ELECTRONIC DEVICE

摘要

A video conversion device (11) can be connected to a conventional video camera battery pack (12). Device (11) comprises a body (13) containing electronic circuitry for conversion of a High Definition Multimedia Interface (HDMI) signal fed through input terminal 14 to a Serial Digital Interface (SDI) signal which is outputted through output terminals (15). One side of body (13) is provided with four L-shaped slideway formations (19) designed to receive slides on a battery plate of a video camera to form a push-on physical connection with the camera. The other side of body (13) is recessed and provided at the edges of the recess with four lugs or slide formations which are complementary to the slideway formations (19) and identical to the formations of the video camera battery connection plate. Accordingly they can be fitted into the slideways formed in the base of battery pack (12) in identical fashion to the slideway slots (19) in the conversion device. Accordingly the battery pack (12) can be quickly fitted to the conversion device (13) via a push-on connection and the conversion device similarly fitted to the camera battery plate by another push-on connection. The battery pack supplies power to the circuitry of the conversion device through terminals in the recessed side of body (13) and power is supplied via the conversion device to the camera through terminals (20).
