Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
First, an application scenario of the present disclosure will be explained. The method and the device can be applied to scenes for obtaining the audience rating of the radio broadcasting station, and in the related technology, the broadcast audio data of the radio broadcasting station played by a user through terminal equipment can be collected, and the radio broadcasting station listened to by the user is determined by comparing the broadcast audio data with the real-time audio data stored in the database. However, the inventor finds that the broadcast audio data collected in this way is greatly influenced by uncertain factors such as environmental noise, volume, distance and the like, for example, when a user chats while listening to a radio broadcasting station, the collected audio data also includes the content of the chat, and therefore, the accuracy of the listening rate of the radio broadcasting station determined according to the broadcast audio data is low. In addition, if the user listens to the radio broadcast station through the earphone, the broadcast audio data played by the radio broadcast station cannot be collected, so that the listening rate of the radio broadcast station cannot be obtained.
The multimedia data acquisition method provided by the present disclosure may be applied to a multimedia data acquisition device, which may include a bluetooth chip, an MCU (micro controller Unit), and a wireless transmission module. The MCU can receive broadcast audio data sent by the terminal equipment through the Bluetooth chip, acquire target audio data according to the broadcast audio data, and send the target audio data to the server through the wireless transmission module, so that the server can determine a target wireless broadcast station corresponding to the broadcast audio data played in the terminal equipment according to the target audio data.
Fig. 1 is a flowchart of a multimedia data collection method according to an embodiment of the present disclosure. As shown in fig. 1, the method includes:
s101, receiving broadcast audio data sent by the terminal equipment through Bluetooth.
The terminal device may be a smart phone, a tablet computer, a car radio, or other devices that can establish a bluetooth connection with the multimedia data acquisition device, which is not limited by the present disclosure.
In this step, after determining the terminal device that needs to collect the broadcast audio data, a bluetooth connection may be established with the terminal device. After the Bluetooth connection is established with the terminal equipment, the broadcasting audio data which is sent by the terminal equipment and is being played can be received through Bluetooth.
And S102, acquiring target audio data according to the broadcast audio data.
In this step, after receiving the broadcast audio data sent by the terminal device, the broadcast audio data may be encrypted by an encryption algorithm of a common technology to obtain target audio data corresponding to the broadcast audio data.
S103, sending the target audio data to a server.
In this step, after the target audio data is obtained from the broadcast audio data, the target audio data may be sent to the server. After receiving the target audio data, the server may decrypt the target audio data to obtain broadcast audio data corresponding to the target audio data, and then may compare the broadcast audio data with audio data of a preset radio station stored in the server by using a voice recognition algorithm of a common technology to determine a target radio station corresponding to the broadcast audio data played in the terminal device. For example, if the preset radio broadcast stations include a radio broadcast station a, a radio broadcast station B, and a radio broadcast station C, the broadcast audio data is compared with the audio data of the radio broadcast station a, the radio broadcast station B, and the radio broadcast station C stored in the server, and if the broadcast audio data is the same as the audio data of the radio broadcast station B, it may be determined that the target radio broadcast station corresponding to the broadcast audio data played in the terminal device is the radio broadcast station B.
The preset radio station may be a radio station that needs to collect a listening rate, the audio data of the preset radio station stored in the server may be audio data played by each preset radio station within a preset time period, and the preset time period may be determined according to collection efficiency of the broadcast audio data, and may be, for example, 5 hours or 24 hours. In the process of playing the preset radio station, the server may store the audio data played by the preset radio station in real time.
By adopting the technical scheme, the broadcast audio data sent by the terminal equipment is received through the Bluetooth, the target audio data is obtained according to the broadcast audio data, and the target audio data is sent to the server, so that the server can determine the target wireless broadcast station corresponding to the broadcast audio data played in the terminal equipment according to the target audio data. That is to say, when a user listens to the wireless broadcasting station through the terminal device, the broadcast audio data played by the terminal device can be directly acquired through bluetooth, and the broadcast audio data is not affected by factors such as environmental noise, volume, distance and the like. Therefore, after the target audio data are obtained according to the broadcast audio data and sent to the server, the server can determine the target wireless broadcast station more accurately according to the target audio data, in addition, the broadcast audio data played by the terminal equipment can be obtained through Bluetooth, the influence of a terminal playing mode is avoided, and the broadcast audio data can be collected in any playing mode.
