In the set-top box display device shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the set-top box display device of the present invention may be disposed in the set-top box display device, where the set-top box display device invokes the set-top box display program stored in the memory 1005 through the processor 1001, and executes the set-top box display method provided by the embodiment of the present invention.
The embodiment of the invention provides a set top box display method, referring to fig. 2, fig. 2 is a flow chart of a first embodiment of the set top box display method.
In this embodiment, the set top box display method includes the following steps:
step S10: and receiving voice information of the resource request, determining user permission according to the voice information, and carrying out identity authentication on the user permission to obtain an identity authentication result.
It should be noted that, the execution body of the embodiment is a set top box display device, where the set top box display device has functions of data processing, data communication, program running, etc., and the set top box display device may be an integrated controller, a control computer, etc., or may be other devices with similar functions, which is not limited in this embodiment.
It should be understood that the set top box has a function of turning on voice control, and when the voice control function is turned on, the set top box can be controlled by voice to acquire resource content from the cloud. Referring to fig. 3, fig. 3 is a connection manner of the set-top box. The set top box and the display terminal can be connected in a wired mode, such as HDMI mode, and the resource content can be transmitted in a wired mode or in a wireless local area network mode. In consideration of transmission quality and arrangement cost, the preferred connection mode of the embodiment is that the set top box is connected with one display terminal through a wire and is connected with other terminals through a wireless mode.
In a specific implementation, when the voice control function of the set top box is started, the user can wake up the set top box through a specific sentence, meanwhile, after receiving the wake-up sentence, the set top box can feed back a signal to the user, and the reminding modes such as change reminding of the indicator light, voice response reminding or combination of the two can be used, and the embodiment is not limited. After receiving feedback information of the set top box, a user can send out voice information of a resource request, wherein the voice information comprises resource content to be acquired, display terminal information for acquiring the resource content and the like, one voice information can contain multiple similar resource requests, for example, one voice information can contain three different resource requests, and the three resource requests are respectively transmitted to three display terminals for display. After speaking the voice information of the resource request, the set top box can verify the current user authority for the voice information when receiving the voice information of the resource request, and perform identity authentication according to the user authority, so as to obtain an identity verification result.
For a family, each family member may be assigned an identity authority, which may be accomplished by setting up a set top box, where the user authority may include content restrictions, content unlimited, etc., and the identity authentication is used to determine whether the user identity and the requested resource corresponds to the user authority. For example, a parent and a child are included in a household, where the parent may be set with user rights to content restrictions, and with children set with content restrictions, where the content restrictions include resource request content and usage time periods. Meanwhile, the set top box can also carry out self-defined labels for the connected display terminals, the label format is a text format, the text content is not limited, for example, the label format can be in the form of a 'television in baby room' or 'display equipment in living room', and the like, and the embodiment is not limited to the self-defined labels.
Step S20: and when the user authority identity authentication passes, extracting the request content in the voice information, and acquiring the resource content from the cloud according to the request content.
In a specific implementation, when the user authority identity authentication passes, the current resource request is required to be processed for the set top box. Therefore, the set top box needs to process the voice information, acquire the voice information from the voice information of the resource request, specifically can convert the voice information into text information, obtain the request information for performing the resource request through the text information, specifically can include target resource content, resource request equipment, the position of the target resource and the like, and can transmit the corresponding resource content to the corresponding set top box according to the request message through the resource request message to the cloud. The set top box can generate a similar function locally according to the voice information as follows: device a-resource 1; the method comprises the steps that text information such as equipment B-resource 2 is extracted by a set top box, a network IP address of the set top box is added, a message such as [ IP address-resource 1-resource 2..resource n ] is obtained and transmitted to a cloud end, the cloud end can extract resources to be queried according to the obtained message, the obtained resources are ordered according to the same sequence as the requested resources, a resource content set is obtained, and the obtained resource content set is fed back to the set top box according to the IP address carried in the message.
