The power supply source may supply power to the display device 200 through power input from an external power source under the control of the controller 250.

In some embodiments, the display device 200 may receive a query instruction input by a user through the communicator 220. For example, when communicator 220 is a touch component, the touch component may together with display 260 form a touch screen. On the touch screen, a user can input different control instructions through touch operation, for example, the user can input touch instructions such as clicking, sliding, long pressing, double clicking and the like, and different touch instructions can represent different control functions.

To implement the different touch actions, the touch assembly may generate different electrical signals when the user inputs the different touch actions, and transmit the generated electrical signals to the controller 250. The controller 250 may perform feature extraction on the received electrical signal to determine a control function to be performed by the user based on the extracted features.

For example, when a user inputs a click touch action at a search location in the display interface, the touch component will sense the touch action to generate an electrical signal. After receiving the electrical signal, the controller 250 may determine the duration of the level corresponding to the touch action in the electrical signal, and recognize that the user inputs the click command when the duration is less than the preset time threshold. The controller 250 then extracts the location features generated by the electrical signals to determine the touch location. When the touch position is within the search position range, it is determined that the user has input a click touch instruction at the search position. Then, the controller 250 may start a media search function and receive a search instruction input by the user, such as a search keyword, a voice search instruction, etc.

In some embodiments, the user may trigger the query operation through a specific gesture operation on the touch screen, for example, when the user performs two continuous double-click operations on the display interface, the controller 250 may determine an interval time between two continuous double-clicks, and when the interval time is less than a preset time threshold, recognize that the user inputs the continuous double-click operation, and determine that the user triggers the media resource search operation.

In some embodiments, a user may enter voice instructions on a touch screen via a touch operation, such as a user may trigger a voice query operation on display 260 via a voice-triggered gesture.

In some embodiments, the communicator 220 may also be an external control component, such as a mouse, remote control, or the like, which may establish a communication connection with a display device. When the user performs different control operations on the external control component, the external control component may generate different control signals in response to the control operations of the user and transmit the generated control signals to the controller 250. The controller 250 may perform feature extraction on the received control signal to determine a control function to be performed by the user according to the extracted features.

For example, when a user clicks a left mouse button at any position in the channel display interface through the external control component, the external control component can sense a control action to generate a control signal. After receiving the control signal, the controller 250 may control the stay time of the action at the position according to the control signal, and identify that the click command is input by the user through the external control component when the stay time is less than the preset time threshold. The clicking instruction is used for triggering an input function instruction of the query instruction or switching the media resource page under the current scene.

For another example, when the user presses a voice key on the remote control, the remote control may initiate a voice entry function, and during the process of the user entering a voice command, the remote control may synchronize the voice command to the display 260, at which time the display 260 may display a voice entry identifier to indicate that the user is entering a voice command.

In some embodiments, the communicator 220 may also be a control component, such as a desktop computer, coupled to the display 260, which may be a keyboard coupled to the display. The user can input different control instructions, such as media information switching instructions, inquiry instructions and the like through the keyboard.

Illustratively, the user may input a click command, a voice command, etc. through the corresponding shortcut key.

Referring to fig. 5, a schematic diagram of an electronic program guide interface is shown.

In the user interface of the display device, television programs (e.g., past, current, and upcoming television programs) that are broadcast for each time period may be presented and displayed via an electronic program guide (Electronic Program Guide, EPG) interface. Wherein, the television programs broadcast in the past comprise programs recorded by users on the broadcast television programs. As shown in fig. 5, in the user interface 501 of the display device, the electronic program guide interface 502 displays a plurality of programs recorded by the user 2023 on 1 month and 10 days, including 4 channels from channel 1 to channel 4, and television programs respectively corresponding to time periods from 10:00 to 12:00.

With continued reference to fig. 5, in the user interface 501 of the display device, each program has a corresponding program field. In each program field, program information corresponding to each program may be displayed, where the program information may include: program name, program introduction, program duration, etc.

The process of generating the electronic program guide interface will be described below.

