In an encoded stream decoding device, a storage amount checking circuit confirms that a sufficient amount of stream has been stored in a buffer circuit. Thereafter, a control circuit starts repeatedly outputting a control signal to a decoding circuit to instruct the decoding circuit to perform a variable-length decoding process. If, by iterating the decoding process, the total amount of a consumed stream in the buffer circuit 11 is caused to be higher than or equal to a threshold set in a threshold setting circuit, a disabling circuit generates a decoding disable signal having a value of “1,” and outputs the decoding disable signal to the control circuit. When receiving the decoding disable signal, the control circuit outputs, to the decoding circuit, a control signal for instructing to stop the decoding process, so that the decoding circuit stops the decoding process.