Fig. 2 is a flowchart of another multimedia data collection method provided in an embodiment of the present disclosure. As shown in fig. 2, the method includes:
s201, receiving broadcast audio data sent by the terminal equipment through Bluetooth.
S202, adding a time stamp to the broadcast audio data to obtain target audio data.
Wherein the time stamp includes a time when the broadcast audio data is received.
It should be noted that, since the time taken for transmitting the broadcast audio data through bluetooth is very small and can be ignored, the present disclosure can regard the time when the broadcast audio data is received as the time when the terminal device plays the broadcast audio data.
In this step, after receiving the broadcast audio data sent by the terminal device, the time when the broadcast audio data is received may be used as a time stamp, and the time stamp may be added to the broadcast audio data to obtain the target audio data. Therefore, after the server receives the target audio data, the server only needs to compare the audio data according to the time stamp, so that the comparison time of the audio data can be saved, and the acquisition efficiency of the audience rating of the radio station is improved.
In addition, the timestamp can also comprise the playing time of the broadcast audio data, and after the server receives the target audio data, the server can acquire the corresponding audio data of the preset radio station according to the playing time of the target audio data, so that the audio data only needs to be compared according to the playing time, the comparison time of the audio data can be saved, and the acquisition efficiency of the audience rating of the radio station can be improved.
Further, different sampling times may be preset for different programs, and the sampling time may be 5 seconds, 10 seconds, 15 seconds, and the like. For example, for an advertisement program, it is necessary to determine whether the user is completely listening or whether the radio broadcast station is completely playing, and a longer sampling time, for example, 15 seconds, may be set; for a variety program, a shorter sampling time, for example, 5 seconds, may be set without concern for the user to listen to it completely. Since the program broadcast by each radio broadcasting station is preset, for example, a 9-point broadcast, and a 9-point 20-point broadcast music, the received broadcast audio data can be sampled according to the broadcast time of the program.
In a possible implementation manner, after receiving broadcast audio data sent by a terminal device, sampling time corresponding to a timestamp may be obtained, and the broadcast audio data is sampled according to the sampling time to obtain target audio data. Thus, when the target audio data is transmitted to the server, the data amount of transmission can be reduced, and the transmission time can be saved.
In another possible implementation manner, after receiving the broadcast audio data sent by the terminal device, the sampling time and the sampling interval may also be determined according to the hardware configuration of the server. For example, if the hardware configuration of the server is high, a longer sampling time and a shorter sampling interval may be set, for example, the sampling time may be set to 15 seconds, and the sampling interval may be set to 5 seconds; if the hardware configuration of the server is low, a shorter sampling time and a longer sampling interval may be set, for example, the sampling time may be set to 5 seconds and the sampling interval may be set to 10 seconds. In addition, the sampling time and the sampling interval may also be determined according to the number of preset radio broadcast stations in the server, for example, if the number of preset radio broadcast stations is large, which indicates that there are many radio broadcast stations to be monitored and the data volume of target audio data to be received is large, a shorter sampling time and a longer sampling interval may be set; if the number of preset radio broadcasting stations is small, which means that the number of radio broadcasting stations to be monitored is small, and the data volume of target audio data to be received is small, a longer sampling time and a shorter sampling interval can be set.
In order to reduce the data amount of the target audio data, after receiving the broadcast audio data sent by the terminal device, the broadcast audio data may be compressed according to a preset compression rate to obtain the target audio data. The preset compression rate may be determined according to data transmission capability, or may be determined according to a preset compression rate of an audio format. For example, the broadcast audio data may be compressed into the target audio data according to a preset compression rate, or the broadcast audio data may be compressed into a preset audio format, for example, an MP3 format, and the present disclosure does not limit the compression manner. Thus, when the target audio data is transmitted to the server, the data amount of transmission can be reduced, and the transmission time can be saved.
