Problems solved by technology

[0005] However, with this technology, when there is an incoming call while the user is watching a TV program, the user must give up watching the TV program, and it is necessary to operate the cellular phone to switch the cellular phone to a telephone conversation mode
It will be troublesome for the user to set the cellular phone to the phone talk mode every time there is an incoming call, and the user may make mistakes in the operation
[0006] Meanwhile, there remains a problem that the cellular phone cannot receive TV broadcast waves once the cellular phone is set to the phone call mode.
Consideration will be given to having a cell phone display a TV program while talking on the cell phone, but receiving TV broadcast waves may often prevent phone conversations

[0031] Embodiments of the present invention will now be described with reference to the drawings. Figure 1A and 1B Shown are a front view and a rear view of the appearance of the cellular phone 1 according to the embodiment of the present invention in an opened state. A cellular phone 1 according to an embodiment of the present invention includes a main body portion 1b and a cover portion 1a, both of which are connected to a hinge (not shown) and can take two positions, namely Figure 1A and 1B Open position and closed or folded position shown. That is, the main body portion 1b and the cover portion 1a connected to the main body portion 1b by a hinge take an open position or a folded position relative to each other. The cover portion 1a is provided with the display unit 13 on its front face which faces the front face of the main body portion 1b when the cellular phone 1 is held in the folded state. Meanwhile, the main body portion 1b is provided with a key input portion 14 ...

[0097] In the cellular phone according to the first embodiment of the present invention, the phone is configured to switch to a phone call mode and display an incoming call screen in order to perform phone call processing before other processing. Only the speaker and microphone of the cell phone are necessary for a telephone conversation, so the display unit can be used to display television images while the cell phone is used for speaking.

[0098] In short, the TV sound cannot be heard with this cell phone. will refer to Figure 10 The flow chart of the figure describes the processing performed in the cellular phone. Figure 10 The flow chart corresponds to Figure 4 flow chart. has been executed image 3 After the processing shown, will execute Figure 10 , and then perform the processing of step 309.

[0105] In the cellular phone according to the second embodiment, the television image is kept displayed on the display unit in the telephone conversation mode, but the cellular phone may be modified so that the display area of ​​the display unit is divided into two areas, one area for displaying TV image, while another area is used to display caller data.

[0106] The processing performed in the improved cellular phone will be described below with reference to the flowchart shown in FIG. 11 . Figure 12 An example of the display screen is shown in .

[0107] exist Figure 12 , the display area of ​​the display unit 13 is divided into two areas 13a, 13b. Area 13a occupies more than half of the entire display area of ​​display unit 13 and is used to display television images, while another area below occupies less than one-third of the entire display area of ​​display unit 13 and is used to display incoming call display and call or number.

Abstract

In a cellular phone which receives a television signal by means of a TV receiving section (200), when the cellular phone is brought to an open state after detecting an incoming call while receiving a television signal with the cellular phone kept in the closed state, the television receiving operation ceases automatically for communication by telephone, and thereby the user is not required to execute a troublesome operation to quit receiving the television signal. The control section (22) in the cellular phone does not cease receiving the television signal while the user is talking on the phone and outputs telephone talking voice in place of the television sound. Therefore, the user can enjoy watching the television image while talking on the phone. Further, since the cellular phone displays on a display section (13, 16) the television image and caller's information simultaneously, the user can confirm the caller's information.

Description

technical field [0001] The present invention relates to a cellular phone, and more particularly, to a cellular phone having a function of receiving television broadcast waves. Background technique [0002] A technique of embedding a television broadcast wave reception function in a cellular phone has been proposed. The proposed cellular phone is provided with a tuner for receiving surface digital broadcast waves to obtain encoded video and audio data, and a memory card or built-in memory for storing encoded image and audio data. In this cellular phone, encoded video and audio data read from a memory card or built-in memory, or encoded video and audio data supplied from a tuner are decoded to display video images on a display of the cellular phone, and The speaker outputs sound. [0003] Cellular phones with reception of television broadcast waves may create new problems. For example, when there is an incoming call while the user is watching a television program, and the u...
