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.

6. 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, …

7. 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.

8. 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.

9. 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.

10. 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, …

20. 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.

21. 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

22. 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

23. 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.

24. AIT Ecosystem: AIT standard-enabled digital media service eco-system underpinning and supporting the activities of content creators and consumers

25. 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

26. 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 HTTP-based streaming using MP4 and MPEG2/TS fileswas finalised and issued.
