摘要： The present invention provides a digital broadcast receiver which can prevent the user from mistaking blackout status for trouble with the digital broadcast receiver as much as possible. In cases where the AV decoder 4 cannot receive the IDR frame because of a bad broadcast transmission, it is possible that nothing is displayed on screen of the display section 36. In this invention, when in an undisplayable status because of a bad broadcast transmission (the CPU 13 receives the impossiblity notification of the decoding from AV decoder 4, the error correction from the tuner 2 or the CPU 13 decides that broadcast wave receiving is impossible based on the receiving electrical field strength, etc.), the display section 36 displays a message by the OSD circuit 12. This message describes the undisplayable status, for example, “Cannot display video because of a receiving failure,” when there is a bad broadcast transmission.
