DVD Decoding
: Hardware DVD video decoding provides
the highest video quality with minimal host CPU
requirements. The DVxplore codec performs full decod-
ing of CSS-encrypted MPEG-2 video and subpicture
streams.
MPEG-1 Encoding
: Users can take advantage of MPEG-1
video capture for low-bandwidth Internet and intranet
video applications such as live “webcams,” video clips on
websites, and video email attachments.
Single Stream DV Codec
: The DVxplore codec also
allows users to capture and edit video in native DV
format.

The DVxplore codec delivers MPEG-2 video to consumer
PCs, allowing full-screen DVD-quality video recording and
playback at consumer prices. The codec runs downloadable
microcode that lets it operate as both a DVD-quality digital
video recorder (encoding) and player (decoding). C-Cube’s
patented PerfectView encoding algorithm produces superior
images using a number of techniques—including multilayer
motion estimation, variable bit-rate encoding, inverse
telecine, and optimal bit allocation—that work together to
improve encoding efficiency and picture quality.
In conjunction with a software AC-3 decoder running on
the host processor, The DVxplore codec provides C-Cube’s
market-tested DVD playback feature set: MPEG-2 decod-
ing, subpicture decoding, PCM audio, A/ V synchronization,
and SecureView CSS copy protection.

DITING
With the DVxplore codec, personal video content creators
get WYSIWYG (“what you see is what you get”) simplicity.
Hardware acceleration for dual-stream decoding and video
postprocessing lets users perform seamless MPEG editing
in realtime using C-Cube’s revolutionary FAME (Frame
Accurate MPEG Editing) technology. FAME allows users to
implement special effects on the fly, and accomplish A/ B
roll transitions across frames such as fades and dissolves.
Because the DVxplore codec records and edits the video in
MPEG-2 format, all files can easily be stored on an ATAPI
hard disk.

RANSCODING
The DVxplore codec is a forward-looking solution that
supports DV-format digital camcorders as well as conven-
tional analog camcorders. This feature is especially desir-
able as consumers increasingly turn to digital video
cameras and consumer PCs come equipped with an IEEE
1394 “Firewire” interface. The DV to MPEG-2 transcoding
capability creates video files that are playable on any
MPEG-2 or DVD decoder. Transcoding also saves disk
space by increasing compression 5 to 10 times.
