Example one

Referring to fig. 1, a flowchart illustrating steps of a recording and playing method according to a first embodiment of the present invention is shown. The recording and broadcasting method of the embodiment of the invention can be applied to a recording and broadcasting system.

The recording and broadcasting method of the embodiment of the invention can comprise the following steps:

step 101, before a video conference starts, receiving recorded broadcast information sent by conference control software, and storing the recorded broadcast information, wherein the recorded broadcast information comprises identification information of a client to be recorded and broadcast and recorded broadcast parameters corresponding to the client to be recorded and broadcast.

Before the video conference begins, some recorded broadcast information related to recorded broadcast can be set by conference control software. The manager can set the identification information of the client to be recorded and broadcasted and the recording and broadcasting parameters corresponding to the client to be recorded and broadcasted on the conference control software. The client to be recorded and broadcasted can represent a client allowing recording of the audio and video stream collected by the client to be recorded and broadcasted. After the setting is finished, the conference control software sends the recorded broadcast information to the recorded broadcast system, and the recorded broadcast system stores the recorded broadcast information.

Step 102, after a video conference starts, receiving an authorization request signaling sent by a current client, wherein the authorization request signaling carries identification information of the current client.

The current client represents a client requesting recording and broadcasting. For example, the current client may be a speaker client in a video conference.

After the video conference starts, the current client sends an authorization request signaling to the recording and playing system so as to request the recording and playing system to authorize the current client and allow the audio and video stream of the current client to be recorded. The authorization request signaling may carry the identification information of the current client, and the like.

And 103, determining whether the current client is the client to be recorded and broadcasted according to the identification information of the client to be recorded and broadcasted and the identification information of the current client.

And after receiving the authorization request signaling, the recording and broadcasting system acquires the previously stored recording and broadcasting information. According to the identification information of the client to be recorded and broadcast included in the recorded and broadcast information and the identification information of the current client included in the authorization request signaling, whether the current client is the client to be recorded and broadcast can be determined.

And step 104, when the current client is the client to be recorded and broadcasted, binding an authorization code for the current client, and returning the authorization code to the current client.

And if the recording and broadcasting system determines that the current client is the client to be recorded and broadcasted, the current client can be authorized. An authorization code may be provided in the recording and playing system, the authorization code may be bound for the current client, and the authorization code may be returned to the current client.

And 105, receiving the audio and video stream sent by the current client and the authorization code, and recording the audio and video stream according to the recording and playing parameters corresponding to the current client after the authorization code is successfully checked.

And after receiving the authorization code, the current client acquires the audio and video stream acquired by the camera and sends the audio and video stream and the authorization code to the recording and broadcasting system. And the recording and playing system verifies the authorization code, and if the verification is successful, the recording and playing system indicates that the audio and video stream of the current client is allowed to be recorded. Therefore, after the authorization code is successfully verified, the recording and playing system records the audio and video stream according to the recording and playing parameter corresponding to the current client.

In the embodiment of the invention, before the video conference begins, the recording and broadcasting parameters of which the audio and video streams of the client are allowed to be recorded are set in the recording and broadcasting system, after the video conference begins, the client actively requests the recording and broadcasting system for authorization, the recording and broadcasting system determines whether to authorize the client according to the setting, and records the audio and video streams of the client which is authorized according to the set recording and broadcasting parameters, so that the audio and video streams of the client can be automatically and specifically recorded, and the processing process is simpler and more convenient.

Example two

Referring to fig. 2, a flowchart illustrating steps of a recording and playing method according to a second embodiment of the present invention is shown. The recording and broadcasting method of the embodiment of the invention can be applied to a recording and broadcasting system.

step 201, before a video conference begins, receiving recorded broadcast information sent by conference control software, and storing the recorded broadcast information, wherein the recorded broadcast information comprises identification information of a client to be recorded and broadcast and recorded broadcast parameters corresponding to the client to be recorded and broadcast.

Conference control software is used for centrally controlling the video conference. The conference control software may provide a user interface on which the manager may set recording and playing information before the video conference begins. The recorded broadcast information may include identification information of the client to be recorded broadcast and recorded broadcast parameters corresponding to the client to be recorded broadcast.

