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.

For example, the display device 200 is controlled using an application program running on the smart device. The application may provide various controls to the User through an intuitive User Interface (UI) on a screen associated with the smart device.

For example, the mobile terminal 100B and the display device 200 may each have a software application installed thereon, so that connection communication between the two can be realized through a network communication protocol, and the purpose of one-to-one control operation and data communication can be further realized. Such as: a control instruction protocol can be established between the mobile terminal 100B and the display device 200, a remote control keyboard is synchronized to the mobile terminal 100B, and the function of controlling the display device 200 is realized by controlling a user interface on the mobile terminal 100B; the audio and video content displayed on the mobile terminal 100B may also be transmitted to the display device 200, so as to implement a synchronous display function.

As shown in fig. 1, the display apparatus 200 may also perform data communication with the server 300 through various communication means. In various embodiments of the present application, the display device 200 may be allowed to be in a wired or wireless communication connection with the server 300 via a local area network, a wireless local area network, or other network. The server 300 may provide various contents and interactions to the display apparatus 200.

Illustratively, the display device 200 receives software Program updates, or accesses a remotely stored digital media library by sending and receiving information, and Electronic Program Guide (EPG) interactions. The servers 300 may be a group or groups, and may be one or more types of servers.

In addition, the first display 201 displays the multi-party interactive picture while displaying the traditional television program picture, and the multi-party interactive picture does not block the traditional television program picture. The display mode of the traditional television program picture and the multi-party interactive picture is not limited by the application. For example, the position and the size of the traditional television program picture and the multi-party interactive picture can be set according to the priority of the traditional television program picture and the multi-party interactive picture.

Taking the example that the priority of the traditional television program picture is higher than that of the multi-party interactive picture, the area of the traditional television program picture is larger than that of the multi-party interactive picture, and the multi-party interactive picture can be positioned at one side of the traditional television program picture and can also be arranged at one corner of the multi-party interactive picture in a floating manner.

The display device 200 may be, for example, a liquid crystal display, an oled (organic Light Emitting diode) display, or a projection display device; on the other hand, the display device can be a display system consisting of an intelligent television or a display and a set-top box. The specific display device type, size, resolution, etc. are not limiting, and those skilled in the art will appreciate that the display device 200 may be modified in performance and configuration as desired.

The display apparatus 200 may additionally provide an intelligent network tv function that provides a computer support function in addition to the broadcast receiving tv function.

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 ten 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. The function is called 'chat while watching'.

Optionally, in a scene of "chat while watching", at least one video chat is performed across terminals while watching a live video or a 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. For example, a student may interact remotely with a teacher while learning content in an educational application. Vividly, this function can be called "chatting while learning".

In another example, a user conducts a video chat with a player entering a card game while playing the game. For example, a player may enable remote interaction with other players when entering a gaming application to participate in a game. Figuratively, this function may be referred to as "watch while playing".

Optionally, the game scene is fused with the video picture, the portrait in the video picture is scratched and displayed in the game picture, and the user experience is improved.

Optionally, in the motion sensing game (such as ball hitting, boxing, running and dancing), the human posture and motion, limb detection and tracking and human skeleton key point data detection are obtained through the camera, and then the human posture and motion, the limb detection and tracking and the human skeleton key point data detection are fused with the animation in the game, so that the game of scenes such as sports and dancing is realized.

In another example, a user may interact with at least one other user in a karaoke application in video and voice. Vividly, this function can be called "sing while watching". Optionally, when at least one user enters the application in a chat scenario, multiple users may jointly complete recording of a song.

In another example, a user may turn on a camera locally to take pictures and videos, figurative, which may be referred to as "looking into the mirror".

In other examples, more or less functionality may be added. The function of the display device is not particularly limited in the present application.

The first controller is configured to perform step S102 to transmit the received user voice to the server.

In some feasible embodiments, the first controller may be connected with the server through a wireless module, and the corresponding user voice may be transmitted to the server through a network channel. In some embodiments, the first controller may be connected to the server via a wire, and the corresponding user voice may be transmitted to the server via a physical channel.

The server is configured to execute step S103 to process the user voice to obtain a headword;

the user's speech may be processed using natural language processing techniques that are conventional in the art. For example, the server segments the user's voice "i want to see liu de hua movie" into a set of words that includes: "I", "want", "see", "Liudebua", "of", "movie". The server deletes some unrealistic words "i", "want", "see", "what" in the word set. The server finally obtains the central word including: "movies" and "Liudebhua".

