Blu-ray Disc Overview: Blu-ray Disc (BD) is a new
high-definition disc format designed to take advantage of today's high quality
HDTVs. The resolution is up to 1920 x 1080 (1080p) and the data transfer rate is
up to 54 mbps. Blu-ray Disc discs and players offer several advantages over the
standard DVD format:
- Better Picture Quality: Blu-ray Disc is a true
high-definition format offering video at 720p, 1080i, or 1080p resolution.
While standard DVDs look very good on an HDTV, they don't provide a
high-definition signal (not even when you use an up-converting DVD player).
Blu-ray Disc delivers an extraordinarily sharp, clean, detailed picture,
with deeper, richer colors.
- Better Sound Quality: In addition to the same
multi-channel sound formats you're accustomed to with DVD (Dolby Digital and
DTS), Blu-ray Disc offers Dolby TrueHD, Dolby Digital Plus, DTS-HD Master
Audio, DTS-HD High Resolution, and uncompressed 7.1 channel PCM.
- Greater Storage Capacity: What makes Blu-ray Disc's
superior picture and sound possible is the much higher storage capacity of
Blu-ray Disc discs. A single-layer Blu-ray Disc can hold 25 gigabytes of
data, over five times the amount a standard DVD can hold. Dual-layer Blu-ray
Discs hold 50 gigabytes, which equates to nine hours of High Definition or
23 hours of Standard Definition video, plus high-resolution multi-channel
audio and the added features and material that require multiple discs with
- Backward Compatible: To ensure backward-compatibility
with your existing library of discs, Blu-ray Disc players use a dual-laser
mechanism: a blue laser for playing high-definition Blu-ray Discs, and a
conventional red laser for playing DVDs and audio CDs.
Note: Like DVD, BD uses region codes. The region code on
your disc must match the region code on your player, otherwise the disc will
not play. The 651BD is Blu-ray region A and DVD region 1. Blu-ray Disc uses
the Advanced Access Content System (AACS) to prevent unauthorized recording
Firmware Updates: As Blu-Ray technology continues to evolve,
new disc types with enhanced functionality will become available. In order for
you to enjoy this new functionality, you will likely be required to update the
firmware in your player. These firmware updates will become available for
downloading from the Internet, via the player's Ethernet port.
Note: The tested
Blu-ray player contained firmware version 751BDCU-10-0721 and required an
immediate firmware version update (as of 7/12/2012). Visit Cambridge Audio's
Support Site for the latest firmware updates.
AVCHD Playback: The 651BD will play home videos recorded in
AVCHD (MPEG-4 AVC/H.264), a high definition digital video camera format used to
record in high definition or standard definition on DVD-R/RW or DVD+R/RW discs.
AVCHD can also be played from a USB flash memory device connected to the front
SACD: Super Audio CD use a technology called Direct Stream
Digital (DSD) to convert music into a digital signal that can be stored on a
disc. Compared to the traditional PCM method (the technology used for CD), DSD
offers a much higher resolution by following more closely the original waveform
of music. With a frequency response of over 100kHz and a dynamic range over
120dB across the audible frequency range - some 64 times higher resolution then
CD - Super Audio CD offers music reproduction that reveals details you just
cannot hear on a normal CD.
DVD Audio: DVD Audio is a digital audio format that delivers
high-fidelity audio content on a DVD disc. DVD-Audio supports bit depths up to
24-bit and sample rates up to 192 kHz, while CD audio is only 16-bit, 44.1 kHz.
Compared to CD audio discs, DVD Audio offers considerable more music storage,
higher audio quality, and additional audio channels for surround sound.
DVD-Audio offers many possible configurations of audio channels (up to
5.1-channel surround sound).
HDCD: HDCD is a variation of the existing CD standard. By extending
the information stored in the CD signal by 4-bits (CDs are based on 16-bit audio
technology) to 20-bits, HDCD can extend the sonic capacity of current CD
technology to new standards.
Kodak Picture CD: This unit can also play JPEG files stored
on a Kodak Picture CD; you can enjoy pictures on the television by playing back
MP3/WMA Playback: The Cambridge Audio Blu-ray player will
play MP3/WMA audio files written to CD-R/RW, DVD-R/RW, and DVD+R/RW discs.
Video Outputs: The Cambridge Audio 651BD is equipped with
the following high-definition and standard definition video outputs.
- Dual HDMI 1.4a Outputs: With twin HDMI outputs, the 651BD can
deliver the same video signal to two display simultaneously. Both HDMI
outputs are fully compatible with the HDMI 1.4 standard for 3D, Deep Color,
& xvYCC support. The HDMI outputs support 480i, 480p,
720p, 1080i, and 1080p.
- Component Video Output: The 651BD features one
component video output, capable of passing a progressive scan signal or an
interlaced video signal. The component video output supports 480i, 480p,
720p, and 1080i.
- Composite Video Output: The Blu-ray disc player
features one Composite video output that supports 480i.
1080p/24Hz Compatible: Movies are typically recorded on film with a
frame rate of 24 frames per second. When a movie is transferred to Blu-ray Disc
at 24 frames-per-second ,the 651BD will output that signal to the TV (if the TV
will accept the 1080p/24 format) with no need for conversion.
