Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a method for realizing multi-channel video call, which is applied to terminals, such as intelligent terminals with display screens. When other terminals in the multi-path video call receive a negotiation request sent by a certain terminal in the multi-path video call, the other terminals can select the resolution which is closest to the resolution carried in the negotiation request from a plurality of resolutions stored in the terminal, the other terminals adopt the closest resolution to carry out the video call with the terminal sending the negotiation request, but the other terminals still adopt the original resolution to carry out the video call. Fig. 1 is a flowchart of a method for implementing a multi-channel video call according to an embodiment of the present invention.
As shown in fig. 1, the method for implementing the multi-way video call may include:
in step S101, during the multi-way video call, the first terminal receives a negotiation request sent by the second terminal.
In step S102, in response to the negotiation request, the first terminal performs a video call with the second terminal using the first resolution, and the first terminal performs a video call with other terminals except the second terminal using the second resolution.
The first resolution is the resolution after negotiation, and the second resolution is the resolution before the first terminal receives the negotiation request sent by the second terminal.
In the embodiment of the present invention, in the multi-channel video call process, after receiving a negotiation request sent by a second terminal, a first terminal determines a first resolution that can be currently accepted by the second terminal according to the negotiation request, and then sends the first resolution to the second terminal, where the first terminal performs a video call with the second terminal using the first resolution, that is, sends image data to the second terminal according to a currently negotiated second resolution, and receives the image data of the second resolution sent by the second terminal. Meanwhile, the first terminal and other terminals except the second terminal in the multi-path video call also carry out the video call with the original first resolution, namely, the resolution of the first terminal and other terminals before the negotiation is kept unchanged.
In the embodiment of the invention, firstly, in the process of multi-channel video call, the first terminal receives a negotiation request sent by the second terminal, responds to the negotiation request, and carries out video call with the second terminal by adopting the first resolution after negotiation and carries out video call with other terminals except the second terminal by adopting the second resolution before negotiation. The embodiment of the invention can realize that when the resolution of a certain terminal is reduced in the video call of a multi-path terminal, the terminal can send a negotiation request to other terminals in the video call, other terminals determine the resolution after negotiation according to the negotiation request, the other terminals and the terminal with the reduced resolution adopt the resolution after negotiation to carry out the video call, and the other terminals still adopt the original resolution to carry out the call, so that the resolutions of other terminals are kept unchanged under the condition that the terminal with the reduced resolution does not lose data packets. And the whole process is determined by the terminal, and the flexibility of adjusting the resolution ratio is higher.
The second terminal may transmit the largest image data that it can currently receive or transmit to the first terminal in various forms. The plurality of formats may be in the form of transmitting a bit rate, in the form of transmitting a resolution, or in the form of transmitting other contents. The second terminal may take any of the forms described above to indicate to the first terminal the maximum image data that can currently be received or transmitted. The above transmission of these contents is accomplished by various specific mechanisms corresponding thereto. The following describes, by way of example, the second terminal sending a negotiation request to the first terminal via a specific mechanism.
In a possible embodiment of the present invention, the negotiation request may carry bit rate information of the second terminal and address information of the second terminal. Fig. 2 is a schematic flowchart of a method for determining a negotiated resolution according to an embodiment of the present invention. As shown in the figure, in response to the negotiation request, the first terminal performs a video call with the second terminal using the first resolution, which specifically includes:
in step S201, the first terminal acquires bit rate information of the second terminal.
In the embodiment of the present invention, the first terminal first obtains the bit rate information of the second terminal from the received negotiation request. The Bit Rate information is sent to the first terminal by a TMMBR (temporal Maximum bitrate Request) mechanism of RTCP (Real-time transport Control Protocol) when the second terminal detects that the signal quality of the second terminal changes.
In step S202, the first terminal calculates the resolution of the second terminal from the bit rate information of the second terminal.
In the embodiment of the present invention, the first terminal calculates the resolution of the second terminal according to the bit rate information of the second terminal obtained from the negotiation request.
Where resolution is proportional to bit rate, resolution is bit rate/frame rate.
In step S203, the first terminal compares the resolution of the second terminal with a plurality of resolutions stored in the first terminal to obtain a first resolution.
In the embodiment of the present invention, the first terminal compares the resolution obtained by the above calculation with the stored multiple resolutions, and finds the same or similar resolution as the first resolution after negotiation.
In step S204, the first terminal performs a video call with the second terminal using the first resolution.
