There are various ways to retrieve channel information, and as a feasible implementation, a user may retrieve channel information by touching preset keys on a remote controller. As a feasible implementation, the user may call channel information through voice. The embodiment merely describes several implementations of retrieving channel information by way of example, and the implementations of retrieving channel information in the process of practical application may be, but are not limited to, the above two implementations.

In this application, the first channel information is channel information corresponding to a channel received by the display device before the user makes an operation of calling the channel information.

The display will be described with reference to the accompanying drawings. Fig. 8 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 presented in the second area according to an embodiment. It can be seen that, in the initial state, the first area 83A shows the program broadcast by the channel 74, and the second area 84A shows the channel information of the channel 74, which can be referred to as the effect 81 in fig. 8. 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 instruction, the controller retrieves the channel information of the 75 channels, and controls the second area to display the channel information of the 75 channels, specifically, see the effect 82 in fig. 8, where the controller does not receive the audio/video data of the 75 channels.

In response to the confirmation operation of the user, the controller is configured to execute step S54 to decode the audio/video data of the target channel, resulting in the second program; the target channel is a channel corresponding to the channel information after switching;

S55, controlling the content displayed in the first area to be switched from a first program to a second program, where the first program is the program displayed in the first area before the user performs the channel switching operation.

The display device shown in this embodiment replaces frequent decoding switching of audio and video data by data and presentation channel information, and can replace conventional channel switching and re-decoding switching by data switching in the technology.

The display device shown in the embodiment changes the original channel switching mode, solves the problem of the original channel switching mode from a new angle, and has more innovativeness and practicability compared with the original mode.

The display device shown in this embodiment changes the channel switching mode of the inherent television, and uses a more concise text (channel information) description to briefly describe the current playable program form, so that the visual impact brought to the user by channel switching can be indirectly avoided, and the channel program which the user really wants to switch is captured by the mode, which is closer to the user experience mode.

The embodiment further provides a rendering method for a second region, which specifically may refer to fig. 9, as a feasible implementation manner, where the second region includes N display columns, where N is a positive integer; the controller is further configured to perform steps S91-S94:

s91, responding to the operation of calling channel information by the user, acquiring first program information and second program information;

s92 arranging the first program information and the second program information in order of playing time;

in this embodiment, each piece of program information (including the first program information and the second program information) corresponds to one playing time. The controller may sort the program information by play time.

S93, in response to the operation of calling channel information by the user, rendering the first N program information by taking the first program information as a starting point;

s94 controls each presentation bar to present one rendered program information.

In this embodiment, the controller implements a list move effect using CSS animation effects by creating a virtual list structure for recording program information. The virtual list display technology can render ten thousand or more data volumes, and because N data (N is far less than the number of program information) are rendered in each rendering, no extra burden rendering burden is brought to the display device.

As a feasible implementation, the controller is further configured to execute steps S95 to S96:

in response to the information switching operation by the user, S95 renders the first N program information starting from the switched program information;

and S96, controlling each display column to display the rendered program information.

Fig. 10 is a schematic diagram of a second area according to a possible embodiment, and it can be seen that the second area includes 4 display columns, in an initial state, a display effect of the second area can refer to an effect 101, and the second area displays program information 1, program information 2, program information 3, and program information 4. In response to the information switching operation of the user, the switched program information is program information 2, and at this time, the controller only renders program information 2, program information 3, program information 4, and program information 5, and at this time, the display effect of the second area may refer to the effect 102.

As a feasible implementation manner, the display device further includes a remote controller, where the remote controller is configured with a switch key, and in response to the touch of the switch key by the user, the second area switches the displayed channel information, and the controller is further configured to S111 to S112:

s111, responding to the user touch switching key, and counting the time of the user touch switching key to obtain touch time;

the embodiment does not limit the switch key, for example, in some feasible embodiments, the switch key may be an up key, and in some feasible embodiments, the switch key may be a down key.

In this embodiment, the touch time is determined by taking a time when the user touches the switch key as a starting point and a time when the user stops touching the switch key as an ending point.

And S112, controlling the second area to switch the displayed channel information according to the touch time.

To explain the above process with reference to the specific example, in a possible embodiment, the display device may receive 20 channels, and the second area jumps by one channel information every time the touch time increases by 0.2 s. For example, the following steps are carried out: the current second area shows the channel information of the channel 1, and when the touch time of the user touching the switch key is (0.2 × 20), the second area shows the channel information of the channel 20. According to the scheme shown in the embodiment, a user can quickly reach the end of a program by pressing the switching key for only one time, and clicks the ENTER key to switch the program.

As a feasible implementation manner, the display device further includes a remote controller, where the remote controller is configured with a switch key, and in response to the touch of the switch key by the user, the second area switches the displayed channel information, and the controller is further configured to S121 to S122:

s121, responding to the user touch switching key, and counting the time of the user touch switching key to obtain touch time;

and S122, if the touch time is more than or equal to the preset time, controlling the second area to switch the channel information.

The above process is described with reference to the specific example, and the preset time is not limited in this embodiment, for example, in some feasible embodiments, the preset time may be 0.2 s. When the time for the user to touch the switching key reaches 0.2s, the second area switches the channel information. For example, the following steps are carried out: the current second area shows the channel information of the channel 1, when the user touches the switch key for 0.2s, the second area shows the channel information of the channel 2, and when the user touches the switch key for 0.4s (reaching 0.2 for the second time), the second area shows the channel information … … of the channel 3 by analogy until the user terminates the touch switch key.
