Description

Display method of channel list, smart TV and computer-readable storage medium

technical field

The present invention relates to the technical field of televisions, and in particular, to a method for displaying a channel list, a smart TV and a computer-readable storage medium.

Background technique

With the continuous development of smart TVs, users' requirements for the experience of smart TVs are also constantly improving, resulting in the need for smart TV-related manufacturers and service providers to optimize the software running in smart TVs and improve the operating efficiency of the software in smart TVs .

For example, with the comprehensive consideration of cost and user experience, low-cost smart TVs can also adopt a 4K solution to achieve playback effects, but the memory is required to be no more than 1G, and it is hoped that the functions and user experience of the smart TV will not be reduced. The 4K solution means that the smart TV uses 4K resolution for playback, and the 4K resolution is a resolution of 3840×2160 pixels.

However, if the above scheme is adopted to design a smart TV, a bottleneck will be encountered in processing the channel list of the smart TV. The reason is that, for example, European countries generally provide more than 3,000 channels from two satellites. Too many channels will slow down the operation of changing the channel list when the user uses the smart TV. And this is because the common method of processing the channel list is to directly find the appropriate programs in these 3,000 channels. When the above-mentioned smart TV design scheme is adopted to manufacture a smart TV, it will naturally be affected by the memory and the central processing unit. The performance of the Central Processing Unit (CPU) is low and the speed is slowed down. For example, when using a smart TV, if the channel list is turned over, the 3000 channels will be loaded into the memory first. However, due to the memory The low performance of the CPU naturally leads to a slowdown due to excessive consumption of hardware resources. Therefore, the existing smart TV has the technical problem that the processing speed of the channel list is slow when the hardware performance is low.

The above content is only used to assist the understanding of the technical solutions of the present invention, and does not mean that the above content is the prior art.

In this embodiment, by finding out the channel identifiers of the preset number of channels in each TV channel according to the above search method, it is not necessary to copy all the TV channels, and the list of channels to be displayed to which the channel identifiers of the preset number of channels are added is displayed, Therefore, the burden of the memory is reduced, and the technical problem of the slow processing speed of the channel list in the prior art when the hardware performance of the smart TV is low is solved.

Based on the above hardware structure, an embodiment of the display method of the channel list of the present invention is proposed.

Referring to FIG. 2 , FIG. 2 is a schematic flowchart of a first embodiment of a method for displaying a channel list according to the present invention.

In the first embodiment, the method for displaying the channel list includes the following steps:

Step S10: In response to the type switching instruction input by the user, determine the target channel type according to the type switching instruction;

It can be understood that the executive body of this embodiment is a smart TV. In order to not only consider the cost but also meet the user's requirements for the realization of smart TV functions, this embodiment not only hopes that the smart TV can achieve a 4K playback effect, but also can use a smaller memory, such as 1G memory, and the running performance However, when adopting the above-mentioned smart TV design scheme, in order to prevent the inability to provide a faster channel list response speed due to low hardware performance, this embodiment will first filter the channels instead of directly filtering all channels. Processing is performed to reduce the processing burden on the hardware.

In specific implementation, for example, if you want the smart TV to provide the same type of TV channels, the user can directly select the channel type on the physical buttons or virtual buttons of the smart TV, or the user can directly operate the remote control matching the smart TV to Determine the type of channel you want to display.

Step S20: Obtain the current channel ID of the current TV channel in the playing state, find the target channel ID of the TV channel closest to the current TV channel and belong to the target channel type, and use the target channel ID as a candidate for selection channel ID;

It should be understood that, after determining the channel type that the user wants to display, that is, the target channel type, in order to reduce the channel search range, a TV channel close to the current TV channel may be preferentially searched for. Because, after the user turns on the smart TV, it will automatically play a TV channel, that is, the current TV channel. Considering the user's usage habits, it will first search for the TV channel that is closest to the current TV channel and belongs to the user according to the default playback order of the TV channel. Determine the TV channel of the target channel type, and add the determined TV channel to the list of channels to be displayed. In this embodiment, all channels or all channels belonging to the target channel type are not directly displayed to the user, but the filtered list of channels to be displayed can be displayed to the user, which can reduce the burden of memory operation.

In a specific implementation, for example, the current channel identifier of the channel currently being played by the user is "Channel 7". Considering that the channel identifier in the playing state is preferentially displayed, if the current channel identifier that is "Channel 7" belongs to the target channel type, The current channel ID can be added to the list of channels to be displayed; and the target channel ID of the TV channel that is closest to the current TV channel and belongs to the target channel type will be searched. If it is played according to the default playback order of TV channels, it will be played sequentially. The closest channel to "Channel 7" is "Channel 8". If "Channel 8" does not belong to the target channel type, it will detect whether "Channel 9" belongs to the target channel type. If "Channel 9" belongs to the target channel type, then Add this "Channel 9" to the list of channels to show.

