Referring to fig. 3, a flowchart of a method for transmitting multimedia data according to an exemplary embodiment of the present application is shown. In the embodiment of the application, the execution main body is an electronic device, and in the embodiment of the application, the electronic device is used for transmitting multimedia data based on a short-distance communication module, and the short-distance communication module is illustrated by taking bluetooth as an example. The method comprises the following steps:

step 301: the electronic device determines the number of available channels for bluetooth.

The number of available channels is used to represent the remaining resources. The number of available channels includes the number of available frequency hopping channels reflecting the number of other electronic devices in the environment in which the electronic device is located and the distance of the other electronic devices from the local electronic device. When there are many other co-band devices in the vicinity (co-band devices include 802.11b/g/n modulation devices, such as routers, mobile phone hotspots, etc., other bluetooth devices, zigbee protocol devices, such as smart home devices of various types), the available channels for frequency hopping can be reduced when the environment is noisy. When the vicinity is clear and the environment is quiet, the frequency hopping available channels increase.

Referring to fig. 4, an electronic device includes an adaptive frequency hopping (Adaptive Frequency Hopping, AFH) module and a bluetooth transmit/receive module therein; the Bluetooth transmitting/receiving module is communicated with the opposite-end electronic equipment through a physical link; the AFH module periodically determines the number of available channels for bluetooth. The scenes are classified through available channels of the multimedia data to be transmitted, the classification conditions of the scenes are judged, and the subsequent low-power transmission mode is decided to be entered or the default transmission mode is kept.

Step 302: the electronic device determines a first environmental quality parameter for which the number of available channels matches.

The first environmental quality parameter predicts the experience that the user obtains after the multimedia data is transmitted at this time. The first environmental quality parameter is inversely related to the number of available channels, and the first environmental quality parameter is used to indicate the quality of transmission resources of the environment in which the electronic device is located. And the electronic equipment carries out quantization processing on the number of the available channels to obtain a first environment quality parameter.

In some embodiments, the electronic device pre-stores a correspondence between the number of available channels and the environmental quality parameter; accordingly, the step of the electronic device determining a first environmental quality parameter for which the number of available channels matches comprises: the electronic equipment acquires a first environment quality parameter corresponding to the number of the available channels from the corresponding relation between the number of the available channels and the environment quality parameter. In the embodiment of the application, the electronic device determines the first environmental quality parameter directly based on the corresponding relation between the number of the available channels and the environmental quality parameter, so that the efficiency is improved.

With continued reference to fig. 4, the electronic device further includes an environmental information detection module, where the environmental detection module is electrically connected to the AFH module, and the environmental information detection module is in continuous operation, and after the AFH module detects the number of available channels, the number of available channels is transmitted to the environmental information detection module, and the environmental information detection module determines a first environmental quality parameter that matches the number of available channels. The environment information detection module carries out quantization processing on the number of the available channels to obtain a first environment quality parameter.

After the electronic equipment determines the first environmental quality parameter, determining whether the first environmental quality parameter is smaller than the reference environmental quality parameter; in case the first environmental quality parameter is smaller than the reference environmental quality parameter, performing step 303; executing step 304 in case the first environmental quality parameter is greater than the reference environmental quality parameter; in case the first environmental quality parameter is equal to the reference environmental quality parameter, step 305 is performed.

It should be noted that, the reference environmental quality parameter may be preset, or may be determined based on a historical environment of the electronic device; in the case where the reference environmental quality parameter is determined based on the historical environment of the electronic device, then the process of the electronic device determining the reference environmental quality parameter includes: the electronic equipment acquires a plurality of second environmental quality parameters, wherein the plurality of second environmental quality parameters are environmental quality parameters of the electronic equipment in a first historical preset time period; and determining the average value of the plurality of second environmental quality parameters to obtain the reference environmental quality parameters. The first preset time period can be set and changed according to needs, and in the embodiment of the present application, the preset time period is not specifically limited; for example, the first preset time period is 24 hours or 48 hours; in the case where the first preset time period is 48 hours, the electronic device determines an average value of environmental quality parameters of the past 48 hours as a reference environmental quality parameter.

