Among them, the channel attribute can be understood as an attribute related to the channel setting, and the channel attribute can include at least one of marking, locking, deleting, sorting, scheduled recording, audio track, and frequency. The channel editing operation can be understood as an operation in which a user edits the channel attributes of a channel, for example, adding certain channels to the favorite list, or deleting some channels that you don’t want to watch, or locking some channels, etc. Through the channel editing operation, the channel attributes corresponding to the channel can be edited (also referred to as modification or setting) to make it more in line with the user’s usage needs. Marking means that the user sets the degree of liking, disliking, or general for the channel. Locking means that the user encrypts the channel, such as a child lock, to avoid false triggering. Only when the correct password is entered can the content corresponding to the channel be played. Deleting means that the user deletes the channel. Sorting means that the user sorts the multiple channels searched, and the specific sorting method can be related to the user’s usage habits or other factors, which is not limited in this embodiment. Scheduled recording means that the user sets a timed recording function for the channel. Audio track means that the user sets the playback language for the channel, which is particularly suitable for scenarios in multilingual countries where users tend to choose a language they are familiar with when watching programs. Frequency is the frequency set by the user. It is applicable to areas with poor signal. Users may need to adjust the frequency to make the channel program play clearly. At this time, the modified channel frequency is the channel attribute. Channel attributes can also include other attributes related to channel settings, which are not listed here. The channel attributes corresponding to the channel editing operation can be understood as: the channel attributes edited when performing the channel editing operation for the channel searched after the last automatic channel search operation.

The user may trigger a button in a control device (such as a remote control), or trigger this automatic channel search operation through a mobile terminal, etc., or may trigger this automatic channel search operation through other methods, which are not limited in this embodiment. After receiving this automatic channel search operation, the at least one processor of the display device responds to this automatic channel search operation and obtains a channel list obtained after the last automatic channel search operation. When it is determined that the channel list contains channels, it may obtain channel attributes corresponding to the channel editing operation in the channels included in the channel list, specifically: the at least one processor of the display device determines the preset channels in the channel list that have been subjected to channel editing operations, obtains the attributes edited when the channel editing operation is performed on each preset channel, and The channel attributes of the display device are summarized as the channel attributes corresponding to the channel editing operation in the channel obtained after the last automatic channel search operation; when the at least one processor of the display device performs a channel editing operation on the channel obtained after the last automatic channel search operation, the channel attributes corresponding to the channel editing operation can be directly stored in the memory of the display device, so that the at least one processor of the display device responds to this automatic channel search operation and can directly obtain the channel attributes corresponding to the channel editing operation in the channel obtained after the last automatic channel search operation from the memory.

It should be noted that: the number of preset channels is at least one, the number of channel attributes is at least one, and the user can edit the same channel attribute on different channels, or can edit different channel attributes on different channels.

In some embodiments, the user can delete channel A and also delete channel B; the user can delete channel C and lock channel D.

S520: Control the display of the display device to display the channel attributes, obtain the channel attributes to be restored determined by the user from the channel attributes, and store the channel data and channel identification information corresponding to the channel attributes to be restored.

The channel attributes to be restored can be understood as the channel attributes to be retained selected by the user. The number of channel attributes to be restored is at least one, which can be determined by the user himself. This embodiment does not specifically limit this. The channel identification information is used to represent the identity information of the channel and distinguish different channels. The channel data can be understood as the setting data obtained after the user performs a channel editing operation on the channel attributes to be restored.

After acquiring the channel attributes corresponding to the channel editing operation in the channel obtained after the last automatic channel search operation, at least one processor of the display device controls the display to display the above channel attributes so that the user can determine the channel attributes to be restored from the channel attributes. After the user determines the channel attributes to be restored through the smart device or the control device, at least one processor of the display device acquires the channel attributes to be restored and stores the channel data and channel identification information corresponding to the channel attributes to be restored.

It should be noted that: Under normal circumstances, in the same area, the channels broadcast by a TV station generally do not change, and the content broadcast by the channel may be different every day, but for protocols of different standards, there is an identifier that can uniquely identify the channel, namely: channel identification information. For example, for digital television (Digital Television, DTV) signals, the channel identification information can be determined based on a combination of three fields: service identifier (ServiceID), transport stream identifier (TransportStreamId) and network identifier (NetWorkId); for analog television (Analog Television, ATV) signals, the channel identification information can be determined based on the frequency point, and the channel identification information can also be determined by other methods, which are not limited in this embodiment.

S530, after executing the automatic channel search operation, based on the channel identification information and channel data of each channel searched this time and the channel identification information corresponding to the channel attribute to be restored, an editing operation is performed on the target channel.

The channel identification information of the target channel is the same as the channel identification information corresponding to the attribute of the channel to be restored.

After executing this automatic channel search operation, at least one processor of the display device will obtain each channel searched this time, and can perform editing operations on the target channel according to the channel identification information of each channel searched this time, the channel data corresponding to the channel attributes to be restored, and the channel identification information corresponding to the channel attributes to be restored, that is: according to the channel data corresponding to the channel attributes to be restored, the target channel is set, and the relevant channel editing operations performed on the target channel after the last automatic channel search are re-edited to this target channel, so as to achieve the effect of automatic recovery.

In this embodiment, the above process controls the display to display channel attributes so that the user can determine the channel attributes to be restored, which is more user-friendly and more in line with user needs. When displaying channel attributes, not all channel attributes are directly displayed, but only the channel attributes corresponding to the channel editing operation (i.e., the modified channel attributes) in the channel obtained after the last automatic channel search operation are displayed, which can save user time, avoid too many channel attributes to be difficult to select, and avoid the situation where the user does not remember which channel attributes have been modified, resulting in a poor user experience. Accordingly, after executing this automatic channel search operation, the display device does not need to manually perform channel editing operations. Based on the channel identification information of each channel searched this time, the channel data corresponding to the channel attributes to be restored, and the channel identification information, the display device can automatically edit the corresponding channel, thereby automatically restoring the relevant channel data, which can not only simplify the operation, but also improve the user experience.

In some embodiments, optionally, the channel identification information of each channel searched this time, the channel The data and the channel identification information corresponding to the channel attribute to be restored, and performing an editing operation on the target channel may specifically include:

Specifically, since the channel identification information can represent the corresponding channel, at least one processor of the display device compares the channel identification information of each channel searched this time with the channel identification information corresponding to the channel attribute to be restored. If the channel identification information of each channel searched this time contains the same channel identification information as the channel identification information corresponding to the channel attribute to be restored, then the channel corresponding to the channel identification information is the target channel. After determining the target channel, the at least one processor of the display device performs the same channel editing operation on the target channel through the channel data, and can obtain the target channel data corresponding to the target channel. At this time, the at least one processor of the display device automatically restores the channel data corresponding to the channel attribute to be restored to the target channel.

In this embodiment, the above method can automatically achieve the channel data recovery effect without the need for manual operation by the user, which not only saves time but also improves the user experience.

