  • UK Capital To Begin HD Terrestrial Tests


    London’s Crystal Palace transmitter has been fitted with equipment necessary for high definition test transmissions to be carried out.

    The modulator equipped for test transmissions using the new DVB-T2 transmission standard was provided by Enensys.

    DVB-T2 high definition tests are scheduled to begin later this month.

    Last September, the BBC successfully performed test transmissions in the UK to receive high def pictures compliant to the DVB-T2 standard using a real-time demodulator.

    It was the first time anywhere in the world that a live end-to-end DVB-T2 chain was demonstrated.

    The UK’s analog transmission ends in 2012 but some parts of the country will get the benefit of DVB-T2 as early as this year.

    The current estimate is that in 2009 there will be three HD channels available in the UK, one of which goes to the BBC and the other two going to ITV, Channel 4 or Five.

    According to DigitalSpy, those broadcasters who plan to launch HD services on multiplex B, which is being reconfigured across the UK in tandem with switchover to support HD broadcasts, will take part in the trials.

    Others taking part include transmission infrastructure provider Arqiva and set top box manufacturers Panasonic, Pace, Humax and Sony.

    Ofcom will chair a steering committee overseeing the trials.

  • DiBcom Launches Programmable Mobile TV Solution


    DiBcom is to launch a new platform that offers device manufacturers a solution to the problem of multiple standards worldwide for fixed and mobile TV.

    Known as Octopus, the platform is based on a programmable architecture that enables one design to be seamlessly and cost-effectively targeted at many existing and upcoming mobile TV standards.

    DiBcom said the first commercialised version is fully compliant with the most widely deployed standards today: CMMB, DVB-T, DVB-H, DVB-SH, ISDB-T (1SEG & Full-SEG) and T-DMB. Other emerging standards such as ATSC M/H, DVB-T2, and any others, will follow.

    Khaled Maalej, CTO of DiBcom, said existing multi-standard components combine the circuitry of some standards in one chip with minimum optimisation.

    He said Octopus, however, is based on one programmable, broadcast specific, vector signal processor (VSP) and is able to handle any standard by adapting its microcode.

    The VSP engine is integrated with a multi-mode channel decoder and MAC, memory and a power management unit (PMU), therefore offering optimal power consumption for each standard.

    Manufactured using 65nm technology, the Octupus platform comes with a multi-band RF tuner in two package options, and in either single or diversity (dual-antenna) configurations.

    DiBcom said the advantages offered by the new platform include:

    • A universal and cost-effective architecture ideal for a one-to-many strategy (all regions, all applications addressed with one device)
    • High performance at low power consumption in all functional modes
    • An integrated PMU for a simpler system design (one voltage input), efficient power consumption and longer battery life
    • No unnecessary hardware duplication or reliance on powerful CPU’s as required by other multi-standard solutions
    • Embedded descramblers for all conditional access (CAS) protected content

    Possible applications for the Octopus platform include the automotive, PC/notebook, PMP, PND, mobile phone as well as LCD TV and Set-Top-Box market sectors.

    Yannick Levy, CEO of DiBcom, said handset manufacturers now had the opportunity to increase their volumes of mobile TV terminals based on the Octopus platform since they can ship them to any region in the world by simply loading the appropriate software.

    "Availability of a large choice of terminals is a major market enabler," he said.

    Octopus component samples will be available in early Q2 2009.

  • BBC to launch regular HD DTT broadcasts


    Catherine Smadja, head of strategy at the BBC, said the Corporation is to start regular DVB-T2 HD broadcasts in November 2009.

    Speaking at the the International Broadcasting Convention (IBC) 2008 in Amsterdam, she said: “One of the multiplexes will be upgraded to DVB-T2 and MPEG-4, on which there will be the BBC HD service and two others. And very soon thereafter, three other HD services.”

    The new multiplex will launch in November 2009 in the first regions, but should eventually be available to 98.5 per cent of the UK population.

    Five other DTT muxes will remain DVB-T.

    “DVB-T2 is for us an absolute necessity, because DTT is the number one platform in the UK,” Smadja said.
    “We have to offer HD as a public service broadcaster on DTT, not only on cable and DTH.

    Smadja said there was no business model for how to accomplish this and HD would only add to the cost.

    “There might develop a market for HD pay-TV, but not for free-to-air,” she said. “Luckily, the DVB Group solved the spectrum scarcity problem.”

  • Set-top Box Capable of HD Content Over DVB-T2


    Pace plc, a developer of digital TV technologies, has made the first set-top box capable of receiving and displaying DVB-T2 HD content.

    The prototype consists of the world’s first DVB-T2 front-end (the silicon tuner TDA18211 and a prototype of the forthcoming demodulator TDA10055) from NXP Semiconductors and a Pace high definition terrestrial set-top box.

