dlvr.it: a new star on the RSS syndication market is born?

Recently, I asked via Twitter that I need a "Twitterfeed" tool that distributes RSS items evenly based on previous update rates. Almost instantly, I got a reply by @dlvrit_connect that dlvr.it provides this kind of functionality through its "trickle" mode. I also got an invite code which gave me the possibility to give this tool a try.


Before going into details, I'd like to give some background. As associate editor for Computing Now I'm using the well-known Twitterfeed to automatically feed RSS items into the CN Twitter account. It works very well but the main problem is that some source RSS feeds are published in bursts (e.g., more than 10 items at a time) and having more than three tweets at a time is probably not well received by our followers. It's difficult to change this situation and, therefore, I was hoping that with dlvr.it it is possible to distribute these "burst-ish" feeds more smoothly over time.

Fortunately, dlvr.it offers the following update mechanisms:
As others tools, it allows one to define the update period, maximum number of items to post per update period, and maximum number of items to post by day. Additionally, one may specify to trickle items over time which offers three possibilities (copy/paste from dlvr.it help):
  • Trickle Off: updates your feed and looks for newly published items to post. New items (up to the "Max Number of New Items to Post per Update Period" set for your feed) will post. Newly published items not posted during an update period will be marked as 'seen' and are not eligible for posting later. For example, if during the feed update period your feed has 7 new items, and the "Max Number of New Items to Post per Update" is set to 5, then 5 new items will post and 2 will be marked 'seen' and will never post. 
  • Post Oldest Items First: Items will be posted beginning with the oldest and working forward. During each feed update, the oldest, previously unposted items (up to the "Max Number of New Items to Post per Update Period") will post. Items not posted during feed update will be eligible for posting later.
  • Post Newest Items First: Items will be posted beginning with the newest then working back. During each feed update period, the newest, previously unposted items (up to the "Max Number of New Items to Post per Pull") will post. Items not posted during feed update will be eligible for posting later.
I think this functionality is a major improvement over Twitterfeed which simply allows to specify the update frequency and the maximum number of items to post at a time.

Destinations other than Twitter include - among others - Facebook and LinkedIn which are equally important for Computing Now. Unfortunately, only status updates are possible but I would need updates to CN's Facebook Page and LinkedIn Group.


Finally, there are also means for defining a prefix, suffix, filters, auto-hashtag placement (based on feed categories), multiple bit.ly accounts (instead of built-in dlvr.it shortener), etc. You may also read the TechCrunch article related to dlvr.it which gives a broader overview of the actual services offered.

CTRQ2010: A Novel Architecture for Multimedia Distribution based on Content-Aware Networking

Here comes the abstract of our paper that has been accepted for publication at CTRQ2010. Please join us there in case you'd like to get in touch we us!

E. Borcoci, D. Negru, and C. Timmerer, "A Novel Architecture for Multimedia Distribution based on Content-Aware Networking", accepted for publication at the 3rd International Conference on Communication Theory, Reliability, and Quality of Service (CTRQ 2010), Athens/Glyfada, Greec, June 13-19, 2010.

Abstract: This paper proposes a novel virtual Content-Aware Network (CAN) layer as a part of a full layered architecture, focused, but not limited to, on multimedia distribution with Quality of Services (QoS) assurance. The overall system is based on a flexible cooperation between providers, operators and end-users, enabling users to access the offered multimedia services in various contexts and also to become private content providers. The paper introduces the main concepts and architecture for the main virtual network layer (i.e., CAN), exposing its role and interfaces among overall system layers. This work is a part of the starting effort inside of a new European FP7 ICT research project, ALICANTE.

Acknowledgment: This work was supported in part by the EC in the context of the ALICANTE project (FP7-ICT-248652). Further information can be found at http://www.ict-alicante.eu/.

