Detailed Description

To make the objects, technical solutions and advantages of the exemplary embodiments of the present application clearer, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.

Furthermore, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resources, and usually only supports video decoding with a resolution of 4K at most, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resources (usually GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. CPU) in the hardware system to perform soft decoding on the video.

The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the problem of picture blocking or unsmooth flow can occur. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multi-channel video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.

In view of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).

The concept to which the present application relates will be first explained below with reference to the drawings. It should be noted that the following descriptions of the concepts are only for the purpose of facilitating understanding of the contents of the present application, and do not represent limitations on the scope of the present application.

Since the functions of theoperating system 3911 of the a chip are similar to those of theoperating system 2911 of the N chip, reference may be made to theoperating system 2911 for relevant points, and details are not repeated here.

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

The N-chip application layer 2912 may include, but is not limited to, one or more applications such as: a video-on-demand application, an application center, a game application, and the like. Theapplication layer 3912 of the a-chip may include, but is not limited to, one or more applications such as: live television applications, media center applications, and the like. It should be noted that what applications are respectively contained in the a chip and the N chip is determined according to an operating system and other designs, and the present invention does not need to make specific limitations and divisions on the applications contained in the a chip and the N chip.

The live television application program can provide live television through different signal sources. For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on thedisplay device 200.

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

The media center application program can provide various applications for playing multimedia contents. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

The application program center can provide and store various application programs.

A schematic diagram of a user interface in adisplay device 200 according to an exemplary embodiment is illustrated in fig. 7. As shown in fig. 7, the user interface includes a plurality of view display areas, illustratively, a firstview display area 201 and aplay screen 202, wherein the play screen includes a layout of one or more different items. And a selector in the user interface indicating that the item is selected, the position of the selector being movable by user input to change the selection of a different item.

It should be noted that the multiple view display areas may present display screens of different hierarchies. For example, a first view display area may present video chat project content and a second view display area may present application layer project content (e.g., web page video, VOD presentations, application screens, etc.).

Optionally, the different view display areas are presented with different priorities, 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 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 influenced.

The display frames of the same hierarchy can also be presented, at this time, the selector can switch between the first view display area and the second view display area, and when the size and the position of the first view display area are changed, the size and the position of the second view display area can be changed along with the change.

Since the a-chip and the N-chip may have independent operating systems installed therein, there are two independent but interrelated subsystems in thedisplay device 200. For example, Android (Android) and various APPs 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 cooperatively realize a certain function. Therefore, the screen interaction method provided by the embodiment is applied to display equipment, such as a television terminal, a large-screen intelligent terminal and the like, the display equipment at least comprises two systems, and the systems can communicate with each other.

An exemplary screen interaction method provided by the present embodiment will be described below with reference to the television terminal shown in fig. 8.

Referring to fig. 8, the television terminal provided in this embodiment includes an N system and an a system, and the N system and the a system perform screen interaction through an interprocess communication mechanism. In the television terminal, there are some differences in presettiness between the N system and the a system. In this embodiment, the N system is pre-configured as a Master system (i.e., a main system) of the television terminal, which includes but is not limited to an audio/video processing module and a picture processing module, and is mainly used for playing contents such as audio/video and pictures. The a system is pre-configured as a Transmit system (i.e., an auxiliary system) of a television terminal, which includes, but is not limited to, a voice processing module and a manipulation processing module, and is mainly used for processing contents of non-video-class applications.

According to the difference of data sources, the television terminal provided in this embodiment has two communication modes, one is a Local Area Network (LAN) interface, and the other is a Wide Area Network (WAN) interface. And mobile terminals such as mobile phones and tablet computers communicate with the television terminal by calling the two interfaces. The LAN interface is connected with the system A and mainly bears push logic in the LAN, and monitors the request of the data of the mobile terminal at any time after the LAN interface is defined. The WAN interface is connected with the N system and is mainly used for receiving the pushing logic of the wide area network, passively receiving the message pushed by the external equipment after being defined and monitoring the data request.

The main network module of the television terminal provided by the embodiment is arranged in the system a, and the auxiliary network module of the system N is bridged to the main network module of the system a. Since the television terminal is usually disposed indoors, it is usually in a local area network environment, for example, a WIFI (wireless local area network) environment. Therefore, the N system of the tv terminal usually communicates with the mobile terminal under the WAN through the WAN interface. The a system communicates with a mobile terminal under a local area network, typically through a LAN interface.

Based on the television terminal provided in this embodiment, this embodiment provides a screen interaction method for implementing media asset sharing and interaction control between the television terminal and the mobile terminal.

Referring to fig. 9, the present embodiment describes the screen interaction method provided by the present embodiment by taking N systems as an example, and the method specifically includes the following steps S901 to S904.

In step S901, the N system receives a service processing request from the mobile terminal.

The mobile terminal in this embodiment includes, but is not limited to, smart electronic devices such as a smart phone, a tablet computer, a notebook computer, a smart watch, and AR (Augmented Reality) glasses.