In the embodiment of the invention, when the connection is established in the multi-channel video call, each terminal firstly performs image sampling, and caches various resolutions in the terminal according to the acquired image information. When a certain terminal changes the capability of sending and receiving image data due to some factors, other terminals match the most appropriate resolution to the terminal according to the content of the negotiation request, and then directly send the resolution after negotiation to the terminal through other terminals of the address according to the address information of the terminal carried in the negotiation request, or forward the resolution after negotiation to the terminal through a network server. And the other terminals and the terminal adopt the negotiated resolution ratio to carry out video call, and the original resolution ratio is still kept among the other terminals to carry out video call.
According to the embodiment of the invention, the resolution is calculated according to the bit rate information carried in the negotiation request sent by the second terminal, and the first terminal selects the resolution which is the same as or similar to the calculated resolution from a plurality of pre-stored resolutions as the resolution which is used for carrying out video call with the second terminal. The embodiment of the invention stores a plurality of resolutions in the terminal in advance, when the capability of a certain terminal for receiving and sending image data is reduced, other terminals can adapt to the terminal to adjust the resolution, and meanwhile, the terminal with unchanged original resolution and capability of receiving and sending the image data can be used for carrying out video call. On the premise of ensuring that the terminal with the reduced receiving capability does not lose the data packet, the resolution between other terminals is ensured to be unchanged, namely the image definition is not changed due to the reduction of the receiving capability of a certain terminal.
In a possible implementation manner of the present invention, the negotiation request may carry resolution information of the second terminal and address information of the second terminal. Fig. 3 is a schematic flowchart of another method for determining a negotiated resolution according to an embodiment of the present invention. As shown in the figure, in response to the negotiation request, the first terminal performs a video call with the second terminal using the first resolution, which specifically includes:
in step S301, the first terminal acquires resolution information of the second terminal.
In the embodiment of the present invention, the first terminal first obtains the resolution information of the second terminal from the received negotiation request. The resolution information is transmitted to the first terminal by a Session Description Protocol (SDP) mechanism of a Session Initiation Protocol (SIP) when the second terminal detects that the signal quality thereof is deteriorated, that is, the capability of receiving and transmitting image data is degraded.
In step S302, the first terminal compares the resolution information of the second terminal with a plurality of resolutions stored in the first terminal to obtain a first resolution.
In the embodiment of the present invention, the first terminal compares the obtained resolution of the second terminal with a plurality of resolutions cached before, and finds the same or similar resolution as the resolution after negotiation.
In step S303, the first terminal performs a video call with the second terminal using the first resolution.
In the embodiment of the invention, when the multi-channel video call is connected and each terminal carries out image data sampling, various resolutions are cached. When the capability of a certain terminal for sending and receiving image data changes, other terminals can match the most appropriate resolution to the terminal according to the negotiation request sent by the terminal, and according to the address information of the terminal carried in the negotiation request, the other terminals directly send the resolution after negotiation to the terminal through the address information, or forward the resolution after negotiation to the terminal through a network server. The other terminals can adopt the resolution after negotiation to carry out video call with the terminal, and the other terminals still keep the resolution before negotiation to carry out video call.
According to the embodiment of the invention, the resolution of the video call between other terminals and the terminal with the changed capability of receiving and sending the image data is changed through negotiation, and the video call between other terminals still keeps the original resolution. Therefore, on the premise of ensuring that the changed terminal does not lose the data packet, the resolution of other terminals is kept unchanged.
In a possible embodiment of the present invention, before the first terminal performs the video call with the second terminal using the first resolution, the method may further include:
the first terminal acquires address information of the second terminal; and the first terminal sends the negotiated resolution to the second terminal according to the address information of the second terminal.
In the embodiment of the invention, the first terminal acquires the address of the second terminal from the content carried by the negotiation request, and then sends the resolution after negotiation to the second terminal according to the address. And the second terminal carries out video call with the first terminal by adopting the resolution after negotiation.
In a possible implementation manner of the present invention, the method for implementing a multi-channel video call may further include:
when the multi-channel video call is connected, each terminal in the multi-channel video carries out data sampling;
each terminal caches various resolutions according to its own sampling data.
In the embodiment of the invention, each terminal caches a plurality of resolutions according to the own sampling data when the connection is established in the multi-channel video call, so that the terminal can be used when the subsequent resolution is changed. By adopting the mode that the cache has multiple resolutions, each terminal can convert the resolution according to the data receiving and sending capabilities of the terminal, and the resolutions of other terminals are not influenced on the premise of ensuring the image quality of the terminal.
