The J-H1 (also referred to as the unit in this manual) is a Digital Videocassette Compact Player based on the HDCAM1) format.

For monitoring, this unit uses a down-converter so that you can check the recorded images even in the SD environment. This feature allows you to monitor images easily using a commercial TV (HD/SD) or PC display.

HDCAM format

In the HDCAM format, as in the Betacam series, a recorder can record up to two hours of HD high- quality images using a 12.65 mm-width tape.

For compressing video signals, this format employs a pre-filter and coefficient recording technology.
