Patent ID: 7953162

Claim:
A method for transmitting signals across a pair of wires, comprising: (a) transmitting differential signals across the pair of wires during a period of time when a device is in an active mode, the differential signals being transmitted across the pair of wires comprising high speed video signals, and the differential signals being transmitted across the pair of wires also comprising low speed serial clock (SCL) and serial data (SDA) signals embedded with the high speed video signals; and (b) transmitting two single-ended signals across the same pair of wires during another period of time when the device is in a sleep or standby mode, neither of the two single-ended signals comprising the high speed video signals, one of the two single-ended signals being transmitted across one of the wires comprising the low speed serial clock (SCL) signal, and the other one of the two single-ended signals being transmitted across the other one of the wires comprising the low speed serial data (SDA) signal.
