EMC: AS/NZS 3548

This unit was designed for use under controlled EMC environment (for example
purpose built broadcasting or recording studio), and the rural outdoors environ­ment (far away from railways, transmitters, overhead power lines, etc.).

FCC 47 Part 15 Class A
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to the part 15 of the FCC Rules and EN 55022. These limits
are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harm­ful interference to radio communications.

Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interfer­ence at his own expense.

The EMC regulations are only applicable when correctly shielded cables are used
for installation of the equipment. This applies to video cables as well as control
cables. Corresponding cables can be obtained from Thomson.
Run all connection cables in covered cable ducts (risk of stumbling).

The DCR 6024/6128/6000 includes wide range power supply units of 100 – 240 V,
so that no changeover is required for different line voltages. Depending on the sup­ply voltage use the proper rated power supply cord.

For more details see section 5 ”Installation” in the Planning & Installation manual.

Caution! Double-pole or neutral fusing

Risk of electric shock. Grounded circuit conductor (neutral) provided with over-cur­rent protection.
After operation of the protective device, parts of the equipment that remain under
voltage might represent a hazard during servicing.

Disconnect power before servicing!

The Tapedeck DMS 6000 is protected by two primary-side fuses (T6.25A / 250V)
which are located on the rear panel.

When replacing this fuse, make sure that a fuse link of the same type and of the
same current rating is used.
Never use a mended fuse! Do not short-circuit the fuseholder!

1.1 FEATURES

1.1.1 GENERAL

Digital film and the 1080p universal mastering format are increasingly important in
post production applications. Besides the digital HD video formats the data format
using SMPTE–rated DPX ( digital picture exchange) file format for uncompressed
storage and transport of picture information is required. This data format allows
higher resolution than specified in video formats with similar freedom in transfer
characteristic, color space and so on.

The DCR 6024/6128/6000 supports the HD video formats (1920x1080) as well as
data recording of DPX picture information. Using the same tapedeck and different
processors for DTV and data applications the system can be configured for the
requested application. With the addition of the data switch the same tapedeck can
be used to record data or digital HD video in many formats.

Planning and Installation – Rev. 1 / 7. 2001

1.4 MACHINE CONTROL

The control of the DCR 6024/6128/6000 is based on a user-friendly menudriven
concept. The menus are selected via 12 dedicated keys. All menus (except Setup,
Diagnostics and Editor) are designed without any sub menus to ensure easy
handling.

The menues are application sensitive, Depending on selected modes (data or
video) and installed options there are different menues and controls available.

12 softkeys control different functions in each menu replacing a high number of
dedicated keys.

All analog adjustments are done by a digipot which function varies with the different
menus (for further informations see chapter 4 “Menu Control” in the “Operating In­structions” manual).

A unique feature for VTR’s is the availability of a credit- card sized personal card
which can be inserted in a slot on the control panel. All machine parameters and
setups accessible from the control panel can be stored on this card. Information are
stored at this card in a S-RAM buffered by a 3 V lithium battery so that it can be
loaded everywhere into the recorder. If required, the stored machine setups and
adjustments can then be recalled.

The track pattern of the recorder contains the helical tracks with the video and au­dio sectors (DTV mode) and rewrite area (data mode) divided in clusters of 8 tracks
each.
It is based on azimuth recording with a track pitch of 22 m which allows a max re­cording capacity of 64 min or 500 GBytes with a L-type cassette.
The clusters are separated by guard bands from each other, allowing proper erase­ment of the individual clusters with a single flying erase head for each cluster .

One field is the minimum edit distance for video audio and data in DTV mode. It is
divided into six (24/25 Hz) or five (30 Hz) clusters respectively. In data mode the
sytem uses the 25 Hz mode internally .

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 heli­cal 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 for­mat.

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, parti­tion–no. and tape length.

The DCR 6024 uses 1 1 µm 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 multi­channel 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.

The DCR 6024/6128/6000 offers a confidence playback facility for video and audio
tape monitoring during record in DTV mode. In data mode, confidence playback is
used to check the recorded data and rewrite if necessary.

Digital recording and playback in conjunction with sophisticated error correction re­sult in excellent picture and sound quality in DTV mode. Even after 20 tape dubbing
generations there will be no noticeable loss of quality.

The DCR 6024 includes a very powerful error correction facility with a total output
error rate of 10

-11

.

A two step error correction system, based on the Reed Solomon Code is imple­mented to correct data reading errors.
There are two types of errors:

 Single errors
 Burst errors

In data mode (DCR 6128) the error correction capabilities are increased once
more. In conjunction with a rewrite function, controlled by the result of confidence
playback functions the corrected bit error rate (BER) will be in the range of 10 E–17.

In both modes the playback quality is checkable by the ”Channel Condition” indica­tors (LEDs) and/or by the display of the ”ADJUST” menu.

