MPEG Multimedia Standards Workshop

Purpose

Mutlimedia technologies have played an essential role in the deployment of many consumer and professional products and services around the world. Multimedia technologies have entered the common people’s life now. All indications show that, as in the past, they will continue to play an important role in the deployment of future products and services. This workshop will present some of the new multimedia technologies and their achievements and their applications, especially in audio, video standardizations and technologies as defined and studied by ISO/IEC JTC1 SC29 WG11, ITU-T SG16 Q.6 and AVS Working Group of Ministry of Information Industry of China.

Host & Date & Venue

Workshop on Multimedia New Technologies and Applications is hosted by Xidian University, Xi'an, China.
Workshop will be held on Saturday 31 Oct. 2009 (a full-day meeting).
Conference room is in Library of Xidian University.
Open to all MPEG and JPEG members.

iTunesLP: The "first" (MPEG-21) Digital Item?

Apple recently released iTunesLP with which "the visual experience of the record album returns". Today, I've purchased the first iTunesLP (btw. 1st iTunes music thing ever!) to see what's behind this 'new format' and whether it can be considered as a digital item (as defined by MPEG-21). The album in question is "The Doors: 40th Anniversary Mixes" and comes with the regular media files which are placed in the regular iTunes directory structure. However, it also comes with a .itlp 'file' - at least this is what Mac OS X finder shows (cf. figure below).
However, what's behind is a simple directory structure comprising an index.html linking to a set of CSS files (css) and JavaScript files (controllers and src). Furthermore, the directory structure includes links to fonts, images, and videos required for the presentation of the LP and an Apple .plist file. The views directory provides something like the sub-pages from an album's booklet.
That is, the iTunesLP is basically a Web site (i.e., HTML+CSS+JavaScript) and iTunes becomes a ordinary Web browser? Hmm, finally I tried to transfer the iTunesLP to the iPhone but it seems that the iPhone cannot play the album in the same way iTunes does.

On the other hand, is it possible to realize the functionality provided by iTunesLP with MPEG-21 tools? I would say "Yes, it can"! In particular, the relationship between the various assets (text, images, videos, etc.) can be described using Digital Item Declaration and Digital Item Identification is used to identify the whole album and individual tracks. The interaction can be achieved by Digital Item Processing which enables the inclusion of ECMAScript (JavaScript) within a Digital Item. Finally, the File Format provides means to package the digital item into a single file - based on the ISO base media file format and compatible to .mp4 - enabling easy transaction among users within the whole value network.

So, is the iTunesLP a digital item? - Yes! Is the iTunesLP compatible with an MPEG-21 Digital Item - No (it is not compliant to MPEG-21) / Yes (it can be realized using MPEG-21). Additionally, MPEG-21 provides means to package a Digital Item into a single file and it is interoperable.

Advanced IPTV Terminal (AIT): Ad-hoc Group Meeting in Milan, Sep 2009

Milan has not only the 'Duomo' (see picture below) but was also the host for the AhG meeting (Sep 10-11) on Advanced IPTV Terminal (AIT), one of MPEGs newest exploration activity. The output is publicly available and provides the following documents:
Please note that these documents have not been approved by MPEG yet. However, these documents form the basis for a Call for Proposals (CfP) hopefully issued during MPEG's next meeting in Xian.

MobiMedia & EUMOB 2009 Revisited

Last week I've been at MobiMedia and EUMOB 2009. The program started with a tutorial from Fernando Pereira about "Mobile Video Coding" starting from good old object-based coding introduced in MPEG-4. The concept of objects in video is there (i.e., production, etc.) but not yet in our house. He still believes in the concept of object-based video coding! In fact, flexible macroblock ordering (FMO) introduced in Advanced Video Coding (AVC) can be used to simulate object-based coding by grouping slices and prioritize them separately.

One keynote was given by Bernd Girod about Mobile Image Matching – Towards Mobile Augmented Reality. The concept is as follows: (1) Take photo on mobile device, (2) extract certain features, (3) transmit feature to server, (4) do processing on server (e.g., search for associated information about what is on the picture), and (5) send reply to device. This safes bandwidth as the picture does not have to be uploaded to the server, only the feature descriptor which is considerably smaller than the picture itself. And, it works - great ... overall interesting work and lot of people were involved in this project (>10).

Another keynote given by Chang Wen Chen was about "Mobile and Networked Video: A Challenging New Era". He introduced True Ubiquitous Video which is Mobile to Mobile that requires low complexity both at the encoder and decoder. Current coding schemes such as (Advanced Video Coding) AVC and Distributed Video Coding (DVC) require either high complexity at the encoder or decoder which fits well with the targeted application area. He proposes some kind of transcoding between DVC and AVC streams within the network. However, this is at a very early stage and it is not sure whether it leads to any success. Furthermore, he calls for semantic adaptation with more intelligence but I'm not sure what this exactly means ;-)

Finally, EUMOB had some nice presentations from various EC-funded projects such as FUTON, ADAMANTIUM, InterMedia, and OPTIMIX.
