Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a method for accessing a network camera in a recording and broadcasting system, which can be realized by a recording and broadcasting host and the network camera in the recording and broadcasting system together. The network camera is used for shooting videos and transmitting the shot videos to the recording and broadcasting host, and the recording and broadcasting host is used for storing or guiding the received videos. The recording and broadcasting system can be applied to various application scenes such as classroom teaching, court trial, operation teaching and the like. Taking the application of the recording and broadcasting system in classroom teaching as an example, as shown in fig. 1, the recording and broadcasting system may include a recording and broadcasting host, a teacher-type webcam, and a student-type webcam. The teacher-type network camera can support two output channels, one output channel corresponds to a view finding type which is a panoramic type and is used for outputting a teacher panoramic video, and one output channel corresponds to a view finding type which is a close-range type and is used for outputting a teacher close-range video; the object type of a shooting object of the student type network camera is a student type and is used for shooting students, the student type network camera supports two output channels, the view finding type corresponding to one output channel is a panorama and is used for outputting a student panorama video, and the view finding type corresponding to one output channel is a close shot and is used for outputting a student close shot video.
As shown in fig. 2, the method comprises the steps of:
The user terminal may be a computer, a mobile terminal or other electronic devices.
In implementation, when a user needs to record a video through the recording and broadcasting system, the user may input an access instruction of the network camera on the user terminal, the user terminal may send an access request to the recording and broadcasting host after receiving the access instruction, and the recording and broadcasting host may receive the access request sent by the user terminal and then send a parameter acquisition request to the network camera.
Optionally, the access request may carry an IP (Internet Protocol) address of the network camera, the recording and broadcasting host may first determine whether the IP address is repeated, and if the IP address is not repeated, step 201 is executed, where the specific processing procedure is as follows: and the recording and broadcasting host judges whether the IP address of the network camera exists in a prestored address list or not. If the IP address of the network camera exists in the pre-stored address list, the recording and broadcasting host sends first error prompt information to the user terminal; and if the IP address of the network camera does not exist in the pre-stored address list, the recording and broadcasting host executes the step of sending a parameter acquisition request to the network camera.
In implementation, after receiving the access request, the recording and broadcasting host may analyze the access request to obtain the IP address of the network camera carried by the access request. The recording and broadcasting host can also store an address list, and the IP address of the network camera which the recording and broadcasting host has access to is stored in the address list.
The recording and broadcasting host can judge whether the IP address of the network camera exists in the address list or not. If the IP address of the network camera exists in the pre-stored address list, it is indicated that the network camera corresponding to the IP address has been accessed to the recording and broadcasting host, the recording and broadcasting host will send first error prompt information to the user terminal, the first error prompt information is used for prompting that the network camera corresponding to the IP address has been accessed to the recording and broadcasting host, and the user needs to reset the IP address of the network camera. If the IP address of the network camera does not exist in the pre-stored address list, which indicates that the network camera corresponding to the IP address does not access the recording and broadcasting host, the recording and broadcasting host may execute the step of sending a parameter acquisition request to the network camera corresponding to the IP address.
Optionally, the access request may also carry a user name and a password, and accordingly, a specific processing procedure for the recording and broadcasting host to send the parameter acquisition request to the network camera may be as follows: and the recording and broadcasting host sends a parameter acquisition request carrying a user name and a password to the network camera so that the network camera performs identity authentication according to the user name and the password, and sends camera parameters to the recording and broadcasting host when the authentication is passed.
In implementation, a user can input a user name and a password in a user terminal and then input an access instruction, and the user terminal can acquire the user name and the password and then send an access request carrying the user name and the password to a recording and broadcasting host. After receiving the access request, the recording and broadcasting host can analyze the access request, acquire a user name and a password carried by the access request, further generate a parameter acquisition request carrying the user name and the password according to the user name and the password, and send the parameter acquisition request to the network camera, so that the network camera can perform identity authentication according to the user name and the password, and return corresponding information to the recording and broadcasting host according to an authentication result. In the embodiment of the application, the network camera sends the camera parameters to the recording and broadcasting host only when the network camera passes the verification, so that the safety of the network camera accessing to the recording and broadcasting host can be improved.
In step 203, the network camera acquires the pre-stored camera parameters.
The camera parameters may include an object type of a shooting object of the network camera, for example, when the network camera shoots a classroom teaching, the object type is a teacher type or a student type, the teacher type indicates that the shooting object of the network camera is a teacher, and the student type indicates that the shooting object of the network camera is a student.
In implementation, the network camera may store camera parameters in advance, the camera parameters may be configured in advance by a technician, and the network camera may acquire the locally stored camera parameters after receiving the parameter acquisition request.
Optionally, the camera parameter further includes the number of output channels supported by the network camera.
The output channel of the network camera is used for outputting the video shot by the network camera, the network camera can have a plurality of output channels, and the corresponding view type of each output channel can be the same or different. For example, the network camera has two output channels, wherein the view type corresponding to one output channel is a close-range view type, the video output by the output channel is a close-range view video, the view type corresponding to the other output channel is a panoramic view type, and the video output by the output channel is a panoramic video.
And step 204, the network camera sends the camera parameters to the recording and broadcasting host.
In implementation, after the network camera acquires the camera parameters, the network camera may send the camera parameters to the recording and broadcasting host, so that the recording and broadcasting host accesses the output channel of the network camera to the local input channel, and sets the channel type of the input channel as the channel type corresponding to the object type. Therefore, the self-adaptive access of the network camera can be realized, the channel type in the recording and broadcasting host does not need to be manually set by a user, the user operation is simplified, and the efficiency of accessing the network camera to the recording and broadcasting host is improved.
