iPod is a new trends in the digital music player world. iPod is a brand of portable media players designed and marketed by Apple Inc. and launched on October 23, 2001. The product line-up includes the hard drive-based iPod Classic, the touchscreen iPod Touch, the video-capable iPod Nano, and the compact iPod Shuffle. iPod Classic models store media on an internal hard drive, while all other models use flash memory to enable their smaller size. As with many other digital music players, iPods can also serve as external data storage devices. Storage capacity varies by model.

Apple’s iTunes software can be used to transfer music to the devices from computers using certain versions of Apple Macintosh and Microsoft Windows operating systems. For users who choose not to use Apple’s software or whose computers cannot run iTunes software, several open source alternatives to iTunes are also available. iTunes and its alternatives may also transfer photos, videos, games, contact information, e-mail settings, Web bookmarks, and calendars to iPod models supporting those features. As of Sep 2009, more than 200,000,000 iPods had been sold worldwide, making it the best-selling digital audio player series in history.

The iPod line came from Apple’s “digital hub” category, when the company began creating software for the growing market of personal digital devices. Than, Apple decided to develop its own digital music player. The product was developed in less than one year and unveiled on 23 October 2001. Jobs announced it as a Mac-compatible product with a 5 GB hard drive that put “1,000 songs in your pocket.”.

The iPod line can play several audio file formats including MPEG-4, QuickTime Video Formats, MP3, AAC/M4A, Protected AAC, AIFF, WAV, Audible audiobook, and Apple Lossless. The iPod Photo introduced the ability to display JPEG, BMP, GIF, TIFF, and PNG image file formats. Originally, iPod software only worked with Mac OS; iPod software for Microsoft Windows was launched with the second generation model. Unlike most other media players, Apple does not support Microsoft’s WMA audio format—but a converter for WMA files without Digital Rights Management (DRM) is provided with the Windows version of iTunes. MIDI files also cannot be played, but can be converted to audio files using the “Advanced” menu in iTunes.

iPods with color displays use anti-aliased graphics and text, with sliding animations. All iPods (except the iPod Shuffle and iPod Touch) have five buttons and the later generations have the buttons integrated into the click wheel—an innovation that gives an uncluttered, minimalist interface. The buttons perform basic functions such as menu, play, pause, next track, and previous track. Other operations, such as scrolling through menu items and controlling the volume, are performed by using the click wheel in a rotational manner. Instead it uses a 3.5″ touch screen in addition to a home button, sleep/wake button and (on the second generation iPod touch) volume-up and -down buttons. The user interface for the iPod touch is virtually identical to that of the iPhone. Both devices use the iPhone OS.

iPod - Music in your pocket

Games in iPod

Video games are playable on various versions of iPods. The original iPod had the game Brick included as an easter egg hidden feature; later firmware versions added it as a menu option. Later revisions of the iPod added three more games in addition to Brick: Parachute, Solitaire, and Music Quiz. The games are in the form of .ipg files, which are actually .zip archives in disguise. When unzipped, they reveal executable files along with common audio and image files, leading to the possibility of third party games.

Laptop means Mobile Pc

File storage and transfer in iPod

All iPods except for the iPod Touch can function in “disk mode” as a mass storage devices to store data file. Generally, if a new iPod (excluding the iPod Shuffle) is initially plugged into a computer running Windows, it will be formatted with FAT32, and if initially plugged into a Mac running Mac OS X it will be formatted with HFS+.

Unlike many other MP3 players, simply copying audio or video files to the drive with a typical file management application will not allow an iPod to properly access them. The user must use software that has been specifically designed to transfer media files to iPods, so that the files are playable and viewable. Usually iTunes is used to transfer media to an iPod, though several alternative third-party applications are available on a number of different platforms.

A Brief History of Ipod

Roberto Sedycias asked:

iPod is a digital mp3 / mp4 player developed and marketed by Apple Inc., an American consumer electronics multinational corporation. During their research, Apple found that in comparison to available camcorders, digital cameras, and organizers; digital music players recorded poor sales, primarily due to their awful user interfaces. Apple wanted to do something about it and so Jon Rubinstein, Apple’s hardware engineering chief brought together a team comprising of Tony Fadell (who dreamed of a hard disk based music player), Michael Dhuey (hardware engineer), Jonathan Ive (design engineer), and Stan Ng (marketing manager). In less than a year, they designed a hard disk based music player, that had a 5 GB hard drive and capable of storing 1000 songs.

Apple’s iTunes software is utilized to operate the iPod (m3 / mp4 player). The software is compatible with all Mac systems. The operating system is stored on its hard disk. A boot loader program is contained in a NOR flash ROM chip (either 1 MB or 512 KB) which instructs the device to load the operating system from the hard disk. The iPod has a 32 MB of RAM, a portion of which is used to hold the operating system from firmware, and the rest is used to cache songs from the hard disk. Apple also invented a technology whereby the hard disk of iPod could spin up once and about 30 MB of upcoming songs could be cached into the RAM. This did not require the hard disk to spin up for every song and thereby saved battery power. Apple also introduced a Windows version of iPod, at a later stage.

