PROBLEM TO BE SOLVED: To eliminate uneasy feeling due to decoding stop for a long time by controlling decoding display in accordance with a received radio wave state when error correction is impossible. SOLUTION: A front end means 2 correcting the reception error of received data from a redundant code for error correction and raising/outputting the reception error flag of a packet when it cannot be corrected, a first counter means 10 counting the number of the error packets of received information for the past prescribed time from latest information of a specified received program and calculating the average number of the error packets on one frame and a second counter means 11 counting the number of the error packets of one latest frame information on the specified received program are provided. Furthermore, a comparison means 12 comparing the outputs of the first counter means 10 and the second counter means 11, and decoding means 4 and 5 decoding received information are provided. Thus, uneasy feeling that decoding stop continues is prevented, and a picture having comparatively few errors compared to a case when all received information are decoded and displayed can be displayed. |
