Beschreibung
Zusammenfassung:	An apparatus and method are provided for combining, transmitting and receiving two or more high definition video control signals, namely, DDC and HDCP over a single bi-directional optical fiber or a duplex optical fiber, wherein a source and a sink are in communication with each other through the apparatus, and wherein the sink includes EDID and HDCP registers. A single transmitter module and receiver module pair are provided wherein the transmitter module includes replications of the sink EDID and HDCP registers, whereby any write request from the source to the sink is stored within the replicated EDID and HDCP registers so that any read request from the source to the sink can be answered immediately. Optional high definition video control signals may also be included in the system including Hot Plug, CEC, 5V and infrared.
