| 1. A digital broadcast receiver for receiving a digital broadcast signal carrying contents and also outputting contents based
on said received digital broadcast signal, comprising:
reception state detection means for detecting whether said digital broadcast signal can be received normally;
peripheral device communication means for communicating with an external recorded content reproducer capable of radio communication
with said digital broadcast receiver;
reproducer detection means for detecting said recorded content reproducer existing at a periphery of said digital broadcast
receiver by requesting an identification ID of said recorded content reproducer capable of connection via said peripheral
device communication means;
reproducer control means for controlling the reproduction by said recorded content reproducer by requesting reproduction and
transmission of said recorded contents by said recorded content reproducer that has said identification ID received via said
peripheral device communication means; and
switch-over means which is operable such that, if said reception state detection means detects that said digital broadcast
signal cannot be received normally, said reproducer control means issues a request for reproduction and transmission of said
recorded contents to said recorded content reproducer existing at the periphery detected by said reproducer detection means
and when said periphery device communication means receives said recorded contents transmitted from said recorded content
reproducer, outputting of content is switched-over from outputting of the contents of said received digital broadcast signal
to outputting of said received recorded contents, and when the outputting of said recorded contents switched-over is finished
and if said reception state detection means detects that said digital broadcast signal can be received normally, outputting
of content is switched-over from outputting of said recorded contents to outputting of contents of said digital broadcast
signal received normally.
