The above-mentioned display device displays a search mode setting interface to configure multiple options for the user to make flexible choices, and then determines the search mode desired by the user based on the options selected by the user, thereby searching for the target channel the user wants. Compared with the signal frequency, All channels are searched continuously in order from high to low. The display device provided by the embodiment of the present disclosure meets the personalized needs of users, and the time consumed when searching for channels is shorter, which brings a better user experience.

In addition, the display content of current display devices (such as smart TVs) may contain some indecent information, such as sex, violence, and indecent language, which may have a negative impact on minors. For this reason, display devices usually provide a password lock function, which not only locks the program itself containing indecent information and prohibits users from watching it, but also locks the program information (such as program name, program play time, etc.) so that it is not displayed on the UI. Then, the channels of the display device (for example, the target channel obtained through the above-mentioned content search) can be divided into two types, one is the locked channel, and the other is the normal channel. A locked channel is a channel that is locked by a password lock so that users need to enter a password at least part of the time before they can watch it. Normal channels are non-locked, that is, users can directly watch the program content of normal channels without entering a password.

In the related technology, switching between normal channels and locked channels and switching between normal channels and normal channels are supported. In the scenario of switching from a normal channel to a locked channel, the processor of the display device first determines that the channel to be switched is a locked channel and obtains the program content of the unlocked channel. However, because the channel is locked, the locked channel is not immediately displayed. program content, the processor controls the display of the password input interface, as shown in Figure 4A. Figure 4A is a schematic diagram of the password input interface. The display 260 of the display device 200 shown in the figure includes a channel list 15, a video display area 16 and a password. Input interface 17, the user can input password information for the password input interface 17 to unlock the password channel.

When the display device has displayed the password input interface, the user may accidentally exit the password input interface. At this time, the user interface of the display device is as shown in Figure 4B. Figure 4B shows the user interface after exiting the password input interface in the prior art. Show schematic. The display 260 of the display device 200 shown in the figure includes a channel list 15 and a video display area 16. There is an occlusion element 21 in the video display area 16 to remind the user that the current channel is a locked channel and the locked channel is not output. The video and audio included in the program content can be understood as the video display area 16 being a blank interface. The user selects the locked channel again, and the user interface of the display device remains as shown in Figure 4B.

If you want to bring up the password input interface again, you need to switch from the currently selected locked channel to another channel based on the channel switching logic, and then switch back to the locked channel before the password input interface can be displayed again. This method is cumbersome to operate and has poor flexibility in channel switching, which affects the user experience.

In view of the above method, the inventor of the present disclosure found that the existing channel switching logic does not support the logic of switching the same channel. Therefore, when the channel is in a locked channel and the password input interface is exited, it will not respond to selecting the current channel again. The command to lock the channel switches from the currently locked channel to the current channel again.

In order to solve the above technical problems, in some embodiments of the present disclosure, the display device obtains the program content of the current channel through the processor when it is in the current channel, and responds to the selection instruction for the current channel to execute re-entering the current channel. Operation of the channel; when re-entering the current channel in response to the selection command, first determine whether the current channel is in the locked state. When the current channel is in the locked state, control the display to display the password input interface, and then obtain the password input interface for the current channel. Unlock input, and determine the password information corresponding to the unlock input, then unlock the current channel based on the password information, and control the display to play the program content of the current channel, which satisfies the situation that the user is already in the current channel and the current channel is in a locked state. In order to re-call the password input interface and unlock it, the user only needs to re-select the current channel, which is easy to operate, improves the logic of switching for the same channel, and improves the flexibility of channel switching.

It can be understood that the display device provided in some embodiments of the present disclosure, which will be described in detail below, can switch to the same locked channel to evoke the password input interface again, and can be a channel search using the content described above. The display device may also be a display device that does not use the above-mentioned content to perform channel search. The following will mainly take the latter as an example for explanation.

In some embodiments of the present disclosure, the processor 250 is configured to execute computer instructions to cause the display device to perform: when in the current channel, obtain the program content of the current channel, and in response to the selection instruction for the current channel, determine Whether the current channel is in a locked state; when the current channel is in a locked state, control the display to display the password input interface; obtain the unlock input for the password input interface, and determine the password information corresponding to the unlock input; unlock the current channel according to the password information , and control the display to play the program content of the current channel.

