Design and implementation of ONVIF-based event service for DM 814x camera

초록

Nowadays, IP-based physical security products like IP network camera (IPNC) are becoming essential in construction of a modern security system. In order to guarantee interoperability among them, ONVIF has been a de facto standard communication framework. In addition to core specification, ONVIF defines many services. ONVIF Event service is supposed to provide notification messages to registered clients when events happen, which is an essential mechanism to be support to make IPNC intelligent. Currently, we are developing a smart IPNC based on TI DM814x media processor. In this paper, we report our efforts to implement ONVIF Event service for the smart IPNC. First, we design S/W architecture, necessary data structures, and workflow of ONVIF Event service according to ONVIF Event service specification. Then, we implement the design about ONVIF Event service by extending TI's IPNC reference RDK S/W package. Testing via an Open source ONVIF client verifies our implementation works properly. © 2015 IEEE.
