scope:

This part of IEC 933 defines an interface which is designed to enable the Electronic News Gathering (ENG) signals produced in a non-composite form to be sent through a parallel link between a camera and a portable Video Tape Recorder (VTR) which are separated by about 5 m to 10 m instead of being combined in a camera-recorder. This part of IEC 933 includes the electrical characteristics that the interface will have to satisfy in order to transmit the programme signals produced by the camera (audio and video components) and those fed back to the viewfinder (video, playback), as well as the operational controls and the monitoring indications. This specification includes only those characteristics considered to be essential to facilitate the interconnection of equipment produced by different manufacturers. In order to prevent damage due to incorrect connections, it is necessary to make sure that the equipment concerned complies with this specification, and, furthermore, that the additional connections provided by the manufacturers in the case of particular systems are not incompatible with this specification.