The present embodiment is only an exemplary processing method of the user voice, and the processing method of the user voice in the process of practical application may be, but is not limited to, the above processing method.

The server is configured to execute step S104 to call the query tag, and output the central word and the query tag; the query tag is a tag corresponding to the central word and is used for prompting the user to output related user voice;

according to the technical scheme, a headword list is constructed in advance and used for accessing headwords and labels corresponding to the headwords.

For example, table 1 is a list of core words shown according to one possible embodiment.

TABLE 1

The present application relates to information tagged to provide suggestive action on a user's search. For example, for Liu De Hua, one identity that the director can use to prompt the user for Liu De Hua is the director, prompting the user to search for movies that the Liu De Hua has directed. As another example, "Meng Mei Qin" may be a label for "clique" that prompts the user to search for Meng Mei Qin, etc.

The second controller is configured to perform step S105 to control the second display to show the headword and the query tag.

When the second display shows the core word and the query tag, the user can make further searches according to the prompt of the core word and the query tag.

As can be seen from the above technical solutions, the present embodiment shows a display system, including: the display device comprises a server and a display device, wherein the display device is provided with a first controller and a second controller. When the media assets need to be searched, the user outputs the user voice to the first controller. The first controller transmits the received user voice to the server. The server processes the voice of the user to obtain a central word; calling a query tag, wherein the query tag is used for prompting a user to output related user voice; and outputting the central word and the query tag to a second controller. And the second controller controls the second display to display the central word and the query tag. It can be seen that the display system shown in the embodiment of the present application obtains the core word and the query tag related to the core word by processing the user voice, and further displays the core word and the query tag on the second display. The user can carry out targeted media asset search aiming at the content displayed on the second display, and the user experience is good.

The embodiments shown in the present application will be further described with reference to specific examples.

In a possible embodiment, the user speech output by the user is "movie of liu de hua", and in this case, the display device is shown with reference to the interface 11 in fig. 12, and it can be seen from the interface 11 that the second display shows the user speech in the form of text. The first controller sends "movie of Liudebua" to the server. The server processes the "movie in Liu De Hua" to obtain the core words "Liu De Hua" and "movie". The server calls the query tags 'actor', 'singer' and 'director' corresponding to 'Liu De Hua'; the query tag corresponding to "movie" is: "comedy", "gunfight", "love" and "ethics". And the server sends the central word and the query tag to the second controller. The second controller controls the second display to display the above-mentioned keyword and the query tag, and at this time, the interface displayed by the display device can refer to the interface 21 in fig. 12. The user may perform a targeted media search for the content presented on the second display, for example, the user input user speech may be "liu de director's comedy movie", "liu de director's gunfight movie", or the like.

FIG. 12 is a schematic diagram illustrating, by way of example only, one interface presented by the display device during a search. In the process of practical application, the display positions of the central words or the query tags can be configured according to requirements. For example, FIG. 13 is a schematic diagram illustrating an interface presented by the second display, according to one possible embodiment; as can be seen from fig. 13, the first display is used to display the central word in the upper half of the second display and the query tag in the lower half of the second display.

In some feasible embodiments, the second controller may also generate some prompts based on the received keywords and the query tags, and control the second display to display the keywords, the query tags and the prompts. Specifically, referring to fig. 14, it can be seen from fig. 14 that the second display simultaneously displays the core word, the query tag and the prompt.

It should be noted that the embodiments of the present application are merely exemplary to show several ways of displaying the core word and the query tag, and in the practical application process, the ways of displaying the core word and the query tag may be, but are not limited to, the above several ways, and the applicant herein does not make much limitation.

In order to obtain a headword with a higher speech fitting degree with a user, the embodiment of the present application is further improved on the basis of the display system shown in the foregoing embodiment, and referring to fig. 15, an interaction flowchart of the display device and the server after improvement, fig. 15 is an interaction flowchart of the display device and the server shown according to a feasible embodiment; as can be seen in fig. 15:

the first controller is configured to perform step S101 of receiving a user voice;

the implementation manner of receiving the user voice may refer to the above embodiments, and the applicant herein does not describe any more;

the first controller is configured to perform step S102 to transmit the received user voice to the server;

the implementation manner of receiving the user voice may refer to the above embodiments, and the applicant herein does not describe any more;

the server is configured to execute step S1031 to train the user speech to get keywords;

the training of the user's speech may be performed by natural language processing techniques that are conventional in the art, such as removing some meaningless symbols or text from the user's speech to obtain keywords.

