Using HbbTV and a second screen to link TV programs to related content on the Web

While parallel Internet usage to explore additional information while watching TV is on the rise, TV content owners face excessive costs and technological challenges to provide eased access to that information alongside their own content. Since viewers do not have access to the same background metadata as the content owner, they are often frustrated in their own searches. Linked Television is a concept for interlinked TV and Web content within a shared digital ecosystem under the control of the content owner. In this paper, we describe how we implement a prototype for Linked Television using a HbbTV device as main screen communicating with a second screen such as a tablet used by the viewer to easily access and browse information related to what is seen in the TV program.

Video Retrieval for Multimedia Verification of Breaking News on Social Networks

This paper presents an approach to automatically detecting breaking news events from social media streams, using event detection to collect in near real time relevant video documents from social networks regarding that breaking news. A visual analytics dashboard provides access to the results of the content processing pipeline, providing a rich interactive interface to explore emerging stories and select video material around those stories for verification.

Impact of Destination Promotion Videos on Perceived Destination Image and Booking Intention Change

Destination promotion videos (DPVs) are increasingly being used for online marketing and seen by travellers during the information search process. Yet, scholarly attention to DPVs is scarce and the research question of “how do DPVs influence viewers’ destination image change?” is unresolved. To fill these voids, this study (1) examines the projected image of Macau based on the video content analysis of their latest DPV; and (2) investigates the impact of viewing a DPV on viewers’ perceived destination image and on their behavioural intention to visit Macau. The efficacy of repeating—a framing method introduced by Entman (1991)—in influencing change in the DPV viewers’ image of the destination is highlighted. Findings from the experiment indicate that the content of DPVs and repeating certain shots are effective in positively enhancing travellers’ perceived destination image as well as triggering potential travellers’ interest in further researching and visiting the destination.

Delivering related web content synchronized to online television: The LinkedTV solution

This paper describes a solution for synchronized delivery of Web content related to objects and topics present in a parallel online television programme, which we call Linked Television. A content platform prepares the TV programme by analyzing, annotating and enriching it with links to Web content through a combination of innovative Web services. An editor tool allows manual correction and completion of the enrichment. A Web-based player allows multiple devices to synchronise the video and its related content across different screens. The result is a richer TV experience for the second screen generation who, initiated by TV viewing, like to explore further content online. We back this up by pilots using news and cultural heritage programming which have been validated in trials by viewers as enhancing their TV experience.

StoryLens: A Multiple Views Corpus for Location and Event Detection

The news media landscape tends to focus on long-running narratives. Correctly processing new information, therefore, requires considering multiple lenses when analyzing media content. Traditionally it would have been considered sufficient to extract the topics or entities contained in a text in order to classify it, but today it is important to also look at more sophisticated annotations related to fine-grained geolocation, events, stories and the relations between them. In order to leverage such lenses we propose a new corpus that offers a diverse set of annotations over texts collected from multiple media sources. We also showcase the framework used for creating the corpus, as well as how the information from the various lenses can be used in order to support different use cases in the EU project InVID for verifying the veracity of online video.

Session details: LIME 2015

The Linked Media workshop (http://www.linkedtv.eu/event/lime2015/) takes place now for the third time, and thus continues to call for more research and development on a concept which we have called Linked Media. Indeed, while this term still has little resonance in the wider R&D community, the actual principles it embodies clearly become more and more relevant with each passing year. Linked Media considers the value of annotation of media resources using Linked Data concepts, with the expectation that the source of an annotation can be a spatial or a temporal fragment of a media (e.g. a video) and that the result of these annotations can be further processed by software and services to create meaningful links between media fragments based on semantic similarity (or difference!).

Re-using media on the web

This tutorial will address the state of the art in the area of online media analysis, annotation and linking, reflecting that a number of Web-based specifications and technologies are now emerging. When combined, they provide the technical solution for media owners to manage and to re-use their online media at a fragment level. These specifications and technologies form a full online media workflow that supports media fragmentation and re-use, which opens means to derive new value from media to media owners, and new models for media acquisition and use for media consumers. Hence, the awareness of and the ability to use these specifications and technologies will be of great importance to future curators and publishers of online media.
