Description

Pattern display method

The present invention relates to a display method, in particular to a method for displaying patterns related to television programs.

Television programs are broadcast by television stations and produced by television stations, production companies, professional media or certain organizations. The types of television programs include news, drama, opera, music, drama, movie, entertainment, sports, variety shows, and social education. In the past, when users watched programs broadcasted by television, they usually learned the name of the program being broadcasted on the next channel through the text message displayed on the TV screen when switching channels. It was difficult to know the type of program. If the user wanted to watch a sports game, but the channel he switched to was broadcasting sports-related news, he would be at a loss. Therefore, if a method can be proposed to display the type of the current program in real time, it will help users to know the relevant information of the current program more clearly.

Therefore, the purpose of the present invention is to provide a pattern display method that can automatically display the channel information of a television program.

Therefore, the present invention discloses a pattern display method, which is implemented by a display device to display a pattern at least according to channel data related to a television program. The display device includes a display, a demultiplexer, a memory, and a processor electrically connected to the display, the demultiplexer and the memory. The display is used to display a video related to the television program. The memory stores at least a first lookup table, which includes a plurality of different program types and a plurality of program type patterns corresponding thereto. The pattern display method includes step (A), step (B), step (C), step (D), and step (E).

The step (A) is that when the demultiplexer receives the channel data, it performs demultiplexing according to the channel data to obtain a program-specific information and a plurality of information tables of service information corresponding to the program-specific information, and obtains the video and an audio related to the television program according to the program-specific information, and transmits the information tables to the processor.

The step (B) is that the processor obtains a target information table related to the program type to which the television program belongs based on the information tables.

The step (C) is that the processor decodes the target information table to obtain a target program type to which the TV program belongs.

The step (D) is that the processor obtains a target program type pattern corresponding to the target program type at least according to the target program type and the first lookup table, so as to output the target program type pattern as the pattern.

The step (E) is that the processor outputs the pattern and superimposes it on the video played by the display, so that the target program type pattern is displayed when the video is played by the display.

The effect of the present invention is that the demultiplexer demultiplexes the received channel data to obtain the information tables, the processor obtains the target information table and decodes it to obtain the target program type, and the corresponding target program type pattern is output as the pattern for superimposed display, so as to achieve the effect of automatically displaying the program type.

The first lookup table includes a plurality of different program types and their corresponding program type patterns, the second lookup table includes a plurality of group hearts and their corresponding expression patterns, the group hearts correspond to a plurality of voice feature clusters of a plurality of different voice category tones, and the event information table is related to the program type to which the television program belongs. The program types can be news, drama, opera, music, drama, movie, entertainment, sports, variety show, and social education, but are not limited thereto.

In this embodiment, the display device 1 is implemented as, for example, a television, a tablet computer, a notebook computer, a smart phone or a personal computer, but is not limited thereto.

The following describes an embodiment of the pattern display method of the present invention, including a group center generation process and a pattern marking process.

Referring to Figures 1 and 2, the group center generation process illustrates how to generate multiple group centers and includes the following steps.

In step 51, for each training audio file, the processor 16 performs a voice conversion on the training audio file to obtain a training feature vector.

In step 52, the processor 16 uses a clustering algorithm to divide the training feature vectors into a plurality of speech feature clusters, and stores the cluster center of each speech feature cluster in the second lookup table of the memory 13. The speech feature clusters are respectively a happy speech feature cluster, an angry speech feature cluster, a sad speech feature cluster, and a joy speech feature cluster, but not limited thereto; the clustering algorithm may be a k-means algorithm or a k-nearest neighbor algorithm, but not limited thereto.

Referring to Figures 1 and 3, the pattern marking procedure illustrates how to obtain a target program type pattern and a target expression pattern and output them for display, and includes the following steps.

