Since the functions of the operating system 3911 of the a chip and the operating system 2911 of the N chip are similar, the relevant parts only need to be referred to the operating system 2911, and the description thereof will be omitted.

As shown in fig. 6b, the application layer of the display device contains various applications that may be executed on the display device 200.

Live television applications can provide live television through different signal sources. For example, a live television application may provide television signals using inputs from cable television, radio broadcast, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

Video on demand applications may provide video from different storage sources. Unlike live television applications, video-on-demand provides video displays from some storage sources. For example, video-on-demand may come from the server side of cloud storage, from a local hard disk storage containing stored video programs.

The media center application may provide various applications for playing multimedia content. For example, a media center may be a different service than live television or video on demand, and a user may access various images or audio through a media center application.

An application center may be provided to store various applications. The application may be a game, an application, or some other application associated with a computer system or other device but operable on a display device. The application center may obtain these applications from different sources, store them in local storage, and then be run on the display device 200.

In some embodiments, an operating system includes a kernel, a database, a framework layer, and an application layer, all of which are applications in the application layer.

And a selector in the user interface indicating that an item is selected, the position of the selector being movable by user input to change selection of a different item.

It should be noted that the multiple view display areas may present different levels of display images. For example, the first view display region may present video chat item content and the second view display region may present application layer item content (e.g., web page video, VOD presentation, application screen, etc.).

Optionally, the presentation of different view display areas has priority difference, and the display priorities of the view display areas are different among the view display areas with different priorities. If the priority of the system layer is higher than that of the application layer, when the user uses the acquisition selector and the picture switching in the application layer, the picture display of the view display area of the system layer is not blocked; and when the size and the position of the view display area of the application layer are changed according to the selection of the user, the size and the position of the view display area of the system layer are not affected.

The same level of display may be presented, in which case the selector may switch between the first view display region and the second view display region, and the size and position of the second view display region may change as the size and position of the first view display region changes.

Since separate operating systems may be installed in the a chip and the N chip, there are two independent but interrelated subsystems in the display device 200. For example, android (Android) and various types of APP can be independently installed on the chip A and the chip N, so that each chip can realize a certain function, and the chip A and the chip N can cooperatively realize a certain function.

In some embodiments, the display device includes a group home talk function and a hi talk function, the steps further including: the display equipment receives the push message, and judges whether the push message corresponds to a small-focus home or not according to the identification of the small-focus home function; if yes, the display device judges whether the television account number and the television ID carried in the push message are consistent with the account number and the device ID which are currently logged in by the device, and if not, a call is established according to the hi call flow. In the call, the call connection is established after the user operation of the terminal and the reality are selected. The function of small-focus at home can directly establish call connection without displaying the operation of the terminal user. Of these, the small group is two functions of one application software package at home (application a) and hi (application B).

The display device judges whether the television account number and the television ID carried in the push message are consistent with the currently logged-in account number and the device ID of the device: if not, ignoring, if so, performing sending an authentication request to the server.

and canceling the local window and the first window displayed by the video layer in response to the operation of switching the small windows input by the user, and creating a second window and a third window on the suspension layer, wherein the second window is used for playing the video data acquired by the camera by the user, and the third window is used for playing the video data sent by the mobile terminal.

In some embodiments, a display device includes: a microphone; a speaker; a camera;

the display is used for displaying an opposite-end window and/or a local window, wherein the opposite-end window is a window used for playing image data sent by the mobile terminal, and the local window is a window used for playing the image data acquired by the camera;

A processor for:

receiving a push message sent by a server, wherein the push message is sent by the server after receiving a video call request sent by the mobile terminal;

when the mobile terminal is authorized by the display device, responding to the push message, controlling a display of an opposite-end window on a display to not display a local window, controlling the loudspeaker to output audio data sent by the mobile terminal, controlling the camera to acquire image data for sending to the mobile terminal, and controlling the microphone to acquire audio data for sending to the mobile terminal;
