Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a video synchronization method, a terminal, a color ring platform, a system, and a readable storage medium.
Background
The video calls are classified into internet video calls and mobile network video calls according to the difference of the underlying network. In the internet video call, a user accesses the internet, connects with an opposite terminal through an APP (Application program), and then forwards information such as voice, video and the like through an IP packet on the internet. Currently, there are many social software applications, and the social software application is the most common way to apply video calls.
The mobile network video telephone is characterized in that a user selects a video call function by using a dial pad of a mobile phone and then two ends interact. The video telephone in the mode is interacted through a mobile network, and the reliability is high.
However, since the internet video call depends on the internet, the reliability is low, and the APP needs to be installed and used, the use is complicated; the mobile network video telephone has high reliability, but can not activate the video as required at will.
The Voice over Long-Term Evolution (lte) video color ring service is a service customized by a called subscriber and provides a piece of pleasant, colorful or interesting video media to a calling subscriber to replace a common network ring back tone.
In order to support video color ring, the system needs to inject the media file first, and the file injection only needs to be performed once. At present, there are two media file generation methods for video media: 1. manually braking DIY; 2. a content platform. Although the generation is different, the media file injection paths are basically consistent: the central music platform- > the polyphonic ringtone centralized platform- > the province polyphonic ringtone platform- > the video polyphonic ringtone media file is played.
The playing of the video color ring is a plurality of actions, and the playing path is as follows: provincial color ring platform- > SBC (Session Border Controller) > terminal. Once the called party answers, the system stops playing the video color ring.
From the above, the video media asset file of the video color ring is generated statically; media playing is carried out with stream pushing from the color ring platform every time; the called party answers the video color ring and stops playing.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
In order to facilitate understanding of the embodiments of the present invention, a video color ring and a color ring are first described.
1) From the aspect of function scope, the function scope of the video color ring and the color ring is the inclusion relation. Specifically, the video color ring is the upgrade of the color ring, and can support the playing of videos and the like besides meeting all functions of the color ring.
2) From the perspective of technical support, the technical support of video color ring and color ring is different. In the process of paging a called end by a calling end, compared with a signaling flow of the color ring, at least two processes of media resource capability negotiation and resource reservation are added in the signaling flow of the video color ring.
3) From the aspect of terminal support, the playing of the video polyphonic ringtone requires the capability of the corresponding terminal for supporting the video playing, and the playing of the polyphonic ringtone only requires the capability of the corresponding terminal for supporting the audio playing.
4) From the perspective of core network bearing, the video color ring can allocate a video bearing with the bandwidth of 974Kbps and an audio bearing with the bandwidth of 146 Kbps; and the polyphonic ringtone is only allocated with an audio bearer with the bandwidth of 146 Kbps.
In summary, the video color ring can satisfy all the requirements of the color ring, but the color ring cannot satisfy all the requirements of the video color ring.
It should be noted that, in the embodiment of the present invention, the first terminal may be a calling terminal or a called terminal, and similarly, the second terminal may be a called terminal or a calling terminal. For example, when the first terminal is a calling terminal, the second terminal is a called terminal; or, when the first terminal is a called terminal, the second terminal is a calling terminal.
As shown in fig. 1, an embodiment of the present invention provides a video synchronization method applied to a first terminal, including:
In this step, the calling terminal dials the called terminal, and the calling terminal and the called terminal simultaneously play the video color ring customized by the called or calling party pushed by the color ring platform. Under the condition that a called party is off-hooked (namely under the condition that the first terminal and the second terminal successfully establish a call), the polyphonic ringtone platform stops pushing the video polyphonic ringtone customized by the called party or the calling party; however, in order to ensure the transmission of the subsequent video stream file, the first terminal still maintains the first video resource, i.e. the first terminal does not release the first video resource.
And step 12, pushing the video stream file generated by the screen recording operation to a color ring back tone platform in real time through the first video resource according to the screen recording operation on the first terminal, so that the color ring back tone platform pushes the video stream file to a second terminal in real time.
