Oct. 25–27, 2016 – Munich, Germany

FAME at Medientage Munich 2016

Solutions on Virtual Reality, HbbTV, DVB-T and HTML

From October 25-27, FAME will exhibit at Medientage in Munich. Visit us at booth G1.

Together with Institut für Rundfunktechnik (IRT) we'll present an 360° Video-/Audio-App for HbbTV. It is a further development of the Fraunhofer FOKUS Cloud-based 360° Video Playout for HbbTV.

Furthermore, we'll demonstrate the following solutions:

HbbTV 2.0 Companion Screen (with Silent TV function)
HbbTV Application Creation Toolkit (HAT)
Broadcast Probing System

Fraunhofer FOKUS 360° Video Solution Fraunhofer FOKUS

360° Audio-/Video-App for HbbTV

The Fraunhofer FOKUS Cloud-based 360° Video Playout for HbbTV for HbbTV makes it possible to watch 360° video content on low capability devices such as HbbTV. The videostream is rendered on server side what allows high quality 360° video live streaming with low latency.
The object-based audiorender by IRT converts data streams for different platforms, e.g. to the formats binaural, Stereo-Ton and 5.1-Surround. The combination of audio and video rendering enables high quality 360° Video-/Audio-experiences on HbbTV as well as on mobile devices.

Companion Screen Features Fraunhofer FOKUS

HbbTV 2.0 Companion Screen and Media Synchronization Framework with Silent TV-function

The HbbTV 2.0 specification introduces a number of new features that support companion screens and improve the synchronization of broadcast and broadband content. The HbbTV 2.0 CS and Media Synchronization Framework by Fraunhofer FOKUS implements these features. It offers a set of modules and libraries that allow the viewer e.g. to watch additional content on companion screens or to personalize audio tracks on companion devices and choose from multiple camera perspectives.

The Silent TV-function enables multiple viewers in a room to watch a TV program silmultaneously in different languages. Viewers select their individual audio content on a companion screen and listen to the audio stream by headphones. The Silent TV-function with audio- and video-synchronization can be easily integrated in existing HbbTV applications.

Key technologies and standards:

HbbTV 2.0 HbbTVCSManager API
HbbTV 2.0 MediaSynchronizer API
HTML5, WebSocket
SSDP, DIAL, DVB-CSS
Node.js, Android, iOS, Cordova

HbbTV Application Toolkit

Creating HbbTV apps made easy

The HbbTV Application Toolkit – HAT – presents a CMS for creation of HbbTV applications, which allows content creators without specific technical skills to build interactive TV applications and is developed by Fraunhofer FOKUS' Competence Center Future Applications and Media (FAME). So far HAT covers a simple themes collection which can be accessed through the editor UI. Here the content editor can choose from different layouts and designs regarding the background and color scheme. The layouts include basic modules, broadcast or IP-video, text, image and live blog. The live blog includes an external live blog coming via social media APIs. We see a great potential in the uptake of programme-related HbbTV apps creating new markets for developers and technology providers. HbbTV Application Toolkit Editor HAT provides an editor/CMS with a set of GUI templates that can be filled with text, images audio and video content via a responsive user interface for desktop and mobile devices alike. The content palette can be extended by customized modules, e.g. for display of social-media feeds. The toolkit includes a collection of templates and modules, allowing control of all application elements including broadcast source, IP video source, images, text, picture gallery, social media feeds, popups and overall application layout. When creating more than one page, a navigation menu is automatically generated.

Benefits

Fast and easy creation of programme-related HbbTV applications
Provides a set of App templates tailored to the TV screen
Content can be added via an easy to use web interface
Supports HbbTV app developers by offering templates and modules like interactive video and photo gallery, text, menus, social media and companion screen support

Broadcast Probing System

Cloud-based monitoring of DVB-T/T2 networks

Linked data for service quality and experience gain in DVB-T/T2 networks. Digital service broadcast suffers from misconfigurations at the source and dynamically changing signal propagation conditions. The lack of feedback leads to undisclosed service degradation and decreased experience. Selective professional monitoring is costly and often not enough to cover large areas.

Our Broadcast Probing System offers cloud-based continuous near real-time monitoring of broadcast networks by utilizing massively distributed low-cost probes. Controlled either individually or in groups the probes are securely instructed to execute scheduled jobs like scanning, tuning and transport stream inspection. The collected spatiotemporal data links RF characteristics and stream quality (e.g. Signal levels, TS packet errors), multiplexed tables (e.g. AIT/HbbTV, EIT/EPG) and AV dumps to allow for live analysis, evaluation and integration into monitoring environments

Features and assets:

Feedback channel for DVB-T/T2 networks to detect potential misconfigurations and service degradation

Near real-time monitoring of digital service broadcasts (RF level, TS level, AV level, ETSI TR 101 290)

Remote control of individual and groups of low-cost probes (Android, Raspberry Pi)

Execution of scheduled probing jobs and secure instant access (PKI, TLS)

Analysis and evaluation on live and historical linked data (JSON-LD)

Integrates with existing monitoring systems and offers a comprehensive API (SNMP, MQTT, REST/HTTPS).
