For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
With the rapid development of intelligent televisions, the functions and the characteristics of the televisions are greatly improved. The conventional television can only receive cable television signals or wireless television signals through an antenna, and a user can watch different programs only by switching channels through a remote controller. However, with the popularity of smart televisions, the sources of television sets have also become diversified and multiple-input. In addition to conventional television signals, users may connect various external devices, such as a set-top box, a game machine, a DVD player, etc., through HDMI to obtain more entertainment content.
However, there is a concomitant problem with source selection. In the past, users only need to switch channels through a television remote controller, but now users need to select correct information sources by using the television remote controller firstly and then select programs by using a remote controller of external equipment (such as a set top box). In addition, when selecting the source, the user does not know which source interface is currently used by the television, and the user needs to operate and switch the source for multiple times to match the source of the television with the currently used source interface. The operation mode is complicated, inconvenience is brought to the user, and the use experience of the user is greatly influenced.
In this regard, the embodiment of the invention provides a method for switching information sources, which can enable a user to realize a one-key rapid switching function through remote control equipment, switch the information sources of a display to target information sources, is simple and convenient to operate, does not need the user to switch for multiple operations, and improves user experience, thereby overcoming the defects.
It should be noted that the remote control device refers to a wireless remote controller or a remote control device for remotely controlling other devices, for example, the remote control device may be a television remote controller, a set-top box remote controller, or other electronic devices with remote control functions. A display refers to a device for displaying images or video, such as a television, a computer display, etc. The target source refers to an external device to which the display is connected, such as a set-top box of a television set, etc. In the embodiment of the invention, the television is taken as an example for carrying out information source switching, and in the scene, the remote control equipment can be a television remote controller, the display is the television, and the target information source can be a set top box.
Fig. 1 is a schematic flow chart of a source switching method provided by the present invention, as shown in fig. 1, the method is applied to a remote control device, and the method includes:
step 110, receiving a switching input;
Step 120, in response to the switching input, respectively sending a source switching instruction to the display and the target source to trigger the display to poll the switching source, and trigger the target source to adjust the signal output to the display to a signal carrying the equipment identifier;
specifically, the switching input refers to an input operation performed by a user on the remote control device to perform a function of sending a source switching instruction, for example, a source switching key may be disposed on the remote control device, and the user may implement the switching input by clicking the source switching key on the remote control device.
The remote control device may establish a communication connection with the display and the target source to send a source switch command, where the communication connection may be via transmission of wireless signals, such as bluetooth communications, infrared, radio frequency, etc. After detecting the switching input, the remote control device sends a source switching instruction to the display and the target source respectively through a wireless communication mode, wherein the source switching instruction can be a specific code or a data packet generated by the remote control device.
The display and the target source have corresponding receivers for receiving and decoding the source switching instruction, and the display can start to poll the switching source after receiving the source switching instruction. Here, polling the switching source refers to that after receiving the source switching instruction, the display sequentially switches to different sources according to a certain sequence, and the sequence can be preset or user-defined. By polling the switching sources, the display may sequentially try different input signals to find the target source that the user wishes to switch.
For example, after receiving the source switching command, the television may sequentially switch to different input sources according to a preset source switching sequence, for example, the television may perform polling switching according to the sequence of HDMI, AV, VGA. The television can integrate a signal switching module inside, can detect the input signals of different input interfaces, after receiving the signal source switching instruction, the television will detect different signal sources one by one through the signal switching module, and transmit the signal of the signal source to the display screen for display.
It will be appreciated that the target source may be wired to one source interface of the display via a signal data line (e.g., HDMI data line) to output signals to the display. And under the condition that the target information source receives the information source switching instruction, the output signal of the target information source is adjusted, namely, the signal output to the display is adjusted to be a signal carrying the equipment identifier. Here, the signal output to the display means a signal that the target source outputs to the display through the data line to display images and sounds on the display, and this signal may be content such as video, audio, image data, text data, and the like from the target source.
