Abstract

A 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.

Claims

1. A portable video recording system, particularly for amateur video recording operations and the like, comprising a video recording station, and an independent and self-contained portable video camera station, the latter being of a size to be readily manually carried on the person and comprising a video camera, a transmitter, for transmitting signals by transmission of a high-frequency carrier signal, means operatively connected to the camera for supplying thereto necessary synchronizing and control signals, whereby there will be produced at said camera video signals in the form of a plurality of scanned lines of video content which are supplied to said transmitter, together with necessary control signals from said signal supply means, for modulation on such high-frequency carrier signal and transmission thereby, manually actuatable means on said camera for controlling the start-stop operation of said camera station, and self-contained power supply means for said camera station;

said recording station comprising means for receiving transmitted signals from said camera station, means connected to said receiving means for deriving the video and control signals from the received signals, video-tape recording means to which said received signals are supplied for recording thereat, means at said recording station for supplying to said recording means synchronizing signals corresponding in character and time to those employed in the camera, means for controlling the start-stop operation of said recording means, means operatively connected to said receiving means and to said recorder-controlling means, responsive to start-stop signals from said camera station received by said receiving means, and means for supplying power to said recording station; and

means at said camera station, responsive to actuation of said manually actuatable start-stop means thereat for initiating transmission of start-stop signals to said recording station, operative to control said recorder start-stop control means thereat, whereby said recorder is operatively recording only when said camera is in operation.

2. A portable video camera station, for use with a cooperable video recording station connected therewith by only a wireless link and adapted to receive, process and record radiated signals from such camera station, and including start-stop means controlling the recording operation under control of the camera station, particularly for amateur video recording operations and the like, in the form of an independent and self-contained portable video camera station, of size to be readily manually carried on the person and comprising a video camera, a transmitter, for transmitting signals by transmission of a high-frequency carrier signal, means operatively connected to the camera for supplying thereto necessary synchronizing and control signals, whereby there will be produced at said camera video signals in the form of a plurality of scanned lines of video content which are supplied to said transmitter, together with necessary control signals from said signal supply means, for modulation on such high-frequency carrier signal and transmission thereby, manually actuatable means on said camera for controlling the start-stop operation of said camera station, and means responsive to actuation of said manually actuatable start-stop means for initiating transmission of signals to such a recording station for controlling the start-stop control means thereat, whereby said recorder is operatively recording only when said camera is in operation, and self-contained power supply means for said camera station.

3. A video recording station, for use with and control by a cooperable portable video camera station connected therewith by only a wireless link and adapted to produce video and control signals and transmit the same to the recording station for use in recording thereat, particularly for amateur video recording operations and the like, comprising means for receiving transmitted signals from such a camera station, means connected to said receiving means for deriving the video and control signals, from such received signals, video-tape recording means to which such received signals are supplied for recording thereat, for supplying to said recording means synchronizing signals corresponding in character and time to those employed in such a camera, means for controlling the start-stop operation of said recording means, means operatively connected to said receiving means and to said recorder-controlling means, resonsive to start-stop signals from such a camera station received by said receiving means for controlling said start-stop control means, whereby the recorder start-stop operation is controlled by such a camera station and said recorder is operatively recording only when such camera is in operation, and means for supplying power to said recording station.