The ”Inner-Code” is used to correct up to 7 single errors in each datablock of 227
bytes (DTV mode) or 230 Bytes in data mode.
With the restriction that the off tape bit error rate is smaller than 10

-4

and no burst

errors occur, the residual error rate after ”Inner correction” will be less than 10

-16

.

This is about one million times better than D-1 format VTR performance.

Due to scratches and tape drop outs, not only single errors but also large burst er­rors can occur . To overcome this problem the DCR 6024/6128 has a powerful ”Out­er-Code” too.
Extensive burst errors up to 141 648 bytes of data could be corrected in DTV mode
by ”Outer correction”. That is 25 times more than a D-1 format recorder can.Using
advanced integration techniques the most powerful error correction of existing digi­tal video standards is implemented in the DCR 6024.

In data mode (DCR 6128) the “Outer correction” is more than twice as powerful
as in DTV mode. In conjunction with the rewrite function during record the corrected
BER will be in the range of 10 E–17.

If the capacity of the error correction system is exceeded by larger defects, an error
concealment function becomes active which covers the defective data.

The iMCS control interface is designed as Cheapernet-based control link (IEEE

802.3 standard) between machine(s) and control panel(s).
This interface can be used to interconnect up to four machines. Such a cluster con-

figuration allows the design of cost-effective operating configurations as only one
control panel is required to operate several machines.The integrated two-machine
editing system of the DCR 6024 uses the iMCS (2-machine cluster) as a control link
when editing with two DCR 6024.

In data mode (DCR 6128) the iMCS interface is used to control the data recorder
from telecine controllers or workstations.

1.6.2 DTV PROCESSOR DTV 6024

Digital serial input signal is a serial data stream composed of digital samples of a
component video signal Y / PR / PB.
The signal formats for video are described in the SMPTE 274M. SMPTE 292M de­scribes the signal parameters for serial interfaces.

The system uses an 10(8) bit quantization for Luminance and a 8 bit quantization
for chrominance.

SCCV Scanning Converter

The digital serial video input signals are fed to the board SCCV . The signal is con­verted from serial into parallel. Progressive signals are converted into a segmented
signal. For progressive and segmented frame modes (24, 25, 23.97 fr/sec) 2 LSB
bits from the 10 bit Y are separated and stored in a memory and inserted as lines
of the frame. In case of 8 bit signal processing and 10 bit input, a rounding process
is integrated.

VINP Video Input Processor
The selected input data are fed to the serial parallel converter and converted into

4 channel parallel luminance data (Y) and 4 channel chrominance data (Pb/Pr).
After line shuffling, parity bytes for the outer error correction coding are added.

CODC 1-4 Inner Coder/Decoder

The coded data are fed to the board CODC. On this board, the coded data are fur­ther shuffled in a field basis.

After mixing with the audio data, parity bytes for the inner error correction coding
are added.

In the channel encoder, the eight bits data are transformed into 12 bits data, then
the sync words are added.

A head delay compensates for the timing difference between each channel,
caused by the difference of the mechanical position of each head on the head­wheel.

Finally, the data are converted to serial data (8 channel record data, 2 bit parallel),
and sent to the Tapedeck as ”record data” via the buffer board I/O1.

The digital audio interface meets the AES-/EBU- standard AES 3, 1992.
A total of 12 (10) channels or 6 (5) stereo pairs is available for the digital recording

of audio signals, it uses a sampling frequency of 48 kHz and 20 to 24 bit linear quan­tization.

AINP Audio Input

The recording signals are fed to the board AINP. The segment memory stores the
recording signals temporarily to establish the segmented recording signal format,
which corresponds to the audio data block for error correction coding. Readout sig­nal from the segment memory is supplied to the Read-Solomon encoder which cal­culates outer parities for the audio data. The encoded output signal is stored in the
shuffling memory. This memory generates the first and the second recording data
with different shuffling schemes in a unit of inner code word.
The first and second recording data are transmitted to the board CODC to be multi­plexed into video data.

CODC Encoder / Decoder

The serial data are fed to the decoder board CODC via the board I/O1 from the Ta­pedeck. In this board, the serial data are converted into parallel form, and fed to
the TBC (Time Base Corrector) to reject time base errors. The sync pattern are de­tected from the reproduced data in the sync detector circuit. The channel decoder
converts the 12-bit modulated data into 8-bit data. The inner decoder performs
detection and correction of errors. The audio data are separated after inner error
correction.

VDFM Video Playback Processor

In the board VDFM, the field deshuffling is done in a field basis, then the outer error
correction is carried out.

VOUT Video Out Processor

The corrected data are fed to the board VOUT. In the board VOUT, the data is re­arranged into the original data arrangement after the line deshuffling and channel
deshuffling.The concealment circuit is provided to interpolate the data in case that
the data are not fully corrected by using the outer parity. By using the surrounding
non-erroneous pixels the erroneous data are interpolated. The video sync data are
added to the blanking interval then the data are converted from parallel form to se­rial form, and fed to the board SCCV. If the digital I/O option (available only for 60i
and 59.94i) is installed the digital signal is fed to the output connector.

