Recording is easier to process.

Embodiment 2

Referring to FIG. 2 , a flow chart of steps of a recording and broadcasting method according to Embodiment 2 of the present invention is shown. The recording and broadcasting method of the embodiment of the present invention can be applied to a recording and broadcasting system.

The recording and broadcasting method in the embodiment of the present invention may include the following steps:

Step 201, before the video conference starts, receive the recording information sent by the conference control software, and save the recording information, and the recording information includes the identification information of the client to be recorded and the corresponding information of the client to be recorded. Recording parameters.

Conference control software is used to centrally control video conferences. The conference control software can provide a user interface, and the administrator can set the recording information on the user interface before the video conference starts. The recording information may include identification information of the client to be recorded and recording parameters corresponding to the client to be recorded.

The client to be recorded and broadcast refers to the client that allows recording, and there can be one or more clients to be recorded and broadcasted. For example, if it is desired to record the audio and video stream of client A, the identification information of the client to be recorded and broadcast may be the identification information of client A. The recording and broadcasting parameters corresponding to the client to be recorded and broadcasted may include parameters such as recording duration and compression ratio, which are not limited in this embodiment of the present invention.

After setting the recording and broadcasting information, the user can click the "OK" button to trigger the conference control software to send the recording and broadcasting information to the recording and broadcasting system. After the recording and broadcasting system receives the recording and broadcasting information, it saves the recording and broadcasting information.

Step 202: After the video conference starts, an authorization request signaling sent by the current client is received, where the authorization request signaling carries the identification information of the current client.

After the video conference starts, for example, the current client is the speaker client and the current client wants to request to record the audio and video streams of the speech, the current client can generate authorization request signaling and send the authorization to the recording and broadcasting system Request signaling to request the recording and broadcasting system to authorize it.

Step 203 , according to the identification information of the client to be recorded and broadcast and the identification information of the current client, determine whether the current client is the client to be recorded and broadcasted.

After receiving the authorization request signaling sent by the current client, the recording and broadcasting system parses the authorization request signaling to obtain the identification information of the current client carried therein. The recording and broadcasting system can also obtain the identification information of the client to be recorded and broadcasted from the stored recording and broadcasting information.

The recording and broadcasting system compares the identification information of the client to be recorded and the identification information of the current client. If the identification information of the client to be recorded contains the identification information of the current client, it can be determined that the current client is the client to be recorded, otherwise it is determined that the current client is the client to be recorded. The current client is not the client to be recorded.

Step 204: When the current client is the client to be recorded and broadcasted, bind an authorization code to the current client, and return the authorization code to the current client.

If the recording and broadcasting system determines that the current client is the client to be recorded and broadcasted, it can authorize the current client. Pre-set at least one authorization code and save the authorization code to the recording and broadcasting system. The authorization code may be in any applicable form, for example, the authorization code may be in the form of numbers, letters, symbols, or any combination of numbers, letters, and symbols, and the like. The recording and broadcasting system obtains an idle authorization code, that is, an authorization code that is not bound to other clients. The idle authorization code is not null, and the idle authorization code is bound to the current client and bound The authorization code is returned to the current client.

If the recording and broadcasting system determines that the current client is not the client to be recorded and broadcasted, it is not allowed to authorize the current client. In this case, the recording and broadcasting system will not bind the authorization code for the current client, and will not return the authorization code to the current client; or it can bind a null value as the authorization code for the current client, and return the null value authorization code to the current client. current client. The recording and broadcasting system can also record the identification information of the current client in the exception log for subsequent analysis of the recording and broadcasting system.

Step 205: Receive the audio and video stream and the authorization code sent by the current client, and after the authorization code is successfully verified, perform the audio and video stream according to the recording and broadcasting parameters corresponding to the current client. record.

If the current client receives the authorization code returned by the recording and broadcasting system and the authorization code is not null, the current client will obtain the audio and video stream, and return the audio and video stream and the authorization code to the recording and broadcasting system. If the current client does not receive the authorization code returned by the recording and broadcasting system, or receives a null authorization code, the current client will not return the audio and video stream and authorization code to the recording and broadcasting system.

If the recording and broadcasting system receives the audio and video stream sent by the current client and the authorization code, it will verify the received authorization code. During the verification process, the recording and broadcasting system compares the received authorization code with the authorization code previously bound to the current client. If the two authorization codes are the same, the authorization code verification is successful, otherwise the authorization code verification fails.

