Requirements for measuring analog component HD signal for video devices
The transition to digital has enabled great strides in the processing of video signals, thus allowing a variety of techniques to be applied to the video image. Despite these benefits, the final signal received by the customer is still converted to an analog signal for display on a picture monitor. With the proliferation of a wide variety of digital devices - set-top boxes, Digital Versatile Disk (DVD) players and PC cards - comes a wide range of video formats beside the standard composite output. It is therefore necessary to understand the requirements for measuring analog component High Definition (HD) signals in order to test the performance of these devices.
