DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the invention as recited in the appended claims.

FIG. 1A is a flow chart of a video communication method, according to an exemplary embodiment. FIG. 1B is a scenario where the video communication method can be used, according to an exemplary embodiment. The video communication method may be implemented by a terminal device such as a smart phone, a tablet computer, or a desktop computer. As shown in FIG. 1A, the video communication method includes the following steps S101-S103.

In step S101, when a video communication between the terminal device and a peer device of the terminal device is in progress, whether or not to switch a video image for the video communication is determined.

In an embodiment, the terminal device may conduct the video communication with the peer device via Internet, or may conduct the video communication with the peer device via a mobile communication network such as a 3G or 4G communication network. In an embodiment, the video image for the video communication may be switched by a first instruction message received from the peer device, wherein the first instruction message may be provided by a user of the peer device according to his/her requirement. In another embodiment, the video image may be switched by a second instruction message in the terminal device, wherein the second instruction message may be generated by a user of the terminal device operating the terminal device according to an instruction provided by the user of the peer device.

In step S102, when it is determined to switch the video image, the video image for the video communication is switched from a first video image acquired by the terminal device to a second video image acquired by a designated smart device. The designated smart device is communicatively coupled to the terminal device.

In an embodiment, the designated smart device may be designated by the peer device, or may be designated by the terminal device, particularly, may be determined by the user of the terminal device or the user of the peer device according to specific requirements. In an embodiment, the number of the smart device communicatively coupled with the terminal device via a local area network may be one, or may be two or more. In an embodiment, different smart devices may be provided at different locations, thereby video images in different directions or spaces may be acquired, and the terminal device may record respective identities of the smart devices and their positions in a list.

In step S103, the second video image is sent to the peer device.

In an embodiment, the network used for sending the second video image to the peer device can be determined according to a type of the network for the video communication between the terminal device and the peer device. For example, when the video communication can be conducted between the terminal device and the peer device only via the 3G or 4G communication network, in order to ensure normal communication therebetween, the second video image may be sent to the peer device via the 3G or 4G communication network. Moreover, when the video communication may be conducted between the terminal device and the peer device via Internet, the second video image may be sent to the peer device via Internet. In this way, the cost of network communication for the terminal device is reduced.

Hereinafter, illustration to the present disclosure is given with reference to FIG. 1B. As shown in FIG. 1B, when it is detected that a smart phone 11 has accessed to Internet, and a video communication is in progress between a user using the smart phone 11 and a user using a desktop computer 12, the smart phone 11 may first detect a type of the communication connection with a smart camera 131 and a smart camera 132. If the smart phone 11 detects that the smart phone 11 is connected with the smart camera 131 and the smart camera 132 via a local area network, when the smart phone 11 needs to switch a video image for the video communication with the desktop computer from a first video image to a second video image acquired by either of the smart camera 131 and the smart camera 132, the smart phone 11 may acquire the second video image from the smart camera 131, and then send the second video image to the desktop computer 12 via Internet or a 3G or 4G communication network. In this case, the smart camera 131 and the smart camera 132 do not need to access to Internet or the 3G or 4G communication network, and video images acquired by different smart devices may be flexibly switched in the smart phone 11.

In another embodiment, if the smart phone 11 detects that the smart mobile phone 11 is not connected with the smart camera 131 via the local area network, the smart phone 11 may determine a type of a communication connection which may be established with the smart camera 131. For example, if the smart phone 11 detects that the communication connection with the smart camera 131 may be established via the 4G communication network, then the smart phone 11 may receive the video image from the smart camera 131 via the 4G communication network, thereby ensuring that the user of the peer device can view the video image acquired by the smart camera 131. Similarly, if the smart phone 11 detects that the communication connection with the smart camera 131 may be established via Internet, then the smart phone 11 may receive the video image from the smart camera 131 via Internet, thereby ensuring that the user of the peer device can view the video image acquired by the smart camera 131. Still similarly, if the smart phone 11 detects that the communication connection with the smart camera 131 may be established via the 3G communication network, then the smart phone 11 may receive the video image from the smart camera 131 via the 3G communication network, thereby ensuring that the user of the peer device can view the video image acquired by the smart camera 131.

In the present embodiment, when it is determined to switch the video image, the video image for the video communication is switched from the first video image acquired by the terminal device to the second video image acquired by the designated smart device. In this way, the video image acquired by the designated smart device may be flexibly switched at the terminal device side, and the video images of the terminal device side displayed by the peer device may be flexible as well, which facilitates the user of the peer device to view the video images acquired by different smart devices at the terminal device side, and improves the flexibility of presenting different video sources.