* CONFERENCE BACKGROUND AND GOALS

Multimedia information has become ubiquitous on the web, creating new challenges for indexing, access, search and retrieval. Recent advances in pervasive computers, networks, telecommunications, and information technology, along with the proliferation of multimedia mobile devices - such as laptops, iPods, personal digital assistants (PDA), and cellular telephones - have stimulated the development of intelligent pervasive multimedia applications. These key technologies are creating a multimedia revolution that will have significant impact across a wide spectrum of consumer, business, healthcare, and governmental domains. Yet many challenges remain, especially when it comes to efficiently indexing, mining, querying, searching, and retrieving multimedia data. The Multimedia - Processing and Applications 2010 (MMAP 2010) Symposium addresses several themes related to theory and practice within multimedia domain. The enormous interest in multimedia from many activity areas (medicine, entertainment, education) led researchers and industry to make a continuous effort to create new, innovative multimedia algorithms and application. As a result the conference goal is to bring together researchers, engineers and practitioners in order to communicate their newest and original contributions on topics that have been identified (see below). We are also interested in looking at service architectures, protocols, and standards for multimedia communications - including middleware - along with the related security issues, such as secure multimedia information sharing. Finally, we encourage submissions describing work on novel applications that exploit the unique set of advantages offered by multimedia computing techniques, including home-networked entertainment and games. However, innovative contributions that don't exactly fit into these areas will also be considered because they might be of benefit to conference attendees.

CfP: Workshop on Impact of Scalable Video Coding on Multimedia Provisioning (SVCVision)

Collocated with MobiMedia - 6th International Mobile Multimedia Communications Conference
6th-8th September 2010 - Lisbon, Portugal

http://www.mobimedia.org/ws_SVCVision.html


Aims and Scope
===============
Scalable Video Coding (SVC) refers to the possibility of removing certain parts of a video bit stream in order to adapt it to a changing usage environment, e.g., end device capabilities, network condition or user preferences. SVC has been an active standardization and research area for at least 20 years, reaching back to H.262/MPEG-2, which offered scalable profiles. However, these previous attempts suffered from a significant loss in coding efficiency as well as a large increase in decoder complexity (and thus energy consumption), which hindered market adoption. Only the most recent attempt, i.e., the SVC extension of H.264/AVC, focuses on avoiding these disadvantages. Since H.264/SVC standardization started in 2003, it has been at the focus of many multimedia research groups.

Today's increasing variety of end devices (smart phones, tablet PCs, Netbooks, Laptops, PCs, networked HDTVs, …) and the associated multitude of Internet connectivity options (GPRS/EDGE, UMTS, ADSL, PLC, WiMAX, …) provide particular momentum for SVC, which can be easily and pervasively adapted to these various usage environments. SVC also allows end devices to only decode a sub-set of the SVC bit stream, thus enabling in particular mobile end devices to minimize the necessary (processing) power requirements.

This workshop aims to provide a forum for both academic and industrial participants to exchange and discuss recent advancements and future perspectives of SVC.


SVC topics of interest include, but are not limited to:
==========================================
- Robust streaming, error resilience and error concealment
- Streaming in heterogeneous environments
- Peer-to-Peer (P2P) video distribution
- Internet Protocol television (IPTV)
- Energy-efficient video distribution
- Content adaptation (e.g., scaling, rewriting, transcoding) and summarization
- Complexity optimization and new tools for achieving scalability
- Adaptation decision taking & context information
- Storage & file format
- Conditional access & protection
- Novel applications & implementation experiences


Important Dates
==============
Paper Submission:  23. April 2010
Notification:          28. May 2010
Camera Ready:  25. June 2010


All accepted papers will be published in Springer Lecture Notes of ICST (LNICST) series and included in major article indexing services.

O Universal Multimedia Access, Where Art Thou? (Part IV)

-by Christian Timmerer, Klagenfurt University, Austria

Preface: First I thought about writing this article for a journal or something equivalent but then I concluded to make this article available through my blog. The aim is to perform an experiment in order to determine whether it is possible (a) to get direct feedback through comments and (b) to be referenced from elsewhere. As it is a quite comprehensive article, it’s split up in separate parts. If someone (i.e., a journal editor) is interested in publishing this article, yes, I can still do that! :-)

Part I was about giving an introduction to the topic and an overview on multimedia content adaptation techniques. Part II was about the adaptation by transformation approach that utilizes scalable coding formats such as JPEG2000, MPEG-4 BSAC, and MPEG-4 SVC. Part III comprises adaptation decision-taking also known as the brain of multimedia content adaptation and this part is about standardization support for UMA.