Another point to be described is that after the electronic device obtains the first environmental quality parameter, the first environmental quality parameter and the current time are stored in an associated manner, so that the reference environmental quality parameter is updated based on the stored association relationship between the first environmental quality parameter and the current time. Referring to fig. 5, the electronic device receives a first environmental quality parameter, determines a reference environmental quality parameter through a mean value filtering algorithm, and stores the first environmental quality parameter in a ROM; it is determined whether the first environmental quality parameter is greater than a reference environmental quality parameter (average of environmental quality parameters over the past 48 hours).

In some embodiments, after determining the first environmental quality parameter, the electronic device obtains a plurality of third environmental quality parameters, where the plurality of third environmental quality parameters are environmental quality parameters of the electronic device in a second historical preset time period, determines a mean value of the first environmental quality parameter and the plurality of third environmental quality parameters, and if the mean value is smaller than the reference environmental quality parameter, performs the step of obtaining a transmission parameter corresponding to the first transmission mode in step 303, and determines the transmission parameter corresponding to the first transmission mode as a target transmission parameter; and if the average value is greater than the reference environmental quality parameter, executing the step of acquiring the transmission parameter corresponding to the second transmission mode in step 304, and determining the transmission parameter corresponding to the second transmission mode as the target transmission parameter.

The second preset time period is different from the first preset time period; for example, the first preset time period is the past 48 hours and the second preset time period is the past 24 hours; by determining the average value of the first environmental quality parameter and the plurality of third environmental quality parameters and comparing the average value with the reference environmental quality parameter, the transmission parameter is determined, a time domain average value filtering algorithm can be realized, the influence caused by environmental waves is eliminated, and the accuracy is improved.

Step 303: and under the condition that the first environmental quality parameter is smaller than the reference environmental quality parameter, the electronic equipment acquires the transmission parameter corresponding to the first transmission mode, and determines the transmission parameter corresponding to the first transmission mode as the target transmission parameter.

In this embodiment, a default transmission mode and a first transmission mode are set, where a transmission parameter corresponding to the first transmission mode is smaller than a transmission parameter corresponding to the default transmission mode, that is, the first transmission mode is a low-power transmission mode. The transmission parameters include at least one of a transmission rate, a sampling rate, and a coding rate. In the related art, only a default transmission mode is set in the electronic device, so that in order to preferentially ensure the transmission quality of the multimedia data, the sampling rate and the coding rate of the transmission rate corresponding to the default transmission mode are both kept the same, and are also larger values, and a transmission scheme for controlling the power consumption according to the environment in which the electronic device is located is lacking. Moreover, in the electronic device, in the scenes of noisy environment, dense people stream and the like, the user cannot perceive the quality of the multimedia data. At this time, high sound quality is still maintained, and modulation and coding resources of the electronic device are wasted. At this time, due to the severe environment, the work of copying the data packet, detecting whether the data is successfully sent or not, retransmitting the data packet and the like in the transmission process is increased, so that the work of the electronic equipment is increased, the power consumption and the heat generation are additionally increased, and the power consumption of the electronic equipment is high and the cruising ability is poor.

In this application, in addition to setting the default transmission mode, a first transmission mode is also set, and the first transmission mode is a low-power transmission mode. When the electronic equipment is in the scenes of noisy environment, dense people flow and the like, the electronic equipment enters a low-power transmission mode, so that the power consumption of the electronic equipment is additionally reduced on the basis of the existing protocol. In addition, in the scenes of quiet environment, sparse people flow and the like, the electronic equipment enters the default transmission mode, so that the electronic equipment can be dynamically and intelligently switched between the default transmission mode and the low-power transmission mode without operation of a user, and convenience is brought to the user. For example, with continued reference to fig. 5, if the first environmental quality parameter is greater than the reference environmental quality parameter (the average of the environmental quality parameters over the past 48 hours), then a default transmission mode is entered; if the first environmental quality parameter is less than the reference environmental quality parameter (the average of the environmental quality parameters over the past 48 hours), a low power transmission mode is entered.

