Real Player Guide
RealPlayer is a media player known for its ability to play a wide range of video formats and with integrated support for a lot of video codecs, including MP3, MPEG-4, QuickTime, and Windows Media formats as well as multiple versions of proprietary RealAudio and RealVideo codecs. RealPlayers are available for Windows, Macintosh, Linux, Unix, mobile phones, portable devices, set top boxes, DVD players and even gaming consoles.
The fist version of the software was developed in 1995 by RealNetworks and went out under the name of RealAudio Player. Since then, versions have followed, one after the other, with the least one being RealPlayer 10.5. At the official website - http://www.real.com you can download a free version (with limited capabilities) or purchase the full one called RealPlayer Plus for US$19.99 one-time fee. The exact link where you can buy and download the product is http://www.real.com/playerplus/index.html.
An interesting fact about Real Player is that it is the first player ever, to utilize the web-streaming technology for both audio and video, allowing people to play the file while downloading it. There is now a large number of websites serving RealAudio and RealVideo content helping this software gain further popularity and to ultimately become the leader in the extremely intense race between the media players.
The minimum system requirements are: 350MHz Intel Pentium II processor or equivalent, 64MB of RAM(128MB on Windows XP or later), 52MB available disk space, 28.8Kbps modem (audio only), 16-bit sound card and speakers, 65,000-color video display card set to display at 800x600 (video), Windows 98SE, Windows ME, Windows 2000 with Service Pack 2 or later, or Windows XP, IE 5.0 or later.