In some feasible embodiments, domain tags may be configured for the keywords for subsequent use. Specifically, the server configures the domain label for the keyword by performing steps (11) - (13).

Step (11) searching a query field in a pre-stored hotspot statistical table, wherein the query field is a field to which the keyword belongs;

the hotspot statistical table is generated by determining the concerned hotspots of the user in the latest period of time by using a deep learning textCNN model. The specific process comprises the steps (111) to (116)

Step (111) collecting the search data of the user in the recent period of time;

the search data may be a user voice of the user, or a play record of the user, or the like.

For example, the user's last month search data can be found in table 2.

TABLE 2

Matters and matters	Content providing method and apparatus	Matters and matters	Content providing method and apparatus
				User speech	Liudebua movie	Playing film	Ten faces buried in the abdomen
User speech	Liu De Hua sung song	Playing film	Miss peach
				User speech	Movie of Liudebhua director	Playing film	Slimming male and female
User speech	Comedy that Liu De Hua director has performed	Playing film	(Wu Zhong dao)
				……	……	……	……

Step (112) then carries out word segmentation processing on the search data, and removes some meaningless symbols or texts to obtain word segmentation.

For example, the participles obtained by the participle processing of "Liu Dehua movie" are "Liu Dehua" and "movie", respectively;

for example, the participles obtained by the participle processing of the "songs sung in Liu De Hua" are respectively "Liu De Hua" and "songs";

for example, the participles obtained by the participle processing of "liu de hua director comedy" are "liu de hua", "director" and "comedy" … … respectively;

other word segmentation processing modes can be adopted in the practical application process, and the applicant does not make much limitation.

Step (113) then mapping each participle into a multi-dimensional word vector in an embedding mode such as word2vec or GLOV, and the like, and digitizing the natural language;

continuing with the embodiment shown in table 2, the word vector corresponding to the participle liudebua is: "movie", "song", "director", "comedy"; the word vectors corresponding to the word segmentation movies are as follows: liu Dehua, director, comedy, Ten-face buried and Miss peach … ….

Step (114), after the word vectors are constructed, splicing all the word vectors into a two-dimensional vector;

wherein, the two-dimensional vector is a participle and a field corresponding to the participle, and the table 3 is a table for recording the two-dimensional vector;

TABLE 3

Step (115) inputting the training data into a textCNN model for training, obtaining a vector after convolution of three convolutional layers and max-pool, wherein the vector represents certain characteristics (also called as labels in the application) of each convolutional layer in terms of training data;

and (116) finally, inputting the vector into a single-layer neural network and classifying the vector by softmax to obtain a final domain classification result, namely a film and television class.

Wherein, the two-dimensional vector is the field corresponding to the participle and the participle, and the table 4 is used for recording the table of the two-dimensional vector;

TABLE 4

For example, a word vector corresponding to "movie" may be: "thriller", "gunfight", "love" … …; the word vector corresponding to the animation may be: "education", "national school", "thank" … …; the word vector corresponding to the animation may be: "year", "history", "love" … …; then the corresponding label in the movie and television field can be: education, national education, thanksgiving, thrilling, gunfight, love, era and history.

Based on the method, each field is bound with the corresponding label, and then the bound result is stored in the hot spot statistical table.

When receiving user voice, the server searches a pre-stored hotspot statistical table for a query field;

calling a field label, wherein the field label is a label corresponding to the query field;

and (13) binding the domain label with the keyword.

For example, for the keyword "movie", the domain is the "movie" domain, and the corresponding domain labels are "education", "national science", "thank", thriller "," gun battle "," love "," year "," history "… …;

since the second display has limited display space, in a feasible embodiment, the number of occurrences of each tag can be statistically counted, and then the tags can be sorted in descending order of the number of occurrences of the last month as shown in table 5.

TABLE 5

Setting N to 3, the keyword "movie" is bound to the domain tags "comedy", "gunfight", and "love" in this embodiment.

In the actual application process, if the keyword pairs use multiple fields, in this embodiment, the query relevance may be arranged in the order from large to small, and the query relevance is the relevance between the keyword and the query field; the first N keywords are retained.

