In the foregoing operating environment, the present application provides a multimedia streaming service method as shown in fig. 2, fig. 2 is a flowchart of a multimedia streaming service method according to an embodiment of the present application, and as shown in fig. 2, the method includes the following method steps:

step S202, the multimedia stream service system receives a request message sent by at least one terminal through an http DNS interface of at least one multimedia service device;

step S204, responding to the request message, the multimedia streaming service system allocates a corresponding IP address to the at least one terminal.

Optionally, the terminal may be a computer terminal, a mobile terminal (mobile phone, PAD), and the like, and is classified by a user principal, and the terminal may include at least one of the following: a media stream transmitting end (e.g., a main end), a media stream receiving end (e.g., a play end).

The multimedia service device can be a multimedia service terminal, such as a multimedia server and a media resource server; the request message may be a request for a media asset service, and for example, the terminal is a media stream transmitting end, the request message may be transmitted when the media stream transmitting end operates and starts to log in a media asset service application; taking the terminal as a media stream receiving end as an example, the request message may be sent when the media stream receiving end starts running the media asset service application.

In an optional embodiment, taking the media stream sending end as an anchor end as an example, when an anchor worker logs in the anchor end, that is, when the anchor end runs and starts to log in the media asset service application, the request message is sent to request to access the http dns interface, instead of sending the request message when streaming is needed. Taking the above media stream receiving end as the playing end as an example, when the audience enters the playing end to watch the multimedia data, that is, when the playing end starts running the media asset service application, no matter the audience is in the login state or the guest state, the request message is sent to request to access the http dns interface, but the request message is sent when the streaming is not needed.

Specifically, the http dns interface is an interface of a content delivery network CDN (e.g., a commercial CDN), and by locally integrating the http dns interface in the multimedia service device, the http dns interface can be integrated more efficiently and more simply at both the media stream sending end and the media stream receiving end, and can play a role of http dns service.

In a live broadcast scene, the multimedia service device can provide an access interface for the terminal through the locally integrated http dns interface, and access, update and acquisition of http dns of the service end are realized in live video broadcast, so that development cost and maintenance cost of the client can be reduced, and overhead on the client is reduced.

As an optional embodiment, the request information carries IP address information of the terminal, and in this embodiment, taking the IP address carried in the media asset service request as a Clientip:110.11.11.11 as an example, after receiving the request information, the multimedia streaming service system may provide a domain name resolution service to the terminal according to the request information and the IP address information of the terminal carried in the request information, and allocate a corresponding IP address to the terminal.

In the above-described alternative embodiment, the domain name resolution service may be provided by at least one http dns service device (e.g., a content delivery network CDN server).

Therefore, the purposes of reducing the development cost and the maintenance cost of the client are achieved, the client overhead is reduced, the technical effect of providing more convenient and efficient http dns service for a user is achieved, and the technical problem that the development cost and the maintenance cost of the client are high due to the fact that the http dns interface is integrally arranged on the client in the existing multimedia stream service method is solved.

In an optional embodiment, after the multimedia streaming service system allocates the corresponding IP address to the at least one terminal, the method further includes:

step S302, the multimedia service apparatus refreshes the http dns interface according to a set period to obtain an updated IP address.

In an alternative embodiment, the set period may range from 0.5 to 2 minutes. For example, if the preset update frequency may be 1 minute each time, the multimedia service device automatically refreshes the http dns interface every 1 minute interval to obtain updated IP address information.

Based on the above optional embodiment, when the media stream sending end needs to push the stream, or when the media stream receiving end needs to pull the stream, the multimedia service device issues the updated IP address information to the terminal, so as to facilitate the media stream transmission between the terminal and the CDN source station.

the multimedia stream service system receives, through at least one edge node, a multimedia stream pushed by a first terminal of the at least one terminal through the updated IP address.

In an optional embodiment, when the media stream sending end needs to push the stream, the multimedia service device issues updated IP address information to the media stream sending end, and then the media stream sending end can push the multimedia stream to at least one edge node through the updated IP address based on the updated IP address information, so as to implement the stream pushing from the media stream sending end to the CDN source station.

Optionally, the edge node may be a CDN edge node, for example, a live CDN edge node, and the setting of at least one edge node may facilitate the terminal to access the CDN source station nearby, thereby shortening a time delay for the terminal to access the media stream, and improving efficiency of media stream transmission between the terminal and the CDN source station.

the multimedia stream service system provides a multimedia stream to a second terminal of the at least one terminal through at least one edge node, so that the second terminal pulls the multimedia stream from the at least one edge node through the updated IP address.

Specifically, the second terminal is a media stream receiving end (e.g., a playing end, a viewer end), and the media stream receiving end is configured to receive multimedia data provided by the multimedia streaming service system.

In another optional embodiment, when the media stream receiving end needs to pull the stream, the multimedia service apparatus issues updated IP address information to the media stream receiving end, and the media stream receiving end may pull the multimedia stream from the at least one edge node through the updated IP address based on the updated IP address information. The media stream receiving end can pull the current live multimedia stream from the CDN source station due to the connection between the edge node and the CDN source station.
