Description

Method and device for releasing multimedia resources

Technical field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for distributing multimedia resources.

Background technique

The improvement of network bandwidth and the development of 4G (Fourth Generation) wireless communication technology have made it possible to carry out media content-based service services on the Internet.

detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

It is to be understood that the terms "first", "second" and the like in the specification and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a particular order or order.

In this embodiment, a method for distributing a multimedia resource is provided. FIG. 1 is a flowchart of a method for publishing a multimedia resource according to an embodiment of the present invention. As shown in FIG. 1 , the process includes the following steps:

Step S102: The media publishing server receives a request message for requesting to issue a multimedia resource.

In this embodiment, the multimedia resource may be a video resource, an audio resource, or a picture or other multimedia resource. When there is a multimedia resource to be released, the video captured by the user or the live broadcast video transmitted from the remote end needs to be uploaded. The request message for publishing the multimedia resource is sent to the media publishing server, and the multimedia publishing server receives the request message and performs subsequent processing. Optionally, the multimedia publishing server may be a website of a video website, a live broadcast platform, a sharing platform, or a software server.

Step S104: The media publishing server acquires different versions of the multimedia resources from the content providing server, where the code rates between different versions of the multimedia resources are different.

In this embodiment, the multimedia resource includes one or more versions, and each version may have different definitions due to different code rates, such as ultra high definition, high definition, normal, etc., each version occupies the capacity of the multimedia resource, correspondingly Each multimedia resource of the version occupies a corresponding capacity and bandwidth when the multimedia resource is saved or transmitted.

Step S106: The media publishing server deletes a partial version from different versions of the multimedia resource, and stores the remaining version of the multimedia resource.

Optionally, some versions of multimedia resources, such as Ultra HD versions, do not need to be published on the publishing server because of the multimedia itself, or the memory capacity and bandwidth, or the reason why the user uses too little. Different versions of the multimedia resource are deleted, the unneeded version is deleted, and the storage is to be released.

Step S108: The media publishing server selects one or more of the remaining versions of the multimedia resources for publishing.

After the multimedia resource is stored, when the multimedia publishing server receives the request for the transmission of the multimedia resource or the message downloaded from the server, one or more of the remaining versions of the multimedia resource to be released are stored.

In this embodiment, the media publishing server receives a request message for requesting to issue a multimedia resource, and the media publishing server acquires different versions of the multimedia resource from the content providing server, where a code rate between different versions of the multimedia resource is different; The publishing server deletes part of the version from the different versions of the multimedia resource and stores the remaining versions of the multimedia resource; the media publishing server selects one or more of the remaining versions of the multimedia resource for publishing. The invention solves the problem that the storage space and the bandwidth are too large when the multimedia resources are released in the related art, thereby achieving the effect of saving storage space and bandwidth under the service experience of the user.

The low-frequency three-speed, resource type information is carried in the request message when the resource request is issued, and is generated by the upper layer network, that is, the video frequency Video Frequency field, 1 indicates low frequency, 2 indicates intermediate frequency, and 3 indicates high frequency. The high frequency type multimedia resource may be a live ball game content, and the low frequency type multimedia resource may be an animation, and the predetermined publishing policy may be pre-set processing of deleting a partial version of one or more types of multimedia resources, such as deleting a high frequency. And partial versions of multimedia resources of low frequency type, but no processing of multimedia resources of intermediate frequency type.

S12. If it is determined that the partial version needs to be deleted, the media publishing server deletes the partial version from different versions of the multimedia resource.

Optionally, the media publishing server determines whether the partial version needs to be deleted according to the resource type of the multimedia resource and the predetermined publishing policy, and the media publishing server determines whether the target resource type of the target multimedia resource that needs to delete the target version indicated by the predetermined publishing policy includes multimedia. The resource type of the resource; if the resource type of the multimedia resource is included, it is determined that the partial version needs to be deleted. In the specific judging process, the resource type that needs to be deleted in the partial release policy is deleted, and the Video Frequency field of the multimedia resource is parsed. If the resource type corresponding to the predetermined publishing policy is deleted, the multimedia resource is deleted. Version processing.

Optionally, the media publishing server deleting the partial version from different versions of the multimedia resource includes: the media publishing server determining whether the different versions of the multimedia resource include the target version, and if the target version is included, deleting the target version from different versions of the multimedia resource. In the specific deletion process, the predetermined release policy also indicates which specific version of the multimedia resource is deleted, such as deleting the high frequency and intermediate frequency versions of the multimedia resource, then the high frequency and the intermediate frequency are the target versions, and only the low frequency version is retained, and all of the multimedia resources are When the version includes a version in which the predetermined policy indicates deletion, the target version is deleted, and when all versions of the multimedia resource do not have the target version, no processing is performed. Optionally, when there is only one version of the multimedia resource, and the version is the target version, the version of the multimedia resource is not deleted.

In an optional implementation in accordance with an embodiment of the present invention, the media publishing server deleting the partial version from the different versions of the multimedia resource includes the media publishing server deleting the version with the highest rate from the different versions of the multimedia resource.
