Operator Applications (OpApps)

HbbTV OpApp Specification Update

The updated HbbTV OpApp specification improves support for operator applications to render IP-delivered linear channels, including enabling regular HbbTV interactive (“red button”) applications to appear alongside IP-delivered linear channels and operator-managed user interface elements. It allows for a consistent and seamless viewer experience across broadcast and IP-delivered linear channels.

The updated specification also allows an operator application to manage the streaming and presentation of a collection of IP-delivered linear channels discovered from a DVB-I service list or equivalent, enabling consistent flexible streaming approaches and fast channel change times.

The updated specification also includes improvements identified during the development and rollout of operator applications in Germany where they have been commercially deployed since March 2019.

OpApps Specification TS 103 606 V1.1.1 (2018-05)

This specification is an extension to the core HbbTV specification to support operator application. Operator applications allow TV operators, in partnership with TV manufacturers, to provide an operator-branded experience as an application on TVs. This application acts as a “Virtual Set Top Box”, providing effectively all functionality of a Set Top Box (STB) without the need to install one. The OpApp specification describes how the HbbTV browser can run both HbbTV broadcaster applications and operator applications at the same time. It specifies how operator applications are discovered, installed and how they can replace the TV’s native UI, including access to the TV’s remote control key. New readers should read “OpApps Explained” first in order to get an overview.

Testing Information and Support

HbbTV Test Suite

The HbbTV Test Suite provides a set of test material to enable implementers to test receivers against the HbbTV specifications and other associated specifications (such as OIPF). It is suitable for suppliers of complete receivers and also suppliers of hardware and software components.

There are 3 releases each year of the HbbTV Test Suite, -1, -2 and -3.

-1 is when most changes are expected and is not to be used for certification. New tests can be added in this release.
-2 is the most important of the year and is intended for certifying devices entering the market the following year. New tests can be added in this release.
-3 fixes bugs and no new tests can be added in this release. It can also be used for certifying devices entering the market in the following year.

Currently the Test Suite includes tests for ETSI Specifications ETSI TS 102 796 v1.1.1, v1.2.1, v.1.4.1 (which includes v1.3.1) and Tests for HbbTV Specification v.2.0.2.

Anyone can access the HbbTV Test Suite through an HbbTV Registered Test Center. A list of these can be found in the following section.

HbbTV members who have the necessary expertise and equipment may also license the test suite for use in their own facility. The test suite license covers a whole company, including associated companies, and a list of those who have signed it can be found here. The test suite is distributed with details on how to obtain a new test harness which provides minimum required functionality to execute approved test materials in a manual way. Commercial test tools which implement the test harness specification are also available.

This file contains an indication of the contents of the test suite. The precise contents at any particular time may differ due to tests being removed and/or reinstated through the Test Material Challenge Process.

Additionally, as explained in this Presentation HbbTV also publishes a list of only the approved core HbbTV Test Suite coverage in the “HbbTV Test Assertion Specification”.

The precise contents of these lists at any particular time may differ due to tests being removed and/or reinstated through the Test Material Challenge Process. In case of any conflict, the list in the Test Assertion Specification takes precedence.

HbbTV Members wishing to license the HbbTV Test Suite should leave contact details here:

    HbbTV Test Repository

    • HbbTV Test Review

      HbbTV welcomes test reviewers to help qualify whether submitted test material is fit to be included in an official Test Suite.

      HbbTV and OIPF test material is collected and tracked in a common HbbTV Test Repository powered by SVN.  The test material is not for testing or validating devices and such use is prohibited. The HbbTV Test Suite is provided for testing devices against the HbbTV specification and the OIPF test suite is provided for testing devices against the OIPF specification.

      During the “Test Review” process, any issues found with submitted test materials are tracked using Redmine. HbbTV and OIPF have anticipated that issues may be encountered even after an official Test Suite is released, and a “Test Material Challenge Process” exists, again tracked by Redmine.

    • Who can be a Test Reviewer?

      The process for developing and reviewing test materials is shared by two standards bodies, namely HbbTV and the Open IPTV Forum, since test specifications have significant overlap. A test reviewer can be a member of either body (or both), a subcontractor of said member or an approved test material provider.
      The details of how test material is reviewed and approved, as well as how test reviewers are selected for particular tests is given in the Test Material Approval Procedure document which is available to companies that become test reviewers.

    • How to become a Test Reviewer

      In order to become a test reviewer, your company will need to conclude the Test Repository Access Agreement (TRAA). To start this process, please send an e-mail to info@hbbtv.org, clearly stating your company wishes to get access to the HbbTV Test Repository.
      In case your company is a member of HbbTV and/or OIPF, please clearly state this in the e-mail. Please note that such membership will be checked as part of the application procedure.

      After the TRAA is signed, individual user accounts will be created to obtain access to the SVN Test Repository and the Redmine issue tracker.

    • Getting access to the SVN Test Repository

      Access to the HbbTV test repository will first be approved per company. Presently only one SVN account per member company is permitted, however multiple individuals at that member company can use SVN with that account.

      To request access to SVN send an email to support@hbbtv.org stating the name of the member company and the email that you would like the SVN account invitation email to be sent to. This invite will give you a link to complete your account creation.

      Further details on how to connect to the repo will be given following a successful account creation

    • Getting access to the Redmine Issue tracker

      If you do not have an account on the Redmine server, you can register for one by going to the following URL: https://redmine.hbbtv.org/account/register

      When registering with Redmine, as with the email lists, please only use email addresses clearly linked to your company details given in the TRAA application questionnaire. Yahoo, Google, Hotmail or e-mail addresses that have no company affiliation are not acceptable.

