Abstract: A prompter system compatible with a camera having pan, tilt, and zoom functions is invented. According to the present invention, a prompter system compatible with a camera having pan, tilt, and zoom functions is constructed by storing a camera having pan, tilt, and zoom functions inside a camera attaching adapter and combining it with a prompter body.

Abstract: The present invention aims to improve convenience and comfort when installing and using an optical transmission device for transmitting video signals. The present invention provides an adapter and a base station for an optical transmission system that optically transmits analog video signals or digital video signals between the adapter-base station pair, the adapter and the base station comprising a lens controller and an intercom function, the optical transmission system operating connected devices.

Abstract: The present invention is directed to improve the convenience and comfort of the shooting site. According to the present invention, an adapter for an optical transmission system for optically transmitting analog video signals, digital video signals, control signals, audio signals, or a combination thereof between a pair of the adapters, wherein when the pair of the adapters are used with optical multiplexer/demultiplexers provided on both of the adapters, the optical multiplexer/demultiplexers being used to transmit the signals with multiple frequencies such as CWDM or DWDM through a single optical cable, at least one of an internal reflectance of the optical cable and light intensity in multiple frequency bands can be displayed on the display part.

Abstract: The present invention provides an optical transmission system for optical transmission of a signal between a first and a second adaptors, wherein the first and the second adaptors each include an input terminal, a determination unit, and a display unit, a first signal is input to the input terminal, the first signal being an analog video signal or a digital video signal, the determination unit is configured to determine whether the first signal is the analog video signal or the digital video signal and to determine a type of the digital video signal when the first signal is the digital video signal, and the display unit is configured to display information obtained in determination by the determination unit.
