And (3) uid: and accessing the whole network unique identification of the user. key: keys agreed upon by the customer and CDN vendor. And the user uses the URL to initiate a request to a large-screen central authentication server, the central authentication server records and verifies the IP address, if the number of the IP addresses does not exceed N, the request is allowed, and if not, the access is denied.
As a possible implementation, further, the method further includes:
and the EPG content management system is used for carrying out approval, release, pause, off-shelf, deployment, management and control, distribution and limitation on the broadcasting of the appointed program content and the configuration of the EPG content by the terminal user on the media asset content. Thereby effectively managing the legality and correctness of the media asset content.
As a possible implementation manner, further, the EPG content management system includes:
the content approval module is used for carrying out approval confirmation on the content information before issuing and EPG collecting processing; the content service platform checks and confirms the approved content information integrated broadcast control platform, and the approved system can release and collect the EPG on the content information, thereby ensuring the correctness and the legality of the film information watched by the user.
The content distribution deployment module is used for deploying the specified content file to the CDN content storage node of the specified area according to the service requirement; the terminal equipment can acquire the content file from the nearest CDN storage node, so that the downloading speed of the terminal equipment for acquiring the content file is increased, and the access pressure of other CDN storage nodes is relieved. The deployment operation of the content files is carried out in a P2P mode, and data sharing can be carried out among CDN storage nodes; the system supports two modes of central node distribution and deployment and edge node distribution and deployment, and greatly facilitates the operability of content file deployment. The central node uploading distribution deployment comprises the following steps: the content file can be distributed and deployed from the central content management system, and the content file is controlled to be distributed and deployed to the CDN content storage node in the designated area; the transmission among CDN storage nodes adopts a P2P mode for transmission; the distribution and deployment mode of the system to the content files comprises the following steps: manual immediate distribution, designated area distribution, intelligent distribution, hierarchical distribution, and timed distribution. The edge node uploading distribution deployment comprises the following steps: because the system adopts a transmission mode of P2P, the system supports the distribution and deployment of content files from any one edge CDN storage node to other CDN storage nodes, thereby facilitating the uploading of the content files from different places by service providers; and managing and controlling the edge uploaded content files, distributing and deploying.
The content management and control module is used for controlling the availability of the content file and performing playing limitation on the terminal user to timely and effectively manage and control the content file; it can perform content publishing operations: the content publishing is mainly used for publishing the audited media asset information, diversity information and content files, and only the content in the publishing state can be watched by the terminal user. The content publishing operation can independently publish the media asset information, the diversity information and the content file, and can be published according to different requirements, so that the publishing operation of the content is flexibly controlled. Media information: basic information of a program movie; diversity information: information of each episode (period) of a program movie; content file: the entity file finally played by the terminal equipment; the system provides two modes of manual publishing and timing publishing for content publishing. The content pause/resume system can pause and resume the content which has been distributed, and after the content is paused, the end user cannot browse and select the content, but the end user who is playing can continue to watch the content. The operator of the paused content can carry out the recovery operation, and the terminal user can browse and play the recovered content normally; the system can perform individual pause or resume operations on the media asset information, diversity information and content files. The content shelf-off operation can also be carried out: the system allows the off-shelf operation of the released or suspended content, the end user of the off-shelf content cannot watch the off-shelf content, and the off-shelf content cannot be recovered. After the content is off shelf, the terminal watching the content will immediately interrupt the current playing, and the content files on each CDN storage node in the system will also be deleted synchronously. The system can perform independent shelf unloading operation on the media asset information, the diversity information and the content file.
And the content playing limiting module is used for controlling the playing permission of the content according to the terminal, the region, the content and the service provider. The restricted end user will not be able to play the designated content file but can browse the EPG information for that content.
The foregoing is directed to embodiments of the present invention, and equivalents, modifications, substitutions and variations such as will occur to those skilled in the art, which fall within the scope and spirit of the appended claims.
