Why? Consumer interest in TV content.
ARD/ZDF Online Study 2014 „Second Screen: Parallelnutzung von Fernsehen und Internet“

Consumers rely on companion devices

Frustration in meeting an information need
„... a true TV ecosystem must functionally integrate the apps with the television programming service and content being offered to the consumer.“
TVs can't be smart. Stop trying to make it happen. - WIRED Opinion, Gary Myer, Oct 2013

Companion screen apps haven‘t succeeded
(yet?)
Why aren‘t they succeeding?
• Check-ins and Social Web aren‘t enough
• Users miss deeper integration with the content of the TV program
• Broadcasters prefer control and access to user instead of giving it to OTT offers
6
The concept of Linked Television
meet the viewer‘s information need• directly associated with the TV program
• easily accessible for the viewer• under the control of the broadcaster

Issues preventing broadcast TV use
Issue Explanation
Identifiers Move from Web URL/URI to Broadcast DVB URLs
• Identifiers for a distinct program - not a specific
locator for a program stream (live, repeat, on
demand) - used for association with annotations
Metadata Move from Web metadata best practices to broadcast
metadata lack of best practice; choice of metadata
model
• LinkedTV metadata much more fine grained than
EPG data, lack of a standard model for this
• No best practice how an application can get the
metadata for a TV program
Fragments From W3C Media Fragment URI support to ?
• Used to reference occurrence of entities inside the
program
• Temporal offset needs to be measured against the
start time (0s) of continuous media

Issues preventing broadcast TV use - 2
Issue Explanation
Multi-screen Browsing enrichments in depth is best done on a
separate screen to the TV content
• The main screen needs to find a companion screen
and establish a connection to it, with permissions to
open content via URL
or
• The companion screen can ask the main screen for
the identifier of the content it is showing to open the
associated enrichment directly
and
• Main and companion screens would stay in sync

background to the news
Focus on key concepts of
interest in each item
hbbTV single screen and

• Agreement on identification of TV content
Support for the Media Fragment URI 1.0 specification in TV media
players, STBs
Consistent implementation of spatial and temporal markers for
Broadcast TV (e.g. set start point of segments via StreamEvents)
Description and addressing scheme for rich TV annotations (e.g. via
WebVTT Timed Annotation Track, using TVAnytime extensions)
• HbbTV apps need to be able to send and sync content on a companion
screen
Our position on HbbTV 2.0