When the mobile terminal needs to display the resource information related in the local service on the screen of the television terminal or wants to control the television terminal, a service processing request needs to be sent to the television terminal. Since the services of the mobile terminal are usually based on independently operating APP (Application) or other mobile client operation carrier, for example, wechat public number. When the platform on which the mobile terminal depends is an independently operated APP, the mobile terminal can send a service processing request to the television terminal by calling a LAN interface or a WAN interface of the television terminal. When the mobile terminal is an operation carrier such as a WeChat public number and the like depending on a platform, the mobile terminal sends a service processing request to the television terminal by calling a WAN interface of the television terminal because the WeChat public number has the environmental advantage of a wide area network.

Because the N system is connected with the WAN interface, the service processing requests received by the N system are all from the WAN interface. And, after the N system receives the service processing request sent by the mobile terminal, the step S902 is directly executed.

Step S902, the N system determines the service type of the requested service according to the service processing request.

The service types of the television terminal include, but are not limited to, an audio/video service, a picture service, a voice service, a control service, and the like. For example, the audio/video service plays audio and video, the picture service includes displaying pictures, the voice service includes performing voice call with the television terminal, and the control service includes controlling the television terminal by the mobile terminal.

In a dual system television terminal, different types of services are handled since different systems are configured. For example, the N system is configured to handle video traffic, picture traffic, etc., and the a system is configured to handle voice traffic, control traffic, etc. Therefore, in this step, after the N system receives the service processing request, the service processing request needs to be parsed to determine the service type of the requested service, so that the corresponding system can process the service type.

It should be noted that the service types determined by the television terminal according to one service processing request may be only one, or may be two or more, and are specifically determined according to the content carried by the service processing request itself.

Step S903, if the service type of the N system is the specified service type of the current system, the requested service is processed.

The specified service type of the current system is a service type specified in the television terminal to be processed by the current system. For example, for an N system, the specified service types of the current system include audio video service, picture service, and the like.

And when the service type of the requested service is the specified service type of the current system, directly processing the requested service by the N system. Illustratively, when the N system receives a video screen projection request of the mobile terminal, the data of the projected video is directly acquired from the mobile terminal and played.

Step S904, if the service type of the N system is not the specified service type of the current system, instructing the a system to process the requested service.

And when the requested service analyzed by the N system is not the specified service type of the N system, the N system instructs the A system to process the requested service. For example, when the N system receives a voice control request, the content related to the voice control is transmitted to the a system, and the a system controls the television terminal.

Referring to fig. 10, the present embodiment describes the screen interaction method provided in the present embodiment by taking the system a as an example, and the method specifically includes the following steps S1001 to S1006.

Step S1001, the system A receives a service processing request of the mobile terminal.

Since the a system is connected to the LAN interface, the LAN interface can receive not only data from the LAN interface but also cross-network data from the WAN interface. That is, the service processing request received by the a system may come from the LAN interface or the WAN interface.

In step S1002, if the interface type is the designated interface type of the a system, the a system directly performs step S1004.

When the system a receives a service processing request from the mobile terminal, it needs to determine the interface type of the service processing request, so as to determine whether the data interface is a LAN interface or a WAN interface. If the interface type is a designated interface type (i.e., LAN interface) of the a-system, the a-system performs step S1004 in order to improve screen interaction efficiency.

Step S1003, if the interface types are different from the specified interface types of the system a, the system a sends the service processing request to the N system, so that the N system processes the service processing request.

For example, when the a system receives a service processing request from the WAN interface, the service processing request is sent to the N system to be processed by the N system. The N system processes the service processing request, including the above steps S901 to S904, which is not described herein in this embodiment.

Step S1004, the system a determines the service type of the requested service according to the service processing request.

In step S1005, if the service type is the specified service type of the a system, the a system processes the requested service.

For the a system, the specified traffic type includes voice traffic, control traffic, and the like. Illustratively, when the system A receives a voice control request sent by the mobile terminal, the system A can control the television terminal according to a control instruction request carried by the voice control.

Step S1006, if the service type is not the specified service type of the A system, the A system instructs the N system to process the requested service.

Illustratively, when the A system receives a video screen projection request of the mobile terminal, the related request content is sent to the N system, so that the N system controls the playing of the screen projection video.

By the screen interaction method provided by the embodiment, in the process of screen interaction between the dual-system or multi-system television terminal and the mobile terminal, when multiple types of services need to be processed at the same time, the television terminal can control each system to process the corresponding type of service, so that the screen interaction efficiency is improved.

Referring to fig. 11, a structural diagram of a screen interaction device provided in this embodiment is shown. The screen interaction device is applied to a display device provided with at least two systems, and each system comprises one screen interaction device. The screen interaction device comprises the following components.

Optionally, the screen interaction apparatus further includes a second determiningmodule 1104, configured to determine a service type of the requested service according to the service processing request if the interface type of the service processing request is a specified interface type of the current system. Or, if the interface type of the service processing request is not the specified interface type of the current system, the service processing request is sent to another system so as to be processed by the other system.

Optionally, the service types in this embodiment include an audio/video service, a picture service, a voice service, and a control service.

Optionally, the interface types in this embodiment include a wide area network interface and a local area network interface.

Through the screen interaction device provided by the embodiment, when the dual-system or multi-system television terminal is in the screen interaction process with the mobile terminal and when various types of services need to be processed at the same time, the television terminal can control each system to process the corresponding type of services, so that the screen interaction efficiency is improved.
