New groups – Innovations Group
• JPEG Innovations formed to increase
awareness of JPEG family of standards, to
identify, explore and investigate new image
related standard topics, to engage with
industry and academia to hold workshops and
seminars on these areas and raise the
momentum for starting new standardization
work items.
• AHG meeting report WG1N5405
AIC
• standardization of a new evaluation approach
and image compression system for any potential
technologies can be identified which significantly
would improve the current image coding
standard
• AIC ad hoc group is pleased to announce the
production of calls for technologies, use cases,
requirement, evaluation procedures and test
material for three targeted applications: medical
imaging, camera sensors imaging and security
applications
Progression at 51st meeting
• updated call for Advanced Image Coding of Medical
Imaging in WG1N5386 (LS to DICOM, in WG1N5389)
• updated call for Call for Medical image databases in
WG1N5404 (LS to DICOM, in WG1N5392)
• Call for AIC of Camera Sensor Data in WG1N5387 (also
LS to ISO TC42, WG1N5390)
• Call for AIC for security applications in WG1N5388 (LS
to ISO TC223 WG 5, in WG1N5391)
• and invites National Bodies and delegates to provide
comments and feedback, and to distribute it through
appropriate channels.
N5388 CfP security applications
• An area of special interest is the creation of
new image coding scheme for security
applications such as video-surveillance,
forensics, biometrics, unattended cameras, …
Mandatory features of the candidate
technologies are as follows:
• Support QCIF to Ultra HD resolution, including various aspect ratios.
• Support of still and moving pictures.
• Support for high sample precision integer data, sample resolutions of
8bpp to 16bpp per component.
• Rate/distortion performance at least as good as MPEG-4 AVC/H.264 and
JPEG 2000 standards.
• Progressive image mode only.
• Support for gray-scale, color and multispectral sample data.
• Embedding of lower quality, lower resolution images for rendering and
preview purposes.
• Very low to medium complexity compared to existing standards and
potentially adapted to parallel architectures.
• Support for compression factors up to visually lossless.
• Region of interest or random access to the bitstream for partial decoding.
Additional features that are desired:
• Error/loss protection and error/loss resilience features to ensure the
suitability for exchange over a variety of error prone channels as well as
long-term storage.
• Support the reusability of intermediate coding results for external video
analysis/processing.
• Ability to annotate the image data by suitable metadata
• Support of computational complexity scalability at the encoder and the
decoder.
• Support of lossless compression.
• Support of stereoscopic and multi-view sources
• Backwards compatibility to existing formats.
• Support of spatial and quality scalability.
• Handling of HDR sensors data.
• Embedded security (watermarking, fingerprinting, steganography,
bitstream selective encryption, …)
• Conditional access, data integrity and privacy protection.
N5387 CfP Camera sensor data
• An area of special interest is the creation of
archival and interchange formats for unprocessed
camera (“raw”) data, however interested parties
should be aware that AIC is also interested in
other coding and specifically evaluation
technologies that are described in other calls.
• Proposed technologies will be evaluated under a
uniformly-acceptable testing setup and
considered for standardization if appropriate.
Most desirable features of the
candidate technologies are as follows:
• Ability to represent sensor data from a wide variety of existing and
expected solutions in the market (Bayer pattern and other types of
sensors).
• Lossless compression of such data.
• Constrained lossy compression, limiting the maximal tolerable
distortion defined by a well-accepted quality threshold of the
demosaiced image.
• Embedding of lower quality, lower resolution images for rendering
and preview purposes by a simplified demosaicing.
• Low complexity adapted to parallel architectures.
• Ability to annotate the image data by suitable metadata including,
but not limited to color spaces, camera settings, optical and sensor
characteristics, …
Additional features that could be
considered:
• Backwards compatibility to existing formats and
solutions.
• Spatial and quality scalability.
• Relationship to, or inclusion of, demosaicing tools and
techniques.
• Storage of HDR sensors data.
• Conditional access, data integrity and rights protection.
• Error/loss protection and error/loss resilience features
to ensure the suitability for exchange over a variety of
error prone channels as well as long-term storage.
Ongoing work
• amendment on guidelines for Digital Cinema enables
the determination of the data size of the compressed
bit stream from the predefined bit rate and allows a
wider range of frame rates.