In some embodiments, referring to fig. 6, the controller may also perform the following method:

S610: and performing frequency locking processing and demodulation processing on the plurality of television program signals to obtain a plurality of second transport streams corresponding to the plurality of television program signals.

Reference is made to a schematic diagram of recording a television program as shown in fig. 7.

As shown in fig. 7, after receiving a television program signal (typically, a radio frequency signal) sent from a satellite or the ground, the display device may perform a frequency locking process on the television program signal through a Tuner in the display device, so as to obtain a frequency-locked television program signal (typically, an intermediate frequency signal). And then, the display equipment can demodulate the frequency-locked television program signal through a demultiplexer (Demodulator) to obtain a second transmission stream corresponding to the frequency-locked television program signal.

The second Transport Stream may refer to a Transport Stream (TS) or a Multi-program Transport Stream (Multi-program Transport Stream, MPTS). The second transport stream typically includes video streams, audio streams, program specific information (Program Specific Information, PSI), service information tables (Service Information, SI), and other data packets.

Therefore, through the flow, the frequency locking processing and the demodulation processing can be carried out on the plurality of television program signals, and a plurality of second transmission streams corresponding to the plurality of television program signals are obtained.

S620: and recording the plurality of second transport streams to obtain a plurality of first transport streams corresponding to the plurality of programs.

After the second transport stream is obtained, the display device may record the second transport stream by using a recorder, and store the recorded second transport stream (i.e., the first transport stream) into the memory.

The recorder may be an acquisition card integrated in the display device, or an external recording box connected with the display device, etc., which is not limited in this embodiment; the memory may be an external memory (e.g., a mechanical hard disk, a solid state hard disk, a USB flash disk, etc.) connected to the display device, or may be a cloud memory, which is not limited in this embodiment.

Therefore, through the flow, the plurality of second transport streams can be recorded, and a plurality of first transport streams corresponding to the plurality of programs are obtained.

S630: and analyzing a plurality of first transport streams corresponding to the plurality of programs to obtain service information SI corresponding to the plurality of programs.

It will be appreciated that the first transport stream also includes video streams, audio streams, program specific information (Program Specific Information, PSI), service information tables (Service Information, SI) and other data packets in the second transport stream corresponding thereto. The program specific information PSI is a description of the first transport stream, and generally includes a program association table (Program Association Table, PAT), a program map table (Program Map Table, PMT), a conditional access table (Conditional Access Table, CAT), and a network information table (Network Information Table, NIT). The service information SI is an extension of the program specific information PSI and mainly includes a network information table (Network Information Table, NIT), a service description table (Service Description Table, SDT), and an event information table (Event Information Table, EIT).

Wherein the PID number of the program association table PAT is "0x00", the program association table PAT gives PID values of the program map table PMT constituting each program service in the transport stream, and also gives PID values of the network information table NIT. The corresponding information such as the program map Table PMT, the network information Table NIT, the service description Table SDT, and the event information Table EIT can be parsed from the transport stream according to the PID value and the corresponding Table ID value.

The network information table NIT in the service information SI mainly includes information such as a network identifier (network_id), a network name, transmission system parameters (including frequency, modulation mode, symbol rate, etc.), a program service type, and a service identifier (service_id). After tuning to the transport stream carrying the NIT table, the channels may be automatically searched based on information extracted from the network information table NIT. The frequency information of the program can be obtained through the NIT table, and the service identification, the transport stream identification and the network identification of one program can be uniquely determined.

The service description table SDT includes: the type of service for the program (e.g., PAL, NTSC, SECAM, fm broadcast, teletext, near video on demand, etc.), service information (i.e., channel information), etc. The program name of a program can be obtained from the service description table SDT table, and the service identifier (service_id), transport stream identifier (transport stream_id) and network identifier (network_id) of a program can be uniquely determined.