The above display device not only supports the logic of switching between normal channels and between normal channels and locked channels, but also supports the logic of switching between locked channels and locked channels, especially the same locked channel. switching logic. It meets the user's need to re-call the password input interface and unlock it when the current channel is in the locked state. The user only needs to re-select the current channel. The operation is simple and perfect for the same channel. The switching logic improves the flexibility of channel switching.

The channel switching instruction includes the first identifier of the target channel; and changes the first identifier of the target channel. The first identifier is compared with the second identifier of the current channel; if the first identifier and the second identifier match, it is determined that the channel switching instruction is a selection instruction for the current channel.

In some embodiments of the present disclosure, after the processor 250 is configured to execute the computer instructions to cause the display device to perform the step of comparing the first identification of the target channel and the second identification of the current channel, it is further configured to: Execute computer instructions to cause the display device to perform: if the first identifier and the second identifier do not match, obtain the program content of the target channel; switch from the current channel to the target channel, and determine whether the target channel is in a locked state; When the channel is unlocked, control the display to display the program content of the target channel.

In some embodiments of the present disclosure, the processor 250 is configured to execute computer instructions to cause the display device to perform the step of unlocking the current channel according to the password information, and is further configured to execute computer instructions to cause the display device to perform: The password information is compared with the preset password information; if the password information matches the preset password information, the current channel is unlocked.

For example, in the scenario shown in FIG. 1A , taking the user operating the display device 200 through the control device 100 as an example, the control device 100 sends a channel switching instruction to the display device. The instruction instructs to switch from channel 2 to channel 1, where the channel 1 is a locked channel. Upon receiving the instruction, the display device 200 performs switching from channel 2 to channel 200. 1, since channel 1 is a locked channel and requires password information to unlock, the display device 200 controls the display of the password input interface to obtain the user's unlock input for the password input interface. However, at this time, the user exits the password input interface by operating the display device 200 through the control device 100. Referring to FIG. 4B, the display device 200 does not display the program content of channel 1, and controls the display of occlusion elements to prompt the user where he is currently. Channel 1 is still locked.

In the scene shown in Figure 1A, the user operates the display device 200 through the control device 100 to lock channel 1, and sets channel 1 to be locked after 21:00, so that the user is no longer supported to continue watching, as shown in Figure 5 5 is a schematic diagram of the application scenario of the display device provided by the embodiment of the present disclosure. In Figure 5, channel 1 is used as a normal channel before 21:00, and the video display area 16 normally displays the program content of channel 1; after 21:00, channel 1 is used as a normal channel. 1 changes to a locked channel, the video display area 16 no longer displays the program content of channel 1, and can be in a black screen state, and the blocking element 21 is displayed in the video display area 16. If the user wants to continue watching channel 1, he needs to enter password information Unlock it and watch the program content again after unlocking it. It can be understood that the embodiments of the present disclosure are not limited to the above two application scenarios.

In any of the above application scenarios, the display device is in the current channel (channel 1). On the one hand, it obtains the program content of the current channel to play the program content normally after the current channel is unlocked; on the other hand, the display device receives the program content for the current channel. In the case of a channel selection instruction, in response to the selection instruction, it is determined whether the current channel is in a locked state. If the current channel is in a locked state, control the display to display the password input interface, and then obtain the user's unlock input for the password change input interface, determine the password information corresponding to the unlock input, decode the current channel according to the password information, and control The display plays the program content of the current channel. In this way, the present disclosure does not require at least two steps of switching from the current channel to other channels and then switching back to the current channel. The user only needs to select the current channel again to recall the password input interface. The operation is simple and the channel switching logic is improved. In addition, the logic to support switching for the same channel has been improved, and the flexibility of channel switching has been improved.

In addition, in another scenario, the display device is in the current channel (channel 2), channel 1 is the normal channel, the program content of the current channel is obtained, and after receiving the selection instruction for the current channel, first determine Whether the current channel is in a locked state, and if it is determined that the current channel is in an unlocked state, the program content of the current channel will continue to be played, so that on the user side, there will be no lags, black screens, etc. that interfere with the user's normal viewing. Improves the user’s viewing experience.

