Embodiment Construction

[0080] The structure diagram of the system is shown in Figure 3. The system is divided into the following modules.

[0081] 1. Metadata retrieval server;

[0082] Metadata is the text information manually filled in when making a program. It is used to describe the content information such as the title, director, actor, production place, and introduction of the video program, as well as characteristic data such as frame rate, resolution, on-demand fee, and whether DRM verification is required.

[0083] This part is the only module in the whole system that requires manual participation.

[0084] After manually filling in these data, enter them into the metadata database.

[0085] When performing a simple metadata query, or performing a content-based query and needing to search for related information, a retrieval request must be sent to the metadata retrieval server to query the metadata database.

[0086] 2. Subtitle retrieval server;

[0087] The obtained subtitle feature ...

Abstract

This invention provides a search system based on video program content characters including a search dispatch server used in analyzing and dispatching the search requests put forward by users to search in terms of a certain strategy to grade, arrange and merge the search result to feed them back to the user, an element data search server searching the element data of the video program based on the requirement of the server, a caption search server searching the XML file storing program caption texts, a video search cluster used in searching the character data of the video key frame, a phone search cluster used in searching the phonetic information of video programs including spelling series and spelling patterns and a search interface facing to users receiving request of users in terms of signed message format and feeding back the search result.

Description

technical field [0001] The present invention relates to the field of content-based video retrieval (CBR). Including the organization and storage of video feature data, the indexing and retrieval of high-dimensional feature vectors, distributed retrieval and other technologies. Background technique [0002] An information retrieval system usually includes a core retrieval database, a search scheduling server and server groups. Externally, it provides an interface for searching and information entry. As shown in Figure 1. [0003] Among them, information entry mostly relies on manual typing. That is, the provider of the retrieval content in the system enters the content information provided to the user and used for searching into the database through the information entry interface of the retrieval system. [0004] The core database system is mainly responsible for storing information data for user retrieval. [0005] The search scheduling server is responsible for receiv...
