7743DLY-HD
HD/SD-SDI Video Delay
The 7743DLY-HD is a full function HD/SD-SDI Video Delay module designed for applications such as: satellite uplink, signal re-entry on master control inputs, at cable headends, mobile vehicle outputs, broadcast transmitter inputs, virtual sets and matching delays caused by multi-channel audio compression.
The 7743DLY-HD can act as a delay for SD video (SMPTE 259M) or HD video (SMPTE 292M).
The 7743DLY-HD is capable of up to 3.2 seconds of delay for HD and up to 16.5 seconds of delay for SD. With the broadcast environment in mind, the modules feature bypass relay protection on output.
The 7743DLY-HD occupies two card slots and can be housed in the 1RU 7701FR frame which holds up to three single or dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
