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

1.1.8Advanced 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.
