The following detailed description will be given, respectively, with the understanding that the description sequence of the following embodiments is not to be taken as a limitation on the preferred sequence of the embodiments.
Referring to fig. 1b, fig. 1b is a flow chart of a multimedia data transmission method according to the present application. The multimedia data transmission method is applied to the sending equipment, and the specific flow can be as follows:
101. a data transmission request is obtained.
The data transmission request indicates the target multimedia and the receiving device for receiving the target multimedia, the target multimedia may be video or 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.
The bluetooth device can inquire about nearby bluetooth devices and be discovered by nearby bluetooth devices simultaneously in a time division multiplexing mode, namely, a traditional bluetooth device can act as an Inquiring device (inquiry device) and a discoverable device (Discoverable device) simultaneously. The querying device (i.e., the transmitting device) obtains the bluetooth address of the discoverable device by querying.
For example, in response to a user selecting an apparatus for an discoverable apparatus, the selected discoverable apparatus is determined as a receiving apparatus, so that the transmitting apparatus obtains a data transmission request, specifically, the user may click on a data transmission control displayed in the transmitting apparatus, so that the transmitting apparatus obtains the data transmission request, and the style of the data transmission control may be set according to the actual situation
102. A bluetooth connection is established with the receiving device.
Bluetooth is a radio technology supporting short-range communication (typically within 10 m) of devices, enabling wireless information exchange between numerous devices including mobile phones, PDAs, wireless headsets, notebook computers, related peripherals, and the like. By using the Bluetooth technology, the communication between mobile communication terminal devices can be effectively simplified, and the communication between the devices and the Internet can be successfully simplified, so that the data transmission becomes quicker and more efficient, and the road is widened for wireless communication.
Bluetooth is used as a small-range wireless connection technology, and can realize convenient, quick, flexible, safe, low-cost and low-power consumption data communication and voice communication among devices, so that the Bluetooth is one of the mainstream technologies for realizing wireless personal area network communication. Connecting to other networks may lead to a wider range of applications. The wireless communication system is an open-ended wireless communication system, can enable various digital devices to communicate wirelessly, is one of wireless network transmission technologies, and is originally used for replacing infrared communication.
Bluetooth is an open global specification for wireless data and voice communications, which is based on low cost short range wireless connections to establish a special connection for the fixed and mobile device communication environment. The essence is to establish a general radio air interface (Radio Air Interface) for the communication environment between fixed devices or mobile devices, and to further combine the communication technology with computer technology to enable various 3C devices to communicate or operate within close range without wires or cables interconnecting. In brief, bluetooth is a technology for transmitting data between various 3C devices using low power radio.
The Bluetooth device can be connected with the nearby Bluetooth device and the nearby Bluetooth device at the same time in a time division multiplexing mode, namely, the Bluetooth device can serve as a connecting device (Connecting device) and a connectable device (Connectable device) at the same time. The connecting device sends connection request (Connection Request) signaling to the connectable device; the connected device may send connection reply (Connection Response) signaling to the connecting device. After the connection is successful, the bluetooth device that initiates the connection (i.e., the transmitting device) becomes the Master (Master) in the network, and the connected bluetooth device becomes the Slave (Slave) in the network.
When detecting the bluetooth connection operation triggered by the user aiming at the receiving equipment, establishing bluetooth connection with the receiving equipment, wherein the bluetooth connection operation can be triggered by clicking a bluetooth connection control, and also can be triggered by an interconnection system between the equipment, and the bluetooth connection operation is specific according to actual conditions and is not described herein.
103. And responding to the multimedia data sending operation triggered by aiming at 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 (File Transfer Protocol, abbreviated as "FTP"), and the data size of the multimedia data is generally large and cannot be timely transmitted to the corresponding receiving device, so in the present application, by detecting the data to be transmitted corresponding to the target multimedia currently buffered in the bluetooth transmission queue, the subsequent determination of the corresponding multimedia transmission policy according to the data buffered in the bluetooth transmission queue is facilitated.
104. And determining a multimedia transmission strategy according to the data duty ratio of the data to be transmitted in the multimedia transmission queue.
According to the data duty ratio of the data to be transmitted in the multimedia transmission queue, a multimedia transmission policy corresponding to the data duty ratio is determined, for example, the multimedia transmission policy corresponding to the data duty ratio is 30% is an a policy, the multimedia transmission policy corresponding to the data duty ratio is 30% is a B policy, the multimedia transmission policy corresponding to the data duty ratio is 70% is a C policy, and in some embodiments, the a policy, the B policy and the C policy are different from each other: the transmitting power of bluetooth in the transmitting device is different, that is, the higher the data duty ratio is, the higher the transmitting power of bluetooth in the transmitting device is, so as to improve the transmission efficiency of multimedia data, that is, the step of determining a multimedia transmission policy according to the data duty ratio of data to be transmitted in a multimedia transmission queue may specifically include:
(11) Calculating the data duty ratio 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 duty ratio.
