An input/output interface is provided in which a logical value is expressed by an order that transition edges appear in a plurality of transmission signals transmitting respectively on a plurality of signal lines (DA, DB, DC, DD). Otherwise, the logical value is expressed by a time difference between the transition edge of the transmission signal transmitting on the signal line and a transition edge of a standard timing signal. Therefore, a large amount of data can be transmitted through one signal line. Since a large amount of data can be transmitted by one transmission, it is possible to substantially increase the data transfer rate. Since only a small number of the signal lines are necessary, it is possible to reduce the number of input circuits and output circuits of the transmission signals, to reduce power consumption, and to reduce the wiring area of the signal lines. |

This invention relates to a data decoding apparatus and data decoding method which perform maximum likelihood decoding by means of a simple construction, and which can be applied for example to a videotape recorder or optical disk device. In the data decoding apparatus or data decoding method a logic level inversion timing during one clock interval is detected from an input signal, a provisional identification result (22) of identifying the input signal is corrected by effectively one clock identification error, the number of state transitions which can be obtained from the input signal is limited based on this corrected provisional identification result, and the most probable state transition of these limited state transitions is detected to output an input signal identification result. |
