remote control, or other devices per a system's needs.
DIGITAL FRONT-END ARCHITECTURE
The Vaddis 6 includes fully-digital front-end processing. The main
components of this front-end are the read-channel for data retrieval
(through an RF amplifier) from the optical pick-up unit (OPU) and the
servo, which enables precise tracking of the optical media. This
architecture allows for flexibility in choice of OPU's and mechanisms.
It also allows for high performance in error handling of scratched and
fingerprinted media.
MULTI-FUNCTION PLAYER
The Vaddis 6 contains the video and audio processing power to
handle playback of all of the disc types listed in "Features". The
Vaddis 6 is designed with Zoran's StandardsPlusTM methodology,
which means that the device is capable of supporting existing stan-
dards with some desirable enhancements including HDCDTM, MP3,
JPEG and WMA file playback. The programmable nature of the
Vaddis 6 makes it ready for future standards and enhancements.
Features Description
STREAM PARSING
The Vaddis 6 can process disc sectors of the disc types listed previ-
ously. The bitstreams from these sectors are typically separated into
video and audio for further processing, although other data types can
be supported (e.g. VMGI, VTSI, sub-pictures). Included in this pars-
ing is any necessary authentication and decryption (e.g. CSS,
CPPM, CPRM) for DVD-Video, DVD-RW or DVD+RW.
VIDEO DECODING
The Vaddis 6 supports video decoding of the various MPEG for-
mats and picture sizes supported by DVD, SuperVCD, CVD,
VideoCD and DVCD. Frame rates and sizes can be converted
DataShebeett4wUee.cnoNmTSC and PAL. JPEG decoding is supported for PictureCD
viewing and JPEG file viewing.
AUDIO DECODING
The Vaddis 6 includes a 67 MIPS audio decode processor (ADP)
capable of supporting the latest advanced audio algorithms including
Dolby Digital, DTS, MPEG Layer II, LPCM, CD-DA, MP3 and WMA.
ZORANZOOM AND IMAGE ENHANCEMENT FILTERS
The Vaddis 6 incorporates ZoranZoom, Zoran’s proprietary scaling
algorithm and several filtering functions for enhancing the image
quality. ZoranZoom is the built-in zoom and pan function which pro-
vides a crisp image for the resulting enlarged view. The Vaddis 6
supports user picture controls including sharpness (edge enhance-
ment), and brightness adjustments for optimizing the image quality.
