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.

2011年4月15日 · vitc 场消隐期时间码是 sony等公司研制并推广使用的，这种时码将时间码信号插在场消隐期，用视频磁头与视频信号同时记录。 其特点是： （1） 读码准确可靠，不受带速影响。

In television broadcasting, VIT signals (vertical interval test signals) are a group of test signals inserted in the composite video signal.

2024年3月3日 · There is currently Unai VITC which allows you to create video streams with VITC timecode for embedding into files. And hardware generators are still available on sites like eBay which can use VITC/LTC cross-translation.

Time code in the vertical interval, this is a time code recorded on a series of dedicated lines on the video track that are recorded in the vertical erase interval. It can be read perfectly even during slow speed playback or in still images.

一般是将两种信号同时记录在带上，当 录像带运行速度降至某一门限速度之下时，时码读出器自动选择 vitc 码读出；当带速高出 某一门限时，则改换到 ltc 码的读出。

Unai.VITC is a simple VITC (vertical interval timecode) signal generator, written in C# for .NET 6.0. Unai.VITC is a console application: you must use it through a terminal and control how it works by passing arguments to it (like changing the framerate; see below).

Current HD-SDI streams support only two timecode formats: ATC_VITC and ATC_LTC. These are both packet-based, and are located on unique lines in the ancillary space and can typically be assigned to any line within a range of line 9 to line 20.

2008年2月7日 · This standard defines a transmission format for conveyance of linear (LTC) or vertical interval (VITC) time code data formatted according to SMPTE 12M-1 in 8-, 10-, or 12-bit digital television data interfaces.

An internal DIP switch provides selection of the VITC video line, or Automatic Line Identification (First Good). A +/-1 Frame switch is provided to compensate for different types of LTC displays.
