In an application scenario of playing a live program, a display device may simultaneously display channel information of a program and a channel where the currently played program is located, where the channel information may include information such as a channel name of the channel where the currently played program is located, a program name of the currently displayed program of the channel, and a program name of the currently played program of the channel in a future period of time. But if the user wants to watch the channel information of other channels, the channel change operation is required. When the user changes the channel, the program displayed by the display device changes, and the user experience is poor.

In order to solve the above technical problem, on the basis of the display device shown in the above embodiment, the present embodiment further improves the display device, where the display device at least includes: a controller and a display. The operation of the display device is described below with reference to the following specific drawings:

fig. 5 is a flowchart illustrating interaction between a display device and a user according to a feasible embodiment. In the present application, a display device includes at least a display and a controller.

Wherein the display comprises a first region and a second region;

in the present application, the first area is used for displaying programs, and the second area is used for displaying channel information;

the program referred to in the present application is a live program, and the signal source of the program may include a satellite signal received by a set-top box, or a network signal transmitted through a network. Each program corresponds to a channel, for example, a news simulcast program is being broadcast at 19 o' clock CCTV-1, and then the channel corresponding to the news simulcast program is CCTV-1.

In this application, the channel information is information for explaining some attributes of the channel broadcast program or channel. For example, the channel information may include channel attributes such as a channel name, a channel number (note that the channel number is not the only attribute of a channel, and the channel number may change according to the channel searched by the display device). The channel information may also include program information about programs being broadcast on the channel, where the program information may include a program name of a program being broadcast, a program broadcast schedule, and a program name of a program that needs to be broadcast on the channel for a future time. It should be noted that, this embodiment merely introduces several kinds of channel information by way of example, and in the process of practical application, the channel information may be, but is not limited to, the above several kinds of information, and all the information that plays a role in explaining some attributes of a channel broadcast program or a channel may be applied to the technical solution shown in this embodiment as the channel information.

The display will be described with reference to the accompanying drawings. Fig. 6 is a schematic diagram of a display device according to a possible embodiment. It can be seen that the display shows content comprising a first area 61 and a second area 62. The first area is used to show the currently playing program and the second area 62 is used to show the channel information. In this embodiment, the channel information may include a program name of a currently playing program, a playing schedule of the program, a channel number, and a program name that needs to be played in a future period of time on the channel.

The user performs step S51 to output a channel information call instruction.

In this embodiment, the channel information retrieval instruction is triggered by the user, and there are various ways for the user to trigger the channel information retrieval instruction. As a feasible implementation manner, the user may trigger the channel information invoking instruction by touching a preset key on the remote controller, which is not limited in this embodiment, the preset key may be an original key on the remote controller, for example, an "up" key or a "down" key, or an additional key added on the basis of the existing remote controller key. As a feasible implementation, the user may trigger the channel information retrieval instruction by the user voice. The embodiment merely describes several implementation manners of triggering the channel information retrieving instruction by the user, and the implementation manners of triggering the channel information retrieving instruction in the process of practical application may be, but are not limited to, the above two implementation manners.

If the second area shows the first channel information, the controller is configured to perform a step S52 of retrieving the second channel information in response to a user' S operation of retrieving the channel information.

In this embodiment, when the user does not issue the channel information calling instruction, the display only shows the first area, that is, the display plays the program in a full-screen manner. As a possible embodiment, when the second region of the display shows the channel information (the second region may show the first channel information or the second channel information), in order to avoid that the channel information exists for a long time and affects the viewing effect of the user, the controller may count the showing time of the channel information, and when the showing time is equal to the preset time, the controller controls the display to no longer display the channel information.

In this application, the first channel information is channel information of a first channel, the first channel is a channel where a first region display program is located, the second channel information is channel information of a second channel, and the second channel is different from the first channel. For example, the second channel may be, but is not limited to, a previous or next channel of the first channel.

In this embodiment, the previous channel number is the channel number-1 of the first frequency. The next channel number is the channel of channel number +1 of the first frequency. For example, referring to fig. 6, the channel number of the channel in which the first region is shown in fig. 6 is 74, and in this embodiment, "7 food network" is the first channel information. The second channel is a channel with a channel number of 73 or a channel with a channel number of 75.

