iPod is a brand of portable media that is designed and marketed by Apple and launched on 23 October 2001. Since October 2004 iPod sales have dominated the market for digital music players in the United States.
Devices iPod range are primarily music players digital, designed around a central click wheel but the iPod shuffle has buttons only.
The full-sized model stores media on an internal hard drive, while the iPod nano and iPod smallest flash memory use shuffle. Like many digital audio players, iPods can also serve as external devices for data storage.
Besides playing music, iPods with display screens can display calendars, information contact, and text files, and play a limited series of video games. The models presented in 2004 include the ability to display photos and the fifth generation iPod, introduced in 2005, also can play video files. In January 2007, Apple announced the iPhone, which combines features of an iPod with video capability with integrated mobile phone and mobile Internet capabilities.
Apples ITunes software is used for transferring music (as well as photos, videos, games, contacts and calendars, for models that support those functions). As a free jukebox application, iTunes stores a comprehensive library of music the users computer and can play, burn and rip music from a CD. You can also sync photos and video.
History and Design:
The iPod was Apple's digital hub strategy, as the company began creating software for the growing market of digital devices purchased by consumers. If While digital cameras, camcorders and organizers had well-established major markets, the company found digital music players lacking user interface design and decided to develop its own.
The name was proposed by Vinnie Chieco, a freelance writer who (with others) was called by Apple to find out how to introduce the new player to the public. As soon as Chieco saw a prototype for the player thought the movie 2001: A Space Odyssey and the phrase: "Open the bay door of the pod, Hal!" Which refers to the white EVA Pods of the Discovery spaceship One At that moment the "iPod" was a name that Apple registered for Internet kiosks, but never put to use.
Head of Apple's hardware engineering Jon Rubinstein assembled a team of design engineers, including Tony Fadell, Stan Ng and Jonathan Ive. In addition, Sparkfactor Design has designed some of the teams iPod 2002-2004. They developed the product in less than a year and which was presented on 23 October 2001. CEO Steve Jobs announced that as a Mac-compatible product with 5 GB hard drive to "put 1000 songs in your pocket."
Strangely, Apple developed the iPod software entirely at home. Instead, Apple began with PortalPlayer's reference platform is based on 2 ARM cores. The platform uses software running on a rudimentary commercial microkernel embedded operating system. PortalPlayer had been working on an IBM branded MP3 player with Bluetooth headphones. Apple contracted another company, Pixo, to help design and implement the user interface, under the direct supervision of Steve Jobs.
Once established, Apple software continues to improve appearance. Starting with the iPod mini, the Chicago font (once used in the early Macintosh computers) was replaced with Espy Sans, which was originally used in eWorld and Copland. Later iPods again to Podium Sans change fonts, a font similar to Apple's corporate font Myriad. The iPods with screens color then adopted some Mac OS X themes like Aqua progress bars, and brushed metal in the lock interface.
User Interface:
Apple focused its development on the unique user interface of the iPod and its ease of use, rather than on technical capability. The iPod is currently the best selling van in the world digital audio players and its widespread adoption throughout the world makes it one of the most popular consumer brands. Some of Apple's design choices and actions owners, however, led to criticism and legal battles.
The iPods with color screens, use of high quality anti-aliased graphics and text, animations slip. These iPods have five buttons and the new generations have the buttons integrated into the click wheel, an innovation that offers an uncluttered, minimalist interface.
The buttons are:
Menu to go back through the menus and change the backlight on older when held iPods
Center to select a menu item
Play / Pause, which doubles as a switch when held
Fast Forward (When held) / Skip Forward
Fast Reverse (when held) / Skip Backward
Operations such as scrolling through menu items and volume control done by the click wheel on a rotating basis. These iPods also have a reserve switch on the top, which prevents accidentally pressed a button.
The new iPods automatically pause playback when headphones are disconnected from the headphone jack, but playback does not not resume when the headphones are re-inserted.
However, the new iPods (except iPod shuffle), when the headphones are re-inserted into the headphone jack when the iPod is asleep, iPod automatically wakes the screen from the last tour before going to sleep. An iPod that has crashed or frozen can be restored by turning off 'Hold' on further out, then holding Menu and Center (Menu and play in the 3G iPod) for 6 seconds.
The iPod shuffle does not use a click wheel and instead has five buttons positioned differently from the bigger models. This has a Play / Pause button in the center, surrounded by four buttons: Volume up / down and jump forward / backward. The button layout is shared by the Apple Remote (which ships with all Apple computers with Front Row and Universal Dock).