In addition, after receiving the broadcast audio data sent by the terminal device, user information can be added to the broadcast audio data, so that the server can count the listening rate of a radio station according to the user information after receiving the target audio data; after receiving the broadcast audio data sent by the terminal device, the server may further add a device identifier to the broadcast audio data, so that after receiving the target audio data, the server may count the listening rate of the radio station according to the device identifier.
It should be noted that, since a user may use an audio playing device to listen to a radio broadcasting station, for example, the audio playing device such as a bluetooth headset or a bluetooth speaker, when using the audio playing device such as a bluetooth headset or a bluetooth speaker, the terminal device needs to establish a bluetooth connection with the audio playing device, so that the terminal device can transmit the broadcast audio data to be played to the audio playing device, and play the broadcast audio data through the audio playing device. However, the existing terminal device can only establish a bluetooth connection with one bluetooth device at the same time. Therefore, the present disclosure needs to solve the problem that a user receives broadcast audio data transmitted by a terminal device through bluetooth while listening to a radio broadcast station through an audio playing device.
In one possible implementation manner, a bluetooth connection with the audio playing device may be established, and broadcast audio data received through bluetooth may be sent to the audio playing device, so that the terminal device may play the broadcast audio data through the audio playing device.
When a user needs to use the audio playing device, the terminal device is triggered to send a bluetooth connection request message. After receiving the bluetooth connection request message, a bluetooth connection with the audio playback device may be established. And then, when the terminal equipment plays the broadcast audio data, the broadcast audio data sent by the terminal equipment can be received through the Bluetooth, and the received broadcast audio data is sent to the audio playing equipment, so that the audio playing equipment can play the broadcast audio data, and the broadcast audio data played by the terminal equipment can be collected when a user uses the audio equipment to play the broadcast audio data.
And S203, sending the target audio data to a server.
In this step, after the target audio data is obtained from the broadcast audio data, the target audio data may be sent to the server. After receiving the target audio data, the server may obtain the audio data of the at least one preset radio station corresponding to the timestamp in the target audio data, for example, if the time corresponding to the timestamp is 9 o 'clock, the audio data of the at least one preset radio station at 9 o' clock may be obtained. Then, the server may obtain sampling time corresponding to the timestamp, obtain sampling audio data corresponding to the sampling time from audio data of each preset radio station, compare the target audio data with the sampling audio data, and determine that the sampling audio data is matched with the target audio data if the target audio data is the same as the sampling audio data. For example, if the sampling time is 15 seconds, the sampling audio data of the previous 15 seconds may be obtained from the audio data of each preset radio station, the target audio data and the sampling audio data are compared, the sampling audio data identical to the target audio data is used as matching audio data, and the preset radio station corresponding to the matching audio data is used as the target radio station.
In addition, if a plurality of preset radio broadcasting stations for broadcasting the broadcast audio data are determined, an application program for broadcasting the broadcast audio data in the terminal equipment can be acquired; a target radio broadcast station is determined from a plurality of preset radio broadcast stations according to the application program.
For example, if the terminal device uses the network station application to play the broadcast audio data and determines that there are two preset radio broadcast stations playing the broadcast audio data, for example, if it is determined that both the preset radio broadcast station a and the preset radio broadcast station B play the broadcast audio data and the obtained application program of the terminal device playing the broadcast audio data is the preset radio broadcast station B, it may be determined that the target radio broadcast station is the preset radio broadcast station B.
By adopting the technical scheme, when a user listens to the wireless broadcasting station through the terminal equipment, the broadcast audio data played by the terminal equipment can be directly acquired through Bluetooth, and the broadcast audio data is not influenced by factors such as environmental noise, volume, distance and the like. Therefore, after the target audio data are obtained according to the broadcast audio data and sent to the server, the server can determine the target wireless broadcast station more accurately according to the target audio data, in addition, the broadcast audio data played by the terminal equipment can be obtained through Bluetooth, the influence of a terminal playing mode is avoided, and the broadcast audio data can be collected in any playing mode. Further, after receiving the broadcast audio data sent by the terminal device, a timestamp may be added to the broadcast audio data, or the broadcast audio data may be sampled according to the sampling time corresponding to the timestamp, or the broadcast audio data may be compressed according to a preset compression rate, so as to obtain the target audio data, thereby reducing the amount of data to be transmitted and saving the transmission time.