The signal carrying the device identifier refers to that the target information source adds device identifier information to the output signal, and the device identifier refers to a unique identification code or identifier for identifying the target information source, which may be a predefined device identifier code. The signal output to the display is adjusted to be the signal carrying the equipment identifier, so that the remote control equipment can correctly identify the target information source, and the information source of the display is switched to the target information source.
And 130, respectively sending a switching completion instruction to the display and the target information source to control the display to stop switching the information source and control the target information source to adjust a signal output to the display to a default signal under the condition that the information displayed by the display includes the equipment identifier.
Specifically, the information displayed by the display refers to information corresponding to the switched information source displayed on the screen during the process of polling the switched information source by the display. The display information may be images, text, audio, video, etc., which is not particularly limited in the embodiment of the present invention.
When the display polls and switches to the target information source, the display receives a signal which is output by the target information source and carries the equipment identifier, so that information corresponding to the signal can be displayed. For example, the information displayed by the display can be a two-dimensional code image, a corresponding image acquisition module can be arranged on the remote control device, and the target information source can be correctly identified by acquiring and detecting the two-dimensional code image displayed on the screen of the display. For another example, the information displayed by the display can be audio, and the remote control device is provided with a corresponding audio acquisition module, so that the target information source can be correctly identified by acquiring and detecting the audio played by the display.
The remote control device detects and identifies information displayed by the display, if the display information comprises a device identifier, the remote control device indicates that a signal corresponding to the display information is a signal output by a target information source, namely, the information source currently displayed by the display is the target information source, and at the moment, the remote control device can respectively send a switching completion instruction to the display and the target information source so as to finish the information source switching process.
After receiving the switching completion instruction, the display stops switching the information source. After receiving the switching completion instruction, the target information source restores the signal output to the display to a default signal, so that the display can play corresponding content based on the default signal. Here, the handover complete instruction refers to an instruction sent by the remote control device to the display and the target source for informing them that the source handover operation has been completed. The default signal refers to a signal that the target signal source outputs to the display through the data line to display images and sounds on the display under the condition that the signal source switching instruction is not received, for example, the default signal may be a high-quality audio/video signal transmitted to the television by the set top box, so that the television can play corresponding program content.
By way of example, the set top box may be connected to a television via HDMI to transmit high quality audio and video signals to the television, so that a user may obtain a rich and varied entertainment content, and enhance the television viewing experience. In order to conveniently and rapidly switch the signal source of the television to the set top box, a signal source switching key can be arranged on a television remote controller, after a user presses the signal source switching key, the television remote controller respectively sends a signal source switching instruction to the television and the set top box, after receiving the signal source switching instruction, the television starts to poll and switch the signal source, displays information corresponding to the switched signal source, and after receiving the signal source switching instruction, the set top box adjusts a signal output to the television to a signal carrying a device identifier. The television remote controller can be provided with a camera, in the process of switching the information sources through the television polling, the television remote controller can acquire information displayed by the television through the camera and detect and identify the displayed information, under the condition that the television remote controller detects that the displayed information comprises equipment identifiers, the television remote controller respectively sends switching completion instructions to the television and the set top box, after receiving the switching completion instructions, the television stops switching the information sources, and after receiving the switching completion instructions, the set top box restores signals output to the television to default signals, so that the information sources of the television are switched to target information sources. In the embodiment of the invention, the user can switch the information source of the television to the target information source by only pressing the information source switching key on the television remote controller, and the operation is simple and quick.
Further, the display itself is usually built with a source, and after receiving the switching input, the remote control device not only can switch the source of the display from the source to the target source, but also can switch the source of the display from the target source back to the source. For example, the television remote controller can realize the function of switching the signal source quickly by one key through the signal source switching key, and can quickly switch between the television signal source and the signal source of the set top box, wherein the television signal source is the signal source built in the television. After a user presses a source switching key on a television remote controller, the television can be switched from a television mode to a set top box mode, and meanwhile, the television can store state information of the television mode, so that when the user presses the source switching key again, the television can return to the previous television mode. It should be understood that the above-mentioned television mode refers to an operating state in which the television receives and displays a broadcast television signal (i.e., a built-in signal source of the television itself), and the set-top box mode refers to an operating state in which the television receives and displays a set-top box signal. In the embodiment of the invention, the user can realize the function of switching the information source by one key through the information source switching key, so that the user can conveniently switch from the television mode to the set top box mode and also conveniently switch from the set top box mode to the television mode, and can conveniently and rapidly select the desired information source, thereby improving the user experience.
