DVD Recorder's Audio Signals Online Evaluation Method and Its Measurement System Implementation

This paper has investigated the online evaluation method for DVD recorder's audio signals and then, based on the virtual instrument technology, set up a system to implement DVD online audio test. The evaluation parameters are explained thoroughly, and their algorithms are illustrated as well. Finally, with the power of virtual instruments, a high-stability and high-speed DVD online measurement system has been developed and the total test time is dramatically reduced.