In some embodiments, optionally, the above method may further specifically include:

In this embodiment, after storing the channel data and channel identification information corresponding to the channel attributes to be restored, at least one processor of the display device clears the channels obtained after the last automatic channel search operation and the channel data corresponding to the channel editing operation. Not only is the data that needs to be retained stored, but the clearing operation can also save storage space of the display device to avoid subsequent interference.

or,

Specifically, if the user does not determine the channel attributes to be restored from the channel attributes, it means that there are no channel attributes to be restored. At this time, in response to the user's operation of not determining the channel attributes to be restored from the channel attributes, at least one processor of the display device clears the channels obtained after the last automatic channel search operation and the channel data corresponding to the channel editing operation, and then executes this automatic channel search operation to obtain the channels searched this time. Alternatively, if the user does not perform a channel editing operation on the channels obtained after the last automatic channel search operation, it means that there are no channel attributes corresponding to the channel editing operation in the channels obtained after the last automatic channel search operation, and correspondingly, there are no channel attributes to be restored. At this time, in response to the user's operation of not editing the channels obtained after the last automatic channel search operation, at least one processor of the display device clears the channels obtained after the last automatic channel search operation, and then executes this automatic channel search operation to obtain the channels searched this time.

In this embodiment, in the above two situations, after the current automatic channel search operation is completed, at least one processor of the display device does not need to perform a channel data recovery operation, and can directly obtain the channels searched this time.

In some embodiments, optionally, the channel attribute includes a first channel attribute associated with a code stream; the above method may further specifically include:

In response to the user's editing operation on the first channel attribute, the first channel attribute is edited in the channel information in the display device, and the edited first channel data is stored in the target device in the display device. in the label module.

The first channel attribute can be understood as the channel attribute contained in the code stream, such as the order, channel name and channel number, etc. The target module is arranged in the bottom layer and mainly plays a storage role.

In this embodiment, since the code stream itself contains some channel attributes, when editing the channel attributes, if the user edits the first channel attribute of a channel, then at least one processor of the display device responds to the user's editing operation on the first channel attribute of the channel. It is necessary not only to edit the first channel attribute in the channel information in the display device, but also to store the edited first channel data in the target module in the display device, which is beneficial for subsequent distinction between whether the channel attributes are obtained from the code stream or edited by the user, thereby facilitating subsequent control of the display to display the channel attributes.

In some embodiments, optionally, the channel attribute includes a second channel attribute that is not associated with the code stream; the above method may further specifically include:

In this embodiment, since the second channel attribute is not associated with the code stream, when editing the channel attribute, if the user edits the second channel attribute of a channel, then at least one processor of the display device responds to the user's editing operation on the second channel attribute of the channel and directly edits the second channel attribute in the channel information in the display device, which is conducive to the subsequent acquisition of the channel attribute corresponding to the channel editing operation in the channel obtained after the last automatic channel search operation and controlling the display to display the channel attribute.

FIG5B is a schematic diagram of an interface of channels obtained after the last automatic channel search operation according to some embodiments of the present application.

Since the user did not check to delete, channel 4 will be displayed.

It should be noted that the channels included in FIG. 5B , FIG. 5D and FIG. 5E are only used for exemplary description and are not intended to be limiting.

FIG7 is a schematic diagram of the structure between the modules of a method for processing channel data for a display device according to some embodiments of the present application. FIG7 takes live TV (LiveTV) as an example to illustrate the modules for implementing the channel data processing method, wherein LiveTV includes a channel list module, a channel editing module, an automatic channel search module, a scheduled recording module, and a locking module, etc. These modules can be configured in at least one processor of the display device, and this embodiment does not limit this. The channel list module is used to receive some user operations and interact with other modules in LiveTV; the channel editing module is used to implement specific channel editing operations; the automatic channel search module is used to implement the automatic channel search function; the scheduled recording module is used to implement the scheduled recording operation; and the locking module is used to implement the locking operation. The bottom layer includes a target module for storing the first channel data obtained after editing the first channel attributes.

FIG8 is a schematic diagram of an interactive process corresponding to a channel data processing method for a display device according to some embodiments of the present application. FIG8 takes channel sorting and scheduled recording as examples to describe the difference between the two channel attributes when editing: for channel sorting, not only the channel number data needs to be written into the channel editing module, but also the corresponding channel information needs to be modified in the underlying target module; for scheduled recording, the scheduled data only needs to be written into the channel editing module.

Based on FIG. 7 , FIG. 8 describes a specific timing flow chart. As shown in FIG. 8 , the overall flow chart is described as follows:

1. The user clicks on automatic channel search;

2. The automatic channel search module queries the channel list module to determine whether the last automatic channel search operation has searched for a channel. If the channel has not been searched, there is no channel editing operation, and the channel can be directly cleared. If the channel is searched, step 3 is executed;

3. The automatic channel search module obtains channel attributes from the channel editing module and receives the channel attributes sent by the channel editing module;

4. The automatic channel search module controls the display to display channel attributes. It can display a check box to the user to only display the channel attributes corresponding to the channel editing operation among the channels obtained after the last automatic channel search operation, so that the user can select the channel attributes from the channel attributes. Determine the attributes of the channel to be restored. The user can check or uncheck the checkbox, then click the Start Automatic Channel Search button to proceed to step 5.

5. The automatic channel search module sends a storage instruction and a clearing instruction to the channel list module. The channel list module stores the channel data and channel identification information corresponding to the channel attributes to be restored, sends a clearing instruction to the underlying target module to make the target module delete the corresponding channel data, and sends a clearing instruction to the channel editing module to make the channel editing module delete the corresponding channel data;

6. The automatic channel search module starts to search channels automatically. The automatic channel search process is implemented by the underlying related framework. After the automatic channel search is completed, the underlying related framework sends a message that the automatic channel search is completed to the automatic channel search module. The automatic channel search module sends a message that the automatic channel search is completed to the channel list module.

7. After the channel search is completed, the channel list module sends a message to synchronize relevant channel data to the channel editing module based on the stored channel data and channel identification information corresponding to the channel attributes to be restored, so that the channel editing module can perform relevant editing operations, and sends a message to synchronize relevant channel data to the target module, so that the target module can perform relevant editing operations, thereby achieving the purpose of automatically restoring relevant channel data.

It should be noted that the modules included in FIG. 7 and FIG. 8 are only used for exemplary description and are not intended to be limiting.

In summary, the present application performs the above-mentioned channel data processing method for a display device on a display device. At least one processor of the display device first responds to the current automatic channel search operation, obtains the channel attributes corresponding to the channel editing operation in the channel obtained after the last automatic channel search operation, and then controls the display to display the channel attributes, obtains the channel attributes to be restored determined by the user from the channel attributes, and stores the channel data and channel identification information corresponding to the channel attributes to be restored. Finally, after performing the current automatic channel search operation, based on the channel identification information, channel data of each channel searched this time, and the channel identification information corresponding to the channel attributes to be restored, the target channel is edited. In the above-mentioned technical solution, by controlling the display to display the channel attributes so that the user can determine the channel attributes to be restored, it is more humane and more in line with the needs of the user. Therefore, after performing the current automatic channel search operation, the display device does not need to manually perform the channel editing operation. The display device can automatically perform the editing operation on the corresponding channel based on the channel identification information of each channel searched this time, the channel data and channel identification information corresponding to the channel attributes to be restored, thereby automatically restoring the relevant channel data, which can not only simplify the operation but also improve the user experience.

