Abstract
The invention relates to the ability to connect items of electrical apparatus and to allow the transfer of data signals between them. In particular, the invention relates to the connection of at least three items of electrical apparatus via scart connections and, the transfer of data signals between the first and third items of apparatus via the second item of apparatus such that even if the second item of apparatus is switched off from its mains power supply, a circuit within the apparatus still be powered via power supply provided via the scart connection to allow the passage of the data signal between the first and third items through the second item. This therefore allows savings in electricity and overcomes the need for the second item of apparatus to be kept connected to a mains power supply at all times which is conventionally the case.
