The so-called push technology is a function of transferring data on one terminal to another terminal through user operations.

In the conventional data push method, for example, when the user wants to push the picture 1 to the terminal B through the terminal A, the picture 1 needs to be selected first, and then the terminal A initiates a search through the terminal A. Usually, terminal A searches for many terminals including terminal B. At this time, the user selects the terminal B, and the terminal A establishes a data transmission link with the terminal B, and pushes the picture 1 to the terminal B through the data transmission link terminal A. After the push is completed, the data transmission link between terminal A and terminal B is immediately disconnected. If the user wants to continue to push the picture 2 to the terminal B through the terminal A, the user needs to re-select the picture 2, and then re-search the terminal B through the terminal A, select the terminal B again and establish a data transmission link with the terminal B again, through data transmission. The link is pushed.

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

When it is determined that the data needs to be transmitted, the first data to be transmitted is acquired, and the first data is sent to the target media output device by using the established data transmission link corresponding to the target media output device, so that the target media output device receives the first data. The first data is output after one data. The mobile terminal includes, but is not limited to, a tablet PC, a smart phone, a feature phone, a PDA, and the like. The media output device is an electronic device having an output module, including but not limited to a device having an output module, such as a television, a laptop computer, a tablet computer, or the like.

In order to facilitate a clearer understanding of the implementation of the present application, the applicant uses a mobile terminal as a mobile phone and a target media output device as a smart television as an example for detailed description.

Based on the mobile terminal side, as shown in FIG. 1 , it shows a flowchart of a data transmission method provided by the present application, including the following steps:

Step 101: Detect a media output device that meets a preset condition under the same local area network as the mobile terminal, and determine at least one media output device as the target media output device in the detected media output device.

In this embodiment, the media output device is a device under the same local area network as the mobile terminal, and may include a personal computer, a PAD computer, a smart TV, a smart TV box, and the like in the same local area network. Here, in order to facilitate a better description, the mobile terminal is used as a mobile phone, and the target media output device is a smart TV as an example.

The mobile phone sends a detection signal to the local area network, and uses the detection signal to detect a media output device that meets the preset condition under the same local area network as the mobile phone. The media output device that meets the preset condition herein refers to a media output device that can establish a data transmission link with the mobile phone and exchange information. After the mobile phone detects the media output device that can be connected, it determines at least one of the media output devices as the target media output device.

Specifically, determining that the at least one media output device is the target media output device may include: after the mobile phone detects the media output device that can be connected, displaying all the detected devices through the display screen for the user to select. Which media output device is selected by the user, the mobile phone determines that the media output device is the target media output device, and all subsequent data interaction objects are all the target media output devices; or, the mobile phone determines all the media output devices detected as targets. The media output device; or, the mobile phone sequentially determines a plurality of, for example, three according to the detected media output device, and determines that the first three media output devices detected first are the target media output devices; or according to the user setting, The media output device that meets the user setting rules is the target media output device.

In this embodiment, the mobile phone finds and displays to the user through all the media output devices in the same local area network as the mobile phone, and the user determines that the smart TV is the target media output device from all the media output devices.

Step 102: Acquire device information of the target media output device, where the device information includes at least a physical address of the target media output device, and send a communication connection request to the target media output device by using the physical address of the target media output device included in the device information. The media output device establishes a data transmission link. The data transmission link established with the target media output device is used to transmit data and maintain a continuous connection state.

In this embodiment, acquiring device information of the target media output device may include: receiving the target The broadcast information sent by the media output device, where the broadcast information includes device information of the target media output device. Or, the mobile device scans the target media output device in the local area network to directly obtain the physical identifier of the target media output device, and obtains the device information according to the physical identifier.

After selecting the smart TV as the target media output device, the user continues to obtain the device information of the smart TV, wherein the device information includes at least the physical address of the smart TV. The physical address of the target media output device may be an IP address of the device, a MAC (Media Access Control), or the like. The mobile phone uses the physical address of the smart TV to send a communication connection request to the smart TV to establish a data transmission link with the smart television and transmit the data through the data transmission link.

It should be noted that, in this embodiment, after the mobile terminal establishes a data transmission link with the target media output device, the data transmission link is kept in a continuous connection state. Specifically, if the mobile terminal A establishes a data transmission link with the target media output device B, the mobile terminal A transmits the data through the data transmission link every time the target media output device B transmits data, and each of the mobile terminal A When the data transmission is completed, the data transmission link is still in a connected state, waiting for the mobile terminal A to use the data transmission link to perform data transmission to the target media output device B again.