Display devices refer to terminal devices that can output specific display images, which can be terminal devices such as smart TVs, communication terminals, smart advertising screens, projectors, etc. Taking smart TVs as an example, smart TVs are based on Internet application technology, have open operating systems and chips, have open application platforms, can realize two-way human-computer interaction functions, and are TV products that integrate multiple functions such as audio and video, entertainment, and data to meet the diverse and personalized needs of users.

FIG9 is another software configuration diagram of a display device 200 according to some embodiments. In some embodiments, as shown in FIG9 , the system of the display device may include a kernel, a command parser (shell), a file system, and an application. The kernel, shell, and file system together constitute the basic operating system structure, which allows users to manage files, run programs, and use the system. After power-on, the kernel starts, activates the kernel space, abstracts hardware, initializes hardware parameters, etc., runs and maintains virtual memory, schedulers, signals, and inter-process communication (IPC). After the kernel starts, the shell and user applications are loaded. After startup, the application is compiled into machine code to form a process.

As shown in Figure 9, the system of the display device is divided into three layers, namely, the application layer, the middleware layer and the hardware layer from top to bottom. In some embodiments, the system of the display device also includes a UI layer (not shown in the figure), which is located above the application layer and receives data transmission from the application layer to realize the screen presentation of the display 260.

The application layer mainly includes commonly used applications on TV and application frameworks. Common applications are mainly applications developed based on browsers, such as HTML5 APPs and native applications.

The Application Framework is a complete program model that has all the basic functions required by standard application software, such as file access, data exchange, etc., as well as the user interfaces of these functions (toolbars, status bars, menus, dialog boxes).

Native apps can support online or offline, message push or local resource access.

The middleware layer includes various TV protocols, multimedia protocols, and system components. The basic services (functions) provided by the system software connect the various parts of the application system or different applications on the network, and can achieve the purpose of resource sharing and function sharing.

The hardware layer mainly includes HAL interface, hardware and driver. Among them, HAL interface is the unified interface for all TV chips to connect, and the specific logic is implemented by each chip. Drivers mainly include: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver, etc.

In some embodiments, the application layer of the display device 200 includes at least one application, such as a live TV application, a video on demand application, a media center application, an application center, etc. Different applications are used to implement different functions. By running different applications in the display device 200, different programs can be executed to implement different functions. For example, the corresponding playback screen can be displayed in the display device 200 through the live TV application or the video on demand application.

In some embodiments, the live TV application can provide live TV and broadcast TV through different signal sources. For example, the live TV application can use input from cable TV, wireless broadcast, satellite service or other types of live TV services to provide TV signals. In addition, the live TV application can display the media assets of the live TV signal on the display device 200.

In some embodiments, the video on demand application can provide videos from different storage sources. Unlike the live TV application, the video on demand provides media data from certain storage sources. For example, the video on demand can come from a cloud storage server or from a local hard disk storage containing stored video programs.

Based on the above application, in order to play the corresponding media asset screen in the display device 200, as shown in FIG10, in some embodiments, the display device 200 can communicate with the server 400 during use to achieve data interaction. For example, the user can trigger the display device 200 to display a channel list through an interactive instruction. The channel list may include multiple channel controls, and each channel control may include channel name information. The display device 200 can send a request for obtaining channel information to the server 400 in response to the interactive instruction input by the user. The user can request the corresponding media asset data from the server 400 by selecting a channel control in the channel list for the display device 200 to play.

When playing a live TV channel, in some embodiments, the display device 200 can also record the media asset items of each channel in the display device 200, that is, the program information in each channel, in real time, and then generate a playback list based on the program information played by each channel. For example, the display device 200 includes channels DC a, DC b, and DC c. In one day, channels DC a, DC b, and DC c will broadcast different programs live, and the program information of the historical playback of channels DC a, DC b, and DC c will be recorded in the playback list of the display device 200.

In some embodiments, when a user watches a channel's historical program through a playback list, the display device 200 also detects the viewing progress of the program to generate a viewing history record. When the user watches the program again, the display device 200 can automatically jump to the progress position of the last viewing according to the viewing history record to play the program to meet the user's need to continue watching. In addition, before the display device 200 jumps to the progress position of the viewing history record, the display device 200 can also pop up a confirmation window. The confirmation window may include options for continuing to watch and re-watching, so that the user can choose to continue watching the program or restart watching the program from the initial time in the confirmation window.

After receiving the acquisition request, the server 400 can extract the media asset items included in the corresponding channel from the storage module according to the acquisition request, and feed back the extracted media asset item information to the display device 200. The display device 200 then generates a channel list according to the media asset item information fed back by the server 400, and displays the channel list on the display 260, providing a channel navigation mechanism for the display device 200.

In some embodiments, the display device 200 may control the display 260 to display the channel list in response to a display instruction for displaying the channel list. The channel list includes a channel control, and one channel control corresponds to one channel. In order to facilitate users to switch channels through the channel list, the channel list is displayed above the level of the channel playback interface, and the size of the channel list is smaller than the channel playback interface. In this way, the user can observe the channel playback interface while using the channel list, thereby improving the user's interactive experience.

Furthermore, in order to realize data interaction between the display device 200 and the server 400, the display device 200 needs to establish a communication connection with the server 400. For example, the display device 200 and the server 400 can establish a communication connection via a transmission network. The display device 200 and the server 400 are connected to transmit interactive data via the transmission network.

In some embodiments, components for establishing a communication connection need to be provided on the display device 200 and the server 400, respectively. A communicator 220 may be provided in the display device 200, and a communication module may be provided in the server 400. The communicator 220 and the communication module may support at least one of the same communication modes at the same time to establish a communication connection relationship. For example, the communicator 220 on the display device 200 includes an optical fiber interface, so that the display device 200 can be connected to the network through the optical fiber interface; at the same time, the communication module of the server 400 also includes an optical fiber interface, and can also be connected to the network through the optical fiber interface to achieve a communication connection between the display device 200 and the server 400.

It should be noted that the display device 200 and the server 400 may also establish a communication connection relationship by other connection methods, such as wired broadband, wireless local area network, cellular network, Bluetooth, infrared, radio frequency communication, etc.

The connection relationship between the display device 200 and the server 400 can be "many-to-one", that is, multiple display devices 200 can establish a communication connection with the same server 400, so that the server 400 can provide services for multiple display devices 200. The connection relationship between the display device 200 and the server 400 can also be "many-to-many", that is, multiple display devices 200 can establish a communication connection with multiple servers 400, so that multiple servers 400 can provide different services for the display device 200 respectively. Obviously, in some application scenarios, the connection relationship between the display device 200 and the server 400 can also be "one-to-one", that is, one server 400 specifically provides services for one display device 200.

