There is disclosed a data storage apparatus for downloading data from datacast streams transmitted by a television broadcast system to a plurality of similar data storage apparatuses. The data storage apparatus comprises: 1) a storage medium for storing selected portions of the transmitted datacast streams; and 2) a content filtering processor for receiving a first datacast stream transmitted by the television broadcast system and detecting therein a plurality of datacast blocks, wherein the content filtering processor compares a first content parameter associated with a first one of the datacast blocks with at least one subscriber-specific parameter associated with the data storage apparatus and wherein the content filtering processor, in response to a determination that the first content parameter matches the at least one subscriber-specific parameter, stores the first datacast block in the storage medium.
