FRS-HD-CHO – DISCONTINUED (LTB 02.06.2021) 2x1 HD-SDI Change-over with frame synchronizer

Order no: (18088) - DISCONTINUED

The Flashlink FRS-HD-CHO is a feature rich 2×1 HD/SD-SDI change-over module with built in framesynchronizer providing error-free switching between two sources. The FRS-HD-CHO is ideal for use with SNG vans where it is mission critical to provide an uninterrupted signal feed to downstream equipment like MPEG-2encoders. Its space saving design and best-inclass low power consumption adds to an impressive feature set. FRS-HD-CHO can be added to any field-deployed unit and is ideal for on-air applications. The HD/SD framesync solution provides a feature for de-glitching of the input source, providing seamless, error-free synchronous switching between two sources.

The FRS-HD-CHO also supports ASI swithcing and is capable of doing in-depth monitoring of ASI stream according to ETR.290 1.1 and 1.2. In addition the module features passive relayed bypass of its two inputs to secure signal chain at power down.
