PROBLEM TO BE SOLVED: To provide a TRIAX interface for a video camera and a base station which is capable of transmitting/receiving a video signal of a high image rate without sacrificing a maximum available length of a cable. SOLUTION: The TRIAX transmitter interface comprises a video signal input port (2), a first modulator (4) for modulating a luminance component ([Y]) of a video signal received at said input port (2) onto a first carrier, a second modulator (5) for modulating a chrominance component ([B-Y], [R-Y]) of the video signal onto a second carrier, and a TRIAX output port (10) for outputting said modulated carriers to a TRIAX cable (11), wherein the first modulator (4) is a quadrature modulator (4) adapted to modulate luminance components of two video image lines simultaneously and in quadrature onto the first carrier.
