- RealMedia - One of the most popular formats for streaming content on the Internet, RealMedia includes the RealAudio codec for sound clips and RealVideo codec for movies. RealAudio and RealVideo files are often given the common RealMedia ".RM" file extension. RealMedia is a container format that's often heavily compressed for streaming over dial-up Internet connections. RealMedia variable bitrate (RMVB) has been developed for VBR streaming files. RealMedia is a digital sound and video file format that is the registered trademark of RealNetworks. This format is typically used to stream media through the net. It can be played with the RealOne player or with other media players using the Real Alternative codec.
- RealVideo - RealVideo is a streaming video format developed by RealNetworks. RealVideo is probably the most popular streaming video format in the world, although its quality is horrible if you compare it to MPEG4-based formats like DivX or WMV.
- Region codes - Region codes in this instance mean flags implemented in DVD-Video discs that determine the geographic area where the DVD-Video disc is being sold and where it can be watched. These codes ensure that one country doesn't get a DVD movie before the same movie is out in that country's theatres. In their corporate omniscience, movie studios have carved the planet into regions with each region having a specific code.
All DVD players and discs have region codes. A DVD player and disc must be of the same region or the disc will not play. If you want to watch movies from other countries, you need a multiregion DVD player. This will allow you to play any disc from any region.
The region controls are also implemented in PC's DVD-ROM drivers, normally in three levels. First of all, if the DVD-ROM driver is manufactured after 1st of January, 2000, the driver itself has physical locks implemented in it to permit playback of only specific region code. Secondly, all newer operating systems, including Windows 2000 and Windows XP, have region control measurements built-in. And finally, the DVD player software, such as WinDVD or PowerDVD, have region control measurements built-in.
- ripping - also called digital audio extraction, this is the process of taking CD audio and recording it to a computer in any file format. When the transfer is from CD to MP3, the process is both ripping and encoding.
- RM (.rm) - "Real Media", fie type from Real Networks.
- RMVB - Rmvb is an abbreviation for Real Media variable bitrate. It is a type of video file, playable with RealPlayer from RealNetworks.
- SDII (Sound Designer II) An audio format for Macintosh operating systems which is often employed by pro-quality sound editing software applications. SDII files, like AIFF and WAV files, are capable of storing uncompressed CD-quality audio.
- SHN (Shorten) Shorten is a lossless form of compression for digital audio. An SHN file is only about half the size of its original WAV or AIFF source. Unlike lossy audio codecs (such as MP3, WMA, etc.), SHN is capable of reproducing the original audio signal in its entirety, without removing frequencies. Because of this, SHN offers significantly better sound quality than MP3. However, since SHN files are significantly larger than MP3 files, this format isn't nearly as convenient when it comes to storage space or download time.
