What is DCDi by FAROUDJA?

The new A/V receivers can convert video signal format to HDMI for display on a compatible monitor, whether the signals are from Composite, S-Video, or Component input. In this process, the unit converts interlaced pictures to progressive ones -- a process known as “IP conversion” -using “DCDi by FAROUDJA”, a renowned, high-performance device. It features a host of advanced technologies for noise reduction and reproduction of high-definition pictures, including:

3D Deinterlacer

Film Mode: Recreates the original film frames by

accurately blending the fields back together in progressive scanning -- for images free of motion artifacts and with full vertical resolution.

RX-D702 RX-D402

*Also applies to RX-D401

Video Mode: Delivers pictures from video sources by eliminating jagged edges on diagonal lines.

3D Noise Reduction

Filters out the noise temporally, without smearing or ghosting of moving objects in the image.

3D Cross Color

Suppression

Prevents leakage of color information to chroma channels.

Fleshtone Adaptive

Noise Reduction

Controls noise reduction coefficient to deliver optimum human flesh color.

3D Deinterlacer

A unique algorithm that identifies all the moving edges in a scene and adjusts the angle of interpolation at each pixel so th at t he int erpol ati o n always follows the edge instead of crossing it, eliminating staircasing or jagged edge artifacts.

Jagged Edges on Diagonal Lines

Smooth diagonal lines are also delivered by the 3D Deinterlacer.

Cross-Color Suppression

While composite signals are decoded, high-frequency luma information leaks into the chroma channel, generating noise that looks like flashing colors or rainbow patterns.

Smooth Diagonal Edges

The Cross-Color Suppression effectively eliminates the noise with high-performance chroma processing.

(1) The 2Mbps high transmission rate using the 2.4GHz band permits transmission of uncompressed

signals for lossless reproduction.

(2) Input signals are free of D/A or A/D conversion until just before output, which prevents

conversion loss.

(3) Use of DSSS (Direct Sequence Spread Spectrum) modulation technology enables transmission of

uncompressed signals with superior resistance against noise, which retains superb sound

quality. (4) Corresponds to 16-bit, 32kHz/44.1kHz/48kHz sampling rates. (5) Almost real-time data transmission -- delay time is only 2msecor less.

User ID Learning Function & Auto Scan

RX-D702

User ID Learning Function

To ensure security, the wirelss USB transmitter and the RX-D702 share a specific “user ID”. This means devices without the same ID cannnot receive signals from the transmitter. And when you replace the transmitter, “User ID Learning Function” would be convenient. This function lets you easily set up a new user ID, so that the unit can receive signals from the new transmitter.

Transmitter

Auto Scan

The Wireless USB additionally features “Auto Scan”, which stops interruption from other signals in the same room. When the system is turned on, this function automatically detects electric waves from other devices -- wireless LAN, for example -- and selects a band that won't be interrupted by the other signals.

When the signal transmission is interfered by other waves while using the unit, simply press and hold the “Channel Key” (on the transmitter) for a few seconds. The transmitter automatically switches the band to a one that won’t be interfered by the waves.

CC Converter -- A JVC-Original Technology for Superior Sound

K2 Processing is the result of a close collaboration among JVC studio engineers, producers and hardware engineers, embodying the elaborate algorithms for a sound quality that is close to the master by professional standards. The CC Converter is one of its applications to improve the sound quality of not only pure audio sources but also compressed files, such as dts, Dolby Digital, and MP3. The CC Converter lets you experience a sound that is truer to the original master than ever. With the RX-D702, front L/R channels are processed by the CC Converter.

Background

RX-D702

Digital audio started with Compact Disc and has since given birth to such super high-fidelity formats as DVD Audio and SACD. There’s another trend in digital audio: compressed data formats. Music distribution over the Internet, silicon audio using compact IC cards, and digital broadcast by satellite -- all these formats take advantage of audio compression technology. This means there are two diverging trends in digital audio -- higher fidelity and higher compression.

JVC is not only a hardware maker but also a software producer as well, so there has been a close collaboration between the hardware engineers and studio engineers for all aspects of digital sound production. “K2 Processing Technology” is one of the many improvements developed by this collaboration to achieve higher sound quality. It was implemented as the “Extended K2 Processing,” a critically acclaimed application to pure audio. The CC Converter is an adaptation of this technology for compressed music. Therefore, it improves the sound quality of both hi-fi sources such as CD and DVD (Linear Mode) and compressed music formats including MP3 and WMA (Compression Mode), benefiting a wide range of digital audio contents.

Problems with Digital Conversion

In digital audio, music is processed in digital form. The music played by musicians in a recording studio or a concert hall is picked up by a microphone and recorded in digital form, to be released for sale as packaged media, including CD. The consumers buy the CD to play on a CD player: the recorded music is converted from digital to analog for playback through an amplifier and speakers. The process of playing digital music involves analog/digital conversion and digital/analog conversion as shown below.

Process of Playing Digital Music

RX-D702

The sound quality of a signal depends on the following two factors when the signal is converted from analog to digital.

• Quantization wordlength (bits), which determines resolution or the expression of music in the amplitude domain.

• Sampling frequency, which determines the frequency response or the expression of music in the frequency domain.
