Description

Play material publishing method and system in IPTV system

Technical field

The present invention relates to the field of IPTV services, and in particular to a method and system for releasing a playback material of an IPTV system.

Background technique

Internet Protocol Television (IPTV) refers to an Internet (Internet Protocol)-based TV broadcasting service, that is, an interactive network television. It is a broadband cable television network that integrates Internet, multimedia, and communication. Technology, a new technology that provides home users with a variety of interactive services, including digital TV. It can adapt well to the rapid development of today's networks and make full and effective use of network resources.

In recent years, as the IPTV market matures and users continue to grow, the number of users at each site has reached hundreds of thousands. Under the premise that there are a large number of users and a large amount of playback material requirements, how to quickly and efficiently release the playback material of the IPTV system is the main problem currently facing.

In the current IPTV system, the release of the playback material includes three steps. One is to put the playback material provided by the content provider into the library of the management platform, and the second is to publish the playback material in the management platform library to the central node. The third is to distribute the playback material from the central node to the regional node. The play material includes but is not limited to audio and video files, picture files, text files, and the like.

However, the problem with this material publishing method is that the content of different content publishers must be placed in the library of the management platform in order to continue publishing. When there are a large number of urgent playback materials to be published, the content must be released. The player's playback material is placed in the management platform, and the management platform releases the serial operation, resulting in an efficiency bottleneck. In addition, when the playback material is released, it must be forwarded through the central node. A playback material passes through the management platform library, the central node, and the regional node, and is copied three times to complete the release, which is inefficient.

Summary of the invention

An object of the present invention is to provide a method and system for releasing a playback material in an IPTV system, However, in the prior art, under the premise of a large number of users and a large amount of playing material requirements, the publishing material has low publishing efficiency, many links, and slow speed.

Preferred embodiment of the invention

The technical solutions of the embodiments of the present invention are further described in detail below with reference to the accompanying drawings and embodiments.

FIG. 1 is a block diagram of a publishing system for playing materials in an IPTV system according to the present invention. The distribution system includes a content provider library 10, a control platform 20, a central node 30 for material distribution, and a regional node 40 for material distribution. The content provider library in the figure shows three, and the regional nodes also show three, which is not used to limit the content provider library and regional nodes in the system.

The content provider library 10 is used to store the playback material provided by the content provider, and is the source of the playback material. The control platform 20 is configured to receive, by the IPTV operator, a play material request, where the play material request includes an identifier of the play material, and therefore, the control platform 20 acquires the content provided for providing the play material from the database according to the play material identifier. The source address of the commercial library 10; the destination node address of the playback material is obtained according to the material distribution policy, and the playback material in the content provider library is directly published, for example, directly to the central node 30 or the regional node 40. Due to different material publishing strategies, the destination node address of the playback material is different, and the central node address that can be published for the material and the regional node address that the material is published. The content provider identifier of the content provider library may be multiple in the playback material request, that is, one operator may have multiple content providers. The area node 40 for the material is mainly used for saving the playback material released by the control platform 20 and the central node 30, and providing the IPTV terminal with the material for acquiring the playback material.

The publishing system further includes a central node 30, which is mainly used for saving the playing material released by the control platform, and according to the playing material strategy (for example, the material publishing policy is that the playing material belongs to the designated area, and the playing material request needs to play the material. When the IPTV user belongs to a specified area, the playback material is posted to the central node, and the playback material is posted to the regional node outside the designated area. The central node can provide a playback material service to the IPTV terminal.

The following describes the release of the playback material based on the publishing system of the playback material in the IPTV system described above, to better understand the release system of the playback material in the IPTV system of the present invention. Process.

First, in the control platform of the present invention, a material publishing policy is preset according to actual usage, and the material publishing policy can be three cases:

Strategy 1 (playing material release in the specified area): The material publishing policy is that the playback material belongs to the specified area (that is, the material is released to a certain area according to the actual needs of the user.), the playback material can only be published to the corresponding area node in the specified area. on.

