Description

INTERNET RADIO RECEIVER HAVING THE APPEARANCE OF A CONVENTIONAL RADIO RECEIVER

CROSS REFERENCE TO RELATED APPLICATIONS This application claims the benefit of United States Provisional Application No.

60/1 15.076. filed January 7. 1999. entitled Internet Radio System.

BACKGROUND OF THE INVENTION

Field Of The Invention

This invention relates to communication systems: and more particularly, to a radio

system using a non-radio frequency media for information transfers using an established

network, such as the Internet.

2 Description Of The Prior Art

Conventional radios receive radio frequencies from stations over limited

geographical regions. As the distance between signal transmitter and receiv er increases,

radio reception decreases. Broadcasts from the station degrade and are eventually lost.

Radio listeners have distinct programming preferences; many of them prefer

programs broadcast in foreign languages. Due to geographical constraints on signal

transmission and reception, the availability of such programming has been limited.

There remains a need in the art for a communication system that transmits radio

station content over vast geographical regions, permitting foreign station broadcasts to be

received in the United States, for example, without station degradation. Such a

communications system exists over the Internet, wherein the communications receiv ers are

Personal Computers (^"PC^'s^"). PC^"s. however, are complex and expensive devices. Many people do not own or have access to a PC; or if they do. they may not wish to use a PC for

radio listening. In addition, connections to the Internet via an Internet Service Provider are

generally available on a subscription basis, requiring a monthly fee. The acceptance of

entertainment services has. in general, been impeded by the requirement of a subscription

fee. Accordingly, there remains a need for broad access to radio entertainment sources via a

media such as the Internet. Especially needed for providing such access is a device that

would be characterized as a radio, not a PC.

SUMMARY OF THE INVENTION

The present invention provides a radio communication system for transmitting the

content of radio stations over large geographical regions without the limitations imposed by

radio frequencies as the delivery medium. Foreign station broadcasts are readily received in

countries on different continents without station degradation.

The term "radio station^" is used herein to describe Internet entertainment content

providers typical of the state of the art. It will be understood, however, that this term is

intended to represent the general category of entertainment content providers on the

Internet. This category includes, but is not limited to, Internet only "virtual^" radio stations,

web sites that deliver stored audio or video program material, and similar program

originators. Accordingly, as used hereinafter in the specification and claims, the term

"radio station^" means any entertainment content provider capable of delivering its content

over the Internet.

In one aspect of the invention, there is provided an Internet radio system for

receiving an Internet radio program, which may induc e formatted text, graphics, and video -

in addition to the radio station^'s audio. Generally stated, the Internet radio system

comprises connecting means for connecting the radio to an Internet service provider;

microprocessor means: memory means; amplifier means: digital signal processor means for

processing audio signals of the radio program: digital-to-analog converter means for

converting the processed audio signals for input to said amplifier: audio speaker means

comprising at least one audio speaker; tuning means for selecting an Internet address of

said radio program; control means for causing said microprocessor to set audio preferences,

such as volume and balance, of said amplifier: and display means for displaying said

formatted text, graphics, and video. The Internet Radio System is distinguished from a PC

in that it is designed to provide very specific and limited functionality, such as changing

stations and adjusting audio volume, which can be performed within the scope of a narrow

set of controls such as buttons, knobs, and a TN style infrared remote control. The limited

set of functions being provided, and the associated limited set of controls, enable an Internet

Radio System that is as easy to operate as a traditional radio. Current generation PC^'s

include a mouse and a keyboard to facilitate user interaction with a complex system: the

mouse and keyboard can be generally thought of as the control devices that distinguish a PC

from other of the wide variety of commonly available computer controlled consumer

appliances such as microwave ovens and cellular telephones. The Internet Radio System is

therefore further distinguished from a PC in that it does not include a mouse or a keyboard.

such systems commonly being referred to as standalone or non-PC devices or appliances.

Computer users interact with the Internet by using the computer^'s mouse and

keyboard to facilitate dialing phone numbers, login and password negotiation, the selection

of destination (URL or IP address), and the like. In the absence of a kevboard and mouse to facilitate these interactions, tre Internet Radio System is designed as part of an end-to-end

solution that includes the cooperation of one or more ISP^'s, Internet Hosting Services, and

radio stations. The managing entity of these cooperating organizations maintains a

centralized, toll-free telephone number that provides a referral service to Internet Radio

Systems of local phone numbers of cooperating ISP^'s. Using CallerlD or a user provided

zip code, the centralized referral service determines the location of the Internet Radio

System and selects a local phone number for access to an ISP. The referral service then

transmits this local phone number to the Internet Radio System. The Internet Radio System

makes subsequent dialup calls to this local number. Based on the preceding, if dialing is

required to access an ISP. the Internet Radio System dials into a predetermined ISP via a

preprogrammed local phone number. Once connected, the Internet Radio System transmits

a unique identifying and authorizing message to the ISP, which, upon recognizing the

Internet Radio System, routes the connection to a predetermined Internet Hosting Service

destination. The Internet Hosting Service, which may be the same entity as the ISP,

provides the Internet Radio System with access to radio station content. The entire process

of dialing, logging in. and destination selection is automatic for the Internet Radio System,

thus negating the need for a mouse and keyboard.

