Internet Radio Systems

The internet has made radio truly global. As well as a variety of music stations – from Ambient Trance to Zydeco – users can enjoy chat, entertainment, game shows and plays, all from a tiny digital radio. As listeners realise the potential of internet radio, the options and quality improve. While you can access Internet Radio online, through streaming, this method is often tedious and unreliable, especially if you’re sharing your internet connection. Older people, often fans of what is now niche music, can enjoy their fave tunes, instead of the RnB and excitable DJs that characterise contemporary radio stations. And younger people can access a much more interesting selection than the mainstream, sponsored music permeating the top charts.

At Rococo, there are Internet Radio options for all budgets. The Q2 is an affordable radio, costing only £90. It has simple, funky, retro styling in a range of fun colours, in soft touch finish. You start by hooking it up to your PC or Mac and choosing your favourite 3 or 4 radio stations. These radios are battery operated, with a lifespan of 14 hours (and of course has a mains adaptor and USB cable) ensuring portability and ease of use. You can change your radio stations at any time by connecting to your computer and picking new ones. Adjusting the volume is super easy – all you need do is tilt the front upwards, and tilt forward to reduce the sound. You change radio stations by tipping the device one of four ways, and you switch it off by putting it on it’s front.

The Tivoli Networks Internet Radio system is a more premium option, but is a solid, attractive piece of kit in a furniture style wood cabinet, and can access thousands of radio channels across the world. The radio is perfect by your bedside, as it includes a digital clock and an alarm with sleep timer and snooze function. You can search by country, genre or call letter, as well as streaming music directly from your computer. WIFI connection (with a super buffer) makes it super easy and convenient to use. You can also use a USB input to hook up with your MP3 player. It comes with free UK delivery, and costs just £450.

 

Whatever your needs and budget we can help you achieve your digital dreams either in your home or office. Our many years in business have allowed us to recommend only the very best and most reliable products, satisfying the most discriminating customers. Based on your needs, we will arrange the design of your system, whether it’s an independent single-room installation or a whole house project requiring the integration of several technologies.

The Basics of Satellite Radio Systems

The Basics of Satellite Radio Systems

Satellite radio systems are the consumer’s access to space-based audio technology, offering uncensored, commercial-free programming that comes in crystal clear no matter where you are. But how do they actually work?

The most basic explanation is as follows: programming is transmitted to a communications space satellite, which beams a digital signal back to earth. The signal is encrypted, so it can only be picked up by special proprietary equipment. The signal can be broadcast across more than 22,000 miles and received by the end user with absolutely no degradation in clarity or sound quality.

But the basics are only a small part of what makes satellite radio systems work. Many innovations and the use of cutting-edge communications technology have brought digital radio a long way from where it began just over a decade ago.

Digital radio was actually operating in the early 1990s, with Washington-based Worldspace Corp. providing fixed-location satellite radio to Europe, Asia, and parts of Africa. However the technology didn’t take off in the US until 1992, when the Federal Communications Commission established the Digital Audio Radio Service (DARS) which allocated certain segments of radio frequency for satellite broadcast.

Two companies bid for and won licences to broadcast in the allotted frequencies: American Mobile Radio, which later become XM Radio, paid million for licensing, and Sirius Satellite Radio forerunner CD Radio paid million. XM made it’s nationwide debut in 2001, and Sirius followed in 2002.

Though both companies offer more than 100 channels of commercial-free programming that’s available anywhere in the US, they took different technological routes to achieve universal coverage.

XM’s system relies on two powerful geostationary satellites positioned directly above the equator, which are programmed to move in synchronization with the movement of the earth. To overcome interference from physical obstacles such buildings and mountains, the XM service service relies on a network of repeaters, which are antennas that receive the radio signal from the satellites and retransmit it to the subscriber’s receiver.

The Sirius system is based on a trio of satellites that travel in figure-8 shaped orbits. Because these orbiting satellites can rise much higher than geostationary satellites, interference from physical objects is minimized and a large network of repeaters is unnecessary. To keep the signal steady during the eight hours that the Sirius satellites’ orbit takes them to the other side of the earth, the company leases capacity on a geostationary satellite which feeds the signal to subscribers.

