Do you have a request to accurately measure the transmission delay of imaging equipment? The delay measurement unit DPN2011B can meet such a request.
The Delay Measurement Unit (DPN2011B) is a unique product that can measure the total video delay time of a system composed of an imaging camera, video transmission system, and display monitor. The LED lamp that flashes on and off with the trigger signal generated from DPN2011B is displayed on the monitor via the camera and video transmission system. The ON/OFF state of the LED flashing image on the monitor is captured by a photodiode (PD) and converted into an electrical signal. The difference between this signal and the trigger signal, which represents the total video delay time, is automatically acquired using a PC-connected oscilloscope and dedicated software "AccuLatencyII," allowing for data recording of the entire system's delay time on a PC. Additionally, as an option for measuring video delay between two distant points, we have prepared a GPS module (DPN2015B) and a timing keeper (DPN2016A). The DPN2015B can receive the 1-second periodic pulse signal from GPS satellites at each remote location, serving as a reference for delay time measurement. It should be noted that GPS pulse signals can be difficult to receive depending on the satellite's position or if indoors, and the timing keeper DPN2016A is the device that can capture pulses while DPN2015B is receiving GPS pulses.

■GPS Module (DPN2015B): This unit is used to measure video delay between two distant points with the DPN2011B. The DPN2015B receives a 1-second periodic pulse signal from GPS satellites and can generate pulse signals with precise timing synchronization at intervals of 1, 5, 10, and 20 seconds anywhere. By preparing two sets of DPN2015B, one can flash an LED lamp at the location where the camera is placed using the pulse signal from DPN2015B, while the other is connected to the DPN2011B unit at the location where the LED lamp image is flashing on the monitor via the video transmission system. By using the GPS pulse signal as the trigger signal for the DPN2011B, it becomes possible to measure video delay between the two distant locations. ■Timing Keeper (DPN2016A): When using the DPN2015B, it is necessary to receive pulse signals from GPS satellites during measurement. However, GPS pulse signals can be difficult to receive depending on the satellite's position or in indoor environments. Therefore, the Timing Keeper DPN2016A is a unit that can capture pulses while the DPN2015B is receiving GPS pulse signals. The DPN2016A is equipped with an OCXO and can maintain accurate timing for extended periods with battery power.

Company information
Koh Pass Communications Inc. is a venture established by volunteers from the National Institute of Advanced Industrial Science and Technology (AIST). Utilizing the new optical communication technology called Dynamic Optical Path Network (DOPN), developed through the VICTORIES project at AIST, we are advancing the commercialization of this new optical communication technology and its derived technologies, which enable the bidirectional, zero-delay transmission of uncompressed optical signals between distant locations with ultra-low power consumption. "TeleSession" leverages DOPN as a platform to transmit 4K/8K ultra-high-definition video and high-quality audio in an uncompressed, zero-delay manner, allowing for real-time sharing as if through a "connecting window," aiming for applications in telemedicine and spatial sharing in distant music and theater halls. Additionally, the dark fiber network for DOPN can be used as a transmission path for high-capacity Ethernet. Our company focuses on three main pillars of business: building optical fiber network platforms, manufacturing and selling uncompressed optical transmission equipment for TeleSession, and producing and selling delay measurement units that can accurately measure the delay in video transmission.
