PROBLEM TO BE SOLVED: To provide a satellite digital broadcasting receiver for easily recognizing the cause of broadcasting (display) interrupt by reporting the changes in the reception level of broadcasting signals to a user. SOLUTION: An error in the transport packet of a reception channel is detected in an error correction part 3, and the result is obtained in an error number counting part 10. Then, when the obtained error number in a prescribed period becomes large, it is decided that a reception state is deteriorated, the reception state (reception level) at the time is processed in an OSD display part 9 and reported to the user by a display form corresponding to the error number in a display means provided in an IRD 1031 or a monitor screen, and the degree of the reception state is reported. Even if the condition becomes one where no output from a device is present and a monitor becomes only a black screen since reception is unavailable, the user decides that it is due to the deterioration of the reception level by knowing the reception state beforehand. |
