PROTECTING YOURSELF AND THE V1
Never touch the AC plug with wet hands
Always disconnect the V1 from the power supply by pulling on the plug, not the cord.
Allow only a Doremi Labs, Inc. dealer or qualified professional engineer to repair or reassemble the V1. Apart from voiding the warranty, unqualified engineers might touch live internal parts and receive a serious electric shock
Do not put, or allow anyone to put any object, especially metal objects into the V1
Use only an AC power supply. Never use a DC power supply.
If water or any other liquid is spilled into or onto the V1, disconnect the power, and call your dealer.
Make sure the unit is well ventilated, and away from direct sunlight.
To avoid damage to internal circuitry, as well as the external finish, keep the V1 away from sources of direct heat (stoves, radiators, etc.).
Avoid using aerosol insecticides, etc. near the V1. They may damage the surface, and may ignite.
Do not use denatured alcohol, thinner or similar chemicals to clean the V1. They will damage the finish.
Modification of this equipment is dangerous, and can result in the functions of the V1 being impaired. Never attempt to modify the equipment in any way.
In order to ensure optimum performance of your V1, select the setup location carefully, and make sure the equipment is used properly. Avoid setting up the V1 in the following locations:
1. In a humid or dusty environment
2. In a room with poor ventilation
3. On a surface that is not horizontal
4. Inside a vehicle such as a car, where it will be subject to vibration
5. In an extremely hot or cold environment

1 Introduction

Thank you for your V1 purchase. The V1 is a random access video recorder that uses magnetic drives (hard drives) as a recording medium.
To record video on a hard drive it should be digitized which means that the analog video information must be converted to a digital data stream.
The V1 line of products includes uncompressed video recorders (8 and 10 bit encoding) and compressed video recorders, the trade off is between storage requirement and video quality.
Hopefully this introduction explains to the reader the basic technical principles of digital video disk recording.

1.1 V1 Uncompressed HD

The V1-UHD and V1-UHD/LE (for HDTV video) series records the video directly on the hard drive without the use of compression. The value priced V1-UHD/LE supports 8bit HD video recording only.

1.2 V1 Compressed HD: JPEG2000

Doremi’s V1-HD product line uses JPEG2000 video compression.

1.3 The CBS Algorithm

The V1 uses a constant block size (CBS) algorithm. With traditional compression algorithms, depending on video complexity, the size of each compression field can vary thus requiring maintaining a list to indicate the start of each field on the drive. With CBS all fields have the same maximum size. Consequently, CBS does not require maintaining a list indicating the start of each field because they are all the same size. This results in a more reliable video recorder with faster video access and frame accurate recording.

1.4 Audio and Time Code

In addition to the video, and regardless of the compression ratio used, the V1 records 2, 4, 6 or 8 tracks of uncompressed audio (sampled at 48Khz). It also records the LTC and digital-VITC timecodes.

2 Design of Manual

2.1 Product Series

This user manual covers the V1 JPEG2000 and Uncompressed HD series. Although the basic operation of all V1 products is the same, there are minor differences. When a feature refers to only one product series, that function will be highlighted in bold with the name of the product as seen in the examples below:
>>V1-UHD Only – for the HDTV Uncompressed product series only. If features are
supported on the V1-UHD and not on the V1-UHD/LE that will be highlighted in the text.
>>V1-HD Only – for the JPEG2000 compression product series only (V1-HD)

2.2 Firmware Versions

This manual was written with the product firmware numbers below:
HDTV Uncompressed (V1-UHD): 4.62e JPEG2000 (V1-HD): 4.62e Front Panel (RCV2) firmware 1.20
The V1 firmware can be checked by going to the OPTION MENU (hold the OPTION button then press the MENU button). Press the up or down  Menu buttons till you reach menu number 00. Press ++ until you see the version number V1 (no.).
Check the front panel firmware in the CONTROLLER MENU. Hold the ESCAPE button and press MENU. And then scroll to Firmware.
If you have a newer firmware than shown above, check the addendum pages on the back of this manual for a list of changes and additions. If you have recently upgraded your firmware please print out the README document included in the zip file with the new firmware. You can also download the latest V1 manual from our tech support page “manual” section on the Doremi website
www.doremilabs.com.
If you will not be upgrading, you can download older manuals from the Doremi FTP page.