Optionally, the parameter obtaining request may also carry a user name and a password. Correspondingly, the network camera may send the camera parameters again when the authentication is passed according to the user name and the password, and the specific processing procedure may be as follows: and the network camera carries out identity authentication according to the user name and the password. If the verification is passed, the network camera sends camera parameters to the recording and broadcasting host; and if the verification is not passed, the network camera sends third error prompt information to the user terminal.
In implementation, a user name and a password may be stored in advance in the network camera, and when the network camera receives a parameter acquisition request, the network camera may analyze the parameter acquisition request to acquire the user name and the password carried by the parameter acquisition request, and may further determine whether the received user name and password are consistent with the locally stored user name and password. If the received user name and the received password are consistent with the locally stored user name and the locally stored password, judging that the authentication is passed; if the received username and password are not consistent with the stored username and password, then the authentication is determined to be failed.
If the network camera judges that the verification is passed, the prestored camera parameters can be obtained, and the camera parameters are sent to the recording and broadcasting host; and if the network camera judges that the verification is not passed, the network camera sends third error prompt information to the recording and broadcasting host, wherein the third error prompt information is used for indicating that the user name and the password are incorrect. Correspondingly, after receiving the third error prompt message, the recording and broadcasting host can send the third error prompt message to the user terminal, and after receiving the error prompt message, the user terminal can display the third error prompt message to prompt that the user name and the password are wrong. Alternatively, the network camera may directly send the third error prompt message to the user terminal.
And step 205, the recording and broadcasting host receives the camera parameters sent by the network camera.
Wherein the camera parameter includes an object type of a photographic object of the network camera.
And step 206, the recording and broadcasting host accesses the output channel of the network camera into the local input channel and sets the channel type of the input channel as the channel type corresponding to the object type.
In implementation, the recording and broadcasting host may store the identifier of each output channel in advance, after the recording and broadcasting host receives the camera parameters sent by the network camera, the recording and broadcasting host may send a channel access request to the network camera, where the channel access request carries the identifier of the output channel, and when the network camera receives the channel access request, the network camera may reply a response message through the corresponding output channel according to the identifier of the output channel. And the recording and broadcasting host accesses the responded output channel to a local input channel and sets the channel type of the input channel as a channel corresponding to the object type. For example, assuming that the object type of the shooting object of the network camera is a teacher type, the recording and broadcasting host accesses the output channel of the network camera to the local input channel, and sets the channel type of the input channel as the teacher channel type.
Optionally, when the camera parameter further includes the number of output channels supported by the network camera, the processing procedure of step 106 may be: if the number of the output channels is multiple, the recording and broadcasting host accesses the channel to a local input channel aiming at each output channel, then determines a target view type corresponding to the output channel according to a preset corresponding relation between the output channel and the view type, and sets the channel type of the input channel accessed by the output channel as the channel type corresponding to the object type and the target view type.
In implementation, for each output channel, the recording and broadcasting host sends a channel access request of the output channel to the network camera, where the channel access request carries an output channel identifier of the output channel, and when the network camera receives the channel access request, the network camera may send a response through a channel corresponding to the output channel identifier, and the recording and broadcasting host accesses the output channel in response to a local input channel.
The recording and playing host stores the corresponding relationship between the output channel of the network camera and the view type in advance, for example, the network camera supports two channels, the view type corresponding to the first output channel is a close-range type, which indicates that the first output channel outputs a close-range video, the view type corresponding to the second output channel is a panoramic type, which indicates that the second output channel outputs a panoramic video, and then the recording and playing host stores the information of the close-range type corresponding to the first output channel and the panoramic type corresponding to the second output channel in advance. The recording and broadcasting host determines the target view type corresponding to each preset output channel according to the corresponding relationship between the output channel and the view type, for example, the channel is a first channel, and the preset corresponding relationship includes a close-range type corresponding to the first channel, so that the recording and broadcasting host determines that the target view type of the channel is the close-range type. Then, the recording and broadcasting host sets the channel type of the input channel accessed by the output channel as the channel type corresponding to the object type and the target view type, for example, if the object type is the student type and the target view type is the close-range type, the recording and broadcasting host sets the channel type of the input channel accessed by the output channel as the student close-range type.
Optionally, if the number of the output channels is one, the recording and broadcasting host sends a second error prompt message to the user terminal.
Optionally, if the object type does not belong to the preset object type, the recording and playing host sends a fourth error prompt message to the user terminal.
The preset object type is determined according to the object type of the shot object of the network camera in the recording and broadcasting system, for example, the recording and broadcasting system is applied to classroom teaching, the network camera mainly shoots students and teachers, the object type of the shot object of the network camera is divided into two types, one type is a teacher type and the other type is a student type, then the preset object type can comprise a teacher type and a student type, if the object type is a common type, the recording and broadcasting host judges that the object type does not belong to the preset object type, and then fourth error prompt information is sent to the user terminal.
Therefore, the self-adaptive access of the network camera can be realized, the user does not need to manually set the channel type in the recording and broadcasting host, the user operation is simplified, and the efficiency of accessing the network camera to the recording and broadcasting host is improved.
Taking the recording and broadcasting system shown in fig. 1 as an example, the present invention further provides a specific embodiment of a method for accessing a network camera in the recording and broadcasting system, and the method is applied to a recording and broadcasting host.