Part IV - Standardization support for UMA


The nice thing about standards is that there are so many to choose from. Furthermore, if you do not like any of them, you can just wait for next year’s model.
--Andrew S. Tanenbaum

A couple of standardization organizations (SDOs) provide support for UMA:

Word Wide Web Consortium (W3C): http://www.w3.org/
Internet Engineering Task Force (IETF): http://www.ietf.org/
  • Audio/Video Transport (AVT)
  • Media Server Control (MEDIACTRL)
  • Multiparty Multimedia Session Control (MMUSIC)
  • Session Description Protocol (SDP) and Session Initiation Protocol (SIP)
  • Next Steps in Signaling (NSIS)
Moving Picture Experts Group (MPEG): http://www.chiariglione.org/mpeg/
A comprehensive description format with respect to UMA is Part 7 of MPEG-21 entitled Digital Item Adaptation [2]. This part of MPEG-21 defines - among others - the Usage Environment Description (UED) providing means for describing the context in which Digital Items may be consumed. The UED is clustered into the following categories with some examples given:
  • User Characteristics: e.g., usage history, display presentation preferences, audio/visual impairments, mobility, etc.
  • Terminal Capabilities: e.g., coding capabilities, display capabilities, audio output capabilities, etc.
  • Network Characteristics: e.g., network capabilities (e.g., max capacity, min guaranteed) and conditions (e.g., available bandwidth)
  • Natural Environment Characteristics: e.g., noise level, illumination characteristics, location, time, etc.
The UED is defined as an XML Schema which is publicly available here.

This is the end of Part IV and I'm currently not sure whether a Part V will follow...

    Mobile Storytelling featuring Streaming Media based on the MPEG Extensible Middleware

    --Joint bachelor thesis of RWTH Aachen and Klagenfurt University

    Mobile Storytelling covers the creation, editing, and consumption of multimedia stories on mobile platforms. Mobile Stories are essential for knowledge sharing within (professional) communities. The mobile multimedia experience of users is critical for the appropriation of multimedia knowledge sharing. This application shall support the streaming / progressive download of media such as audio/video content to mobile platforms such as iPhone and Android including a possible transcoding on the server side. In particular, the MPEG Extensible Middleware (MXM) shall be implemented for these platforms supporting the above application in order to guarantee interoperability among the involved entities. A rudimental streaming library for these platforms is provided as a starting point but probably requires some extensions. Furthermore, the MPEG Extensible Middleware (MXM) is also not set in stone and can be extended if necessary which may lead to a submission to ISO/IEC MPEG co-authored by the bachelor candidate. We look forward to working with bachelor candidates who are interested in this kind of application, streaming media, middleware, and interoperability.

    Beyond the Internet? − Innovations for future networks and services

    ITU-T Kaleidoscope event, Pune, India, 13-15 Dec 2010
    Beyond the Internet? - Innovations for future networks and services - is the third in a series of peer-reviewed academic conferences that aims at increasing the dialogue between experts working on the standardization of information and communications technologies (ICTs) and academia. By viewing technologies through a “Kaleidoscope”, these forward looking events also seek to identify new topics for standardization.
    Thus far, the Internet has proven to be robust and flexible and its continuous evolution has seen growth from a small experiment into a giant collaborative network capable of meeting the demands of more than one billion users. The rise of mobile access and its integration with optical transport networks present new challenges. Some experts question whether the current underlying architecture is sufficiently robust to address future demands or if a “clean slate” approach is needed to develop a really innovative Internet of the future.
    Kaleidoscope 2010 will highlight multidisciplinary aspects of future Information and Communication Technologies (ICTs) including future services and applications demand as well as social and economic impacts. The focus will be on innovative technologies and contributors might have to challenge the fundamental networking design principles of the Internet.
    This academic conference is calling for original papers, from the world’s universities, industry and academic institutions. Accepted papers will be made available through the IEEE Xplore. A prize fund totaling $10,000 will be awarded by the three best papers. Young Author Recognition certificates will be also issued.
    New this year
    In addition to a local universities exhibition, outstanding keynote speakers and invited papers, ITU Kaleidoscope 2010 will host Standards corner, a series of standardization tutorials and Jules Verne’s corner, a special space for science fiction writers and dreamers.