According to the method provided by the embodiment of the invention, the information source switching instruction is respectively sent to the display and the target information source to trigger the display to poll the switching information source, the target information source is triggered to adjust the signal output to the display to the signal carrying the equipment identifier, the switching completion instruction is respectively sent to the display and the target information source under the condition that the information displayed by the display is detected to comprise the equipment identifier, the display is controlled to stop switching the information source, and the target information source is controlled to adjust the signal output to the display to the default signal, so that the information source of the display is switched to the target information source, the operation is simple and convenient, the user does not need to operate the switching information source for multiple times, and the use experience of the user is greatly improved.
Based on the above embodiment, in step 130, in the case where the display information is an image, detecting that the information displayed on the display includes the device identifier includes:
acquiring an image displayed by a display;
performing identification detection on the image, and comparing the equipment identification with the identification obtained by detection;
under the condition of consistent comparison, determining that the information displayed by the display comprises equipment identification;
and in the case of inconsistent comparison, returning to acquire the image displayed by the display again.
Specifically, an image acquisition module, such as a camera, may be disposed on the remote control device, and the image displayed by the acquisition display is shot by the camera. After the image is acquired, the image may be subjected to identification detection, which is a computer vision task for identifying and locating a specific identification or object in the image.
When the image is identified and detected, the identification and detection method can be realized by adopting an identification and detection model based on deep learning, for example, a proper initial model can be selected, the initial model is trained through a collected image data set, a trained identification and detection model is obtained, after the image displayed by a display is obtained, the image can be input into the identification and detection model, and the image is identified and detected through the model, so that an identification and detection result output by the model, namely the identification obtained by detection, is obtained.
When the identification detection is carried out on the image, the two-dimensional code detection and decoding technology can be adopted. For example, in the case where the acquired image is a two-dimensional code image, the image may be preprocessed, such as gray-scale conversion, binarization, noise reduction, and the like, and then the preprocessed image may be detected using a method based on edge detection or feature extraction, and the detected two-dimensional code area may be decoded to acquire the device identification information therein.
After the detected identity is obtained, the identity may be compared with a device identity, which may be pre-stored in the remote control device. If the comparison is consistent, the information currently displayed by the display can be determined to comprise the equipment identifier, the information currently displayed by the display is indicated to be the target information source, and the information source switching operation can be ended at the moment; if the comparison is inconsistent, the information displayed at present does not comprise the equipment identification, namely the information source displayed at present by the display is not the target information source, at the moment, the display continues to poll and switch the information source, and meanwhile, the remote control equipment acquires the image displayed by the display again until the target information source is found.
According to the method provided by the embodiment of the invention, the target information source can be rapidly identified by collecting the image displayed by the display and carrying out identification detection on the image, so that the real-time information source switching is realized, and meanwhile, the efficiency and the accuracy of identifying the target information source are improved, thereby improving the user experience.
Based on the above embodiment, the image acquisition frequency is consistent with the frequency of the display switching source.
Specifically, the acquisition frequency of an image refers to the frequency of image acquisition, i.e., the number of times images are acquired per second. The frequency at which the display switches sources refers to the speed of the display when polling to switch different sources, i.e., the number of source switches per second.
In the embodiment of the invention, the acquisition frequency of the image is kept consistent with the frequency of the display switching information source, so that the remote control equipment can acquire the image and the display switching information source synchronously, the remote control equipment can acquire the image at a correct time point, the target information source can be accurately identified, and the accuracy and the stability of the identification of the target information source are improved.
