Portable terminal device

Abstract

There is provided a mobile terminal device capable of showing a television broadcast to a user even if the battery remaining amount is small when the television broadcast is being displayed or to be displayed and performing operation intended by the user. The mobile terminal device (100) includes a TV broadcast reception unit (101) for receiving a television broadcast signal, a TV broadcast processing unit (102) for decoding a television broadcast signal stream received, a power management unit (111) for detecting the battery remaining amount of a battery (112) and reporting it to a control unit (109) at a predetermined time interval, and the control unit (109) for instructing another device to record the television broadcast or the TV broadcast processing unit (102) to lower the display frame rate when the battery remaining amount of the battery (112) has become a predetermined amount or below.

Description

technical field [0001] The present invention relates to mobile terminal devices such as mobile phones and mobile information terminals, and more particularly to mobile terminal devices that receive and display television broadcasts. Background technique [0002] In recent years, for mobile terminal devices such as mobile phones and mobile information terminals, models capable of receiving and displaying television broadcasts have gradually appeared as the devices have become smaller and more functional. Furthermore, with regard to portable audio-visual devices, portable audio-visual devices that record video while viewing and listening to television broadcasts are appearing as devices become smaller and more multifunctional. [0003] With these mobile terminal devices and portable audio-visual devices, there has been a problem that, since a storage battery is used as a power source, television broadcasts cannot be displayed once the remaining amount of the battery decreases....

AI Technical Summary

Problems solved by technology

[0003] For these mobile terminal devices and portable audio-visual devices, there is a problem that, since a storage battery is used as a power source, once the remaining amount of the battery decreases, the TV broadcast cannot be displayed.

[0006] However, for the above-mentioned portable audio-visual device, there is a problem that the received video and sound are recorded in the memory card in the device itself, so once the remaining amount of the battery is less, it cannot be recorded in the memory card.

[0007] And, for the existing mobile phone with TV broadcast receiving function, there is a problem that this structure is, in order to reserve the specified battery capacity for the telephone function, once the remaining amount of the battery reaches a certain level or less, to forcibly end the display of the television broadcast

Therefore, the display of the TV broadcast will be ended in the middle of the program, and the TV broadcast at the end of the program cannot be watched.

[0008] And, like this, when the TV broadcast is being displayed or when the TV broadcast is about to be displayed, the operation when the remaining amount of the battery is small is fixed as a predetermined operation, and the user's intention cannot be reflected.
