ABSTRACT:
In one aspect a transmission system with a transmitter which can be connected to a video source and a receiver linked to the transmitter via at least four circuit pairs, to which receiver a playback device can be connected is provided. Data is usually exchanged digitally between a graphics card in a personal computer and an LCD display module. The personal computer transmits a digital R, G, B video signal to the LCD display module via a special, so-called DVI (Digital Video Interface) cable. This DVI cable is also provided to transmit so-called DDC (Display Data Channel) data, which particularly comprises specification information of the LCD display module. A transmission system is proposed, which simplifies a connection of an LCD display module to a personal computer and with which the DVI cable can be dispensed with.
