Abstract

<P>PROBLEM TO BE SOLVED: To provide a receiving broadcasting station selecting method that facilitates switching to another input system and eliminates the need for operation and processing for inputs other than an input being viewed. <P>SOLUTION: A channel selecting unit 300a for "1seg" (one-segment broadcasting) 300A is actuated (S11) and then a channel selection picture is displayed at a display unit 11. Then a desired program to be viewed is selected (S12). When "mobaHO!"(satellite broadcasting service for moving body) 300B as another input is selected (S12: Yes), an operating system 301 quits "1seg" 300A and sends a command to a tuner driver 302 at the same time to turn off a tuner 202A (S13). Then "mobaHO!" 300B is driven and a command is sent to a tuner driver 303 to actuate a tuner 202B (S14). When the other input is not selected and a channel of "1seg" 300A is selected (S12: No), the channel of the tuner 202A is switched (S15). Then the channel selection picture is ended and a program is displayed (S16). <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a reception channel selection method for a television broadcast receiver, and more particularly to a reception channel selection method for a portable television broadcast receiver having a plurality of tuners.

  As a conventional technique, channels that can be selected from a plurality of broadcasting stations are collected and divided into several channel groups, and after selecting the channel group, the receiving broadcasting stations are selected in the order of selecting the channels included in the channel group. A channel selection method for determination is known (for example, Patent Document 1).

According to this channel selection method, a user must first characterize a channel group because a huge number of channels are divided into several channel groups based on channel selection information obtained through multiple broadcasting media of digital broadcasting. By selecting a channel group based on broadcast information such as BS (Broadcasting Satellite), CS (Communication Satellite), and terrestrial digital, it is possible to narrow down and limit a set of desired channels. After that, it is possible to determine the channel without switching each of a huge number of channels one by one by taking the step of selecting a desired channel from the channel group, and a button for channel switching installed on the remote control or the main body The number of times to operate is reduced, the time until the reception channel is selected is shortened, and a selection button for each broadcast input system is not necessary.

  However, according to the conventional channel selection method, in order to select a channel of another input system, it is necessary to repeat the channel selection operation each time, and there is a problem that the button operation efficiency is poor. In addition, since channel groups are generated by referring to all channels, it is necessary to always start up tuners for all input systems, and there is a problem that power consumption is large. Further, since a channel group is generated from all channels each time a channel is selected, there is a problem that the processing load on the television broadcast receiver is large.

  Accordingly, an object of the present invention is to provide a reception channel selection method in which the operation for switching to another input system is simple and no operation or processing is required other than the input being viewed.

A display step for displaying a channel selection screen on which a second input for receiving broadcast radio waves can be selected is displayed on the display unit, and a switching step for the operating system to terminate the first application when the second input is selected. And a starting step of starting a second application for controlling the second input by the operating system.

  According to such a method, since the second input is displayed in addition to the first input channel on the channel selection screen for the first input being viewed, the number of operation steps required for input switching is reduced. . In addition, since an input application that has not been viewed has not been activated, the processing load on the apparatus is reduced, resulting in power saving.

(3) Further, in order to achieve the above object, the present invention is configured such that the first input channel and the second input are activated while the first application for controlling the first input for processing the first broadcast radio wave is activated. A display step for displaying a channel selection screen on which a second input for processing broadcast radio waves can be selected is displayed on the display unit, and when the second input is selected, the operating system selects the first application and the first input. A switching step for terminating the first tuner for receiving the broadcast radio wave, a second application for controlling the second input by the operating system, and an activation for starting the second tuner for receiving the second broadcast radio wave And a receiving channel selection method comprising the steps of:

  According to such a method, in addition to the effect of (2), the input tuner that has not been viewed is not activated, so that power is saved.

(4) In order to achieve the above object, the first input channel and the first input channel of the first input for controlling the first input for receiving the first broadcast radio wave are activated. A display step for displaying a channel selection screen on which a plurality of inputs other than the first input can be selected are displayed on the display unit, and a second input among the plurality of inputs other than the first input is selected by the operating system. There is provided a receiving channel selection method comprising: a switching step for terminating a first application; and a starting step for starting a second application for controlling the second input by the operating system.

  According to such a method, the same effect as (2) can be obtained for a plurality of inputs.

(5) In order to achieve the above object, the first input channel and the first input channel of the first input for controlling the first input for processing the first broadcast radio wave are activated. A display step for displaying a channel selection screen on which a plurality of inputs other than the first input can be selected are displayed on the display unit, and a second input among the plurality of inputs other than the first input is selected by the operating system. A switching step for terminating a first application and a first tuner for receiving the first broadcast radio wave; a second application for controlling the second input by the operating system; and receiving the second broadcast radio wave. And a starting step for starting the second tuner. A receiving channel selecting method is provided.

  According to such a method, the same effect as (3) can be obtained for a plurality of inputs.

  According to the present invention, it is possible to simply switch to a desired channel and to save power in the apparatus.