The event information table EIT mainly comprises information such as program names, program broadcasting start time, program broadcasting time periods, parental control levels and the like, program introduction, program types (such as movies/drama, news, variety, sports, children, music, art, social politics, religions and the like), basic code stream types (such as video amplitude-type ratio, accompanying sound types, subtitle types and the like).

After the first transport stream is obtained, the contents of the network information table NIT, the service description table SDT, the event information table EIT and the like in the service information SI can be analyzed from the first transport stream by a comprehensive receiving Decoder (INTEGRATED RECEIVER Decoder, IRD) in the display device, so that a plurality of first transport streams corresponding to a plurality of programs can be analyzed by the above-mentioned flow, and the service information SI corresponding to a plurality of programs can be obtained. Further, service information SI corresponding to the plurality of programs may be stored in the display device to form a service information SI database.

S640: and controlling a display to display text information corresponding to each program in a program column corresponding to each program according to service information SI corresponding to a plurality of programs.

The display device can construct an electronic program guide containing program information of a plurality of programs according to information corresponding to each program in the service information SI. In other words, the display device may control the display to display text information corresponding to each program in the program columns corresponding to each program according to the service information SI corresponding to the plurality of programs, and the generated electronic program guide interface may refer to the electronic program guide interface 502 shown in fig. 5.

In the electronic program guide interface 502, a program list of each channel is displayed, and text information corresponding to each program is displayed in each program field, for example: the program name of the program broadcast by the channel 2 from 10:00 to 12:00 is '2023 Asian badminton tournament', and the program name of the program broadcast by the channel 2 from 12:00 to 13:00 is '2023 track and field tournament'; the program name of the program broadcast by the channel 1 from 10:00 to 11:00 is "Chinese 5 th set on the tongue tip"; the program name of the program broadcast by channel 3 at 11:00 to 12:00 is "family girl 24 th set", and so on.

Referring to fig. 8A to 8C, a schematic diagram of displaying an audio/video stream in a program field is shown.

As shown in fig. 8A, in the user interface 501 of the display device, the user may select a program field corresponding to a certain program (i.e., the second program) by switching the focus position, for example, the user selects a program field 503 corresponding to a program named "cat and mouse 8 th set". Then, the display device determines a second program parameter of a second program corresponding to the second focus position according to the focus position (namely, the second focus position).

The second program parameter may include a network information table NIT, a service description table SDT, and a network identifier (network_id), a transport stream identifier (transport stream_id), and a service identifier (service_id) included in the event information table EIT. Wherein a combination of network identification (network_id), transport stream identification (transport_id) and service identification (service_id) can uniquely identify a transport stream. Therefore, the display device can determine the first transport stream corresponding to the second program from the plurality of first transport streams stored in the memory according to the second program parameters.

Reference is made to a schematic diagram of an acquisition audio video stream shown in fig. 9.

After determining the first transport stream corresponding to the second program, the display device may then demodulate the first transport stream corresponding to the second program through a demultiplexer, and perform decoding processing through a decoder (Demux), so as to obtain a Video stream (Video ELEMENTARY STREAM, video ES) and an Audio stream (Audio ELEMENTARY STREAM, audio ES) corresponding to the second program (i.e., a second Audio-Video stream).

As shown in fig. 8B, after the second audio/video stream corresponding to the second program is obtained, the display device may control the display to display and play the second audio/video stream corresponding to the second program in the program field 503 corresponding to the second program.

In some embodiments, the user may further view a second program corresponding to the second focus position. For example, the user may input a determination operation for the second program corresponding to the second focus position through the controller, so that the second audio/video stream corresponding to the second program may be played in full screen in the electronic program guide interface 502.

Through the scheme in the embodiment, the electronic program guide interface is optimized, and the displayed program information is richer, so that a user can further know the program information of the second program through the second audio/video stream corresponding to the second program. Compared with the text information, the audio-video stream can better display the program information, so that a user can know the content played by the second program in more detail through the second audio-video stream, and whether to further watch the second program can be determined more clearly.