The clients to be recorded and broadcast refer to clients allowing recording, and the number of the clients to be recorded and broadcast can be one or more. For example, if the audio/video stream of the client a is to be recorded, the identification information of the client to be recorded and played may be the identification information of the client a. The recording and playing parameters corresponding to the client to be recorded and played may include parameters such as recording duration, compression ratio, and the like, which is not limited in the embodiment of the present invention.

After the recording and broadcasting information is set, a user can click a 'confirm' button to trigger the conference control software to send the recording and broadcasting information to the recording and broadcasting system. And after the recorded broadcast information is received by the recorded broadcast system, the recorded broadcast information is stored.

Step 202, after the video conference starts, receiving an authorization request signaling sent by a current client, where the authorization request signaling carries identification information of the current client.

After the video conference starts, for example, the current client is a speaking party client and the current client wants to request to record the audio/video stream that is speaking, the current client may generate an authorization request signaling and send the authorization request signaling to the recording and playing system to request the recording and playing system to authorize the audio/video stream.

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

And after receiving the authorization request signaling sent by the current client, the recording and broadcasting system analyzes the authorization request signaling to obtain the identification information of the current client carried in the authorization request signaling. The recording and broadcasting system can also acquire the identification information of the client to be recorded and broadcasted from the stored recording and broadcasting information.

And the recording and broadcasting system compares the identification information of the client to be recorded and broadcasted with the identification information of the current client, if the identification information of the current client exists in the identification information of the client to be recorded and broadcasted, the current client can be determined to be the client to be recorded and broadcasted, and otherwise, the current client is determined not to be the client to be recorded and broadcasted.

And 204, when the current client is the client to be recorded and broadcasted, binding an authorization code for the current client, and returning the authorization code to the current client.

And if the recording and broadcasting system determines that the current client is the client to be recorded and broadcasted, the current client can be authorized. At least one authorization code is preset and stored in the recording and broadcasting system. The authorization code may be in any suitable form, for example, the authorization code may be in the form of numbers, letters, symbols, or any combination of numbers, letters, symbols, and the like. The recording and broadcasting system obtains an idle authorization code, namely the authorization code which is not bound with other clients, the idle authorization code is not null, the idle authorization code is bound with the current client, and the bound authorization code is returned to the current client.

And if the recording and broadcasting system determines that the current client is not the client to be recorded and broadcasted, the authorization of the current client is not allowed. In this case, the recording and broadcasting system cannot bind the authorization code for the current client and cannot return the authorization code to the current client; or binding a null value as an authorization code for the current client, and returning the null value authorization code to the current client. The recording and broadcasting system can also record the identification information of the current client and the like into an abnormal log so as to analyze the recording and broadcasting system in the following.

And step 205, receiving the audio and video stream and the authorization code sent by the current client, and recording the audio and video stream according to the recording and broadcasting parameters corresponding to the current client after the authorization code is successfully verified.

If the current client receives the authorization code returned by the recording and playing system and the authorization code is not a null value, the current client acquires the audio and video stream and returns the audio and video stream and the authorization code to the recording and playing system. If the current client does not receive the authorization code returned by the recording and playing system or receives the null value authorization code, the current client does not return the audio and video stream and the authorization code to the recording and playing system.

And if the recording and playing system receives the audio and video stream and the authorization code sent by the current client, checking the received authorization code. In the checking process, the recording and broadcasting system compares the received authorization code with the authorization code bound for the current client, if the two authorization codes are the same, the authorization code is checked successfully, otherwise, the authorization code is checked unsuccessfully.

If the authorization code is successfully verified, the recording and broadcasting system can determine the identification information of the current client bound with the verification code according to the received verification code, and acquire the recording and broadcasting parameters corresponding to the current client from the stored recording and broadcasting information according to the identification information of the current client. And the recording and broadcasting system records the audio and video stream according to the recording and broadcasting parameters corresponding to the current client. And the recorded recording and broadcasting system correspondingly stores the audio and video stream and the identification information of the current client. If the authorization code is failed to be checked, the recording and playing system can record the identification information, the authorization code and the like of the current client into the abnormal log so as to analyze the recording and playing system in the subsequent process.

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

Step 206, receiving a recorded broadcast editing signaling sent by the conference control software, where the recorded broadcast editing signaling includes identification information and an editing type of a client to be edited.