Based on any of the above embodiments, in step 120, sending a source switching instruction to the display includes:
under the condition of storing the information source sequence number, sending an information source switching instruction carrying the information source sequence number to the display, and triggering the display to poll and switch the information source by taking the information source corresponding to the information source sequence number as a starting point;
the source sequence number is the sequence number of the source displayed after the last stop switch sent by the display.
It should be noted that, considering that in an actual scenario, the connection interface between the set top box and the television set is not frequently changed, in order to further improve the efficiency of source switching, the source of the television set is quickly switched to the set top box.
Specifically, the source sequence number refers to a number or serial number for identifying different sources, which is used to distinguish and identify different input sources, such as HDMI1, HDMI2, HDMI3, and the like. When the remote control device performs the source switching operation for the first time, the remote control device does not store the source serial number locally, at this time, if the user performs the source switching operation through the remote control device, the remote control device will send a common source switching instruction to the display, and after receiving the source switching instruction, the display may poll the switching source according to a preset source switching sequence, for example, may switch according to the sequence of HDMI1, HDMI2, and HDMI 3.
After the information source switching operation is carried out, the display can send the sequence number of the information source displayed after the switching is stopped to the remote control equipment for storage, so that the remote control equipment can acquire the locally stored information source sequence number when the information source switching operation is carried out next time. For example, when the source switching operation is performed, when the source is switched to the source with the serial number of HDMI2, the remote control device recognizes that the source is the target source, and sends a switching completion instruction to the display and the target source, and when the display receives the switching completion instruction, the display stops switching the source and sends the serial number of HDMI2 of the source to the remote control device for storage.
When the user performs the source switching operation through the remote control device again, the remote control device can acquire the locally stored source sequence number, and the source sequence number is added into the source switching instruction and sent to the display together. After receiving the information source switching instruction, the display can acquire the information source sequence number therein by analyzing the information source switching instruction, so that the information source corresponding to the information source sequence number can be used as a starting point for polling and switching the information source. For example, switching is performed in the order of HDMI2, HDMI3, HDMI 1.
It will be appreciated that the source switch instruction carrying the source sequence number is an instruction or command for sending a signal to the display informing the display to switch to the source with the specified sequence number. After receiving the information source switching instruction carrying the information source sequence number, the display can preferentially start polling and switching the information source from the appointed information source sequence number, and at the moment, if the remote control equipment detects that the information displayed by the display comprises the equipment identification, the information source displayed at present can be rapidly determined to be the target information source; if the remote control device does not detect that the information displayed by the display device comprises the device identification, the display device continues to poll the switching information source until the target information source is found.
According to the method provided by the embodiment of the invention, the remote control equipment can rapidly detect and identify the target information source by storing the information source sequence number and sending the information source switching instruction carrying the information source sequence number to the display, so that the information source switching efficiency is improved.
Based on any of the above embodiments, the method further comprises:
receiving a startup input, responding to the startup input, and respectively sending startup instructions to a display and a target information source;
or,
and receiving a shutdown input, and responding to the shutdown input, and respectively sending a shutdown instruction to the display and the target information source.
Specifically, the power-on input refers to an input operation performed by a user on a remote control device to perform a function of sending a power-on instruction, for example, a television remote control may be respectively connected with a television and a set-top box in a communication manner, a power key may be set on the television remote control, and the user may implement the power-on input operation by clicking the power key on the television remote control, where the power-on input is a signal generated after the user presses the power key, and is used to trigger the power-on operations of the television and the set-top box.
After the remote control device detects the startup input, the remote control device respectively sends startup instructions to the display and the target information source so as to realize the function of synchronously starting the display and the target information source. The power-on command refers to a command sent by the remote control device to the display and the target information source, and may be an infrared signal, a wireless signal or a command of other communication protocols. For example, when a user presses a power button on the television remote control, the television remote control sends a corresponding power-on command to the television and the set-top box to start their power-on operations.
