Joyn Launches HbbTV on Philips TVs
The streaming platform Joyn integrated the Inaris HbbTV Solution into their Android TV App for Sony TV earlier this year. This has been launched by end of July and allows Joyn users to access the HbbTV offering of the ARD group. By the beginning of November, Joyn has expanded their offering of HbbTV to cover Android-based Philips TV devices as well.
This significantly extends the group of Joyn users who can enjoy the advantages of broadcast-related content provided via HbbTV. TARA’s Inaris HbbTV Solution for Android is the basis for this seamless integration of HbbTV into the Android app of an OTT streaming platform used by millions of people in Germany.
German Streaming Platform Joyn integrates TARA’s HbbTV Solution
The German streaming platform Joyn offers a wide range of VoD content and a good number of freely accessible linear TV services. The Joyn App is available for many end-user devices such as for Android TV platforms. To support the HbbTV offering on the TV services of the ARD group, Joyn has now integrated our Inaris HbbTV Solution into their Android TV App.
The solution utilises the Chromium browser and the ExoPlayer as part of our Inaris HbbTV Solution for Android TV. HbbTV support in the Joyn App is available on Sony Android TV devices since August 2021.
Please read also our new Success Story about the integration of HbbTV in the Joyn App.
DVB-I and HbbTV: A Device Manufacturer Perspective in the EBU Working Group
With the LiveOn TV application, we developed a flexible and powerful tool to prototype and demonstrate DVB-I distributions. To share best-practices around HbbTV and DVB-I, the European Broadcasting Union (EBU) has launched the “HbbTV Interoperability group” in September 2020.
In cooperation with the German broadcaster Westdeutscher Rundfunk (WDR), we contributed our expertise in implementing DVB-I clients to this group. To do so, we held a presentation about LiveOn TV in one of the group meetings in December 2020.
Please feel free to contact us if you are interested in further details about our DVB-I application and expertise.
HbbTV Symposium 2019: HbbTV on DVB-I Services
The 8th HbbTV Symposium took place in November 2019 in Athens. We as TARA Systems were very happy to talk at this important annual meeting of the HbbTV Association about HbbTV on OTT services. Together with IRT, we demonstrated the world’s first DVB-I client prototype which is able to run HbbTV applications on top of the linear broadcast delivered via DVB-DASH.
Please have a look at our latest video or download our flyer to get an impression of this immersive prototype implementation.
Inaris HbbTV for Android with Java based Middleware
The Inaris HbbTV Solution for Android TV has already been ported to the TV Input Framework to run on top of any TV Input Service. For Android applications which are not TIF based, we now improved our porting API to allow fastest integration with any Java based Middleware.
With this improvement, Android app developers can integrate channel and metadata management as well as media playback directly with our HbbTV Solution in Java. This simplifies the integration work especially for OTT service providers who want to add HbbTV to their application.
HbbTV Test Suite Executed with LiveOn TV Android Application
The LiveOn TV application is our reference application for integration of the Inaris DVB/IPTV Middleware on Android TV devices. We integrated also our Inaris HbbTV Solution based on Chromium into this application. For all on-demand media playback in HbbTV applications the ExoPlayer is used. We are currently verifying the compliance of the LiveOn TV application with the HbbTV standard by running the official HbbTV Test Suite on the NVIDIA Shield device.
7th HbbTV Symposium in Berlin
In November, the 7th HbbTV Symposium took place in Berlin and we also participated to discuss about the current developments and trends in the context of HbbTV. We demonstrated our Inaris HbbTV Solution with the Application Discovery over Broadband feature. One major topic at the symposium was Operator Applications (OpApp), where our approach to use OIPF as the standard middleware API has high synergy to the HbbTV specification.
Also in the area of Targeted Advertisement we discussed with broadcasters and advertisement platform operators about the usage and accuracy of the HbbTV Media Synchronisation feature for replacing adverts in the broadcast. We can now ensure that our Inaris HbbTV Solution including Media Synchronisation is already prepared for Targeted Advertisement.
