2 DSK-3901 3G/HD/SD Downstream Keyer
2.1 Introduction
The Densité DSK-3901 is a low cost, single card downstream keyer, with two independent pairs of fill and key inputs.
This 3G/HD/SD keyer is ideal for inserting two external character generator feeds over program video. Up to 10
channels of keying can be housed in a single 3RU Densité frame.
A dedicated full preview channel offers an operator the option to feed the same signal to the program and preview
chains, or use a different signal for the preview chain using the Fill-2 input.
The DSK-3901 can be manually controlled by the Branding Panel, and under automation using the widely adopted
Oxtel protocol.
The DSK-3901 allows further upgrades and purchasable options which provide additional features such as AB mixing,
audio mixing and audio voice-overs.
The integrated audio engine provides multi-channel AB mixing and voice-overs. Audio is accepted as embedded
audio or by four external AES inputs, and background audio is automatically ducked during voice-overs.
The DSK-3901 card lacks support for the internal stores that are found on LGK-3901. Consequently it has no store-
related features such as still images, animations, clocks and Easytext. Nor does it have support for audio clip playout
via the Easyplay feature. Upgrade options may however be purchased to convert a DSK-3901 card into an LGK-3901
(see section 9.2).