Strategy 2 (Specify the release of the material outside the region): The material publishing policy is that the playback material belongs to the specified area. When the IPTV user who needs to play the material service belongs to the specified area, the playback material is posted to the central node.

Strategy 3 (balanced release of material between regional nodes): The material publishing strategy is to distribute the material in a balanced manner among multiple regional nodes of the IPTV system according to load balancing.

As shown in Fig. 2, it is a schematic diagram of Embodiment 1 of a method for distributing a playback material in the IPTV system of the present invention. As shown in the figure, the publishing method is implemented according to the strategy 1. The publishing method of the playing material includes the following steps:

Step 101: The IPTV operator proposes to release a play material request message on the control platform, and the control platform obtains the content provider chip address, that is, the material source address, from the control platform according to the release play material request message. The release play request message includes the material acquisition mode as the FTP mode, but is not limited to the method, and the release play material request includes an identifier of the material for uniquely determining a material, that is, the control platform can The source address of the material is obtained in the database; Step 102: The control platform acquires the destination node address of the published material according to the material publishing policy. Since the playback material request message is released according to the operator's release, the required playback material is restricted to be played in a certain area. For example, the Nanjing 18 channel is only played in Nanjing, and the other regions are not broadcasted, then the broadcast material of the 18th channel is released to Nanjing. Just fine. The step is specifically that the control platform finds that the playback material requested by the IPTV operator is limited to being distributed in the specified area, so the control platform according to the policy 1 (the playback material belongs to the designated area, and the playback material is posted to the corresponding regional node in the designated area). Obtaining, to the central node, the destination node address is the address of the corresponding regional node in the designated area, because the registration is performed to the central node by each regional node or other manner, for example, manually setting on the central node, the central node knows all the regional nodes. Address; and Step 103: The control platform directly publishes the play material on the content provider library, that is, the source address, to the regional node in the designated area by using an FTP method. The destination node address can be multiple region nodes, which enables one-to-many publishing of the material.

After the control platform publishes the playback material to the zone node, the central node can dynamically adjust the material release. The center node adjusts the release of the playback material according to the actual frequency of playing the material, that is, if the user of a certain area node frequently uses the material on the other area node, the material is also released on the area node, so that No need to acquire material from another regional node, thereby improving system efficiency and saving system resources.

When the IPTV user obtains the play material service, the IPTV user has the area attribute, that is, when the play material needs to be acquired, first acquires it from the associated area node A, and when the belonging area node A does not, acquires it to the central node, if the central node If not, the central node searches for other regional nodes, finds the regional node B that owns the playback material, and then returns the address to the IPTV user, and the IPTV user directly obtains the service from the regional node B. In addition, according to the frequency of use of the user, it is determined whether the material on the area node B needs to be copied to the area node A. For example, if the IPTV user in Shenzhen passes the authentication of the operator of the Nanjing 18 channel in one day, the Shenzhen user Always go to the regional node in Nanjing to get the service, then the control platform can copy the material from the Nanjing regional node B to the Shenzhen regional node A.

As shown in FIG. 3, it is a schematic diagram of Embodiment 2 of a method for distributing a playback material in the IPTV system of the present invention. As shown in the figure, the publishing method is implemented according to the policy 2, and the publishing method includes the following steps:

Step 201: The IPTV operator proposes to release a play material request message on the control platform, and the control platform obtains the content provider chip address, that is, the material source address, according to the release play material request message. The release play request message includes the material acquisition mode as the FTP mode, but is not limited to the method, and the identifier of the material included in the release play material request is used to uniquely determine a material, that is, the control platform can The source address of the material is obtained in the database;

Step 202: The control platform acquires a destination node address of the required play material according to the material publishing policy. The step is specifically that the control platform finds that the playback material requested by the IPTV operator is required to be released in the specified area, and the IPTV user that obtains the playback material service belongs to the designated area, so the control platform is Strategy 2 (playing material belongs to the specified The area, when the IPTV user who is required to play the material service belongs to the designated area, the playing material is posted to the central node) to obtain the destination node address of the playing material to the central node as the central node;

Step 203: The control platform directly publishes the play material on the content provider library, that is, the source address, to the central node by using an FTP method;

Step 204: After receiving the released play material, the central node publishes the play material to an area node of the IPTV user who needs to play the material service outside the area.