In an embodiment, determining whether or not to switch the video image for the video communication may include: detecting whether a first instruction message from the peer device is received; and when the first instruction message is received, determining whether or not to switch the video image for the video communication according to the first instruction message.

In an embodiment, determining whether or not to switch the video image for the video communication according to the first instruction message may include: detecting a first operation triggered by the first instruction message; and when the first operation triggered by the first instruction message is detected, determining to switch the video image for the video communication.

In an embodiment, determining whether or not to switch the video image for the video communication may include:detecting whether a second instruction message from the terminal device is received; and when the second instruction message is received, determining whether or not to switch the video image for the video communication according to the second instruction message.

In an embodiment, switching the video image for the video communication from the first video image acquired by the terminal device to the second video image acquired by the designated smart device may include: determining an identity of the designated smart device; connecting the designated smart device with the terminal device communicatively via a local area network according to an identity of the designated smart device; and switching the video image for the video communication from the first video image acquired by the terminal device to the second video image acquired by the designated smart device according to the identity of the designated smart device.

In an embodiment, sending the second video image to the peer device may include: detecting a type of network for the video communication with the peer device; when it is detected that the communication with the peer device is via a mobile communication network, sending the second video image to the peer device via the mobile communication network; and when it is detected that the communication with the peer device is via Internet, sending the second video image to the peer device via Internet.

The specific implementation of the video communication will be elaborated below with reference to the following embodiments.

For the above methods provided by the embodiments of the present disclosure, the video images acquired by the designated smart devices at the terminal device side can be flexibly switched, such that the video images of the terminal device side displayed at the peer device are flexible as well. It is convenient for the user of the peer device to view the video images acquired by different smart devices at the terminal device side, and the flexibility of presenting different video sources is improved.

Hereinafter, the technical solutions provided by the embodiments of the present disclosure are described with reference to specific embodiments.

FIG. 2 is a flow chart of a video communication method, according to an exemplary first embodiment. The present embodiment is illustrated by utilizing the above methods provided in the embodiments of the present disclosure with reference to the system shown in FIG. 2. In the example, the terminal device receives a first instruction message from the peer device to implement the video communication. As shown in FIG. 2, the method includes the following steps.

In step S201, when a video communication between a terminal device and a peer device of the terminal device is in progress, a first instruction message from the peer device is received.

In an embodiment, the first instruction message from the peer device may be generated by clicking on a relevant key on a video communication software or a video communication application (app) in the peer device by a user, and the terminal device may receive the first instruction message via Internet, or may receive the first instruction message via a 3G or 4G communication network.

In step S202, it is determined whether or not to switch a video image for the video communication according to the first instruction message.

In an embodiment, it is possible to determine that the video image needs to be switched when a first operation triggered by the first instruction message is detected, wherein the first operation may be an operation of confirmation to the first instruction message. For example, in an embodiment, when the first instruction message sent from the peer device is received, a control key of confirmation to the first instruction message will be included in the first instruction message, and then the user of the terminal device may click on the confirmation control key to confirm that the video image needs to be switched. For another example, the first instruction message may also include a control key for rejecting the first instruction message, and the user of the terminal device may click on the rejection control key to confirm that the video image does not need to be switched.

In step S203, when it is determined that the video image needs to be switched, an identity of the designated smart device is determined.

In step S202 and step S203, it is possible to analyze the first instruction message so as to determine whether the first instruction message includes a first request message for switching the video image for the video communication. If the first request message for switching video image is included, it is determined that the video image needs to be switched, and then the identity of the smart device designated by the user of the peer device may be obtained by analyzing the first instruction message.

In step S204, the video image for the video communication is switched from the first video image acquired by the terminal device to the second video image acquired by the designated smart device according to the identity.

For example, as shown in FIG. 1B, the peer device is a desktop computer 12, the desktop computer 12 adds the identity of the smart camera 131 into the first instruction message. Therefore, when the first instruction message is received by the smart phone 11, it may analyze the first instruction message and then determine that the smart device whose video image will be switched to is the smart camera 131.

In step S205, a type of network for the video communication with the peer device is determined. If the video communication with the peer device is via a mobile communication network, then step S206 is performed. If the video communication with the peer device is via Internet, then step S207 is performed.

In an embodiment, the terminal device may not only conduct video communication with the peer device via the mobile communication network, but also may conduct the video communication via Internet. In an embodiment, the mobile communication network may be a network such as a 3G or 4G communication network provided by a network operator.

