Model Description:
HD/SD Video Delay / Time Shift Processor

Model Details

In live shows, there is invariably the need to time-shift various feeds that contribute to the final production. This may be required to provide delays to accomplish profanity censorship, contribution backhaul delay mis-match compensation or compliance for other contractual obligations.

The Evertz HDSD9545DLY-PRO Time shifting delay processor has been designed to give an operator complete control over the program content being broadcast to air. This product enables the operator to insert the desired time delay via a front panel control and display panel. There are two program paths which are HD and SD compatible.

The main program feed will usually be focused on the main detailed action. Both channels are delayed by the same amount. If an unscheduled switch to an alternate source is required, the operator has only to hit one remote button to cause the program video and audio output to be clean switched to the alternative back-up channel. The output can be returned to the main program content without interruption to the video, or pops and clicks in the audio.

The delay can be adjusted from a minimum 2 frame program or to a maximum of 40 seconds of 1.5Gb/s HDTV or 240 seconds for SDTV (with the HD40 option). This max delay can be allocated to primary and secondary paths as per the user.
