Agreement Signed to Acquire Dibcom
Agreement signed to acquire DiBcom Paris, July 29, 2011 at 8:00 am CET - Parrot, a global leader in wireless devices for mobile phones, is announcing that it has signed an agreement with a view to acquiring 100% of the capital of the French technology company DiBcom, specialized in digital television and radio in particular for the automotive industry. This is particularly strategic for Parrot, which is going to be able to harness unique know-how in the multi-standard digital radio and television field, as well as a broader customer base in the automotive sector. At the same time, the development of a complete solution, incorporating all the technologies developed by both companies, represents a significant competitive advantage and adds further value, particularly on the growing market for infotainment and multimedia car radios. DiBcom designs and markets high-performance integrated chipsets enabling low-power and high mobility digital television and radio reception, for all transmission standards (DVB-T, ISDB-T, ATSC, CMMB, etc.), thanks in particular to a programmable core for signal processing, developed by DiBcom. Founded in 2000, DiBcom has already sold more than 25 million integrated chipsets enabling digital radio television to be received whatever the transmission settings used, in Europe, Asia, Australia, South America and Japan. Its solutions are used for receiving radio and television in handheld multimedia products as well as vehicles, sold worldwide by manufacturers including Audi, BMW, Mercedes, Porsche, Volvo or Garmin. The transaction consists of €15.9 million to purchase share capital and a net debt buyback (initially mainly convertible bonds) for approximately €12 million. -

Latest Transmitter Technology for VHF Band
Broadcasting and audio/video technology | Transmitter systems Latest transmitter technology for VHF band III Radio and television are celebrating a comeback in VHF band III as the UHF band is increasingly dedicated to other applications such as wireless communications. With the R&S®TMV9 medium-power transmitters and the R&S®THV9 high-power transmitters, network operators are now able to use the latest technology in this frequency band, too. Broadcasting in VHF band III is gaining new momentum Terrestrial broadcasting transmitters for UHF bands IV/V have somewhat overshad- owed transmitters for VHF band III over the past few years. That’s changing with the digital dividend, which has brought increased significance to band III for ana- log and digital TV as well as for digital audio broadcasting. This is because regula- tory authorities in many countries have instructed broadcast network operators to release frequencies in the UHF band so that they can be available for other appli- cations such as wireless communications. Free channels in VHF band III can be used for analog and digital TV. In addition, digital audio broadcasting in line with Fig. 1: Liquid-cooled R&S®THV9 high-power the DAB(+) standard will be implemented in this band. DAB(+) networks are being VHF transmitter featuring 5.2 kW output power expanded in some regions, while new, nationwide networks are being built in oth- from four amplifiers. ers. Broadcasting in VHF band III is gaining momentum. To accommodate this transition, Rohde & Schwarz has announced two new com- pact transmitter families that provide network operators with peak values in energy efficiency, power density and flexibility. -

The techniques simultaneously but with a delay to overcome the effects of flat investigated can be applied to standard receiver equipment without modification.

NDS Response to Consultation on Issues Relating to Mobile TV Services
NDS Response to Consultation Paper on Issues Relating to Mobile TV Services Promoting a Level Playing Field NDS believes in and has consistently promoted a level playing field for all types of delivery platform in India – using cable, DTH satellite, IPTV, microwave distribution, powerline, terrestrial, wireless and yet to be developed technologies. NDS welcomes any regulatory development that will facilitate the growth of new free-to- air and pay TV services, provided that the regulatory development will not: • significantly impair the ability of content providers and platform operators to make reasonable returns on their investments, nor • significantly favour one type of service platform or delivery method over the others, or disfavour one compared to the others. NDS recognises that broadcast mobile TV is inherently a different type of service to the other broadcast TV services delivered to “fixed” devices, and that it is at a very early stage of deployment worldwide compared to such services. Broadcast mobile TV is still at a nascent stage, with at least ten delivery technologies1 and fewer than twenty commercially launched services to date. The technology fragmentation is thus far greater than that for either digital television broadcasting or 2G or 3G mobile telephony in their launch phases. Moreover, while DVB-H leads in terms of number of trials and services, the 1seg (ISDB-T), T-DMB and S-DMB technologies are way ahead of DVB-H in terms of usage, delivering mobile TV to over 11.7 million2, 6 million3 and 1.2 million users or subscribers respectively. It thus appears too early to pick winning technologies. -

ECC Report 177
ECC Report 177 Possibilities for Future Terrestrial Delivery of Audio Broadcasting Services April 2012 ECC REPORT 177 – Page 2 0 EXECUTIVE SUMMARY This Report considers the possibilities for continuing Radio Broadcasting into the future. While recognising that technological developments are opening a wide range of potential platforms for the distribution of audio content, it is felt that ‘terrestrial’ distribution with strategically placed transmitters simultaneously serving a large number of independent receivers will continue. This is particularly true for portable and mobile reception. With this in mind, this document concentrates on terrestrial distribution platforms and especially the relevant digital technologies that exist and are being developed. Radio is now very much a medium which can be, and is, accessed by an audience where a large portion is either mobile or doing something else. The motorist is a good example of this. The report looks at how this audience might be served in the future. While, in the past, conventional terrestrial radio broadcasting was the only viable way to serve this audience, technological convergence and changing habits mean that other platforms such as mobile broadband, satellites and wired infrastructures can now be used under the right circumstances. In spite of this, terrestrial broadcasting does offer certain advantages and it is felt that this will continue for the foreseeable future. Terrestrial broadcasting is itself changing with the advent of digital modulation systems. The report goes on to compare and contrast these modulation systems in some detail, looking at the strengths and weaknesses of each one. This is against the background considerations of audience size, geographical concentration and demographics, and how each system is able to exploit the available spectrum.