2.3 Menu Customs

CAPITAL & BOLD text is used when referring to buttons on the front panel.
Menu (no.) text provides the MENU, OPTION MENU, or CONTROLLER MENU name and the menu function #.

5 Product Description

5.1 Overview: V1-HD vs V1-UHD

Figure 15: V1-UHD and V1-UHD/LE Overview
The V1-UHD offers the superior resolution of high definition video in a compact full featured disk recorder. Instant access to video, uncompressed recording and networkable operation make the V1­UHD the ideal multi-format recorder. The V1-UHD is only three rack units high and is available with fixed or hot swappable internal drives. An external RAID5 chassis is also available.
The V1-UHD records high definition serial digital video (HD-SDI) and standard definition SDI video. Frame accurate control via RS-422 makes the V1-UHD a drop-in replacement for any HD video tape recorder. The available Gigabit Ethernet interface is ideal for fast network transfer of still image and movie files to/form graphics and editing workstations.
The V1-UHD/LE is a value version of the V1-UHD with two removable hot-swap drives. The V1­UHD/LE only supports 8bit HD-SDI recording. SD video can be recorded at 10bit or 8bit.
Figure 16: V1-HD Overview
Doremi's V1-HD server sets the standard for affordable high-performance HD video recording. The V1-HD records HD-SDI and SDI video using JPEG2000 compression at up to 300Mb/s.
For digital cinema applications, the V1-HD is available with dual link 4:4:4 recording and playback at 2K resolution. Dual-synchronized playback is supported for video+key, super-widescreen and 3D applications.

5.2.4 LCD Time Code Display

Figure 20: LCD Time Code Display
The First line of the display shows the following:
Time location of the video material using the following format: “HH:MM:SS:FF F1/F2” "HH" represent the hours from 00 to 23, "MM" represent the minutes from 00 to 59, "SS"
represents the seconds from 00 to 59, "FF" represents the frames from 00 to 24 in PAL frame-rates, 00 to 29 in NTSC frame-rates and 00 to 23 in 24P-48i frame-rates - "F1/F2" represent the field: "F1" for odd fields and "F2" for even fields.
This display shows the Time Code depending upon what the user has selected in MENU (2)
Time Mode. The display also shows Drop/NonDrop information; “.” Means NonDrop and “;”
means DROP frame. Field one shows “.” Field two shows “:” or “;”
The Second line displays the following:
At the V1 start-up, the bottom left displays the firmware version of the V1, then No Disk and
Scanning messages will alternate on the left side, then No MD Found and Scanning
messages will alternate once a disk is detected and Stop is displayed on the right side until a valid drive is recognized on the SCSI bus of the V1, in such case No Disk, No MD Found will disappear and only Stop will be displayed indicating that the V1 is now ready to access the drive. If No Disk/Scanning is still displayed even though a disk was installed, the V1 did not recognize the disk. If No MD Found / Scanning is still displayed, it is an indication that
the V1 has detected a disk but it cannot be mounted – refer to paragraph 14.7 for details.
During transport controls, the current operation is shown on the right side of the display:
Servo-Lock Dot, PLAY, STOP, REWIND, FORWARD, RECORD, JOG, SHUTTLE, VAR.
"VAR" is indicated during play in chase on LTC/MTC or in variable speed from RS422.

If forward shuttle: ">> xx %" with xx % = 10%, 20%, 48%, 100%, 200%, 500%, 1000% If reverse shuttle: "<< xx %" with xx % = 10%, 20%, 48%, 100%, 200%, 500%, 1000%
During segment playback, the remaining time up to the OUT point is shown as "no. :
MM.SS", where "no." is the number of the segment played from 001 to 2047, "MM.SS" is
the remaining time up to the OUT point of the segment played in mn:sec