Based on the above-mentioned display device 200, when the server 400 transmits the data information of the channels in the channel list through the transmission network, the display device 200 can transmit and process the data information of the channels based on different signal formats. Among them, the data information of the channels includes channel information and channel media. In some embodiments, the display device 200 can support channels of one or more signal formats, such as ATSC (Advanced Television Systems Committee), ISDB and DVB (Digital Video Broadcasting) and other different types of signal formats. Among them, ISDB is the digital broadcasting system of DIBEG (Digital Broadcasting Experts Group).

The signal format is the method of signal formation, transmission and processing of the signal source connected to the display device 200. Each signal format has independent and complete parameters and overall standards of the functional system. Among them, the signal source can be a terrestrial wave, cable and other signal sources. When the display device 200 plays the channel media, it obtains the channel data information according to the signal format currently selected by the display device 200, and decodes and plays the channel media according to the signal format and the channel data information.

In some embodiments, the display device 200 supporting two or more signal formats also responds to the channel search instruction, detects the signal formats supported by the display device, and controls the display 260 to display the format selection interface, as shown in FIG11. Among them, the format selection interface includes format controls for various signal formats, and each format control corresponds to a signal format. The display device 200 monitors the manipulation events of the format selection interface, and in response to the selection event of the target format control in the format selection interface, obtains the channel information of the target format, so as to generate a channel list according to the channel information. The user can switch the channel playback interface of each channel in the channel list of the display device 200.

However, the channel list generated by the display device 200 can only display channels of one signal format, that is, the display device 200 can only select one signal format at a time through the format selection interface to complete the channel search of one signal format. At this time, if the user wants to watch channels of other signal formats, it is necessary to clear the channel data of the previous signal format and re-acquire the channel data according to the signal format to be watched through the format selection interface. In this way, if the user needs to switch channels of different signal formats in the display device 200, it is necessary to repeatedly search for channel information in the display device 200, which prolongs the time consumed by the display device 200 to switch channels of different formats, resulting in a decrease in the efficiency of switching channels of different formats. In addition, when the user wants to watch channels of two formats at the same time, the channel playback interfaces of different formats can only be displayed through two display devices 200, resulting in an increase in the viewing cost of channel media resources and a reduction in the user experience.

Based on the above application scenarios, in order to improve the problem of low efficiency of channel switching of different formats in the display device 200, some embodiments of the present application provide another channel data processing method for a display device, which is mainly used for switching channels of all formats, as shown in FIG. 12, including the following program steps:

S100: In response to a channel search instruction, detecting a signal format of a display device, and controlling the display to display a format selection interface.

After the display device 200 is turned on, the user can start the live broadcast application in the display device 200 to enable the display The device 200 is connected to different signal sources to display the channel playback interface of each channel. In order to obtain the channel information of the channel, the user can input a channel search command to the display device 200. Alternatively, the display device 200 can automatically generate a channel search command after powering on according to its own configuration information. The display device 200 responds to the channel search command, detects the signal format supported by the display device 200, and then generates a format selection interface based on the signal format. After the format selection interface is generated, the display device 200 controls the display 260 to display the format selection interface. Among them, the format selection interface includes at least one format control representing the signal format.

Since the display device 200 may only support one signal format, in order to speed up the response speed of the display device 200, in some embodiments, as shown in FIG13, when the display device 200 detects the signal format, it also detects the number of signal formats supported by the display device 200. If the number of signal formats is equal to 1, the corresponding channel information is obtained according to the signal format. When the display device 200 only supports one signal format, the display device 200 can only obtain channel information through this signal format. Therefore, when the number of signal formats of the display device 200 is 1, there is no need to display the format selection interface, and the channel information can be directly obtained according to the detected signal format. In this way, the time for the display device 200 to respond to the channel search instruction can be shortened, and the response speed of the display device 200 can be improved.

On the contrary, if the number of signal standards is greater than 1, the display 260 is controlled to display the standard selection interface, and the corresponding channel information is obtained according to the selected event of the standard selection interface. When the display device 200 supports two or more signal standards, the standard selection interface is generated according to the signal standards supported by the display device 200, so that the user can select the channel information to be searched through the standard selection interface.

For example, the display device 200 only supports one signal format, ATSC. The user sends a channel search command to the display device 200 through the remote control device that is matched with the display device 200. The display device 200 responds to the channel search command and detects the number of signal formats supported by the display device 200. When the number of signal formats is detected to be 1, the display device 200 searches for ATSC channel information according to the ATSC signal format.

In some embodiments, the channel search instruction may be input based on a channel search button of the control device 100. After the display device 200 is turned on, a control signal may be sent to the display device 200 by pressing the channel search button. The control signal carries the key value of the channel search button. After receiving the control signal, the display device 200 parses the key value of the channel search button in the control signal, and generates a channel search instruction in response to the key value of the channel search button.

In order to simplify the user's interactive operations, in some embodiments, when the display device 200 controls the display 260 to display the standard selection interface, it detects the standard type of the signal standard and generates a full-standard control and a sub-standard control according to the standard type of the signal standard. Among them, the full-standard control is used to represent all signal standards supported by the display device 200, and the sub-standard control has an associated relationship with the standard type. In addition, after the full-standard control and the sub-standard control are generated, the full-standard control and the sub-standard control are displayed in the standard selection interface. Since the user may not have enough understanding of the signal standard, in order to facilitate the user to operate the display device 200, by providing a full-standard control in the standard selection interface, the display device 200 can obtain channel information of all standards.

For example: the display device 200 supports two signal formats, ATSC and ISDB. After the user sends a channel search command to the display device 200, the display device 200 responds to the channel search command and detects the number of signal formats supported by the display device 200. When it is detected that the number of supported signal formats is 2, the display device 200 generates a sub-format control for ATSC, a sub-format control for ISDB, and a full-format control including both ATSC and ISDB signal formats. As shown in FIG. 14 , the display device 200 displays the ATSC sub-format control "ATSC", the ISDB sub-format control "ISDB", and the full-format control "ALL" in the format selection interface for the user to select.

S200: monitoring control events of the system selection interface.

After displaying the standard selection interface, the display device 200 can execute a corresponding program based on a control event of the standard selection interface. The control event can be a selection event of a standard control, a move event of a standard control, or a deletion event of a standard control. Therefore, the signal standard of the channel to be displayed can be selected through the standard selection interface.

For example, the display device 200 supports two signal formats, ATSC and ISDB, and the display device 200 displays the format selection page shown in FIG. 14. The user can select the format control on the format selection page through the control device 100. When the user performs a selection operation on the full format control, the display device 200 obtains the channel information of the two signal formats of ATSC and ISDB; when the user performs a selection operation on the ATSC sub-format control, the display device 200 obtains the ATSC signal. When the user performs a selection operation on the ISDB sub-standard control, the display device 200 obtains the channel information of the ISDB signal standard.

S300: In response to a selection event of a target standard control in a standard selection interface, acquiring channel information of the target standard.

