CERTH just publicly released an advanced edition of its software for the automatic temporal segmentation of videos into shots, i.e., the division of the video in sequences of consecutive frames captured without interruption by a single camera. The released software can detect both abrupt and gradual shot transitions with high accuracy, and makes use of CUDA-based parallel computing capabilities of modern PCs for making the whole analysis process at least 2-3 times faster than real-time processing (depending on the processing capability of the PC’s graphics card). The development and release of this software was supported by EU research projects LinkedTV (http://www.linkedtv.eu/) and MediaMixer (http://www.mediamixer.eu/).
The software is available for download at http://mklab.iti.gr/project/video-shot-segm

LinkedTV is pleased to announce that the program for the 2nd Linked Media workshop (LiME) to be held on May 25, 2014 during ESWC 2014 has been published on the event page.
The Linked Media workshop wants to bring together Linked Data and (semantic) multimedia researchers and practitioners to discover and discuss the benefits of the overlaps between Linked Data as a global unique concept space and semantic annotation of multimedia as a means to improved media retrieval and re-use. Ultimately, publishing annotations online using Linked Data can help promote new applications of media retrieval and re-use across the Web.
The Linked Media workshop program includes a keynote talk by Sebastian Schaeffert, a leading researcher in the overlap between Linked Data and multimedia as well as lead developer of Linked Media Framework (now Apache Marmotta). It also has 3 research presentations and 2 research demos, covering topics in TV, cultural heritage, social media and online annotation tools. We look forward to seeing you there!
Join our Linked Media workshop at ESWC 2014 this summer and participate in a fresh discussion about Linked Data for multimedia annotation, linking and retrieval.
The demonstrations track is an opportunity for researchers and practitioners to present their innovative prototypes, practical developments, on-going projects, lessons learned and late-breaking results around Linked Data and multimedia.
Submissions welcome until April 8th, 2014.
YOU HAVE ANOTHER CHANCE!
Deadline extended to March 31 for 1 or 2 page submssions to the 5th international workshop on Future Television:
in conjunction with ACM TVX 2014 (formerly EuroITV), Newcastle (UK). To be held on 25th June 2014.
The 5th FutureTV workshop at ACM TVX 2014 will explore the new possibilities for television that can be realised through the LinkedTV vision of interweaving seamlessly TV and Web content, and particularly how this seamless interweaving can be used to build new forms of interactive stories around streamed audiovisual and Web content.
We solicit research and development papers which present original new work that could be part of future “Linked Television”, drawing from the experiences made in interactive storytelling. Researchers are invited to submit max. two page proposal papers that describe current research results and present their potential contribution to the creation of Interactive Stories through the seamless interweaving of TV and Web content.Practitioners and developers are invited to submit max. one page demo papers that describe a tool or service and how it can contribute to Interactive Story creation.
Submission deadline is now March 31, via http://www.easychair.org/conferences/?conf=futuretv2014.
LinkedTV participated in the 4th W3C Web and TV workshop in Munich on March 13, 2014. The workshop is subtitled ‘Aligning Global Standards and what’s next for Web and TV’, and LinkedTV certainly believes a closer, more relevant convergence of TV and Web content is one of those things which is “what’s next for TV”. Currently, anything from 58 to 77% TV viewers are also using a second screen on an Internet-connected device at the same time as TV viewing, and one survey found 40% of viewers using that screen to follow what was going on – with Google the first place to search for program-related information.
Scientific co-ordinator Lyndon Nixon and platform development lead Jan Thomsen delivered a presentation on “Linking Web Content Seamlessly with Broadcast Television: Issues and Lessons Learned” (PDF). The talk reflects on LinkedTV’s re-use of the “Open Web Platform” in its front end development, where a shared support for Web standards like HTML5 promises a cross-platform and cross-device technology for enriching the TV experience with links to Web content. Areas like TV program identification, extended metadata injection into the broadcast stream, companion device discovery and screen control as well as a consistent support for synchronisation of content to broadcast via Media Fragment URIs were covered in the brief presentation. Our slides have been published online.
Attending the European Data Forum 2014? “Developing a second screen application for TV broadcasts enriched via Linked Open Data“ has been accepted as a poster presentation in Athens, Greece, to be shown on the 19th March 2014, 6-8pm.
Increasingly, European citizens consume television content on, or with, devices connected to the Internet where they can look up related information. In parallel, Europe is publishing growing amounts of Linked Open Data, including rich metadata about its cultural heritage. The LinkedTV project’s goal is to seamlessly interlink TV and Web content to enrich the user’s experience of both. Linked Data and semantic technologies enable broadcasters to achieve added value for their content at low cost through the re-use of existing and extracted metadata.
We will present at EDF2014 two user studies (on Interactive News and the Hyperlinked Documentary) and the end-user interface for a second screen application for Linked Television. We invite all EDF attendees to visit our poster and discover how Linked Data is applied in dynamically enriching TV content.
LinkedTV is pleased to announce that its position paper “Linking Web Content Seamlessly with Broadcast Television: Issues and Lessons Learned” (PDF) has been accepted for presentation at the next W3C Web and TV workshop in Munich on March 13, 2014.
The workshop is subtitled ‘Aligning Global Standards and what’s next for Web and TV’, and LinkedTV certainly believes a closer, more relevant convergence of TV and Web content is one of those things which is “what’s next for TV”. Currently, anything from 58 to 77% TV viewers are also using a second screen on an Internet-connected device at the same time as TV viewing, and one survey found 40% of viewers using that screen to follow what was going on – with Google the first place to search for program-related information.
However, viewers have limited means to conduct many of the information searches they desire, e.g. finding out which painting is hanging on the wall behind a character is nearly impossible to formulate as a textual query to Google, such searches do not occur. On the other hand, providing such links as an additional service via connected devices can be a means to create new value for original television content.
Linked Television seeks to address this by providing media owners such as broadcasters an integrated Platform for ingesting, analysing and annotating their video material, and on playout adding links from video to related Web content which can be presented to the viewer on their second screen via the LinkedTV multiscreen toolkit.
However, this functionality relies on support of the “Open Web Platform”. If LinkedTV is to become a truly cross-platform and cross-device technology for enriching the TV experience with links to Web content in the household, support for LinkedTV-ready Web specifications such as HTML5 and APIs for device discovery, content synchronisation and Media Fragments need to be part of the next generation of Consumer Electronics devices (and not just PCs being used like TVs).
We hope our presentation and subsequent discussions will be the start of a process to bring Linked Television into households via device support for new specifications, many of which are being pushed by the W3C.