    ACM Multimedia Grand Challenge 2010: Content Adaptation

    One of the ACM Multimedia Grand Challenge 2010 is about content adaptation, probably one of THE tools providing Universal (Multi-)Media Access (UMA). In particular, it is called "Radvision Challenge 2010: Real-time Data Collaboration Adaptation for Multi-Device Video Conferencing" and details can be found here with the input/output described as follows:
    Input for this challenge is a video capture of a free-hand drawing (see example video) in XGA.
    Output for this challenge should be a set of “adapted” videos , with the same content in different (smaller) resolutions – for instance, VGA and QVGA. The adapted videos would ideally be regarded by users as perceptually optimal, meaning they hold the same content as the original.
    The metrics for evaluation are "defined" as follows:
    The following criteria could be used, as well as other evaluation metrics that you may devise:
    1. Subjective comparison between the perceptual quality of the original and the “adapted” content.
    2. Subjective comparison between the perceptual quality of a scaled-down version of the original (using a 5-tap poly-phase filter) and the “adapted” content.
    3. Real-time Performance.
    However, there are many possibilities to adapt content and evaluate the result which heavily depends on the user's context. Some people may think that the description of the input/output as well as the evaluation criteria is defined too vague and I tend to agree. Let me explain:
    1. The input is given and for the output it is requested to produce "a set of adapted videos" that is "regarded by users as perceptually optimal". However, it's not clear to which context the input shall be adapted. The text says "different (smaller) resolutions" as an example but I can imaging that users will prefer the original video and regard it as perceptually optimal compared to anything else. Thus, in my view it is necessary to specify the context to which the video shall be adapted. The context may include a lot of things such as terminal device, decoding capabilities, network conditions, user location (stationary, mobile), etc., etc.
    2. Subjective quality assessment is not an easy task and there are many possibilities and many approaches. Form the description above it is not clear how the subjective quality evaluation will be performed. In particular, I wonder whether "real" subjective tests as suggested by the Video Quality Experts Group (VQEG) will be adopted (e.g., DSIS - Double Stimulus Impairment Scale or ACR - Absolute Category Scale to just name two). In my view and in order to provide a fair evaluation it is absolutely necessary to define the exact procedure on how the subjective evaluation of the submissions will be performed. One possibility, of course, is the adoption of a standardized approach and probably DSIS is the right candidate.

    Special Session: “Advances in Multimedia Delivery” (AMD)

    TEMU 2010 – INT. CONF. ON TELECOMMUNICATIONS AND MULTIMEDIA
    JULY 14-16, 2010, CHANIA, CRETE, GREECE
    http://www.temu.gr

    Scope

    Latest advances in multimedia content encoding and representation, including HDTV, 3DTV, multi-view video and associated added-value interactive services, are offering to the end user a truly rich multimedia experience. On the other hand, the scope of media delivery itself is expanding beyond traditional broadcast TV to active content sharing among all users. It is thus self-evident that the reliable, efficient and timely handling of all these enhanced multimedia services is not only a sine qua non but also a significant challenge for new wired and wireless networking architectures. Future networks, at core and access level, should be able to provide to the end user ubiquitous access (at home, at office and on the move) to both live and on-demand rich media content. Towards this aim, a significant number of research efforts are being carried out throughout the world.

    The following research areas fall within the scope of this Special Session:
        * Next-Generation infrastructures for multimedia delivery
        * Satellite and terrestrial multimedia broadcasting systems
        * Mobile TV
        * Interactive broadcasting
        * IP and non-IP transport and session control protocols
        * IPTV platforms and standards
        * Web Radio and WebTV
        * Peer-to-peer streaming architectures
        * Scalable media transmission
        * Error protection and concealment
        * AAA (Authentication, Authorization, Accounting) issues
        * Security, encryption and digital rights management for multimedia content
        * Quality of Service and Quality of Experience
        * Market trends and business aspects
