Model Description:
Imagine Communication, Videotek, 3G/HD/SD Master Timing Generator/Clock system driver

Model Details

The Videotek® VSG-4MTG is part of the Imagine Communications Reference Sync and Timing platform, and is a ½RU wide, 1RU tall and 12 inches deep 3G/HD/SD master timing generator. The unit is small in size, with redundant power supply inputs, and is low in power consumption and light in weight, making it a perfect fit for all broadcast television and post production environments.

The VSG-4MTG/VSG-4CSD master timing generators input time information from various sources, including Linear Time Code (LTC), Vertical Interval Time Code (VITC), Global Positioning Systems (GPS), and Network Time Protocol (NTP) servers. The module's internal timing engine processes the incoming reference information, makes appropriate conversions to different time bases, and maintains a consistent time base which is used to drive the module's outputs.

Using a combination of parameters such as leap second information, DST rules, and offset values, the VSG-4MTG/VSG-4CSD can be configured to convert incoming International Atomic Time (TAI) to other time bases. This time is then distributed to the module's outputs as time and date information, and black burst video reference signals.