Step S30: and when the resource content corresponds to a plurality of display terminals, sending the resource content to the corresponding display terminals according to the resource content, so that the display terminals display the resource content.
In a specific implementation, the set top box can judge the number of display terminals in the current resource request and the labels of the display terminals corresponding to the resource content according to the voice information. When the current resource content corresponds to a plurality of display terminals, the set top box can send the resource content to the corresponding display terminal according to the corresponding relation between the resource in the resource request and the display terminal, so that the display terminal can display the received resource content. When one display terminal label corresponds to a plurality of resource contents, the content of each resource content can be mixed according to the frame sequence and then transmitted to the display terminal. For example, two resource contents may be transmitted in a manner of being arranged as ababab.
Further, in order to reduce the load of the set top box, to avoid that the set top box establishes a plurality of data transmission channels simultaneously to reduce the data processing efficiency, when the resource content corresponds to a plurality of display terminals, the resource content is sent to the corresponding display terminals according to the resource content, so that the display terminals display the resource content, including:
when the request content of a plurality of display terminals is the same, transmitting the resource content corresponding to the request content to a master display terminal, and forwarding the resource content to other slave display terminals by the master display terminal through a local area network, wherein the plurality of display terminals comprise the master display terminal and at least one slave display terminal.
When the set top box is connected to a plurality of display terminals at the same time, the display terminal connected to the set top box in a wired manner or the display terminal connected first may be determined as the master display terminal, and the other display terminals are slave display terminals.
In a specific implementation, when the main display terminal is in a start-up state, if a plurality of display terminal contents in the request contents are the same, the resource with the same request contents can be transmitted to the main display terminal, the main display terminal transmits the same contents to other slave display terminals in a local area network mode, specifically, a data transmission message can be generated according to a display terminal label corresponding to the resource contents, the data transmission message is transmitted in a local area network broadcast mode, when the other slave display terminals receive the transmission message, a target address in the message needs to be judged, and if the target address is consistent with the address of the main display terminal, the resource contents in the message are obtained.
Further, when the resource content corresponds to a plurality of display terminals, the resource content is sent to the corresponding display terminal according to the resource content, so that the display terminal displays the resource content, including:
when the master display terminal does not initiate a resource request, when the request contents of a plurality of display terminals are the same, ordering the network connection quality of each slave display terminal, transmitting the resource content to the slave display terminal equipment with higher network connection quality, and transmitting the slave display terminal equipment with higher network connection quality to other slave display terminals through a local area network.
In a specific implementation, when a main display terminal is not started or the main display terminal does not initiate a resource request, if a plurality of display terminal contents exist in the request contents and are the same, the network connection quality of each slave display terminal is ordered, the resource contents are transmitted to the slave display terminal equipment with higher network connection quality, the resources with the same request contents can be transmitted to the main display terminal, the slave display terminal equipment with higher network connection quality transmits the resources to other slave display terminals through a local area network, a data transmission message can be generated according to a display terminal label corresponding to the resource contents, the data transmission message is transmitted in a local area network broadcast mode, when the other slave display terminals receive the transmission message, a target address in the message needs to be judged, and if the addresses are consistent with the target address, the resource contents in the message are acquired.
If the request contents are inconsistent, a data transmission channel is established between the set top box and each real terminal to transmit the resource contents.
According to the method, the device and the system, the user permission is determined according to the voice information, the identity authentication is carried out on the user permission, the identity authentication result is obtained, when the user permission passes, the request content in the voice information is extracted, the resource content is obtained from the cloud according to the request content, when the resource content corresponds to a plurality of display terminals, the resource content is sent to the corresponding display terminals according to the resource content, so that the display terminals display the resource content.
Referring to fig. 4, fig. 4 is a flowchart of a second embodiment of a set-top box display method according to the present invention.
