A system ( 200 ) and method are described for exchanging data such as software updates, menus and digital AV content (e.g. MPEG2 streams) between components ( 202, 206 ) of a home entertainment system ( 200 ) interconnected using analogue AV connections such as phono/RCA or (preferably) Scart ( 208, 214 ). A first component ( 202 ) indicates ( 222 ) to a second component ( 206 ) that a data exchange is planned utilising one or more available analogue AV connections ( 220 ). In response, the second component ( 206 ) adapts its processing to accommodate the data exchange, for example routing and processing exchanged data instead of handling it as analogue AV content. In this way, existing analogue AV connections ( 208, 214 ) may be used to transfer data from one component to another in a home entertainment system without perturbing normal analogue AV operation whilst saving standardisation and deployment costs associated with defining new connectors and cordsets for such data transfer.
