`
`Field of the Invention
`
`Background of the Invention
`
`[0002]
`
`The present invention relates to the field of audio file transfers
`
`and, more particularly, relates to the field of management and distribution of
`
`audio files over a computer network such as the Internet.
`
`Description of the Related Art
`
`[0003]
`
`The Internet is a worldwide array of interconnected computers and
`
`information servers that allow anyone with a computer and access to the
`
`Internet to get information about virtually any subject 24 hours a day. For the
`
`average consumer, an Internet Service Provider (ISP) provides access to the
`
`Internet.
`
`ISPs such as CompuServe, Prodigy, and America On-Line, currently
`
`link over ten million users to the Internet. Users typically connect to the ISP
`
`by using standard telephone 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.
`
`[0004]
`
`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
`
`6/331
`
`SAMSUNG EX. 1002
`
`6/331
`
`SAMSUNG EX. 1002
`
`

`

`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 traditional 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.
`
`[0005]
`
`Unfortunately, even with the ever-decreasing cost of personal
`
`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 computer, listening to a Web radio broadcast ties up the
`
`computer so that the user cannot 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 of the
`
`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.
`
`[0006]
`
`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
`
`[0007]
`
`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 convenience. The network-enabled audio device has a
`
`visual display 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 communications network. One embodiment includes a
`
`data storage device.
`
`[0008]
`
`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 location of other
`
`web sites containing the audio sources. The second software module is
`
`configured to subsequently connect through an Internet service provider to web
`
`sites to download audio files.
`
`[0009]
`
`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-
`
`8/331
`
`SAMSUNG EX. 1002
`
`8/331
`
`SAMSUNG EX. 1002
`
`

`

`broadcast 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.
`
`[0010]
`
`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 network—enabled audio device
`
`provides the hardware and software to perform those functions without the need
`
`for expensive equipment. Optionally, a Local Area Network can be configured in
`
`place of, or in addition to, the Internet connection 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.
`
`[0011]
`
`The network-enabled audio device provides a display device, such as 3
`
`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 AM/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 display in the network-enabled audio device are operably
`
`configured 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

`
`SAMSUNG EX. 1002
`
`9/331
`
`SAMSUNG EX. 1002
`
`

`

`listen to playlists and other audio sources without using the PC.
`
`[0012]
`
`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 connection such as Ethernet. The device includes a display
`
`device, speakers, a control panel, a computer processor, stored software, a
`
`modem, an AM/FM tuner, and a CD player. Optionally, 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.
`
`[0013]
`
`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 am, each
`
`device establishes a connection to an Internet Service Provider (ISP). The stored
`
`software module in each device connects 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.
`
`[0014]
`
`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,
`
`an AC 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 Phoneline Networking Alliance (HPNA) network connection so that the
`
`connection may be done through existing phone lines in a home. Optionally, the
`
`10/331
`
`SAMSUNG EX . 1002
`
`10/331
`
`SAMSUNG EX. 1002
`
`

`

`network connection can be an Ethernet connection. Multiple network-enabled
`
`audio devices can be connected to each other and ultimately to the PC through the
`
`network line.
`
`[0015]
`
`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.
`
`[0016]
`
`Another aspect of the present invention is a network-enabled
`
`component audio device system for listening to a variety 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 communications network.
`
`In one embodiment, a data
`
`storage device is provided.
`
`[0017]
`
`A first software module is configured to decode compressed 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.
`
`[0018]
`
`In one embodiment, the network-enabled audio device is a component
`
`hardware device for an audio system. The network—enabled audio device provides
`
`an audio output to the audio system. The audio system provides amplifiers and
`
`loudspeakers. 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
`
`11/331
`
`SAMSUNG EX. 1002
`
`11/331
`
`SAMSUNG EX. 1002
`
`

`

`line, an Ethernet line, aToken-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 display 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.
`
`[0019]
`
`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.
