Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before introducing the method, the apparatus, the storage medium, and the electronic device for monitoring broadcast content provided by the present disclosure, an application scenario related to various embodiments of the present disclosure is first introduced. The embodiments of the present disclosure may be applied to a scenario in which broadcast content is monitored, and the application scenario may include a terminal and a server. The terminal and the server can communicate with each other through any one of a Wireless Local Area Network (WLAN), a 4G (4 th Generation mobile communication technology, chinese: fourth Generation mobile communication technology) and a 5G (5 th Generation mobile communication technology, chinese: fifth Generation mobile communication technology) protocol, so as to realize data transmission. The terminal can be a mobile terminal such as a smart phone, a tablet computer and a smart watch, and can also be a fixed terminal such as a desktop computer, and the server can include but is not limited to: an entity server, a server cluster or a cloud server, etc.
Fig. 1 is a flow chart illustrating a method of monitoring broadcast content according to an exemplary embodiment. As shown in fig. 1, the method is applied to a terminal, the terminal includes a radio unit, the radio unit includes a radio chip and a broadcast antenna, and the method includes the following steps:
step 101, receiving monitoring information sent by a server, wherein the monitoring information includes a target frequency of a broadcast signal to be monitored.
For example, when a user needs to monitor broadcasts of one or more broadcast channels, the server may generate monitoring information according to a target frequency of a broadcast signal to be monitored, and send the monitoring information to the terminal, so as to instruct the terminal to acquire a corresponding broadcast signal (i.e., a target broadcast signal described later) according to the target frequency. For example, a server may be provided with corresponding monitoring management software in advance, and a user may generate monitoring information by inputting a target frequency at a designated position on a page of the monitoring management software. After receiving the monitoring information, the terminal may monitor the broadcast signal to be monitored according to the monitoring information.
Step 102, acquiring a target broadcast signal corresponding to a target frequency acquired by a radio unit and target time information corresponding to the target broadcast signal.
In an example, a radio unit is arranged in the terminal, the radio unit includes a radio chip and a broadcast antenna, and the radio chip is connected with the broadcast antenna. The broadcast antenna may be, for example, a non-directional antenna, and the radio chip is configured to control the broadcast antenna to receive a broadcast signal with a specific frequency. After the terminal receives the monitoring information, the radio chip of the radio unit can be configured according to the target frequency included in the monitoring information, so that the radio chip can acquire a target broadcast signal corresponding to the target frequency through the broadcast antenna. Monitoring the broadcast usually requires 24 hours of uninterrupted monitoring, and in order to facilitate analysis processing of the target broadcast signal, the target broadcast signal may be continuously collected by the radio chip according to a preset period (the preset period may be, for example, 1 min), that is, the target broadcast signal is a broadcast signal sent by a broadcast corresponding to the target frequency collected by the radio chip in each preset period. When the radio chip collects the target broadcast signal, target time information corresponding to the target broadcast signal can be collected, and the target time information can include: a start time and an end time. Furthermore, in order to improve the signal quality of the acquired target broadcast signal, the power supply of the radio chip may be subjected to crosstalk suppression to reduce the influence of crosstalk on the target broadcast signal, so as to improve the signal quality of the target broadcast signal.
It should be noted that, in the case that the target frequency is multiple (that is, in the case that the user needs to monitor the broadcast of multiple broadcast channels at the same time), the number of the radio receiving chips may be multiple, and the number of the broadcast antennas may be one or multiple. Each radio chip corresponds to a target broadcast signal, namely each radio chip corresponds to a broadcast channel. The correspondence between the radio receiving chip and the target broadcast signal may be controlled by using a bus, for example, an I2C (Inter-Integrated Circuit) bus may be used to configure the correspondence between the radio receiving chip and the target broadcast signal. A plurality of radio chips may be integrated on the radio board, for example, 12 radio chips may be integrated on the radio board, that is, at most, broadcast of 12 channels may be monitored simultaneously. When the number of the broadcast antennas is one, the plurality of radio chips may use a broadcast antenna sharing manner to obtain the target broadcast signal corresponding to each radio chip. By adopting the mode of sharing the broadcast antenna, the cost can be saved, and the occupied space of the radio unit is reduced. When the number of the broadcast antennas is multiple, each radio chip corresponds to one broadcast antenna, and each radio chip acquires a target broadcast signal corresponding to the radio chip through the broadcast antenna corresponding to the radio chip.