HbbTV for OTT services shown at IBC 2018
Together with IRT and the OTT streaming service Zattoo, we demonstrated on this year’s IBC how the HbbTV ADB (Application Discovery over Broadband) standard can be used to bring HbbTV application to OTT services. This gives users a unified HbbTV experience with the same applications independent of the broadcast network. The demo was shown on an Android TV platform running our Inaris HbbTV Solution.
Application Discovery over Broadband for OTT Services
During the last year’s event of Medientage, we demonstrated a prototype implementation of the HbbTV ADB standard. This demonstration is mainly focused on DVB-C networks where the HbbTV signalling is not transmitted. For this year’s IFA and IBC we created a demonstration where we focused on ADB for OTT services.
Together with IRT we optimized the usage of ADB in OTT networks and implemented this in our prototype. The demo shows our Inaris HbbTV Solution on top of the Zattoo OTT service running on Android O.

Inaris HbbTV Solution on Android Oreo
Inaris HbbTV on Android Oreo
With Android Oreo, the latest Android version is currently rolled out on many devices in the market. This also applies to Android TV where the new version brings many enhancements, especially for operators who want to build state-of-the-art set-top boxes.
To enable Android TV devices presenting broadcast related content in HbbTV applications, we have now ported our Inaris HbbTV Solution to Android O.
In our reference integration, we use the Chromium browser for application rendering. For media playback the ExoPlayer or any other available player can be used.
ANOPAS Project Successfully Completed
The ANOPAS research project was started in August 2015 with our partners from Fraunhofer FOKUS and TU Berlin and was funded by the Bundesministerium für Wirtschaft und Energie (BMWi). The work on this project was completed in time by July 2017. Meanwhile, the final report has been submitted and thus the project is successfully completed.
During the project time we discussed and developed together with our partners many approaches that will help to improve the users’ streaming experience. One of the outcomes is an architecture that can be used as a framework to develop more powerful and smarter adaptation algorithms in MPEG-DASH. The experience we gathered in this research project has led to a strong improvement of our products and know-how in the streaming domain. Many concepts and ideas are also applicable for other streaming technologies like HLS.
Inaris HbbTV Solution with Chromium
The Chromium browser is one of the most powerful browsers available today. Furthermore, it is open source software and can be modified to fulfil the targeted use case. We have now extended our Inaris HbbTV Solution to support also Chromium based browsers using a new plugin. This platform-independent plugin reduces the integration work in the browser to a minimum and currently supports the HbbTV 1.5 API.
Extensions for HbbTV 2 are under development and will be available beginning of 2018. The underlying and well tested Inaris HbbTV Solution is the basis for the integration of the new plugin and remains unchanged.
Application Discovery over Broadband (ADB) in Inaris HbbTV at Medientage 2017
Signalisation of HbbTV applications always relies on the network which is used to transmit the broadcast signal. If a network does not allow proper signalisation of HbbTV, users experience a lack of HbbTV functionality on their devices.
To overcome this gap, the HbbTV Association specified the standard Application Discovery over Broadband (ADB) which enables terminals to load the correct HbbTV applications even if the signalisation is not available.
We have now extended our Inaris HbbTV Solution to support the ADB standard and present a prototype based on Android TV and Chromium on Medientage 2017 in Munich. Please have a look at our handout describing the showcase.
HbbTV on Android TV with Chromium
Showcasing HbbTV on Android TV with Chromium
Android TV allows TV manufacturers and operators to build state of the art devices with a huge selection of available applications. The Android TV environment provides the user a very good coverage of video-on-demand content, independent from the linear broadcast.
Additionally, broadcasters provide the user more and more broadcast-related content via the open HbbTV standard. To benefit also from this, the Android TV ecosystem can be enhanced with HbbTV functionality.
To have a seamless integration of HbbTV services into the TV application, we extended our Inaris HbbTV Solution to be embedded into the Android TV application, independent of the used input service. This allows operators to integrate HbbTV functionality into their TV application without any middleware adaptation.
