Chapter 1 - Introduction
letterbox aspect ratios. This makes the camcorder ideal for multi-format acquisition and for
straightforward migration from standard definition (SD) to high definition (HD) within your
workflow. The camcorder provides digital imaging for crystal-clear quality with advanced 22-bit
accurate video processing for image control.
1.1.3 IT-based recording media
The Infinity Digital Media Camcorder is the first camcorder to use off-the-shelf REV PRO
removable disks and professional-grade CompactFlash solid-state memory as recording and
playback media. The extremely durable REV PRO removable disks provide the portability, and
cost-effectiveness of videotape with the speed, flexibility, and ease-of-use of true nonlinear
media such as hard disks.
Professional-grade CompactFlash memory is a readily available solid-state technology that
delivers the high level of performance needed for demanding professional video applications.
These cards are small, lightweight and extremely durable. Professional-grade CompactFlash
cards currently hold up to 16 GB with sufficient throughput for both SD and HD recording.
Trends indicate that CompactFlash cards will continue to increase in storage capacity while
decreasing in cost—making it an excellent open solution for solid-state recording.
Both REV PRO and CompactFlash media offer unprecedented advantages in terms of usability,
price and performance. They offer many benefits for video professionals such as nonlinear
random access to video files, simultaneous playback while recording and non-degrading
archival storage.
1.1.4 On-board selectable compression
Infinity Series products provide you a choice of compression schemes and bit rates, giving you
the option to select what is best for your workflow today and for the future. The Infinity Digital
Media Camcorder supports DV, JPEG2000 and MPEG-2 (optional) compression, assignable via
the camcorder’s user interface. The DV codec is 25 Mb/s 4:2:0 (PAL) or 4:1:1 (NTSC), making it
ideal for immediate use in your workflow today. JPEG2000 is a next-generation compression
scheme that can be used for both SD and HD acquisition. It provides high-efficiency
compression, 10-bit 4:2:2 encoding, high image quality and no blocking artifacts —and is fully
scalable. Industry-standard MPEG-2 compression is available as an option and can be used for
a variety of HD compression profiles.
1.1.5 Ultimate connectivity
The Infinity Digital Media Camcorder connects using both traditional and IT interfaces.
Traditional inputs and outputs include BNC connectors for (HD-)SDI, CVBS, Time Code, AES
digital audio and XLRs for analog audio. The camcorder comes with three USB 2.0 connectors
(two hosts and one device), one IEEE 1394 connector and a HDMI display connector. It can
also connect to an external storage device (such as a hard drive or flash memory stick) via USB
or IEEE 1394. The Gigabit Ethernet port provides access to Ethernet networks.
