  • What is Freeview (the brand)?

     

    Launched in 2002, Freeview is the digital terrestrial platform (DTT) in the UK, available to virtually all homes across the UK via an aerial. Freeview offers viewers more than 50 subscription-free TV, radio and interactive services on DTT. It is managed by DTV Services Ltd, a company owned and run by its five shareholders (BBC, BskyB, ITV, Channel 4 and Arqiva).

     

  • Who is responsible for the Freeview brand and how do I get it?

     

    First you’ll need to demonstrate that your product meets the standard required by the Freeview trade mark license (TML).


    DTG Testing Ltd offer conformance test services for Freeview and can complete the tests quickly and cost-effectively. Products that successfully pass the conformance tests will be issued with a DTG Test report which needs to be sent to Freeview along with the TML request and supporting documentation.

  • What are the UK specific technical requirements?

     

    The UK specific technical requirements are all set out in the D-Book. The D-Book brings together all of the technical specifications and requirements needed to build a DTT receiver for the UK market. The first place to look is Chapter 22 titled the ‘Receiver Recommendations’.

  • What is the difference between pre-conformance and conformance and who is involved with each?

     

    DTG Testing Ltd provides the conformance testing to check that your product meets the requirements of the Freeview HD and Freeview Play Trade Mark Licenses. 

     

    DTG Testing Ltd offers a range of DTG test suites to help manufacturers carry out their own pre-conformance tests. DTG test suites come with comprehensive training and engineering support.

  • Can we self-certify?

     

    Although manufacturers can self test subject to certain conditions DTG Testing finds that it can be very helpful to manufacturers to have a completely independent test carried out on their products. This approach gives manufacturers the best possible chance of preventing future interoperability issues.

     

    For Freeview Play, some self-certifying is allowed, please contact Freeview ( mike.jones@freeview.co.uk ) for further clarification.

  • We are an ODM for brand name companies. Should it be us or the brand who applies to DTG Testing?

     

    This will depend on the contract signed between the ODM and the end-customer (brand name company). 

     

    DTG Testing usually receives requests from the companies which are directly involved in ensuring the platform is compliant with all the relevant requirements, as set out. This could range from the middleware supplier to the end-integrator. 


    For more information contact: customerservices@dtg.org.uk


  • Can I buy test streams?

     

    All test streams used for testing are available for purchase. Please contact customerservices@dtg.org.uk with a list of requirements and we will supply a quote. 

  • How long does a manufacturer have from when a new version of the D-Book is released to when it's mandatory to implement the new functionality in receivers?

     

    In general, all features introduced in a new version of the D-Book become mandatory for all SD/HD products 12 months after publication. However, the relevant TML documents should be consulted for mandatory dates.

Membership

  • How much does it cost to join the DTG?

    Prior to launch the DTG will help you make all the necessary connections in the UK TV market, including retail, channels and IP service providers, and after launch will provide ongoing technical and business support.

  • What is the process for joining and the licensing terms?

     

    Joining the DTG is easy and our membership team will help you every step of the way.

Test Suites

  • What test suites do you licence?

     

    Full information is available on the Buy a test suite page. 

  • If I encounter a problem with the test streams or I have a question directly related to test streams what should I do?

     

    Problems with test streams should be entered into the DTG Testing squish project at https://www.squishlist.com/.

  • What does it mean if I am unable to access a particular folder on the DTG FTP?

     

    This usually means that you do not have the licence for that particular test suite. To get a quote or to purchase a test suite please email: customerservices@dtg.org.uk.

  • What is the difference between Freeview+ and Freeview+ HD test suites?

     

    Freeview+ and Freeview+HD is sold as one test suite. It is a single test suite that tests receiver recording functionality for both SD (Freeview+) and HD (Freeview+HD) as defined in the D-Book.

  • What test suites does DTG Testing supply for Freeview New Zealand testing?

     

    DTG Testing supplies SI, MHEG, PVR and MHEG HD extensions test suites for Freeview New Zealand testing. 

  • What test suites does DTG Testing supply for Freeview Australia testing?

     

    DTG Testing supplies PVR and MHEG test suites for Freeview Australia. For any other tests suites please contact Freeview Australia directly. Also note that DTG Testing does not perform any Freeview Australia conformance testing. 

Testing Requirements

  • How long does testing take?

     

    Please contact customer services for details and prices.

  • What are the drivers for DVB-T2 adoption in the United Kingdom?

     

    DVB-T2 is already widely adopted in the UK and is radiated from all DTT main station and relay transmitters. DVB-T2 is used to carry HD H.264 content, and the motivation for buying a DVB-T2 capable receiver is the ability to receive HD content.

     

    The HD channels that are currently available are described on the Freeview website here:- http://www.freeview.co.uk/what-we-offer/freeview-hd

     

    Five more HD channels will be launching soon (using DVB-T2), with test transmissions already happening in London. The news of this new HD launch is here:- http://www.bbc.co.uk/mediacentre/latestnews/2013/bbchdchannels.html

     

  • Do you have a technology roadmap for the next three years?

     

    Refer to ‘shaping the future’ timeline

  • What are the pass criteria for RF testing?

     

    Chapter 10 of the D-Book gives detailed information on the tests performed, and the performance targets recommended for receivers intended for use with DVB-T and DVB-T2. 


    The performance tests are broadly split into three categories: basic RF Tests, multipath tests and impulsive interference tests.


    For DVB-T2, all Single PLP (SPLP) and Multiple PLP(MPLP) modes, as specified in the D-Book, are also tested for functional compliance.

     

  • When can you test my product?

     

    Lead times for product testing vary, and we encourage manufacturers to book slots as far in advance as possible. Most manufacturers book product tests approximately two months prior to the required testing date. 

     

    Manufacturers are also encouraged to reserve a retest slot when booking a test.

  • We have one platform for multiple customers (various brands), would a single test be sufficient for all models of the same series?

     

    Yes, ODM suppliers can have their platform tested and certified. These test results can be used by all end-user companies to obtain their certificates as long as the receiver meets the chassis criteria outlined below. 


    However, each company will need to make separate applications for each individual model to both Digital UK and Freeview, for the grant of the appropriate licences.

     

  • Our new receiver is based on one that is already conformant. What do you need to retest?

     

    We determine that a previous test will cover a new receiver if:


    ·         The SI code is unchanged to the model previously tested (including AFDs and Subtitles)

     

    ·         The MHEG Engine is identical

     

    ·         The RF section, including tuner and demodulator hardware is unchanged

     

    ·         The new receiver has at least the same amount of memory available to the MHEG engine as the previously tested model

  • Can you do one-off and ad-hoc tests? How much are they and how long do they take?

     

    We can do reduced coverage testing. The duration and cost will be quoted when you apply, based on the tests to be covered.
