Horita PTG
Portable Time Code Generator


The PTG is the latest addition to Horita's line of miniature handheld portables for use in the field.  This palm- sized generator is simple to setup and operate and features a large 2-line liquid crystal display (LCD) readout for time code, user bits, and setup information.  The PTG is an ideal generator for use with inexpensive camcorders in multi camera situations where it is necessary for each tape to have the same time code for precise time and image matching during post production.  These situations may include sporting events, games, concerts, automobile, aircraft, and boating events, parades, weddings, etc.

For these applications the PTGs are jammed (automatically preset) to the same time code source and the user bits of the time code are set to the date and also include a unique ID number for each individual PTG.  Each tape recorded in this manner will have the same time and date but a different ID number so they can't get mixed up later.  The PTG can also jam to an RS232 serial data input from a GPS receiver for generation of precise time of day and date time code.

Horita PTG Features:

  • Reads and generates SMPTE time code at six frame rates of  23.976FPS, 24FPS, 25FPS, 29.97FPS DF (Drop Frame), 29.97FPS NDF (Non-Drop Frame), and 30FPS (FPS= frames-per-second)
  • Provides selection of "LINE" or "MIC" output level when generating timecode and includes various common MIC/ LINE adapter connectors.*

*The PTG upgrade for MIC/ LINE output level selection consists of hardware and software modifications to the PTG unit itself, plus also includes an 18" RCA-to-RCA cable and XLR, mini- phone, and BNC adapters for inputting time code into your equipment. The PTG must be returned to the factory and the total cost is $50 plus return shipping. Please contact Horita or your sales representative for further details.

  • Time code generator "auto jam" mode presets the generator to TC or GPS serial data input values for time and date. Once jammed, generator operation continues and can be stopped only by powering the PTG off. This prevents accidentally stopping the generator via unintended actuation of the "run/ stop" switch.
  • The low "free run" drift rate of of a maximum of one frame per hour over temperature provides close matching of the PTG time with that of the jam source throughout the day. Actual drift rate is much better than one frame per hour if the PTG is not subjected to large temperature changes, such as from being left in the sun or out in freezing conditions.
  • Time code reader mode displays time code, user bits, and frame rate values when reading time code, or GPS time and date values when reading GPS data.
  • Powered over 24 hours on a single 9V battery.
  • All settings and presets are maintained in non-volatile memory, even whenthe battery is removed
