  DivX Video-Playback

  DivX is an advanced digital media format. DivX lets you play, create and share digital video by turning large video files into much more streamlined DivX files. Using a DivX codec (short for compressor/decompressor) to compress the video to a convenient size without losing any noticeable quality and play those videos back on almost any device. For example, the DivX codec can compress an MPEG-2/DVD file to nearly one-tenth its original size.

  Dolby Digital-Decoder

  Dolby Digital is the multi-channel digital signal format developed by Dolby Laboratories. Dolby Digital consists of up to "5.1" channels - front left, front right, center, surround left, surround right and an additional channel exclusively reserved for additional deep bass sound effects (the Low Frequency Effects - LFE - channel, also called the ".1" channel, containing bass frequencies of up to 120Hz).
  
  Unlike the analog Dolby Pro Logic format, Dolby Digital's main channels can all contain full range sound information, from the lowest bass, up to the highest frequencies - 22kHz. The signals within each channel are distinct from the others, allowing pinpoint sound imaging and Dolby Digital offers tremendous dynamic range from the most powerful sound effects to the quietest, softest sounds, free from noise and distortion.

  DTS-Decoder

  A data compression method developed by Digital Threater Systems that takes six channels of audio (5.1) and folds them into a single digital bitstream. This differs from Dolby Digital in that the data rate is a somewhat higher 1.4 Mbs, which represents a compression ratio of about 4 to 1.In order to take advantage of this DVD feature, a DTS decoder is required. DTS decoders are installed internally in Denon players and A/V recievers.

  DVD Video

  A single-sided, single-layer Digital Versatile Disc (DVD) Video, holds approximately 133 minutes of full-motion video using MPEG-2 compression. The visual quality is that of a LaserDisc, which is superior to a VHS tape. The 133 minutes is an approximate number, because compression is not fixed, but is based upon the amount of motion taking place.
  
  DVD-Video discs can be recorded on both sides, and two layers per side can be used, thus up to four two-hour movies can be contained on a single volume. DVD-Video supports Dolby Digital surround sound, which provides five discrete channels of CD-quality audio plus a subwoofer (5.1 channel).

  DVD - Audio

  DVD-Audio (DVD-A) is a Digital Versatile Disc (DVD) format, that is specifically designed to hold audio data, and particularly, high-quality music. The DVD-A format is said to provide at least twice the sound quality of audio CD on disks that can contain up to seven times as much information. Almost all of the space on a DVD video disc is devoted to containing video data. As a consequence, the space allotted to audio data, such as a Dolby Digital 5.1 soundtrack, is severely limited. DVD-A also provides more complexity of sound by increasing the sampling rateand the frequency range beyond what is possible for the space limitations of CDs and DVD-Video. DVD-Audio is 24-bit, with a sampling rate of 96 kHz; in comparison, DVD-Video soundtrack is 16-bit, with a sampling rate of 48 kHz, and standard audio CD is 16-bit, with a sampling rate of 44.1 kHz.
  
  Although DVD-A is designed for music, it can also contain other data, so that - similarly to enhanced CD - it can provide the listener with extra information, such as liner notes and images. DVD-A is backed by most of the industry as the technology that will replace the standard audio CD. The major exception is SACD Super Audio CD, which provides similar audio quality. Like DVD-A, SACD offers 5.1 channel surround sound in addition to 2-channel stereo. Both formats improve the complexity of sound by increasing bit rates and sampling frequencies, and can be played

  HDMI-output (HDCP)

  HDMI (high definition multimedia interface), a new connector that bases itself on the DVI-HDCP model. HDMI supports uncompressed high definition video plus multi-channel audio in a single cable using a smaller connector that eliminates the need for multiple cables in home entertainment systems, simplifying installation and eliminating cross technology confusion. It transmits uncompressed digital video so that the picture maintains a high quality of color depth, brightness and contrast. It also supports Consumer Electronics Control (CEC) based on the AV.link protocol so it can be controlled with a universal remote that is used with multiple HDMI sources such as Denon DVD players. HDMI supports bi-directional coommunciation between devices, allowing DVD players to communicate with Plasma's, LCD screens and Projectors, as long as they are HDCP compatible.
  The HDMI connection supports every uncompressed standard, enhanced and high definition video format ranging from 480I to 480P, 720P, 1080I and 1080P as well as existing PAL formats. It also has the bandwidth to support compressed audio formats such as Dolby Digital, Dolby Digital EX, DTS, DTS EX and uncompressed formats (PCM audio) up to eight channels, up to 192kHz, up to 24-bits.
  
  High Definition Multimedia Interface(HDMI) and High Definition Content Protection (HDCP) is a copyright protection system installed on most Plasmas, LCD's and projectors consisting of a HDMI or DVI input. All Denon DVD players require HDCP compliant displays to be fully compatible. It prohibits the copying of copyrighted material, like onto a VCR or DVD-recorder.

  Kodak Picture CD-compatible

  DVD players that have the Kodak picture CD compatible logo, have been tested and certified by Kodak to ensure that an enjoyable viewing experience is provided. You can view your picture CD on these DVD players.

  MP3 Playback

  A compressed audio format that is popular for downloading across the internet. Files may be recorded on CD-R or CD-RW media for playback in compatible DVD players, audio CD players, and CD-ROM drives. Files are usually named as "*.mp3". Sound quality varies as a function of the recording/encoding bit rate. For a high fidelity home audio system, its recommended to use MP3s encoded at no less than 256 kbps data rate. Anything less would mean too much compression was used at the cost of sound fidelity. See also WMA files compatibility with DVD and CD players.