The corresponding relation between the range intervals and the multimedia transmission strategies can be pre-constructed, for example, when the range interval corresponding to the data ratio is 30-80%, the transmitting power of Bluetooth in the transmitting equipment can be improved; when the range interval corresponding to the data duty ratio is 80-100%, the transmission interval of the data to be transmitted can be reduced; when the range interval corresponding to the data duty ratio 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 of determining the multimedia transmission policy according to the range interval corresponding to the data duty ratio may specifically include:
(21) Acquiring a range interval corresponding to the data duty ratio;
(22) When the range interval corresponding to the data duty ratio is the first range interval, the transmitting power of Bluetooth in the transmitting equipment is improved;
(23) When the range interval corresponding to the data duty ratio is a second range interval, the transmission interval of the data to be transmitted is increased;
(24) And when the range interval corresponding to the data duty ratio 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 respectively support transmission distances of 100m, 10m and 1m, while bluetooth low energy is of no power Class, generally the transmission power is between-21 and 5dBm, in the present application, since the data size of the transmitted multimedia data is large, conventional bluetooth is adopted, where when the range interval corresponding to the data duty ratio is the first range interval, the transmission power of bluetooth in the transmitting device is increased, for example, the transmission power of bluetooth is increased from Class1 to Class2, or the transmission power of bluetooth is increased from Class1 to Class3, which is specifically selected according to the actual situation, and not described herein, and in some embodiments, the step of "increasing the transmission power of 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 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, and the high power design of the Bluetooth is realized.
When the range interval corresponding to the data duty ratio is the second range interval, the transmission interval of the data to be transmitted is reduced, for example, the transmission interval is increased from 20 milliseconds to 30 milliseconds, and of course, other values are also possible.
When the range interval corresponding to the data duty ratio is the third range interval, 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 can be reserved, the data of the even frame in the backup data can be deleted, or the first 30% of the data in the backup data can be reserved, and the setting is specifically performed according to the actual situation, which is not described herein.
105. The target multimedia is transmitted to the receiving device based on the multimedia transmission policy.
For different multimedia transmission strategies, the mode of transmitting the multimedia is different, and the method is as follows:
Based on the improvement of the transmitting power of the Bluetooth in the transmitting device, the target multimedia is transmitted to the receiving device, for example, after the transmitting power of the Bluetooth is improved from Class1 to Class2, the target multimedia is transmitted to the receiving device based on the transmitting power of Class2, so that interference of wifi or other wireless signals is avoided, and the transmission efficiency of multimedia data is improved.
It should be noted that, before the target multimedia is transmitted to the receiving device based on bluetooth with increased transmission power. The method may further detect a data duty ratio of the data to be transmitted in the multimedia transmission queue, and when a range interval corresponding to the data duty ratio of the data to be transmitted in the multimedia transmission queue with the increased power is a first range interval, continuously increasing the transmission power of bluetooth, that is, optionally, in some embodiments, before the step of "transmitting the target multimedia to the receiving device based on the bluetooth with increased transmission power", the method may specifically further include:
(41) After the transmitting power is increased, detecting the data duty ratio of the data to be transmitted in the multimedia transmission queue;
(42) And when the range interval corresponding to the detected data duty ratio is the first range interval, the transmitting power of the Bluetooth in the transmitting equipment and the transmitting power of the Bluetooth in the receiving equipment are increased to the maximum value.
For example, after the transmitting power of bluetooth is increased from Class1 to Class2, when the range interval of the data to be transmitted corresponding to the data duty ratio of the multimedia transmission queue is still the first range interval, the transmitting power of bluetooth is increased from Class2 to Class3, and multimedia data transmission is performed based on the bluetooth with the transmitting power increased to Class 3.
In addition, for the manner based on the increase of the transmission interval of the data to be transmitted, the target multimedia may be transmitted to the receiving apparatus based on the increased transmission interval.
In the manner of clipping the backup data, the target multimedia may be transmitted to the receiving device based on the clipped backup data, where the data of the odd frame in the clipped backup data may be retained, the data of the even frame in the clipped backup data may be 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 of transmitting the target multimedia to the receiving device based on the clipped backup data may specifically include:
(51) The data of the N frame in the cut backup data is reserved, and the data of the (n+1) frame of the cut backup data is deleted to obtain target data, wherein N is a positive integer;
(52) The target multimedia is transmitted to the receiving device based on the target data.
