Abstract

The construction of a receiving apparatus for receiving a broadcast from a plurality of broadcasting providers is simplified. In a receiving apparatus 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.

First claim

The invention claimed is:

1. A signal receiving system comprising:
a receiver configured to receive a scrambled signal corresponding to a first broadcasting provider or a second broadcasting provider;
a filter to extract information of a desired program from the scrambled signal to generate an extracted scrambled signal, the filter extracting only packets for the desired program from a transport stream, in which the desired program is included, by referring to a packet ID;
a…
