The HD-DSK is a High Defintion downstream linear keyer. Each card accepts Fill, Key, Background and Preview inputs and provides two Programme and one Preview output. The HD-DSK is part of a new family of low-cost modular HD products that all fit into the same format 1-U rack-frame system. The HD-RK4 rack has relay bypass in case of mains failure, making them suitable for on-air and broadcast use. HD-DSK can be used in systems with EasyMix-HD mixers and HD-LOGO logo generator/inserters with up to 4 cards housed in a single 1-U rackframe.
The HD-DSK operates with all current HD and SD standards and provides linear keyer images with cut and fade transitions.
Applications:
- On-Air keying
- Post-production
- A/V Systems
- Corporate Presentations
