The embodiment of the present invention is not limited to a specific connection interface, and the connection mode may be a bluetooth connection, a WiFi connection, and/or a wired connection. For example, the first terminal may be used as a server in a home interconnection system, and a plurality of bluetooth interfaces, WiFi interfaces and/or wired interfaces are provided on the first terminal, so that the second terminal and the at least one third terminal may be connected to the first terminal through any interface, respectively, that is, the first terminal may be connected to a plurality of terminal devices simultaneously, including connecting the second terminal and the at least one third terminal, respectively. Particularly, a bluetooth 3.0 interface can be further adopted, the bluetooth 3.0 interface can be compatible with a bluetooth transmission protocol and a WiFi transmission protocol, and a plurality of bluetooth 3.0 interfaces are arranged on the first terminal, so that data transmission based on the bluetooth transmission protocol or the WiFi transmission protocol can be simultaneously performed between the first terminal and a plurality of terminal devices respectively. In the home interconnection system using the first terminal as the server, the data transmission method of the present invention can realize data transmission between the second terminal and the first terminal, between the second terminal and at least one third terminal, and between the third terminal and the first terminal.
It will be appreciated that the request may be a data request or a command request. For example, the second terminal may initiate a data request to the first terminal requesting the first terminal to send picture a to a designated third terminal. Or the second terminal may send a command request to the first terminal to request the first terminal to play the video b, or the second terminal sends a command request to the first terminal, and the first terminal forwards the command request to the third terminal to request the third terminal to open and play the video c.
102. And acquiring target data corresponding to the request according to the target data information.
In an application scenario, if the target data information is the target data; then the obtaining of the target data corresponding to the request according to the target data information is: and acquiring the target data information from the request as the target data. In another application scenario, if the target data information is the identifier of the target data; then the obtaining of the target data corresponding to the request according to the target data information is: and acquiring target data corresponding to the identifier from a storage space of the first terminal or from a network server.
103. And sending the target data to a third terminal corresponding to the request.
Wherein the third terminal information corresponds to two or more third terminals; the sending of the target data to the third terminal corresponding to the request may specifically be: and respectively sending the target data to each third terminal corresponding to the request.
According to the data transmission method provided by the embodiment of the invention, the data and control transmission between the second terminal and the third terminal is realized through the first terminal in a network connection mode that the second terminal and at least one third terminal are respectively connected to the first terminal, and compared with the prior art that only one-to-one data and control transmission between two terminals can be realized, one-to-many or many-to-many data and control transmission can be realized, the interconnection and intercommunication among a plurality of terminal devices are realized, and the user experience is improved.
Example 2
In order to facilitate those skilled in the art to understand the content of the present invention, the present embodiment provides a data transmission method, which is described in conjunction with an actual application scenario. The embodiment of the invention is applied to a home interconnection system, the home interconnection system comprises the first terminal, a second terminal and at least one third terminal, and the second terminal and the third terminal are respectively connected to the first terminal. As shown in fig. 2, the implementation method of the present invention is described by taking an example that a home interconnection system includes two third terminals, where the data transmission method of the present embodiment may include:
201. the second terminal, the third terminal 1 and the third terminal 2 are respectively connected with the first terminal.
The connection establishment sequence of the second terminal, the third terminal 1 and the third terminal 2 with the first terminal is not in sequence. In practical application, because the first terminal plays the role of a server which is simultaneously connected with a plurality of terminal devices, the first terminal can be an electronic device which has strong processing capability, has a stable power supply source, or has an important position in household appliances, such as a television or a computer; the second terminal and the third terminal may be electronic devices with relatively unstable power supply, weak computing power, or relatively minor features in home appliances, such as a mobile phone, a tablet computer, a music player, and the like.
202. The first terminal issues terminal information connected to the first terminal to the second terminal.
For example, in one scenario, if the second terminal establishes a connection with the first terminal before the third terminal 1 and the third terminal 2, at this time, the first terminal is not connected with other terminals, so that the terminal information of other terminals (the third terminal 1 and the third terminal 2) cannot be issued to the second terminal temporarily, and the first terminal may send the terminal information of the third terminal newly establishing a connection to the second terminal every time a new terminal is connected. Or, the second terminal establishes a connection with the first terminal after the third terminal 1 and the third terminal 2, and the first terminal may issue terminal information of other terminals (the third terminal 1 and the third terminal 2) that are currently connected to the second terminal. Of course, the first terminal may also issue the terminal information of the second terminal and the third terminal 2 to the third terminal 1, and similarly, the terminal information of the second terminal and the third terminal 1 may also be issued to the third terminal 2.
The terminal information may be an identifier of the terminal, a terminal name, a terminal type, an IP address of the terminal, or an MAC address of the terminal, and the types of the terminal information include, but are not limited to, the above types, as long as each terminal device connected to the first terminal can be distinguished, and the first terminal can find the corresponding terminal device according to the terminal information, which is not illustrated in the embodiments of the present invention.
