[0034] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0035] Combination Figure 1 As shown, an embodiment of the present disclosure provides a response method for a display device, which is applied to a set-top box. The method includes:

[0036] S01: Obtain working status information of a display device.

[0037] S02: If the working status information indicates that the display device is in a standby state, a first broadcast signal is acquired.

[0038] S03: Determine whether the target feature of the first broadcast signal matches the first preset signal feature; if they match, execute S04.

[0039] S04: Control the display device to switch from the standby state to the power-on state.

[0040] S05: Sending the target feature of the first broadcast signal to the display device to perform a broadcast prompt through the display device.

[0041] Among them, display devices include household electronic devices with display functions such as televisions, computers, tablets, and smart homes. This application does not make specific restrictions on this. The power-on control device includes pluggable devices and electronic devices such as remote controls that can communicate with display devices at close range. As an example, pluggable devices include software dongles (Software Dongle) and USB (universal serial bus) disks. As another example, the remote control includes an infrared remote control or a Bluetooth remote control. This application does not make specific restrictions on this.

[0042] Using the response method for a display device provided by an embodiment of the present disclosure, a set-top box obtains the working status information of the display device. If the working status signal indicates that the display device is in a standby state, a first broadcast signal is obtained. If the first broadcast signal matches the first preset signal feature, it indicates that an emergency broadcast signal has been received. At this time, the set-top box controls the display device to switch from a standby state to a powered-on state, and sends the target feature of the first broadcast signal to the display device to broadcast prompts through the display device. The executor of the method is a set-top box. After determining that the display device is in a standby state, the set-top box determines that an emergency broadcast signal is received. If an emergency broadcast signal is received, the display device is switched to a powered-on state and prompts are broadcast through the display device. The method enables the set-top box to switch a television set in a standby state to a powered-on state and broadcast prompts when receiving an emergency broadcast signal, thereby expanding the response range of the television set.

[0043] Optionally, controlling the display device to switch from a standby state to a power-on state includes:

[0044] Send a power-on control signal to the display device to wake up the display device to a power-on state.

[0045] The power-on control signal is an infrared control signal or a Bluetooth control signal.

[0046] In this way, the state of the display device can be switched by sending an infrared control signal or a Bluetooth control signal to the display device, so that the display device is turned on to perform a broadcast prompt.

[0047] Optionally, the display device sends prompt information to the user to implement broadcast prompts. The prompt information includes one or more of voice, image, video or text. In this way, broadcast prompts can be intuitively provided to the user.

[0048] Optionally, the target feature of the first broadcast signal is the designated frequency of the first broadcast signal. The first preset signal feature is the designated frequency of the first emergency broadcast signal. In this way, when the designated frequency of the first broadcast signal matches the designated frequency of the first emergency broadcast signal, it can be determined that the set-top box has received the emergency broadcast signal. As an example, the designated frequency of the first broadcast signal is equal to the designated frequency of the first emergency broadcast signal; or, the designated frequency of the first broadcast signal is within a first preset range; wherein the first preset range is a frequency band centered on the designated frequency of the first emergency broadcast signal. This application does not make any specific limitations on this.

[0049] Combination Figure 2 As shown, the embodiment of the present disclosure also provides a response method for a display device, and the display device is also configured with a power-on control device. The method includes:

[0050] S11: Obtaining working status information of the display device.

[0051] S12: If the working state information indicates that the display device is in a standby state, a first broadcast signal is acquired.

[0052] S13: Determine whether the target feature of the first broadcast signal matches the first preset signal feature; if so, execute S14; if not, execute S16.

[0053] S14: Control the display device to switch from the standby state to the power-on state.

[0054] S15: Sending the target feature of the first broadcast signal to the display device to perform a broadcast prompt through the display device.

[0055] S16: Triggering the power-on control device to control the display device to power on.