    It will receive a live MPEG-4 HD stream from an Enensys DVB-T2 Modulator based at the DVB (Digital Video Broadcasting) stand at the IBC 2008 show in Amsterdam, which begins on Friday.

    DVB-T2 brings efficiencies of between 30-50 per cent in its use of spectrum compared to DVB-T and is expected to be a key enabler to the roll out of high definition TV in the UK over Freeview.

    Earlier this month, the BBC succesfully received high def pictures compliant to the DVB-T2 standard using a real-time demodulator during test transmissions.

    As a set-top box developer, Pace has been involved in the creation of the DVB-T2 draft standard, focusing on key technical aspects that add to the improvement and robustness of the standard, which was only confirmed in June this year.

    Darren Fawcett, chief technologist for Wireless Systems at Pace plc said the take up of high definition services within mature TV markets was picking up speed.

    He said it was expected to grow substantially over the next five years. “But this HD content is currently in the cable and satellite domains,” he said.

    “To enable terrestrial services to compete effectively with the other platforms, DVB-T2 is an essential move.

    “As we saw with the shift to the DVB-S2 standard for satellite services, the extra efficiencies in the use of the spectrum will make the option of delivering HD via DTT viable.”

    With DVB-T2 the DVB Project offers broadcasters a means of using that spectrum in the most efficient ways possible using state of the art technology.

    The first country to deploy DVB-T2 is likely to be the UK, where ASO is already under way.

    The regulator there, Ofcom, has stated its intention to convert one nationwide multiplex to DVB-T2 with the first transmissions of multichannel HDTV set to begin at the end of 2009.

    Test transmissions began immediately after the approval of the standard in June 2008.

  • HD test success spells bandwidth boost

    BBC succeeds with world’s first reception of HD pictures over DTT using DVB-T2

    Test transmissions in the UK have successfully received high def pictures compliant to the DVB-T2 standard using a real-time demodulator.

    The BBC, which performed the tests, says this is the first time anywhere in the world that a live end-to-end DVB-T2 chain has been demonstrated.

    DVB-T2 is a new version of the DVB-T standard currently used for digital terrestrial television in the UK.

    It offers an increase in efficiency over DVB-T, which means more bandwidth will be available on the multiplex when it is reconfigured in tandem with digital switchover to permit the carriage of high definition services.

    That, combined with a switch from MPEG-2 to MPEG-4, will allow for increased HD content.

    The UK’s analogue transmission ends in 2012 but some parts of the country will get the benefit of DVB-T2 earlier, with a few places going live next year.

    The current estimate is that in 2009 there will be three HD channels available in the UK, one of which goes to the BBC and the other two going to ITV, Channel 4 or Five.

    The BBC started DVB-T2 test transmissions from the Guildford transmitter in June.

    Justin Mitchell, leader of the BBC’s DVB-T2 modem development team, said: “Following the approval of DVB-T2 in June and the launch of test transmissions from Guildford transmitter the next day, we are delighted that on Kingswood Warren’s 60th anniversary our team has been able to deliver a working demonstration of a DVB-T2 modulator and demodulator.”

    The modulation and demodulation devices will be made available for licensing.

    There will be a demonstration of the DVB-T2 modulator and demodulator on the DVB stand 1.D81 at IBC in Amsterdam.

  • Olympics and Tour de France to be aired as Europe's public channels add to their high definition options


    The UK’s BBC has begun testing the transmission of high def services over Freeview in a move that could see the introduction of full HD terrestrial by the end of 2009.
    The broadcaster has started transmissions from a Guildford-based transmitter using the second-generation DVB-T specification DVB-T2.
    Justin Mitchell, leader of the DVB-T2 modem development team at the BBC, said the trial could enable the introduction of HD onto Freeview by December next year.
    DVB-T2 is said to offer 30 per cent more data carrying capacity as DVB-T under the same conditions.
    Across the Channel, the HD version of public channel France 2 has been launched on several platforms, including CanalSat DTH and Numéricable.
    As has been the case with other broadcasters across Europe, including VRT in Belgium and Nederland 1 in The Netherlands, France 2 will show sport events such as the Tour de France and the Beijing Olympics in HD.
    Freeview currently uses the ten-year old DVB-T standard. DVB-T2 was developed for use in a “post-Analogue Switch-Off environment”.
    UK communications regulator Ofcom has said it wants to convert at least one of the nation’s DVB-T multiplexes to DVB-T2 by the end of 2009.
    The test comes as HDTV services begin to flourish in the UK, which has almost 10m HDTV sets currently in use.
    While Sky – the main provider of HD broadcasts in the UK – has barely half a million subscribers signed up to its Sky HD service, much is being made of the May launch of Freesat.
    The venture – a joint initiative between the BBC and ITV – has the potential to give millions of UK viewers access to free HD programmes for the first time.
    Its launch has prompted Sky to cut the price of its Sky+ HD set-top box by 50 per cent.
    Virgin and Apple have also improved their HD offerings recently.
