Referring to fig. 1b, fig. 1b is a schematic flow chart of a multimedia data transmission method provided in the present application. The multimedia data transmission method is applied to sending equipment, and the specific flow can be as follows:
101. and acquiring a data transmission request.
The data transmission request indicates a target multimedia and a receiving device for receiving the target multimedia, where the target multimedia may be a video or an audio, and the receiving device may be a smart television, a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, or the like, and this application is not particularly limited thereto.
The bluetooth device can simultaneously inquire the nearby bluetooth devices and be discovered by the nearby bluetooth devices in a time division multiplexing mode, that is, the conventional bluetooth device can simultaneously serve as an inquiry device (Inquiring device) and a Discoverable device (Discoverable device). The inquiring device (i.e., the sending device) obtains the bluetooth address of the discoverable device by inquiring.
For example, in response to a device selection operation of a user for a discoverable device, the selected discoverable device is determined as a receiving device, so that a sending device obtains a data transmission request, specifically, the user can click a data transmission control displayed in the sending device, so that the sending device obtains the data transmission request, and the style of the data transmission control can be set according to actual conditions
102. A bluetooth connection is established with the receiving device.
Bluetooth is a radio technology that supports short-range communication (typically within 10 m) of devices, enabling wireless information exchange between many devices, including mobile phones, PDAs, wireless headsets, laptops, related peripherals, etc. With the bluetooth technology, it is possible to effectively simplify the communication between mobile communication terminal devices and also to successfully simplify the communication between the devices and the internet, so that data transmission becomes more rapid and efficient, widening the way for wireless communication.
Bluetooth, as a small-range wireless connection technology, can implement convenient, fast, flexible, secure, low-cost, low-power-consumption data communication and voice communication between devices, and thus it is one of the mainstream technologies for implementing wireless personal area network communication. Connection to other networks may lead to a wider range of applications. The wireless communication system is a sophisticated open wireless communication system, which enables various digital devices to communicate wirelessly, is one of wireless network transmission technologies, and originally used to replace infrared communication.
Bluetooth is an open global specification for wireless data and voice communication that establishes an ad hoc connection for fixed and mobile device communication environments based on low-cost short-range wireless connections. The essence of the method is to establish a universal Radio Air Interface (Radio Air Interface) for the communication environment between fixed devices or mobile devices, and further combine the communication technology with the computer technology, so that various 3C devices can realize mutual communication or operation in a short distance without mutual connection of wires or cables. Briefly, bluetooth technology is a technology for transmitting data to each other between various 3C devices using low power radio.
The bluetooth device may connect with a nearby bluetooth device and be connected with a nearby bluetooth device simultaneously in a time division multiplexing manner, that is, the bluetooth device may simultaneously serve as a Connecting device (Connecting device) and a Connectable device (Connectable device). The Connection device sending a Connection Request (Connection Request) signaling to the connectable device; the connectable device may send Connection reply (Connection Response) signaling to the connecting device. After the connection is successful, the bluetooth device initiating the connection (i.e., the transmitting device) becomes a Master (Master) in the network, and the connected bluetooth device becomes a Slave (Slave) in the network.
When detecting the bluetooth connection operation triggered by the user for the receiving device, then establishing the bluetooth connection with the receiving device, wherein the bluetooth connection operation can be triggered by clicking the bluetooth connection control, and the bluetooth connection operation can also be triggered by an interconnection system between devices, which is specific according to actual conditions and is not repeated herein.
103. And responding to the multimedia data sending operation triggered by the target multimedia, and monitoring the data to be transmitted corresponding to the target multimedia currently cached in the Bluetooth transmission queue.
It can be understood that the multimedia data is data related to the user service, such as data actually transmitted by a File Transfer Protocol ("FTP"), and the data volume of the multimedia data is usually large and usually cannot be transmitted to the corresponding receiving device in time, so that, in the present application, by detecting the to-be-transmitted data corresponding to the target multimedia currently cached in the bluetooth transmission queue, it is convenient to subsequently determine the corresponding multimedia transmission policy according to the to-be-transmitted data cached in the bluetooth transmission queue.