Therefore, in another aspect, the invention provides a method for receiving and

playing audio, as well as displaying formatted text, graphics, and video from an Internet

radio station on an Internet radio device, comprising the steps of: a) connecting said device

to a predetermined Internet Service Provider; b) providing a predetermined authorizing

identification number for said device to said Internet Service Provider; c) logging into said

Internet Service Provider; d) connecting to an Internet Hosting Service providing access to one or more radio stations, which Hosting Service may be said Internet Service Provider; e)

receiving a station list from said Internet Hosting Service or Service Provider; f) storing

said list in memory of said device; g) selecting a station from said station list; h) receiving

digitized audio from said station via said Internet Hosting Service or Service Provider; i)

converting said digitized audio to analog audio: j ) playing said analog audio; k) receiving

text messages provided by said radio station or Internet Hosting Service or Service

Provider; 1) storing said text messages in memory of said device; m) receiving text format

commands provided by said Internet Hosting Service or Service Provider; n) storing said

text format commands in memory of said device; o) formatting said text messages with said

text format commands p) displaying said formatted text messages; q) receiving graphics

commands provided by said radio station or Internet Hosting Service or Service Provider; r)

storing said graphics commands in memory of said device; s) processing said graphics

commands; and t) displaying said processed graphics.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention will be more fully understood and further advantages will become

apparent when reference is had to the following detailed description and the accompanying

drawings, in which:

Fig. 1 is a block diagram showing a preferred embodiment of an Internet radio

system in accordance with the present invention; and

Fig. 2 is a block diagram showing an alternate embodiment of the Internet radio

system wherein the radio is equipped with an FM radio tuner for receiving conventional FM

radio transmissions over the airwa\ s. DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to Figs. 1 and 2 of the drawings, there is shown a radio communication

system for receiving Internet radio programs, text, graphics, and video broadcast via the

Internet. The radio communication system of Fig. 2 has means for receiving regular FM

radio transmissions and making credit card transactions with enhanced security for the

vendor.

In the embodiment shown, the radio is a stand-alone device equipped to receive

radio programs, formatted text, graphics, and video via the Internet without the use of a

personal computer.

Generally stated, the radio is microprocessor controlled and further comprises an

operating system, browser software, and memory. The operating system can be unique and

dedicated to the radio, or can comprise a commercially available system such as

WindowsCE. Preferably, the operating system and browser are stored as firmware in non-

volatile memory.

A block diagram for the preferred embodiment of the radio communication system is

shown in Figure 1. The microprocessor controlled radio 12 has a means for connecting to

an Internet Service Provider (ISP) 14. such as a telephone modem or a cable modem. When

turned on. the radio operating system initiates an automatic connect, logs-on with the ISP 10

and connects with a web page having a list of available Internet radio stations by format

(i.e.. country, jazz, rock), type (i.e., foreign, commercial, public, college), or language.

Using a control means 20. the user selects the radio program to be listened to from the list

which is presented on display means 22, and stored in memory means 18. The control means also provides means for causing the microprocessor 16 to set the volume, balance,

etc. of the device^'s amplifier 26. The control means 20 is implemented as knobs and

buttons as with a conventional radio, or as virtual knobs and buttons activated by a touch

sensitive display means or a TV-style infrared remote control. A digital signal processor

(DSP) and a digital-to-analog converter provide a means 24 for converting the

microprocessor output of the Internet radio program for the amplifier 26 and speakers 28.

In Figure 2 there is shown a block diagram of an alternate embodiment of an Internet

radio system. The preferred embodiment is further provided with a FM radio tuner 30 for

receiving regular FM radio transmissions over the airways. A selector means 32 is provided

for switching between these normal broadcasts and Internet programs. The selection is

made by the user by way of the control means 20. which causes the microprocessor 16 to

direct the switching means to become operative.

As a further alternative, a magnetic strip card reader 34 is provided for reading the

user^'s credit card and then transmitting the card information to a vendor. Upon connecting

with the vendor on the Internet, the credit card information is transmitted to the vendor,

confirmation of the completed transaction is then transmitted to the user^'s Internet radio

system 12 and displayed on its display means 22. The vendor can use Caller ID to verify

the user^'s identity.

The connection to the Internet is preferably provided at no cost, as disclosed in co-

pending U.S. Patent application of Emerson, et al.. filed January 7. 1999 for "Method for

Transmitting Advertisements Over the Internet^", the entire disclosure of which is

incorporated herein by reference thereto. Having thus described the invention in rather full detail, it will be understood that

such detail need not be strictly adhered to. but that various changes and modifications may

suggest themselves to one skilled in the art, all falling within the scope of the invention, as

defined by the subjoined claims.