Step S30: adding the candidate channel identifier to the list of channels to be displayed, and searching for the next channel identifier belonging to the target channel type according to the candidate channel identifier as the associated channel identifier;

In a specific implementation, after adding the channel ID to be selected, namely "Channel 9" to the list of channels to be displayed, the next channel ID belonging to the target channel type, for example, "Channel 11", will be searched.

Step S40: Use the associated channel identifier as a candidate channel identifier, and return to the step of adding the candidate channel identifier to the list of channels to be displayed, until the number of channel identifiers in the list of channels to be displayed meets a preset number When the number of channels is present, the list of channels to be displayed is displayed.

It can be understood that, after adding "Channel 9" and "Channel 11" to the channel list to be displayed, the search for the candidate channel IDs that meet the requirements will continue until the number of channel IDs found meets the preset number of channels. For example, if the preset number of channels is 7, when there are 7 channel IDs added to the list of channels to be displayed, the search for channels will be stopped, and the list of channels to be displayed with 7 channel IDs stored will be displayed. Show all channels without having to search for all channels. Because it is not necessary to display all the channels or load all the channels into the memory, the display of the channel list is optimized and the display speed of the channel list is improved.

In this embodiment, by finding out the channel identifiers of the preset number of channels in each TV channel according to the above search method, it is not necessary to copy all the TV channels, and the list of channels to be displayed to which the channel identifiers of the preset number of channels are added is displayed, Therefore, the burden of the memory is reduced, and the technical problem of the slow processing speed of the channel list in the prior art when the hardware performance of the smart TV is low is solved.

Referring to FIG. 3 , FIG. 3 is a schematic flowchart of the second embodiment of the channel list display method of the present invention. Based on the first embodiment shown in FIG. 2 , a second embodiment of the channel list display method of the present invention is proposed.

In the second embodiment, the step S30 specifically includes:

Step S301: adding the to-be-selected channel identifier to the to-be-displayed channel list to obtain a preset linked list;

It can be understood that, in order to facilitate the smart TV to find the channel identifier, a preset linked list may be established to obtain the next identifier corresponding to the channel identifier to be selected. Referring to FIG. 4, FIG. 4 is a schematic diagram of a linked list. Wherein, in the preset linked list, the "channel ID" of the candidate channel ID itself, the "channel type" of the candidate channel ID itself, the next ID and the previous ID are preset.

Step S302: searching for the corresponding next TV channel belonging to the target channel type according to the channel identifier to be selected based on the preset linked list;

In a specific implementation, for example, if the channel ID of the channel ID to be selected is 3, referring to FIG. 4 , the corresponding next TV channel can be searched based on the preset linked list, and it can be seen that the next ID of the channel ID 3 is 5, indicating that the channel ID to be selected is 5. The channel ID of the next TV channel of the channel ID is 5. Of course, the previous TV channel corresponding to the identifier of the channel to be selected can also be queried according to the preset linked list.

Step S303: When the corresponding next TV channel belonging to the target channel type is found, the channel identifier of the found next TV channel belonging to the target channel type is used as the associated channel identifier.

It can be understood that, because the channel identifier of the channel to be selected finds the channel identifier of the corresponding next TV channel, that is, "next identifier 5" in the preset linked list, the "next identifier 5" can be used as the associated channel identifier.

Further, after the step S302, the method for displaying the channel list further includes: when the corresponding next TV channel belonging to the target channel type is not found, searching for the corresponding TV channel according to the list order of the preset initial channel list. The TV channel corresponding to the candidate channel identifier is the closest and belongs to the target TV channel of the target channel type, and the target TV channel is identified as the next channel corresponding to the candidate channel identifier in the preset linked list. TV channels belonging to the target channel type.

It can be understood that in the process of using the preset linked list, if the next logo of the channel logo to be selected is not found in the preset linked list, the next logo can be automatically added to the preset linked list to facilitate the next search. When reaching the channel identifier to be selected, the next identifier can be directly read from the preset linked list to speed up the response. Specifically, for example, if the channel identifier to be selected is 3, and the next identifier of channel identifier 3 is not recorded in the preset linked list, you can directly query in the preset initial channel list. The channel IDs from 1 to 3000 are recorded in a large order, and this embodiment does not limit the number of channels recorded in the preset initial channel list.

In a specific implementation, a query can be made in the preset initial channel list. For example, since the channel identifier to be selected is 3, it can be checked first whether the channel type of the channel with the channel identifier 4 is the same as the channel with the channel identifier 3, for example, The channel type of the channel with the channel ID 3 is A, and the channel type of the channel with the channel ID 4 is B. If the two channel types are different, continue to search backwards. If the channel type of the channel with the channel ID 5 is A, the recordable channel with the channel ID 5 is the target TV channel. In the preset linked list, the next identifier of the channel identifier 3 is recorded as 5, so that the channel 5 can be directly indexed in the next query.

