A broadcast camera is provided that includes a camera housing having connectable camera housing portions to define a front, middle and rear sections of a camera body. An electronic component is provided in the front section of the camera housing and a power transformer is mounted in the rear section of the camera housing. A duct housing is mounted within the camera housing to form a cooling duct that extends through the camera housing, with a front duct housing that is positioned adjacent to the electronic component and that separates the electronic component from the cooling duct. Moreover, heat sinks extend within the cooling duct in one of the upper, middle and lower front duct sections and are mounted to be in thermal communication with the at least one electronic component. A fan is mounted within the cooling duct to draw air into the cooling duct.

A rotatable disc comprises a first zone in which a plurality of features, e.g. optical filters, are located at uniform angles from each other with respect to an axis of rotation of the disc and a second annular zone comprising sets of adjacent marks of a first type and of a second type. Each set may have a same total circumferential length, but the marks of a given type may have at least two different total circumferential lengths within a set of marks, or may be distinguishable by the relative position of marks of the different type to each other. The adjacent marks of the first and the second type may also form a code pattern that can be used for identifying the features. A method for adjusting the rotational orientation of the disc based on detecting the widths of the sectors is described.
