Abstract
A portable television camera and tape recorder combination wherein, prior to recording a scene, the signal of a bar generator is first recorded on a tape for test and reference purposes. After the preparations for recording the scene, wherein use is made of a view finder, the bar generator must be switched off and the camera signal must be recorded on the tape. By way of non-disturbing indication in the image on the view finder that the bar generator is switched on, the signal thereof is added, after differentiation, to the camera signal and displayed on the view finder.
