For example, a character generator usually provides a signal with two com-
ponents (commonly called video and key). Some incoming signals may also
originate from devices the Kayak HD system can control (Router, DPM,
DDR).
For a Kayak HD Digital Production Switcher, the term source refers to all the
video signals and other attributes associated with a device. This is a funda-
mental concept. The Kayak HD system is based on sources, not input
signals or crosspoints. Each source can be given a descriptive name, but has
an ID Number for absolute identification. The Kayak HD system uses ID
numbers, not source names or input connectors, to identify each source.
Defining each source is an important aspect of the Kayak HD system.
Kayak DD
Incoming video signals are connected to the KayakDD system via BNC
connectors on the rear of the KayakDD Digital Processor frame. All inputs
are serial digital (SMPTE 259M, CCIR 601). Signals from external devices
not operating in this standard will need to be converted.
Some devices (for example, a camera providing serial digital output) may
provide a video signal that can be received on a single connector. However,
other devices may output multiple signals.

Source Definition
The source definition process includes assigning a name to each input
source. Once sources are defined, you can then select the source by name in
the control panel menu. Sources that use separate video and key signals are
coupled in the Input menu to allow a single button to select the video-key
pair from the switcher control panel. Tally relays can be assigned to the cor-
responding inputs in the
Config - GPO/Tally menu. All these settings are part
of a configuration and may change from production to production.
