Description

  The present invention relates to a remote control operation in a television receiver capable of simultaneously displaying images from a plurality of image sources on two screens.

  With the recent digitization of broadcasting, a huge number of channels can be received by a television receiver (hereinafter also referred to as a television). There are also a wide variety of external devices that are presumed to be connected to a television such as a video recorder, a hard disk recorder, a DVD recorder or the like, a DVD player, or a home game machine.

  In response to these trends, home television receivers not only receive traditional analog terrestrial broadcasts, but also various video sources such as terrestrial, BS, CS digital broadcasts, and external devices, There is a demand for efficient switching and display in response to user needs.

  In general, a television receiver is operated by a remote controller from a position away from the main body, but the operation tends to be complicated due to a large number of buttons related to channel selection operation, input switching operation buttons, and the like. As a solution to this, the keys with numbers 1 to 12 that correspond to analog terrestrial broadcasting stations function as one-touch direct channel selection buttons. Dedicated buttons are called direct channel selection buttons (hereinafter referred to as direct channel selection buttons), and users can register arbitrary channels for each button, allowing remote control of frequently viewed channels. The function of selecting with the touch of a button is realized.

  On the other hand, two different video signals (video sources) are selected from the video signals from multiple tuners and the video signals from multiple external devices input via the external input terminal, and displayed side by side on the screen simultaneously. Television receivers having a two-screen display function have been commercialized.

  In general, the two-screen display function is a function that displays a child (sub) screen that is the second screen separately from the parent (main) screen. The main screen and the sub screen on the other side are displayed in substantially the same size. Separately from this, a sub screen is displayed on a part of the display screen forming the main screen area, and an image is displayed independently on the main screen area and the sub screen area (hereinafter referred to as PinP). There is provided a television receiver with (referred to as “Picture in Picture” function).

  In a television having a two-screen display function and / or a PinP function, the two screens have a master-slave relationship, and one of them is the target of direct operation by the user, and at the same time the sound is output, The other is displayed for the purpose of monitoring the contents without outputting sound. For example, by displaying a drama program on the main screen and outputting sound, and simultaneously displaying a news program on the sub screen (without sound), you can watch the drama with sound while checking the headline of the news program The use is made.

  To operate the status of two screens, switch to two screens (change from one screen to two screens, return from two screens to one screen), switch active screen (sound, and continue to operate) The remote control has an operation button that allows you to switch between the two video sources.

  In general, in a television receiver having a two-screen function, the function of the direct channel selection button at the time of two-screen display is the same as that at the time of one screen only for the screen to be operated. That is, only the main screen is operated by the direct channel selection button, and the other sub-screen is not affected by the operation unless the operation target is switched.

  In order to perform a two-screen display consisting of two desired video sources from a normal one-screen display using a television receiver having a two-screen function, the user can use the video source ( 1) Select → Select the video source you want to display (2) → Switch to two screens (two screens are composed of the two video sources selected immediately before) or switch to two screens → The video source you want to display A complicated operation is required in the procedure of selecting (1) → switching an active screen → selecting a video source (2) to be displayed.

  In addition, the two video sources and two-screen states obtained in this way can be easily destroyed by user operations such as channel selection, input switching, and single-screen display. Therefore, it is necessary to operate while considering the necessary procedure, or to give up and follow the same procedure from the beginning.

  An object of the present invention is to provide an image display device that improves the usability of a direct channel selection button that can execute an operation of a two-screen state together with selection of an image source.

In order to solve the above problems, the present invention employs the following configuration.

(Example 1) When the direct channel selection button has the function to select a channel dedicated to news, the video source currently being viewed is left as it is, and the channel is selected as a secondary channel, and the headline is read and read. If you have a request to keep watching,
・ As the setting to select the news channel as a sub screen, make sure to keep the video source currently being viewed as it is, and make it a two-screen as a sub-screen. Set to “Yes”.

-In the case of a single screen, the screen that is being watched is switched to the news channel, and in the case of the dual screen, the setting for selecting the news channel as a sub screen is set in "Detailed settings", "Change the status of the single screen and double screen No ”→“ When 2 screens, “news channel” is set as sub screen ”.

(Example 2) When a channel dedicated to a movie is selected and always viewed on a large screen, “Always set to one screen” is set in “Detail setting”.

(Example 3) When two recording devices are connected at the same time and their screens are monitored at the same time, “Register two screens” in “Detail Settings” → “Video 1” with “Video 1” as the main screen "Register as a sub screen".

  Next, the operation when the direct channel selection button whose operation is set by the user operation on the setting screen described above is pressed will be described with reference to FIG. FIG. 9 is a flowchart showing an operation when the direct channel selection button set by the user operation on the direct channel selection button setting screen is pressed.

  The command instructed by the user using the remote control is received by the light receiving unit, and the CPU determines which button has been pressed. It is determined that the instruction from the remote control is that the direct channel selection button has been pressed (S1), and the direct channel selection button has a special meaning (number input such as zip code, input of settings on the registration screen of the direct channel selection button) If it is a situation that is effective as a user operation of direct channel selection (S2), it is determined that the instruction is for selecting a registered video source, and the process proceeds to the next step.

  Next, the setting contents of the pressed direct channel selection button are read (S3). First, the first flag is used to read whether or not to make two screens. (1) “Do not change the state of one screen or two screens”, (2) “Make sure to make one screen”, (3) “Make two In the case of (2) and (3), the current screen status (whether it is one screen or two screens) is acquired (S6, S4). S8) If necessary, the screen state is changed to one screen or two screens (S7, S9).

  Subsequently, if the current screen state (whether it is one screen or two screens) resulting from the execution result of the previous procedure is a single screen, that screen is the target of operation and the selection registered in the direct channel selection button. The station or input switching operation is executed (S18), and the process ends. In the case of the two screens (S10), the determination of the registered contents is continued. When the two screens are registered (S11), the main screen and the sub screen are set as the respective video sources (S12), and the process ends.

  If only one screen is registered, the second flag of the setting contents reads out whether the main or sub screen will be affected when the second screen is displayed, and the operation target (main screen or sub screen) (S13 to S16), the video source is set for the operation target by channel selection, input switching, etc., and a desired result is obtained.

  The above describes the operation of a television having a two-screen function, but a similar function can be provided for a television having a sub-screen function.

  On the other hand, in the present invention, in addition to the above-described conventional operation of the direct channel selection button, image source information is assigned to each of the direct channel selection buttons as needed on the main screen and the sub screen. The following two attributes related to the two-screen operation can be set.

  That is, the attribute (1) is an attribute indicating whether or not the state of one screen or two screens is changed. Specifically, the attribute (1) is always one screen, is always two screens, is one screen, two It is possible to set that the state of the screen is not changed. In addition, when the attribute (2) is set to “double screen” in the above attribute (1), or when “do not change” is set and the current state is the dual screen, the main screen is displayed. It is an attribute of which one of the sub-screens it acts on. Specifically, it can be set to act on the main screen or on the sub-screen.

  As described above, each of the direct channel selection buttons independently has information on the information and operations of the two image sources, so that the operation when the direct channel selection button is pressed can be selected as follows, and television reception is performed. Improve the operability corresponding to the two-screen function of the machine.
