Abstract
This invention relates to controlling the power states in a multimedia system comprising a multimedia connector box including a multimedia source interconnected to a transmitter module, and a multimedia device including a receiver module interconnected to a multimedia sink, wherein the transmitter and the receiver modules interface the multimedia connector box and the multimedia device via multimedia interfacing means. A signal detector detects the signal activity between the power sources of the multimedia system for determining the current power state of the power sources, and a power switching mechanism adapts the power states of the transmitter and receiving modules to the power states of the power sources.
