New release of H.264/AVC reference software JM 17.1

-- this blog post is based on the email sent by Karsten Sühring to the JVT reflector

A new release of the JM reference software is available at http://iphome.hhi.de/suehring/tml/

This is a quite large maintenance release: It contains a number of bug fixes including a decoder issue that was introduced in JM 17.0 and caused a mismatch for MBAff and constrained intra prediction.

The documentation has been updated with a description of the new MVC coding mode. Many people experienced crashes when enabling MVC with the default config file. This was caused by an incompatible setting which is now prohibited for the muti-view encoding mode. We have also added a Stereo High profile example config (encoder_stereo.cfg) and a modified default file for faster encoding (encoder_fast.cfg).

The VS 2008 and XCode workspaces have been updated for better x64 architecture support. OPENMP (for parallel deblocking) is now enabled by default (also in the Makefiles).

-------------------------------------------------------------------------
Changes in Version JM 17.1 (since JM 17.0)
-------------------------------------------------------------------------
- decoder: fix delta_pic_order_cnt[0] in IDR frames (KS, bug #57)
- decoder: Direct mode fixes (YHE)
- encoder/decoder: various cleanups and bug fixes (AT/YHE)
- encoder/decoder: rewrite of deblocking functions (AT)
- decoder : rewrite of intra prediction functions (AT)
- encoder/decoder: MVC bug fixes (PeP/AL)
- encoder/decoder: Frame Packing SEI Message (AL)
- decoder: Minor CABAC updates (AT)
- encoder/decoder: Update work spaces for VS 2008 and XCode with x64 and OPENMP support (KS)
- encoder/decoder: Update Makefiles for OPENMP support (KS)
- encoder: avoid crashes by prohibiting incompatible tool combinations (KS/YHE)

11th Multimedia Metadata Community Workshop on Interoperable Social Multimedia Applications (WISMA 2010)

On May 19-20, 2010 I've attended the 11th Multimedia Metadata Community Workshop on Interoperable Social Multimedia Applications (WISMA 2010) in Barcelona, Spain. The proceedings are available online on CEUR-WS.org and Twitter stream in case you'd like to review it.

I had two presentation which I'd like to provide here. The first one was on A Metadata Model for Peer-to-Peer Media Distribution:

Abstract: In this paper we describe a metadata solution for a Peer-to-Peer (P2P) content distribution system termed NextShare. We outline the key motivating factors for our approach, detail the overall generic architecture we have developed and present the workflow for delivering metadata through Peer-to-Peer based content distribution. The paper also presents the metadata model we have developed and we describe in detail how all the content can be packetized and distributed using NextShare. Finally, a description of the core and optional metadata attributes which may be utilized within the system is provided.

The second presentation provided an answer for the following question: Are Sensory Effects ready for the World Wide Web?

Abstract. The World Wide Web (WWW) is one of the main entry points to access and consume Internet content in various forms. In particular, the Web browser is used to access different types of media (i.e., text, image, audio, and video) and on some platforms is the only way to access the vast amount of information on the Web. Recently, it has been proposed to stimulate also other senses than vision or audition while consuming multimedia content through so-called sensory effects, with the aim to increase the user’s Quality of Experience (QoE). The effects are represented as Sensory Effects Metadata (SEM) which is associated to traditional multimedia content and is rendered (synchronized with the media) on sensory devices like fans, vibration chairs, lamps, etc. In this paper we provide a principal investigation of whether the sensory effects are ready for the WWW and, in anticipation of the result, we propose how to embed sensory effect metadata within Web content and the synchronized rendering thereof.

MPEG Press Release: Proposals for HEVC demonstrate substantial compression gains for video coding

--full press release available here.

Dresden, DE – The 92nd MPEG meeting was held in Dresden, Germany from the 19th to the 23rd of April 2010.

Highlights of the 92nd Meeting

• Joint Collaborative Team on Video Coding evaluates 27 proposals for HEVC
• MPEG issues Call for Proposals for streaming MPEG media over HTTP
• MPEG-U for Rich Media User Interfaces is completed
• New BIFS Profile for enhanced Mobile Services is ready to be deployed
• Amendment to MPEG-7 Defines Robust Technology for Video Signatures

Details for each highlight can be found in the full press release.

Digging Deeper – How to Contact MPEG

Communicating the large and sometimes complex array of technology that the MPEG Committee has developed is not a simple task. The experts past and present have contributed a series of white-papers and vision documents that explain each of these standards individually. The repository is growing with each meeting, so if something you are interested is not there yet, it may appear there shortly – but you should also not hesitate to request it.

Special Issue on

Intelligent Multimedia Systems and Technology

Recent years witnessed the explosion of multimedia data on the Internet, desktop and mobile devices, and there has been an increasing demand of intelligent systems and technology to understand, index, manage, search and consume these data. Machine learning and data mining have proven to be promising approaches in many data-intensive applications, and many such efforts have also been dedicated to multimedia data. The objective of this special issue is to bring together latest research along this direction. We look for effective machine learning and data mining algorithms, frameworks, systems, and implementations that particularly work on multimedia data (including image, video, and audio, which may be also associated with textual information). The focus is to identify real challenges in intelligent multimedia systems and technology and to investigate practical solutions to the core problems of multimedia applications in both theoretical and practical perspectives.

Topics of interest include but not limited to:

(1)    Intelligent systems for multimedia data management, index, search and sharing.

(2)    Machine learning technology for image, video and audio content understanding.

(3)    Machine learning technology for multimedia search.

(4)    Mining of multimedia data (image, video, audio, or any combination of them).

(5)    Social media analysis and mining.

(6)    Intelligent technology for Internet multimedia search.

(7)    Large-scale learning and mining algorithms for multimedia data.

We will publish two issues on this topic, and the two issues have different submission deadlines.