104. And determining a multimedia transmission strategy according to the data proportion of the data to be transmitted in the multimedia transmission queue.
The method includes determining a multimedia transmission policy corresponding to a data occupancy ratio according to the data occupancy ratio of data to be transmitted in a multimedia transmission queue, for example, the multimedia transmission policy corresponding to the data occupancy ratio of 30% is a policy a, the multimedia transmission policy corresponding to the data occupancy ratio of 30% is a policy B, and the multimedia transmission policy corresponding to the data occupancy ratio of 70% is a policy C, where in some embodiments, the policy a, the policy B, and the policy C are different in that: the transmission power of the bluetooth in the sending device is different, that is, the higher the data occupation ratio is, the higher the transmission power of the bluetooth in the sending device is, so as to improve the transmission efficiency of the multimedia data, that is, the step "determining the multimedia transmission policy according to the data occupation ratio of the data to be transmitted in the multimedia transmission queue" may specifically include:
(11) calculating the data proportion of the data to be transmitted in the multimedia transmission queue;
(12) and determining a multimedia transmission strategy according to the range interval corresponding to the data occupation ratio.
The multimedia transmission strategies corresponding to each range interval are different, and the corresponding relation between the range intervals and the multimedia transmission strategies can be constructed in advance, for example, when the data percentage of the range interval corresponding to the range interval is 30-80%, the transmission power of the Bluetooth in the sending equipment can be improved; when the range interval corresponding to the data occupation ratio is 80-100%, the transmission interval of the data to be transmitted can be reduced; if the range interval corresponding to the data percentage is 100%, the data to be transmitted may be backed up, and the backup data may be cut, that is, optionally, in some embodiments, the step "determining the multimedia transmission policy according to the range interval corresponding to the data percentage" may specifically include:
(21) acquiring a range interval corresponding to the data proportion;
(22) when the range interval corresponding to the data occupation ratio is a first range interval, improving the transmitting power of the Bluetooth in the transmitting equipment;
(23) when the range interval corresponding to the data occupation ratio is a second range interval, improving the transmission interval of the data to be transmitted;
(24) and when the range interval corresponding to the data proportion is a third range interval, backing up the data to be transmitted and cutting the backup data.
Conventional bluetooth has 3 power levels: class1, Class2, and Class3 support transmission distances of 100m, 10m, and 1m, respectively, while bluetooth low energy is in a powerless Class, and the transmission power is generally-21-5 dBm, in this application, because the data amount of the transmitted multimedia data is large, a conventional bluetooth is used, wherein when the data percentage corresponds to a first range, the transmission power of the bluetooth in the transmitting device is increased, for example, the transmission power of the bluetooth is increased from Class1 to Class2, or the transmission power of the bluetooth is increased from Class1 to Class3, which is specifically selected according to the actual situation, and is not described herein again, that is, optionally, in some embodiments, the step "increasing the transmission power of the bluetooth in the transmitting device" may specifically include:
(31) determining a power mode currently corresponding to Bluetooth in receiving equipment;
(32) and switching the power mode to a target power mode corresponding to the target transmitting power so as to improve the transmitting power of the Bluetooth.
The bluetooth can realize two modes of high power and common power, so that an additional Power Amplifier (PA) can be added on a bluetooth radio frequency channel to realize the high power design of the bluetooth.
When the range interval corresponding to the data percentage is the second range interval, the transmission interval of the data to be transmitted is decreased, for example, the transmission interval is increased from 20 milliseconds to 30 milliseconds, but other values are also possible.
When the range section corresponding to the data proportion is the third range section, the data to be transmitted is backed up, and the backup data is cut, for example, specifically, the data of the odd frame in the backup data may be retained, and the data of the even frame in the backup data may be deleted, or the first 30% of the data in the backup data may be retained, which is specifically set according to the actual situation, and is not described herein again.
