About IEEE1394
IEEE1394 is an international standard established by the Institute of Electrical and Electronics Engineers (IEEE) of the United States.
The AVR-5805 can be connected to an IEEE1394 compatible device using an IEEE1394 cable to enable digital transfer of multi-channel audio
sources (DVD Audio discs, Super Audio CDs, etc.) with a single cable.
•The AVR-5805’s transfer format is compatible with A&M protocol.
In addition to A&M protocol, IEEE1394 transfer formats also include MPEG-TS, DV, etc.
•The AVR-5805 is compatible with a data transfer speed of up to S400.
The IEEE1394 maximum data transfer speeds are defined as approximately 100, 200 or 400 Mbps, expressed respectively as S100, S200 and
S400.
•The AVR-5805 is compatible with the DTCP (Digital Transmission Content Protection) system.
2Copyright protection system
In order to play the sound of DVD Audio discs, Super Audio CDs or DVDs (aside from freely copiable discs) using IEEE1394 connections,
both the player and receiver must be compatible with the DTCP (Digital Transmission Content Protection) system.
DTCP is a copy protection technology that involves data encryption and authentication of the other device. Refer to your player’s operating
instructions.
The AVR-5805’s IEEE1394 device interface is designed based on the standards below.
1) IEEE Std. 1394a-2000, Standard for High Performance Serial Bus
2) Audio and Music Data Transmission Protocol 2.0
It is compatible with IEC60958 bit stream, DVD-Audio and SACD within AM824 sequence adaptation layers within these standards.
DENON LINK (DENON Digital Link)
High-grade LPCM 24-bit, 96-kHz, 6-channel or 24-bit, 192-kHz, 2-channel digital input is possible when the AVR-5805 is connected via a shielded
twisted pair (STP) cable to a Denon DVD player that supports Denon Digital Link, Since Denon Digital Link uses low-voltage differential signaling
(LVDS), transfer capabilities of greater than 1.2 Gbps at a differential voltage of approximately 0.3Vpp are possible.
About HDMI
“HDMI” is the abbreviation of “High Definition Multimedia Interface”.
This is a digital interface standard for next generation TVs developed based on the DVI (Digital Visual Interface) used for computer displays, etc.,
and optimized for use in non-professional equipment. With it, non-compressed digital video and multi-channel audio signals can be transferred
with a single connector, eliminating the need to use separate cables for the picture and sound and making it possible to make connectors smaller.
HDMI is also compatible with HDCP (High-bandwidth Digital Contents Protection), a technology for protecting copyrights that encrypts digital
video signals in the same was as with DVI.
Advanced AL24 Processing
2Equipped with “Advanced AL24 Processing” – time base area data quantity extension
In addition to “AL24 Processing Plus”, the conventional bit extension technology, the PCM signal (CD/digital) playback system also includes
the newly developed “Advanced AL24 Processing”, a unique high speed signal detection and processing technology that greatly improves
the amount of data in the time base area. In addition to extension of the original 16-bit data into 24 bits, “Advanced AL24 Processing”
conducts data interpolation on the time axis, in other words up-convert sampling, to achieve natural interpolation processing without harming
the original data. In addition, the digital filter offers expanded flexibility, including pulse response with no ringing. Optimum filtering
processing is performed even for pulsive music data and attack sounds. All this makes it possible to recreate the delicate nuances of the
music and such space information as the positions of the performers, the width, height and depth of the place of the performance (stage),
and so on.