And aiming at the audio and video stream recorded in the recording and broadcasting system, the audio and video stream can be edited by the conference control software. When a manager wants to edit the recorded audio and video stream of a certain client, the manager can select or input the identification information and the editing type of the client to be edited on the user interface provided by the conference control software. And the conference control software acquires the identification information and the editing type of the client to be edited, generates a recorded broadcast editing instruction carrying the identification information and the editing type of the client to be edited, and sends the recorded broadcast editing signaling to the recorded broadcast system.

Step 207, according to the identification information of the client to be edited, searching the audio/video stream corresponding to the client to be edited from the recorded audio/video stream, and editing the searched audio/video stream according to the editing type.

And after receiving the recorded broadcast editing signaling, the recorded broadcast system analyzes the recorded broadcast editing signaling to obtain the identification information and the editing type of the client to be edited. After the audio and video stream is recorded, the audio and video stream and the identification information of the current client are correspondingly stored, so that the audio and video stream corresponding to the identification information of the client to be edited can be searched from the recorded audio and video stream according to the identification information of the client to be edited.

And if the 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. And the recording and broadcasting system edits the searched audio and video stream 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 playing system may return a first error response signaling to the conference control software, where the first error response signaling is used to indicate that the audio/video stream corresponding to the client to be edited is not found. The recording and broadcasting system can also record the identification information of the client to be edited and the like into an abnormal log so as to analyze the recording and broadcasting system in the following.

In an embodiment of the present invention, the edit type may include at least one of the following: and (5) calling and deleting.

For example, if the editing type is calling, the recording and playing system may return the audio/video stream corresponding to the client to be edited to the conference control software after finding the audio/video stream corresponding to the client to be edited, so that a manager may check the audio/video stream corresponding to the client to be edited on the conference control software. If the editing type is deletion, the recording and playing system can delete the audio/video stream corresponding to the client to be edited, which is stored by the recording and playing system, after finding the audio/video stream corresponding to the client to be edited. If the editing type is calling and deleting, the recording and playing system can return the audio and video stream corresponding to the client to be edited to the conference control software after finding the audio and video stream corresponding to the client to be edited, and delete the audio and video stream corresponding to the client to be edited stored by the recording and playing system.

And 208, receiving an information deletion signaling sent by the conference control software, wherein the information deletion signaling comprises identification information of the client to be deleted.

The recorded broadcast information stored in the recorded broadcast system, namely the recorded broadcast information set before the video conference, can be deleted through conference control software. When the manager wants to delete the recorded and broadcast information corresponding to one or more clients in the set recorded and broadcast information, the manager can select or input the identification information of the client to be deleted on the user interface provided by the conference control software. And 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, deleting the identification information of the client to be deleted and the recording and broadcasting parameters corresponding to the client to be deleted from the recording and broadcasting information.

And after receiving the information deletion signaling, the recording and broadcasting system analyzes the information deletion signaling to obtain the identification information of the client to be deleted. And the recording and broadcasting system acquires the identification information of the client to be recorded and broadcasted from the stored 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. And if the identification information of the client to be deleted exists in the identification information of the client to be recorded and broadcast, deleting the identification information of the client to be deleted and the recorded and broadcast parameters corresponding to the client to be deleted in the recorded and broadcast information of the recorded and broadcast system. If the identification information of the client to be deleted does not exist in the identification information of the client to be recorded and broadcast, the recording and broadcasting system can return a second error response signaling to the conference control software, wherein the second error response signaling is used for indicating that the recording and broadcasting information corresponding to the client to be deleted does not exist. The recording and broadcasting system can also record the identification information of the client to be deleted and the like into an abnormal log so as to analyze the recording and broadcasting system in the subsequent process.

Step 210, finding whether an authorization code bound with the client to be deleted exists.

And step 211, when the authorization code exists, unbinding the to-be-deleted client and the authorization code bound with the to-be-deleted client.

Since the client to be deleted may have bound the authorization code or may not have bound the authorization code, the recording and playing system may also find whether the authorization code bound to the client to be deleted exists after deleting the identification information of the client to be deleted and the recording and playing parameter corresponding to the client to be deleted from the recording and playing information.