The implementation is based on our platform-independent Inaris HbbTV Solution, the open Chromium browser, and powerful ExoPlayer media player for broadband playback. The interaction with the TV Input Service is done using the TV Input Framework (TIF) API.
We have presented our concept at the Android TV Summit at IBC 2017. Watch the video showing our proof-of-concept implementation.
HbbTV 2 Inter-device Media Synchronisation feature using our Inaris HbbTV Solution
HbbTV Inter-Device Media Synchronisation
With HbbTV 2, broadcasters are able to provide their viewers synchronised media content on companion devices. Use cases are for example second camera perspectives of a sports event or sign language speakers for hearing impaired people.
To investigate these and other use cases and to demonstrate a technical solution for this new feature, we decided to work on this topic within a master thesis. One of the outcomes was an Android application using the ExoPlayer to synchronise with an HbbTV Terminal, running the Inaris HbbTV Solution.
HbbTV Operator Applications
The HbbTV Specification Group is currently in the final phase of working on the Operator Application Standard, which was initially started in early 2016. The concepts and mechanisms are already defined and first specification reviews have been started. The new HbbTV standard will allow network operators to provide Operator Applications including their look and feel as well as portals on any device that is compliant to this standard.
We are convinced that this new HbbTV standard will help to provide a better user experience and new services on many networks. Having this in mind, we are actively contributing to the new standard and looking forward to the first release.
Automatic testing with HbbTV Test Suite V9.0
In December 2016, the HbbTV Testing Group released the new version 9.0 of the official HbbTV Test Suite. Starting with this release, the HbbTV Test Suite includes also tests for HbbTV 2 implementations. Meanwhile, the updated version 9.1 which contains a number of additional and corrected tests has been released as well.
We at TARA Systems have already started to integrate the new Test Suite into our continuous integration process to run it fully automatically every night in Jenkins. This is an important step to verify our Inaris HbbTV Solution, also for HbbTV 2 features.
26th HbbTV Interoperability Workshop
TARA Systems participated in the 26th HbbTV Interoperability Workshop at IRT (Insitiut für Rundfunktechnik) in Munich to meet app developers and manufacturers to test the interoperability of HbbTV terminals and HbbTV applications. For this workshop, we focused on testing the interoperability of our HbbTV 2.0 Companion Screen implementation with HbbTV and companion applications.
HbbTV 2.0 Companion Screen Feature shown at Medientage 2016
Inaris HbbTV Solution now supports the HbbTV 2.0 Companion Screen feature
In collaboration with the Institut für Rundfunktechnik, we have set-up a demonstration on how the HbbTV 2.0 Companion Screen feature can be used by companion applications. The demonstration shows an enhanced version of the ARD Mediathek on an Android tablet interacting with an HbbTV capable set-top box running the Inaris HbbTV Solution. This allows the consumer to browse and select live channels as well as on-demand media content in the companion application and directly cast it to the TV screen. The playback can be controlled from the second screen application.
HbbTV 2.0 Media Synchronisation and Companion Screen Release
During the last months, we concentrated on the development of the HbbTV 2.0 features Media Synchronisation and Companion Screen. Now, we are happy to confirm the release date of these two components to be Q4/2016. The first products using the Inaris HbbTV 2.0 extensions are expected to be launched in Q1/2017.
The new components will be available as an upgrade for the Inaris HbbTV 1.5 Solution and as an extension to third party HbbTV solutions. To give you a feeling about the integration effort, we provide an API preview for both components on request. Please don’t hesitate to get in contact with us and evaluate the best way to upgrade or extend your product with HbbTV 2.0.
Performance Improvement of End-to-End Streaming Solutions with HbbTV
Good streaming performance is an important aspect for HbbTV video on-demand and live services delivered via broadband. To analyse, classify, and improve the user experience of these services, we cooperated and advised a master thesis the goal of which was to build an automated testing environment for End-to-End streaming solutions. This environment was built on our Inaris HbbTV Solution running on a Broadcom based customer platform. On server side, various streaming servers, e.g. Flussonic, were used for verification.