If the verification of the authorization code is successful, the recording and broadcasting system can determine the identification information of the current client bound to the verification code according to the received verification code, and obtain the identification information from the saved recording and broadcasting information according to the identification information of the current client. Recording parameters corresponding to the current client. The recording and broadcasting system records the audio and video stream according to the recording and broadcasting parameters corresponding to the current client. After recording, the recording and broadcasting system saves the audio and video streams corresponding to the identification information of the current client. If the verification of the authorization code fails, the recording and broadcasting system can record the identification information and authorization code of the current client in the exception log, so as to analyze the recording and broadcasting system later.

If the recording and broadcasting system does not receive the audio and video stream and the authorization code sent by the current client, it will not perform subsequent processing.

Step 206: Receive the recording and broadcasting editing signaling sent by the conference control software, where the recording and broadcasting editing signaling includes the identification information of the client to be edited and the editing type.

The audio and video streams recorded in the recording and broadcasting system can also be edited through the conference control software. When administrators want to edit the recorded audio and video streams of a client, they can select or input the identification information and editing type of the client to be edited on the user interface provided by the conference control software. The conference control software obtains the identification information and editing type of the client to be edited, generates a recording and editing instruction carrying the identification information and editing type of the client to be edited, and sends the recording and editing signaling to the recording and broadcasting system.

Step 207: According to the identification information of the client to be edited, search for the audio and video stream corresponding to the client to be edited from the recorded audio and video streams, and edit the found audio and video stream according to the editing type.

After receiving the recording and broadcasting editing signaling, the recording and broadcasting system parses the recording and broadcasting editing signaling to obtain the identification information and editing type of the client to be edited. After the audio and video streams are recorded, the audio and video streams are stored in correspondence with the identification information of the current client. Therefore, according to the identification information of the client to be edited, the audio and video streams corresponding to the identification information of the client to be edited can be searched from the recorded audio and video streams. video stream.

If an audio and video stream corresponding to the identification information of the client to be edited is found, the found audio and video stream is the audio and video stream corresponding to the client to be edited. The recording and broadcasting system edits the found audio and video streams according to the editing type.

If the audio/video stream corresponding to the identification information of the client to be edited is not found, the recording and broadcasting system may return the first error response signaling to the conference control software, where the first error response signaling is used to indicate that the to-be-edited client is not found. Edit the audio and video streams corresponding to the client. The recording and broadcasting system may also record the identification information of the client to be edited into the exception log, so as to analyze the recording and broadcasting system later.

In this embodiment of the present invention, the editing type may include at least one of the following: recall and delete.

For example, if the editing type is retrieval, after finding the audio and video stream corresponding to the client to be edited, the recording and broadcasting system can return the audio and video stream corresponding to the client to be edited to the conference control software for The administrator checks the audio and video streams corresponding to the client to be edited on the conference control software. If the editing type is deletion, after finding the audio and video stream corresponding to the client to be edited, the recording and broadcasting system can delete the saved audio and video stream corresponding to the client to be edited. If the editing type is retrieval and deletion, after finding the audio and video stream corresponding to the client to be edited, the recording and broadcasting system can return the audio and video stream corresponding to the client to be edited to the conference control software, and send The audio and video streams corresponding to the client to be edited saved by itself are deleted.

Step 208: Receive information deletion signaling sent by the conference control software, where the information deletion signaling includes identification information of the client to be deleted.

The recording information saved in the recording and broadcasting system, that is, the recording information set before the start of the video conference, can also be deleted through the conference control software. When the administrator wants to delete the recording information corresponding to one or more clients in the set recording information, he or she can select or input the identification information of the client to be deleted on the user interface provided by the conference control software. The conference control software acquires the identification information of the client to be deleted, generates an information deletion signaling carrying the identification information of the client to be deleted, and sends the information deletion signaling to the recording and broadcasting system.

Step 209: Delete the identification information of the client to be deleted and the recording parameters corresponding to the client to be deleted from the recording and broadcasting information.