105. And transmitting the target multimedia to the receiving equipment based on the multimedia transmission strategy.
For different multimedia transmission strategies, the multimedia transmission modes are different, specifically as follows:
the target multimedia is transmitted to the receiving device based on the increase of the transmission power of the bluetooth in the sending device, for example, specifically, after the transmission power of the bluetooth is increased from Class1 to Class2, the target multimedia is transmitted to the receiving device based on the transmission power of Class2, thereby avoiding the interference of wifi or other wireless signals and further improving the transmission efficiency of the multimedia data.
It should be noted that before the target multimedia is transmitted to the receiving device based on bluetooth with increased transmission power. The data occupation ratio of the data to be transmitted in the multimedia transmission queue may also be detected, and when the range interval corresponding to the data occupation ratio of the data to be transmitted in the multimedia transmission queue for which the power is increased is the first range interval, the transmission power of the bluetooth is continuously increased, that is, optionally, in some embodiments, before the step "transmitting the target multimedia to the receiving device based on the bluetooth for increasing the transmission power", specifically, the method may further include:
(41) after the transmitting power is increased, detecting the data proportion of the data to be transmitted in a multimedia transmission queue;
(42) and when the range interval corresponding to the detected data occupation ratio is the first range interval, increasing the transmission power of the Bluetooth in the sending equipment and the transmission power of the Bluetooth in the receiving equipment to the maximum value.
For example, after the transmission power of the bluetooth is increased from Class1 to Class2, when the range interval corresponding to the data percentage of the data to be transmitted in the multimedia transmission queue is still the first range interval, the transmission power of the bluetooth is increased from Class2 to Class3, and the multimedia data transmission is performed based on the bluetooth whose transmission power is increased to Class 3.
In addition, for the manner based on increasing the transmission interval of the data to be transmitted, the target multimedia can be transmitted to the receiving device based on the increased transmission interval.
In a manner of cutting the backup data, the target multimedia may be transmitted to the receiving device based on the cut backup data, where data of odd frames in the cut backup data may be retained, and data of even frames in the cut backup data is deleted to obtain the target data, and finally the target multimedia is transmitted to the receiving device based on the target data, that is, optionally, in some embodiments, the step "transmitting the target multimedia to the receiving device based on the cut backup data" may specifically include:
(51) reserving the data of the Nth frame in the cut backup data, and deleting the data of the (N + 1) th frame in the cut backup data to obtain target data, wherein N is a positive integer;
(52) and transmitting the target multimedia to the receiving device based on the target data.
In this way, the trimmed backup data is further trimmed by half, so as to reduce the data occupation ratio in the multimedia transmission queue, thereby increasing the transmission speed, and in addition, when the target data is transmitted, the data occupation ratio of the target data in the multimedia transmission queue can be detected, and when the data occupation ratio of the target data in the multimedia transmission queue is smaller than a preset value, the target multimedia is transmitted to the receiving device, wherein the preset value can be 100% or 90%, and can be specifically adjusted according to the actual transmission condition. When the data proportion of the target data in the multimedia transmission queue is greater than the preset value, continuing to perform the operation of halving the target data until the data proportion of the target data in the multimedia transmission queue after being clipped is less than the preset value, that is, optionally, in some embodiments, the method may further include:
(61) when the data proportion of the target data in the multimedia transmission queue is detected to be larger than or equal to a preset value, retaining the data of the Nth frame in the target data, and deleting the data of the (N + 1) th frame of the target data;
(62) and transmitting the target multimedia to the receiving equipment based on the data of the Nth frame in the target data.
According to the method and the device, the corresponding multimedia transmission strategy is determined according to the data proportion of the data to be transmitted in the multimedia transmission queue, different multimedia transmission strategies can be flexibly selected in different application scenes, interference caused by wifi or other wireless signals is avoided, and the transmission efficiency of the multimedia data is improved.
