[0058] In the first embodiment of the present invention, a method for generating an index, such as Image 6 shown, including the following specific steps:

[0059] Step S101, classify the description information of the content of the media file to generate content set index, content description index, content association index and content policy index. The data model of the index is as follows: Figure 5 As shown, the content set index can be associated with 0, 1, ... or n content description indexes, and the content description index is respectively associated with a content association index and a content policy index, and the content association index A reference is associated with 1, 2, . . . or n media file contents.

[0060] Content set indexing: A description of clustering and composition based on operational requirements and supporting media content. A single content set has a unique content set ID (Content Group ID). The content included in the content set index is ...

[0081] In the second embodiment of the present invention, a device for sending media files based on indexing, that is, the front end of the DVB system, such as Figure 8 shown, including the following components:

[0082] 1. Content Provider

[0083] The content providing server is used to provide media file content to the advertising server.

[0084] 2. Broadcast server

[0085] The structure of the broadcast server is as follows: Figure 8 As shown in the figure, the broadcast server at the front end unidirectionally pushes the content of the media file to the terminal. The workflow of broadcasting server, first obtains content from content providing server, is managed by content management module, then according to the information provided by content, generates index in indexing generating module according to the requirement of this broadcasting task. In the task generation module, the content policy index is adjusted according to the content index information and the u...

[0123] In the third embodiment of the present invention, a method for sending media files based on indexing, such as Figure 13 shown, including the following specific steps:

[0124] Step S201, generating an application index and a network index according to the description information of the content of the media file;

[0125] Step S202, collecting user subscription information or user behavior information from the terminal, and adjusting the content policy index and the content of the media file broadcast this time accordingly;

[0126] In this step, the process of collecting user subscription information from the terminal is:

[0127] The front-end broadcast server sends the preview FDT table to the terminal through the one-way network. The preview FDT table includes three application indexes: content set index, content description index and content policy index;

[0128] After the user's preview is over, the terminal sends the user subscription information to the intera...

Abstract

The invention discloses a method for generating an index and a method and a device for receiving and sending a media file based on the index. A front end generates an application index and a network index according to description information of a content of the media file; a broadcasting server collects user subscribing information or user behavior information by a bilateral network from a terminal so as to regulate the application index, the network index and a content of the broadcasted media file; and the content of the broadcasted media file and the regulated network index and applicationindex are packaged into a transmission data message and the transmission data message is sent to the terminal by an unilateral network. Compared with the prior art, the invention increases a feedbackmechanism between front end equipment and terminal equipment, sufficiently utilizes the existing unilateral and bilateral coexistence transmission network and can make the front end carry out real-time regulation on the broadcasted media content file according to the requirement of a user.

Description

technical field [0001] The present invention relates to the technical field of DVB (Digital Video Broadcasting, digital video broadcasting), in particular to a method for generating an index and a method and device for sending and receiving media files based on the index. Background technique [0002] The FLUTE (File Deliver over Undirectional Transport) protocol is an IP-based point-to-multipoint file transfer protocol (rfc3926), which is widely used in various transmission systems, such as IP data broadcasting in DVB. The FLUTE protocol provides functions such as congestion control and error correction for the one-way transmission of multiple files, ensuring the reliability of one-way transmission of files. [0003] In the FLUTE protocol, the transmission object TO is an independent unit transmission entity, each transmission object TO has a transmission object identifier TOI, and multiple transmission objects are in one transmission session TS. like figure 1 As shown, t...
