description A method for detecting abnormality of an encoder includes: executing an acquisition process for acquiring multiplexed data from the encoder that multiplexes encoded data obtained by performing an encoding process for multimedia data including moving picture data and audio data, and outputting the multiplexed encoded data; executing a first detection process for detecting, based on a packet identifier included in each of packets included in the acquired multiplexed data, at least either one of first packet corresponding to the moving picture data and second packet corresponding to the audio data from the multiplexed data; and executing a second detection process for detecting an abnormality of the encoder depending upon whether or not a detection number corresponds to a predetermined number, the detection number indicating at least either one of the number of times of the detecting the first packet and the number of times of the detecting the second packet.