Based on the above first embodiment, the method for displaying a set top box in this embodiment includes:
step S101: obtaining a voice frequency spectrum of the voice information according to the voice information;
step S102: pre-emphasis processing is carried out on the voice spectrum to obtain a pre-processed spectrum;
step S103: framing and windowing the preprocessed frequency spectrum to obtain a framing frequency spectrum;

The frequency of the sound can be determined from the frequency size of the frequency spectrum. When the voice spectrum is obtained, voice information is sampled at the frequency of 4KHz, 4KHz is enhanced to 8KHz when pre-emphasis processing is carried out, the process can keep low-frequency signals unchanged, the high-frequency part of the signals is promoted, a first-order high-pass filter is adopted for processing when pre-emphasis is carried out, and the first-order high-pass filter is as follows:
wherein,the value of (2) is generally close to 1, here 0.8.
When the audio frame is processed, the audio signal is required to be subjected to framing operation, after the audio signal is subjected to framing, the audio after framing is subjected to windowing, the window size can be 192×1, and the windowing interval is 0.75, namely, the frequency image before and after the windowing is performed in the next window by one-fourth of the signal in the previous window, and fig. 5, 6 and 5 are the original audio frequency spectrum, and fig. 6 is the frequency spectrum after the windowing. The original audio signal is multiplied by a window function in the windowing process. After the windowed framing spectrum is obtained, the voice separation information is obtained through discrete time Fourier transform. The specific formula is as follows:
where x (T) is the audio signal and T is the sampling time.
The sampled signal is still a continuous time function and fourier transform can be performed:
after discrete time Fourier transform, voice separation information is obtained, the obtained voice separation information is compared with voiceprint information stored in the set top box, when the coincidence ratio of the voice separation information and the voiceprint information reaches a similar threshold value such as 80%, the current voice separation information can be judged to be consistent with the voiceprint information, so that identity authentication can be completed, the affiliated person of the current voiceprint information is determined, the authority of the user is further determined, a verification result is obtained, and the verification result comprises a judgment result of the authority of the user.
Further, in order to perform identity authentication in a complex environment, the acquiring stored voiceprint information, comparing the voiceprint information with the voice separation information, and performing identity authentication to obtain an identity authentication result includes:

counting the time length proportion of the successfully compared voice separation information and the voice information;
and outputting information of successful identity authentication when the duration proportion is greater than a preset duration proportion.
In a specific implementation, the type in the voice separation information can be detected, after noise in the voice separation information is removed, if a plurality of voice separation information exists, the duration of each voice separation information can be judged, when the voice separation duration is smaller than 1s, the current voice separation information is ignored, only voice separation information larger than 1s is processed, the rest voice separation information is compared with stored voiceprint information, when the successfully compared information is obtained, the successfully compared voice separation information is determined, the same processing operation is performed on the rest voice separation information, all successfully compared voice separation information is obtained, the duration of each successfully compared voice separation information is determined, the duration of each successfully compared with the voice information of the resource request is compared, the duration proportion of each successfully compared voice separation information is determined, when the duration proportion is larger than the preset duration proportion, the successfully authenticated information is output, and the preset duration proportion can be set according to the actual situation. The present example is preferably set to 40%.
Further, in order to determine the resource request content according to the voice information, when the user authority identity authentication passes, the method extracts the request content in the voice information, and obtains the resource content from the cloud according to the request content, including:
when the user authority identity authentication passes, the sampling frequency of the voice separation information is increased, and enhanced audio information is obtained;
performing short-time Fourier transform on the enhanced audio information, converting the enhanced audio information into a frequency domain, and performing windowing on the frequency domain to obtain audio characteristic data;

wherein,as a window function.
And window processing is performed on the frequency domain, the window function can select an exponential window function to obtain audio feature data, and when the audio is processed, noise in the audio can be filtered due to the fact that the audio signal is enhanced, so that a clean audio frequency spectrum is obtained, as shown in fig. 7, and fig. 7 is a pure audio frequency spectrum diagram.
