WebRTC
WebRTC (Web Real-Time Communication) is a free and open-source project providing web browsers and mobile applications with real-time communication (RTC) via application programming interfaces (APIs). It allows audio and video communication and streaming to work inside web pages by allowing direct peer-to-peer communication, eliminating the need to install plugins or download native apps. Supported by Apple, Google, Microsoft, Mozilla, and Opera, WebRTC specifications have been published by the World Wide Web Consortium (W3C) and the Internet Engineering Task Force (IETF). History In May 2010, Google bought Global IP Solutions or GIPS, a VoIP and videoconferencing software company that had developed many components required for RTC, such as codecs and echo cancellation techniques. Google open-sourced the GIPS technology and engaged with relevant standards bodies at the IETF and W3C to ensure industry consensus. In May 2011, Google released an open-source project for ...

Videoconferencing
Videotelephony (also known as videoconferencing or video calling) is the use of audio signal, audio and video for simultaneous two-way communication. Today, videotelephony is widespread. There are many terms to refer to videotelephony. ''Videophones'' are standalone devices for video calling (compare Telephone). In the present day, devices like smartphones and computers are capable of video calling, reducing the demand for separate videophones. ''Videoconferencing'' implies group communication.Mulbach et al, 1995. pg. 291. Videoconferencing is used in telepresence, whose goal is to create the illusion that remote participants are in the same room. The concept of videotelephony was conceived in the late 19th century, and versions were available to the public starting in the 1930s. Early demonstrations were installed at booths in post offices and shown at various world expositions. In 1970, AT&T launched the first commercial personal videotelephone system. In addition to videoph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Real-time Communication
Real-time communication (RTC) is a category of software protocols and communication hardware media that gives real-time guarantees, which is necessary to support real-time guarantees of real-time computing. Real-time communication Protocols (computing), protocols are dependent not only on the Data integrity, validity and integrity of data transferred but also the timeliness of the transfer. Real-time communication systems are generally understood as one of two types: ''Hard Real-Time (HRT)'' and ''Soft Real-Time (SRT)''. The difference between a hard and soft real-time communication system is the consequences of incorrect operation. Safety-critical systems capable of causing catastrophic consequences upon a fault, such as Fly-by-wire, aircraft fly-by-wire systems, are designated as hard real-time, whereas non-critical but ideally real-time systems, such as hotel reservation systems, are designated as soft real-time. The designation of a real-time communication system as hard or sof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global IP Solutions
Global IP Solutions (also known as GIPS) was a United States–based corporation that developed real-time voice and video processing software for Internet Protocol, IP networks, before it was acquired by Google in May 2010. The company delivered embedded software that enabled real-time communications capabilities for video and voice over IP (VoIP). GIPS was perhaps best known for developing the narrowband iLBC and wideband audio, wideband internet Speech Audio Codec, iSAC speech codecs. GIPS software was generally delivered as “engines” that packaged together voice and video processing components for smoother integration and better performance. GIPS’ customers are primarily service providers, application developers, and manufacturers of IP phones, gateways or voice and video conferencing systems. History The company (formerly known as Global IP Sound) was founded in July 1999 in Stockholm, Sweden, by signal processing experts Roar Hagen (then GIPS’ CTO) and Bastiaan Klei ...

Internet Privacy
Internet privacy involves the right or mandate of personal privacy concerning the storage, re-purposing, provision to third parties, and display of information pertaining to oneself via the Internet. Internet privacy is a subset of data privacy. Privacy concerns have been articulated from the beginnings of large-scale computer sharing and especially relate to mass surveillance. Privacy can entail either personally identifiable information (PII) or non-PII information such as a site visitor's behavior on a website. PII refers to any information that can be used to identify an individual. For example, age and physical address alone could identify who an individual is without explicitly disclosing their name, as these two parameters are unique enough to identify a specific person typically. Other forms of PII may include GPS tracking data used by apps, as the daily commute and routine information can be enough to identify an individual. It has been suggested that the "appeal of o ...

WebSocket
WebSocket is a computer communications protocol, providing a full-duplex, simultaneous two-way communication channel over a single Transmission Control Protocol (TCP) connection. The WebSocket protocol was standardized by the Internet Engineering Task Force, IETF as in 2011. The current specification allowing web applications to use this protocol is known as ''WebSockets''. It is a living standard maintained by the Web Hypertext Application Technology Working Group, WHATWG and a successor to ''The WebSocket API'' from the World Wide Web Consortium, W3C. WebSocket is distinct from HTTP used to serve most webpages. Although they are different, states that WebSocket "is designed to work over HTTP ports 443 and 80 as well as to support HTTP proxies and intermediaries", thus making it compatible with HTTP. To achieve compatibility, the WebSocket Handshake (computing), handshake uses the HTTP/1.1 Upgrade header, HTTP Upgrade header to change from the HTTP protocol to the WebSocket pro ...

Voice Over IP
Voice over Internet Protocol (VoIP), also known as IP telephony, is a set of technologies used primarily for voice communication sessions over Internet Protocol (IP) networks, such as the Internet. VoIP enables voice calls to be transmitted as data packets, facilitating various methods of voice communication, including traditional applications like Skype, Microsoft Teams, Google Voice, and VoIP phones. Regular telephones can also be used for VoIP by connecting them to the Internet via analog telephone adapters (ATAs), which convert traditional telephone signals into digital data packets that can be transmitted over IP networks. The broader terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the delivery of voice and other communication services, such as fax, SMS, and voice messaging, over the Internet, in contrast to the traditional public switched telephone network (PSTN), commonly known as plain old telephone service (POTS) ...

Mobile Application
A mobile application or app is a computer program or software application designed to run on a mobile device such as a phone, tablet, or watch. Mobile applications often stand in contrast to desktop applications which are designed to run on desktop computers, and web applications which run in mobile web browsers rather than directly on the mobile device. Apps were originally intended for productivity assistance such as email, calendar, and contact databases, but the public demand for apps caused rapid expansion into other areas such as mobile games, factory automation, GPS and location-based services, order-tracking, and ticket purchases, so that there are now millions of apps available. Many apps require Internet access. Apps are generally downloaded from app stores, which are a type of digital distribution platforms. The term "app", short for " application", has since become very popular; in 2010, it was listed as " Word of the Year" by the American Dialect Society. Ap ...

Communication Protocol
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any variation of a physical quantity. The protocol defines the rules, syntax, semantics (computer science), semantics, and synchronization of communication and possible Error detection and correction, error recovery methods. Protocols may be implemented by Computer hardware, hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses predetermined for that particular situation. The specified behavior is typically independent of how it is to be Implementation, implemented. Communication protocols have to be agreed upon by the parties involved. To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, so there ...
