Overview
The J-H1 (also referred to as the unit in this manual) is
a Digital Videocassette Compact Player based on the
HDCAM
1)
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.

• Since the unit does not have a dynamic tracking
function, the tape may not replay correctly if the
recording patterns on the tape are disturbed.

3/4 inches) of this unit, the playback image may be
disturbed.
