One of the most impressive and attractive evolutions of DVD recorder is the remotely controllable ability. In this paper we concern about the verification of remote controllability of latest DVD recorder by Internet or dial-up network, through RJ45 and RJ11 sockets respectively during manufacturing process. The virtual instruments tools, LabVIEW and TestStand are used to form a function module of the whole measurement system. The detailed procedures are given and G-codes are depicted. Some human-machine interfaces are captured to show the process. The developed modules is successfully put into use.

This paper firstly focuses on the video signal measurement system for DVD recorder, one of the most demanding tasks for DVD recorders manufacturing. An online measurement system is configured and set up by PC workstation and LabVIEW, a virtual instrument development platform. After that, the system is put into practice successfully. Some deficient video signals are captured and their image and waveforms are illustrated. The causes behind the deficiency are further analyzed. The online measurement system becomes an essential tool to guarantee the quality of DVD recorders before packing.
