Design and implementation of a Java H.263/G.726 decoder.

Abstract

In this thesis, we present a decoder that is capable of performing real-time decoding of video and audio streams on Java-enabled platforms. We decompose the design phase into two stages: the declaration of design objectives and the proposition of a high level design. The design objectives are to build a decoder that is efficient, small in size, and adaptable to different platforms and network environments. The high level design is composed of key algorithms and major building blocks of the decoder. We document some challenges encountered during the implementation phase, some of which required revision of the initial design. We conduct test cases under some representative network environments to demonstrate the adaptability of the decoder. Lastly, we identify the work areas to be extended.
