Abstract: A camera support comprises a baseplate on which first and second engaging means are formed for releasably engaging first and second portions of a camera body displaced along the baseplate in an engaging direction. The first engaging means defines an abutment position for the first portion of the camera body, and the second engaging means defines a space between two sidewalls for slidably receiving a web of second portion of the camera body, and wherein one of said sidewalls is displaceable towards the other and is coupled to a trigger of the first engaging means so as to clamp the web between the sidewalls when the trigger is operated by the first portion reaching the abutment position. A camera support of this kind can be used advantageously for a respective camera assembly, for example a superexpander.

Abstract: In high-end professional video cameras a triax system is used for transferring various signals back and forth over a single coaxial cable between the camera and a base unit using frequency multiplexing. In low-cost camera systems the analogue camera CVBS video output signal is replaced by a standard serial SDI signal from the camera to a base unit, having a maximum data rate of e.g. 270 Mbit/s for standard definition TV signals. According to the invention, the camera/base unit system is locked via SDI channels whereby the base unit video output is synchronised to the base unit Genlock signal. The camera unit and the base unit each use a local oscillator and H and V counters, whereby in the camera unit only a frequency locking is carried out.
