[opendtv] PR: Analog Devices' JPEG2000 IC Enables Wireless High-Definition Video Distribution in the Home

The wavelets are coming...the wavelets are coming...

More than a decade ago wavelets looked like a contender for  a 
variety of digital video compression applications. Aware designed a 
wavelet processor chip used by Immix in their TurboCube non-linear 
video editing system. Eventually Aware was acquired by Analog 
Devices, and Immix was acquired by Scitex Digital Video. Along the 
way Scitex abandoned wavelets and got on the Motion-JPEG bandwagon.

Isn't it ironic...

The world on non-linear editing was built atop a compression 
technology designed for still image. Granted, JPEG and MPEG shared 
the same DCT-based image transform that is used both for I frames 
(and still images); MPEG went a step further with Interframe 
compression, including P and B frames. But frame based compression 
systems were exactly what was needed to launch the non-linear market, 
and JPEG processing chips stepped up to meet the commercial 
opportunity.

A decade later, the experts in JPEG have abandoned the DCT transform 
in favor of wavelets, which form the basis for the JPEG-2000 
standard. For those of us with experience in these matters, you could 
see another transformation in the works. With the commercialization 
of JPEG-2000 chips, it would only be a matter of time before wavelets 
started to invade the turf of MPEG and the world of non-linear 
editing. Looks like Analog devices is fiinally going to see a real 
commercial market for its wavelet processor chips...

2005 DisplaySearch HDTV Conference  LOS ANGELES--(BUSINESS 
WIRE)--Aug. 22, 2005--

- ADI and Pulse-LINK demonstrate industry's first solution for 
real-time HD wireless video transmission suitable for wireless gaming 
applications and digital video recorders.

Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance 
semiconductors for signal processing applications, today announced 
that it will demonstrate the first real-time compression and wireless 
transmission of high-definition (HD) video in a consumer application 
at the DisplaySearch HDTV Conference on August 23-24, 2005.

The combination of Ultra Wideband (UWB) technology from Pulse-LINK, a 
leading developer of UWB communications systems 
(http://www.pulselink.net), and Analog Devices' ADV202, the only 
real-time HD implementation of the JPEG2000 standard, drastically 
reduces the visual impact of errors that occur in wireless 
transmission channels, producing good image quality even in noisy 
environments. While other encoder technology has proven expensive and 
unable to achieve practical real-time HD video compression, JPEG2000 
enables high-quality, low-latency wireless HD gaming applications, 
and high-quality, low-cost wireless HD or SD (standard definition) 
video distribution in the home.

In addition to the ADV202 compression engine for handling the HD 
signal, the solution includes Pulse-LINK's Continuous Wave 
(CWave(TM)) UWB architecture, which forms the foundation of a 1Gbps 
UWB radio. CWave differs from other UWB technology in that its signal 
derives from a narrowband frequency that is modulated to create a UWB 
signal spectrum.

"Pulse-LINK's CWave(TM) UWB technology combined with Analog Devices 
JPEG2000 codec solves many of the challenges associated with 
implementing QoS for streaming HDTV wirelessly," said John Santhoff, 
Chief Technology Officer, Pulse-LINK. "Together, these technologies 
produce a low-latency, highly responsive interactive video gaming 
experience wirelessly as well as the first lossless wireless 
alternative to DVI and HDMI."

"Analog Devices is no stranger to developing high-performance 
components for advanced TV applications, including those in the 
ever-expanding HD market," said Bill Bucklen, product line director, 
high-speed converters, Analog Devices. "We are pleased to team with 
Pulse-LINK to deliver a wireless HD solution that makes wireless 
distribution of professional quality video available to the consumer 
electronics market."

About the JPEG2000 Standard

JPEG2000, which was established as an international standard in 
January 2001, is an image compression standard based on wavelet 
transforms. The wavelet transform is a technology that applies 
two-dimensional filtering and sub-sampling (pixel decimation) in 
hierarchical and multi-step combinations.

JPEG2000 compresses each frame independently, so that transmission 
errors affect only a single frame, and do not propagate through 
subsequent images. Because there is no inter-frame processing, 
end-to-end latency is very low. This is important in many 
applications, like wireless gaming, where the character on the 
display needs to react as soon as the controller is moved, something 
that cannot be accomplished with other compression standards. 
Competing compression solutions, such as MPEG-2 and other 
temporal-based schemes, compress multiple frames as a group - a 
single transmission error can often affect most of the frames in that 
group, resulting in a very disturbing disruption of the video. 
JPEG2000 also enables the compression of HD video in real-time at 
consumer price points, a fraction of the cost of other techniques.

Real-time compression and decompression of high-quality images

ADI's JPEG2000 solutions allow the extraction, compression and 
transmission of video images at varying resolutions without further 
signal processing. The JPEG2000 solution features ADI's SURF(TM) 
(spatial ultra-efficient recursive filtering) wavelet technology, 
enabling real-time compression and resolution scalability. This is 
particularly interesting in the HD market because HD content can be 
compressed once, and decompressed by multiple displays of various 
resolutions. For instance, the same video source can transmit a 
single stream that can be received and displayed by an HDTV, an SDTV 
and a PDA simultaneously, and each device may process only the 
information it requires.

Stored, compressed video can also be reduced in size, without 
decoding, by deleting some of the stored data - all frames are still 
represented, but at a lower level of quality than the original. This 
is attractive in DVR applications, where programs can be initially 
recorded at the highest quality, but later reduced in size to free up 
disk space for more compressed content. Currently, the only HD-DVRs 
available are those that are built into a set-top box product and 
record precompressed video streams, since real-time HD video 
compression using traditional techniques is impractical in the home. 
The ADV202 offers a low-cost solution that can compress the HD video 
inputs from any source in real-time with extremely high playback 
quality, and provide very flexible recording capabilities.

The unique wavelet-based codestream also supports selective 
protection of packets. In the event that the channel becomes so noisy 
that some packet errors cannot be corrected, the video quality 
degrades gracefully. An MPEG-2 or other temporally-compressed video 
stream is considered by most audiences to be visually unacceptable in 
noisy channel conditions.

The ADV202 JPEG2000 IC

The ADV202 comes in a compact 12mm x 12mm BGA package and is 
available now in production quantities. Widely used in professional 
video and digital cinema applications, the ADV202 can be used 
immediately for cutting-edge video solutions and is the basis for 
future low-cost versions suitable for consumer electronics. For more