As shown in FIG. 4, it is a schematic diagram of Embodiment 3 of a method for distributing a playback material in the IPTV system of the present invention. As shown in the figure, the publishing method is implemented according to the policy 3, and the publishing method includes the following steps:

Step 301: The IPTV operator proposes to release a play material request message on the control platform, and the control platform obtains the content provider chip address, that is, the material source address, according to the release play material request message. The playback material request message includes the material acquisition mode as the FTP mode, but is not limited to the method, and the identifier of the material included in the release play material request is used to uniquely determine a material, that is, the control platform can The source address of the material is obtained in the database;

Step 302: The control platform acquires a destination node address of the required play material according to the material publishing policy. The step is specifically that the control platform finds that the playback material requested by the IPTV operator is not required to issue the release material, so the control platform according to the policy 3 (according to load balancing, the material is distributed between multiple regional nodes of the IPTV system) Obtaining, from the central node, a plurality of regional nodes in the IPTV system as destination node addresses;

Step 303: The control platform directly publishes the play material on the content provider library, that is, the source address, to the plurality of regional nodes in the IPTV system by using an FTP method. The destination node address can be multiple region nodes, which enables one-to-many publishing of the material. When the control platform finds that the load of a certain area node is too large, the material is released to other area nodes, and the playback material is not posted to the area node, so as to share the load.

The playback material request message in the foregoing embodiment 1-3 may include identifiers of multiple materials, that is, requesting acquisition of multiple playback materials provided by multiple content providers, thereby implementing different multiple playbacks of multiple content providers. The material is released concurrently. The content material of each content provider can be released according to the above three strategies.

By using the method of the present invention, compared with the prior art, since the method of directly publishing the material to the destination address from the material source address is used, the intermediate link of the material distribution is reduced, and unnecessary material copying is avoided, so that the material is The release time is greatly shortened.

At the same time, using the invention, the material publishing can be concurrently performed on two levels. First, the material can be simultaneously released from multiple content provider libraries, that is, the material can be concurrently distributed from multiple source addresses; second, a source address can be At the same time, the material is distributed to multiple destination addresses to achieve one-to-many material distribution. Based on the above two points, the present invention realizes a many-to-many release of material distribution, thereby greatly improving the efficiency of material distribution.

In addition, in the present invention, since the dynamic adjustment of the material is used in the central node, it is determined whether or not the material needs to be distributed in the area node according to the use frequency of the material, thereby further improving the use efficiency of the system and speeding up the acquisition of the playback material.

It should be noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and the present invention is not limited thereto. The present invention will be described in detail with reference to the preferred embodiments. Changes or equivalents may be substituted without departing from the spirit and scope of the invention and the claims. Industrial applicability

The invention uses the method of directly releasing the material from the material source address to the destination address, reduces the intermediate link of the material distribution, avoids unnecessary material copying, and greatly shortens the material publishing time. At the same time, the present invention enables the material distribution to be concurrently performed on two levels, and the material can be concurrently distributed from multiple source addresses; and one source address can simultaneously release material to multiple destination addresses, thereby realizing one-to-many material distribution. Achieve a multi-to-many release of material distribution, which greatly improved the efficiency of material distribution. In addition, the present invention uses dynamic adjustment of material distribution at the central node, and determines whether or not the material needs to be distributed in the area node according to the frequency of use of the material, thereby further improving the use efficiency of the system and speeding up the acquisition of the playback material.
