1.1.7 Advanced TriaxHD features
TriaxHD, which is a further development of the Emmy Award winning triax transmission
system, makes the camera compatible with industry standard triax cables. This allows the
reuse of existing, reliable and valuable cable inventories.
TriaxHD allows video transmission and remote control of cameras up to a distance of 3300 ft
(1000 meters) and beyond, using industry standard 14mm triax cables. It is based on 30MHz
full-bandwidth 4:2:2 transmission (Y/Cr/Cb components).
The double side band modulation technique used in combination with Y/Cr/Cb transmission
ensures linearity, resolution and an optimal signal-to-noise ratio over the maximum cable
length. Bandwidth efficient channel combining and equalization techniques minimize cross-
talk and interference. Teleprompter and viewfinder signals maintain high performance with
relatively long cable lengths.
The communication facilities provide for two-wire or four-wire high quality intercom signals.
Full camera control is provided via a C2IP Ethernet-based control network.
The TriaxHD adapter is equipped with a rotary triax connector which provides freedom of
movement during portable use of the camera and protects the connector from being
damaged in near-floor conditions.
TriaxHD Base Station
The TriaxHD Base Station, as well as providing high definition outputs, optionally offers
simultaneous high-end SDTV outputs. This facilitates a gradual and managed transition from
SDTV to HDTV.
1.1.8 SuperXPander
The Triax SuperXpander large lens adapter together with the optional 7-inch HD high
resolution viewfinder turns the portable triax camera into a full-featured studio camera for
studio and EFP situations.