• all four parts of the JPEG XR image coding system
completed
• ISO/IEC 24800 JPSearch, Part 2, Registration,
identification, and management of schema and
ontology, and Part 4, File format for metadata
embedded in image data at FDIS; Part 5, Data
interchange format between image repositories at FCD

N 11221 Possible future actions on
standardization with Type 1 licensing
• At the Kyoto meeting China stated a development team had
developed an open source video codec with performance
close to MPEG-2 without adopting the patents in MPEG-2
or subsequent standards
• Some NBs not convinced there is a need for the activity,
others want to explore the possibility
• IETF starting work on a royalty-free audio codec and W3C is
planning to standardise audio and video tags for royalty fee
free codecs.
• ISO/IEC cannot guarantee royalty-free or even RAND
terms. But MPEG standards will become royalty-free
eventually, e.g. a royalty-free MPEG-2 profile could be
created after most of the essential patents expire in 2014.
Dresden Resolution 10.4.1
• Given that there is a desire for using royalty free video coding
technologies for some applications such as video distribution
over the Internet, MPEG wishes to enquire of National Bodies
about their willingness to commit to active participation (as
defined by Section 6.2.1.4 of the JTC1 directives) in
developing a Type-1 video coding standard. MPEG would
appreciate if NBs provide the names of individual
organisations that will commit resources. MPEG will use the
information gathered from the NB responses, particularly
including the number of countries willing to actively
participate, in order to decide at the Geneva meeting whether
to request approval of a new Work Item Proposal. MPEG does
not intend to reopen the issue, unless strong support of at
least five national bodies is presented in the future
Advanced IPTV Terminal timeline
• Publication of Call for Proposals: January 2010
• Publication of 2nd Call for Proposals: April 2010
• All parties that believe they have relevant
technologies for AIT are invited to submit these
technologies for consideration by MPEG and
Q.13/16
• Submission and study of responses: July 2010
• Development of the AIT standard: July 2010 - July
2011
• Approval of the AIT standard (FDIS): July 2011
11336 2nd Joint Call for Proposals on
Advanced IPTV Terminal
• The purpose of the AIT standard is to leverage on advanced technologies
to bring into IPTV services exciting initiatives with new features such as
open APIs and the possibility for third parties to provide applications to
those APIs.
• Both MPEG and Question 13 of ITU-T SG16 (Q.13/16) feel that, by
standardizing a flexible set of protocols and interfaces, it will enable
“media service ecosystems” yielding new forms of advanced digital media
services capable of innovating the IPTV landscape.
• Such a set of protocols and interfaces is the target of the Advanced IPTV
Terminal standard that MPEG and ITU-T Question 13, “Multimedia
Platforms and End-Systems for IPTV Services”, of Study Group16 (Q.13/16)
plan to develop jointly for IPTV terminals more advanced (in terms of
functionalities) than the current IPTV terminals standardized or being
standardized by ITU-T.
• AIT will support the service providers’ drive to deploy innovative
multimedia services by identifying a set of “Elementary Services” and
defining the corresponding set of protocols and APIs to enable any user in
an AIT value chain to access those services in an interoperable fashion.
•
Note that an AIT value chain is a collection of Users, including Creators, End Users
and Service Providers, that conforms to the AIT standard.
AIT Ecosystem: AIT standard-enabled digital media
service eco-system underpinning and supporting
the activities of content creators and consumers
Minimal Complexity Video Coding
• Resolution 10.2.1
• The requirements group recommends that members
consider document m17005 and bring technical
contributions on “minimal complexity video coding” to
the 93rd meeting.
• M17005 proposes the development of a lightweight
compressor of progressively scanned video, with 7
identified characteristics such as
– achieves the same or better compression as the
combination of interlace (2:1) and chroma subsampling
– is simple enough to implement in or near a camera sensor,
or display
– handles bit-depths greater than 8 bits per pixel
– able to achieve a fixed compression ratio
MMT: MPEG Media Transport
• MMT is intended to provide adaptive progressive
transport with cross layer optimization, suitable for
both hybrid delivery and conversational services.
• There has been interest from 3GPP and OIPF.
• MMT Workshop had been held during recent MPEG
meetings (London, Kyoto)
• Not yet a single view on the requirements, and a target
architecture still needs to be agreed.
• A CfP on MMT was to be published in April 2010, with
response due in July 2010 but with disruption to travel
the call was split and only the first part CfP on HTTPbased streaming using MP4 and MPEG2/TS files was
finalised and issued.
