The DVxplore鈩?codec from C-Cube Microsystems is the indus-
try鈥檚 first single-chip MPEG-2 and DV consumer codec, deliver-
ing DVD-quality video recording and playback for consumer
applications. The DVxplore codec enables exciting new content
creation and PC/TV applications for the home, based on DVD-
quality video recording.
For the first time, PC manufacturers can offer consumers
DVD-quality video recording and frame-accurate MPEG-2
editing, turning PCs into complete DVD recording and content
creation stations. Manufacturers can incorporate sophisticated
digital video recording features, such as automatic television
program recording using an electronic program guide (EPG),
into consumer PC/TV products. Digital recorder applications
can provide time-shifting capabilities such as instant replays
of broadcast programs. As a result, manufacturers and applica-
tions developers can use the codec to establish DVD-quality
(MPEG-2) video as a standard data type on consumer PC and
PC/TV platforms.
The DVxplore codec leverages C-Cube鈥檚 highly flexible DVx video
compression and decompression architecture to provide an
unprecedented range of capabilities that aren鈥檛 limited to a single
video format. PC users can acquire video from analog, DV, or
MPEG sources and edit it with frame accuracy to create MPEG-2
videos that play back on any MPEG-2 or DVD decoder. Employ-
ing MPEG-2 compression, users can extend recording time tenfold compared to Motion JPEG (M-JPEG) or DV
solutions. They can also use the codec to address low-bandwidth applications such as MPEG-1 video for websites
and email.

The versatile DVxplore codec provides these six key functions:
鈥?/div>
MPEG-2 Encoding:
PCs can record DVD-quality video using C-Cube鈥檚 advanced, highly reliable PerfectView鈩?/div>
encoding algorithm.
鈥?/div>
Dual-Stream MPEG-2 Decoding:
Two MPEG-2 data streams can be decoded simultaneously to provide frame-
accurate editing of MPEG-2 video. Hardware rendering of special effects (fades, wipes, or dissolves) enables real-
time preview of the edited video.
鈥?/div>
Realtime DV to MPEG-2 Transcoding:
Users can convert digital video from consumer DV camcorders to MPEG-2
video, enabling playback on any MPEG-2 or DVD decoder. The all digital conversion process delivers DVD qual-
ity while minimizing the storage requirements for captured video.
