`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`The present invention relates to the field of audio file trans-
`fers and, more particularly, relates to the field ofmanagement
`and distribution of audio files over a computer network such
`as the Internet.
`
`2. Description of the Related Art
`The Internet is a worldwide array of interconnected com-
`puters and information servers that allow anyone with a com-
`puter and access to the Internet to get information about
`virtually any subject 24 hours a day. For the average con-
`sumer, an Internet Service Provider (ISP) provides access to
`the Internet. ISPs such as CompuServe, Prodigy, andAmerica
`On-Line, currently link over ten million users to the Internet.
`Users typically connect to the ISP by using standard tele-
`phone lines and a telephone modem. Cable modems that
`allow a user to connect to the ISP over cable television lines,
`and satellite connections to the Internet, are also available.
`The Internet provides a wealth of information from stock
`reports to headline news. One of the newer services provided
`on the Internet is a streaming audio (e.g., RealAudio and
`MPEG audio) service. Streaming audio services are often
`provided in connection with the World Wide Web (Web) and
`thus are often called Web radio broadcasts. With streaming
`audio, a user with a Personal Computer (PC), a sound card,
`and the necessary software can listen to audio programs from
`anywhere in the world. For example, Radio Prague provides
`daily Internet broadcasts from the Czech Republic. Listeners
`in the U.S. can listen to these Web radio broadcasts either in
`
`real time, or stored for later replay. Thus, unlike more tradi-
`tional radio broadcasts where the listener must be within a
`
`reception area, Web radio broadcasts can be heard anywhere,
`so long as the listener has a connection to the Internet and the
`necessary computer hardware and software.
`Unfortunately, even with the ever-decreasing cost of per-
`sonal computers, the hardware and software needed to listen
`to a Web radio broadcast is beyond the financial means of
`many people. Even for those that can afford a personal com-
`puter, listening to a Web radio broadcast ties up the computer
`so that the user carmot use it for other purposes. Moreover, the
`use of a personal computer to receive streaming audio (e.g.,
`Web radio broadcasts) requires a certain amount of computer
`literacy on the part ofthe user. The user must be able to install
`the Web Radio software, configure the Web Radio software to
`communicate with the ISP, and find the various Web radio
`broadcasts provided on the Web.
`In addition to listening to Web radio broadcasts, users may
`wish to listen to audio files. With a group of PC’s in a home
`and in a network, users can download songs from one PC to
`

`
`another or upload songs from one PC to another. However,
`users cannot play a song on one PC by using the controls of
`another PC. In addition, the users must purchase multiple
`PC’s, which can be costly. Further, the user must be able to
`install the network connection and the appropriate software.
`Moreover, even if the user can afford to purchase multiple
`PC’s and install the proper connection, the user would have
`difficulty playing music in addition to performing other tasks
`on the PC. For example, the Web radio broadcast may be
`interrupted. Also, a skip over parts of a song may result if the
`user is using a word processing program at the same time as
`listening to music.
`
`SUMMARY OF THE INVENTION
`
`The present invention solves these and other problems by
`providing a network-enabled audio device for listening to a
`variety of audio sources with substantially equal conve-
`nience. The network-enabled audio device has a visual dis-
`
`play for providing audio source choices to a user. The visual
`display also provides functions for managing audio sources.
`User control buttons allow a user to choose an audio source to
`listen to. The menu buttons allow the user to choose functions
`
`for managing the audio sources. In one embodiment, there is
`also tuner circuitry for receiving radio frequency signals from
`radio broadcast stations. In one embodiment, a CD player
`allows the user to listen to CD’s. In one embodiment, the
`network-enabled audio device also has one or more audio
`
`amplifiers and one or more loudspeakers operably connected
`to said audio amplifiers. In one embodiment, a modem is used
`for transmitting and receiving digital data over a communi-
`cations network. One embodiment includes a data storage
`device.