Then, the first authority parameter is used to filter the multiple candidate channels to obtain the target channel, which may be at least one of the following: in Hidden digital modulation channels, visible digital modulation channels, hidden analog modulation channels, and visible analog modulation channels.

For example, if the signal type parameter indicated by the target search signal option is an analog modulated signal parameter, and the second permission parameter indicated by the target channel permission option indicates that the channel is visible, it means that the user wishes to search for a visible analog channel. First, according to the analog modulated signal Parameters are used to perform a channel search to obtain multiple analog channels as candidate channels, and then the second permission parameter is used to find the permission flags in the channel information of multiple analog channels. If the permission flag in the channel information of an analog channel is 1, it means If the analog channel is a visible channel, then the analog channel is determined as a target channel, and all candidate channels are traversed to obtain a visible analog channel that meets the user's needs.

Figure 11 is a schematic diagram of a search mode setting interface provided in an embodiment of the present disclosure. The search mode setting interface 201 shown in Figure 11 is configured with a logical switch 14 to obtain logical channel information. When the logical switch 14 is turned on When the logic switch 14 is closed, the logical channel information indicates that the target channels do not need to be logically sorted. Further, if the logical channel information indicates logical sorting of the target channels, the target channels are sorted in order from large to small or from small to large according to the logical channel numbers (Logical Channel Number, LCN) obtained after parsing the target channels. Among them, LCN is used for program sorting and grouping in the field of digital television.

In summary, some embodiments of the present disclosure provide a channel search method, which displays a search mode setting interface.

In addition, in the current scenario where a user uses a display device to switch from a normal channel to a locked channel, when the display device has already displayed the password input interface, there may be a situation where the user accidentally exits the password input interface. If the user wants to exit the password input interface again, To bring up the password input interface, you need to first switch from the currently selected locked channel to another channel based on the channel switching logic, and then switch back to the locked channel before the password input interface can be redisplayed. This causes the user to have poor flexibility in the switching process related to the locked channel and affects the user experience. In some embodiments of the present disclosure, some processing steps are also provided to solve the above problem.

As shown in Figure 12, Figure 12 is a corresponding flow diagram provided by some embodiments of the present disclosure, including steps S1201 to S1204:

Among them, the program content of the current channel includes audio, video, image and other media resource content.

In some embodiments of the present disclosure, when the display device is in the current channel, it obtains the program content of the current channel, receives a channel switching instruction, the channel switching instruction is used to instruct switching from the current channel to the target channel, and the channel switching The instruction includes a first identifier of the target channel. The first identification includes at least one of the following: a channel name of the target channel, a channel type of the target channel, a channel number of the target channel, and a channel number of the target channel.

In some embodiments of the present disclosure, the above channel switching instruction can be generated based on the user's operation of selecting the current channel in the channel list, or can be generated based on the user inputting the identification of the current channel through a control device (such as a remote control), or can be generated The identification of the current channel is generated based on the user's voice input. The identification includes but is not limited to channel number (for example, 2.11) and channel name (for example, channel 1, news channel, CCTV13, etc.).

After receiving the above channel switching instruction, compare the first identifier of the target channel with the second identifier of the current channel, where the second identifier includes at least one of the following: channel name of the current channel, channel type of the current channel, The channel number of the current channel, the channel number of the current channel. For example, if the first identifier includes the channel name of the target channel and the channel number of the target channel, and the second identifier includes the channel name of the current channel and the channel number of the current channel, then the channel name of the target channel in the first identifier and the channel number of the current channel The channel names of the current channels in the two identifiers are compared, and the channel number of the target channel in the first identifier is compared with the channel number of the current channel in the second identifier.

If the first identifier and the second identifier match, it is determined that the channel switching instruction is a selection instruction of the current channel. If the first identifier and the second identifier do not match, it means that the user desires to switch to a target channel different from the current channel, and the display device performs the operation indicated by the channel switching instruction.

In a certain embodiment of the present disclosure, as shown in Figure 13A, Figure 13A is a schematic diagram of a channel switching instruction provided by an embodiment of the present disclosure. When the display device is in the current channel 2.11, the user presses the If the confirmation key is pressed, the remote controller sends a channel switching instruction to the display device, and the display device determines that the selection instruction is a selection instruction for the current channel 2.11, indicating that the user desires to switch to the current channel 2.11.