In this embodiment, by establishing a preset linked list, the smart TV can quickly find the next logo of the current logo according to the preset linked list, so as to simplify the search process and further reduce the processing capacity of the smart TV.

Referring to FIG. 5 , FIG. 5 is a schematic flowchart of the third embodiment of the channel list display method of the present invention. Based on the first embodiment shown in FIG. 2 , a third embodiment of the channel list display method of the present invention is proposed.

In the third embodiment, after the step S40, the display method of the channel list further includes:

Step S50: In response to the list page-turning instruction input by the user, determine whether the list page-turning instruction is a down-turning instruction;

It can be understood that, after displaying a limited number of channel identifiers of the same channel type, page turning processing can be performed on the list of channels to be displayed on the page. Common page turning processing includes turning up and turning down.

Step S60: when the list page-turning instruction is the down-turning instruction, acquiring the channel identifier located at the bottom of the list of the to-be-displayed channel list;

It should be understood that, after obtaining the page down instruction input by the user on the smart TV or the remote control, the page turning process will be performed on the list of channels to be displayed currently displayed on the smart TV. Specifically, if the preset number of channels is 3, the channel identifiers included in the currently displayed channel list to be displayed are "channel 9", "channel 12" and "channel 17" from top to bottom. First, obtain the channel ID at the bottom of the list of the currently displayed list, that is, "channel 17".

Step S70: clearing the channel identifiers in the to-be-displayed channel list to generate a new to-be-displayed channel list;

In a specific implementation, in order to perform the page turning process, the three channel identifiers in the channel list to be displayed will be cleared first to fill in the new channel identifiers.

Step S80: searching for the sample channel identifier of the TV channel that is closest to the channel identifier at the bottom of the list and belongs to the target channel type, and uses the sample channel identifier as the candidate channel identifier;

It can be understood that a sample channel identifier that is close to the "channel 17" and belongs to the same target channel type will be searched first according to the default playing order of the TV channels, for example, the sample channel identifier is "channel 19".

Step S90: Return to the step of adding the channel identifiers to be displayed to the new channel list to be displayed, until the number of channel identifiers in the new channel list to be displayed meets the preset number of channels, display the new channel identifiers to be displayed. Show channel list.

It should be understood that searching for the channel IDs that are the closest and belong to the target channel type in order, for example, if the three channel IDs found are "channel 19", "channel 21" and "channel 27", it can be displayed that the channel IDs include the above The list of channels to be displayed with 3 channel identifiers, thus realizing the scroll down operation of the channel list. In addition, in the process of implementing the page turning operation of the channel list in this embodiment, the desired channel is firstly searched from all channel data, and then the desired channel is found, and then the desired channel is added to the channel list. Different from the prior art, in the prior art, all channel data is added to the memory and displayed in the channel list, and only 3 channel identifiers are provided each time for the user to view, but the solution in the prior art consumes both memory. , and the processing capacity is too large, because all channels need to be displayed in the channel list in advance, which requires relatively high computing resources for smart TVs.

However, in this embodiment, only the channels currently viewable by the user are loaded and displayed each time, which not only satisfies the viewing requirements of the user, but also reduces the burden on the memory and the processing capacity of the smart TV.

Further, after the step S60, the method for displaying the channel list further includes: acquiring the first channel identifier located at the top of the list of the channels to be displayed, and acquiring the channel whose focus is in the list of the channels to be displayed. Channel identification, calculating the difference between the channel identification at the top of the list in the channel list to be displayed and the channel identification where the focus is located;

Correspondingly, after the step S90, the method for displaying the channel list further includes: acquiring a second channel identifier at the top of the list of the new channel list to be displayed, and determining whether the new channel list to be displayed is related to the second channel in the new channel list to be displayed. Identify the channel IDs that differ by the identified amount as the updated channel IDs, and move the focus to the updated channel IDs.

It can be understood that, in order to realize the automatic transfer of focus when the smart TV turns pages, different from the prior art, the focus on the smart TV will be set at the top of the new list after the page is turned in the prior art. or the bottom end. However, when there are many options in the displayed list, the user needs to re-move the focus from the top or bottom, which is cumbersome for the user to operate. habit of use.

In a specific implementation, if the currently displayed channel list is "Channel 9", "Channel 12" and "Channel 17", the new channel list after turning the page is "Channel 19", "Channel 21" and "Channel 27" . In order to ensure that the relative position of the focus in the list does not change, for example, in the channel list before the page is turned, the focus is on "Channel 12", and the first channel ID at the top of the list is "Channel 9", and "Channel 9" is obtained. ” and “Channel 12” differ by the number of flags being 0.