It should be noted that the electronic device may set only one first transmission mode, that is, one low-power transmission mode, or may set a plurality of first transmission modes, that is, a plurality of low-power transmission modes; the transmission parameters corresponding to each first transmission mode are smaller than the transmission parameters corresponding to the default transmission mode, and the transmission parameters corresponding to each first transmission mode are different. Under the condition that a plurality of first transmission modes are set, the step of acquiring the transmission parameters corresponding to the first transmission modes by the electronic equipment comprises the following steps: the electronic equipment determines a first target transmission mode matched with the first environmental quality parameter based on the first environmental quality parameter, and obtains transmission parameters corresponding to the first target transmission mode.

In some embodiments, the electronic device sets each first transmission mode to correspond to a range of environmental quality parameters; accordingly, the step of the electronic device determining a first target transmission mode for which the first environmental quality parameter matches comprises: the electronic equipment determines a target environment quality parameter range based on the first environment quality parameters and the environment quality parameter range corresponding to each first transmission mode, wherein the target environment quality parameter range is the environment quality parameter range where the first environment quality parameters are located, and determines a first target transmission mode corresponding to the target environment quality parameter range.

In the embodiment of the application, the electronic equipment sets a plurality of low-power-consumption transmission modes, and determines the target low-power-consumption transmission mode based on the first environment quality parameter, so that the transmission parameter corresponding to the target low-power-consumption transmission mode can be accurately determined, and the accuracy is improved.

Step 304: and under the condition that the first environmental quality parameter is larger than the reference environmental quality parameter, the electronic equipment acquires the transmission parameter corresponding to the second transmission mode, and determines the transmission parameter corresponding to the second transmission mode as the target transmission parameter.

The transmission parameter corresponding to the second transmission mode is larger than the transmission parameter corresponding to the default transmission mode. In this application, in addition to the default transmission mode and the first transmission mode (low power transmission mode), a second transmission mode, that is, a high power transmission mode is set. In the scenes of quiet environment, sparse people flow and the like, the electronic equipment enters a high-power transmission mode, so that the quality of the transmitted multimedia data can be improved.

It should be noted that the electronic device may set only one second transmission mode, that is, one high-power transmission mode, or may set a plurality of second transmission modes, that is, a plurality of high-power transmission modes; the transmission parameters corresponding to each second transmission mode are larger than the transmission parameters corresponding to the default transmission mode, and the transmission parameters corresponding to each second transmission mode are different. In the case that a plurality of second transmission modes are set, the step of the electronic device obtaining the transmission parameters corresponding to the second transmission modes includes: the electronic equipment determines a second target transmission mode matched with the first environmental quality parameter based on the first environmental quality parameter, and obtains transmission parameters corresponding to the second target transmission mode.

In some embodiments, the electronic device sets each of the second transmission modes to correspond to a range of environmental quality parameters; accordingly, the step of the electronic device determining the second target transmission mode for which the first environmental quality parameter matches includes: the electronic equipment determines a target environment quality parameter range based on the first environment quality parameter and the environment quality parameter range corresponding to each second transmission mode, wherein the target environment quality parameter range is the environment quality parameter range where the first environment quality parameter is located, and the second target transmission mode corresponding to the target environment quality parameter range is determined.

In the embodiment of the application, the electronic equipment sets a plurality of high-power-consumption transmission modes, and determines the target high-power-consumption transmission mode based on the first environment quality parameter, so that the transmission parameter corresponding to the target high-power-consumption transmission mode can be accurately determined, and the accuracy is improved.

Step 305: under the condition that the first environmental quality parameter is equal to the reference environmental quality parameter, the electronic equipment acquires the transmission parameter corresponding to the default transmission mode, and determines the transmission parameter corresponding to the default transmission mode as the target transmission parameter.