Marvell QDEO Video Scaler: The primary HDMI output also features a
high quality Marvell QDEO video scaler (DE2750) with motion adaptive noise
reduction for quiet and natural video, free from noise and artifacts. As well as
stunning performance with Blu-ray discs, the 651BD delivers unbeatable picture
quality from existing DVDs, which can be up-scaled to 1080p resolution.
Note: Video up-conversion over the component output
is only available for unencrypted discs such as home video and
consumer-created contents. Most commercially pressed DVD discs are CSS-encrypted
and will be limited to 480i/480p resolution. This restriction applies to the
component output only. The HDMI output is protected with HDCP and has no
Source Direct: The 651BD supports a special "Source Direct"
output resolution on its HDMI output. This resolution is recommended for use
with external video processors or high-end TVs with high quality scalers. In
"Source Direct" mode, the player works as a "transport". It decodes video from
the discs and then sends the raw video signal in its native resolution and
format, without extra processing, to the external video processor or TV. The
actual output resolution thus varies by content.
|Blu-ray TV Shows & Concerts||1080i|
|SACD or DVD-Audio||1080i|
3D-Ready: The Cambridge Audio 651BD lets you enjoy 3D
Blu-ray disc movies in full HD 1080p. 3D viewing requires compatible 3D content,
3D-ready HDTV, 3D emitter & glasses, and a high-speed HDMI cable (supporting at
least 10.2 Gbps) connection. The Blu-ray player offer three 3D video output
- Auto: Outputs 3D if supported both by the disc content and the
display. The player automatically checks for the existence of 3D content on
the disc and the 3D compatibility of the TV or projector. If both are
qualified, the player sends 3D video from its HDMI output terminals,
otherwise only 2D video is sent out. 3D-compatible glasses are
required with your 3D TV.
- Forced: Always outputs 3D video format for 3D Blu-ray discs. You
might experience a black screen (no video output) if your TV is not 3D
- Off: Always outputs 2D video format, even when 3D video exists on
the disc. This can guarantee the video quality in case that your TV is not
3D compatible, or some necessary part (such as the 3D glasses) is missing.
Note: You can also set the diagonal screen size of your HDTV.
Deep Color: The HDMI output supports Deep Color, increasing the number
of bits available for transmission, meaning more colors. This results in much
greater color fidelity, smooth tonal transitions, and ultra-fine gradations
between colors. It also enables many times more shades of gray, for higher
xvYCC: xvYCC color space reproduces a greater range of color
than before, showing almost all of the colors that the human eye can detect.
Aspect Ratio: Use this setting to select the screen format to fit your

Digital /DTS decoder with multi-channel analog outputs (7.1ch). In addition
to the 7.1-channel analog outputs, the unit features a stereo audio output
for connecting to a stereo analog input on a TV or receiver. Even when the
source audio is multi-channel (Dolby Digital, DTS, DVD-Audio, SACD), these
jacks will output a downmixed 2-channel signal.
- Digital Audio Output: This unit features a coaxial
(RCA) and optical (toslink) digital audio output connection. The coaxial or
optical digital audio output can be connected to an A/V receiver, amplifier,
surround decoder (Dolby Digital, DTS), or other component. The digital audio
outputs support transfer of Dolby Digital and/or DTS sound tracks, or
down-mix surround bitstreams to 2-channel PCM audio.
Speaker Management: In the Speaker Management menu you can configure
speaker settings such as down-mix mode, number of speakers, their distance,
size, trim level, and crossover frequency.
- Configuration: Choose from Down Mix (converts multi-channel audio
to a lesser number of channels), LT/RT (the center and surround channels are
decoded and then matrix encoded into the two front channels), Stereo
(down-mixes multi-channel audio to 2-channel stereo), 5.1ch (enables 5.1ch
decoded audio output), or 7.1ch (enables 7.1ch decoded audio output).
- Size: The speaker size parameter sets bass filter control for the
speakers. Choose Large or Small for your speakers and On or Off for your
- Crossover: When the speaker size is set to "Small", bass
frequencies are not passed to the speakers to reduce possible distortion:
bass frequencies will instead be redirected to the subwoofer. The available
options are 40, 60, 80, 90, 100, 110, 120, 150, 200, and 250Hz.
- Distance: The speaker distance parameters sets delay control for
the corresponding audio channel. This delay is used to compensate for the
audio propagation time difference caused by the placements of speakers of
different distances from the listening position.
- Trim: The speaker trim level parameters sets the volume of each
individual channel. For most accurate results, it is recommended that you
use test tones from a calibration disc, such as Digital Video Essentials HD
Basics, and a SPL (Sound Pressure Level) meter. The trim level can be set to
+/- 10dB in 0.5dB increments.
Dynamic Range Control (DRC): DRC can smooth out the sonic peaks and
valleys common with wide-range digital audio. Enabling DRC may make low level
audio more audible during low-level listening. Turning off DRC restores the
sonic energy present in the original recording.
Ethernet (LAN) Port: The Cambridge Audio 651BD is fitted with a
rear-panel R-J45 Ethernet port (10BASE-T/100BASE-TX) to connect to your home's
