Method for retrieving and acquiring digital home resources

Abstract

The invention discloses a method for retrieving and acquiring digital home resources. The method is characterized by comprising the following steps that a management server acquires image metadata, video metadata, audio metadata and a metadata directory from a data node to form a multimedia resource virtual set; a user initiates a multimedia resource search/ retrieval request through a search terminal; the management server filters multimedia data irrelevant to the search or retrieval request according to the virtual set and information of the metadata directory and calculates a candidate set; an execution node finds out multimedia metadata meeting a search condition from the candidate set, calculates similarities of the multimedia metadata and ranks the multimedia metadata according to the sequence of the similarities; the execution node returns a search or retrieval result to the search terminal; and the search terminal sends a resource acquisition request according to the received search or retrieval result and acquires appointed multimedia resource through the execution node.

Description

technical field [0001] The invention relates to the field of fast retrieval of network resources, in particular to digital family resource retrieval and resource acquisition methods. Background technique [0002] The resources of the digital home are different from the network resources of the traditional Internet. It mainly includes multimedia resources such as audio, image and video. In the retrieval of traditional Internet network resources, such as Baidu, Google, etc., users input keywords through the portals provided by them, and then Baidu and Google platform servers directly respond to retrieval requests, execute retrieval algorithms, and finally form retrieval results. [0003] Since the resource files of the digital home are relatively large, such as high-definition video, if the current traditional mode of centralized storage to the server is used, a huge storage space will be required. Therefore, the preferred resource storage mode for digital home network resour...

Problems solved by technology

[0004] Existing network resource retrieval methods such as patent 200710100309.8, a network resource retrieval method and system, it creates a webpage index, and creates a resource index corresponding to each webpage for the resources contained in the webpage; receives the retrieval keyword input by the user , and query webpages matching the keywords in the webpage index; query the resources contained in the webpage in the resource index; display the retrieval results containing the webpage information and corresponding resource information to solve the existing webpage information retrieval, In order to solve the problem of being unable to obtain resources quickly and accurately, which consumes users' time and energy

However, the resources retrieved by this kind of network resources are all stored in the server, and the resource retrieval mode between servers cannot be escaped.
