1-1 Features Chapter 1 Overview Compact design Since the unit is as compact as a standard desktop personal computer in size, it is ideal for personal use on your desktop. In addition, front loading of both S and L cassettes is standard. Menu-based setup Initial settings for the unit's operation, interfaces with connected equipment, and so on, can be made by means of menu operations on the front panel of the unit. A wide range of status indicators A large-sized fluorescent display is provided to show numerical values including audio level, time code, user bits, error messages, and setup menu information in addition to the current settings and operating status of this unit. Minimal maintenance The unit is designed to need minimal maintenance, and requires no daily maintenance or checks. A drum and other components have reduced maintenance costs. Vertical installation This unit can be installed vertically using the supplied vertical installation stands. The unit can be installed either vertically or horizontally, saving space on your desktop. 1) (DV) output (available only when an HKJ-101 i.LINK1) Interface Board is installed) When an optional HKJ-101 i.LINK Interface Board is installed, this unit can output digital video/audio signals in DV format compatible with i.LINK from the DV output connector. Note The 2-3 pulldown sequence process is guaranteed only during playback in PLAY mode. Time code multiplexed to pull down signal output • The value of the time code multiplexed to pull down HD SDI output signal is determined by the time code preset using 24F TC A-FRAME SELECT, extended menu item 623 and 30F TC A-FRAME SELECT, extended menu item 624, and then converted from 23.98-frame into 29.97-frame time code. • Time code data of the user's bits area is not output when the 23.98PD system functions. The time code value before conversion (23.98-frame mode) and sequence information of conversion contained in user's bits data are multiplexed to the HD SDI output signal. The following four bits are used for the sequence information to display 0 to 9 repeatedly. MSB: The first bit of the tens digit of the hour The second bit of the tens digit of the hour The first bit of the tens digit of the minute LSB: The first bit of the tens digit of the second When the sequence information is masked, the remaining contents of user's bits data are the same as the time code value before conversion (23.98-frame mode). Note Since user's bits data multiplexed to the downconverted output signal are updated frame by frame, 23.98-frame time code and sequence information of the down-converted output signal differs from those multiplexed to the HD output signal. Time code area 29.97F TC User's bits area (HD) 23.98F TC + sequence information A frame 2-3 pulldown sequence (J-H3 only) If you set the system frequency to 23.98PD, you can output 59.94i video signals while a tape recorded in 23.98PsF is being played back. The following is the 2-3 pulldown sequence.
