摘要

The construction of a receiving apparatus for receiving a broadcast from a plurality of broadcasting providers is simplified. In a digital television signal receiver for receiving a broadcast from a plurality of broadcasting providers, of the function blocks which constitute the receiving apparatus, a block used in common irrespective of the broadcasting provider is formed as a common block, and a block different from one broadcasting provider to another is formed as an independent block. These blocks are connected to each other through an IEEE1394 interface, and the common block is shared among the plurality of blocks which are not used in common, so that a receiving process is performed.
