Abstract
Abstract A portable electronic video recording system comprises a portable electronic camera 1 and a portable video cassette recorder 3 which can be carried in a case 5, which camera and recorder cooperate with each other via transmission means for transmitting means for transmitting signals and, if desired, the power supply voltage. The system further comprises switching means for switching the power supply voltage on and off and for controlling the various functions of the system, which switching means comprise at least stand-by switching means which switch the electrical power supply on and off and other switching means which prepare the system for making a recording, and recording switching means which serve for controlling the recording function of the system. The case 5 is provided with a camera compartment 14 for accommodating and carrying the camera 1, so that the case serves not only for carrying the video cassette recorder but also as an everready case for the camera. Since the transmission means are constantly connected to the other system parts, also when the camera is placed in the case, and after the stand-by switching means have been switched on, the camera is ready to make a recording as desired immediately it has been taken out of the case.
