   FIELD 
   Embodiments of the present invention relate to promotional digital audio players. 
   BACKGROUND 
   Programmable devices make great marketing tools. As is familiar today, applications can be programmed to cease to function upon expiration of a trial period or to disable certain functionalities. Often when a consumer purchases a computer, for example, the computer comes bundled with trial versions of software applications, such as anti-virus software or Internet software, which expire unless the full software application is purchased or subscribed to. 
   Of course, free merchandise is another great marketing tool. Companies often give away goods such as mouse pads, coffee mugs and key chains—goods that tend often to be within eyesight of a consumer, which bear the companies&#39; logo, tagline, and contact information. 
   Cell-phones, personal data assistants (“PDAs”), and MP3 players are being distributed very broadly today and offer good marketing possibilities. Up until recently, though, the cost of goods for these devices was too high for companies to consider free distribution. Recently, however, it has become possible to manufacture MP3 players and similar devices at very low cost. 
   Thus a powerful opportunity has arisen for designing promotional MP3 players and similar devices, which leverage both the marketing advantages of programmable operation and the marketing advantages of free distribution.

   DETAILED DESCRIPTION 
   Digital music players are proliferating as standalone consumer electronic devices such as MP3 players, as bundled components within portable devices such as personal data assistants (PDAs) and cell-phones, and as home network appliances. Listeners typically build up their own personal libraries of digital songs, which are stored on memory units such as hard disk drives and removable memory cards. Digital songs are typically acquired through the Internet via subscription services and peer-to-peer exchanges, or by converting songs from a compact disc (CD) and importing them into an MP3 library. 
   Digital songs typically include audio data and auxiliary data, referred to as meta-data, used to index the songs within the listener&#39;s library. For example, MP3 files include embedded meta-data that is accessed through an ID3Tag. WMA files include embedded meta-data in the files and also within the filenames themselves. By indexing the songs, a listener can search his library and access individual songs therein. Audio players generally provide a user interface through which users view meta-data. 
   Building up a digital music library requires a lot of time and work. Typically, a listener first searches the Internet for one or more songs of interest, then identifies locations of the songs, and then downloads them into a database associated with a media player. Songs are typically stored as digital files, formatted in compliance with a standard format, such as MP3 or WMA. Once the songs are downloaded, the listener generally uses player software, such as Windows Media player or Winamp, to play the songs on a computer, or alternatively he copies the songs onto a hardware device, such as an iPod™ or other MP3 player that plays the songs. 
   A shortcoming in the world of digital music is the great effort required to build custom music libraries at home. Often individuals spend nights on end downloading their favorite songs and building their own personal music libraries. An alternative is to purchase libraries that have been prepared by others, but often someone else&#39;s library does not match a listener&#39;s taste and the listener prefers to collect his own favorite songs. 
   A popular source for a listener to hear his favorite songs is on music stations. Cable, satellite broadcast and the Internet provide music channels for almost every genre of music—classical music, rock and roll, jazz, music of the 50&#39;s, etc. A listener can enjoy music according to his taste by subscribing to such broadcast services. 
   Applicant&#39;s co-pending U.S. patent application Ser. No. 10/336,443, entitled AUTOMATIC DIGITAL MUSIC LIBRARY BUILDER, now U.S. Pat. No. 7,191,193, filed on Jan. 2, 2003, describes a device that enables a listener to automatically copy and import songs that are broadcast from a music station into his digital music library, along with the songs&#39; meta-data required for indexing his library. A listener, with practically no effort, can automatically build up a large digital music library with tens of thousands of his choice of songs, all properly indexed for search and retrieval. 
   Applicant&#39;s automatic digital music library builder is preferably embodied in a programmable device, referred to herein as a “Nest,” that can interface with computers, with MP3 players and other digital music players, and with other electronic devices that include MP3 players or other digital music players therewithin, including inter alia cell phones, PDAs, home network appliances, and Internet appliances. For a first embodiment, the Nest is coupled to a satellite/cable receiver; for a second embodiment, the Nest is coupled to a television; for a third embodiment, the Nest is coupled to various external components via a USB and a Firewire connection. 