With continued reference to fig. 4, the electronic device includes a mode selection module, where the mode selection module is electrically connected to the environmental information detection module, and after the environmental information detection module determines the first environmental quality parameter, the environmental information detection module transmits the first environmental quality parameter to the mode selection module, and the mode selection module performs mode selection, that is, selects whether to enter the low power transmission mode or the default transmission mode or the high power transmission mode.

Referring to fig. 6, the basic logic of the mode selection module to select the mode is: when the environment is noisy, the perception of the user to the multimedia quality is not strong, the requirement is not high, and the smooth transmission of the multimedia data is ensured at the moment, so that the quality of the multimedia data is not required to be pursued. Thus, in a noisy environment, the electronic device may reduce the transmission parameters, i.e. enter a low power transmission mode. When the environment is quiet and people are few, users expect a better and richer multimedia experience, and the electronic device needs to recover the original transmission parameters, that is, enter a default transmission mode. Of course, when the environment is very quiet and the environment is clear, users expect a better quality and richer multimedia experience, and the electronic device needs to raise the transmission parameters, that is, enter a high-power transmission mode. In fig. 6, the mode selection module is exemplified as switching between the default transmission mode and the low power transmission mode.

Step 306: the electronic device transmits the multimedia data based on the target transmission parameters.

The target transmission parameter includes at least one of a target transmission rate, a target sampling rate, and a target coding rate.

In some embodiments, the target transmission parameter includes a target transmission rate, and the step of transmitting the multimedia data by the electronic device based on the target transmission parameter includes: the electronic equipment transmits the multimedia data based on the target transmission rate; that is, the multimedia data is sent to the electronic device at the opposite terminal according to the transmission rate as the target transmission rate.

In some embodiments, the target transmission parameter comprises a target sampling rate, and the step of transmitting the multimedia data by the electronic device based on the target transmission parameter comprises: the electronic equipment samples the multimedia data based on the target sampling rate, and transmits the sampled multimedia data, namely, sends the sampled multimedia data to the opposite-end electronic equipment.

In some embodiments, the target transmission parameter includes a target coding rate, and the step of transmitting the multimedia data by the electronic device based on the target transmission parameter includes: the electronic equipment encodes the multimedia data based on the target encoding code rate, and transmits the encoded multimedia data, namely, transmits the encoded multimedia data to the opposite-end electronic equipment.

It should be noted that, in the case where the target transmission parameter includes a plurality of transmission parameters, the electronic device transmits the multimedia data based on the plurality of transmission parameters. For example, in the case where the target transmission parameter includes a target transmission rate, a target sampling rate, and a target coding rate, the step of transmitting the multimedia data by the electronic device based on the target transmission parameter includes: the electronic equipment samples the multimedia data based on the target sampling rate, codes the sampled multimedia data based on the target coding rate, and transmits the coded multimedia data based on the target transmission rate, namely transmits the coded multimedia data to the opposite-end electronic equipment.

Another point to be described is that in the low power transmission mode, by reducing the transmission parameters, that is, reducing the sampling rate of the multimedia data and reducing the coding rate of the multimedia data, the transmission is equivalent to the transmission after the compression processing of the multimedia data, and the transmission time is reduced without changing the transmission power, thereby reducing the power consumption of bluetooth. Meanwhile, due to the reduction of the transmission data quantity, the work of copying the data packet, detecting whether the data is successfully transmitted, discarding the data packet and the like in the transmission process is reduced, the resource consumption in the transmission process can be reduced, the power consumption of the electronic equipment is reduced, and the heating of the electronic equipment is reduced. In addition, the power consumption is reduced by means of reducing the coding code rate, the sampling rate and the like, the power consumption can be saved on the premise that the user cannot perceive the environment when the environment is noisy, and the environment is recovered and is automatically recovered after being quiet, so that the functions of intelligently reducing the power consumption, heating and prolonging the endurance are realized.

