1 – 14 Planning and Installation – Rev. 1 / 7. 2001
In DTV mode, twelve (ten) digital audio channels are independent editable in six
(five) stereo pairs.
An edit gap between audio and video sectors allows a separate editing of audio and
video.
The audio sectors are recorded on the top (1st record) and on the bottom
(2nd record) of the helical track for additional error correction.
In data mode there is a special rewrite area at the beginning of each track. In this
area, sync blocks with detected errors during recording will be written again.
An additional Sync block located at the beginning of data area contains the HAI
(Helical Address Information). In this block all control info about the content of heli-
cal tracks like TOC (Table Of Content), and packet info is written.
One longitudinal analog audio cue track (only used in DTV mode), the control
track and the time code track complete the track configuration of the D-6 tape for-
mat.
The recorder DCR 6024 is capable of recording various progressive, “segmented
frame” or interlace standards. HD Standard (frame rate) selection is made in the
”SETUP” main menu.
The selected standard is indicated by the system status indicators at the Control
Panel, LED ”frame rate” (either 24/25 Hz or 30 Hz).
In data mode the timecode track is used to locate and identfy data and system
tracks of data recordings. On tape, a standard 25 fps SMPTE timecode is used.
For the internal control interface this information is translated into a TSID (Track
Set ID). each timecode frame is one TSID. This TSID is used for display, internal
and edit controls.
Timecode 02:00:00:00 is coverted into TSID 00000
Each new partition starts with an offset of 02:00:00:00
The UserBits contain information about type of tracks, file–no., record mode, parti-
tion–no. and tape length.
The DCR 6024 uses 11
µ
m thick D-6 tapes in three different cassette sizes S, M,
with a maximum recording time of 64min.
The magnetic tape specifications (type of cassette, tape thickness) are detected
and interpreted automatically after the cassette has been loaded.
Other 19 mm cassettes ( D-1 or D-2 type), not coded according to the D-6 format
will be rejected by the DCR 6024 recorder.
Another coding of the cassette prevents unintentional erasure of the cassette.
Use only tapes specified by Philips and Toshiba.
It uses the D-6 recording format, developed and supported by Philips Digital Video
Systems and Toshiba.
This format is based on a digital segmented-field video recording system with multi-
channel audio using a 19 mm cassette housing, ( S, L and M) with enhanced 11
m
MP tape.The robust segmented tape format with the high sophisticated digital
Processor guarantees a reliable production and transfer recording standard for the
various standards.