SCCV Scanning Converter

The digital parallel signal coming from the VOUT board is converted from a seg­mented format to the selected output format. Lines containing 2bit Y are stored
in a memory and added to the Y signal. A parallel to serial converter generates the
output signal according to SMPTE 292M standard.

A video monitoring circuit generates an analog output signal (Y, PR, PB, Sync) or
R, G, B, Sync according to the selected standard.

AOUT Audio Out Processing

The board CODC supplies reproduced audio data to the board AOUT .In the board
AOUT, the reproduced data and inner decoder flags are stored in the deshuffling
memory. Storing operation is permitted when the reproduced data are likely to have
correct inner code block addresses. When the storing is inhibited, a new/old flag
is set to ”1” for corresponding inner code block in order to avoid misdetection by
older correct inner code block.The first and the second recording data are readout
from the deshuffling memory by turns in a unit of symbol. Then, for each data sym­bol, optimum one is selected to achieve optimum outer code word. This code word

is fed to the Reed-Solomon decoder for error detection and correction. The de­coded output data are stored in the segment memory to get an audio data se­quence. The error concealment and the level control are applied to this sequence.
(AES/EBU interface encoding is applied to the audio data, and the encoded data
are output through rear panel connectors as audio digital output signals)

Analog Audio Option, Audio Monitoring Option

Two channels are available on the audio monitor output through the output connec­tors of the rear panel and the headphone jack in the Tapedeck.The monitor signals
can be selected from the input or reproduced audio signals, the aux input signal,
the cue record signal and the cue playback signal.

The SYSC board consists of System Control block and Sync Generator block. The
System Control block controls the system, communicates with the Tapedeck and
outputs superimpose data. The sync generator block consists of a diverse sync
signal generator, a system clock regenerator, a playback sync signal phase ad­juster, a NTSC / PAL sync signal generator and a channel clock generator circuits.
The timing of every synchronizing signal is completely switchable to meet each HD
standard.

1.6.3 DA TA PROCESSOR DDP 6128

To prevent major modifications in the tapedeck, one of the existing video modes
is for data recording. When in data mode, the tapedeck runs internally in a video
mode (50Hz). So all tapedeck functions like servos, timecode units can be re­mained unchanged. Only the system software has to be modified for data version.

HPIF Board (HIPPI–Interface)

The optical signal is fed from the input to this board. This board is responsible for
communication with external Hippi devices. A conversion from optical serial signal
to electrical parallel signal is made. A buffer of 128 MBytes allows a flexible han­dling of incoming data stream. The Hippi header is detected and analyzed. The
header is removed and the data is provided to DPSC board.

DPSC Board

On the DPSC board the internal data controls are processed. Control information
like helical address information (HAI), table of content (TOC), partition information
(PSIT) is generated and inserted in data stream. All required clock generators are
located on this board. The incoming data packet is distributed and segmented into
8 channels.
This board contains also the system control unit.

CORE Board

This board is responsible for the standard digital recorder signal processing steps.
The functions are comparable with the CODC board of the DTV processor. Each
board contains 4 channels, so two identical boards are used in the data processor.

The Reed Solomon error correction encoder adds check bytes to the data bytes.
A rewrite memory stores data and inserts this data again if a rewrite due to error
rate is required.

After channel coding and conversion from parallel to 2bit serial mode, the data is
fed to the tapedeck.

CORE Board

The playback data stream (8channels) is fed to the two boards. Similar functions
compared to the CODC board are implemented:
Channel decoding
Sync detection
Error detection and correction.
For the rewrite function, a error information for rewrite decision is generated.

DPSC Board

The DPSC board extracts and processes all control information that was inserted
in the data stream during record (HAI, TOC). The data signal is combined from the
8 channels.

HPIF Board

The playback data signal is prepared for Hippi transfer. signal information (size) is
analyzed and a Hippi header is generated. Communication with Hippi destination
device is started and data is sent via optical transceiver. For playback mode the
same buffer memory of 128 MBytes is used.

DPX Monitoring (Option)

If the incoming / outgoing data stream is detected as DPX data, the signal is fed
to the DPX monitoring board. This board is located on the HPIF –board. The out
put of this board is a standard XGA signal (1024x768 / 80Hz). The DPX data is con­verted into an XGa signal. If the resolution of DPX signal is lower than XGA resolu­tion, the complete picture is displayed. If the resolution is higher, the resolution is
reduced by skipping lines and pixels. Because this is only a monitoring feature
boarders may appear on the screen depending on DPX resolution.
In record mode, this board is connected to the input data stream, inplayback mode,
the board is connected to the output data stream.

DPCU System Control

The system control is responsible for the control of all boards and the communica­tion with tapedeck via iMCS. For service mode a RS232 serial port is installed. Soft­ware updates can be done using this port to reprogram the flash Eproms.