To further understand the multimedia data transmission method of the present application, the following description takes video as an example to further describe in detail, please refer to fig. 1c, when the TV end and the bluetooth device end (speaker/earphone) are bound and connected, a bluetooth link is established. The TV end application plays video/music and the TV audio service starts to transmit audio streams to the Bluetooth device at the opposite end. And transmitting the audio to the Bluetooth headset of the opposite end, wherein the audio is coded correspondingly according to the coding format negotiated by the two parties through a Bluetooth protocol stack. And finally, sending the audio data to the opposite-end equipment through the HCI. And the opposite terminal equipment receives the audio data, and then performs audio decoding and playing. According to the scheme, when the audio coding is carried out on the Bluetooth protocol stack, the audio transmission can be dynamically optimized and adjusted by starting the card break early warning service. When the TV end application plays video/music and starts audio stream transmission, an audio broadcast event is sent. When the system receives the broadcast event, it will start the bluetooth katon early warning service. The service runs in real time in the background and it collects data information for the tx _ audio _ queue audio send queue of the bluetooth protocol stack. The data information includes a maximum space of the queue, a currently used space of the queue, a number of data frames that the queue has discarded, and a corresponding timestamp. From this data, the percentage of pending audio data (queue used space/queue total space) is calculated. The early warning service sets the pause level in the current state by traversing the pause level list according to the calculated percentage of the audio data to be sent. When the Bluetooth blockage early warning service detects that the percentage of data to be transmitted is greater than or equal to 30%, the current Bluetooth transmitting power level of the first gear is improved through a Bluetooth protocol stack, and a command request is issued through the HCI so that the Bluetooth module provides transmitting power. And the Bluetooth headset at the opposite end is informed, and the transmission power level of the Bluetooth headset is also suggested to be synchronously improved. And detecting the current data to be transmitted percentage again, and if the current data to be transmitted percentage is still greater than or equal to 30%, increasing the first-gear Bluetooth transmission power level again until the power level is increased to the maximum value. When the Bluetooth calorie on early warning service detects that the percentage of data to be sent is greater than or equal to 80%, the Bluetooth calorie on state is about to be achieved. The audio coding transmission INTERVAL A2DP _ SBC _ ENCODER _ INTERVAL _ MS is increased from the original 20MS to 30MS by changing the bluetooth protocol stack. If the percentage of pending data is again detected to be less than 80%, the transmission interval is adjusted to the original 20 ms. When the Bluetooth calorie on early warning service detects that the percentage of data to be sent is greater than or equal to 100%, the Bluetooth calorie on state is in a severe calorie on state. The data of the audio transmission queue is backed up first. And then halving the backed-up data, namely saving one frame of data and discarding one frame of data. And finally, backing up the halved data, issuing the data to the Bluetooth module through the HCI, and transmitting the data to the Bluetooth loudspeaker box/earphone of the opposite terminal. The bluetooth katon early warning service continues to detect, and when the percentage is greater than or equal to 100%, the data just cut off is cut off by half again and then sent to the opposite terminal equipment. If the percentage is greater than or equal to 100% a further number of times, then the currently buffered data is discarded.
As can be seen from the above, after acquiring the data transmission request, the embodiment of the present application establishes a bluetooth connection with the receiving device, then, in response to the multimedia data sending operation triggered by the target multimedia, the data to be transmitted corresponding to the target multimedia currently buffered in the Bluetooth transmission queue is monitored, and then, determining a multimedia transmission strategy according to the data proportion of the data to be transmitted in the multimedia transmission queue, and finally, the multimedia data transmission method provided by the application, the multimedia transmission strategy can be determined according to the data proportion of the data to be transmitted in the multimedia transmission queue, and when the transmission code rate is higher, different multimedia transmission strategies can be flexibly switched according to actual conditions, interference caused by wifi or other wireless signals is avoided, and transmission efficiency of multimedia data is improved.
In order to better implement the multimedia data transmission method provided by the embodiment of the application, a multimedia data transmission device is further provided in an embodiment. The terms are the same as those in the above-mentioned multimedia data transmission method, and the details of the implementation can refer to the description in the method embodiment.