The display device 200 monitors the control events of the standard selection interface, and when a selection event of a target standard control occurs in the standard selection interface, obtains the channel information corresponding to the target standard, wherein the target standard is the signal standard corresponding to the target standard control in the standard selection interface.

When the display device 200 acquires the channel information, it can call the middleware according to the target format to search for the corresponding channel information. That is, in some embodiments, when the display device 200 acquires the channel information of the target format, it calls the target format middleware according to the format type of the target format, and searches for the channel information of the target format through the target format middleware. For example, as shown in FIG15 , when the target format is ATSC, the ATSC middleware is called to search for the channel information; when the target format is ATSC and ISDB, the ATSC middleware and the ISDB middleware are called to search for the channel information respectively. After searching for the channel information, the display device 200 loads the channel information of the target format to write the channel information of the target format into the channel database through the target format middleware.

S400: configuring the standard attribute of the channel information according to the standard type of the target standard.

After the display device 200 obtains the channel information of the target standard, it adds the standard attribute to the channel information according to the standard type of the target standard. The obtained channel information can be distinguished and identified by the standard attribute. Among them, the standard attribute can be a preset field identifier, etc.

In some embodiments, when the display device 200 configures the standard attribute of the channel information according to the standard type of the target standard, the attribute identifier is generated according to the standard type of the target standard. The standard attribute is created in the channel information, and the attribute identifier is saved in the standard attribute. For example, the target standards are the ATSC signal standard and the ISDB signal standard, and the attribute identifiers are "ATSC" and "ISDB" respectively.

S500: Store the channel information in the channel database.

After the display device 200 configures the standard attributes of the channel information, the channel information is uniformly stored in the same channel database. When the target standard selected by the user is multiple signal standards, the standard attributes in the channel information are used to distinguish channels of different standards. The display device 200 can generate a channel list based on the channel database to play the corresponding channel screen through the channel list.

For example, when the display device 200 supports the ATSC signal format and the ISDB signal format, and the target format selected by the user is the ATSC signal format and the ISDB signal format, the display device 200 calls the ATSC and ISDB middleware to search for channel information respectively. As shown in FIG16 , after searching for the channel information, the format attribute of the channel information is configured, and "ATSC" is added to the channel information searched by the ATSC middleware; and "ISDB" is added to the channel information searched by the ISDB middleware. The channel information with the configured format attribute is then stored in the channel database of the display device 200.

S600: generating a channel list including channel information based on a channel database; and when a channel control in the channel list is in a selected state, controlling the display to switch and display a channel playing interface corresponding to the selected channel control according to a format attribute.

After the display device 200 stores the channel information in the channel database, it generates a channel list based on the channel information in the channel database. In this way, when a channel control in the channel list is in a selected state, the display device 200 can control the display 260 to switch and display the playback interface corresponding to the selected channel control according to the standard attribute, so as to realize hot switching of channels of different standards, thereby improving the switching efficiency of channels of different standards.

In order to facilitate the user to interact with the display device 200 through the channel list, in some embodiments, the display device 200 receives a display instruction for displaying the channel list, and controls the display 260 to display the channel list in response to the display instruction. The channel list includes a channel control and a standard switching control, and the channel control is used to display the channel name and standard type. The display device 200 displays the channel controls of different standards in the channel list in different partitions according to the standard attribute of the channel information. The user can switch between lists of different standards in the channel list to complete the switching of channels of different standards.

Therefore, the display device 200 monitors the manipulation event of the channel list, and in response to the selection event of the standard switching control, controls the display 260 to display the standard switching interface. The standard switching interface includes an option control of the standard type, and the standard switching interface is used to switch the standard type of the channel control displayed in the channel list. The standard switching interface can be displayed on the channel list. The format switching interface is located above the level of the channel list, and the size of the format switching interface can be smaller than the size of the channel list. In this way, when the user switches the format of the channel list based on the format switching interface, he can also observe the changes of the channel list in the lower layer at the same time.

For example, the display device 200 supports two signal formats, ATSC and ISDB, and the target formats selected by the user are ATSC and ISDB signal formats. After the user sends a display instruction of the channel list to the display device 200, the display device 200 displays the channel list shown in FIG17 on the display 260. After selecting the format switching control in FIG17, the display device 200 displays the format switching interface shown in FIG18 on the upper layer of the channel list. The format switching interface includes two format tabs, and the user can switch the channel content displayed in the channel list based on the tabs of the format switching interface.

Therefore, the display device 200 can update the content displayed in the channel list through the system switching interface. In some embodiments, the display device 200 monitors the manipulation events of the system switching interface, and in response to the selection event of the target option control in the system switching interface, parses the target system type corresponding to the target option control. The channel information of the target system type is obtained in the channel database, and the channel information corresponding to the target option control is saved to the list to be displayed. The list to be displayed is the content to be displayed in the channel list. After the display device 200 saves the channel information to the list to be displayed, it controls the display 260 to display the list to be displayed to update the display content of the channel list.

For example: the display device 200 supports two signal formats, ATSC and ISDB, and the target formats selected by the user are ATSC and ISDB signal formats. When the display device 200 displays the channel list shown in FIG12, the "Terrestrial Wave-ISDB" tab is selected through the format switching interface shown in FIG18. The display device 200 parses the target format type of the "Terrestrial Wave-ISDB" tab and searches the channel information corresponding to the "Terrestrial Wave-ISDB" tab in the channel information library. Then, the content of the channel list is updated according to the searched channel information, and the channel list shown in FIG19 is displayed.

In some embodiments, the display device 200 obtains the priority order of the option controls when displaying the format switching interface. The priority order is the arrangement order preset in the display device 200. After obtaining the priority order, the display device 200 displays the option controls in the format switching interface according to the priority order. For example, taking the display device 200 supporting two signal formats, ATSC and ISDB, as an example, the priority order preset in the display device 200 is "terrestrial wave-ATSC>terrestrial wave-ISDB>cable-ATSC>cable-ISDB".

Furthermore, in order to simplify the process of switching channels of different formats, a custom channel list may be created in the display device 200, and channels of different formats may be added to the custom list, so that the process of switching channels of different formats is easier. That is, in some embodiments, the display device 200 further creates a custom channel list, and in response to a move event of a channel control in the channel list, moves the channel control to the custom channel list, so as to switch the channel playback interface through the custom list. The number of custom channel lists may be one or more; when there are multiple custom channel lists, the custom channel list to which the channel control is to be moved may be selected by the control device 100.

After the display device 200 moves the channel control to the custom channel list, a display control of the custom channel list is generated in the channel list, so that the user can call up the display interface of the custom channel list in the display 260. And, when the display control is in the selected state, the display 260 is controlled to display the custom channel list. In this way, the user can move frequently used channels to the custom channel list according to his or her own habits. The moved channels can be of the same signal format or of different signal formats. When watching channel media through the display device 200, the custom channel list can be called up to switch channels, which can shorten the time for users to repeatedly search in the channel list, thereby improving the efficiency of channel switching.