In the embodiment of the application, the electronic device adjusts the target sampling rate, the target coding rate and the target transmission rate, so that the electronic device is dynamically switched in a default transmission mode and a low-power transmission mode (or the electronic device is dynamically switched in the default transmission mode, the high-power transmission mode and the low-power transmission mode). By using the transmission mode and the switching algorithm in the scheme, the working consumption of a Bluetooth coder-decoder (codec) and a Bluetooth transmitting module is reduced, the resources consumed by a physical link are reduced, and the power consumption is reduced under the conditions that the user experience of the current activated application is ensured and the requirements of the electronic equipment on the data delay and the reliability are also ensured.

In the embodiment of the application, since the first environmental quality parameter is used for representing the quality of the transmission resource of the environment where the electronic device is located, the target transmission parameter matched with the first environmental quality parameter can be adapted to the environment where the first electronic device is located, so that the accuracy of the determined target transmission parameter is improved, and the multimedia data is transmitted based on the target transmission parameter, so that the transmission performance can be improved.

Referring to fig. 7, a flowchart of a method for transmitting multimedia data according to an exemplary embodiment of the present application is shown. In the embodiment of the present application, the execution body is an electronic device, and in the embodiment of the present application, an example is described in which the electronic device and the second electronic device communicate through a cellular mobile network. The method comprises the following steps:

Step 701: the electronic device determines at least one of a remaining frequency band and a remaining bandwidth of the cellular mobile network, and determines the at least one of the remaining frequency band and the remaining bandwidth as a remaining resource.

The remaining frequency band and the remaining bandwidth are used to represent the remaining resources. And the residual frequency band and the residual bandwidth can reflect whether the environment where the user is located is outdoor or indoor, and the people flow at the position where the user is located is dense or sparse, so that the accurate and reasonable power consumption allocation requirement is achieved through the judgment of the scene.

Step 702: the electronic device determines a first environmental quality parameter for which the remaining resources match.

The first environmental quality parameter is inversely related to the remaining resources; and the electronic equipment carries out quantization processing on the residual resources to obtain a first environment quality parameter.

In some embodiments, the electronic device pre-stores a correspondence between the remaining resources and the environmental quality parameter; accordingly, the step of the electronic device determining the first environmental quality parameter that the remaining resources match includes: the electronic equipment acquires a first environment quality parameter corresponding to the residual resource from the corresponding relation between the residual resource and the environment quality parameter. In the embodiment of the application, the electronic equipment directly determines the first environment quality parameter based on the corresponding relation between the residual resources and the environment quality parameter, so that the efficiency is improved.

Step 703: and under the condition that the first environmental quality parameter is smaller than the reference environmental quality parameter, the electronic equipment acquires the transmission parameter corresponding to the first transmission mode, and determines the transmission parameter corresponding to the first transmission mode as the target transmission parameter.

Step 704: and under the condition that the first environmental quality parameter is larger than the reference environmental quality parameter, the electronic equipment acquires the transmission parameter corresponding to the second transmission mode, and determines the transmission parameter corresponding to the second transmission mode as the target transmission parameter.

The transmission parameter corresponding to the second transmission mode is larger than the transmission parameter corresponding to the default transmission mode.

Step 705: under the condition that the first environmental quality parameter is equal to the reference environmental quality parameter, the electronic equipment acquires the transmission parameter corresponding to the default transmission mode, and determines the transmission parameter corresponding to the default transmission mode as the target transmission parameter.

Step 706: the electronic device transmits the multimedia data based on the target transmission parameters.

It should be noted that the implementation process of steps 703-706 is the same as the implementation process of steps 303-306, and will not be described here again.

Under the condition that the first environmental quality parameter is not smaller than the reference environmental quality parameter, the electronic equipment acquires the transmission parameter corresponding to the second transmission mode, and the transmission parameter corresponding to the second transmission mode is larger than the transmission parameter corresponding to the default transmission mode; and determining the transmission parameter corresponding to the second transmission mode as a target transmission parameter.