Further, the user may also input a focus switching operation at the electronic program guide interface through the controller, so as to switch the focus position from the second focus position to the first focus position. As shown in fig. 8C, for example, the user switches the focus position from the second program "sponge baby group 5" corresponding to the second focus position to the first program "family child group 25" corresponding to the first focus position.

Thus, the display device may respond to the above-mentioned focus switching operation input by the user on the electronic program guide interface, and likewise, the display device determines the first program parameter of the first program corresponding to the above-mentioned first focus position. The first program parameter may also include a network identifier (network_id), a transport stream identifier (transport_id), and a service identifier (service_id) included in the network information table NIT, the service description table SDT, and the event information table EIT.

S420: and acquiring a first transport stream corresponding to the first program according to the first program parameter.

Since the combination of the network_id, the transport_id, and the service_id can uniquely identify one transport stream, the display device can determine the first transport stream corresponding to the first program from the plurality of first transport streams stored in the memory according to the first program parameter.

S430: and analyzing the first transport stream corresponding to the first program to obtain a first audio/video stream corresponding to the first program.

The display device may demodulate the first transport stream corresponding to the first program through the demultiplexer and perform decoding through the decoder (Demux) in the same manner as the processing procedure of the first transport stream corresponding to the second program, thereby obtaining a Video stream (Video ES) and an Audio stream (Audio ES) corresponding to the first program (i.e., the first Audio/Video stream).

S440: the control display displays the first audio-video stream in a program field of the first program.

As shown in fig. 8C, after the first audio/video stream corresponding to the first program is obtained, the display device may control the display to display and play the first audio/video stream corresponding to the first program in the program field 503' corresponding to the first program.

In some embodiments, the user may further view the first program corresponding to the first focus position. For example, the user may input a determination operation for the first program corresponding to the first focus position through the controller, so that the first audio/video stream corresponding to the first program may be played in full screen in the electronic program guide interface 502.

With continued reference to fig. 8C, after the focal position is switched from the second focal position to the first focal position, for the second program corresponding to the second focal position, a target image frame may be determined according to a second audio/video stream corresponding to the second program, and the display may be controlled to display the target image frame in the program field 503 corresponding to the second program.

The target image frame may be a target image frame corresponding to a moment when the focus position is switched when the second audio/video stream is played; or a target image frame corresponding to the starting time of the second audio/video stream; the target image frame corresponding to the end time of the second audio/video stream can also be used; or the target image frame corresponding to any time in the second audio/video stream, etc., the selection mode of the target image frame is not limited in this embodiment.

In some embodiments, after the focal position is switched from the second focal position to the first focal position, text information corresponding to a second program corresponding to the second focal position may be displayed for the second program; or the text information of the script corresponding to the second program and the target image frame corresponding to the second program can be displayed together; or the second audio/video stream corresponding to the second program may be kept and displayed (may be subjected to mute processing), and the embodiment is not limited to this.

Through the scheme in the embodiment, the electronic program guide interface is optimized, and the displayed program information is richer, so that a user can further know the program information of the program through the audio and video stream corresponding to the program. Compared with the text information, the method has the advantages that the visual impact of the audio and video is stronger, the transmission efficiency is higher, the audience group is wider, the program information can be better displayed, so that a user can know the played content of the program in more detail through the audio and video stream, and whether the program is watched further or not can be determined more clearly. And the user can also view the audio and video streams corresponding to each program by switching the focus positions. After the focal positions are switched, for the programs in which the previous focal positions are, image frames in the audio and video streams corresponding to the programs can be reserved for being displayed for viewing and review by a user.

In some embodiments, referring to fig. 10, the controller may also perform the following method:

S1010: and determining a first program parameter corresponding to the first focus position in response to the video mode selection operation input by the user and the focus switching operation input in the electronic program guide interface.

For the electronic program guide interface 502, two display modes may also be provided, one being a text mode and the other being an audio/video/image mode. The user may input the selection operations of the two modes through a controller or the like, so as to determine a display mode of program information corresponding to each program in the electronic program guide interface 502.