   The memory storing the digital music library can be either a large hard disk situated within the Nest itself, or one or more smaller removable memory units such as compact disks and memory cards, or a combination of hard disk and removable memory. The advantage of a large hard disk is that the listener&#39;s music library is consolidated into a single library that can be searched and accessed in its entirety. The advantage of removable memory units, such as compact disks, is that the listener can insert the disks into portable players such as MP3 players. Assuming that 40 songs on average require 128 MB of data and include one and a half hour&#39;s worth of listening, a large 80 GB hard disk can hold a library of approximately 25,600 songs; and a 640 MB compact disk can hold approximately 200 songs, or about 7½ hours worth of listening. 
   Reference is now made to  FIG. 1 , which is a front view of a Nest  100 . Nest  100  is shown with its front panel open. On the left side of the front panel are female left and right analog audio-in connectors  110  and  120 , and a female analog video-in connector  130 , used for connecting auxiliary audio and video devices, such as a CD player, in order to add content into the Nest. On the right side of the front panel are female USB sockets  140  and  150 , used for connecting foreign MP3 players to the Nest; a female Ethernet connector  160 , for connecting the Nest to a computer network; and a mini-jack socket  170 , used to provide analog stereo audio-out for headphones. 
   A Nest includes one or more exchange ports  180 , also referred to herein as “cradles,” through which one or more hand-held digital music players, referred to herein as “Eggs,” can be connected to the Nest, for loading songs from a digital music library stored on the Nest thereto. Such exchange ports may be circular or oval ports into which Eggs in the shape of film canisters are inserted. Thus it may be appreciated that Eggs may be “charged up” with songs while they are plugged into the cradles of the Nest. 
     FIG. 2 , is a side view of an Egg  200 , in accordance with an embodiment of the present invention. Egg  200  is shown with a panel  210  that displays meta-data for a song currently being played. As can be seen in  FIG. 2 , the meta-data includes a title (“Blowing in the Wind”), an author (“Bob Dylan”) and an album (“Bob Dylan&#39;s Greatest Hits”). 
     FIG. 3  is a bottom view of Egg  200  of  FIG. 2  in accordance with an embodiment of the present invention. The bottom of Egg  200  includes a female audio/video connector  210 , which for one embodiment is used for transferring analog audio and analog video between the Egg and a Nest; and a female USB connector  220 , which for one embodiment is used for transferring digital data between the Egg and a Nest, between the Egg and a “filling station” kiosk, and between the Egg and another Egg. Corresponding to connectors  210  and  220 , the cradles of the Nest contain male analog audio/video connectors and male USB connectors (not shown in  FIG. 1 ). 
   Egg  200  may optionally include SSD memory, HD memory, or a combination of SSD and HD memory. Alternatively, Egg  200  may have no writeable memory. 
   A typical usage scenario for a Nest and Egg is as follows. A listener sets his cable or satellite receiver box to a specific music channel, such as The Music Choice®, and activates the Nest to capture songs from the music channel. The Nest automatically creates a digital music library and imports the broadcast songs therein. Thereafter, the listener plugs an Egg into a cradle of the Nest, and downloads selected songs from the music library onto the Egg. If the Nest is connected to the listener&#39;s speaker system, then the listener may also pipe music from the Nest into speakers in various rooms. If the Nest is connected to a home network, the listener may stream audio to a computer that is authorized to work with the Nest. 
   In addition to the Nest being able to download songs to the Egg when the Egg is connected to the Nest, for one embodiment the Nest is also able to remove songs stored in the Egg. Thus, if the Egg storage is full, the Nest can remove songs from the Egg, in order for the Egg to download a new set of songs. 
   Eggs of embodiments of the present invention may receive digital music from other sources, in addition to the Nest. Thus the Eggs may be compatible with kiosks, such as music kiosks located in music distribution stores, used for listening to songs prior to purchase and for subsequent purchase. For one embodiment, when an Egg is connected to a Nest, the digital music that was received from other devices and stored within the Egg can be archived on the Nest. 
   An Egg may receive control commands through its USB connector. Specifically,
         when connected to a Nest, the Nest may issue control commands to the Egg, such as a command to advance to the next song; and   when connected to a docking station, such as a docking station for the Egg in a room of a house, the docking station may receive infrared commands issued by a user, and translate them into control commands to the Egg over the USB connector.       