Step 103, performing signal processing on the target broadcast signal to obtain an audio signal.
In this step, the terminal may first perform filtering processing on the target broadcast signal through the radio receiving chip, and perform amplification processing on the filtered target broadcast signal to obtain the first broadcast signal. For example, the filtering process and the amplifying process of the target broadcasting signal can be realized by an LNA (low noise amplifier) provided in the radio chip. The first broadcast signal is demodulated by the radio chip (for example, the first broadcast signal may be demodulated by a demodulator provided in the radio chip), and the demodulated first broadcast signal is subjected to analog-to-digital conversion (abbreviated as a/D) to obtain a digitized audio signal. The analog-to-digital conversion of the demodulated first broadcast signal can be implemented by an a/D acquisition module (e.g., a sound card).
And 104, extracting the audio features of the audio signals, and sending the audio features and the target time information to the server, so that the server determines the target sample features according to the audio features, and determines the monitoring result according to the target sample features and the target time information.
Specifically, after the terminal acquires the audio signal, the terminal may perform feature extraction on the audio signal to extract audio features of the audio signal, and send the audio features and the target time information to the server through an FTP (File Transfer Protocol). The way of extracting the audio features may be, for example: and (2) performing feature extraction on the audio signal by adopting an MFCC (Mel Frequency Cepstrum Coefficient, chinese) feature extraction mode to obtain audio features. After receiving the audio features and the target time information, the server may match the audio features with a plurality of sample features stored in a sample database to determine whether there is a target sample feature matching the audio features. And if the target sample characteristics exist, determining a monitoring result according to whether the time information corresponding to the target sample characteristics is matched with the target time information. And if the time information corresponding to the target sample characteristics is matched with the target time information, determining that the monitoring result is normal. And if the time information corresponding to the target sample characteristics is not matched with the target time information, determining that the monitoring result is abnormal. And if the target sample characteristics do not exist, determining that the monitoring result is abnormal.
Furthermore, the terminal can generate a recording file with a specified format according to the audio signal, and the recording file is periodically uploaded to the server, so that a user can perform exception analysis according to the recording file when the monitoring result is abnormal. The specified Format may be, for example, formats such as AIFF (Audio exchange File Format), MP3 (MPEG Audio layer-3), WMA (Windows Media Audio).
In summary, in the present disclosure, a terminal first receives monitoring information sent by a server, where the monitoring information includes a target frequency of a broadcast signal to be monitored, then obtains a target broadcast signal corresponding to the target frequency and target time information corresponding to the target broadcast signal, which are collected by a radio unit of the terminal, and performs signal processing on the target broadcast signal to obtain an audio signal, and finally extracts an audio feature of the audio signal, and sends the audio feature and the target time information to the server, so that the server determines a target sample feature according to the audio feature, and determines a monitoring result according to the target sample feature and the target time information. According to the method and the device, the audio characteristics contained in the target broadcast signal are extracted through the terminal, the audio characteristics and the target time information are sent to the server, the server monitors the broadcast content according to the audio characteristics and the target time information, manual participation is not needed, the monitoring efficiency of the broadcast content is improved, and the monitoring cost is reduced.
Fig. 2 is a flow chart illustrating another method of monitoring broadcast content according to an example embodiment. As shown in fig. 2, the monitoring information further includes a radio parameter and a collecting instruction, where the collecting instruction is used to instruct the terminal to obtain a signal quality and a signal-to-noise ratio parameter of the target broadcast signal, before step 102, the method further includes the following steps:
and 105, configuring the radio receiving unit according to the radio receiving parameters so that the radio receiving unit can acquire the target broadcast signal according to the radio receiving parameters.
