3GPP Timed Text
MPEG-4 Part 17, or MPEG-4 Timed Text (MP4TT), or MPEG-4 Streaming text format is the text-based subtitle format for MPEG-4, published as ISO/IEC 14496-17 in 2006. It was developed in response to the need for a generic method for coding of text as one of the multimedia components within audiovisual presentations. It is also streamable, which was one of the main aspects when creating the format. It is mainly aimed for use in the .mp4 container, but can also be used in the .3gp container as 3GPP Timed Text (TTXT), which is technically almost identical with .mp4 but more used in cell phones. 3GPP Timed Text is exactly the same as MPEG-4 Timed Text when used in the .mp4 container. It can be also used in other file formats based on the ISO base media file format. 3GPP approved the Timed text format for 3G multimedia services in 3GPP TS 26.245 in 2004. MPEG-4 Part 17 (ISO/IEC 14496-17:2006) defined ''Text Streams'' that are capable of carrying 3GPP Timed Text. For 3GPP text streams, IS ...

Subtitle (captioning)
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. Someti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fourcc
A FourCC ("four-character code") is a sequence of four bytes (typically ASCII) used to uniquely identify data formats. It originated from the OSType or ResType metadata system used in classic Mac OS and was adopted for the Amiga/Electronic Arts Interchange File Format and derivatives. The idea was later reused to identify compressed data types in QuickTime and DirectShow. History In 1984, the earliest version of a Macintosh OS, Apple System 1, was released. It used the single-level Macintosh File System with metadata fields including file types, creator (application) information, and forks to store additional resources. All these fields are four-character codes known as OSType. It was possible to change this information without changing the data itself, so that they could be interpreted differently. Identical codes were used throughout the system, as type tags for all kinds of data. In 1985, Electronic Arts introduced the Interchange File Format (IFF) meta-format (family of ...

Markup Languages
Markup language refers to a text-encoding system consisting of a set of symbols inserted in a text document to control its structure, formatting, or the relationship between its parts. Markup is often used to control the display of the document or to enrich its content to facilitating automated processing. A markup language is a set of rules governing what markup information may be included in a document and how it is combined with the content of the document in a way to facilitate use by humans and computer programs. The idea and terminology evolved from the "marking up" of paper manuscripts (i.e., the revision instructions by editors), which is traditionally written with a red pen or blue pencil on authors' manuscripts. Older markup languages, which typically focus on typography and presentation, include troff, TeX, and LaTeX. Scribe and most modern markup languages, for example XML, identify document components (for example headings, paragraphs, and tables), with the ...

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.

Ogg Writ
Ogg is a free, open container format maintained by the Xiph.Org Foundation. The authors of the Ogg format state that it is unrestricted by software patents and is designed to provide for efficient streaming and manipulation of high-quality digital multimedia. Its name is derived from "ogging", jargon from the computer game ''Netrek''. The Ogg container format can multiplex a number of independent streams for audio, video, text (such as subtitles), and metadata. In the Ogg multimedia framework, Theora provides a lossy video layer. The audio layer is most commonly provided by the music-oriented Vorbis format or its successor Opus. Lossless audio compression formats include FLAC, and OggPCM. Before 2007, the .ogg filename extension was used for all files whose content used the Ogg container format. Since 2007, the Xiph.Org Foundation recommends that .ogg only be used for Ogg Vorbis audio files. The Xiph.Org Foundation decided to create a new set of file extensions and ...

VLC Media Player
VLC media player (previously the VideoLAN Client and commonly known as simply VLC) is a free and open-source, portable, cross-platform media player software and streaming media server developed by the VideoLAN project. VLC is available for desktop operating systems and mobile platforms, such as Android, iOS and iPadOS. VLC is also available on digital distribution platforms such as Apple's App Store, Google Play, and Microsoft Store. VLC supports many audio and video compression methods and file formats, including DVD-Video, Video CD and streaming protocols. It is able to stream media over computer networks and can transcode multimedia files. The default distribution of VLC includes many free decoding and encoding libraries, avoiding the need for finding/calibrating proprietary plugins. The libavcodec library from the FFmpeg project provides many of VLC's codecs, but the player mainly uses its own muxers and demuxers. It also has its own protocol implementations. It also ...

VideoLAN
VideoLAN is a non-profit organization which develops software for playing video and other media formats. It originally developed two programs for media streaming, VideoLAN Client (VLC) and VideoLAN Server (VLS), but most of the features of VLS have been incorporated into VLC, with the result renamed VLC media player. The VideoLAN project began as a student endeavor at École Centrale Paris (France), but after releasing the software under the free software/open source GNU General Public License, the project is now multinational with a development team spanning 40 nations. The project has been completely separated from École Centrale Paris since 2009 when it was constituted as a non-profit organization. The current President of the VideoLAN non-profit organization is Jean-Baptiste Kempf, who is also one of the project's developers.