For example, the video synchronization method provided by the embodiment of the present invention can be applied to the following scenes: the user A is unfamiliar with the operation of the mobile phone, calls the user B, and hopes that the user B can demonstrate how to operate the mobile phone; after the call between the user A and the user B is successfully established, the user B starts a screen recording function and operates on an operation interface of the user B, the whole operation process is recorded, and a video stream file is generated; and transmitting the video stream file to the color ring platform in real time through the first video resource which is not released before, sending the video stream file to the user A by the color ring platform in real time, and playing the video stream file by the terminal side of the user A in real time to realize video synchronization.
Optionally, in the foregoing embodiment of the present invention, the maintaining the first video resource in step 11 includes:
receiving an indication message for maintaining video resources sent by the polyphonic ringtone platform;
and keeping the first video resource according to the indication message.
For example, the polyphonic ringtone platform sends an update message to the first terminal, and if m in the update message is video 0RTP/AVP 97, the first terminal maintains the first video resource according to the update message.
In the traditional video color ring, the video is not played continuously after the call is connected, so that the corresponding video resource needs to be released after the called party goes off the hook. For example, the polyphonic ringtone platform sends an update message to the first terminal, and if m in the update message is video 0RTP/AVP 0, the first terminal releases the corresponding video resource according to the update message.
It should be noted that, in the foregoing embodiment of the present invention, after the called party goes off-hook (that is, after the first terminal and the second terminal successfully establish a call), the first terminal further needs to perform capability update negotiation with the color ring platform, so that the color ring platform obtains the relevant capability of the video supported by the first terminal.
Optionally, in the above embodiment of the present invention, before step 12, the method further includes:
receiving a first input, the first input for triggering a video synchronization function;
and sending a video synchronization starting notification to the color ring platform so that the color ring platform starts a local push streaming function. And if not, the polyphonic ringtone platform cannot push the video stream file to the second terminal.
For example, a "video synchronization" button is added on a display interface of the first terminal, and the first terminal transmits a command for starting a video synchronization notification to the color ring back tone platform through http; for another example, based on the dial-up keypad, the DTMF (Dual-Tone multi frequency) is used to carry the special payload of RTP (Real-time Transport Protocol) to carry the "start video synchronization notification" for transmission; the polyphonic ringtone platform detects the command in an in-band detection mode and executes corresponding operation.
Optionally, when the polyphonic ringtone platform starts the stream pushing function from the home terminal, a matching relationship between the first terminal and the polyphonic ringtone platform and a matching relationship between the polyphonic ringtone platform and the second terminal need to be created, so as to ensure that a subsequent video stream file received from the first terminal can be forwarded to the second terminal.
Accordingly, step 12 comprises:
responding to the first input, and starting screen recording software;
and recording the screen by the screen recording software in real time according to the operation of the user on the first terminal operation interface, and generating the video stream file.
For example, a user clicks "video synchronization" to trigger the screen recording software to be started; at this time, the listening screen of the first terminal rolls up (i.e., the listening screen is hidden). A user clicks an APP on a screen of a first terminal to perform demonstration operation; the screen recording software records the screen in real time, generates a video stream file and stores the video stream file to the local at intervals, for example, every 50ms, the interval storage time can be set at will, and is not limited specifically herein.
Optionally, in the above embodiment of the present invention, the method further includes:
receiving a second input for turning off a video synchronization function;
and sending a video synchronization closing notification to the color ring platform so that the color ring platform stops the stream pushing function from the local end. Wherein, in response to the second input, the screen recording software stops recording the screen.
For example, a "stop video synchronization" button is added on a display interface of the first terminal, and the first terminal transmits a command for closing the video synchronization notification to the color ring back tone platform through http; for another example, based on the dial-up keypad, the DTMF (Dual-Tone multi frequency) is used to carry the special payload of RTP (Real-time Transport Protocol) to carry the "close video synchronization notification" for transmission; the polyphonic ringtone platform detects the command in an in-band detection mode and executes corresponding operation.
Optionally, the polyphonic ringtone platform stops the stream pushing function from the home terminal, and deletes the matching relationship between the first terminal and the polyphonic ringtone platform, and between the polyphonic ringtone platform and the second terminal, which are created before.
In summary, in the above embodiment of the present invention, under the condition that the first terminal and the second terminal successfully establish a call, the first video resource and the second video resource are kept not to be released, and the first terminal pushes the video stream file generated by the screen recording operation of the first terminal to the color ring platform in real time through the first video resource, the color ring platform pushes the video stream file to the second terminal in real time through the second video resource, and the second terminal plays the video stream file in real time; the embodiment of the invention can realize the synchronous playing of the videos of the first terminal and the second terminal based on the resources of the video color ring, expand the application scene of the video color ring and improve the user experience.