After receiving the information deletion signaling, the recording and broadcasting system parses it to obtain the identification information of the client to be deleted. The recording and broadcasting system obtains the identification information of the client to be recorded and broadcasted from the saved recording and broadcasting information, and compares the identification information of the client to be recorded and broadcasted with the identification information of the client to be deleted. If the identification information of the client to be deleted exists in the identification information of the client to be deleted, the recording system deletes the identification information of the client to be deleted and the recording parameters corresponding to the client to be deleted from the recording information. If the identification information of the client to be recorded does not exist in the identification information of the client to be deleted, the recording system may return a second error response signaling to the conference control software, where the second error response signaling is used to indicate that the to-be-deleted client does not exist. Delete the recording information corresponding to the client. The recording and broadcasting system may also record the identification information of the to-be-deleted client terminal in the exception log, so as to analyze the recording and broadcasting system later.

Step 210: Find out whether there is an authorization code bound to the client to be deleted.

Step 211 , when there is, unbind the client to be deleted and the authorization code bound to the client to be deleted.

Since the client to be deleted may or may not be bound with an authorization code, the recording and broadcasting system deletes the identification information of the client to be deleted and the corresponding identification information of the client to be deleted from the recording and broadcasting information. After recording and broadcasting parameters, it is also possible to check whether there is an authorization code bound to the client to be deleted.

If there is an authorization code bound to the client to be deleted, since after the identification information of the client to be deleted is deleted, subsequent authorization to the client to be deleted will not be allowed, and the client to be deleted does not need to continue to bind the authorization code, Therefore, the recording and broadcasting system unbinds the authorization code bound to the to-be-deleted client and the to-be-deleted client, so as to recover the authorization code bound to the to-be-deleted client, and the authorization code can be combined with other clients later. end binding. If there is no authorization code bound to the client to be deleted, the recording and broadcasting system may not perform processing.

In this embodiment of the present invention, after the audio and video streams of the client are recorded, the recorded audio and video streams can also be edited. Delete the saved recording and broadcasting information, so that you can control which clients are no longer authorized, and recycle the authorization codes that do not need to be bound in time.

In video networking, devices communicate through video networking MAC addresses, terminal numbers and other information.

Referring to FIG. 5 , a schematic diagram of device interaction in a recording and broadcasting process according to Embodiment 5 of the present invention is shown. It should be noted that some devices are not shown in FIG. 5 , which will be introduced in detail below.

As shown in Figure 5, the recording and broadcasting process may include:

Step 1. Enter the identification information of the client to be recorded and broadcasted.

Before the video conference starts, click the input button through Pamir (Pamir in Figure 5 refers to the conference control software, which can be 16-bit or 64-bit), and initiate filling in the client to be recorded and broadcasted (the client to be recorded and broadcast can be Pocket Connect or On the web page, the handheld communication refers to the signaling of the identification information of the APP of the mobile terminal, and the identification information of the client to be recorded and broadcasted is filled in. Based on the video networking protocol, Pamir packages the identification information of the client to be recorded and broadcasted, and adds the identification information of the recording and broadcasting system to the data packet. Pamir sends the data packet to the video network server (not shown in Figure 5), and then the video network The server forwards the data packet to the recording and broadcasting system according to the identification information of the recording and broadcasting system. After receiving the data packet, the recording and broadcasting system parses it, and stores the identification information of the client to be recorded and broadcasted in the database. Wherein, the identification information may include at least one of the following information: a network MAC address, an IP (Internet Protocol, Internet Protocol) address, a terminal number, and other information.

Step 2. Set the recording and broadcasting parameters.

Initiate the signaling of adding new recording and broadcasting parameters through Pamir, and fill in the recording and broadcasting parameters (the recording and broadcasting parameters are associated with the client to be recorded and broadcast). Pamir packages the recording and broadcasting parameters based on the video networking protocol, and adds the identification information of the recording and broadcasting system to the data packet. Pamir sends the data packet to the video networking server, and then the video networking server forwards the data packet according to the identification information of the recording and broadcasting system. to the recording system. After receiving the data packet, the recording and broadcasting system parses it, and stores the recording and broadcasting parameters in the database in association with the identification information of the client to be recorded and broadcasted, so as to authorize the recording and broadcasting later. The recording and broadcasting parameters may include at least one of the following: recording and broadcasting time, video size, compression ratio, and the like.

It should be noted that, with regard to the above steps 1 and 2, Pamir can fill in the identification information and recording parameters of the client to be recorded and broadcast at one time, and package and send them together. The packaging and sending process is basically the same as the above-mentioned packaging and sending process.

