Abstract

A portable video recording system, particularly for amateur video reporting operations and the like, employing a camera station and a recording station which are physically separated from one another and connected over wireless links, the camera station being of a size to be readily manually carried on the person and designed merely to produce video and associated signals and transmit the same by radiation of a high frequency carrier, light or other signal to the recording station, and processed by receiving means thereat to derive the signals to be recorded, the recorder being operatively controlled from the camera station, whereby both the camera and the recorder of the remote recording station are under the control of the camera operator. Signals are also transmitted from the recording station to the camera station for indicating to the camera operator the operation of the recorder. Such indicating means may be a video monitor, an audio signal such as a tone signal, a visual signal such as an indicator light, or a combination thereof. Means also may be provided for effecting a selective switching, whereby a video signal may be returned to the camera either from the play-back head during recording operations, or from the recording head when the recording mechanism is not in operation.
