ONVIF（開放式網路視訊介面論壇）是目前監控產業的重要國際標準，其標準旨在促進不同品牌網路視訊監控設備間的整合，並幫助生產製造商、軟體開發商及獨立軟體供應商確保產品間的可互通性。為了達到此目的，ONVIF致力於將各種網路視訊監控管理與控制介面標準化。由於網路視訊監控設備的種類眾多，因此為了能將ONVIF所提出的標準介面順利移植至各種網路視訊監控設備的硬體平台上，必須設計富彈性之平台抽象層與硬體平台介接。本文將透過分析ONVIF標準和服務，來說明平台抽象層規劃的重點，並以此進行平台抽象層的系統設計，最後透過實際移植案例與效能測試說明其可行性。

ONVIF (Open Network Video Interface Forum) is an important international surveillance industry standard, the standard is intended to promote the integration of network video surveillance equipments of different brands and to help manufacturers, software developers and independent software providers ensure interoperability between their products. In order to achieve this purpose, ONVIF is committed to the standardization of a variety of network video surveillance management and control of interface s. A flexible platform abstraction layer has to be designed in order to facilitate the porting of the ONVIF standard interface to the hardware of a variety of surveillance devices. Through the analysis of ONVIF standards and their services, we illustrate the planning and system design of the proposed platform abstraction layer, and finally we show the feasibility of it through actual porting cases and performance testing.
