7780DLY-ASI

ASI Delay

VistaLINK® 兼容

The 7780DLY-ASI is a complete hardware based solution that can delay a compressed stream on ASI for up to 16 seconds. As more providers are using different sources with various delays, like satellite, fiber and off air, they need to be able to match these streams by delaying them by multiple seconds in order to line up in time the different inputs.

Most broadcast equipment offers few millisecond of built in buffer, but in many cases it is not enough delay for stream matching.

The 7780DLY-ASI can delay a full ASI stream up to 213Mb/s. The delay is programmable and adjustable by 1ms increment from 0 to 16 seconds.

The 7780DLY-ASI fits in the 7700 series frame and offers signal input monitoring by sending SNMP traps to the industry leading VistaLINK® PRO.

特点