     FIG. 4  is an illustration of a graphical user interface (GUI) for copying songs from the Nest of  FIG. 1  into the Egg of  FIG. 2 , in accordance with an embodiment of the present invention. The GUI shown in  FIG. 4  is displayed on a television or other display device connected to the Nest, and interactively controlled through use of a remote control device, such as an infrared control unit. As such, the GUI of  FIG. 4  is intended for navigation with simple directional buttons and a select button, such as are typically included in infrared control units. 
   The GUI shown in  FIG. 4  is used to organize a digital music library and create playlists; i.e., sequences of songs for playing from the Nest, or for copying songs to an Egg for playback from the Egg. 
   Embodiments of the present invention concern promotional Eggs, which for one embodiment are distributed for free in order to promote sales of Nests. Reference is now made to  FIG. 5 , which illustrates a plurality of promotional Eggs in accordance with an embodiment of the present invention. 
   An objective of the promotional Eggs is to provide limited but useful functionality to a consumer, and sway the consumer to purchase a Nest and upgrade the promotional Egg to a regular Egg. 
   Useful features and functionality of a promotional egg include, inter alia, one or more of the following:
         branded design on the outside casing;   SD slot or other memory card interface;   clock display;   plays a commercial related to the branded design, or related to the distributor of the promotional Egg;   buzzer, either speaker or piezo-based;   buzzes at pre-set times of day, optionally based on geographic location, such as Jewish or Moslem prayer times that depend on sunrise and sunset; and   plays audio, such as prayers, following the buzzer.       

   The Egg may include SSD or HD memory. Alternatively, the Egg may have no writeable memory. 
   For one embodiment, the commercial played by a promotional Egg is non-erasable and is played, during a promotional period, whenever a song is played, or whenever the promotional Egg is turned on. The commercial stops playing altogether after the promotional period lapses, the promotional period lapsing upon occurrence of a pre-determined event, including, inter alia, one or both of the following:
         when an offer is redeemed, such as registering the Egg with a Nest; or   after a pre-determined time has elapsed.       

   A promotional Egg may function as an alarm clock for a prayer schedule for members of a faith that requires prayer at regular times during the day, such as the Jewish or Moslem faith. Such prayer schedules often depend on times of sunrise and sunset at a specific geographic locale. 
   In reading the above description, persons skilled in the art will realize that there are many apparent variations that can be applied to the methods and systems described. Thus, after a pre-determined time has elapsed, the promotional Egg may be programmed to continue to automatically play the commercial whenever the Egg is turned on, but to stop the automatic playing of the commercial that had been occurring whenever a song was played. 
   In this way, the automatic playing of the commercial may be phased out over stages. Specifically, at stage one, when the promotional Egg is first distributed to a consumer, the commercial is automatically played whenever the Egg is turned on and whenever the consumer plays a song. At stage two, after a pre-determined time has elapsed, the commercial continues to automatically play whenever the Egg is turned on, but no longer automatically plays when the consumer plays a song. At stage three, after the consumer registers the Egg with a Nest, the commercial stops automatically playing altogether. 
   Table I describes the phasing-out of the automatic playing of the commercial by the promotional Egg, in accordance with an embodiment of the present invention.

     FIG. 6  is a simplified block diagram of a promotional digital audio player  200 , in accordance with an embodiment of the present invention. Promotional digital audio player  200  includes a memory  230  storing digital songs  240  and a digital commercial  250 . A digital-to-analog convertor  260  converts digital audio to analog audio, for playing by an analog audio player  270 . A processor  280  controls the playing of songs  240  and the automatic playing of commercial  250 , so that promotional digital audio player  200  automatically plays commercial  250 , and phases out the automatic playing of commercial  250 , as indicated in Table I hereinabove. 
     FIG. 7  is a flowchart of a method for automatically playing a commercial on a promotional digital audio player, in accordance with an embodiment of the present invention. At operation  310  a promotional digital audio player, such as digital audio player  200  ( FIG. 6 ), experiences a trigger event such as, for example, being turned on or receiving a request to play a song. 
   At operation  320 , a determination is made whether or not the promotional digital audio player has been registered. If so, at operation  330 , a processor of the digital audio player, such as processor  280  ( FIG. 6 ) does not cause a commercial, such as commercial  250  ( FIG. 6 ), to be automatically played. 
   Otherwise, if operation  320  determines that the promotional digital audio player has not been registered, then the method advances to operation  340 , where a determination is made whether or not a designated time period has elapsed. If not, at operation  350 , the processor causes the commercial to be played. 
   Otherwise, if operation  340  determines that the designated time period has elapsed, then the method advances to operation  360 , where a determination is made whether the trigger event was a request to play a song. If the trigger event was not a request to play a song, at operation  350 , the processor causes the commercial to be played. Otherwise, if the trigger event was a request to play a song, at operation  330 , the processor does not cause the commercial to be played. 
   In the foregoing specification, the invention has been described with reference to specific exemplary embodiments thereof. It will, however, be evident that various modifications and changes may be made to the specific exemplary embodiments without departing from the broader spirit and scope of the invention as set forth in the appended claims. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