In order to create a custom channel list in the display device 200, in some embodiments, the display device 200 receives a creation instruction of the custom channel list, generates the custom channel list in response to the creation instruction, and controls the display 260 to display an editing interface of the custom channel list. The editing interface of the custom channel list can be used to edit the name of the custom channel list, the channel controls included in the custom channel list, etc., and the user can add or remove channel controls in the custom channel list through the editing interface.

In some embodiments, when the display device 200 controls the display 260 to switch and display the channel playback interface corresponding to the selected channel control according to the standard attribute, the data stream type is detected according to the standard attribute. The data stream type is the channel media asset type set based on the standard type, and the display device 200 needs to obtain the corresponding media asset data stream according to the signal standard. After detecting the data stream type, the display device 200 obtains the channel media asset according to the data stream type, decodes the channel media asset, and controls the display 260 to display the channel playback interface of the channel media asset.

Based on the above another channel data processing method for a display device, some embodiments of the present application also provide a display device The display device 200, as shown in FIG20 , includes a display 260 and at least one processor 250. The display 260 is configured to display a channel playback interface and a format selection interface; the at least one processor 250 is configured to execute the following computer program stored in the memory of the display device 200 to enable the display device 200:

S100: In response to a channel search instruction, detecting a signal format of a display device, and controlling the display to display a format selection interface, wherein the format selection interface includes at least one format control representing the signal format;

S200: monitoring the control events of the system selection interface;

S300: In response to a selection event of a target standard control in the standard selection interface, acquiring channel information of a target standard, wherein the target standard is a signal standard corresponding to the target standard control in the standard selection interface;

S400: configuring the standard attribute of the channel information according to the standard type of the target standard;

S500: storing the channel information in a channel database;

S600: generating a channel list including the channel information based on the channel database; and, when a channel control in the channel list is in a selected state, controlling the display to switch and display a channel playback interface corresponding to the selected channel control according to the format attribute.

As can be seen from the above technical solutions, the display device and another channel data processing method for the display device provided in some embodiments of the present application can detect the signal format of the display device 200 in response to a channel search instruction, and display the format selection interface; monitor the manipulation event of the format selection interface, and obtain the channel information of the target format in response to the selection event of the target format control in the format selection interface; wherein the target format is the signal format corresponding to the target format control in the format selection interface; then configure the format attribute of the channel information according to the format type of the target format, and store the channel information in the channel database; the method generates a channel list containing channel information based on the channel database; and when the channel control in the channel list is in a selected state, the display 260 is controlled according to the format attribute to switch to display the channel playback interface corresponding to the selected channel control. The method can switch channels of different formats in the same channel list, and can improve the efficiency of switching channels of different formats.

The display device can watch the corresponding channel programs by connecting to a variety of different signal sources. For example, the signal source can be a ground wave, an antenna signal, etc. In order to facilitate the user to select channel programs, a channel list is also provided in the display device. The channel list includes multiple channel controls, and the user can select the corresponding channel control to make the display device play the corresponding channel program. Therefore, the user can edit the channel list according to his own habits and needs, such as sorting, deleting or restoring channels, so that the user can switch channel programs through the edited channel list.

However, since it is necessary to exit the channel playback screen and call up the channel editing interface in the setting interface of the display device when editing the channel list, it is necessary to frequently switch the display interface of the display device when editing the channel list, which increases the complexity of the channel editing process and reduces the channel editing efficiency of the display device.

Based on at least one of the above-mentioned applications included in the application layer shown in FIG. 9, in order to play the corresponding media asset screen in the display device 200, as shown in FIG. 21, in some embodiments, the display device 200 can communicate with the server 400 during use to achieve data interaction. For example, the user can trigger the display device 200 to display a channel list through an interactive instruction. The channel list may include multiple channel controls, and each channel control may include channel name information. The display device 200 can send a request for obtaining channel information to the server 400 in response to the interactive instruction input by the user. The user can request the corresponding channel information from the server 400 by selecting the channel control in the channel list for display and playback by the display device 200.

When playing live TV channels, in some embodiments, the display device 200 can also record the media asset items of each channel in the display device 200, that is, the program information in each channel, in real time, and then generate a playback list based on the program information played by each channel. For example, the display device 200 includes channels DC a, DC b, and DC c. In one day, channels DC a, DC b, and DC c will broadcast different programs live, and the program information of the historical playback of channels DC a, DC b, and DC c is recorded in the playback list of the display device 200.

Therefore, in some embodiments, the display device 200 monitors the manipulation events of the channel list, and in response to the selection event of the channel control in the channel list, requests the channel media assets corresponding to the channel control from the server 400. The channel media assets include video data and audio data. After the display device 200 obtains the channel media assets, it decodes and plays the channel media assets to continuously form a channel playback screen in the display device 200.

Furthermore, in order to realize data interaction between the display device 200 and the server 400, the display device 200 needs to establish a communication connection with the server 400. For example, the display device 200 and the server 400 can establish a communication connection through a transmission network, and the interactive data is transmitted between the display device 200 and the server 400 through the transmission network.

Based on the above-mentioned display device 200, the display device 200 can also perform editing operations on the channel information through the channel editing interface to update the display content of the channel list. In some embodiments, when the display device 200 displays the setting interface, the display device 200 responds to the selected event of the signal source control in the setting interface, controls the display 260 to display the channel setting interface as shown in Figure 22 in full screen, and performs editing operations on the channel information through the channel setting interface. As shown in Figure 22, there are many option controls in the channel setting interface, and it is not easy to find the option controls for editing operations in the channel setting interface, such as "show/hide channels". Therefore, the user can edit the channel information of the display device 200 through the channel setting interface according to personal habits and needs to update the edited content of the channel list. In this way, the content displayed by the channel list can be more in line with user needs, and the convenience of channel switching can be increased.

However, the above channel setting interface needs to call the setting interface, and then trigger the display through the control event of the setting interface, which increases the complexity of interactive operations when editing channel information. If the broadcast content of the channel is to be edited, it is necessary to exit the channel setting interface and switch to the channel playing screen. In this way, when editing the channel information, it is necessary to frequently switch the display screen of the display device 200, which prolongs the time consumed in editing the channel information and reduces the channel editing efficiency of the display device 200.

Based on the above application scenarios, in order to improve the problem of low channel editing efficiency of the display device 200, a display device 200 according to some embodiments of the present application, as shown in FIG23, includes a display 260, a user interface 280 and at least one processor 250. Among them, the display 260 is configured to display a channel playback screen and a user interface; the user interface 280 is configured to receive a control signal of the control device 100; and the at least one processor 250 is also configured to execute the following computer program stored in the memory of the display device 200 to enable the display device 200:

S100': In response to the channel editing instruction, control the display to display the channel editing interface.

After receiving the channel editing instruction, the display device 200 controls the display 260 to display the channel editing interface. The display level of the channel editing interface is higher than the display level of the channel playback screen, and the size of the channel editing interface is smaller than the size of the channel playback screen. Therefore, since the size of the channel editing interface is smaller than the size of the channel playback screen, the display device 200 will not cover the entire channel playback screen when displaying the channel editing interface. In this way, when editing channel information, the user can also observe the lower layer channel playback screen at the same time, without having to repeatedly switch between the channel editing interface and the channel playback screen, which can improve the editing efficiency of the channel information.