[0056] By adopting the response method for a display device provided in an embodiment of the present disclosure, when the target feature of the first broadcast signal does not match the first preset signal feature, the power-on control device can be triggered to perform power-on control on the display device, thereby adding a detection path for emergency broadcast signals. If an operation abnormality occurs in the set-top box or the power-on control device, or an associated power supply abnormality occurs in the set-top box or the power-on control device, the emergency broadcast signal can be detected by a device with no abnormal operation / power supply, thereby improving the efficiency of detection.

[0057] Optionally, the working state information of the display device includes a standby broadcast signal. In this way, the display device sends the information in the form of a broadcast signal to a set-top box and / or a power-on control device associated with the display device, so that the set-top box and / or the power-on control device associated with the display device can obtain the working state of the display device in a timely manner.

[0058] Combination Figure 3 As shown, the embodiment of the present disclosure also provides a response method for a display device, which is applied to a power-on control device. The method includes:

[0059] S21: Obtain a trigger signal sent by a set-top box associated with the display device, where the trigger signal is sent to the power-on control device when the set-top box determines that a target feature of the first broadcast signal does not match a first preset signal feature.

[0060] S22: If the second broadcast signal is acquired, determine whether the target feature of the second broadcast signal matches the second preset signal feature; if they match, execute S23.

[0061] S23: Control the display device to switch from the standby state to the on state. The first broadcast signal and the second broadcast signal are different types of broadcast signals.

[0062] S24: Sending the target feature of the second broadcast signal to the display device to perform a broadcast prompt through the display device.

[0063] Using the response method for a display device provided by an embodiment of the present disclosure, when the target characteristic of the first broadcast signal obtained by the set-top box does not match the first preset signal characteristic, the second broadcast signal is obtained through the power-on control device, and when the target characteristic of the second broadcast signal matches the second preset signal characteristic, the display device is controlled to switch from the standby state to the power-on state, and the target characteristic of the second broadcast signal is sent to the display device to broadcast prompts through the display device. This method increases the detection path of the emergency broadcast signal and further improves the detection efficiency. In addition, since the first broadcast signal and the second broadcast signal are different types of broadcast signals, and different types of broadcast signals are associated with different frequency bands, the display device can obtain broadcast signals from two different frequency bands, and the accuracy of the response is higher.

[0064] The target feature of the second broadcast signal is the designated frequency of the second broadcast signal. The second preset signal feature is the designated frequency of the second emergency broadcast signal. In this way, when the designated frequency of the second broadcast signal matches the designated frequency of the second emergency broadcast signal, it can be determined that the set-top box has received the emergency broadcast signal. As an example, the designated frequency of the second broadcast signal is equal to the designated frequency of the second emergency broadcast signal; or, the designated frequency of the second broadcast signal is within a second preset range; wherein the second preset range is a frequency band centered on the designated frequency of the second emergency broadcast signal. This application does not make specific limitations on this.

[0065] Combination Figure 3 As shown, the embodiment of the present disclosure also provides a response method for a display device, which is applied to a power-on control device. The method includes:

[0066] S31: Obtain a trigger signal sent by a set-top box associated with the display device, where the trigger signal is sent to the power-on control device when the set-top box determines that a target feature of a first broadcast signal does not match a first preset signal feature.

[0067] S32: If the second broadcast signal is acquired, determine whether the target feature of the second broadcast signal matches the second preset signal feature; if so, execute S33; if not, execute S35.

[0068] S33: Control the display device to switch from the standby state to the on state. The first broadcast signal and the second broadcast signal are different types of broadcast signals.

[0069] S34: Sending the target feature of the second broadcast signal to the display device to perform a broadcast prompt through the display device.

[0070] S35: triggering the set-top box to reacquire the new first broadcast signal, so that the set-top box controls the display device to turn on according to the new first broadcast signal.

[0071] By adopting the response method for display devices provided by the embodiment of the present disclosure, when the target feature of the second broadcast signal acquired by the power-on control device does not match the second preset signal feature, the set-top box is triggered to reacquire the new first broadcast signal, so that the set-top box performs power-on control on the display device according to the new first broadcast signal. The method enables the step of powering on the display device to be alternately executed between the set-top box and the power-on control device, and each performs emergency broadcast signal detection through different frequency bands, which has good real-time performance and improves the accuracy of detection.