In one scenario, a user can generate radio reception parameters through the server according to actual requirements and send the radio reception parameters to the terminal, so that the terminal is instructed to acquire a target broadcast signal according to the radio reception parameters. The sound reception parameters may include, for example: at least one of a filter coefficient, an amplification coefficient, and a sound reception volume. After receiving the radio reception parameters, the terminal can configure the radio reception unit according to the radio reception parameters, so that the radio reception unit can acquire a target broadcast signal according to the radio reception parameters. For example, when the sound reception parameter only includes the sound reception volume, the terminal may adjust the audio amplifier of the sound reception chip according to the sound reception volume, so that the sound reception chip collects the target broadcast signal according to the sound reception volume.
Further, the monitoring requirement of the user may change, for example, when the user needs to monitor the broadcast of other broadcast channels, the monitoring information may be updated, and the monitoring information including the new target frequency is sent to the terminal, so that the terminal configures the radio chip according to the new target frequency, so that the radio chip may collect a target broadcast signal corresponding to the new target frequency through the broadcast antenna.
After step 102, the method further comprises the steps of:
and 106, responding to the acquisition instruction, acquiring the signal quality and signal-to-noise ratio parameters, and sending the signal quality and signal-to-noise ratio parameters to the server.
In another scenario, in order to further improve the monitoring effect, the signal quality and the signal-to-noise ratio of the target broadcast signal may also be monitored. For example, a user may send monitoring information including a collection instruction through the server, and after receiving the collection instruction, the terminal may start collection software preset in the terminal according to the collection instruction, collect the signal quality and signal-to-noise ratio parameters of the target broadcast signal through the collection software, and send the signal quality and signal-to-noise ratio parameters of the target broadcast signal to the server.
In summary, in the disclosure, a terminal first receives monitoring information sent by a server, where the monitoring information includes a target frequency of a broadcast signal to be monitored, then obtains a target broadcast signal corresponding to the target frequency and target time information corresponding to the target broadcast signal, which are collected by a radio unit of the terminal, and performs signal processing on the target broadcast signal to obtain an audio signal, and finally extracts an audio feature of the audio signal, and sends the audio feature and the target time information to the server, so that the server determines a target sample feature according to the audio feature, and determines a monitoring result according to the target sample feature and the target time information. According to the method and the device, the audio characteristics contained in the target broadcast signal are extracted through the terminal, the audio characteristics and the target time information are sent to the server, the server monitors the broadcast content according to the audio characteristics and the target time information, manual participation is not needed, the monitoring efficiency of the broadcast content is improved, and the monitoring cost is reduced.
Fig. 3 is a flow chart illustrating a method of monitoring broadcast content according to an example embodiment. As shown in fig. 3, applied to a server, the method includes the following steps:
step 201, sending monitoring information to the terminal, where the monitoring information includes a target frequency of a broadcast signal to be monitored, so that the terminal obtains a target broadcast signal corresponding to the target frequency and target time information corresponding to the target broadcast signal according to the monitoring information.
For example, when a user needs to monitor the broadcast of one or more broadcast channels, the server may generate monitoring information according to a target frequency of a broadcast signal to be monitored, and send the monitoring information to the terminal, so as to instruct the terminal to acquire a corresponding broadcast signal according to the target frequency. After receiving the monitoring information, the terminal may monitor the broadcast signal to be monitored according to the monitoring information.
Step 202, receiving audio characteristics and target time information sent by a terminal, wherein the audio characteristics are characteristics extracted from audio signals by the terminal by performing signal processing on target broadcast signals to acquire the audio signals.