As shown in fig. 2, an embodiment of the present invention further provides a video synchronization method applied to a second terminal, including:
In this step, the calling terminal dials the called terminal, and the calling terminal and the called terminal simultaneously play the video color ring customized by the called or calling party pushed by the color ring platform. Under the condition that a called party is off-hooked (namely under the condition that the first terminal and the second terminal successfully establish a call), the polyphonic ringtone platform stops pushing the video polyphonic ringtone customized by the called party or the calling party; however, in order to ensure the transmission of the subsequent video stream file, the second terminal still maintains the second video resource, i.e. the second terminal does not release the second video resource.
And step 22, receiving the video stream file pushed by the polyphonic ringtone platform in real time through the second video resource, and playing the video stream file.
For example, the video synchronization method provided by the embodiment of the present invention can be applied to the following scenes: the user A is unfamiliar with the operation of the mobile phone, calls the user B, and hopes that the user B can demonstrate how to operate the mobile phone; after the call between the user A and the user B is successfully established, the user B starts a screen recording function and operates on an operation interface of the user B, the whole operation process is recorded, and a video stream file is generated; and transmitting the video stream file to a color ring platform through the first video resource which is not released before among the generated video stream files, sending the video stream file to a user A by the color ring platform, and playing the video stream file in real time at the terminal side of the user A to realize video synchronization.
Optionally, in the foregoing embodiment of the present invention, the maintaining the second video resource in step 21 includes:
receiving an indication message for maintaining video resources sent by the polyphonic ringtone platform;
and keeping the second video resource according to the indication message.
For example, the polyphonic ringtone platform sends an update message to the second terminal, and if m in the update message is video 0RTP/AVP 97, the second terminal maintains the second video resource according to the update message.
In the traditional video color ring, the video is not played continuously after the call is connected, so that the corresponding video resource needs to be released after the called party goes off the hook. For example, the polyphonic ringtone platform sends an update message to the second terminal, and if m in the update message is video 0RTP/AVP 0, the first terminal releases the corresponding video resource according to the update message.
It should be noted that, in the foregoing embodiment of the present invention, after the called party goes off-hook (that is, after the first terminal and the second terminal successfully establish a call), the second terminal further needs to perform capability update negotiation with the color ring platform, so that the color ring platform obtains the relevant capability of the video supported by the second terminal.
In summary, in the above embodiment of the present invention, under the condition that the first terminal and the second terminal successfully establish a call, the first video resource and the second video resource are kept not to be released, and the first terminal pushes the video stream file generated by the screen recording operation of the first terminal to the color ring platform in real time through the first video resource, the color ring platform pushes the video stream file to the second terminal in real time through the second video resource, and the second terminal plays the video stream file in real time; the embodiment of the invention can realize the synchronous playing of the videos of the first terminal and the second terminal based on the resources of the video color ring, expand the application scene of the video color ring and improve the user experience.
As shown in fig. 3, an embodiment of the present invention further provides a video synchronization method, which is applied to a color ring platform, and includes:
In this step, the calling terminal dials the called terminal, and the calling terminal and the called terminal simultaneously play the video color ring customized by the called or calling party pushed by the color ring platform. Under the condition that a called party is off-hooked (namely under the condition that the first terminal and the second terminal successfully establish a call), the polyphonic ringtone platform stops pushing the video polyphonic ringtone customized by the called party or the calling party; however, in order to ensure the transmission of the subsequent video stream file, the first terminal still maintains the first video resource, that is, the first terminal does not release the first video resource; the second terminal still holds the second video resource, i.e. the second terminal releases the second video resource.
and step 33, pushing the received video stream file to the second terminal in real time through the second video resource, so that the second terminal plays the video stream file.
For example, the video synchronization method provided by the embodiment of the present invention can be applied to the following scenes: the user A is unfamiliar with the operation of the mobile phone, calls the user B, and hopes that the user B can demonstrate how to operate the mobile phone; after the call between the user A and the user B is successfully established, the user B starts a screen recording function and operates on an operation interface of the user B, the whole operation process is recorded, and a video stream file is generated; and transmitting the video stream file to a color ring platform through the first video resource which is not released before among the generated video stream files, sending the video stream file to a user A by the color ring platform, and playing the video stream file in real time at the terminal side of the user A to realize video synchronization.