[0072] Optionally, the first broadcast signal is a digital video broadcast signal, and the second broadcast signal is a digital television terrestrial broadcast signal. In this way, the television usually receives digital video broadcasts through a set-top box and receives digital television terrestrial broadcasts through an external device, and the emergency broadcast signal may be transmitted to the television through the set-top box or through an external device associated with the television. Therefore, in the case where the target feature of the first broadcast signal fails to match the first preset signal feature through the set-top box, the target feature of the second broadcast signal is matched with the second preset signal feature through the power-on control device, thereby further improving the accuracy of the detection.

[0073] Optionally, the first broadcast signal is a digital television terrestrial broadcast signal, and the second broadcast signal is a digital video broadcast signal.

[0074] The embodiment of the present disclosure also provides a response system for a display device, including a set-top box associated with the display device. The set-top box obtains working status information of the display device, and if the working status information indicates that the display device is in a standby state, obtains a first digital broadcast signal. If the target feature of the first broadcast signal matches the first preset signal feature, the display device is controlled to switch from the standby state to the power-on state, and the target feature of the first digital broadcast signal is sent to the display device, so as to broadcast a prompt through the display device.

[0075] Using the response system for display devices provided by the embodiment of the present disclosure, the set-top box obtains the working status information of the display device. If the working status signal indicates that the display device is in a standby state, the first broadcast signal is obtained. If the first broadcast signal matches the first preset signal feature, it indicates that an emergency broadcast signal has been received. At this time, the set-top box controls the display device to switch from a standby state to a powered-on state, and sends the target feature of the first broadcast signal to the display device to broadcast prompts through the display device. The executor of the method is a set-top box. After determining that the display device is in a standby state, the set-top box determines that an emergency broadcast signal is received. If an emergency broadcast signal is received, the display device is switched to a powered-on state and prompts are broadcast through the display device. The system enables the set-top box to switch a television set in a standby state to a powered-on state and broadcast prompts when receiving an emergency broadcast signal, thereby expanding the response range of the television set.

[0076] The disclosed embodiment also provides a response system for a display device, including a set-top box and a power-on control device associated with the display device. The power-on control device obtains a trigger signal sent by the set-top box associated with the display device, and the trigger signal is sent to the power-on control device when the set-top box determines that the target feature of the first broadcast signal does not match the first preset signal feature. If the power-on control device obtains a second broadcast signal, and the target feature of the second broadcast signal matches the second preset signal feature, the display device is controlled to switch from a standby state to a power-on state. The first broadcast signal and the second broadcast signal are different types of broadcast signals. The target feature of the second broadcast signal is sent to the display device to perform a broadcast prompt through the display device.

[0077] Using the response system for a display device provided by an embodiment of the present disclosure, when the target feature of the first broadcast signal obtained by the set-top box does not match the first preset signal feature, the set-top box sends a trigger signal to obtain the second broadcast signal through the power-on control device, and when the target feature of the second broadcast signal matches the second preset signal feature, the display device is controlled to switch from the standby state to the power-on state, and the target feature of the second broadcast signal is sent to the display device to broadcast prompts through the display device. The system adds a detection path for emergency broadcast signals, further improving the detection efficiency. In addition, since the first broadcast signal and the second broadcast signal are different types of broadcast signals, and different types of broadcast signals are associated with different frequency bands, the display device can obtain broadcast signals from two different frequency bands, and the accuracy of the response is higher.

[0078] In practical applications (such as Figure 4 As shown in FIG. 1 , the display device is a television. The power-on control device is a software dog plugged into the television. The set-top box is connected to the television via a communication line.

[0088] S49: The power-on control device sends the target characteristics of the target digital television terrestrial broadcast signal to the television set, so as to provide a broadcast prompt through the television set.

[0089] S50: The power-on control device triggers the set-top box to reacquire the new target digital video broadcast signal, so that the set-top box controls the power-on of the television according to the new target digital video broadcast signal.