If the authorization code bound with the client to be deleted exists, the authorization of the client to be deleted is not allowed to be authorized any more subsequently after the identification information of the client to be deleted is deleted, and the client to be deleted does not need to continuously bind the authorization code, so that the recording and broadcasting system unbinds the authorization code bound with the client to be deleted and recovers the authorization code bound with the client to be deleted, and the authorization code can be bound with other clients subsequently. And if the authorization code bound with the client to be deleted does not exist, the recording and playing system does not need to process the authorization code.

In the embodiment of the invention, after the audio and video stream of the client is recorded, the recorded audio and video stream can be edited. And deleting the stored recorded and broadcast information so as to control which clients are not authorized any more and timely recover the authorization codes which do not need to be bound continuously.

EXAMPLE III

Referring to fig. 3, a flowchart of steps of a recording and playing method according to a third embodiment of the present invention is shown. The recording and broadcasting method of the embodiment of the invention can be applied to the client.

step 301, after the video conference starts, sending an authorization request signaling to the recording and broadcasting system, where the authorization request signaling carries identification information of a current client.

After the video conference starts, the current client can generate an authorization request signaling carrying identification information of the current client, and send the authorization request signaling to the recording and broadcasting system, so that the recording and broadcasting system is requested to authorize the current client, and audio and video streams of the current client are allowed to be recorded.

Step 302, receiving an authorization code bound for the current client, which is returned by the recording and playing system after determining that the current client is the client to be recorded and played, for the authorization request signaling.

And after receiving the authorization request signaling, the recording and broadcasting system determines whether the current client is the client to be recorded and broadcasted according to the authorization request signaling. And if the current client is determined to be the client to be recorded and broadcasted, the recording and broadcasting system binds an authorization code for the current client and returns the authorization code to the current client.

And 303, acquiring audio and video stream, and sending the audio and video stream and the authorization code to the recording and playing system, so that the recording and playing system records the audio and video stream according to the recording and playing parameter corresponding to the current client after successfully checking the authorization code.

If the current client receives the authorization code returned by the recording and broadcasting system, the current client can know that the authorization of the recording and broadcasting system is obtained, and can send the audio and video stream of the current client to the recording and broadcasting system for recording.

The client has a microphone and a camera. Wherein the microphone is used for collecting audio streams and the camera is used for collecting video streams. The current client acquires audio and video streams, wherein the audio and video streams comprise audio streams and video streams. The current client packs audio and video stream into a data packet, and in the implementation, the current client can pack the audio stream into an audio data packet and pack the video stream into a video data packet. The current client adds the received authorization code to a data packet obtained by packaging the audio and video stream, and then wants the recording and playing system to send the data packet, thereby realizing the purpose of sending the audio and video stream and the authorization code to the recording and playing system.

If the current client does not receive the authorization code returned by the recording and broadcasting system, the current client can know that the authorization of the recording and broadcasting system is not obtained, and cannot send the audio and video stream of the current client to the recording and broadcasting system for recording. So the current client does not do subsequent processing.

In the process of recording the audio and video stream of the current client, the camera corresponding to the current client can be adjusted according to actual requirements, so that a certain person or a certain area can be focused, and the quality of recorded content is improved.

When the camera needs to be adjusted, a manager can set adjustment parameters in a user interface provided by the conference control software. And after setting, the conference control software generates a camera adjusting signaling, the camera adjusting signaling carries the set adjusting parameters, and the conference control software sends the camera adjusting signaling to the current client. After receiving the camera adjustment signaling, the current client analyzes the camera adjustment signaling to obtain the adjustment parameters carried in the camera adjustment signaling. And the current client adjusts the corresponding camera according to the adjustment parameter.

The adjustment parameter may include parameters such as an angle of the camera, a focusing manner, and a zoom size, which is not limited in this embodiment of the present invention.

The recording and broadcasting method is introduced from the recording and broadcasting system side and the client side, respectively, and the recording and broadcasting method is explained in the following as a whole.

EXAMPLE five

In the embodiment of the invention, a recording and broadcasting process in a video conference of a video network is taken as an example for introduction. In the video network, the video network server uniformly schedules services in the video network, various devices need to be registered in the video network server when accessing the video network, and the video network server distributes information such as a Media Access Control (MAC) address, a terminal number and the like for the registered devices after registration. In the video network, devices communicate through information such as the video network MAC address, terminal number, etc.

Referring to fig. 5, a device interaction diagram of a recording and playing process according to a fifth embodiment of the present invention is shown. It should be noted that some devices are not shown in fig. 5, and will be described in detail below.