Optionally, the above embodiment of the present invention further includes:
and respectively sending an indication message for maintaining the video resource to the first terminal and the second terminal.
For example, the polyphonic ringtone platform sends an update message to the first terminal, and if m in the update message is video 0RTP/AVP 97, the first terminal maintains the first video resource according to the update message. And the polyphonic ringtone platform sends an update message to the second terminal, and the second terminal keeps the second video resource according to the update message if m in the update message is equal to video 0RTP/AVP 97.
It should be noted that, in the foregoing embodiment of the present invention, after the called party goes off-hook (that is, after the first terminal and the second terminal successfully establish a call), the first terminal and the second terminal respectively perform capability update negotiation with the color ring platform, so that the color ring platform obtains the related capability of the video supported by the first terminal and the related capability of the video supported by the second terminal.
Optionally, in the above embodiment of the present invention, before step 32, the method further includes:
receiving a video synchronization starting notification sent by a first terminal;
and starting a local push streaming function according to the starting video synchronous notification. And if not, the polyphonic ringtone platform cannot push the video stream file to the second terminal.
For example, a "video synchronization" button is added on a display interface of the first terminal, and the first terminal transmits a command for starting a video synchronization notification to the color ring back tone platform through http; for another example, based on the dial-up keypad, the DTMF (Dual-Tone multi frequency) is used to carry the special payload of RTP (Real-time Transport Protocol) to carry the "start video synchronization notification" for transmission; the polyphonic ringtone platform detects the command in an in-band detection mode and executes corresponding operation.
Optionally, when the polyphonic ringtone platform starts the stream pushing function from the home terminal, a matching relationship between the first terminal and the polyphonic ringtone platform and a matching relationship between the polyphonic ringtone platform and the second terminal need to be created, so as to ensure that a subsequent video stream file received from the first terminal can be forwarded to the second terminal.
Optionally, in the foregoing embodiment of the present invention, step 33 includes:
converting the received video stream file into a video stream file matched with the capability negotiation result according to the capability negotiation result of the polyphonic ringtone platform and the second terminal;
and pushing the video stream file matched with the capability negotiation result to the second terminal in real time through the second video resource.
Because the capability negotiation is respectively performed between the second terminal and the polyphonic ringtone platform and between the polyphonic ringtone platform and the first terminal, the situation that the capability of the first terminal is inconsistent with the capability of the second terminal may exist, and therefore the polyphonic ringtone platform is required to perform conversion; if the first terminal capability is consistent with the second terminal capability, the conversion step can be omitted, and the polyphonic ringtone platform can directly forward.
Optionally, in the above embodiment of the present invention, after the received video stream file is pushed to the second terminal in real time through the second video resource, the method further includes:
receiving a video synchronization closing notification sent by a first terminal;
and stopping the local terminal stream pushing function according to the video synchronization closing notification.
If the video synchronization stopping button is added on the display interface of the first terminal, the first terminal transmits a command for closing the video synchronization notification to the color ring back tone platform through http; for another example, based on the dial-up keypad, the DTMF (Dual-Tone multi frequency) is used to carry the special payload of RTP (Real-time Transport Protocol) to carry the "close video synchronization notification" for transmission; the polyphonic ringtone platform detects the command in an in-band detection mode and executes corresponding operation.
Optionally, the polyphonic ringtone platform stops the stream pushing function from the home terminal, and deletes the matching relationship between the first terminal and the polyphonic ringtone platform, and between the polyphonic ringtone platform and the second terminal, which are created before.
In summary, in the above embodiment of the present invention, under the condition that the first terminal and the second terminal successfully establish a call, the first video resource and the second video resource are kept not to be released, and the first terminal pushes the video stream file generated by the screen recording operation of the first terminal to the color ring platform in real time through the first video resource, the color ring platform pushes the video stream file to the second terminal in real time through the second video resource, and the second terminal plays the video stream file in real time; the embodiment of the invention can realize the synchronous playing of the videos of the first terminal and the second terminal based on the resources of the video color ring, expand the application scene of the video color ring and improve the user experience.