Step 203, determining whether a target sample characteristic matched with the audio characteristic exists in a plurality of preset sample characteristics according to the audio characteristic, and determining a monitoring result according to the matching result and the target time information.
In an example, taking the example that whether a broadcast corresponding to a monitoring target frequency broadcasts a specified advertisement or not as an example for explanation, a user may perform feature extraction on original audio of one or more advertisements to be monitored in advance to extract a sample feature corresponding to the original audio of each advertisement, set time information (the time information may include a start time and an end time) corresponding to each sample feature according to a time required for playing each advertisement, and store each extracted sample feature and the time information corresponding to the sample feature in a sample database of a server. After receiving the monitoring information, the terminal may configure a radio chip of the radio unit according to the target frequency, so that the radio chip may acquire a target broadcast signal corresponding to the target frequency and target time information corresponding to the target broadcast signal through the broadcast antenna. And then the terminal can sequentially carry out filtering processing, amplification processing, demodulation and analog-to-digital conversion on the target broadcast signal to obtain a digitized audio signal, extract the audio characteristics of the audio signal and send the audio characteristics and the target time information to the server.
After receiving the audio features and the target time information, the server may match the audio features with a plurality of sample features stored in the sample database to determine whether there are target sample features matching the audio features. And if the target sample characteristics exist, determining a monitoring result according to whether the time information corresponding to the target sample characteristics is matched with the target time information. And if the time information corresponding to the target sample characteristics is matched with the target time information, determining that the monitoring result is normal, namely, the specified advertisement is played normally. And if the time information corresponding to the target sample characteristics is not matched with the target time information, determining that the monitoring result is abnormal, namely that the specified advertisement is not played normally. And if the target sample characteristics do not exist, determining that the monitoring result is abnormal, namely that the specified advertisement is not played normally.
In summary, in the present disclosure, a server first sends monitoring information to a terminal, where the monitoring information includes a target frequency of a broadcast signal to be monitored, so that the terminal obtains a target broadcast signal corresponding to the target frequency and target time information corresponding to the target broadcast signal according to the monitoring information, then receives audio features and the target time information sent by the terminal, where the audio features are characteristics extracted from the audio signal by the terminal by processing the target broadcast signal by the terminal, and finally determines whether a target sample feature matching the audio feature exists from a plurality of preset sample features according to the audio features, and determines a monitoring result according to the matching result and the target time information. According to the method and the device, the server receives the audio characteristics and the target time information sent by the terminal, and determines the monitoring result of the broadcast content according to the audio characteristics and the target time information, so that manual participation is not needed, the monitoring efficiency of the broadcast content is improved, and the monitoring cost is reduced.
Fig. 4 is a flowchart of one step 203 shown in the embodiment of fig. 3. As shown in fig. 4, step 203 comprises the following steps:
step 2031, matching the audio features with each sample feature to obtain a matching degree between the audio features and each sample feature.
For example, after receiving the audio features and the target time information, the server may match the audio features with each sample feature to obtain a matching degree of the audio features with each sample feature. The matching degree can be understood as the similarity degree between the audio features and the sample features, and the higher the matching degree, the higher the similarity degree between the audio features and the sample features is, that is, the more similar the audio signal is to the original audio. The lower the matching degree, the lower the similarity degree of the audio features and the sample features, i.e. the less similar the audio signal is to the original audio.
Step 2032, if there is a sample feature with a matching degree greater than or equal to a preset threshold, determining that there is a target sample feature, and taking the sample feature with the matching degree greater than or equal to the preset threshold as the target sample feature.
Step 2033, determining first time information corresponding to the target sample characteristic according to the target sample characteristic and a preset corresponding relationship, where the preset corresponding relationship is a corresponding relationship between the sample characteristic and the first time information.
Step 2034, determining whether the monitoring result is normal or not according to the target time information and the first time information.
Step 2035, if there is no sample feature with a matching degree greater than or equal to the preset threshold, determining that there is no target sample feature, and determining that the monitoring result is abnormal.
