Show moreA portable video recording system, particularly for amateur video recording operations and the like, employing a camera station and a recording station which are physically separated from one another and connected over a wireless link, 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 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 camera and the recorder of the remote recording station are under the control of the camera operator.

Show moreOne embodiment of video transducing system supplies a reproduced video signal with compensated amplitude response so as to exhibit a substantial phase advance for recorded half wavelengths less than the thickness of the magnetizable layer, and a phase correcting network is inserted between the playback winding and the playback amplifier. In a further embodiment, amplitude and phase are partially compensated such that there is a substantial amplitude fall off and a moderate phase advance at the highest frequencies of the useful range, and such that the leading edge of a step function when played back has an overshoot of approximately one to six decibels.