`
`A first software module is stored on the data storage device,
`and the software module is configured to decode compressed
`audio files into a playable (e.g. uncompressed) format. A
`second software module is also stored on the data storage
`device. The second software module is configured to use the
`modem to connect to an Internet service provider to receive
`assignments of playlists from a third software module. The
`playlists include references to audio from a variety of audio
`sources. The assignments provide information about the loca-
`tion of other web sites containing the audio sources. The
`second software module is configured to subsequently con-
`nect through an Internet service provider to web sites to
`download audio files.
`
`A third software module is also stored on the data storage
`device. The third software module is configured to use the
`modem to connect to an Internet service provider to receive
`digitized audio broadcasts from the Internet service provider.
`The module is further configured to provide a select-broad-
`cast display to allow the user to selectably connect a program
`broadcast to the input of one or more audio amplifiers either
`from a local AM or FM radio station or from the world wide
`
`Web so that, to the user, reception of a broadcast from the
`World Wide Web is no more complicated than listening to a
`local FM or AM radio station.
`
`One aspect of the present invention is a network-enabled
`audio device that allows a user to store files, to play standard
`audio CD’s, to play MP3 encoded CDs, to record songs from
`CD’s, to receive digitized radio broadcasts over the World
`Wide Web (Web), and to receive assignments of playlists of
`songs from other network-enabled audio devices. The net-
`work-enabled audio device provides the hardware and soft-
`ware to perform those functions without the need for expen-
`sive equipment. Optionally, a Local Area Network can be
`configured in place of, or in addition to, the Internet connec-
`
`Page 53 of 71
`
`Page 53 of 71
`
`

`
`US 8,050,652 B2
`
`3
`tion to facilitate assignments of playlists and other features.
`Without an Internet connection or other network connection,
`the network-enabled audio device can play standard audio
`CD’s, can play MP3 encoded CD’s, and can record CD’s.
`The network-enabled audio device provides a display
`device, such as a Liquid Crystal Display (LCD) that allows
`the user to select playlists of music much like a jukebox. The
`user can compose playlists from disk files, CD’s, Internet
`streaming audio broadcasts, online music sites, and other
`audio sources. In one embodiment, the user can also compose
`playlists from links to Al\/I/FM broadcasts. The user can also
`select a desired Web broadcast from a list of available Web
`
`broadcasts. In addition, the user can play standard audio CD’ s
`and MP3 encoded CD’s and have access to local AM/FM
`
`stations. Further, the software, the user controls, and the dis-
`play in the network-enabled audio device are operably con-
`figured and connected such that the user can listen to playlists
`that include CD’s and other audio sources just as the user
`would choose a playlist in a jukebox. Thus, the network-
`enabled audio device provides people who are or are not
`comfortable with computers a way of taking music from
`various sources and putting it into one place for listening
`pleasure. In one embodiment, the Personal Computer (PC) is
`used to compose the playlists, but the user is able to listen to
`playlists and other audio sources without using the PC.
`In one embodiment, the network-enabled audio device is a
`low-cost tabletop box that connects to an AC power line and
`optionally to a phone line or to a local area network connec-
`tion such as Ethernet. The device includes a display device,
`speakers, a control panel, a computer processor, stored soft-
`ware, a modem, an Al\/I/FM tuner, and a CD player. Option-
`ally, the device can include multiple computer processors or
`support computer processors. The user accesses the server
`site via a PC and the Internet. From the server site, the user
`obtains a list of the devices in his or her Internet Personal
`
`Audio Network (IPAN) and what songs are on those devices.
`The IPAN includes an IPAN server, an IPAN client, and IPAN
`software stored on the network-enabled audio device. In one
`embodiment,
`the IPAN client
`includes a standard web
`browser, an IPAN plug-in to the standard web browser, and an
`IPAN active tray software module. In one embodiment, any
`standard web browser may be used, but the IPAN client
`includes the IPAN plug-in and the IPAN active tray software
`module.
`The IPAN client and the IPAN server store the name of the
`
`song and the associated Uniform Resource Locator (URL).