In some embodiments, the display device 200 receives a display instruction for displaying a channel list, and in response to the display instruction, controls the display 260 to display the channel list. The channel list includes a channel editing control. After displaying the channel list, the display device 200 monitors a manipulation event of the channel list, and generates a channel editing instruction in response to a selection event of a channel editing control in the channel list.

For example, after the display device 200 receives a display instruction for displaying a channel list, a channel list is displayed as shown in FIG24, and the channel list includes a channel editing control. After the user selects the channel editing control through the remote control of the display device 200, the display device 200 displays a channel editing interface as shown in FIG25. In FIG25, the channel editing interface is half-screen displayed on the level of the channel playback screen, so the user can edit the channel information in the channel editing interface while observing the content of the channel playback screen.

It should be noted that when the display device 200 displays the channel editing interface, it displays the channel editing interface according to a preset size. In order to ensure the display effect of the channel editing interface, the channel editing interface can be 1/2 or 2/3 of the channel playback screen. This application does not limit this.

Alternatively, in some embodiments, the channel editing instruction may also be generated based on a specific button trigger in the control device 100. That is, when the control device 100 sends an editing instruction control signal to the display device 200 through the editing instruction control element, the display device 200 generates a channel editing instruction in response to the editing instruction control signal.

As shown in FIG. 26 , in some embodiments, the display device 200 is configured with a video display layer (VIDEO layer) and an on-screen display layer (On Screen Display, OSD layer); wherein the video display layer is used to display the channel playback screen, and its display ratio is full-screen display; the on-screen display layer is used to display user interfaces such as a channel list and a channel editing interface. The video display layer and the on-screen display layer are displayed in an overlapping manner, and the on-screen display layer is located above the video display layer.

S200’: Receive a first editing signal sent by a first control device.

After displaying the channel editing interface, the display device 200 also needs to perform corresponding editing operations according to the control signal input by the control device. Therefore, after displaying the channel editing interface, the display device 200 receives the control signal, i.e., the first editing signal, sent by the first control device 101. The first control device 101 includes a preset number of control elements, which are used to generate control signals.

For example, the first control device 101 is a remote controller, and the control element is a remote controller button. When the remote controller button is pressed, the remote controller sends a control signal corresponding to the remote controller button to the display device 200. The control signal includes the key value of the remote controller button, which is used to control the display device 200 to execute the corresponding program.

S300': Perform an editing operation on the channel information according to the first editing signal to generate editing record information.

After receiving the first editing signal sent by the first control device 100, the display device 200 performs an editing operation on the channel information according to the first editing signal, such as sorting, deleting or restoring channels. At the same time, after performing the editing operation on the channel information, the display device 200 also generates editing record information. The editing record information is used to update the channel list. Therefore, when displaying the channel list, the display device 200 displays the channel list according to the parameters recorded in the edit record information.

In some embodiments, the display device 200 receives a display instruction for displaying a channel list, and in response to the display instruction, obtains the editing record information. Then, the channel list is displayed according to the editing record information. The channel list includes a channel editing control. And, when the channel editing control is in a selected state, a channel editing instruction is generated. That is, before displaying the channel list, the display device 200 needs to obtain the editing record information first, and then display the channel list according to the parameters recorded in the editing record information, so that the channel list can update the display content in real time according to the user's editing operation.

In order to facilitate recording the editing operation of the channel information, in some embodiments, the editing record information is configured with multiple flags, including a channel number flag and a display flag. The channel number flag is used to represent the channel number of the channel information, and the display flag represents the display state of the channel information, including a display state and a hidden state.

For example: the editing record information is shown in the following table, and the editing record information includes the default channel number, the edited channel number, and the user deletion flag. Among them, the edited channel number is the channel number flag, which is used to display the channel number of the channel information; after the channel information is sorted, the display device 200 will modify the parameters of the channel number flag accordingly. The default channel number is an auxiliary flag of the channel number flag, which is used to display the channel number according to the parameters of the default channel number when no sorting editing occurs. Whether the user deletes is a display flag, which is used to display or hide the corresponding channel information; after the channel information is deleted or restored, the display device 200 will modify the parameters of the display flag accordingly.

In some embodiments, the display device 200 obtains channel information and edit record information when displaying a channel list. The channel number flag of the edit record information is detected. If the parameter of the channel number flag is a default parameter, the channel information is marked as the default channel number; if the parameter of the channel number flag is not a default parameter, the channel information is marked as the channel number corresponding to the channel number flag parameter. After marking the channel number of the channel information, the display device 200 also detects the parameter of the display flag. If the parameter of the display flag is the first parameter, the channel information is added to the list to be displayed. Among them, the first parameter is used to characterize the channel control for displaying the channel information. After traversing all the channel information, the display device 200 controls the display 260 to display the list to be displayed to update the channel list.

In some embodiments, the edit record information is shown in the following table:

As shown in FIG27 . After acquiring the channel information and the editing record information of the channel information, the display device 200 detects the "edited channel number" flag. The default parameter of the "edited channel number" flag is a negative number, such as -1. If the user performs an editing operation on the channel information, the parameter of the "edited channel number" flag is changed to a positive number corresponding to the channel information. When the display device 200 detects that the "edited channel number" flag is a positive number, the parameter of the "edited channel number" flag marks the channel number of the channel. On the contrary, when the display device 200 detects that the "edited channel number" flag is a negative number, the channel number of the channel is marked according to the parameter of the "default channel number" flag. After marking the channel number, the display device 200 detects the parameter of the "user deleted" flag. The parameter of the "user deleted" flag can be "N" or "Y", "N" is the first parameter, representing the channel control that displays the channel information; "Y" is the second parameter, representing the channel control that hides the channel information. The display device 200 adds the channel information with the parameter "N" to the to-be-displayed list, and controls the display 260 to display the to-be-displayed list.

In some embodiments, when the display device 200 performs an editing operation on the channel information according to the first editing information, it parses the key value of the first editing signal and queries the corresponding editing type according to the key value. If the editing type is a recovery type edit, the display device 200 controls the display 260 to display a history deletion table to restore the deleted channel control through the history deletion table. Among them, the channel control is associated with the channel information, that is, one channel control corresponds to the channel information of one channel. Different control components of the first control device 101 can generate different control signals and send the control signals to the display device 200. The display device 200 then executes the corresponding program by parsing the key value contained in the control signal.

For example, the first control device 101 is a complex remote controller, and the control components in the complex remote controller include four-color buttons and direction buttons. When the red button in the four-color buttons is pressed, the complex remote controller sends a control signal for restoring the editing to the display device 200. The display device 200 responds to the control signal for restoring the editing and controls the display 260 to display the history deletion table shown in FIG28. The history deletion table includes a channel control for deleted channel information, and the user can restore the deleted channel information by selecting a channel control in the history deletion list.