In a certain embodiment of the present disclosure, as shown in Figure 13B, Figure 13B is a schematic diagram 2 of a channel switching instruction provided by an embodiment of the present disclosure. When the display device is in the current channel 2.12, the user operates the display device through the remote control. Call up the channel search interface 71, and input the channel number: 2.12 in the channel search interface 71 through the remote control. After confirming the search, a selection instruction for the current channel 2.12 is generated, indicating that the user desires to switch to the current channel 2.12.

In a certain embodiment of the present disclosure, as shown in Figure 13C, Figure 13C is a schematic diagram 3 of a channel switching instruction provided by an embodiment of the present disclosure. When the display device is in the current channel 2.12, the user operates the display through the remote control to wake up. Exit the voice input interface 72 and say "switch to channel 2.13". The display device obtains the user's input in the voice input interface 72. After receiving the input voice, it is determined that the voice corresponds to a channel switching instruction. The channel switching instruction is used to instruct switching from the current channel 2.12 to the channel 2.13.

The above-mentioned manner in which the display device obtains the selection instruction for the current channel is only an exemplary description, and the present disclosure does not limit this.

After comparing the first identification of the target channel with the second identification of the current channel, if the first identification and the second identification match, it is determined that the channel switching instruction is a selection instruction of the current channel, and then the selection instruction for the current channel is responded to , determine whether the current channel is locked.

It should be noted that the display device determines whether the current channel is in a locked state by querying whether the current channel is locked. Locking refers to the password lock (such as parental lock) function provided by the display device. The user sets a password for the channel that is expected to be locked. Lock to store the password information corresponding to the channel in the display device. When users watch this locked channel through a display device, they need to enter a password to unlock it. The locking form of the password lock can be a combination of numbers, characters, and symbols, a gesture lock, or a biometric information lock. For example, the user uses fingerprint information and voiceprint information to lock the channel. This disclosure does not limit this. When the user sets a password lock for a channel that is desired to be locked, the user can also set the lock end time for locking the channel, so that the channel is in a locked state from the time when the password lock is set to the lock end time; for example, set If the password lock time is 7:00 and the lock end time is 11:30, then the channel is locked from 7:00 to 11:30 and viewing is not supported; alternatively, set the lock time for the channel. Lock time period, you can freely set the time in the locked state. For example, if you set the lock time period to 22:00-6:00, then the channel does not support viewing during the 22:00-6:00 time period.

After comparing the first identifier of the target channel with the second identifier of the current channel, if the first identifier and the second identifier do not match, it means that the user desires to switch to a target channel that is different from the current channel, and then obtain the program content of the target channel. , then switch from the current channel to the target channel, and determine whether the target channel is in a locked state. When the target channel is in an unlocked state, control the display to display the program content of the target channel. When the target channel is in an unlocked state, control the display to display the password input interface, and then obtain the unlock input for the password input interface, and determine the password information corresponding to the unlock input to unlock the target channel based on the password information. After unlocking the target channel Control the display to display the program content of the target channel.

In a certain embodiment of the present disclosure, as shown in Figure 14, Figure 14 is a schematic diagram of responding to a channel switching instruction provided by an embodiment of the present disclosure. The channel switching instruction received by the display device is used to indicate switching from the current channel 2.12 to Target channel 2.13. The display device responds to the channel switching command and determines that the first identifier of the target channel: 2.13 does not match the second identifier of the current channel: 2.12. Then it obtains the program content of the target channel 2.13 and switches from the current channel 2.12 to the target channel. Channel 2.13, and when it is determined that the target channel 2.13 is in the unlocked state, the display is controlled to play the program content of the target channel 2.13 in the video display area 16.

In some embodiments of the present disclosure, in response to the selection instruction for the current channel, in the process of determining whether the current channel is in a locked state, query whether the current channel has corresponding locking information, where the locking information may include a preset Password and locking end time or locking time period.

When the locking information of the current channel is obtained, if it is determined that the locking information includes the locking termination time, the current time is compared with the locking termination time. When the current time is less than the locking termination time, it is determined that the current channel is in the locked state; when the current time is greater than or equal to the locking termination time, it is determined that the current channel is in the unlocked state.