`The user can list multiple devices as being part of his or her
`IPAN. At a default time, such as for example 2 a.m., each
`device establishes a connection to an Internet Service Pro-
`
`vider (ISP). The stored software module in each device con-
`nects to the server site home page, via the ISP, and inquires
`whether any songs or playlists have been assigned to the
`device. The user can bypass the default time for accessing the
`server and access the server by manually pressing one of the
`buttons.
`In one embodiment, the network-enabled audio device has
`no disk for data storage space. Rather, a local area network
`(LAN) connection to a PC or other network-enabled audio
`device allows the use of disk space on another device. In one
`embodiment, the network-enabled audio device comprises
`speakers, anAC power line, and a network line. A home PC is
`connected to the network-enabled audio device through the
`network line. The network connection can be a Home Phone-
`
`line Networking Alliance (HPNA) network connection so
`that the connection may be done through existing phone lines
`in a home. Optionally, the network connection can be an
`

`
`connection. Multiple network-enabled audio
`Ethernet
`devices can be connected to each other and ultimately to the
`PC through the network line.
`In one embodiment, the network-enabled audio device
`does not have any storage space other than memory. This
`embodiment provides for a low-cost system that can play
`songs from playlists stored on the IPAN Manager or on the
`PC’s storage space without having to store the audio files
`locally.
`Another aspect of the present invention is a network-en-
`abled component audio device system for listening to a vari-
`ety of audio sources with substantially equal convenience. A
`visual display provides audio source choices to a user. The
`visual display also provides menu choices for managing
`audio sources to the user. The user control buttons allow the
`user to choose an audio source to listen to. The menu buttons
`
`allow the user to choose functions for managing the audio
`sources. The network-enabled component audio device has a
`CD player for listening to compact discs.A modem is used for
`transmitting and receiving digital data over a communica-
`tions network. In one embodiment, a data storage device is
`provided.
`A first software module is configured to decode com-
`pressed audio files. The first software module is stored on the
`data storage device. A second software module is configured
`to use the modem to connect to an Internet service provider to
`receive assignments of playlists from the second software
`module. The playlists include titles of audio from a variety of
`audio sources. The assignments provide information about
`the location of other web sites containing the audio sources.
`The software module is configured to connect through the ISP
`to the web sites to download the audio files.
`
`In one embodiment, the network-enabled audio device is a
`component hardware device for an audio system. The net-
`work-enabled audio device provides an audio output to the
`audio system. The audio system provides amplifiers and loud-
`speakers. The network-enabled audio device includes an
`enclosure that connects to an AC power line, a network line,
`and the audio system. The network line is a computer data
`connection, such as, for example, a telephone line, a cable
`line, an Ethernet line, a Token-Ring line, a twisted pair line, an
`infrared link, a radio frequency link, an IEEE 1394 FireWire
`line, etc. The network-enabled audio device includes a dis-
`play device, a control panel, at least one computer processor,
`a stored software module, and a modem. In one embodiment,
`the network-enabled audio device connects to the IPAN
`server site.
`
`Another aspect of the present invention is a method for
`assigning playlists of music from one electronic device to
`another. First, a network connection is used for transmitting
`and receiving digital data over a communication network to
`an Internet service provider. Next, the process provides a first
`software module to manage playlists of songs. The software
`module allows a user to compose playlists from a variety of
`audio sources. The software module allows a user to assign a
`playlist from a first device to a second device. Next, the
`process checks the second device’s data storage space for
`songs listed on the assigned playlist. Next,
`the process
`accesses a server site to obtain locations of the web sites the
`
`first device downloaded its audio files from. The process then
`provides a second software module to connect to various web
`sites to download remaining songs needed for the playlist.
`The second software module connects if songs needed to
`form the playlist are not stored on the second device’s data
`storage space. Finally, the process uploads files to the server
`

`from the first device and downloads files the second device if
`the second software module is unable to download a file from
`said web site.