The controller is configured to execute step S53 to control the content presented in the second area to be switched from the first channel information to the second channel information.

The contents of the second area will be described with reference to specific examples.

Fig. 7A is a diagram illustrating a change of a display device before and after an operation of a user calling channel information in a case where the first channel information is displayed in the second area according to an embodiment. It can be seen that, in the initial state, the first area 73A shows the program broadcast by the channel 74, and the second area 74A shows the channel information of the channel 74, which can be referred to as an effect 71A in fig. 7A. In this embodiment, the user touches the "up" button of the remote controller, and the corresponding remote controller outputs the previous channel information invoking instruction. In response to the previous channel information retrieving command, the controller retrieves the channel information of channel 73 and controls the second area 75A to display the channel information of channel 73, at this time, the first area 73A still displays the program played by channel 74, which can be referred to as an effect 72A in fig. 7A.

Fig. 7B is a diagram illustrating a change of a display device before and after an operation of a user calling channel information in a case where the first channel information is displayed in the second area according to an embodiment. It can be seen that, in the initial state, the first area 73B shows the program broadcast by the channel 74, and the second area 74B shows the channel information of the channel 74, which can be referred to as an effect 71B in fig. 7B. In this embodiment, the user touches a "down" key of the remote controller, and the corresponding remote controller outputs a next channel information invoking instruction. In response to the next channel information retrieving command, the controller retrieves the channel information of channel 75, and controls the second area 75B to display the channel information of channel 75, and at this time, the first area 73B still displays the program broadcasted by channel 74, which can be referred to as an effect 72B in fig. 7A.

The embodiment of the application shows a display device. The display device includes a controller and a display. The display comprises a first area and a second area, wherein the first area is used for displaying programs, and the second area is used for displaying channel information. And if the second area displays the first channel information, responding to a channel information calling instruction output by a user, and controlling the content displayed in the second area to be switched from the first channel information to the second channel information by the controller. In the process, the first area always shows the program played by the first channel. It can be seen that the display device shown in this embodiment may control the second area to display channel information of other channels besides the first channel when the first area displays a program broadcast by the first channel. The user can watch the program played on the first channel and watch the channel information of other channels at the same time, so that the user experience is better.

In the prior art, in response to a user touching a first key on a remote controller, a controller controls a display to display a channel interface, where the channel interface is used to display all channels searched by the display device. The first key may be, but not limited to, an "up" key, and in order to achieve the effect of multiplexing the keys of the remote controller, as a feasible embodiment, the controller may respond differently to the same control instruction output by the remote controller according to different display contents of the display. The operation of the display will be described with reference to the accompanying drawings.

Fig. 8 is a flowchart of a channel information retrieving method according to an embodiment. The present embodiment further improves the display device shown in the above embodiment, wherein the controller is further configured to execute steps S81 to S84:

if the second area does not show the first channel information, in response to a channel information call instruction, the controller is configured to execute S81 to identify a key value corresponding to the channel information call instruction;

fig. 9 is a schematic diagram of a display device in an application scenario in which the second area does not show the first channel information according to a possible embodiment.

In the present application, a key value identification manner that is commonly used in the art may be adopted as an implementation manner for identifying a key value corresponding to a channel information retrieval instruction, and the applicant does not make much limitation here.

In this application, the channel information retrieval instruction may correspond to a plurality of key values, for example, the channel information retrieval instruction is to retrieve channel information of a previous channel, and the channel information retrieval instruction may correspond to one key value; the channel information calling instruction is the channel information for calling the next channel, and the channel information calling instruction can correspond to another key value.

If the key value is the first key value, S82 controls the display to display a channel interface, where the channel interface is used to display all channels searched by the display device.

In the application, the first key value is a key value for calling a key corresponding to the channel interface on the remote controller, and different manufacturers may call different keys corresponding to the channel interface, for example, in some feasible embodiments, the key corresponding to the channel interface may be an "up" key. The call channel interface corresponding key may be a "down" key in some feasible embodiments. The applicant hereby does not make any undue restrictions.

The channel interface is described below with reference to the specific drawings. Fig. 10 is a schematic diagram of a display device provided according to a possible embodiment. It can be seen that the display shows a channel interface 101 showing channel names that the display device can search through to all channels.
