Embodiment Construction

[0016] In order to understand the present invention more clearly, the technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings. As shown in the figure, the streaming media retrieval system in the distance teaching field based on MPEG-7 of the present invention is made up of feature extraction / storage end, streaming media middleware and client, and feature extraction / storage end calls and RTP / RTSP flow through ADO database The media transfer protocol is connected with the streaming media middleware, and the streaming media middleware is connected with the client through the RTP / RTSP streaming media transfer protocol and the TCP / IP network. The feature extraction / generation / storage end is responsible for the automatic extraction / manual labeling of features, using the self-defined MPEG-7 description mode to generate a standard format, and then storing it in the XML database. The streaming media middleware...

Abstract

The present invention belongs to the field of multimedia application technology. The flow media search system in teleteaching domain based on MPEG-7 has characteristic extracting/storing end and flow media intermediate, the characteristic extracting and storing end is connected to the flow media intermediate via calling ADO data base and RTP/RTSP flow media transmission protocol, and the flow media intermediate is connected to client end via RTP/RTSP flow media transmission protocol and TCP/IP network. The characteristic extracting/creating/storing end completes the automatic characteristic extraction and the manual labeling; and the flow media intermediate converts the inquiry of the client end into the XQuery syntax inquiry to XML data base. The client end provides the users with convenient multimode inquiry interface, records user's information and sends the inquiry request and personal file to the flow media intermediate.

Description

technical field [0001] The invention relates to a streaming media retrieval system in the field of distance teaching, in particular to a streaming media retrieval system in the field of distance teaching based on MPEG-7 (the Chinese professional term is "multimedia content description interface"), belonging to the field of multimedia application technology. Background technique [0002] The current development of multimedia technology has led to a rapid increase in the available multimedia data. However, how to extract useful information from these multimedia contents and construct a practical system has become a recognized problem. The biggest obstacle is the lack of a simple, understandable and extensible multimedia description to construct efficient, extensible and scalable multimedia application. Such as: After searching, it is found that the U.S. Patent No. US2003103675, the patent name is "Multimedia information retrieval method, program, record medium and system (met...
