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 ...

Subtitles
Subtitles and captions are lines of dialogue or other text displayed at the bottom of the screen in films, television programs, video games or other visual media. They can be transcriptions of the screenplay, translations of it, or information to help viewers who are deaf or hard-of-hearing understand what is shown. Subtitles refer to a text translation of audio into a different language and are for people who can hear the audio, but may not be able to understand the dialogue. Captions are text in the language of the audio and are designed for anyone unable to hear the audio, they often also contain important sounds that would be unavailable for anyone unable to hear the audio. Open captions are "burnt" into the video and will therefore always be visible, while closed captions (CC) can be toggled on and off according to the preference of the viewer. Methods Subtitles can be rendered as part of the video or separately as graphics or text overlaid on the video. Sometimes, ...

UltraViolet (System)
UltraViolet was a cloud-based digital rights locker for films and television programs that allowed consumers to store proofs-of-purchase of licensed content in an account to enable playback on different devices using multiple applications from several different streaming services. UltraViolet also allowed users to share access to their library with up to five additional people. UltraViolet was deployed by the Digital Entertainment Content Ecosystem (DECE), an alliance of 85 companies that includes film studios, retailers, consumer electronics manufacturers, cable television companies, internet service providers (ISPs), internet hosting vendors, and other internet systems and security vendors, with the notable exceptions of Walt Disney Studios, Google, Amazon and Apple. On January 31, 2019, DECE announced that Ultraviolet would shut down on July 31, 2019. This shutdown came after the launch of Movies Anywhere over a year earlier, along with Fox, Universal, Lionsgate, Paramou ...

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. 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 i ...

SubRip
SubRip is a free software program for Microsoft Windows which extracts subtitles and their timings from various video formats to a text file. It is released under the GNU GPL. Its subtitle format's file extension is .srt and is widely supported. Each .srt file is a human-readable file format where the subtitles are stored sequentially along with the timing information. Most subtitles distributed on the Internet are in this format. SubRip software Using optical character recognition, SubRip can extract from live video, video files and DVDs, then record the extracted subtitles and timings as a ''Subrip format'' text file. It can optionally save the recognized subtitles as bitmaps for later subtraction (erasure) from the source video. In practice, SubRip is configured with the correct codec for the video source, then trained by the user on the specific text area, fonts, styles, colors and video processing requirementsZuggy, Guide. to recognize subtitles.

Synchronized Multimedia Integration Language
Synchronized Multimedia Integration Language (SMIL ()) is a World Wide Web Consortium recommended Extensible Markup Language (XML) markup language to describe multimedia presentations. It defines markup for timing, layout, animations, visual transitions, and media embedding, among other things. SMIL allows presenting media items such as text, images, video, audio, links to other SMIL presentations, and files from multiple web servers. SMIL markup is written in XML, and has similarities to HTML. Version history , the W3C Recommendation for SMIL is ''SMIL 3.0''. SMIL 1.0 SMIL 1.0 became a W3C Recommendation on 15 June 1998. SMIL 2.0 ''SMIL 2.0'' became a W3C Recommendation on 9 August 2001. SMIL 2.0 introduced a modular language structure that facilitated integration of SMIL semantics into other XML-based languages. Basic animation and timing modules were integrated into Scalable Vector Graphics ( SVG) and the SMIL modules formed a basis for Timed-Text. The modular struc ...
