Digital Media Systems
North Valley Research is pleased to announce immediate availability of
a family of products for working with video and other time-based media
in a UNIX environment. These products are the first, affordable software
products that enable the end user to take video and audio all the way
from video camera or tape to an MPEG sequence that can be played back in
real-time on most Sun SPARCstations. Starting now until May 5th, 1993,
individual products can be purchased for $150 in quantities of 30 or
more; or under $300 for quantity 1.
These software products have well-designed Motif user interfaces and a
robust architectural design. The first set of products is sold as a kit, and
consists of three user interfaces:
- The Player. This tool provides a viewing mechanism for working with
+ MPEG sequences
+ analog video (requires the Parallax XVideo board)
+ JPEG movies (requires the Parallax XVideo board with JPEG option)
- The Recorder. This tool enables the user to peruse analog material
with an interface very similar to the Player, but in addition, allows
you to create JPEG movies using the JPEG hardware on the Parallax XVideo
- The Compressor. This tool allows you to choose input files, specify
the compression characteristics and finally, compress them with
our software MPEG compression engine.
The MPEG playback mechanism is purely software, requires no special
framebuffer, and depending on the size of picture, the size of the window
and bandwidth of the bitstream, can run at 6 - 30 fps with synchronized
audio. The color is dithered from 19 bits down to 7 bits,
gamma-corrected, with real-time adjustments for contrast and brightness.
The displayed window can be one or four times the size of the MPEG sequence
picture size. For example, a sequence compressed at 320x240 can be played
back at 320x240 or 640x480 (depending on the performance of the host
Both the MPEG compression and playback mechanisms support:
+ variable I:P:B ratios
+ variable picture sizes from 64x48 to 320x240
+ variable and fixed bit rate
+ three motion estimation algorithms (Jain & Jain and two Exhaustive methods)
The MPEG compressor is relatively fast for compression that includes motion
estimation, and depending on the input stream and the selected compression
parameters, can compress a twenty second sequence in as little as an hour.
The JPEG record and playback is accomplished with the aid of the Parallax
XVideo board. Recording and playback of JPEG movies is controlled by
a special software engine that always keeps the audio and video synchronized.
Recorded sequences may be "running records" from a camera or broadcast, or
assembled from a controllable video source with in and out points.
Both the Player and Recorder support Sony's ViSCA/LANC, and Pioneer 4400
disc players (and other compatible models). VideoMedia's VLAN will be
added in the future.
