Digital Video Server

The UltraNEXUS is equipped with a built-in, multi-channel digital video server
that includes two fully independent digital video playback (decode) channels and
dual digital record (encode) channels. Every time you record, the dual recorders
create two files of identical content—one for broadcast, one for the Web.
For television broadcasting, the primary record channel may be configured to
capture high-quality MPEG-2 files. Three user-defined recording parameters
allow the operator to select constant (CBR) or variable (VBR) bit rate encoding,
target video bit rate(s), full D1 or half D1 resolution, and audio sampling settings.
For immediate or scheduled recording, simply click on one of the three recording
presets to select the right parameters for the job.
The VOD recorder automatically creates files using a minimized data bit rate
and resolution suitable for Web applications. VOD files may be automatically
transferred to a specific PEG Central account, simplifying the often difficult task
of creating Web suitable media from digital television files.
Automated Ingest
A special ingest feature included with the UltraNEXUS uses PRO-BUS control
to automate recording from videotape and DVD source machines. Select the
source device from any of the system resources, indicate the desired quality
using the recording presets, name your file, enter the length, and go. WinLGX
software automates the process and allows you to digitize your video with ease.
File Transfer
If your programming originates from a source outside your playback system,
such as output from a non-linear editor, simply transfer the files onto the
UltraNEXUS hard drive for immediate playback. The UltraNEXUS accepts
MPEG-1 and MPEG-2 files output from many popular non-linear editing systems
and professional encoding equipment. Gigabit Ethernet ensures rapid transfers
of large media files.
Scalable Local Media Storage
For an innovative approach to media storage, the UltraNEXUS uses external
hard drives connected to USB (Universal Serial Bus) ports. The UltraNEXUS
digital media storage is fully scalable, with four USB 2.0 ports that allow you to
set up and adjust your file storage capacity to meet the specific needs of your
operation. Connect up to a total of four terabytes of external USB storage to
hold hundreds of hours of programming. The UltraNEXUS even supports USB
drive configurations with RAID protection. With increased drive capacity and
lower cost, USB storage makes sense and saves you money.
Note: For automatic transfer of broadcast media files to a NEXUS/UltraNEXUS
or other FTP destination, a minimum of one USB drive is required. For VOD
encoding and automatic transfer of media files to PEG Central, Schoolstream.
tv, or Worshipnet.TV, a minimum of two USB drives are required. USB storage
devices sold separately.