The outcome of this master thesis has been published by IEEE with the title “Automated Performance Testing of End-to-End Streaming Solutions over HbbTV Architecture”. The paper can also be downloaded here (Section B, paper ID B21).
Automatic testing of the Inaris HbbTV Solution in Jenkins

We now fully automated our continuous integration environment Jenkins to enable the daily execution of the HbbTV Test Suite. Take a look at the following video to learn more about our testing process:
TARA Systems contributes to the HbbTV 2.0 Operator Extension
The HbbTV 2.0 Operator Applications working group started their activities with a face-to-face meeting in May 2016 in London. We from TARA Systems participated at this meeting and also at the bi-weekly conference calls that are currently established.
The goal of the Operator Application working group is defining the mechanisms of how a network operator can provide HbbTV applications that extend or replace parts of the native TV User Interface. This allows a network operator to provide additional services and a uniform look and feel on any TV device based on HbbTV technology. Furthermore, this extension is intended to keep the compatibility to HbbTV applications provided by the broadcaster. We will continue to contribute our expertise to reach this goal.
For more information read the official press release of HbbTV Association from April 2016.
Future-proof with HbbTV 2.0 extensions
For current and future customers of our Inaris HbbTV Solution, we already started to develop this next major step in the evolution of hybrid broadcast systems. The HbbTV 2.0 upgrade for the Inaris HbbTV Solution is expected to be available in Q4/2016.
The implementation of the HbbTV 2.0 features will be based on the current solution. The extension will be reflected in the high level architecture of our Inaris HbbTV SDK as shown in the following diagram.
Global iTV Research Project successfully completed
Last week, TARA Systems attended the final review of the GLOBAL iTV Project through the European Commission at the IRT Munich. The project has now been successfully completed. The scope of Global ITV, an international EU funded research project was the development of an interoperability scheme for the co-existence of multiple interactivities and connected TV solutions like Ginga and HbbTV on different digital TV platforms based on current web technologies.
Within the review, we could demonstrate a set-top-box prototype implementing the GLOBAL iTV specification as it was defined within the project. Thus, we were able to signal both, Ginga applications as well as HbbTV applications, on the same service. We also demonstrated how to start Ginga applications out of HbbTV applications, which could enable TV devices in the future to show content from both systems.
Furthermore, enhanced HbbTV applications using HTML5 features were shown which is an important aspect when it comes to HbbTV 2.0.
The set-top boxes TARA Systems provided (KTT IP 8300) have been equipped with our DVB Middleware Inaris – enabled to decode ISDB-Tb Streams – and with our HbbTV Solution. Our Brazilian Partner provided the Ginga-NCL Solution.
ANOPAS uses Server and Network Assisted DASH (SAND)
In context of the ANOPAS project, we decided to include parts of the recently published MPEG-DASH SAND standard (ISO/IEC 23009-5) into our further development activities. The SAND standard (Server and network assisted DASH), defines an architecture and the protocols to allow DASH clients reporting metrics to servers and assist clients on their adaptation decisions.
The ANOPAS project will base their communication protocol on SAND and implement some of the SAND features. This will be for example the coordination of multiple clients sharing the same network resources. In this case, clients will issue a request to participate in resource sharing on the network. Following this, the server will assign them the maximum bandwidth in order to ensure the best use of the available resources. The distribution of the bandwidth to each single client may be influenced by resource allocation strategies e.g. fairness or pricing.
Fully Automatic Execution of the Official HbbTV Test Suite v8.1.0
With the release of the current HbbTV test suite v8.1.0 the number of tests has increased from around 400 to over 950. To enable the daily execution of the HbbTV test suite, it was essential for us to further automate our test environment, which has been in use since the beginning of 2014:
By using an HDMI grabber, it is possible to record video and audio during the execution of tests, without experiencing losses. Picture and sound are then automatically analysed via special software tools. An image or sound reference is stored to this effect in the test system for each test, the results of which can be determined without the interaction of a tester. This step is a prerequisite for the HbbTV 2.0 test suite, which is expected to be extended by more than 480 tests.