      When you have registered with Redmine, your account will be activated manually by the Redmine administrator. In case you have any questions around your account please contact support@hbbtv.org.

    Security

    HbbTV takes security very seriously. Security researchers who wish to disclose vulnerability in an HbbTV specification should contact info@hbbtv.org in order to enable a constructive engagement. Vulnerabilities associated with a specific manufacturer’s implementation of HbbTV should be reported to the manufacturer concerned but HbbTV can assist in facilitating this.

    Tampering with the broadcast transmissions is currently an area of interest for security researchers. Whilst HbbTV does not define the specifications for broadcast transmission, we take this topic very seriously and work actively with the other standards organisations responsible such as the DVB project on such matters, as well as making revisions to our own specifications to protect users. Further relevant Information.

    HbbTV Association Policy on Trust and Security

    The HbbTV Association is committed to improving the security of services provided using HbbTV technology. The following policy guides HbbTV’s work:

    • HbbTV will create a comprehensive set of specifications and guidelines that addresses security threats relevant to HbbTV. As new security threats appear, the HbbTV specifications will adopt countermeasures to these.
    • The HbbTV Association in itself cannot act as a guarantor for the security of HbbTV services used in any given market as the security of any HbbTV deployment is reliant on the correct implementation of the HbbTV specifications (across the value chain from content provider to CE manufacturer) plus other elements of general internet and broadcast security that are outside the scope of the HbbTV specifications.
      This means that, whilst it is entirely possible to build an end-to-end system based on HbbTV that consumers can use safely (e.g. for commercial transactions), neither the HbbTV Association nor its specifications can be the sole factor in determining the integrity of HbbTV deployments.

    Interoperability Tools

    In this section you will find more detailed information for supporting HbbTV implementers. The section will be updated on a regular basis.

    • HbbTV DASH DRM Reference Application

      The presentation HbbTV DASH DRM Reference Application Explained provides an overview of the features and how to use the HbbTV DASH DRM Reference Application.

      The code and documentation is available at https://github.com/HbbTV-Association/ReferenceApplication.

      Further information about production and staging instances can be found here:

      http://refapp.hbbtv.org/production

      • Updated in line with Test Suite, 3 times a year
      • HbbTV 2.0.1 and 1.5 Playready and Marlin DRM streams
        • Also non-DRM streams for reference and including MSE/EME for non HbbTV browsers
      • Subtitle and audio stream selection via color buttons
      • Live and VOD DASH profiles

      http://refapp.hbbtv.org/staging

      • Intended for early access testing of new features

      The HbbTV DASH DRM Reference Application – developed by Sofia Digital – was commissioned to aid interoperability of applications and devices. The application, and sample content, showcase HbbTV technology and help members in validating their tools, content and devices.

      The reference application is freely distributed under an open source MIT licence and can to be used by HbbTV Members as well as non-Members.

      Project deliverables also include documentation covering the creation of valid MPEG-DASH files from users’ own video content. Furthermore, the reference application is implemented in a way which makes the code easily reusable for anybody to implement their own DASH video streaming application.

      The HbbTV DASH DRM Application can run on both new HbbTV terminals entering the market and on a large proportion of the installed base of HbbTV terminals and, optionally, on web browsers on non-TV related devices; it presents a catalogue of reference content items to be played back in clear unencrypted format or with each supported DRM system. The application and the content catalogue is designed in a way that it can be easily extended with additional content and DRM systems. Furthermore, the application is written in such a way it allows an application author to determine the structure and purpose of each functional area allowing them to easily understand the code and to “pick & choose” which parts of the application to copy.

      As well as running on HbbTV 1.5 and 2.0.1 terminals, the reference application runs on web browsers supporting W3C MSE and EME.

      The presentation above provides an overview of the features and how to use the HbbTV DASH DRM Reference Application.

    • HbbTV/DVB DASH Content Validation Tool

      The presentation “DVB-HbbTV DASH Validation Tool_explained“ provides an overview of the features and how to use the DASH Validation Tool.

      The DASH validator source code is available and free under an open source license at https://github.com/Dash-Industry-Forum/Conformance-Software. Users can easily validate their content through the web-based interface or build a local copy for use in a production workflow within their own environment.

      The DASH Validation Tool extends the current DASH-IF validator found at https://conformance.dashif.org to complement the HbbTV Association DRM Reference Application and Test Suite.

      The specifications against which conformance is performed include:

      • MPEG-DASH ISO/IEC 23009-1
      • ISO BMFF ISO/IEC 14496-12
      • DASH-IF IOP 4.1
      • CMAF ISO/IEC 23000-19

      • DVB MPEG DASH Profile v1.1.1
      • HbbTV 1.5 Specification

      Checks include:

      • MPEG-DASH MPD validation (XML, DASH schema, and MPEG-DASH MPD rules)
      • Segment Validation (ISO BMFF and MPEG-DASH segment rules)
      • Cross-representation validation (MPEG-DASH cross-representation rules)
      • Live MPD segment access validation
      • Above items for above mentioned specifications

      Note: The checks are done till the ISO BMFF level (no checks on track media level)

    • HbbTV Developer Portal

      This portal aims at offering a clear understanding – with examples, guidelines, specification references and available resources – of the programming additions required by the HbbTV specification to manage and to programme specific TV related features such as, for example, an application launch and its lifecycle, its signalisation on delivery means, the remote control interaction, handling of the broadcast a/v object etc.
