Microsoft worked with Japanese corporation Toshiba to produce the first generation Zune device, the Zune 1089. This is a portable media player with a HDD, or hard disk drive, which was launched in 2006. It can play music and video files, and features an FM radio. You can also use it to store and view photos. Charging the device takes about two hours.
The display, which forms the major part of the front face of the unit, is a 3-inch, low temperature, polysilicon TFT LCD. Polysilicon is also known as polycrystalline silicon, consisting of tiny crystals of silicon. TFT LCD is thin film transistor liquid crystal display. This kind of display is also used on some cell phones, computer monitors, handheld video game systems, PDAs, or personal digital assistants, projectors, satellite navigation devices and television sets.
HID refers to human interface device. In the case of the Zune 1089, there are mechanical switches in respect of all the unit's control surfaces. The I/O interface is the input/output system. The Zune 1089's I/O interface is two sockets, one for headphones and also a USB 2.0 socket.
The wireless local area network has a theoretical maximum speed of 54 Mbps, or megabits per second for IEEE 802.11g, a standard governing methods of wireless networking transmission. For IEEE 802.11b, the theoretical maximum speed is 11 Mbps. For either standard, there is a frequency channel selection of 2.4 GHz, or gigahertz. The wireless LAN module is WYSBAKSX2-A. The maximum antenna gain, indicating how efficiently the antenna changes input power into radio waves, is -0.3 dBi, or dB (isotropic), a theoretical indication of performance. The modulation type is DSSS for revision B, or direct-sequence spread spectrum. For revision G, the modulation type is OFDM, or orthogonal frequency-division multiplexing.
The mass storage capacity of the Zune 1089 is provided via a 1.8 inch HDD with a 30 GB, or gigabyte, capacity. The unit is powered by a Li-ion, or lithium-ion, battery. A key feature of the unit is the FM Tuner with RBDS. RBDS is the Radio Broadcast Data System. This is the U.S. version of the communications protocol RDS, the Radio Data System. There are slight differences between the two protocols.
As of April 2011, the latest Zune media players are the Zune HD 16, 32 and 64. Zune supports .wma, .mp4, .m4a, .m4b and .mp3 for audio; .wmv and .m4v for video; and .jpg for photos.
