The Design And Implementation Of System Of Multimedia Content Management And Visualization

With the vigorous development of the multimedia, audio recognition technology and video image processing technology is becoming more and more mature. The practice laboratory of me has made a series of research results in speech recognition, language recognition, sound recognition, word recognition, and emotion recognition. The main function of multimedia content analysis and visual display system lies in integrating these research results, forming a holistic, systematic multimedia platform, and offering a parallel analysis of a speech in the speech content, language, content, content, content, emotional content, which can visually display the use of information visualizat ion technology.This paper gives a detailed introduction of the main technologies and methods of multimedia content analysis and visual display system design and development. The subsystem of multimedia content analysis contains some key functions such as the decomposition of multimedia streams, multimedia audio stream extraction, segmentation, multimedia audio recognition module integration, video image capture, caption detection, image segmentation, word extraction, and streaming video rendering play; Multimedia content visualization mainly contains the key functions of the content of the speech, the content of language contents, sound, words, emotional content, the results of the above content retrieval visualization and multimedia player; Multimedia cont ent management mainly completes the audio recognition related data, subtitle data management, and defines the storage format of multimedia audio recognition module output. The framework that multimedia stream processing system adopts is Direct Show, which provides a set of Microsoft on Windows platforms of multimedia processing development kit and many convenient methods for multimedia stream processing. Developers can use Direct Show technology to customize specific components according to the needThis system adopts the testing method based on the example to verify the functional requirements, the key functions of the test link, and do a lot of testing work, in order to ensure the accuracy and stability of the system function. Test results show that the system has realized the function requirements, and owns good stability and practicability.