It should be noted that, in this embodiment, for convenience of describing a data streaming manner, the second terminal is used as an initiator of data transmission, and the third terminal is used as a receiver of data transmission. In practical application, the second terminal and any one of the third terminals are both peer-to-peer, the data transmission has no fixed flow direction, and any one of the third terminals can also initiate a request to the first terminal, and the first terminal sends the data to the second terminal and/or other third terminals. Therefore, when the second terminal and any one of the third terminals are connected to the first terminal, the first terminal may issue the terminal information currently connected to the first terminal to each terminal device that has established connection, so that each terminal device updates the terminal information available in the home interconnection system.
203. The second terminal presents the connection condition of each terminal in the family interconnection system.
The second terminal may present the connection status of each terminal in the home interconnection system to which the second terminal is currently connected in a graph network form, or present the connection status of the terminal that is currently capable of performing data interaction in other manners such as a list or an icon. For example, as shown in the graph in fig. 4, a first terminal is used as a server node in a home interconnection system, and a second terminal and n other third terminals are currently connected to the server node, so that data transmission can be performed between the first terminal and the n third terminals in the graph.
204. And the second terminal determines the third terminal information and the target data information according to the user selection.
The second terminal may allow the user to select target data to be transmitted, where the target data may be data stored in the second terminal, data in the first terminal, or network data. For example, the target data is data that has been stored in the uplink of the first terminal, then before step 204, the first terminal may also issue data information that has been stored in the first terminal to the second terminal, for example, a name, a type, a feature value, a label, and the like of the data, and the user may determine the target data information through the second terminal.
In addition, the second terminal may also allow the user to select a recipient of the target data as the third terminal information. One third terminal, a plurality of third terminals or all the third terminals can be selected according to the needs of the user.
205. The second terminal sends a request containing the third terminal information and the target data information to the first terminal.
Wherein the third terminal information may include terminal information of at least one third terminal, thereby corresponding to the at least one third terminal. For example, the third terminal information may be the terminal information of the third terminal 1 or the terminal information of the third terminal 2, or the terminal information of both the third terminals 1 and 2 is included, so as to indicate to which third terminal or third terminals the target data needs to be sent by the first terminal. The target data information may be the target data itself stored on the second terminal, or may be an identifier of the target data.
206. And the first terminal acquires target data corresponding to the request according to the target data information in the request.
If the target data information is the identifier of the target data, the first terminal may compare the target data information with the data information stored in the local memory to determine whether the target data is local data, and if the target data is local data, may send the stored target data to the third terminal. Or, the first terminal is connected with a public network in addition to the home internet, so that the target data information can be sent to a network server of the public network, so that the network server can issue the target data to the first terminal.
Of course, if the target data information sent by the second terminal is the target data already stored on the second terminal in step 205, the first terminal may obtain the target data from the received request, so as to send the target data to the third terminal.
Or, the target data information may also be a control command, for example, the second terminal instructs the third terminal 1 to play the video a stored in the third terminal 1, and at this time, the first terminal may send the control command to the third terminal 1 as target data, thereby implementing a one-to-many control method between the second terminal and a plurality of third terminals.
207. And the first terminal sends the target data to a third terminal corresponding to the request according to the third terminal information in the request.
And if the third terminal information is two or more than two third terminals, the first terminal respectively sends the target data to each third terminal corresponding to the request. For example, the third terminal information includes an IP address of the third terminal 1 and an IP address of the third terminal 2, and the first terminal sends the target data to the third terminal 1 and the third terminal 2, respectively, after acquiring the target data.
Further, if the target data included in the request is a control command, the first terminal acquires the control command as the target data and sends the target data to a third terminal corresponding to the request, for example, to the third terminal 1 and the third terminal 2, so that the third terminal 1 and the third terminal 2 execute an operation corresponding to the control command. For example, if the target data information included in the request is a control command for opening the picture a, the third terminal 1 and the third terminal 2 both open the picture a after receiving the request.
It is understood that the embodiment of the present invention can also be compatible with the existing one-to-one data transmission and control manner. For example, the second terminal may transmit data to or perform operation control on the first terminal, and a similar third terminal may transmit data to or perform operation control on the first terminal. The implementation of the one-to-one data transmission method in this embodiment is similar to the conventional one-to-one data transmission method, except that the first terminal may determine whether a target recipient of the request is the first terminal according to third terminal information included in the request after receiving the request, and if the third terminal information indicates that the first terminal or the third terminal information is default, the first terminal locally receives and processes the request; otherwise, the target data corresponding to the request is sent to the third terminal so that the third terminal can receive and process the target data.
208. And the third terminal acquires the target data.
And if the target data is a control command, the third terminal executes the operation corresponding to the control command. Thereby, one-to-many data transmission or operation control from the second terminal to the third terminal 1 and the third terminal 2 is completed.
According to the data transmission method provided by the embodiment of the invention, the data and control transmission between the second terminal and the third terminal is realized through the first terminal in a network connection mode that the second terminal and at least one third terminal are respectively connected to the first terminal, and compared with the prior art that only one-to-one data and control transmission between two terminals can be realized, one-to-many or many-to-many data and control transmission can be realized, the interconnection and intercommunication among a plurality of terminal devices are realized, and the user experience is improved.
