ToIP
Text over IP (or ToIP) is a means of providing a real-time text (RTT) service that operates over IP-based networks. It complements Voice over IP (VoIP) and Video over IP. Real-time text is streaming text that is transmitted as it is produced, allowing text to be used conversationally. Real-time text is defined in ITU-T Multimedia Recommendation F.700 2.1.2.1 . Real-time text is designed for conversational use where people interactively converse with each other. To achieve this, particular user requirements have been specified for the delay of each character and the character loss rate (see F.700 Annex A.3). Real-time Text over IP can be used: *in conjunction with voice or video in a multimedia communication or on its own, on fixed or mobile accesses, * by people who want a fast and really interactive means of conversing, * in noisy environments where it may be hard to hear, * in environments where other people are nearby but where communications privacy is required, * to transfer ...

Real-time Text
Real-time text (RTT) is text messaging, text transmitted instantly as it is typed or created. Recipients can immediately read the message while it is being written, without waiting. Real-time text is used for conversational text, in collaboration, and in live captioning. Technologies include TDD/TTY devices for the deaf, live captioning for TV, Text over IP (ToIP), some types of instant messaging, captioning for telephony/video teleconferencing, telecommunications relay services including ip-relay, transcription services including Remote CART, TypeWell, Collaborative real-time editing, collaborative text editing, Stream (computing), streaming text applications, Next Generation 9-1-1, next-generation 9-1-1/1-1-2 emergency service. Obsolete TDD/TTY devices are being replaced by more modern real-time text technologies, including Text over IP, ip-relay, and instant messaging. During 2012, the Real-Time Text Taskforce (R3TF) designed a standard international symbol to represent real-tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telecommunications Relay Service
A telecommunications relay service, also known as TRS, relay service, or IP-relay, or Web-based relay service, is an operator service that allows people who are deaf, hard of hearing, deafblind, or have a speech disorder to place calls to standard telephone users via a keyboard or assistive device. Originally, relay services were designed to be connected through a TDD, teletypewriter (TTY) or other assistive telephone device. Services gradually have expanded to include almost any real-time text capable technology such as a personal computer, laptop, mobile phone, PDA, and many other devices. The first TTY was invented by deaf scientist Robert Weitbrecht in 1964. The first relay service was established in 1974 by Converse Communications of Connecticut. Types of services available Depending on the technical and physical abilities and physical environments of users, different call types are possible via relay services.

Telecommunications Device For The Deaf
A telecommunications device for the deaf (TDD) is a teleprinter, an electronic device for text communication over a telephone line, that is designed for use by persons with hearing or speech difficulties. Other names for the device include teletypewriter (TTY), textphone (common in Europe), and minicom (United Kingdom). The typical TDD is a device about the size of a typewriter or laptop computer with a QWERTY keyboard and small screen that uses an LED, LCD, or VFD screen to display typed text electronically. In addition, TDDs commonly have a small spool of paper on which text is also printedold versions of the device had only a printer and no screen. The text is transmitted live, via a telephone line, to a compatible device, i.e. one that uses a similar communication protocol. Special telephone services have been developed to carry the TDD functionality even further. In certain countries, there are systems in place so that a deaf person can communicate with a hearing person ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PSTN
The public switched telephone network (PSTN) provides infrastructure and services for public telecommunication. The PSTN is the aggregate of the world's circuit-switched telephone networks that are operated by national, regional, or local telephony operators. These consist of telephone lines, fiber optic cables, microwave transmission links, cellular networks, communications satellites, and undersea telephone cables, all interconnected by switching centers which allow most telephones to communicate with each other. Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital in its core network and includes mobile and other networks, as well as fixed telephones. The technical operation of the PSTN adheres to the standards created by the ITU-T. These standards allow different networks in different countries to interconnect seamlessly. The E.163 and E.164 standards provide a single global address space for telephone numbers. The combinat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Videophone
Videotelephony, also known as videoconferencing and video teleconferencing, is the two-way or multipoint reception and transmission of audio and video signals by people in different locations for real time communication.McGraw-Hill Concise Encyclopedia of EngineeringVideotelephony McGraw-Hill, 2002. Retrieved from the FreeDictionary.com website, January 9, 2010 A videophone is a telephone with a video camera and video display, capable of simultaneous video and audio communication. Videoconferencing implies the use of this technology for a group or organizational meeting rather than for individuals, in a videoconference.Mulbach et al, 1995. pg. 291. Telepresence may refer either to a high-quality videotelephony system (where the goal is to create the illusion that remote participants are in the same room) or to meetup technology, which can go beyond video into robotics (such as moving around the room or physically manipulating objects). Videoconferencing has also been called "visu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IpTTY
ipTTY is a SIP soft phone that supports the conversion of Baudot Tones sent via IP to text. In other words, ipTTY facilitates a TTY/TDD conversation over IP without the need for modems or analog lines. ipTTY connects directly via IP to PBX and VoIP systems that support SIP. This type of communication is necessary for individuals with hearing impairments. Additionally, both the ADA (Americans with Disabilities Act) and Section 508 require organizations to support TTY for individuals if readily achievable. ipTTY, provided the PBX/VoIP system supports SIP, makes this requirement readily achievable. ipTTY also supports RFC 4103 or what some commonly refer to as Text over IP Text over IP (or ToIP) is a means of providing a real-time text (RTT) service that operates over IP-based networks.

Timed Text
Timed text is the presentation of text media in synchrony with other media, such as audio and video. Applications Typical applications of timed text are the real-time subtitling of foreign-language movies on the Web, captioning for people lacking audio devices or having hearing impairments, karaoke, scrolling news items or teleprompter applications. Timed text for MPEG-4 movies and cellphone media is specified in MPEG-4 Part 17 Timed Text, and its MIME type is specified by RFC 3839. Markup language specifications The W3C keeps two standards intended to regulate timed text on the Internet: the Timed Text Markup Language (TTML) and WebVTT (currently in draft stage). SMPTE created additional metadata structures for use in TTML and developed a profile of TTML called SMPTE-TT. The DECE incorporated the SMPTE Timed Text in their UltraViolet Common File Format specification. Competing formats Interoperability for timed text came up during the development of the SMIL 2.0 specif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Public-safety Answering Point
A public-safety answering point (PSAP), sometimes called public-safety access point, is a call center where emergency/non-emergency calls (like police, fire brigade, ambulance) initiated by any mobile or landline subscriber are terminated. It can also happen that when 112 is dialed in then a logic is implemented by mobile or network operators to route the call to the nearest police station. It is a call center in almost all the countries including Canada and the United States responsible for answering calls to an emergency telephone number for police, firefighting, and ambulance services. Trained telephone operators are also usually responsible for dispatching these emergency services. Most PSAPs are now capable of caller location for landline calls, and many can handle mobile phone locations as well (sometimes referred to as phase II location), where the mobile phone company has a handset to location system. Some can also use voice broadcasting where outgoing voice mail can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
