A content receiver useable in a broadcast content distribution system includes a content source that broadcasts audio/video content for reception by content receivers with associated metadata defining links to other content for possible reproduction by the content receiver and information indicative of a category of each link. The content receiver is configured to generate link information for display in dependence upon received metadata relating to links having a subset of categories while reproducing the broadcast audio/video content, and includes a user control operable to select a link for which link information is currently displayed by the content receiver causing the content receiver to reproduce content defined by that link and a category memory storing category information defining the subset of categories, the content receiver configured to modify stored category information in dependence upon which links are selected using the user control. |