In this way, in practice, the cut backup data is further halved, so as to reduce the data duty ratio in the multimedia transmission queue, thereby improving the transmission speed, in addition, when the target data is transmitted, the data duty ratio of the target data in the multimedia transmission queue can be detected, and when the data duty 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 specifically can be adjusted according to the actual transmission situation. When the data duty ratio of the target data in the multimedia transmission queue is greater than a preset value, the operation of halving the target data is continued until the data duty ratio of the target data in the multimedia transmission queue after clipping is less than the preset value, that is, optionally, in some embodiments, the method may specifically further include:
(61) When the data duty ratio of the target data in the multimedia transmission queue is detected to be larger than or equal to a preset value, reserving the data of the N frame in the target data, and deleting the data of the (n+1) frame of the target data;
(62) Transmitting the target multimedia to the receiving device based on the data of the nth frame in the target data.
According to the application, the corresponding multimedia transmission strategies are determined according to the data duty ratio of the data to be transmitted in the multimedia transmission queue, and different multimedia transmission strategies can be flexibly selected under different application scenes, so that interference caused by wifi or other wireless signals is avoided, and the transmission efficiency of the multimedia data is further improved.
For further understanding of the multimedia data transmission method of the present application, a video will be taken as an example for further details, refer to fig. 1c, where a bluetooth link is established when a TV end and a bluetooth device end (speaker/earphone) are connected in a binding manner. The TV-side application plays video/music and the TV audio service starts transmitting an audio stream to the opposite bluetooth device. The audio signal is transmitted to the Bluetooth headset at the opposite end, and the corresponding audio coding is carried out according to the coding format negotiated by the two parties through the Bluetooth protocol stack. And finally, sending the audio data to the opposite terminal equipment through the HCI. And the opposite terminal equipment decodes the audio and plays the audio after receiving the audio data. According to the scheme, when the Bluetooth protocol stack performs audio coding, the audio transmission can be dynamically optimized and adjusted by starting the card breakage early warning service. When the TV end application plays video/music and starts audio streaming, a play audio broadcast event is sent. When the system receives the broadcast event, the Bluetooth cartoon early warning service is started. The service runs in real time in the background and collects data information of the tx_audio_queue audio transmission queue of the bluetooth protocol stack. The data information includes the maximum space of the queue, the currently used space of the queue, the number of frames of data the queue has discarded, and the corresponding time stamp. From this data, the percentage of audio data to be sent (space used for queue/total space for queue) is calculated. The early warning service sets the cartoon grade in the current state by traversing the cartoon grade list according to the calculated percentage of the audio data to be sent. When the Bluetooth cartoon early warning service detects that the percentage of the data to be sent is greater than or equal to 30%, the current Bluetooth transmitting power level of a first file is improved through a Bluetooth protocol stack, and a command request is issued through an HCI, so that the Bluetooth module provides transmitting power. And the opposite Bluetooth headset is informed, and the transmitting power level of the Bluetooth headset is also suggested to be synchronously improved. And detecting the current data percent to be transmitted again, and if the current data percent to be transmitted 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 cartoon early warning service detects that the percentage of the data to be sent is greater than or equal to 80%, the Bluetooth cartoon early warning service is in a cartoon-impending state. The transmission INTERVAL a2dp_sbc_code_interval_ms is increased from the original 20MS to 30MS by changing the audio coding of the bluetooth protocol stack. If the percentage of the data to be transmitted is detected again to be less than 80%, the transmission interval is adjusted to be 20ms. When the Bluetooth cartoon early warning service detects that the percentage of the data to be sent is more than or equal to 100%, the Bluetooth cartoon early warning service is in a serious cartoon state. The data of the audio transmission queue is first backed up. And then halving and cutting the backed-up data, namely saving one frame of data and discarding one frame of data. And finally, backing up half of cut data, and transmitting the data to the Bluetooth module through the HCI to be transmitted to the Bluetooth sound box/earphone at the opposite end. The bluetooth jam early warning service can continue to detect, and when the bluetooth jam early warning service is still in percentage more than or equal to 100%, the data which is just cut is cut in half again, and then the data is sent to the opposite terminal equipment. If the percentage is greater than or equal to 100% more times later, the current buffered data is discarded.
As can be seen from the foregoing, after the data transmission request is obtained, the embodiment of the present application establishes a bluetooth connection with a receiving device, then, in response to a multimedia data sending operation triggered by a target multimedia, monitors data to be transmitted corresponding to the target multimedia currently buffered in a bluetooth transmission queue, then, determines a multimedia transmission policy according to a data duty ratio of the data to be transmitted in the multimedia transmission queue, and finally, transmits the target multimedia to the receiving device based on the multimedia transmission policy.
In order to facilitate better implementation of the multimedia data transmission method provided by the embodiment of the application, an embodiment of the application also provides a multimedia data transmission device. Wherein the meaning of the nouns is the same as in the above-mentioned multimedia data transmission method, and specific implementation details can be referred to the description in the method embodiment.
