense awarded contracts as early as the 1960s, including for the development of the ARPANET project, directed by Robert Taylor and managed by Lawrence Roberts. The first message was sent over the ARPANET in 1969 from computer science Professor Leonard Kleinrock's laboratory at University of California, Los Angeles (UCLA) to the second network node at Stanford Research Institute (SRI).

Multicast a computer networking technique for forwarding transmissions from one sender to multiple receivers

In computer networking, multicast is group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution. Multicast should not be confused with physical layer point-to-multipoint communication.

Set-top box information appliance device

A set-top box (STB), also colloquially known as a set-top unit (STU), cable box (CB) or stream box (SB), 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.

In computing, Internet Key Exchange is the protocol used to set up a security association (SA) in the IPsec protocol suite. IKE builds upon the Oakley protocol and ISAKMP. IKE uses X.509 certificates for authentication ‒ either pre-shared or distributed using DNS ‒ and a Diffie–Hellman key exchange to set up a shared session secret from which cryptographic keys are derived. In addition, a security policy for every peer which will connect must be manually maintained.

Satellite Internet access is Internet access provided through communications satellites. Modern consumer grade satellite Internet service is typically provided to individual users through geostationary satellites that can offer relatively high data speeds, with newer satellites using Ku band to achieve downstream data speeds up to 506 Mbit/s.

DVB-S2

Digital Video Broadcasting - Satellite - Second Generation (DVB-S2) is a digital television broadcast standard that has been designed as a successor for the popular DVB-S system. It was developed in 2003 by the DVB Project, an international industry consortium, and ratified by ETSI in March 2005. The standard is based on, and improves upon DVB-S and the electronic news-gathering system, used by mobile units for sending sounds and images from remote locations worldwide back to their home television stations.

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.

Datacasting is the broadcasting of data over a wide area via radio waves. It most often refers to supplemental information sent by television stations along with digital terrestrial television, but may also be applied to digital signals on analog TV or radio. It generally does not apply to data which is inherent to the medium, such as PSIP data which defines virtual channels for DTT or direct broadcast satellite systems; or to things like cable modem or satellite modem, which use a completely separate channel for data.

Hubert Zimmermann was a French software engineer and a pioneer of computer networking.

The Unidirectional Lightweight Encapsulation (ULE) is a Data link layer protocol for the transportation of network layer packets over MPEG transport streams.

IP over DVB or IP over MPEG implies that Internet Protocol datagrams are transferred over the MPEG transport stream, and are distributed using some digital television system, for example DVB-H, DVB-T, DVB-S or DVB-C.

Multiprotocol Encapsulation, or MPE for short, is a Data link layer protocol defined by DVB which has been published as part of ETSI EN 301 192. It provides means to carry packet oriented protocols on top of MPEG transport stream (TS).

Hybrid Broadcast Broadband TV

Hybrid Broadcast Broadband TV (HbbTV) is both an industry standard and promotional initiative for hybrid digital TV to harmonise the broadcast, IPTV, and broadband delivery of entertainment to the end consumer through connected TVs and set-top boxes. The HbbTV Association, comprising digital broadcasting and Internet industry companies, has established a standard for the delivery of broadcast TV and broadband TV to the home, through a single user interface, creating an open platform as an alternative to proprietary technologies. Products and services using the HbbTV standard can operate over different broadcasting technologies, such as satellite, cable, or terrestrial networks.

Sat-IP

SAT>IP specifies a IP-based Client-Server communication protocol for a TV gateway in which SAT>IP servers, connected to one or more DVB broadcast sources, send the program selected and requested by an SAT>IP client over an IP based local area network in either unicast for the one requesting client or multicast in one datastream for several SAT>IP clients.

A Uniform Resource Locator (URL), colloquially termed a web address, is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier (URI), although many people use the two terms interchangeably. Thus http://www.example.com is a URL, while www.example.com is not.</ref> URLs occur most commonly to reference web pages (http), but are also used for file transfer (ftp), email (mailto), database access (JDBC), and many other applications.