In step 61, when the demultiplexer 11 receives the channel data, it performs demultiplexing according to the channel data to obtain the program-specific information and a plurality of information tables of the service information corresponding to the program-specific information, and obtains the video and an audio related to the television program according to the program-specific information, and transmits the information tables and the audio to the processor 16. Each information table corresponds to an identification code, and the program-specific information includes a program association table (PAT) related to the TV program, a program map table (PMT) related to the video and the audio of the TV program, a network information table (NIT) related to the frequency and modulation method of receiving the channel data, and a conditional access table (CAT) related to the encryption and decryption of the TV program. The service information includes a network information table of the program-specific information, a service information table (SDT) used to describe the name of the service in the system and the service provider, and an event information table (EIT) related to the name, start time, duration and running status of the TV program. Since the feature of the present invention does not lie in the detailed operation of demultiplexing the channel data known to those skilled in the art, their details are omitted here for the sake of brevity.

In step 62, the processor 16 obtains a speech feature vector based on the audio. The processor 16 performs speech conversion on the audio to obtain the speech feature vector. The audio includes multiple speech audios corresponding to one of the characters.

In step 63, the processor 16 obtains the target group heart according to the voice feature vector and the group hearts in the second lookup table. In this way, the corresponding situation (happy, angry, sad, or joyful) can be obtained according to the voice audio currently being played.

Referring to Figures 1 and 4, it is worth noting that step 63 includes the following sub-steps.

In step 631, the processor 16 calculates the distance between the speech feature vector and each center of the second lookup table to obtain multiple center of the group distances.

In step 632, the processor 16 uses the group center corresponding to the one with the shortest group center distance among the group center distances as the target group center.

In step 64, the processor 16 obtains a target information table related to the television program (i.e., an event information table related to the television program) corresponding to an identification code identical to the target identification code from the information tables according to the target identification code.

In step 65, the processor 16 decodes the target information table related to the television program to obtain a target program type to which the television program belongs. In this way, the corresponding program type (news, drama, opera, music, series, movie, entertainment, sports, variety show, or social education) can be obtained according to the video currently being played.

In step 66, the processor 16 obtains the target expression pattern corresponding to the target group center according to the target group center and the second lookup table, and obtains the target program type pattern corresponding to the target program type according to the target program type and the first lookup table, so as to output the target expression pattern and the target program type pattern as the pattern.

In step 67, the processor 16 outputs the pattern and overlays it on the video played by the display 12, so that the target expression pattern and the target program type pattern are displayed when the video is played by the display 12. In this way, the program type pattern and the situation pattern of the currently played program can be displayed on the display 12 for the user to better integrate into the TV program.

It is worth mentioning that in another embodiment, the order of steps 62-63 and steps 64-65 of the pattern marking procedure can be swapped or performed simultaneously, and is not limited thereto. In other words, the order of the method for obtaining the target group heart (steps 62-63) and the method for obtaining the target program type (steps 64-65) is not limited, and steps 64-65 can be performed first to obtain the target program type, and then steps 62-63 can be performed to obtain the target group heart, or steps 62-63 and steps 64-65 can be performed simultaneously to obtain the target group heart and the target program type.

In summary, the pattern display method of the present invention uses the processor 16 to group the voice feature clusters to obtain the group centers, and the demultiplexer 11 demultiplexes the channel data to obtain the information tables. The processor 16 obtains the audio according to the information tables, and performs the voice conversion on the audio to obtain the voice feature vector, and obtains the target group center according to the voice feature vector and the second lookup table. In this way, the corresponding situation can be obtained according to the audio currently being played. In addition, the processor 16 The target information table is obtained from the information tables, and the target information table is decoded to obtain the target program type, so that the corresponding program type can be obtained according to the video currently being played, and then the target expression pattern corresponding to the target group and the target program type pattern corresponding to the target program type are output as the pattern and superimposed and displayed, thereby displaying the situation and program type related to the TV program on the display 12 for the user to better integrate into the TV program, so that the purpose of the present invention can be achieved.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
