  Hollywood Quality Video (HQV)

  Silicon Optix (the company behind the Realta chip) and Teranex (the company behind high definition professional broadcasting platforms) enable a new benchmark standard of video excellence called Hollywood Quality Video. Teranex‘s broadcasting platform has been integrated into the Realta chip. Teranex’s software algorithms, which have been refined over 100,000 hours of content verification and are recongnised in the industry for a very high level of quality, have been incorporated to run on Realta.
  
  Realta’s architecture for the HQV chip includes the industry’s first fully software programmable video array processor capable of performing over 1 trillion operations per second, an Image Fidelity Enhancement Engine and end-to-end true 10-bit image processing. These core technologies combine together to enable the simultaneous processing of dual high-definition image streams, delivering HQV into home entertainment and professional video display products. The Denon DVD-A1XV is the first DVD player for the home entertainment market to incorperate HQV technology.

  Advanced AL24 Processing

  The acclaimed Advanced AL24 DSP processing improves the fidelity of high resolution stereo PCM sources such as CD and DVD (up to 192kHz sampling frequencies), by sophisticated DSP processing algorithms that improves low level detail and enhances fidelity by upsampling and adaptive filtering techniques. Advanced AL24 also provides increased dynamic range and spatial information, bringing out all the nuances with optimum clarity and natural fidelity.

  AL24 Processing Plus

  Denon has further developed its proprietary AL24 Processiing, an analog waveform reproduction technology, to support the 192-kHz sampling frequency of DVD-Audio. This new technology, called AL24 Processing Plus, thoroughly suppresses quantization noise with D/A conversion of LPCM signals to reproduce the low-level signals with optimum clarity that brings out all the delicate nuances of the music. In high-end models, AL24 Processing Plus for all channels.

  Audio Delay Function

  This is a function for delaying the audio signal with respect to the video signal.

  DENON LINK

  Connected via a shielded twisted pair (STP) RJ-45 fitted cable to a Denon Link-compliant A/V amplifier, the balanced signal transfer offers lower voltage than coaxial or unbalanced cables. Since DENON Link is far less susceptible to radiated noise, it ensures the highest level of signal transfer. The DENON Link interface is able to transfer high grade LPCM 24-bit, 192kHz, 2-channel and 96kHz, 24-bit, multi-channel digital output. Since Denon Digital Link uses low-voltage differential signaling (LVDS), transfer capabilities of greater than 1.2 Gbps at a differential voltage of approximately 0.3 Vpp are possible.

  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

  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).

  HDCD-Decoder

  HDCD-encoded CDs are encoded with 20 bits of real musical information, as compared with 16 bits for all other CDs. HDCD overcomes the limitation of the 16-bit CD format by using a sophisticated system to encode the additional 4 bits onto the CD while remaining completely compatible with the existing CD format. HDCD provides more dynamic range, a more focused 3-D soundstage, and extremely natural vocal and musical timbre. With HDCD, you get the body, depth, and emotion of the original performance not a flat, digital imitation.

  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.

  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.

  Noise Shaped Video (NSV)

  The NSV feature works in the digital domain to reduce noise in the video signal frequency band in order to enhance video signal linearity.