The display device 200 can restore the deleted channel information through the manipulation events in the history deletion table. Therefore, in some embodiments, the display device 200 monitors the manipulation events of the history deletion table, and in response to the selection event of the target channel control in the history deletion table, moves the target channel control to the channel editing interface. In the editing record information of the target channel control, the parameter of the display flag is modified to the first parameter. The first parameter is used to characterize the display target channel control.

For example, taking the first control device 101 as a complex remote controller, the control components in the complex remote controller include four-color buttons and direction buttons. The complex remote controller controls the focus movement through the up and down buttons in the direction buttons. When the cursor is located at the position of the DC f channel control shown in FIG28, the left button of the direction button generates a control signal for restoring the DC f channel, so that the display device 200 performs the restoration type editing of the DC f channel, and the display flag bit parameter in the DC f editing record information needs to be changed to the first parameter. In this way, when the display device 200 displays the channel list, it displays the channel list shown in FIG29.

Since the display device 200 may have multiple channel lists, in some embodiments, the display device 200 further controls the display 260 to display a list selection interface in response to a selection event of a target channel control in the history deletion table. The list selection interface includes the channel list option controls included in the display device 200. The display device 200 may move the target channel control to the corresponding channel list according to the channel list selection interface.

Similarly, if the editing type is a deletion type editing, the display device 200 controls the display 260 to display a deletion confirmation interface. The deletion confirmation interface is used to select whether to perform a deletion operation on the target channel control; the deletion confirmation interface includes a confirmation control and a cancel control, and the target channel control is a channel control in a selected state. By displaying the deletion confirmation interface, the problem of user misoperation can be improved.

For example, taking the first control device 101 as a complex remote controller, the control components in the complex remote controller include direction buttons. The complex remote controller controls the focus movement through the up and down buttons of the direction buttons. When the cursor is located at the position of the DC c control shown in FIG30, the right button of the direction button generates a control signal for deleting the DC c channel, so that the display device 200 controls the display 260 to display the deletion confirmation interface shown in FIG31.

The display device 200 can select whether to delete the target channel control through the deletion confirmation interface. Therefore, in some embodiments, the display device 200 monitors the manipulation event of the deletion confirmation interface, and in response to the selection event of the confirmation control in the deletion confirmation interface, moves the target channel control to the historical deletion table. And in the edit record information of the target channel control, the parameter of the display flag is modified to the second parameter. The second parameter is used to characterize the hiding of the target channel control.

For example: Take the first control device 101 as a complex remote control, in which the control components include direction buttons. When the display device 200 displays the deletion confirmation interface shown in FIG31, the focus is moved to the "Confirm" control through the direction buttons of the complex remote control, and the "Confirm" control is selected through the confirmation button of the direction buttons of the complex remote control. The display device 200 then performs the deletion type editing of the DC c channel, and the display flag parameter in the DC c editing record information needs to be changed to the second parameter. In this way, when the display device 200 displays the channel list, it displays the channel list shown in FIG24.

In some embodiments, if the editing type is sorting editing, the display device 200 moves the target channel control in the selected state out of the channel editing interface; and, in response to a selection event of a target position in the channel editing interface, moves the target channel control to the target position. That is, when the display device 200 sends an editing signal of sorting editing through the first control device 101, the display device 200 can move the channel control out of the list in the channel editing interface, and then move the channel control according to the position selected by the first control device 101 to re-sort the channel list.

Therefore, in some embodiments, when the display device 200 moves the target channel control to the target position, the target position is detected in the channel editing interface. The target position is the position of the focus when the selection operation is triggered in the channel editing interface. Then the target channel control is moved to the target position; and in the editing record information of the target channel control, the channel parameters of the channel number flag are modified to the channel parameters of the target position.

For example, taking the first control device 101 as a complex remote controller, the control components in the complex remote controller include direction buttons. The complex remote controller controls the focus movement through the up and down buttons of the direction buttons. When the cursor is located at the position of the DC C control shown in FIG30, the left button of the direction button generates a control signal for sorting the DC C channels, so that the display device 200 moves the DC C control out of the channel editing interface. After moving out of the DC C control, the focus movement is controlled by the up and down buttons in the direction buttons. At the position to be moved, the confirmation button in the direction buttons generates a control signal for selecting the first row position, so that DC C moves to the first row position, and the display device 200 displays the channel list shown in FIG32.

If the editing type is a checkbox edit, the display device adjusts the channel editing interface to a checkbox state and monitors manipulation events of the channel editing interface; and, in response to a selection event of a target channel control in the channel editing interface, marks the target channel control as a selected state.

For example, the first control device 101 is a complex remote controller, and the control components in the complex remote controller include direction buttons. The complex remote controller generates a control signal for entering the check state through the confirmation button in the direction buttons, so that the display device 200 adjusts the channel editing interface to the check state. As shown in FIG. 33 , the channel editing interface in the check state can perform selection operations on multiple channel controls at the same time to batch edit the channel information of the display device 200, which can improve the efficiency of channel editing.

In addition, in order to facilitate real-time observation of the playback content of each channel, in some embodiments, the display device 200 also obtains the position of the focus in the channel editing interface. If the focus is located on the target channel control of the channel editing interface, and the channel playback screen is not the playback screen corresponding to the target channel control, the dwell time of the focus is recorded. When the dwell time reaches the time threshold, the current signal source channel is switched to the channel corresponding to the target channel control, and the display 260 is controlled to display the playback screen corresponding to the target channel control. In this way, the display device 200 can delay the display of the channel playback screen of each channel, which can meet the needs of real-time observation of the playback content, and will not cause the channel playback screen to switch too frequently, which can enhance the user experience.

For example, the time threshold is 1.5s, and the user controls the focus movement of the channel editing interface through the control device 100. As shown in FIG14, when the focus is located at the position of the DC c control, the video display interface of the display device 200 displays the playback screen of the DC a channel. At this time, the display device 200 starts to count the time the focus stays at the DC c control. When the stay time is equal to 1.5s, as shown in FIG34, the current signal source channel is switched to the playback screen of the DC c channel.

In some embodiments, the first control device 101 includes a digital button, and a control signal for switching the signal source channel can be sent to the display device 200 through the digital button of the first control device 101. After receiving the control signal for switching the signal source channel, the display device 200 queries the channel information corresponding to the channel number according to the digital number included in the control signal, and controls the display 260 to switch the current signal source channel to the channel corresponding to the digital number.

The difference is that the second control device 102 of this embodiment has fewer control components compared to the first control device 101. When a control signal is sent to the display device 200 through the second control device 102, the display device 200 displays a control auxiliary interface. The control signal generated by the auxiliary control included in the control auxiliary interface may be equivalent to the control signal generated by the control component in the first control device 101 to complete the editing operation of the channel information.

For example, the second control device 102 is a minimalist remote controller. The minimalist remote controller includes an editing function button and a direction button, and sends a control signal for displaying the control auxiliary interface to the display device 200 through the editing function button. The display device 200 displays the control auxiliary interface shown in FIG. 20. The control auxiliary interface shown in FIG. 36 includes an auxiliary selection control. And numeric keys.
