DK-Technologies To Showcase Global Positioning System At NAB

DK-Technologies will be attending NAB 2007 (Booth N1835) with a new global positioning system (GPS) genlock option for its PT5300 Sync and Test Signal Generator systems.
The GPS option (PT8616) will enable ultimate timing stability of the generators by locking against the GPS time reference. When GPS genlock is used, the timing of the output signals from the PT5300 will be well defined relative to the real-time clock – e.g. the start of a video frame will be well defined in absolute time. This enables a number of independent PT5300's to be running in sync even though they are physically separated by a long distance and have no direct interconnection for synchronization.
The PT8616 option will also ensure that the frequency reference is always correct in a master generator setup. When redundant systems are used with changeover units (PT5211), the individual master generators can be synchronized via the PT8616 option, causing minimum disturbance if a changeover situation should occur.
By using PT5300's with PT8616 options, remote facilities can be synchronized to the master complex and signals can be transferred without the risk of having artifacts induced by frame synchronizers or frame buffers skipping or repeating frames due to unsynchronized sync domains.
In addition to precisely controlling the timing of video and audio signals, the PT8616 option enables retrieving of ultra precise real time clock data from the GPS. Timecode, containing the real time clock information can be sourced directly from the PT5300 and used as master clock in the complex.
The PT8616 option consists of a hardware module that integrates seamlessly into the PT5300 generator. A robust weatherproof antenna, cable and mounting accessories are also included.