It can be understood that, after the page is turned, in order to ensure that the relative position of the focus in the channel list does not change, since the focus is in "channel 12", that is, the second position in the list before the page is turned, the focus can be changed after the page is turned. In "Channel 21" i.e. second in the new list. The channel identifier "Channel 19" at the top of the list of the new list can be obtained first. Since the number of difference identifiers is 0, it indicates that it is at the next channel of "Channel 19", that is, at "Channel 21". Therefore, moving the focus to "Channel 21" means updating the channel ID, which also realizes setting the focus to the original position before turning the page.

In this embodiment, the page turning operation is realized by automatically searching for channels and loading only the number of channels required by the user. Compared with the prior art, this embodiment simplifies the running burden of the page turning operation, so that the response speed of the page turning operation can be faster. .

Referring to FIG. 6, FIG. 6 is a schematic flowchart of a fourth embodiment of a channel list display method of the present invention. Based on the first embodiment shown in FIG. 2, a fourth embodiment of the channel list display method of the present invention is proposed.

In the fourth embodiment, the step S10 specifically includes:

Step S10': in response to the type switching instruction input by the user, obtain the current channel type to which the TV channel in the playing state at the current moment belongs, search for the next channel type of the current channel type from the preset type list, and store the next channel type. A channel type as the target channel type.

It can be understood that, for the determination of the target channel type, in addition to the user directly inputting the channel type to be switched on the remote control to determine the target channel type, in addition, a preset type list can also be established. There will be a variety of channel types in the system. When the user inputs a type switching instruction on the remote control, the next channel type of the current channel type will be automatically selected from the preset type list as the target channel type to simplify the user's operation.

Further, before the step S10', the display method of the channel list further includes:

Step S101: in response to the initialization instruction input by the user, obtain each channel data, read the channel ID from the channel data, establish a channel ID list according to the read channel ID, and display the channel ID list;

It can be understood that, considering that the smart TV needs to use the fixed data of the corresponding channel when playing the TV content, so as to realize the playing of the TV content. The fixed data relates to channel configuration information, channel signal attribute information, and the like, such as channel name, number, and event (Event). It needs to be clear that the fixed data volume of the channel is relatively large, and each channel will have ten related data packets. Then, when the number of channels is thousands, the data packets corresponding to the channel will reach a considerable number of tens of thousands. Therefore, when the hardware performance of the smart TV is low, processing the above-mentioned tens of thousands of data packets has a large processing burden for the smart TV.

In the specific implementation, in order to overcome the above-mentioned excessive data processing burden due to the large amount of data, the channel data can be divided in advance, for example, the channel data can be divided into two parts: "channel ID + channel display content" . After the smart TV is initialized or the smart TV is turned on, the acquired channel data will be segmented to extract the channel identifier of the channel data, and the channel display content will not be processed first.

Step S102: In response to the identification selection instruction input by the user, select the channel identification to be displayed from the channel identification list according to the identification selection instruction, search for the corresponding display content of the channel to be displayed according to the channel identification to be displayed, and display all the channel identifications. the channel display content to be displayed, and the channel data includes the channel identifier and the channel display content.

It should be understood that when the smart TV is initialized, the channel display content is not processed first, which will also reduce the processing burden on the smart TV. However, the channel ID list including the channel ID can be displayed first for the user to view the channel. , to meet the browsing needs of users. When the user inputs the identification selection instruction, it indicates that the user has determined the specific channel to be watched, and the corresponding display content of the channel to be displayed can be found out according to the determined channel. viewing of channel content.

Further, after the step S101, the method for displaying the channel list further includes: enabling a preset background thread, so that the preset background thread searches for the corresponding channel display content according to the read channel identifier, and finds the The channel display content of , is saved to the internal memory.

It can be understood that, after dividing the "channel ID" and "channel display content", in order to further speed up the response speed of the channel display content after the user inputs the ID selection instruction, the preset can be automatically activated before the user inputs the ID selection instruction. The background thread is used to load the channel display content into the memory in the background. Since the user only checks the channel ID list at this time, the processing burden of the smart TV is relatively small. After the user inputs the logo selection instruction, the channel display content can be directly read from the memory, thereby speeding up the response speed of the channel display content, because at this time, the channel display content is downloaded again or the channel is obtained from a non-memory storage location The displayed content is louder at a slower speed.

In this embodiment, by establishing a preset type list, there is no need for the user to manually input the target channel type or manually select the channel type to be switched to. The smart TV can directly select the next channel type from the preset type list automatically, so as to realize the target channel The determination of the type can simplify the user's operation and improve the user experience.
