GENERAL DESCRIPTION
The ADV202 is a single-chip JPEG2000 codec targeted for
video and high bandwidth image compression applications that
can benefit from the enhanced quality and feature set provided
by the JPEG2000 (J2K)—ISO/IEC15444-1 image compression
standard. The part implements the computationally intensive
operations of the JPEG2000 image compression standard as well
as providing fully compliant code-stream generation for most
applications.
The ADV202’s dedicated video port provides glueless connection
to common digital video standards such as ITU.R-BT656,
SMPTE125M, SMPTE293M (525p), ITU.R-BT1358 (625p),
SMPTE274M (1080i), or SMPTE296M (720p). A variety of other
high speed, synchronous pixel and video formats can also be sup-
ported using the programmable framing and validation signals.

ADV202
GENERAL DESCRIPTION
(continued from Page 1)
The ADV202 can process images at a rate of 40 MSPS in
reversible mode and at higher rates when used in irreversible
mode. The ADV202 contains a dedicated wavelet transform
engine, three entropy codecs, an on-board memory system, and
an embedded RISC processor that can provide a complete
JPEG2000 compression/decompression solution.
The wavelet processor supports the 9/7 irreversible wavelet
transform and the 5/3 wavelet transform in reversible and
irreversible modes. The entropy codecs support all features in
the JPEG2000 Part 1 specification, except Maxshift ROI.
The ADV202 operates on a rectangular array of pixel samples
called a tile. A tile can contain a complete image, up to the
maximum supported size, or some portion of an image. The
maximum horizontal tile size supported depends on the wavelet
transform selected and the number of samples in the tile.
Images larger than the ADV202’s maximum tile size can be
broken into individual tiles and then sent sequentially to the
chip while still maintaining a single, fully compliant JPEG2000
code stream for the entire image.
Data Sheet
JPEG2000 FEATURE SUPPORT
The ADV202 supports a broad set of features that are included
in Part 1 of the JPEG2000 standard (ISO/IEC 15444). See
Getting Started with ADV202 for information on the JPEG2000
features that the ADV202 currently supports.
Depending on the particular application requirements, the
ADV202 can provide varying levels of JPEG2000 compression
support. It can provide raw code-block and attribute data
output, which allow the host software to have complete control
over the generation of the JPEG2000 code stream and other
aspects of the compression process such as bit-rate control.
Otherwise, the ADV202 can create a complete, fully compliant
JPEG2000 code stream (.j2c) and enhanced file formats such as
.jp2 and .j2c. See Getting Started with ADV202 for information
on the formats that the ADV202 currently supports.
