Chapter 1 - Introduction
1.1.7 WorldCam version
The WorldCam version provides, in addition to the Standard version formats, digital
cinematography formats in 1080p and 720p, which give an impression of motion comparable
to film cameras running at identical speeds.
The WorldCam also provides convenient built-in frame-rate conversions for easy connection
to existing HD peripherals, offering possibilities for cost-effective monitoring and recording
combined with the motion portrayal of film cameras. The 1080p format at 23.98 Hz, for
example, can be converted using 3:2 pull-down to 1080i at 59.94 Hz right inside the camera.
The following acquisition formats are available for the WorldCam version:
– 1080i at 59.94 Hz
– 1080i at 50 Hz
– 1080p at 23.98 Hz
– 1080p at 24 Hz
– 1080p at 25 Hz
– 1080p at 29.97 Hz
– 720p at 59.94 Hz
– 720p at 50 Hz
– 720p at 23.98 Hz
– 720p at 25 Hz
– 720p at 29.97 Hz
1.1.8 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 1,200 m
(4,000 ft.) and beyond, using industry standard 14 mm 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.