As shown in fig. 5, the recording and playing process may include:

step 1, inputting identification information of a client to be recorded and broadcasted.

Before the video conference begins, a record button is clicked through Pamir (Pamir in fig. 5 refers to conference control software, and may be 16-bit or 64-bit), signaling for filling identification information of a client to be recorded and broadcasted (the client to be recorded and broadcasted may be a palmtop or a webpage end, and the palmtop refers to an APP of a mobile terminal) is initiated, and the identification information of the client to be recorded and broadcasted is filled. Pamir packs the identification information of the client to be recorded and broadcast based on the video networking protocol, adds the identification information of the recording and broadcast system in the data packet, sends the data packet to a video networking server (not shown in fig. 5), and forwards the data packet to the recording and broadcast system by the video networking server according to the identification information of the recording and broadcast system. And the recording and broadcasting system analyzes the received data packet and stores the identification information of the client to be recorded and broadcasted into a database. Wherein the identification information may include at least one of: a MAC address of a video network, an IP (Internet Protocol) address, a terminal number, and the like.

And step 2, setting recording and broadcasting parameters.

And initiating a signaling of the newly added recorded broadcast parameters through Pamir, and filling the recorded broadcast parameters (the recorded broadcast parameters are associated with the client to be recorded and broadcast). Pamir packs recording and broadcasting parameters based on a video networking protocol, adds identification information of a recording and broadcasting system in a data packet, sends the data packet to a video networking server, and forwards the data packet to the recording and broadcasting system by the video networking server according to the identification information of the recording and broadcasting system. And the recording and broadcasting system analyzes the received data packet and stores the recording and broadcasting parameters and the identification information of the client to be recorded and broadcasted into a database in a correlation manner so as to authorize the recording and broadcasting subsequently. Wherein, the recording and broadcasting parameters may include at least one of the following: recording time, video size, compression ratio, etc.

It should be noted that, regarding step 1 and step 2, Pamir may fill in the identification information and the recording and broadcasting parameters of the client to be recorded and broadcast at one time, and perform the packaging and sending together, and the packaging and sending process is basically the same as the above-mentioned packaging and sending process.

And step 3, obtaining authorization.

After the video conference starts, the palmtop or web page terminal (the palmtop or web page terminal in fig. 5 refers to the current client) generates an authorization request signaling based on the internet protocol, where the authorization request signaling may include identification information of the palmtop or web page terminal (that is, the current client), and may also include identification information of the recording and playing system. Since the palmtop and the web page belong to the client in the internet, if the client is to access the internet of view, the protocol conversion is performed through the protocol conversion gateway (not shown in fig. 5). Therefore, the palm top or the webpage end 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 video networking protocol. In implementation, the coordination gateway may add a video networking protocol header to the authorization request signaling based on the internet protocol, to obtain the authorization request signaling based on the video networking protocol. The video network protocol header may include information such as a source MAC address (video network MAC address of the protocol gateway) and a destination MAC address (video network MAC address of the recording and broadcasting system). The protocol conversion gateway sends the authorization request signaling based on the video networking protocol to the video networking server, and the video networking server forwards the authorization request signaling based on the video networking protocol to the recording and broadcasting system according to the identification information of the recording and broadcasting system.

And 4, returning the authorization code.

And (3) the recording and broadcasting system analyzes the authorization request signaling after receiving the authorization request signaling to obtain the identification information of the palm communication or the webpage end, and compares and verifies the identification information of the palm communication or the webpage end with the identification information of the client to be recorded and broadcast, which is input in the step (1). If the two codes are the same, the recording and broadcasting system is a palm communication or webpage end binding authorization code. The recording and broadcasting system packages an authorization code based on a video networking protocol, adds identification information of the palm communication or the webpage end and identification information of the protocol conversion gateway, returns the authorization code to the video networking server, returns the authorization code to the corresponding protocol conversion gateway according to the identification information of the protocol conversion gateway, converts the video networking protocol into an internet protocol by the protocol conversion gateway, and returns the authorization code to the palm communication or the webpage end by the protocol conversion gateway. If not, the recording and broadcasting system returns a null authorization code or does not return information according to the flow, records the relevant information of the authorization request signaling, and stores the information into an abnormal log of the intelligent recording and broadcasting service system.

