Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The present application is mainly directed to a sound and picture synchronization process of a display device having a dual-system and dual-display structure, that is, a display device having a first controller (a first hardware system), a second controller (a second hardware system), a first display, and a second display, and the following first describes details of structures, functions, implementation manners, and the like of the display device having the dual-system hardware structure.

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 a source code, data received by the camera cannot be presented on a display 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.

As an embodiment, the camera adopted in the present application may have 1600 ten thousand pixels, so as to achieve the purpose of ultra high definition display. In actual use, cameras higher or lower than 1600 thousand pixels may also be used.

After the camera is installed on the display device, the contents displayed by different application scenes of the display device can be fused in various different modes, so that the function which cannot be realized by the traditional display device is achieved.

Illustratively, a user may conduct a video chat with at least one other user while watching a video program. The presentation of the video program may be as a background frame over which a window for video chat is displayed. Pictorially, this function may be referred to as "chat while looking".

Optionally, in the scene of "chat while watching", at least one video chat is performed across the terminals while watching the live video or the network video.

In another example, a user can conduct a video chat with at least one other user while entering the educational application for learning.

Accordingly, the first controller may receive a voice command input by a user through the first input interface, and the second controller may receive a voice command input by a user through the second interface.

The first control may also be responsive to a communication function initiated by a user via a remote control. For example, if the user wants to chat, the first controller presses a corresponding key on the remote controller, and at this time, the remote controller sends a chat start signal to the first controller. The first controller may receive a voice instruction input by a user through the first interface.

Generally, when a user falls asleep, the first display needs to be turned off to create a comfortable sleep environment for the user. Based on the application scenario, the technical solution shown in the embodiment of the present application may close the first display through interaction between the user and the first controller.

The specific interaction process comprises the following steps: when the first controller establishes contact with the user, the first controller receives a voice command. The voice command may be a control command of the display device during the actual application. For example: changing channels, adjusting sound and other control commands. The result of the parsing may also be the first instruction. In the technical scheme shown in the embodiment of the application, in order to improve the universality of the display device, the first instruction corresponds to a plurality of voice instructions. For example, the following steps are carried out: when the first controller receives a voice command of turning off the television, the analyzed voice command is the first command. When the first controller receives a voice command of closing the main screen, the analyzed voice command is the first command. When the first controller receives a voice command of opening the auxiliary screen, the analyzed voice command is the first command. When the first controller receives a voice command of 'entering a sound box mode', the analyzed voice command is a first command. And when the first controller 3 analyzes the first instruction, controlling the first display to be closed.

Optionally, in response to the parsing result being a first instruction, the first controller is further configured to send the parsing result to the second controller, where the parsing result is data related to the voice assistant: sound waves of voice commands and text of voice commands.

The preset interface is set by a user, and can be a clock display or a weather where the equipment is located. FIG. 12 is a diagram illustrating a default display interface in accordance with a preferred embodiment.

The operation of the display device will be described in detail with reference to specific examples. In one possible embodiment, the user outputs the voice command "play song" when the first control of the display device establishes contact with the user. The first controller sends sound wave related data of the voice command to the second controller in real time. The second controller outputs the data related to the sound wave to the second display, and the display interface of the second display can refer to fig. 13. The first controller analyzes the voice command while transmitting sound wave related data of the voice command, then sends characters of the analyzed voice command to the second controller, the second controller outputs the characters of the voice command to the second display, at this time, a display interface of the second display can refer to fig. 14, a first window 41 in fig. 14 displays sound waves for controlling voice, and a second window 42 displays the characters of the voice command.

In the application, the display content of the first window can play a role in prompting a client, and particularly, if the first window displays a corresponding sound wave interface, the first controller is proved to be successfully associated with a user. If the first window does not display the corresponding sound interface, it is proved that the first controller does not establish contact with the user. At this point, the user is prompted that the user is not in contact with the first controller at this point.

When the display device is in the speaker mode, the display device can still interact with the user through the first controller. The specific interactive process is as follows: the first controller receives a voice instruction input by a user through a first input interface, responds to the fact that the voice instruction is a second instruction, and sends the second instruction to the server so that the server issues query information data matched with the second instruction. The technical scheme shown in the embodiment of the application relates to two second instructions, wherein one instruction is an information content query instruction, and is also called as a second instruction; the other is an image content query instruction, also referred to as a third instruction. The control procedure of the second instruction and the third instruction is described below with reference to specific examples.

In a possible embodiment the display device is in a speaker mode. When the first controller of the display device establishes contact with the user, the first controller takes the received voice command as a third command. In the practical application process, the third instruction may be an image content query instruction, for example: a drama command, a movie command, and an animation command. For example, the following steps are carried out: when the first controller receives a voice command of 'playing a movie of XXX', the analyzed command is a third command; when the first controller receives a voice instruction of 'playing a TV play of XXX', the analyzed instruction is a third instruction; when the first controller receives a voice command of playing the cartoon of XXX, the analyzed command is a third command.

In the actual application process, the user instruction may be a second instruction, for example: weather forecast instructions, music instructions, news instructions. For example, the following steps are carried out: when the first controller receives a voice command of playing Qingdao weather, the command analyzed is a second command; when the first controller receives a voice instruction of 'playing song XXX', the analyzed instruction is a second instruction.

In the technical solution shown in the embodiment of the present application, the first controller correspondingly uses different processing manners for the third instruction and the second instruction. Two processing methods will be described below.