An embodiment of the present invention further provides a system, which includes: the system comprises a first terminal, a second terminal and a color ring platform;
wherein the first terminal is configured to: under the condition that the first terminal and the second terminal successfully establish a call, a first video resource is kept; the first video resource is a resource for transmitting video color ring between the first terminal and a color ring platform; according to the screen recording operation on the first terminal, the video stream file generated by the screen recording operation is pushed to a color ring platform in real time through the first video resource, so that the color ring platform pushes the video stream file to a second terminal in real time;
the second terminal is configured to: under the condition that the first terminal and the second terminal successfully establish a call, maintaining a second video resource; the second video resource is a resource for transmitting video color ring between the second terminal and the color ring platform; receiving a video stream file pushed by the color ring back tone platform in real time through the second video resource, and playing the video stream file;
the color ring back tone platform is used for: under the condition that the first terminal and the second terminal successfully establish a call, maintaining a first video resource and a second video resource; the first video resource is a resource for transmitting video color ring between the first terminal and a color ring platform; the second video resource is a resource for transmitting video color ring between the second terminal and the color ring platform; receiving a video stream file pushed by a first terminal in real time through the first video resource; and pushing the received video stream file to the second terminal in real time through the second video resource so as to play the video stream file by the second terminal.
To more clearly describe the working principle of the system, the following description is made with reference to fig. 4: wherein, suppose that the first terminal is a called terminal, the second terminal is a calling terminal:
the calling party dials the called party, and the calling party and the called party play the customized video color ring of the called party simultaneously.
1. The called party picks up the phone;
2. the polyphonic ringtone platform respectively carries out capability updating negotiation with the calling party and the called party (the polyphonic ringtone platform stops pushing video polyphonic ringtone);
in the embodiment of the present invention, the video stream needs to be transmitted after the call, so the capability negotiation after the off-hook needs to ensure that the video resource cannot be released, and therefore, the m-video XXX setting in the Update message is valid. At the moment, the calling party and the called party still keep video resources, and subsequent users can transmit videos according to needs.
For example: update message to keep video assets: m-video 0RTP/AVP 97
3. The called terminal clicks video synchronization (the calling tells the called user what help is needed through voice), a starting video synchronization notification is sent to the SBC, and the SBC forwards the starting video synchronization notification to the color ring platform;
4. the polyphonic ringtone platform starts to push flow from the local terminal;
the polyphonic ringtone platform receives the notice of starting the video synchronization, retains information, prepares local resources for the video synchronization, establishes a matching relation between the called terminal and the polyphonic ringtone platform and between the polyphonic ringtone platform and the calling terminal, and ensures that a video stream received from the called terminal subsequently is forwarded to the calling terminal.
5. The called party locally records the screen;
the called party clicks video synchronization and triggers local screen recording software. The called answering screen rolls up. And the called party clicks the APP on the screen to perform demonstration operation. The screen recording software records the screen in real time and stores the screen to the local at intervals, for example, every 50ms, the interval storage time can be set.
6. The called party pushes the stream to the color ring platform;
and monitoring the local video stream file in real time, and pushing the local video stream file to the color ring platform once the generation of a new video file is monitored.
Because the channel of the video color ring currently requires the code rate of the video and the like, the video transcoding is required to be performed according to the conclusion of the negotiation of the previous video capability. In order to maintain the continuity of the video, the listening box needs to perform plug-flow smoothing.
7. The color ring platform performs video processing;
and the polyphonic ringtone platform receives the video stream and transcodes the video stream into a new video stream according to a negotiation conclusion of the platform and the calling party. Because the capability negotiation is respectively performed between the calling party and the polyphonic ringtone platform and between the called party and the polyphonic ringtone platform, inconsistency may exist, and therefore conversion needs to be performed on the polyphonic ringtone platform.
8. The calling party plays a real-time video stream;
9. the called party clicks 'stop video synchronization'; the called party triggers the screen recording software to stop recording the screen.
10. And the color ring platform stops pushing the stream from the home terminal, and deletes the matching relationship between the called party and the color ring platform and between the color ring platform and the calling party.
11. When the called party hangs up, the conversation is ended, and the color ring platform releases video resources and audio resources with the calling terminal and the called terminal.