Step 103: When it is determined that the data needs to be transmitted, obtain the first data to be transmitted, and send the first data to the target media output device by using the established data transmission link corresponding to the target media output device, so that the target media output device is The first data is output after receiving the first data.

Wherein, when a preset user operation is detected, it is determined that data needs to be transmitted. The preset user operations may include a preset key input operation, a tilt operation, an analog mouse input operation, or a preset gesture input operation.

The transmitting the first data to the target media output device by using the established data transmission link corresponding to the target media output device may include: using the established data transmission link corresponding to the target media output device to the target The media output device sends the data content of the first data to be transmitted, or sends the address information of the first data to be transmitted to the target media output device by using the established data transmission link corresponding to the target media output device to make the target The media output device acquires the first data by using the address information of the first data.

The first data is data information sent by the mobile device to the target media output device, where To include files, audio streams, video streams, and more.

In this embodiment, the current user wants to send the first data, such as the video A to the smart TV. After the user selects the first data, the mobile phone acquires the first data and detects the preset user operation, and uses the established The data transmission link corresponding to the smart TV sends the first data video A to the smart TV, and the smart TV receives the first data video A and outputs the first data to play the video A.

In addition, when the user determines two or more, or the mobile terminal automatically determines that two or more media output devices are the target media output devices, the mobile terminal may simultaneously transmit data in parallel when performing data transmission. Data is transmitted to a plurality of target media output devices, and data transmission to each target media output device may be implemented one by one by serially transmitting data. The specific transmission mode of the mobile terminal is not limited herein, and any manner in which data transmission can be implemented belongs to the protection scope of the present application.

Obviously, the technical solution disclosed in the present application, after detecting a media output device that meets a preset condition under the same local area network as the mobile terminal, and determining at least one media output device as the target media output device in the detected media output device, Obtaining device information of the target media output device, and transmitting, by using the device information, a communication connection request to the target media output device to establish a data transmission link with the target media output device, wherein the device information includes at least a physical address of the target media output device. When it is determined that the data needs to be transmitted, the first data to be transmitted is acquired, and the first data is sent to the target media output device by using the established data transmission link corresponding to the target media output device, so that the target media output device receives the first data. The first data is output after one data. Therefore, after detecting and determining the target media output device, the present application establishes a data transmission link corresponding to the target media output device, and the data transmission link maintains a continuous connection state. In the subsequent process of transmitting data to the target media output device, the data is directly transmitted to the target media output device by using the established data transmission link. Therefore, when performing multiple data transmissions on the same target media output device, the present application does not require the user to reselect the target media output device to establish a connection each time the transmission is performed, which reduces the user's data transmission each time compared to the conventional push method. All need to re-establish the connection with the target media output device to improve the user experience.

Based on the first alternative embodiment corresponding to FIG. 1 above, referring to FIG. 2, another flowchart of the data transmission method provided by the present application detects media that meets preset conditions under the same local area network as the mobile terminal. Output devices, including:

Step 101A: Detect an electronic device that is in the same local area network as the mobile terminal.

Step 101B: Determine whether the detected electronic device is a universal plug and play UPNP device with a preset identifier, and obtain a first determination result.

In this embodiment, when the mobile terminal detects that the mobile terminal is in the same local area network as the media output device that meets the preset condition, it will spend a large amount of network resources to search all the media output devices in the local area network for the data transmission link. Established, and usually the number of target media output devices required by the user is only one, up to three. The establishment of a data transmission link with all media output devices searched in the local area network not only wastes a lot of network resources, but also causes network congestion and network delay. Based on this, in order to facilitate the mobile terminal to efficiently detect the media output device in the same local area network as the mobile terminal, the mobile terminal can detect the electronic device in the same local area network as the mobile terminal, and determine whether the electronic device has A universal UPNP (Universal Plug and Play) device is preset and the first judgment result is obtained.

Among them, the universal UPNP protocol is a network protocol for facilitating mobile terminals to search for electronic devices. The universal UPNP module is included in the electronic device to be searched by the mobile terminal. In practical applications, each UPNP device has a physical identifier for distinguishing other UPNP devices. The identifier may include attribute information indicating a property of the UPNP device or a user-defined device name or the like. In this embodiment, for example, determining whether the electronic device is a universal UPNP device having a preset identifier may include determining whether the electronic device is a universal UPNP device whose device name is “LeTV”, or determining whether the electronic device is a device name. It includes the universal UPNP device of LeEco.

