隨著網路的普及與嵌入式系統的發展,多媒體的應用也越來越多元化。在這樣的背景之下,我們利用成本低廉的硬體平台搭配網路上免費的網路協定原始碼LWIP來發展出一套具有穩定性的嵌入式系統影音多媒體系統。由於過去多媒體影音系統大部分都在PC平台上,因此具有缺少可攜性與成本過高等缺點,我們透過與嵌入式平台結合的方案,將可以提供一套成本低廉、產品應用面廣與具有強大功能的的資訊產品。
本篇論文以DSC25為硬體開發平台,修改網路上免費之網路協定軟體 – LWIP,並設計一套即時影音串流與善用網路頻寬之機制,使得我們開發出來的產品可以提供品質良好的影音串流服務,另外由於我們所移植的網路協定可以單獨運作於系統平台,因此具有相當的獨立性,相當適合各種不同平台間的產品應用。
With advances in communication, multimedia, and the growth of embedded system,the applications of multimedia become diverse. Base on cost-effective design, we use a low cost hardware with free software – LWIP to develop a stable embedded A/V streaming system.We combined embedded system with LWIP to develop a system which is inexpensive and easy to develop software.
In this thesis, we studied the free software – LWIP, and designed a mechanism for A/V streaming sytem to allow our products can provide better A/V streaming services. In addition, the network protocol and A/V streaming system that we developed is independent of the system, so it is easy to portable to other platforms.