For example, a preset threshold may be set in the server, where the preset threshold is a feature set according to a lot of experiments for determining whether the audio feature is the original audio (i.e., for determining whether the audio signal is the original audio). If the matching degree is greater than or equal to the preset threshold, determining that the audio feature corresponding to the matching degree is the feature of the original audio, that is, the audio signal is a certain original audio. If the matching degree is greater than or equal to the preset threshold, determining that the audio features corresponding to the matching degree are not the features of the original audio, namely the audio signal is not a certain original audio.
If the sample characteristics with the matching degree larger than or equal to the preset threshold exist, determining that the target sample characteristics exist (namely the audio signal is the original audio corresponding to the target sample characteristics), and taking the sample characteristics with the matching degree larger than or equal to the preset threshold as the target sample characteristics. And then the server determines first time information corresponding to the target sample characteristics according to the target sample characteristics and the preset corresponding relation. The preset correspondence may be a correspondence between each sample feature stored in the sample database and time information corresponding to the sample feature. Then, whether the target time information and the first time information are matched or not can be determined according to the target time information and the first time information. For example, it may be determined whether a first difference between the start time included in the target time information and the start time included in the first time information is within a preset range, and whether a second difference between the end time included in the target time information and the end time included in the first time information is within the preset range, and if the first difference and the second difference are both within the preset range, it is determined that the target time information and the first time information are matched, and it is determined that the monitoring result is normal, that is, the original audio corresponding to the target sample feature is normally played. And if the first difference value and/or the second difference value are not in the preset range, determining that the target time information is not matched with the first time information, and determining that the monitoring result is abnormal, namely the original audio corresponding to the characteristics of the target sample is not normally played. And if the sample characteristics with the matching degree larger than or equal to the preset threshold value do not exist, determining that the target sample characteristics do not exist, and determining that the monitoring result is abnormal.

As shown in fig. 5, the monitoring information further includes a radio parameter and a collecting instruction, where the collecting instruction is used to instruct the terminal to obtain a signal quality and a signal-to-noise ratio parameter of the target broadcast signal, and step 201 may be implemented by:
and sending the radio reception parameters and the acquisition instruction to the terminal so that the terminal configures the radio reception unit according to the radio reception parameters, responds to the acquisition instruction, and sends the acquired signal quality and signal to noise ratio parameters to the server.
In one scenario, a user can generate radio parameters through a server according to actual requirements and send the radio parameters to a terminal, so that the terminal is instructed to acquire a target broadcast signal according to the radio parameters. The sound reception parameters may include, for example: at least one of a filter coefficient, an amplification coefficient, and a sound reception volume. After receiving the radio reception parameters, the terminal can configure the radio reception unit according to the radio reception parameters, so that the radio reception unit acquires the target broadcast signal according to the radio reception parameters.
The method also includes the steps of:
and step 204, receiving the signal quality and signal-to-noise ratio parameters sent by the terminal.
In another scenario, in order to further improve the monitoring effect, the signal quality and the signal-to-noise ratio of the target broadcast signal may also be monitored. For example, a user may send monitoring information including an acquisition instruction through the server, so that the terminal acquires the signal quality and signal-to-noise ratio parameters of the target broadcast signal according to the acquisition instruction, and sends the signal quality and signal-to-noise ratio parameters of the target broadcast signal to the server. After receiving the signal quality and signal-to-noise ratio parameters of the target broadcast signal, the server may store the signal quality and signal-to-noise ratio parameters of the target broadcast signal in a database, so that a user may view the signal quality and signal-to-noise ratio parameters of the target broadcast signal at any time when analyzing the monitoring result.

According to the method and the device, the server receives the audio characteristics and the target time information sent by the terminal, and determines the monitoring result of the broadcast content according to the audio characteristics and the target time information, so that manual participation is not needed, the monitoring efficiency of the broadcast content is improved, and the monitoring cost is reduced.