And 5, audio and video stream transmission.

After the palm channel or the webpage end receives the authorization code, the audio and video stream and the authorization code are packaged based on the internet protocol, and the identification information of the palm channel or the webpage end and the identification information of the recording and broadcasting system can also be packaged. The palm top or the webpage end sends the data packet based on the internet protocol encapsulation to the protocol conversion gateway, and the protocol conversion gateway converts the data packet based on the internet protocol encapsulation into the data packet based on the video networking protocol encapsulation. In implementation, the coordination gateway may add a packet header of the video networking protocol to the data packet encapsulated based on the internet protocol, so as to obtain the data packet encapsulated based on the video networking protocol. The video network protocol header may include information such as a source MAC address (video network MAC address of the protocol gateway) and a destination MAC address (video network MAC address of the recording and broadcasting system). And the protocol conversion gateway sends the data packet encapsulated based on the video networking protocol to the video networking server, and then the video networking server sends the data packet encapsulated based on the video networking protocol to the recording and broadcasting system according to the identification information of the recording and broadcasting system.

And the recording and broadcasting system analyzes the data packet after receiving the data packet to obtain audio and video streams, an authorization code, identification information of the palm channel or the webpage end and the like, and acquires the authorization code bound to the palm channel or the webpage end in the prior art according to the identification information of the palm channel or the webpage end. If the authorization code bound for the palm top or the webpage end exists, the received authorization code is compared with the authorization code bound for the palm top or the webpage end, if the two authorization codes are the same, the authorization code is verified successfully, and otherwise, the authorization code is verified unsuccessfully. And if the authorization code which is bound by the palm-top or the webpage end does not exist, the verification of the authorization code fails. And (3) after the authorization code is successfully verified, the recording and broadcasting system cuts and stores the audio and video stream in fragments by combining the recording and broadcasting parameters set for the palm communication or the webpage end in the step 1.

And 6, sending a recorded broadcast editing signaling.

When a video conference is carried out, a recording and broadcasting editing button is clicked through Pamir, Pamir is triggered to generate a recording and broadcasting editing signaling based on a video networking protocol, and identification information of a client to be edited, an editing type and identification information of a recording and broadcasting system are added in the recording and broadcasting editing signaling. Pamir sends the recorded broadcast editing signaling based on the video networking protocol to a video networking server, and the video networking server forwards the recorded broadcast editing signaling based on the video networking protocol to the recorded broadcast system according to the identification information of the recorded broadcast system. And the recorded broadcast system analyzes the recorded broadcast editing signaling after receiving the recorded broadcast editing signaling, and edits the audio and video stream corresponding to the client to be edited according to the editing type. For example, if the editing type is calling, the recording and playing system encapsulates the audio and video stream corresponding to the client to be edited based on the video networking protocol to obtain a data packet, returns the data packet to the video networking server, and returns the data packet to Pamir by the video networking server, thereby calling the recorded audio and video stream.

And 7, sending a camera adjusting signaling.

When a video conference is carried out, adjustment parameters of a camera of the palm communication or the webpage end are set through Pamir, Pamir is triggered to generate a camera adjustment signaling based on a video networking protocol, and identification information of the palm communication or the webpage end, the adjustment parameters and identification information of the coordination gateway are added into the camera adjustment signaling. And Pamir sends the camera adjustment signaling based on the video networking protocol to a video networking server, and the video networking server sends the camera adjustment signaling based on the video networking protocol to the protocol conversion gateway according to the identification information of the protocol conversion gateway. The cooperation gateway converts the camera adjustment signaling based on the video networking protocol into the camera adjustment signaling based on the internet protocol, and sends the camera adjustment signaling to the palm top or the webpage end according to the identification information of the palm top or the webpage end. The palm communication or the webpage end analyzes the camera adjustment signaling to obtain an adjustment parameter, and adjusts the camera corresponding to the palm communication or the webpage end according to the adjustment parameter, such as adjusting the angle, the focusing mode, the zoom size and the like of the camera.

In the embodiment of the invention, the requesting client can be authorized according to the preset identification information of the client to be recorded and broadcasted, and the audio and video stream of the authorized client can be recorded according to the recording and broadcasting parameters. Meanwhile, the moving and focusing of the camera can be controlled in the recording process to improve the video recording quality.