Satellite radio service also depends on digital compression technology, a technique that uses sophisticated algorithms to compress as much material as possible on the available bandwidth.

Satellite technology is revolutionizing the way people listen to radio. Find out more about satellite radio systems and what they can offer you athttp://specialty-products.info/satelliteradio/.

FM radio transmitter Systems

FM radio transmitter Systems

An FM transmitter is a portable device that plugs into the headphone jack or proprietary output port of a portable audio or video device, such as a portable media player, CD player, or satellite radio system. The sound is then broadcast through the transmitter, and plays through an FM broadcast band frequency. Purposes for an FM transmitter include playing music from a device through a car stereo, or any radio.

 

FM is also used at intermediate frequencies by most analog VCR systems, including VHS, to record the luminance (black and white) portion of the video signal. FM is the only feasible method of recording to and retrieving from magnetic tape without extreme distortion a signal with a very large range of frequency components — a video signal has components from a few hertz to several megahertz.

 

A radio transmitter design is a complex topic which can be broken down into a series of smaller topics. A radio communication system requires two tuned circuits each at the transmitter and receiver, all four tuned to the same frequency. The transmitter is an electronic device which, usually with the aid of an antenna, propagates an electromagnetic signal such as radio, television, or other telecommunications.

 

FM transmitters are usually battery driven, but some use the cigarette lighter socket in cars, or draw their power from the device itself. They are typically used with portable audio devices such as CD or MP3 players, but are also used to broadcast other outputs (such as that from a computer sound card) throughout a home or other building.

 

This product allows for very clear music, with good sound quality through your radio. Also, it scans and sets your presets automatically for the radio stations that will work best according to where you are at (you can choose to turn this option off if you’d like). I have nothing negative really to say about it, other than I had to read the instructions to understand how all of the little options worked.

Now, it is time for you to own fm radio transmitter if you are a car owner , it is very fashionable and convenient, Which one might be your choice? Do you want to have a look? Many surprises here, you can choose anyone.

Elements Of Music On Hold Systems

February 15th, 2010
No Comments »

Basically music on hold refers to the business practice of playing pre-recorded music to fill the silence that would be heard by telephone callers that have been placed on hold. Music on hold means making customers listen to music while they are kept on hold. On hold music plays an important role in the progress and profits of the company. Mainly music on hold is used in customer services. Songs played are supplied in stereo format to allow easy burning onto compact disc, but the music is mastered in mono as used on telephone answering systems.


The arrangements of music are made simple purposely and are tempting and don’t over shadow any automated voice over messages. Instruments used in music which is being played on phones are selected specifically so that they sound good to the listener. The quality of the music also depends upon the source of music that is from where it has been uploaded. Files which are pre broadband sound worse than the higher bit rate which is used these days. Some versions deliver CD quality music. Various providers provide specific sound formats which can be purchased online also. The various considerations while using the concept of music on hold are equipments and formats to be used, source of music, styles of music and benefits of using this technique. The source of music is radio, off the shelf commercial CDs, stock music on hold CDs and custom designed music on hold. The equipments used on most of music on hold systems are integrated into a businesses telephone system via an audio jack on the telephone equipment labeled music on hold. Compact disc is mostly the source of music which is digital files. Few older systems use cassette tapes which are played on tape players. Radio is another source of music.


This is very easy to play as it is just like playing a local radio station. But for this due permission has to be taken else it is considered illegal. The radio stations offer provide the desired music format but there is no control over the specific songs that are played, some of which may be unpleasant to the callers. Music on radios is not licensed for music on hold systems. Also radio broadcasters do not have right to provide any such rights as radio broadcasters themselves obtain a usage license from the music title owner for the right to broadcast said music for limited and personal use. Re broadcasting of a radio program over a phone system may likely cause licensing and copyright problems for the owner of the music on hold system. Also radio stations play commercials which can be unpleasant to the caller. Also it is possible that a competitor commercial may be played, which would be challenging.