The embodiment of the invention also provides a multi-video call system, in which a plurality of terminals carry out video calls, each terminal can sample image data when the video calls are initially connected, and various resolutions are cached for each terminal according to the image data. Therefore, when a certain terminal changes the capability of sending and receiving image data due to some factors, other terminals can negotiate a resolution according to the negotiation request sent by the terminal to carry out video call with the changed terminal, and the other terminals also adopt the original resolution to carry out video call. The method can ensure that when the video calls of the multi-path terminal are carried out, the video calls can be carried out by adopting various resolutions, and the image resolutions of other terminals are ensured to be kept in the original state on the premise of ensuring that the data packets are not lost by the terminals with the reduced sending and receiving capabilities in the video call process.
Each terminal comprises the following functional modules which are used for carrying out the functions of image sampling, caching a plurality of resolutions, negotiating the resolution, selecting the resolution, sending image data and the like.
And the image sampling module is used for inputting images to the terminal in real time through the image collector.
And the resolution reservation module caches various resolutions in the terminal according to the resolution of the acquired image after the image is acquired.
And the resolution negotiation module negotiates information such as resolution through some specific mechanisms when the video call is initially established or the sending and receiving capabilities of the terminal are changed due to signals and the like.
And the resolution selection module is used for selecting the best resolution from the resolutions cached by the terminal when the resolution after negotiation is obtained.
And the image data sending module is used for sending the selected resolution to the terminal address appointed in the negotiation process.
The functional modules can realize that video calls are carried out by adopting different resolutions in the process of multi-path video calls.
The process of the present invention is described in detail below in a specific embodiment.
As shown in fig. 4 and fig. 5, the resolution diagrams adopted when the three-way video call is initiated and the resolution diagrams adopted when the capability of a certain way of terminal is reduced are respectively shown. The multi-channel video call in the present invention refers to three or more video calls, and the embodiment adopts three channels for description.
First, the three-way terminal includes terminal a, terminal B and terminal C, and terminal A, B, C establishes a multi-party video conference and negotiates an initial resolution, such as 640 × 480, at the initial establishment.
Each terminal will perform image sampling when the video call is established, and after the image sampling, various resolutions suitable for the terminal, such as 160 × 120, 320 × 240, 640 × 480, 720 × 540, etc., are cached in the terminal in advance according to the sampling result. The type and kind of the resolution cached in each terminal may be the same or different, depending on the type of terminal.
The terminal can continuously detect the signal quality change condition of the terminal in the video call process, when the signal quality of a certain terminal is poor, the terminal can send a negotiation request to other terminals through a specific mechanism to inform the other terminal, the maximum bit rate information or the resolution information which can be received by the terminal can be received currently, and the other terminal determines the resolution after negotiation according to the information. If the data sending and receiving capability of the terminal a is reduced, the terminal a sends a negotiation request to the terminal B and the terminal C through a TMMBR mechanism of RTCP, and carries the maximum bit rate that the terminal a can receive in the negotiation request, after the terminal B and the terminal C receive the negotiation request, a proper resolution is calculated according to the bit rate information, and then according to various resolutions cached respectively, the closest resolution is selected as the best resolution, which is the resolution after negotiation, for example, the resolutions after negotiation of the terminal B and the terminal C are both 320 × 240.
And the other terminals send the negotiated resolution to the terminal with the degraded signal quality according to the designated address carried in the negotiation request, the other terminals adopt the negotiated resolution and the terminal with the degraded signal quality to carry out video call, and the resolution of images sent by the other terminals is still unchanged. For example, the terminal B and the terminal C send the negotiated resolution of 320 × 240 to the terminal a according to the address specified by the terminal a in the negotiation request, and then the terminal B and the terminal a perform video call with the resolution of 320 × 240, the terminal C and the terminal a also perform video call with the resolution of 320 × 240, and the terminal B and the terminal C still perform call with the resolution of 640 × 480.
In the embodiment of the invention, when the signal quality of the terminal A is poor, the terminal A performs negotiation with the terminal B and the terminal C, and then performs video call by adopting the negotiated resolution, and the original resolution is still adopted between the terminal B and the terminal C to perform video call. Therefore, on the premise that the terminal A does not lose the data packet, the resolution ratios of the terminal B and the terminal C are guaranteed to be unchanged.

In the embodiment of the invention, in the process of multi-channel video call, when the receiving module receives a negotiation request sent by the second terminal, the executing module responds to the negotiation request, and carries out video call with the second terminal by adopting the first resolution after negotiation, and carries out video call with other terminals except the second terminal in the multi-channel video call by adopting the second resolution before negotiation. That is, only the resolution of the terminal that sends the negotiation request and the other terminals is changed, and the resolution between the other terminals remains unchanged.
