Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the present disclosure provides a method for establishing a data connection, which is applied to an image acquisition device, and as shown in fig. 2, the method for establishing a data connection includes the following steps:
The connection establishment time period information refers to a certain specific time period after the current time when the image acquisition device wants to establish data connection with the image decoding device. For example, if the image capturing apparatus wants to establish a data connection with the image decoding apparatus in a time period of nine am to ten am on 21 st 3/month in 2019, the image capturing apparatus sends a connection invitation message including information of the time period of connection establishment "nine am to ten am on 21 st 3/month in 2019" to the image decoding apparatus.
In practical applications, each image capturing device locally stores an image decoding device list for recording identification information, address information, and the like of all image decoding devices to which the image capturing device can be connected. The image capturing device may send a connection invitation message to one or more image decoding devices in its list of image decoding devices.
In one example, the connection invitation message sent by the image capturing device to the image decoding device may carry information about connection reasons, participants, requirements, and other information that needs to be described, in addition to the time period information for establishing connection. For example, the image capture device may further carry "connect event: a technical conference; the participants: the development department member ".
Before the step of sending the connection invitation message to the image decoding apparatus, the method further includes: receiving control information input by a user; and generating the connection invitation message according to the control information. The control information is control statement information; correspondingly, the step of generating the connection invitation message according to the control information includes: carrying out voice recognition on the control statement information to obtain a keyword; and generating the connection invitation message according to the keyword.
In one example, the image capturing device may receive control statement information input by a user through voice, perform voice recognition on the control statement information to obtain a keyword, convert the control statement information input by the user into a connection invitation message, and send the connection invitation message to a corresponding image decoding device. In practical application, the image capturing device may send a connection invitation message for a specific time period to its corresponding one or more image decoding devices.
For example, a user may input speech directly into an image capture device: all image decoding devices are informed of the 10 o 'clock to 11 o' clock technical meetings in the morning and all research and development personnel are required to participate. And after the image acquisition equipment receives the control statement information, carrying out voice recognition on the control statement information, extracting recognized keywords, and converting the obtained keywords into corresponding connection invitation messages. For example, the connection invitation message converted by the above statement may include the following: "connection time: 10 am to 11 am on day 21 of 3/2019; the connection affair is as follows: a technical example meeting; the participants: the whole developer ".
And step 230, establishing connection with the image decoding device according to the connection request.
In the method for establishing data connection according to this embodiment, the image capturing device automatically establishes connection according to the connection request sent by the image decoding device when the connection invitation message includes the connection establishment time period information. Therefore, automatic establishment of data connection is achieved, and user experience is improved.
The embodiment of the present disclosure provides a method for establishing a data connection, which is applied to an image decoding device, and as shown in fig. 3, the method for establishing a data connection includes the following steps:
Optionally, the connection invitation message may also carry information that needs to be described, such as information and requirements of the party and the party staff of the connection, in addition to the information of the connection establishment time period. For example, the connection invitation message may further carry "connection information: a technical conference; the participants: the development department member ".
In practical application, when a plurality of image acquisition devices send connection invitation messages to the image decoding device, the image decoding device may establish a connection event for each connection invitation message and write the connection event into a local connection event table, and the connection events written into the connection event table are sorted according to the sequence of the connection request time periods.
Specifically, the image decoding apparatus may recognize the message content from the connection invitation message, and may send the corresponding message content, such as: the name of the connection user, the connection time period, the connection affair routing, the requirements of the participants and the like are written into the corresponding connection affair of the connection affair table. The connection event table can be displayed on the image decoding device in a text or graph mode so as to be convenient for a user to view.
Optionally, when receiving the connection invitation message sent by the image capturing device, the image decoding device may further prompt the user to receive a new connection invitation message in an instant message form, and meanwhile, the user may select whether to receive the connection invitation according to an actual situation. Specifically, the image decoding device may prompt the user to receive a connection invitation message through a prompt message; when the user selects to accept the connection invitation message, establishing a connection event in a connection event table according to the connection invitation message; and when the user selects to reject the connection invitation message, generating a corresponding connection rejection message according to the rejection reason input by the user and sending the connection rejection message to the image acquisition equipment.
