Frequently asked questions about HbbTV 2.0.
This is a version of TS 102 796 V1.2.1 with the changes from errata 4 (see below) applied. Changes are marked with the usual underline/strike-through convention to make it easier for users to see the differences. Issue numbers are included for cross-referencing with errata 4.
TS 102 796 V1.2.1 (often called HbbTV 1.5) introduced support for HTTP adaptive streaming (based on MPEG-DASH), improving the perceived quality of video presentation on busy or slow Internet connections. It also enabled content providers to protect DASH delivered content with potentially multiple DRM technologies based on the MPEG CENC specification, improving efficiency in markets where more than one DRM technology will be used.
This version was based on 3 documents;
This errata document contains a set of identified and resolved errata to the HbbTV specification published as ETSI TS 102 796 v1.2.1. This document contains all agreed errata and replaces errata 3, errata 2 and errata 1.
This is the third errata to TS 102 796 1.2.1. It is replaced by errata 4 and is preserved here purely for the record. It should not be used.
This is the second errata to TS 102 796 1.2.1. It is replaced by errata 4 and is preserved here purely for the record. It should not be used.
This is the first errata to TS 102 796 1.2.1. It is replaced by errata 4 and is preserved here purely for the record and should not be used.
This is an updated version of the stand-alone HbbTV 1.5 specification. It is preserved here purely as for the record. It is obsolete and should not be used any longer as the content is included in TS 102 796 V1.2.1 with important clarifications.
This is the original version of HbbTV 1.5. It is preserved here purely as for the record. It is obsolete and should not be used any longer as the August 1st 2012 version includes important clarifications.
This is the original HbbTV specification. It should only be used when developing applications and services targeted at already deployed HbbTV TVs and set-top boxes. New TV and set-top box developments should use TS 102 796 V1.2.1 or HbbTV 2.0.
This errata document contains a set of identified and resolved errata to the HbbTV specification. These have been integrated with HbbTV 1.5 and the text of ETSI TS 102 796 V1.1.1 and the results are included in version 1.2.1. This fully replaces the former errata 1.
This is errata 1 for HbbTV 1.0. It is preserved here purely as for the record. It is obsolete and should not be used any longer.
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.
This presentation provides an insight into the HbbTV OpApp specification. It includes a description of what an operator application is, market drivers for operator applications, as well as an overview of technical details within the HbbTV OpApp specification.
HbbTV has ordered unit tests for the operator applications specification. More than 300 of these have been delivered but they are in the process of being reviewed and are NOT YET approved for certification. HbbTV welcomes support from interested parties to contribute to the review and approval process, please contact firstname.lastname@example.org.
The versions of the HbbTV Specification published to date rely on signalling in the broadcast to start broadcast-related applications, through the Application Information Table (AIT). This document defines a method for discovery of broadcast-related HbbTV services via a broadband internet connection for settings where AIT signalling via the broadcast network is not available to the HbbTV terminal.
This specification defines how HbbTV terminals can be used with IPTV services. It is applicable to IP-only devices (no DVB-C/S/T tuner) where the broadcast” is IPTV. It is also applicable to hybrid devices where some TV channels come via IP and some via DVB-C/S/T.
The document contains the list of TLS root certificates that must be supported by HbbTV terminals.
This spreadsheet replaces a list included in HbbTV 1.0/TS 102 796 V1.1.1.
The contents of this spreadsheet were developed by the UK Digital TV Group whose contribution is very much appreciated by HbbTV.

In June 2014, the activities of the Open IPTV Forum (OIPF) were transferred to the HbbTV Association. This broadened the HbbTV Association’s mandate to include defining specifications for service providers and technology suppliers that streamline and accelerate deployment of IPTV services.
The HbbTV Test Suite provides a set of test material to enable implementers to test devices against the HbbTV specifications and other associated specifications (such as OIPF). It is suitable for suppliers of complete devices and also suppliers of hardware and software components.
Currently the test suite includes tests for ETSI Specifications ETSI TS 102 796 v1.1.1, v1.2.1 and v.1.4.1 (which includes v1.3.1). Tests for HbbTV Specification v.2.0.2 are expected to be added during H2 2018.
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.
HbbTV Members wishing to license the HbbTV Test Suite should leave contact details here:
HbbTV Registered Test Centers offer HbbTV testing services to the market, for those manufacturers, operators or integrators who do not wish to do HbbTV receiver testing in-house. The process for a test center to register with HbbTV is lightweight with relatively few obligations, in return for which the test center can be added to the list below.
Manufacturers do not need to become an HbbTV Registered Test Center if they are only testing their own HbbTV products.

HbbTV cannot recommend a particular test center nor does it audit or accredit test centers for regulatory compliance. The following criteria may be considered when selecting a test center. It does not include other criteria covering any commercial relationship that would required with the test center.
|Reputation||Is the organisation impartial and trusted in the industry? For example you may wish to request references or evidence of previous relevant work.|
|Technical Expertise||Does the test center employ testers with HbbTV knowledge; and appropriate qualifications?|
|Confidentiality||How does the test center ensure confidentiality of test reports and test samples?|
|Efficiency||Does the test center have good procedures for managing bookings and conduct testing efficiently and quickly?|
|Responsiveness||How will the test center provide swift support and answer questions in a timely manner?|
|Facilities||Does the test center have all necessary equipment to perform the range of testing required?|
|Awareness||How does the test center track changes in published specifications and test suite releases? A list of the approved tests is published above; are they using the latest version of the test suite?|
|Deliverability||Ask for an example test report, to determine if this meets the requirements of the client and any 3rd party regulatory body. Can this report be verified for authenticity?|
|Support||Will the test center assist in debugging any test failures? What is their re-test policy? Will they help with challenging any tests that are felt to be in error?|

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.
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.
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 email@example.com, 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.
Access to the HbbTV test repository will first be approved per company, before individuals can be added. Each individual requiring access to SVN must send a username and password in a single password file created with the htpasswd command to firstname.lastname@example.org.
htpasswd -c myhtpasswd.txt myusername
Please use as username something which allows others to quickly see who you are e.g. simply use “jdoe” if your name is John Doe. On most Unix systems the htpasswd command is available. Windows users will find multiple places to download it when searching via Google.
The SVN repository is located at https://www.hbbtv.org/testing-repo so to checkout the repository the following command can be used.
svn co https://www.hbbtv.org/testing-repo –username=jdoe
If you do not have an account on the Redmine server, you can register for one by going to the following URL: https://hbbtv.fvdev.ca/redmine/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 email@example.com.

HbbTV takes security very seriously. Security researchers who wish to disclose vulnerability in an HbbTV specification should contact firstname.lastname@example.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.

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:
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.
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:
Additionally, the DVB-HbbTV Conformance extensions are:
Note: The checks are done till the ISO BMFF level (no checks on track media level)