In step S206, when it is detected that the video communication with the peer device is via a mobile communication network, the second video image is sent to the peer device via the mobile communication network.

In step S207, when it is detected that the video communication with the peer device is via Internet, the second video image is sent to the peer device via Internet.

In an embodiment, when the terminal device side does not access to Internet via a WIFI network, in order to ensure that the user of the peer device can view the scene pictures at the terminal device side and the smart device side, the terminal device may send the second video image to the peer device via the 3G or 4G communication network. When the terminal device side can access to Internet via the WIFI network or a wired network, in order to save the communication cost for the user of the terminal device, the terminal device may send the second video image to the peer device via Internet.

As an illustrative scenario, as shown in FIG. 1B, the user of the smart phone 11 is at home, and the smart camera 131 and the smart camera 132 are respectively disposed at different rooms of the house of the user of the smart phone 11. A user of a desktop computer 12 may conduct a video communication with the user of the smart phone 11, in order to check respective conditions of the spaces corresponding to the smart camera 131 and the smart camera 132. In this case, the user of the desktop computer 12 may send a first instruction message to the smart phone 11, and the first instruction message carries information indicative of the space of which smart camera is needed to be checked (such as the smart camera 131). After analyzing the first instruction message, if it is detected that a first operation is triggered by the first instruction message, the smart phone 11 may determine that the video image for the video communication needs to be switched, then the smart phone 11 may switch the video image for the video communication from a first video image acquired by the camera device of the smart phone 11 to a second video image acquired by the smart camera 131, thereby the user of the desktop computer 12 can view the image acquired by the smart camera 131.

In addition to the advantageous technical effects of the above embodiments, the present embodiment may switch the first video image currently acquired by the terminal device to the second video image of the smart device designated by the first instruction message using the first instruction message of the peer device, which facilitates the control to the terminal device side by the peer device, and improves autonomy of switching the video scenes of the terminal device side by the user of the peer device.

FIG. 3 is a flow chart of a video communication method, according to an exemplary second embodiment. The present embodiment is illustrated by utilizing the above methods provided in the embodiments of the present disclosure with reference to the system shown in FIG. 1B. In the example, the terminal device side determines a second instruction message to implement the video communication. As shown in FIG. 3, the method includes the following steps.

In step S301, when a video communication between a terminal device and a peer device of the terminal device is in progress, a second instruction message triggered by a user of the terminal device is determined.

In an embodiment, the second instruction message may be generated by clicking on a relevant key on a video communication software or a video communication application (app) provided in the terminal device by a user of the terminal device.

In step S302, whether or not to switch the video image for the video communication is determined according to the second instruction message.

In an embodiment, it is possible to analyze the second instruction message so as to determine whether the second instruction message carries a second request message for switching the video image for the video communication. If the second request message for switching the video image is carried with the message, it is determined that the video image needs to be switched, and then an identity of the smart device designated by the terminal device may be obtained by analyzing the second instruction message.

In step S303, when it is determined that the video image for the voice communication needs to be switched, the video image for the voice communication is switched from a first video image acquired by the terminal device to a second video image acquired by the designated smart device.

The specific description of step S303 may be referred to the above step S102, or the above step S203 to step S204, which is not elaborated herein.

In step S304, the second video image is sent to the peer device.

The specific description of step S304 may be referred to the above step S103, or the above step S205 to step S207, which is not elaborated herein.

As an illustrative scenario, as shown in FIG. 1B, it is assumed that the terminal mobile phone is the smart phone 11, the user of the smart phone 11 is at home, and the smart camera 131 and the smart camera 132 are respectively disposed at different rooms of the house of the user of the smart phone 11. When a user of a desktop computer 12 conducts a video communication with the user of the smart phone 11, if the user of the smart phone 11 does not allow the user of the desktop computer 12 to view the first video image acquired by the camera device of the smart phone 11, a second instruction message may be generated by clicking on a relevant key on the smart phone 11, then the smart phone 11 may analyze the second instruction message, and switches the video image for the video communication from the first video image to the second video image designated by the smart phone 11.

In addition to the advantageous technical effects of the above embodiments, the present embodiment switches the first video image currently acquired by the terminal device to the second video image of the smart device designated by the second instruction message using the second instruction message of the terminal device. In this way, when it is inconvenient for the user of the terminal device to allow the user of the peer device to view the scene image acquired by the terminal device, the video image for the video communication can be switched to the second video image, thereby improving the autonomy of switching the video scenes by the user of the terminal device.
