KayakDD - Digital Production Switcher
2.6 Signal Routing
2.6.1 Inputs and Sources
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.
For example, a character generator usually provides a signal with two components
(commonly called
video and key ). Some incoming signals may also originate from
devices the KayakDD system can control (Router, DPM, DDR).
For a KayakDD Digital Production Switcher, the term source refers to all the video
signals and other attributes associated with a device. This is a fundamental concept.
The KayakDD 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 KayakDD system uses ID numbers, not source names or input
connectors, to identify each source. Defining each source is an important aspect of the
KayakDD system.
2.6.2 Source Definition
The source definition process includes assigning a name to each source. Once
sources are defined, the user is able to select the source by name. Sources having
separate video and key signal are coupled in the key couple menu to allow a single
button selection for appropriate keying. Tally relays are assigned to the according
inputs in the GPO menu.
All these settings are part of a configuration and can change from production to
production.
2.6.3 Button Assignment (Source to Button Mapping)
Source to button mapping makes it possible to organize sources on KayakDD control
panels in a preferred order. For example, cameras can be placed on the left side or the
right side of the button row, whichever is preferred.
Source mapping is distinct from source definition, as source mapping only involves the
location of sources on the control panel and does not affect any capabilities defined for
the sources. Note that E-MEM effects store the source IDs, not the source select
buttons, so remapping sources will not change the appearance of recalled effects.
Button assignment is possible via the Sidepanel program.