Step 101C: The obtained first judgment result indicates that when the electronic device is a UPNP device with a preset identifier, it is determined that the media output device that meets the preset condition is detected. If not, return to step 101A.

Specifically, in order to ensure that the media output device established with the mobile terminal is a media output device supporting a transportable data medium transmission protocol, the problem that the mobile terminal cannot establish normal connection with the media output device is avoided. Referring to FIG. 3, the detection is in the same office as the mobile terminal. The media output device that meets the preset condition in the domain network further includes the following steps: when the first determination result indicates that the electronic device is a UPNP device with a preset identifier, step 101D is further performed. Step 101D: Determine whether the detected electronic device that is in the same local area network as the mobile terminal is an electronic device that supports the preset media transmission protocol, and obtain a second determination result.

The electronic device supporting the preset media transmission protocol refers to a device that can receive data information sent by the mobile device and can read and process the received data information. The preset media transmission protocol may be a data communication protocol in a local area network, such as a DLNA (DIGITAL LIVING NETWORK ALLIANCE) network protocol. In this embodiment, for example, the mobile terminal pushes video data to the electronic device, and the electronic device needs to have a module that can receive and read and process the video data. Generally, for a mobile device of the Android Android system, the electronic device should have a DMR (Digital Media Receiver) module for receiving video data sent by the Android system. For mobile devices of the Apple iOS system, the electronic device should have an AirPlay module for receiving video data sent by the Apple iOS system. An electronic device having a DMR module and/or an AirPlay module, respectively, is referred to as an electronic device supporting a preset media transmission protocol.

In step 101E, when the second determination result indicates that the electronic device is an electronic device supporting a preset media transmission protocol, the physical address of the detected UPNP device and the physical address of the electronic device supporting the preset media transmission protocol are acquired.

In step 101F, it is compared whether the physical address of the UPNP device is the same as the physical address of the electronic device supporting the preset media transmission protocol. If they are the same, step 101G is performed. If not, the process returns to step 101A.

In step 101G, it is determined that the media output device that meets the preset condition is detected.

In this embodiment, by performing further verification on the detected media transmission device, when the media transmission device simultaneously satisfies the UPNP device and is a device supporting the preset media transmission protocol, determining that the media transmission device is the target media transmission device, The accuracy of the data transmission link is ensured, that is, the efficiency of data transmission is further ensured.

On the basis of the above embodiments, please refer to FIG. 4, a data transmission method provided by the present application Another flow chart also includes:

Step 104: Save device information of the obtained target media output device.

Step 105: When it is determined that the data needs to be transmitted and it is determined that the data transmission link corresponding to the target media output device is disconnected, the data transmission link is re-established by using the saved device information of the target media output device, and the re-established data transmission link is utilized. Sending the second data to be transmitted to the target media output device. The second data is data information that the mobile device retransmits to the target media output device, and may include a file, an audio stream, a video stream, and the like.

Here, it should be noted that the order of step 104 and the foregoing steps 101-103 is not limited. In the present application, step 104 may be performed after step 103, or may be performed simultaneously with step 103, and is also performed after step 102 acquires device information of the target media output device. The present application is only described as a preferred embodiment in the order of the above steps, and the specific execution order in the actual application process is not limited to the technical solutions disclosed in the present application.

In this embodiment, the mobile terminal saves the acquired device information of the target media output device. Therefore, when determining that the data transmission link currently needs to be transmitted and determining that the data transmission link corresponding to the target media output device is disconnected, the mobile terminal directly re-establishes the data transmission link by using the saved device information of the target media output device, and uses the re-established The data transmission link transmits the second data to be transmitted to the target media output device. Applying the technical solution of the present application, the user does not need to re-detect the search media output device, and re-determines that the target media output device is transmitting data, which facilitates the user operation and improves the user experience.

Based on the media output device side, referring to FIG. 5, another flowchart of a data transmission method provided by the present application includes:

Step 201: Receive a communication connection request sent by the mobile terminal to establish a data transmission link with the mobile terminal.

The data transmission link established with the target media output device is used to transmit data and maintain a continuous connection state. The media output device is a target media output device in the media output device that is detected and determined by the mobile terminal and is in the same local area network as the mobile terminal.
