OVERVIEW
Q HD DVR
CIRCUIT BOARD
Overview
The Q HD is a board level high definition digital video recorder based on J2K compression. With
its broadcast level image quality and near lossless J2K compression, it is ideal for high definition
recording applications that demand only the very best image quality including: high end
surveillance, law enforcement, military and medical.
Q HD is designed with the same cutting-edge digital video recorder technology used in the
Omega HD. It provides outstanding image quality at 1080i, 720p and 480i, records at data rates
up to 100Mbits/s, offers 4:2:2 sampling and a full 10 bit quantization.
High definition recordings are full resolution - 1920 x 1080 (1080i) or 1280 x 720 (720p),
regardless of the compression level used.
With HD-SDI and SD-SDI I/O capabilities the Q HD also features RS-422 control using Sony,
Odetics and FFV serial protocol and an extensive menu of control and configuration options. Q
HD is versatile enough to satisfy a variety of demanding DVR applications.
Configuration
Prior to use, set the configuration to verify operation as expected. Specific settings that should be
checked:
Resolution: 1080i, 720p or 480i; and frame rate: 59.94, and 50.
Disk Format: MOE (Fast Forward Proprietary) or FAT32
File Format: MOE (Fast Forward Proprietary) or QuickTime
Following any change in the Disk or File formats:
“Delete All Video” to prepare the disk for recording.
Other settings as shown in the Serial Control Protocol Document, Section 3.1. The
document, serialxx.pdf, is available from the Technical Support page of www.ffv.com.

ARCHITECTURE
Q HD DVR
CIRCUIT BOARD
Architecture
The Q HD DVR’s primary design goal was to maintain video quality at a level suitable for use in
professional video applications. Since image quality is of utmost importance, JPEG2000
compression is used to provide the highest picture quality.
To support a sustained data rate at this level, the designers of the Q HD DVR included a SATA
hard disk controller on the circuit board.
The design includes an on-board ARM processor to oversee the hardware and to provide a
control interface through the serial ports.
All of the Q HD DVR’s subsystems share thirty-two (32) megabytes of dynamic random access
memory. This memory is based on a true multi-port architecture that allows direct access by the
JPEG codec, the disk controller, and the local ARM processor. Direct access to this memory
permits each of the subsystems to perform to their maximum potential without concern for DMA
contention.
Following is a block diagram of the Q HD DVR.

Incoming LTC data is loaded into the receive buffer following the receipt of a valid LTC SYNC pattern.
* SMPTE SYNC Sources - A time code generator must have a SYNC input from a stable source in
order to position the LTC code properly on an audio track of video tape or film. Two SYNC sources, click
input, and free running, are available. If some external SYNC source is available it can be input on the
CLICK input. Otherwise, a free running SMPTE SYNC is generated from the oscillator at the selected
frame rate.