Developing Companion Screen Functionality
The companion screen feature enables the interaction of an HbbTV terminal (e.g. Set-top box) with a companion device (e.g. Tablet device). It allows to launch a companion screen application or the other way around, remotely launching an HbbTV application. Additionally an “application-to-application communication” was defined. The conceptual work has been done to extend the existing modular Inaris HbbTV Solution to meet all these requirements.
Starting work on Media Synchronisation
Multi-stream and inter-device media synchronisation: Within HbbTV 2.0 it is defined how streams delivered via broadcast and via broadband can be synchronised. For example, synchronising audio delivered via broadband to broadcast video for watching a video with soundtracks in other languages. This is now also enabled across devices. Based on the experience gained within the HBB-NEXT, the Inaris HbbTV Solution will be extended for media synchronisation. TARA has started to work on this feature.
Inaris HbbTV using Chromium without CE-HTML
The HbbTV standard requires a browser supporting the CE-HTML standard. As there are very few browsers that support CE-HTML we investigate the possibility of replacing the CE-HTML functionality with a standard HTML-5 rendering engine. For this reason we integrated Chromium in our HbbTV Solution and tested it with available HbbTV applications to find out how much of the CE-HTML features are actually used. We are now identifying the CE-HTML features that are not covered by Chromium and evaluate which can be replaced using standard HTML-5 technology.
23rd HbbTV Interoperability Workshop
TARA Systems participates in the 23rd HbbTV Interoperability Workshop at IRT (Insitiut für Rundfunktechnik) in Munich to meet app developers and manufacturers to test the interoperability of HbbTV terminals and HbbTV applications. This time we present our integration of Chromium in our HbbTV solution in order to investigate if the currently needed CE-HTML functionality can be replaced.
InarisDASH gets HbbTV 2.0 compliant
TARA Systems participates in ANOPAS – a research project for application oriented optimisation of media streaming with MPEG-DASH and extends its MPEG-DASH client InarisDASH with features required by HbbTV 2.0. The project partners are Fraunhofer Fokus and Technische Universität Berlin.
Learn more about ANOPAS
Start of the ANOPAS MPEG-DASH Research Project
The ANOPAS research project has been set-up by the partners TARA Systems, Fraunhofer FOKUS and TU Berlin to develop and evaluate innovative adaptation algorithms for adaptive streaming. The main focus is on the MPEG-DASH streaming protocol since this is widely used in web browsers and with HbbTV services.
ANOPAS aims at reaching the best possible playback quality, fairness between users in multiple user environments, live streaming with low latency and efficient operation in wireless networks. The generated solutions shall be implemented in prototypes and evaluated in realistic test scenarios. This project has received funding from the Bundesministerium für Wirtschaft und Energie (BMWi) and their innovation program »Zentrales Innovationsprogramm Mittelstand« (ZIM).
DASH client solution InarisDASH
MPEG-DASH, a technology that enables adaptive, bandwidth-dependent streaming of media content, is part of the HbbTV 1.5 specification. In order to support this standard with our HbbTV Solution, we have developed our own MPEG-DASH client solution InarisDash.
Developing an interactive, global iTV platform
TARA Systems participates in the Global ITV project, where several European and Brazilian companies, organisations, and research institutions have set themselves the goal of developing an interactive, global iTV platform and achieve the coexistence, interoperability, and convergence of HbbTV and Ginga.
As partners we provide a set-top box prototype based on our Inaris TV Middleware and our Inaris HbbTV Stack.

Semi-automatic Execution of the Official HbbTV Test Suite
Despite our automatic execution, a complete test run of the official HbbTV test suite can take up to four hours, whereby a large number of tests had to be checked manually in real time. Accordingly, an employee was tied up for the entire duration of this.
After the expansion of our test environment in the form of a test manager, the test suite execution and the corresponding human evaluation no longer need to be carried out simultaneously. During the test run, artifacts in the form of records of the screen contents are automatically created, which can be evaluated later on, thereby saving time. The test result is summarised in an automatically generated test report.
