We supply and support Pro Audio products for distribution, switching, monitoring, master control, studio production, Audio visual Industry, digital production, broadcasting, and in general for the communication industry.
Broadcasting digitally over traditional radio waves
HD Radio By broadcasting digitally over traditional radio waves, a single frequency is now capable of delivering up to four stations of content in crystal clear sound. All you do is tune in to your favorite station and your HD Radio receiver will automatically lock in to the HD1 signal for that station. One notch over on the dial and you’re listening to entirely new content on the HD2 station. Additionally the digital signal provides on-screen information such as: album art, song info, traffic and weather. It’s time for a smarter radio. HD Radio devices receive a digital signal over traditional radio waves and require no Internet connection or monthly fee. Enjoy HD Radio at home, on road, and on the go. Our receivers are factory installed with top automakers and available from leading electronics brands. Select a category below to find the receiver that’s right for you.
Analog audio is converted into a digital signal
DAB
Digital audio broadcasting (DAB), also known as digital radio and high-definition radio, is audio broadcasting in which analog audio is converted into a digital signal and transmitted on an assigned channel in the AM or (more usually) FM frequency range.Digital audio broadcast signals are transmitted in-band, on-channel (IBOC). Several stations can be carried within the same frequency spectrum. Listeners must have a receiver equipped to handle DAB signals. At the transmitting site, the signal is compressed using MPEG algorithms and modulated using coded orthogonal frequency division multiplexing (COFDM). A digital signal offers several advantages over conventional analog transmission, including improved sound quality, reduced fading and multipath effects, enhanced immunity to weather, noise, and other interference, and expansion of the listener base by increasing the number of stations that can broadcast within a given frequency band.
Openly standardised digital broadcasting system for all broadcasting frequencies
DRM is the universal, openly standardized digital broadcasting system for all broadcasting frequencies, including the AM bands (LW, MW, SW), as well as VHF Bands I, II – (FM band), and III.DRM ensures the efficient and complete digitization of those countries committing to the digital radio roll-out. The great flexibility of DRM supports all types of coverage needs – from local, regional, nation-wide to international. DRM allows a seamless transition to digital radio with the upgrade of existing transmitter infrastructure as well as with analog-digital simulcast configurations. DRM digital radio can save broadcasters up to 80% in energy and maintenance costs.DRM is the universal, openly standardized digital broadcasting system for all broadcasting frequencies, including the AM bands (LW, MW, SW), as well as VHF Bands I, II – (FM band), and III.DRM is greener, clearer, wider, bigger, better quality & audio content.
Disruptive Modulation technique
SVURG/Z-MOD
‘SVURG’ Technology using ‘Z-Mod’ modulation process, is a path breaking Patented invention for communications with “ZERO SIDEBANDS”. SVURG principals used in ‘Z-Mod’ modulation process, challenge the present belief that, “SIDE_BANDS” carry all the information and scientifically establishes that pure Carrier itself (without any side bands) can carry many thousands time more data and information in all forms of communications systems. Z-Mod provides, three distinct major advantages simultaneously: –
- Reduces spectrum needed for communication channel to fraction of 1 Hz, or zero bandwidth.
- Increases data/signal carrying capacity by many thousand time.
- Reduces radiated RF power requirement to 0.01% or less. Or increase area coverage by 10,000 times or more.
Openly standardised digital broadcasting system for all broadcasting frequencies
This proposal is designed to provide maximum utilisation of valuable spectrum and provides nationwide coverage with multiple channels using single frequency network of FM transmitters across the country. This is achievable using latest technological innovations in field of digital Radio. The recommended HD Radio™ system has proven itself as the world’s most popular digital radio system, with millions of radios in the market, and thousands of stations broadcasting round the clock. It’s all real, it’s all proven and it’s both reliable, and cost effective and above all it is available today.
The move from the analog technology of today to the eventual full utilization of the spectrum by digital signals cannot be done overnight, a transitional technology is needed to ease the costs and disruption of the move, while assuring that with each improvement, the public is better served, and transition costs are minimized.
Network of transmitting stations
A Single Frequency Network (SFN)
SFN is a network of transmitting stations that use the same frequency to transmit the same information. A Single Frequency Network is a means to extend the coverage area without the use of additional frequencies. This multipath immunity can be used to build an SFN with an overlapping network of transmitter stations that use the same frequency. In the areas of overlap, the weaker of the two signals is considered as an echo due to multipath reception. However, the echo has to fall within the guard interval and the stations must be synchronized. Hence, if two stations are far apart, the time delay between the two signals can be large and the system will need a large guard interval.
Global solutions on key issues for its member unions
It was established in 1992 as a coordinating body at the international broadcasting level. Since then, the WBU has provided global solutions on key issues for its member unions. The North American Broadcasters Association (NABA) acts as secretariat for the WBU.The broadcasting unions who belong to the WBU are the Asia-Pacific Broadcasting Union (ABU), the Arab States Broadcasting Union (ASBU), the African Union of Broadcasting (AUB), the Caribbean Broadcasting Union (CBU), the European Broadcasting Union (EBU), the International Association of Broadcasting (IAB/AIR), and the North American Broadcasters Association (NABA).
