The Videotek® VSG-4TCG time code generator inputs time information from various sources, including Linear Time Code (LTC), Vertical Interval Time Code (VITC), Digital Vertical Interval Time Code (DVITC), Ancillary Time Code (ATC), Global Positioning Systems (GPS), IEEE-1588 Precision Time Protocol (PTP), Network Time Protocol (NTP) servers, and local time (internal Generator). The module's internal timing engine processes the incoming reference information, makes appropriate conversions to a different time code format, and maintains a consistent time code which is used to drive the module's outputs.
Using a combination of parameters such as DST rules and offset values, the VSG-4TCG can be configured to convert incoming International Atomic Time (TAI) to other time code formats. This time is then distributed to the SDI and LTC outputs as time and date information.
Time code generators and readers are used in Production, Post production and Telecine transfer operations. Every studio or OB van, every post production facility and every telecine installation needs a time code generator to ensure proper operation.
If GPS lock time and date are required, the optional GPS-3903-2 with serial data time and date outputs is recommended.