For example, a selection box may be displayed on the display screen of the image decoding apparatus, asking the user whether to accept or reject the connection invitation, and if the user selects to accept the connection invitation, the image decoding apparatus establishes a connection event for the corresponding connection invitation message and records it in the connection event table. In contrast, if the user selects to reject the connection invitation, the image decoding apparatus may ask the user to add a rejection reason, and then notify the corresponding image capturing apparatus of a corresponding connection rejection message, which is not recorded in the connection event table, accordingly.
In this step, the image decoding device searches the address information of the image acquisition device; and initiating a connection request to an address corresponding to the address information, thereby establishing a connection with the image acquisition device.
In practical applications, the image decoding device may set a start timer for each connection event, and determine whether to trigger an operation of establishing a connection with the corresponding image capturing device by determining whether the start timer is overtime. Specifically, when the start timer is overtime, the image decoding device determines that the connection event reaches the corresponding start time point, and then triggers an operation of establishing a connection with the corresponding image capturing device.
When the end time of the time period is reached, the connection with the image capturing apparatus is ended. Specifically, after the image decoding device establishes a communication connection with the image capturing device, the image decoding device may also set an end timer, and when the connection end time is reached, an operation of disconnecting the connection with the corresponding image capturing device is triggered.
Alternatively, when a preset time point before the connection end time is reached, the image decoding apparatus may also prompt the user for the end time of the conference and ask the user whether to automatically terminate the connection when the end time point is reached. If the user selection is yes, the connection to the respective image acquisition device is automatically terminated when the end point in time is reached. If the user selects no, the connection is not automatically disconnected, but the connection with the image acquisition equipment is manually disconnected by the user; and if the user does not make a selection all the time, repeatedly reminding the user to make a selection according to a preset period before the meeting ending time is reached. Of course, at any time point before the image decoding apparatus and the image capturing apparatus are connected and the connection is disconnected, the user may manually disconnect the connection between the image decoding apparatus and the image capturing apparatus.
Alternatively, in a possible embodiment, a priority may be set in each image decoding apparatus for the image capturing apparatuses to which it is connectable, the priority being used to indicate the importance level of the corresponding image capturing apparatus.
Specifically, when a plurality of image capturing devices send a connection invitation message to the image decoding device and the invited connection time periods overlap, the connection with the image capturing device with the higher priority may be selected in the overlapping time period according to the priority of the image capturing device initiating the connection invitation message. When the time periods of the plurality of connection invitation messages overlap and the priorities of the image acquisition devices sending the corresponding connection invitation messages are the same, the user can be prompted to select the time periods, and the image acquisition devices are determined to be connected with in the overlapping time periods according to the selection of the user.
When the time period for establishing the connection is reached, the image decoding device establishes a communication connection with the corresponding image acquisition device, and receives image data or image and sound data transmitted by the corresponding image acquisition device.
Optionally, in another optional implementation, after the image capturing device sends the connection invitation message, some message contents, for example, connection time, participant information, and the like, may need to be modified, and then a connection invitation message may be sent again to the image decoding device, where the connection invitation message carries an "update invitation" identifier for indicating that the connection invitation message is an update to a previously sent connection invitation message. At this time, the image decoding apparatus deletes the connection event established for the previous connection invitation message and re-establishes a new connection event for the new connection invitation message. If the image acquisition device needs to send other connection invitations to the image decoding device before the previously sent connection invitation is executed, a new connection invitation message can be sent to the image decoding device and carries an 'additional invitation' identifier, and the image decoding device receiving the connection invitation message carrying the 'additional invitation' identifier establishes a new connection event for the connection invitation message carrying the 'additional invitation' identifier and records the new connection event in a connection event table.
In the method for establishing data connection according to this embodiment, the image decoding device establishes a corresponding connection event in the event connection table according to the connection establishment time period information included in the connection invitation message, and sends a connection request to the image capturing device when the start time of the connection establishment time period is reached, so as to automatically establish connection. Therefore, automatic establishment of data connection is achieved, and user experience is improved.
