摘要

A transmission system, comprising a transmitter (10) and at least one receiver (14) is configured to receive signals (12) transmitted therefrom. Broadcast data in the transmitted stream is accompanied by one or more applications defined in one or more data carousels formed of data file and directory objects sent in cycles with predetermined groups of file and directory objects being formed into respective modules at the transmitter and with each module being transmitted as a whole. For each object carousel defining the root hierarchy of the data objects there is transmitted in the stream a list of identifiers for the component data carousels respectively defining all or a part of the data objects associated with an application. The receiver (14) is arranged, on identification of a particular application to be recorded, to use the list of identifiers to identify and subsequently store the received file data and directory objects for that application.
