SMPTE timecode ( / ˈsɪmptiː / or / ˈsɪmtiː /) is a set of cooperating standards to label individual frames of video or film with a timecode. The system is defined by the Society of Motion Picture and Television Engineers in the SMPTE 12M specification. SMPTE revised the standard in 2008, turning it into a two-part document: SMPTE 12M-1 ...
Linear (or Longitudinal) Timecode ( LTC) is an encoding of SMPTE timecode data in an audio signal, as defined in SMPTE 12M specification. The audio signal is commonly recorded on a VTR track or other storage media. The bits are encoded using the biphase mark code (also known as FM ): a 0 bit has a single transition at the start of the bit period.
Timecode. A timecode (alternatively, time code) is a sequence of numeric codes generated at regular intervals by a timing synchronization system. Timecode is used in video production, show control and other applications which require temporal coordination or logging of recording or actions.
SMPTE ECR 1-1978 (SDTV) In a SMPTE color bar image, the top two-thirds of the television picture contain seven vertical bars of 75% intensity. In order from left to right, the colors are white or gray, yellow, cyan, green, magenta, red, and blue. [18] The choice of white or gray depends on whether that bar's luminance is 100% or not.
Vertical Interval Timecode ( VITC, pronounced "vitsee") is a form of SMPTE timecode encoded on one scan line in a video signal. These lines are typically inserted into the vertical blanking interval of the video signal. With one exception, VITC contains the same payload as SMPTE linear timecode (LTC), embedded in a new frame structure with ...
Control track longitudinal timecode. Control track longitudinal timecode, or CTL timecode, developed by JVC in the early 1990s, is a unique technique for embedding, or striping, reference SMPTE timecode onto a videotape. Similar to the way VITC timecode is embedded in the vertical interval area of a video signal, CTL timecode embeds SMPTE ...
Time code format. The MIDI time code is 32 bits long, of which 24 are used, while 8 bits are unused and always zero. Because the full-time code messages requires that the most significant bits of each byte are zero (valid MIDI data bytes), there are really only 28 available bits and 4 spare bits. Like most audiovisual timecodes such as SMPTE ...
SMPTE 2110 is a suite of standards from the Society of Motion Picture and Television Engineers (SMPTE) that describes how to send digital media over an IP network. [1] SMPTE 2110 is intended to be used within broadcast production and distribution facilities where quality and flexibility are more important than bandwidth efficiency.