The audio files that iPod (mp3 / mp4 player) supports are MP3, AAC/M4A, Protected AAC, AIFF, WAV, Audible audiobook, and Apple Lossless audio file formats. MIDI and WMA files can be played only after a convertor accomplishes conversion, for non-Digital Rights Management (DRM). Ogg Vorbis, FLAC, and other open-source audio formats are not supported at all.

Apple wanted an extremely user friendly interface and thus adopted the minimalist interface, which features only five essential buttons, namely, Menu (to access functions and to toggle the backlight); Center (for menu item selection); Play/ Pause (this also works as an off switch when held for few seconds); Skip Forward/ Fast Forward; and Skip Backwards/ Fast Reverse. An additional Hold button is provided for accidental button pressing prevention, and it can reset the iPod if it has frozen or crashed. Functions such as volume control, scrolling are handled by the usage of the rotational click wheel. Later models have some minor changes in the functions of the buttons but overall the number of buttons has remained at five.

To market this path-breaking mp3 / mp4 player, they needed a suitable futuristic name and so they hired a freelance copywriter, Vinnie Chieco, and other writers to give a name. Inspired by the movie 2001: A Space Odyssey and the dialogue “Open the pod bay door, Hal!” with reference to the context of the Discovery One spaceship and its white EVA Pods, Vinnie Chieco proposed the name of the product as iPod. The management of Apple accepted the proposed name and on 23 October 2001, the iPod was officially launched. The rest they say is history.

To enable customers to access songs of their choice, Apple opened up an online media store The iTunes Store on 29 April 2003, where individual songs could be downloaded at prices less than a U.S. dollar per song. The purchased songs can be played only on iPods. Subsequent versions of this iPod (mp3 / mp4 player) also featured video capabilities, and thus iTunes Store started selling short videos from 12 October 2005. From 12 September 2006, full-length movies were also available at the iTunes Store.

iPods have come a long way from their inception, and now the latest fifth generation iPods possess multimedia capabilities and are available in both Mac OS and Windows OS versions. Usually, if a new iPod is plugged into a Mac OS computer, then the hard disk of this mp3 / mp4 player is formatted as per the HFS+ file format, and if it plugged into a Windows OS computer, it is formatted as per the FAT32 file format. From being a digital music player, the iPod has now transformed into a digital media player.

Ipod - a Music Device of 21st Century

Roberto Sedycias asked:

In 2001, Apple Inc. launched portable media players of 21st century with a brand of iPod. The new range of iPod presents iPod classic which is hard drive based, iPod touch with a touch screen, iPod nano with video display and screenless iPod shuffle. Apart from them, the classic range of iPod includes iPod mini and iPod photo.

These digital music players can be used as external data storage devices but their capacities vary for each model. Music is transferred to the device with the help of iTunes software by Apple Inc. One can store music collection, and also play, tingle or split music from a CD with this software. In addition to that, photos, games, videos and calendars can also be transferred to the iPods that support such features. Apple`s iPods are easy to use.

iPod has created a history by selling 110 million units worldwide since September 2007. Apple`s CEO, Steve Jobs, decided to develop portable music device which is easy to use. He collected his team of hardware and software engineers and launched the product on October 23, 2001. This digital device used to have 5GB hard drive with a capacity to store at least 1000 songs. Apple took Portal Player`s and Pixo`s support to develop this product. Later Apple continued to develop refined versions of iPod.

iPods have the ability to display many audio file formats like MP3, Protected AAC, Audible audiobook, etc. whereas, file formats like JPEG, BMP, GIF, TIFF and PNG can be viewed with iPod photo. Similarly, upgraded versions of iPods can play the most advanced file formats. Though Apple doesn`t support Microsoft WMA format, but a converter for Window`s version of iTunes is provided for the same. When an iPod is associated with a computer, music libraries or playlists are synchronized manually or automatically with iTunes. 5G iPods come with click wheel to control the volume and 5 buttons which are used to play, stop, and go to next track, etc.

In order to provide songs for iPods, Apple launched an iTunes Store which can be accessed through iTunes. Rate per song varies from country to country. Buyer can purchase as many songs as he wants and enjoy the protected content. This Store became extremely successful immediately after its launch and then Apple made videos also available for sale in 2006. The purchased songs were downloaded with added encryption of AAC format as FairPlay DRM system. Later, DRM was made free in order to cease the manufacturing of pirated CDs.

In 2007, Apple reduced its rates for iTunes Plus songs and also of DRM coded tracks. Since iPod doesn`t play songs from its rival DRM technologies, it has bounded it`s user to iTunes Store only. With this Apple made limited profit, but later it enables to play music from online stores like eMusic or Amie Street. In 2007, Apple launched iTunes WiFi Music Store that enables a user to download songs from his iPhone or iPod. The downloaded media from iTunes Stores is transferred from iPods to computer with the help of software called iTunes 7 or above.

The sound quality on iPod can be enhanced with the equalizer, but one should keep in mind that high volume can cause bass distortion. The use of hardware in iPods like microcontroller, batteries, Audio chips etc. exclusively depend on the version of iPods. Upgraded iPods are available with more advanced technology. These days lots of accessories are marketed for iPods not only by Apple but also by other parties too. These accessories may enable a user to have FM radio tuners, wired remote controls etc.

iPods have marked their importance in the field of Education also, as it enables the user to download information, lesson plans etc. Apple is continuously working to bring upgrade versions of iPods.
