Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

Channels for display devices can be classified into two types, one is an encrypted channel and the other is a normal channel. At present, some inelegant information such as sex, violence, inelegant words and the like may exist in the display content of a display device (such as a smart television), and the inelegant information may cause adverse effects on minors. For this reason, the display device usually provides a password lock function, which not only locks the program itself containing the inelegant information and prohibits the User from viewing, but also locks the program information (such as the program name and the playing time of the program) and does not display it on the User Interface (UI). The locked channel is called an encrypted channel, the normal channel is not encrypted, and the user can directly watch the program content of the normal channel without inputting a password.

In the related art, switching between a normal channel and an encrypted channel and switching between a normal channel and a normal channel are supported. In a scene of switching from a normal channel to an encrypted channel, a controller of a display device first determines that a channel to be switched is an encrypted channel and acquires program content of a decrypted channel, but the program content of the encrypted channel is not immediately displayed due to channel encryption, and the controller controls a password input interface to be displayed, as shown in fig. 1A, fig. 1A is a schematic diagram of the password input interface, and a display 260 of a display device 200 shown in the figure includes a channel list 10, a video display area 11 and a password input interface 12, and a user can input password information for the password input interface 12 to unlock the password channel.

In the case that the display device has already displayed the password input interface, there may be a case that the user mistakenly touches and exits the password input interface, at this time, the user interface of the display device is as shown in fig. 1B, and fig. 1B is a display schematic diagram after exiting the password input interface in the prior art. The display 260 of the display device 200 shown in the figure comprises a channel list 10 and a video presentation area 11, wherein an occlusion element 21 is present in the video presentation area 11 to prompt the user that the current channel is an encrypted channel and the video and audio contained in the program content of the encrypted channel are not output, which can be understood as that the video presentation area 11 is a blank interface. The user selects the encrypted channel again and the user interface of the display device remains as shown in fig. 1B.

If the password input interface is to be called again, the password input interface can be displayed again only by switching from the currently selected encrypted channel to another channel based on the channel switching logic and then switching back to the password channel. The method is complex to operate, the flexibility of channel switching is poor, and the use experience of a user is influenced.

The inventor finds that the existing channel switching logic does not support the logic for switching the same channel, so that the current channel is not switched to the current channel from the current encrypted channel in response to the instruction for selecting the current encrypted channel again when the encryption channel exists and the password input interface exits.

In order to solve the above technical problem, an embodiment of the present disclosure provides a display device and a channel switching method, where the display device obtains program content of a current channel through a controller when the display device is in the current channel, and responds to a selection instruction for the current channel to perform an operation of re-entering the current channel; when the current channel is re-entered in response to the selection instruction, whether the current channel is in an encrypted state or not is determined, the display is controlled to display the password input interface under the condition that the current channel is in the encrypted state, the unlocking input aiming at the password input interface is further acquired, the password information corresponding to the unlocking input is determined, then the current channel is unlocked according to the password information, the display is controlled to play the program content of the current channel, the requirements that a user already exists in the current channel and the current channel is in the encrypted state, the password input interface is re-called out and the unlocking is carried out are met, the user only needs to re-select the current channel, the operation is simple and convenient, the logic for switching aiming at the same channel is improved, and the flexibility of channel switching is improved.

The channel switching method provided by the embodiment of the disclosure can be implemented based on the display device, and specifically can be implemented by a player in the display device.

For more detailed description of the present solution, the following description is made in conjunction with fig. 6, and it is understood that the steps involved in fig. 6 may include more steps or fewer steps in actual implementation, and the order between the steps may also be different, so as to enable the channel switching method provided in the embodiment of the present disclosure.

As shown in fig. 6, fig. 6 is a schematic flow chart of a channel switching method according to an embodiment of the present disclosure, where the method includes steps S601 to S604:

s601, under the condition of the current channel, acquiring the program content of the current channel, and responding to the selection instruction aiming at the current channel to determine whether the current channel is in an encrypted state.

The program content of the current channel includes media resource content such as audio, video, image, etc.

In some embodiments, the display device obtains program content of a current channel when the display device is in the current channel, and receives a channel switching instruction, where the channel switching instruction is used to instruct to switch from the current channel to a target channel, and the channel switching instruction includes a first identifier of the target channel. Wherein the first identifier comprises at least one of the following items: a channel name of the target channel, a channel type of the target channel, a channel number of the target channel.

In some embodiments, the channel switching instruction may be generated according to an operation of the user selecting a current channel in the channel list, or may be generated according to an identifier of the current channel input by the user through a control device (e.g., a remote controller), or may be generated according to an identifier of the current channel input by the user through voice, where the identifier includes, but is not limited to, a channel number (e.g., 2.11) and a channel name.

After receiving the channel switching instruction, comparing a first identifier of the target channel with a second identifier of the current channel, wherein the second identifier comprises at least one of the following items: the channel name of the current channel, the channel type of the current channel, the channel number of the current channel, and the channel number of the current channel. For example, the first identifier includes a channel name of a target channel and a channel number of the target channel, and the second identifier includes a channel name of a current channel and a channel number of the current channel, the channel name of the target channel in the first identifier is compared with the channel name of the current channel in the second identifier, 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.

