| Popis: | 85 MPEG-4 將以物件為基礎的 ( object-based ) 壓縮方式來打破目前的限制，並開發更 多的多媒體應用。 MPEG-4 的最終目標是想將無線通訊資料，電腦合成資料，和電視影音 資料均能整合於同一應用中，進而制訂出統一的儲存和傳播的規格。本論文以MPEG-4 的 視訊部分做為MPEG-4相關研究的開端，並展示出MPEG-4的雛型和所包含的觀念。 第一章 描述 MPEG-4 的應用範圍, 第二章描述其演算法, 第三章將展示一個 Java 為發展工具的 解碼器, 第四章概述其編碼器之設計, 最後一章為結論. With the success of the MPEG-1 and the MPEG-2 coding standards, digital tel evision is possible today. The newest action of the MPEG committee is to devel op the MPEG-4 standard for multimedia communications. This group aims at provi ding a standard in order to cope with the requirements of current and future m ultimedia applications. The first part of this thesis describes what kind of m ultimedia applications MPEG-4 intends to establish.The Second part of this the sis describes MPEG-4 video encoding and decoding algorithms in the Verificatio n Models, and its functionalities such as object-based coding, user interactio n, decoding downloadability, spatialand temporal scalability, etc.. In the thi rd chapter, a Java-based software video decoder is presented. The forth chapte r describes the implementationof the proposed software MPEG4-like video encode r. In the end of this chapter, the performance of the encoder is presented. |
