Horita GPS-MTG2 overview

  • 1Description

The HORITA GPS-MTG2 is a GPS based Master SMPTE timecode generator intended to provide time and date format timecode for operating various types of SMPTE timecode based equipment, such as analog, digital, and video overlay time-of-day clock displays, date displays, and automation and playback systems. It also finds application in various field, studio, editing, engineering, and post production situations.

The MTG2 generates industry standard longitudinal (also called linear) format SMPTE timecode (LTC) at various user selectable frame rates and provides both balanced and un-balanced output signals. In addition to the GPS system, the MTG2 can set and maintain the generated timecode to the time and date from an internal RTC (Real Time Clock) chip or to an externally applied SMPTE timecode input.

The MTG2 provides user selection of local time zone offsets from UTC time and also provides automatic Daylight Savings Time (DST) time and date correction if desired. As the MTG2 generates the timecode, the original reference signal used to preset the generator is monitored and its time value is compared to that of the MTG2 timecode being output. If there is a time error difference that exceeds a user preset value, the MTG2 then automatically presets it's time to the source time.

If the original preset signal fails to occur for longer than about five minutes, the MTG2 will output an Alarm signal and then either switch over to the pre-selected backup source for the time and date, or continue to free run locked to the precision internal crystal frequency which will maintain the time accurate to within ±1 frame per hour.
