Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart of a signaling control method based on a multimedia interactive system according to a preferred embodiment of the present invention, which includes the steps of:
s100, presetting basic operation contents of the multimedia interactive service, including an operation object and an operation direction, and combining the basic operation contents to form different basic operations.
The method specifically comprises the following steps:
s110, setting the operation object as video or audio, and setting the operation direction as uploading or downloading;
s120, combining the operation object and the operation direction to form different basic operations: uploading the video; downloading the video; uploading audio; and (5) audio downloading.
Specifically, because multimedia signaling is used to control the transceiving of audio and video, and the operation of all multimedia interactive services aims at this, the signaling control design method of the existing multimedia interactive system (such as a multimedia command scheduling system, a video conference system, etc.) can be improved according to the signaling nature.
For the sake of understanding, the multimedia interactive service is abstracted into a basic operation according to its essence, and the basic operation is called op (operation), each op contains a target and a direction, called their target and direct respectively:
target is represented by a character string, and only possibly being "video" or "audio", representing whether the operation object at this time is video or audio;
the direct is represented by a character string, and only can be up or down, which indicates whether the current operation object is uploaded or downloaded, and correspondingly, the operation object is sent and received.
The basic operation content can describe the basic operation of the media in a multimedia interactive service.
The method is different from the method for formulating the signaling based on the call in the existing multimedia interaction system, abstracting the functional operation of the multimedia interaction service, formulating the signaling based on the operation content, abstracting the operation of the multimedia interaction service into an operation object and an operation direction, and then independently describing the operation object and the operation direction, so that the operation of the multimedia interaction service can be decomposed into various basic operations, and then the basic operations are combined to achieve the purpose of describing the operation of any multimedia interaction service.
Compared with the method for formulating the multimedia interaction signaling in the prior art, the method abstracts the operation of the multimedia interaction service into the method for formulating the signaling based on the operation object and the operation direction, simplifies the type and the number of the signaling in the multimedia interaction system, and ensures that the signaling control has great flexibility and expansibility, thereby simplifying and efficiently formulating, modifying and maintaining the signaling in the multimedia interaction system, and greatly reducing the development workload of the multimedia interaction system.
S200, judging the basic operation contained in each multimedia interactive service to form a basic operation combination.
The method specifically comprises the following steps:
s210, judging which basic operations are contained in each multimedia interactive service;
and S220, forming a basic operation combination by all basic operations contained in the multimedia interactive service.
As can be seen from the above, in the specific implementation process, it is first determined which basic operations are included in each multimedia interactive service, that is, which operations include video uploading, video downloading, audio uploading, and audio downloading, each multimedia interactive service operation includes a group of ops, and the ops are managed first, that is, a basic operation combination, where at least one op (an op is one of video uploading, video downloading, audio uploading, and audio downloading), one service operation corresponds to one ops, and one ops includes n ops, and further includes user names of sources and destinations of multimedia interactive services, and taking an a client as a source client and a B client as a destination client as an example, a complete ops structure is as follows:
message ops
{
src_name="A";
dst_name="B";
message op[0]
{
target="video"
direct="up"
}
message op[1]
{
target="video"
direct="down"
}
message op[2]
{
target="audio"
direct="up"
}
message op[3]
{
target="audio"
direct="down"
}
}
in another aspect, to process a certain multimedia interactive service, the multimedia interactive service is first decomposed according to the basic operations, and the basic operations included in the multimedia interactive service are analyzed, so that a basic operation combination is formed according to the basic operations as operations related to the multimedia interactive service, and the complexity of signaling control can be simplified in an abstract manner.
It can be seen from the above that, the multimedia interaction service function is simplified by an abstract manner, the multimedia interaction signaling is controlled based on operation including an operation object and an operation direction, which is obviously different from the idea of controlling the multimedia interaction signaling based on a call in the prior art, the multimedia interaction service operation is decomposed into a plurality of basic media operation granularities according to media by using an operation-based model, and different media interaction services can meet different service operation requirements only by combining the granularities, so that the description is more direct, concise and flexible, the number and types of signaling messages can be greatly reduced, and the signaling control has great flexibility and expansibility.