And if the first identifier is matched with the second identifier, determining that the channel switching instruction is a selection instruction of the current channel. And if the first identifier and the second identifier are not matched, the user desires to switch to a target channel different from the current channel, and the display equipment executes the operation indicated by the channel switching instruction.

For example, as shown in fig. 7A, fig. 7A is a schematic diagram of a channel switching instruction provided in the embodiment of the present disclosure, that is, in a case that the display device is in the current channel 2.11, if a user presses a confirmation key on a remote controller, the remote controller sends the 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, which indicates that the user desires to switch to the current channel 2.11.

For example, as shown in fig. 7B, fig. 7B is a schematic diagram of a channel switching instruction provided by the embodiment of the present disclosure, in a case that the display device is in the current channel 2.12, the user calls the channel search interface 71 by operating the display device through the remote controller, and inputs a channel number in the channel search interface 71 through the remote controller: and 2.12, after the search is confirmed, generating a selection instruction aiming at the current channel 2.12, and indicating that the user desires to switch to the current channel 2.12.

For example, as shown in fig. 7C, fig. 7C is a third schematic view of a channel switching instruction provided in the embodiment of the present disclosure, when the display device is in the current channel 2.12, the user invokes the voice input interface 72 by operating the display through the remote controller, and says "switch to channel 2.13", after the display device acquires the voice input by the user on the voice input interface 72, it is determined that the voice corresponds to the channel switching instruction, and the channel switching instruction is used for instructing to switch from the current channel 2.12 to the channel 2.13.

The manner in which the display device obtains the selection instruction for the current channel is merely an exemplary illustration, and the disclosure does not limit this.

After comparing the first identifier of the target channel with the second identifier of the current channel, if the first identifier is matched with the second identifier, determining that the channel switching instruction is a selection instruction of the current channel, and further responding to the selection instruction of the current channel to determine whether the current channel is in an encrypted state.

It should be noted that, the display device determines whether the current channel is in an encrypted state by querying whether the current channel is locked, where locking is a function of a coded lock (parental lock) provided by the display device, and a user sets the coded lock for a channel desired to be locked, so as to store coded information corresponding to the channel in the display device. When the user watches the locked channel through the display device, the user needs to input a password for decryption. The encryption form of the coded lock can be digital, character and symbol combination encryption, gesture encryption, and biometric information encryption, such as channel encryption by fingerprint information and voiceprint information of a user. The present disclosure is not limited thereto. When a user sets a password lock for a channel which is expected to be locked, the encryption termination time for encrypting the channel can be set, so that the channel is in an encryption state from the time when the password lock is set to the encryption termination time; for example, if the time of setting the combination lock is 7 00 and the time of ending encryption is 11, then the channel is in the encrypted state from 7; or, an encryption period for encrypting the channel is set to freely set the time in the encrypted state, for example, the encryption period is set to 22.

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 are not matched, the user desires to switch to a target channel different from the current channel, the program content of the target channel is acquired, then the current channel is switched to the target channel, whether the target channel is in an encrypted state or not is determined, and the display is controlled to display the program content of the target channel under the condition that the target channel is in a decrypted state. And under the condition that the target channel is in a decryption state, controlling the display to display a password input interface, further acquiring unlocking input aiming at the password input interface, determining password information corresponding to the unlocking input, unlocking the target channel according to the password information, and controlling the display to display the program content of the target channel after the target channel is unlocked.

Exemplarily, as shown in fig. 8, fig. 8 is a schematic diagram of responding to a channel switching instruction provided by an embodiment of the present disclosure, where the channel switching instruction received by the display device is used to instruct to switch from the current channel 2.12 to the target channel 2.13, and the display device determines, in response to the channel switching instruction, a first identifier of the target channel: 2.13 and second identification of current channel: 2.12, the program content of the target channel 2.13 is obtained, the current channel 2.12 is switched to the target channel 2.13, and the display is controlled to play the program content of the target channel 2.13 in the video display area 11 if the target channel 2.13 is determined to be in the decrypted state.

In some embodiments, in the process of determining whether the current channel is in an encrypted state in response to the selection instruction for the current channel, whether corresponding encryption information exists in the current channel is queried, wherein the encryption information may include a preset password and an encryption termination time or an encryption time period.

Under the condition of acquiring the encryption information of the current channel, if the encryption information comprises the encryption termination time, comparing the current time with the encryption termination time. Determining that the current channel is in an encryption state under the condition that the current time is less than the encryption termination time; and determining that the current channel is in a decryption state when the current time is greater than or equal to the encryption termination time.

Illustratively, the encryption information of the current channel 2.11 acquired by the display device includes an encryption termination time 11.

Under the condition of acquiring the encryption information of the current channel, if the encryption information comprises an encryption time period, determining whether the current time is in the encryption time period, and if the current time is in the encryption time period, determining that the current channel is in an encryption state; and if the current time exceeds the encryption time period, determining that the current channel is in a decryption state.

For example, the encryption information of the current channel 2.11 acquired by the display device includes an encryption time period 22-00, and if the current time is 10.