By way of example, the corresponding areas for "Liudebua" may be: "movie", "singer", "actor", "director"; the server can calculate the relevancy of "Liu De Hua" and "movie & TV", "singer", "actor" and "director", and the calculated result can be referred to table 6;

TABLE 6

Serial number	Keyword	FIELD	Degree of correlation
				1	Liu De Hua	Film and television	80％
2	Liu De Hua	Actor(s)	65％
				3	Liu De Hua	Singer		32％
4	Liu De Hua	Director							31％

If the set N is 1, the corresponding field of "Liu Dehua" is "movie and television"; if N is set to 2, the fields corresponding to "liu de hua" are "movie" and "actor".

In the process of practical application, if the keyword pairs are in multiple fields, the display space of the second display is limited, so that in this embodiment, the business proportion can be arranged in the descending order, and is the ratio of the number of times of occurrence of the query field to the number of times of occurrence of all the fields;

by way of example, the corresponding areas for "Liudebua" may be: "movie", "singer", "actor", "director"; the server can calculate the relevancy of "liu de hua" to "movie & TV", "singer", "actor" and "director", and the calculated results can be referred to table 7.

TABLE 7

Serial number	Keyword	FIELD	Service proportion
				1	Liu De Hua	Film and television	37％
2	Liu De Hua	Actor(s)	26％
				3	Liu De Hua	Singer		12％
4	Liu De Hua	Director	3％

If the N is set to be 1, the corresponding field of the Liudebua is film and television; if N is set to 2, the fields corresponding to "liu de hua" are "movie" and "actor".

the second controller is configured to perform step S105 to control the second display to show the headword and the query tag.

In this embodiment, the server stores a headword list in advance, where the headword list is used to record a tag corresponding to each keyword. Table 8 shows a list of core words according to one possible embodiment;

TABLE 8

For example, in one possible embodiment, the user's input speech is "songs that are not likely to sing while the display device presents an interface that can be seen in interface 21 of FIG. 17. The keywords of the server after the voice training of the user are 'Maounease' and 'music'. The server calculates the similarity between the keyword 'Maouneasy' and the user voice 'Maouneasy song', and the obtained result is that the similarity is 80% (more than the preset similarity); the similarity of "music" to "a song that a horse hair is not likely to sing" of the user voice is found to be 75% (greater than a preset similarity). In this embodiment, the keyword is matched with the user voice. The server takes "mao not be easy" and "song" as the core words. The server calls a label corresponding to the Maouneasy and the song in the headword list as a query label, wherein the query label corresponding to the Maouneasy is a singer; the query tags for "songs" are "classical", "modern", "jazz". The server sends the query tag and the central word to a second controller, and the second controller controls a second display to display the query tag and the central word. The interface presented by the display device at this time can be referred to as interface 22 in fig. 17.

In one possible embodiment, the user's input of the user's voice is "Liuhua song" and the interface presented by the display device may refer to interface 31 in FIG. 18.

In this embodiment, the keyword "liu de hua" does not match the user's voice. The server screens out the Liu De Hua central words with the highest similarity to the Liu De Hua from the preset central word list. The server calls tags corresponding to "Liu De Hua" and "songs" in a preset keyword list to be query tags, wherein the query tags corresponding to "Liu De Hua" are "actors", "singers" and "directors"; the query tags for "songs" are "classical", "modern", "jazz". The server sends the query tag and the central word to a second controller, and the second controller controls a second display to display the query tag and the central word. The interface presented by the display device at this time can be seen in interface 32 of fig. 18.

In one possible embodiment, the user's input of the user's voice is "zhanghua song" and the interface presented by the display device may refer to interface 41 in fig. 19. The keywords after the server trains the user voice are 'zhanghua' and 'music'. Wherein, the field of the movie belongs to the movie, the corresponding field label of the movie is the movie, the TV play and the cartoon; the server calculates the similarity between the keyword 'zhangxihua' and the user voice 'zhanghua song', and the obtained result is that the similarity is 15% (less than the preset similarity); the similarity of "music" to the user's voice "zhanghua sung song" results in a similarity of 75% (greater than the preset similarity). In this embodiment, the keyword "zhangaihua" does not match the user's voice. The server will screen out the similar core words as "zhangxihua" in the core word list, but the core words similar to "zhangxihua" are not found in the preset core word list. The server sends the inquiry labels corresponding to the domain labels 'movie', 'TV play', 'animation' and 'song' corresponding to the 'zhangaihua' to the second controller, and the second controller controls the second display to display the inquiry labels and the central words. The interface presented by the display device at this time can be seen as interface 42 in fig. 19.