If the user selects the audio/video/image mode, the audio/video stream or the image frame of the corresponding program can be displayed in the program field where the focus position is located, as in the embodiments shown in fig. 8A to 8C. That is, after a video mode selection operation input by a user, the display device responds to the video mode selection operation, responds to a focus switching operation input by the user on the electronic program guide interface, determines a first program parameter corresponding to a first focus position, acquires a first transport stream corresponding to the first program according to the first program parameter, analyzes the first transport stream corresponding to the first program to obtain a first audio/video stream corresponding to the first program, and controls the display to display the first audio/video stream in a program column of the first program; meanwhile, the display device determines a target image frame according to a second audio-video stream corresponding to the second program, and controls the display to display the target image frame in a program column of the second program.

S1010': and responding to the text mode selection operation input by the user, controlling the display to cancel the first audio/video stream in the program field of the first program, and controlling the display to delete the target image frame in the program field of the second program.

S1020: the display is controlled to display the text information corresponding to the first program in the program field of the first program, and the display is controlled to display the text information corresponding to the second program in the program field of the second program.

If the user selects the text mode after selecting the audio/video/image mode, the display device may control the display to cancel displaying the first audio/video stream played in the program field and display corresponding text information in the program field in response to the text mode selection operation input by the user; and controlling the display to delete the target image frame displayed in the program field, and displaying the corresponding text information in the program field.

For example, as shown in fig. 8C, the current display mode of the electronic program guide interface 502 is an audio/video/image mode, and if the user selects the text mode at this time, the display device controls the display to cancel displaying the first audio/video stream of the "family child 25 th set" played in the first program field 503 'and displays the corresponding text information "family child 25 th set" in the program field 503', in response to the text mode selection operation input by the user; and controlling the display to delete the target image frame displayed in the second program field 503, and displaying the corresponding text information "sponge baby 5 th set" in the program field 503.

It will be appreciated that the electronic program guide interface 502 keeps displaying text information corresponding to each program in the program fields of each program in text mode. That is, even if the focus position is switched, text information corresponding to each program is displayed.

It should be noted that the screen of the user interface in the display device may be divided into three layers, namely, a graphics layer (On SCREEN DISPLAY, OSD), a video layer and a background layer in this order. The graphic layer is used for displaying characters, graphics and images; the video layer is used for displaying a plurality of videos; the background layer is a screen image when no television program is being played and the electronic program guide interface is being activated. The electronic program guide interface is constructed in a graphic layer, and in an audio/video/image mode, when playing the audio/video stream of the program corresponding to the focus position, a player interface for playing the audio/video stream can be overlapped on the graphic layer.

In addition, the electronic program guide interface provided in the above embodiment is only an example, and the specific style, arrangement, and the like in the electronic program guide interface are not limited in this embodiment.

Through the scheme in the embodiment, the user can freely switch the display mode (including the audio/video/image mode and the text mode) of the electronic program guide interface, so that the user can select to view the audio/video stream or the text information of the program according to the requirement, and the user experience is improved.

In summary, by applying the technical scheme of the invention, the electronic program guide interface for displaying the recorded programs is optimized, so that the displayed program information is more abundant, and a user can know the program information of the programs through the corresponding text information and audio/video streams of the programs. Compared with the text information, the method has the advantages that the visual impact of the audio and video is stronger, the transmission efficiency is higher, the audience group is wider, the program information can be better displayed, so that a user can know the played content of the program in more detail through the audio and video stream, and whether the program is watched further or not can be determined more clearly.

And the user can also view the audio and video streams corresponding to each program by switching the focus positions in the electronic program guide interface. After the focus position is switched, for the programs in the previous focus position, the image frames in the audio and video streams corresponding to the programs can be reserved and displayed, and compared with the text information, the image frames can display the program information more intuitively. In addition, the user can freely switch the display mode (including audio/video/image mode and text mode) of the electronic program guide interface, so that the user can select to view the audio/video stream/image or text information of the recorded program according to the requirement of the user, and the user experience is improved.
