XRC-3901

NEO Modular Frame Rate Converter

THIS PRODUCT HAS BEEN DISCONTINUED AND AVAILABILITY IS BASED ON EXISTING INVENTORY.

PLEASE CONTACT YOUR HARRIS SALES REPRESENTATIVE FOR AVAILABILITY.

Ideal for broadcast frame rate conversion, the NEO® XRC-3901 is a modular conversion product for the NEO advanced applications mounting frame.

Applications that use frame rate conversion include incoming satellite signals from countries with a different frame rate standard for ingest of programs such as drama, news and weather. For live events such as music festivals or sports events, the XRC-3901 is ideal for non-critical feeds or as a backup to a motion compensated frame rate converter. In production, the XRC-3901 frame rate conversion is used in the duplication facility to provide “dupes” of differing frame rates.

Embedded audio (up to 16 channels) and discrete AES (up to 8 AES) are delayed automatically to maintain lip synchronization.

When frame synchronization is required, it is recommended that the signal to be converted be fed into the XRC-3901 module, and then the output of the XRC-3901 be fed to an existing or optional frame sync that is locked to house reference. In the event that the input signal is marginal or lost, the XRC-3901 will pass the marginal signal, and the existing or optional frame sync will provide a clean output into the ingest sub-system.