Step 3. Obtain authorization.

After the video conference starts, the PDA or the web terminal (the PDA or the web terminal in Figure 5 refers to the current client) generates authorization request signaling based on the Internet protocol, and the authorization request signaling may include the PDA or the web terminal (also That is, the identification information of the current client), and may also include the identification information of the recording and broadcasting system. Since the PDA and the web terminal belong to the clients in the Internet, if they want to access the Internet of Views, they must go through a protocol conversion gateway (not shown in FIG. 5 ) to perform protocol conversion. Therefore, the PDA or the web terminal sends the authorization request signaling based on the Internet protocol to the protocol conversion gateway, and the protocol conversion gateway converts the authorization request signaling based on the Internet protocol into the authorization request signaling based on the Internet protocol. In implementation, the protocol transition gateway may add the Internet of View protocol packet header to the Internet Protocol-based authorization request signaling to obtain the Internet of View protocol-based authorization request signaling. The video networking protocol packet header may include information such as the source MAC address (the video networking MAC address of the protocol conversion gateway) and the destination MAC address (the video networking MAC address of the recording and broadcasting system). The protocol conversion gateway sends the authorization request signaling based on the Internet-of-view protocol to the Internet-of-view server, and the Internet-of-view server forwards the authorization request signaling based on the Internet-of-view protocol to the recording and broadcasting system according to the identification information of the recording and broadcasting system.

Step 4. Return the authorization code.

After receiving the authorization request signaling, the recording and broadcasting system parses it, obtains the identification information of the mobile phone or the web page, and compares the identification information of the mobile phone or the web page with the identification information of the client to be recorded and broadcast entered in step 1. If they are the same, the recording and broadcasting system is bound to the authorization code for the handheld communication or the web page. The recording and broadcasting system encapsulates the authorization code based on the video networking protocol, and adds the identification information of the handheld communication or the web page and the identification information of the protocol conversion gateway. The identification information returns the authorization code to the corresponding protocol conversion gateway, the protocol conversion gateway converts the Internet protocol to the Internet protocol, and the protocol conversion gateway returns the authorization code to the PDA or the web terminal. If not, the recording and broadcasting system returns a null authorization code or no information according to the above process, records the relevant information of the authorization request signaling, and stores it in the exception log of the intelligent recording and broadcasting service system.

Step 5, audio and video streaming transmission.

After receiving the authorization code, the mobile phone or the web terminal encapsulates the audio and video stream and the authorization code based on the Internet protocol, and can also encapsulate the identification information of the mobile phone or the web terminal and the identification information of the recording and broadcasting system. The PDA or the web terminal sends the data packets encapsulated based on the Internet protocol to the protocol-transformation gateway, and the protocol-transformation gateway converts the data packets encapsulated based on the Internet protocol into data packets encapsulated based on the Internet protocol. In implementation, the protocol-transition gateway may add the Internet-of-view protocol packet header to the data packet encapsulated based on the Internet protocol to obtain the data packet encapsulated based on the Internet-of-view protocol. The video networking protocol packet header may include information such as the source MAC address (the video networking MAC address of the protocol conversion gateway) and the destination MAC address (the video networking MAC address of the recording and broadcasting system). The protocol conversion gateway sends the data packets encapsulated based on the Internet-of-view protocol to the Internet-of-view server, and the Internet-of-view server sends the data packets encapsulated based on the Internet-of-view protocol to the recording and broadcasting system according to the identification information of the recording and broadcasting system.

After receiving the data packet, the recording and broadcasting system parses it to obtain the audio and video stream, authorization code, identification information of the mobile phone or the web page, etc., and obtains the authorization previously bound to the mobile phone or the web page according to the identification information of the mobile phone or the web page. code. If there is an authorization code previously bound to the mobile phone or web page, compare the received authorization code with the authorization code previously bound to the mobile phone or the web page. If the two authorization codes are the same, the authorization code will be verified. Success, otherwise the authorization code verification fails. If there is no authorization code previously bound to the mobile phone or web page, the authorization code verification fails. After the verification of the authorization code is successful, the recording and broadcasting system cuts and stores the audio and video streams in combination with the recording and broadcasting parameters set for the handheld communication or the web page in step 1.

Step 6: Send recording and editing signaling.
