FOR-A : UFM-80TSCS
TS changeover switcher
Video and Audio Systems for Broadcast Post-Production, and Professional Video
Description
The For-A UFM-80TSCS TS Changeover Switcher is a modular-type unit featuring 2 inputs, which can be mounted in a UFM frame. This TS automatic seamless switcher constantly monitors 2 TS signals output from the same encoder on a redundant circuit for errors, and switches the output seamlessly to the other line when an error occurs. To prevent an error on the transmission path, this switcher further increases the reliability of duplex transmission.
Downsizing can be achieved by equipping multiple modules to a single UFM frame. Up to 5 modules can be equipped to the UF-106B (sold separately), and up to 9 modules (sold separately) to the UF-112. In addition, different module types can also be simultaneously equipped.
Features
UFM-80TSCS features include:
- Seamless switching can be performed between the dual output distributions of the same encoder using a single module. This supports completely seamless switching without disrupting the video or audio (single TS module configuration).
- When an error occurs in the signal, this unit automatically switches to the other line. Manual switching and auto/manual assignment of each line are also possible. For example, the following assignment can be selected: automatic switching from the current line to the reserve line, and manual switching from the reserve line to the current line.
- The delay difference between different lines is absorbed quickly and both phase inputs are automatically aligned to achieve seamless switching that does not disrupt the output. The delay adjustment range is ±500 ms.
- This unit monitors the error content occurring in the transmission path, and performs error detection with an emphasis on achieving seamless switching. This helps protect transmission signals from SYNC errors, CC errors, packet loss, NULL only, and other errors that can fatally damage signal quality. Detection of each error type can be set to On or Off. The PID error detection threshold can be set to an arbitrary time (1 msec steps). Up to 4 sets of multi-program signals are supported.
- When the power is Off, the bypass-through function operates so that the input1 input signal is output to output1.
- Each module is equipped with a GPI interface (7-pin, 36 items) and Ethernet, enabling a wide range of remote monitoring and control according to the operation format. The dedicated GUI can be used to make settings and graphically display error-monitoring contents via Ethernet. An event log viewer, automatic CSV file generation, and other functions are also provided to facilitate signal management requiring historical condition data.