S300, the basic operation combination, the source and the target of the multimedia interactive service are taken as the signaling control information of the multimedia interactive service, and the interaction of the multimedia interactive service is realized with other terminals through a server.
The method specifically comprises the following steps:
s310, the basic operation combination, the source and the target of the multimedia interactive service are taken as signaling control information of the multimedia interactive service and sent to other terminals through a server;
s320, receiving signaling control information of other terminals sent by the server;
s330, the interaction of the multimedia interaction service is realized between the terminals through the server.
The control of the multimedia interactive service signaling is realized in the manner described above, and other processes can refer to the prior art and are not described herein again.
The following describes an implementation process in a specific embodiment, for example, when a user a and a user B want to implement a video call, a multimedia operation includes that the user a and the user B view videos mutually, and the user a and the user B talk back to each other through voice, please refer to fig. 2, which includes that the user a and the user B upload/download videos mutually, and the user a and the user B upload/download audio mutually, the schematic diagram shown in fig. 2 can be decomposed into four basic operations, and the following takes the operation of the user a client as an example:
1. the user a uploads (i.e., sends) the video to the user B, and then the user B views the user a video, and then the corresponding user B client downloads (i.e., receives) the user a video, and then the client a operates correspondingly as:
please refer to FIG. 2(a)
message op[0]
{
target="video"
direct="up"
}
2. Similarly, the user a checks the video of the user B, and correspondingly, the user B uploads the video to the user a, and the operation of the client of the user a is as follows:
please refer to FIG. 2(b)
message op[1]
{
target="video"
direct="down"
}
3. Similarly, the user a uploads the audio to the user B, and the user B listens to the audio of the user a, then the operation of the user a client is as follows:
please refer to FIG. 2(c)
message op[2]
{
target="audio"
direct="up"
}
4. Similarly, the user a listens to the audio of the user B, and the user B uploads the audio to the user a, then the operation of the user a client is as follows:
please refer to FIG. 2(d)
message op[3]
{
target="audio"
direct="down"
}
As can be seen from the above, any client operation of any multimedia interactive service can be combined by the above four basic operations. Such as:
video calling: by combining the above (1, 2,3, 4)
Voice call (i.e., voice call): is composed of the above (3, 4)
And (4) viewing the video: composed of (2)
Pushing a video: composed of (1)
And voice monitoring: composed of (4)
Audio and video monitoring: from the above (2, 4)
It can be extended that all the above multimedia interactive service operations are performed, so that only one ops message needs to be defined when defining the signaling message, the message processing needs to be realized only once, the processing end of the message server is not needed to be modified, and the signaling message sending client only needs to flexibly modify the structure.
From the above, it can be seen that if the existing basic service functions of a multimedia system are: video calling, voice calling, and the new requirements are put forward by the current customers, and the new functions are needed: monitoring voice, simultaneously monitoring voice video, and pushing the video to a user for watching, then:
according to the traditional signaling design, four signaling needs to be added according to the four functions, the client and the server are modified respectively to meet the requirements, and the four functions are tested respectively after modification;
by using the technical scheme of the invention, the server does not need to be modified, and only when the client sends the messages OPs, the modification of the combined OP can meet the requirements, because the server does not distinguish the specific OP in the processing, namely the newly added function does not need to be tested again for the server, and the increase and modification of any multimedia interactive service operation function in the future can be met after one-time testing.
In summary, for the multimedia interactive service, the description method of the present patent application is the most different from the conventional description method of the prior art in that the conventional is based on the call model, and the description method of the present patent application is based on the operation model. The method abstracts the multimedia interaction service model, decomposes the multimedia interaction service operation into a plurality of basic media operation granularities according to media by taking the operation as a basic model, and different multimedia interaction services can meet different service operation requirements only by combining the granularities.
