  Furthermore, if it is determined in step B2 that the mobile phone terminal 10 is not currently in a power supply state by an external power supply (step B2 (No)), the recording reservation data stored in the recording reservation memory 22c is stored in the recording reservation data. Based on this, the time length of the program to be recorded is obtained (step B7), and it is determined whether the time is within a predetermined time length or longer (step B8).

  Even when it is determined that there is not a sufficient power supply state by the external power supply and a limited power supply state by only the rechargeable battery 28 (step B2 (No)), the time length of the program reserved for recording is long. If it is determined that the time is within the predetermined time length (steps B7 and B8 (Yes)), the television broadcast program reserved for recording by the television receiving antenna 15b and the digital broadcast receiving unit 25 of the terminal 10 itself is stored. Reception is performed and recorded in the television recording memory 22b (step B8 → B6).

  Further, when it is determined that the external power supply is not in a sufficient power supply state and the rechargeable battery 28 is in a limited power supply state (step B2 (No)), the time length of the program reserved for recording Is determined to exceed the predetermined length of time (steps B7 and B8 (No)), the liquid crystal display unit 12 displays a disabling message notifying the user that recording is impossible because there is no external power source connection. (See FIG. 12B) (step B9).

  Even when such a message indicating that recording is impossible is displayed, if it is determined that the forced execution of recording is instructed by menu selection in the recording mode (see FIG. 12C), this terminal The TV broadcast program reserved for recording is received by the TV receiving antenna 15b and the digital broadcast receiving unit 25 of 10 itself and recorded in the TV recording memory 22b (step B10 → B6).

  Further, after the recording impossible message is displayed (step B9), for example, when the forced execution of the recording is not instructed within a predetermined time (step B10 (No)), it is based on the current recording reservation data. The recording process is canceled (step B11).
