The capabilities of a Blu-ray player to do more than just play movies can are categorized by what is known as BD Profiles.
The most capable Blu-ray players will offer features that bring it even with the features set of the now defunct HD DVD player.
The profiles from top to bottom are:
The manufacturer’s suggested retail price.
Typical price in a store or from an online retailer.
Deep Color provides for the use of a greater number of bits to represent colors,
so that the full RGB color space can be utilized, and additional attributes like
the transparency of the color can be represented. Under HDMI version 1.3a, Deep
Color support is optional.
Remote control units that are packaged Blu-ray players fall in to 3 distinct
groups. From best to worse they are:
Standard manufacturer’s warranty, when the device is purchased from an authorized
Most movies are shot using a camera that operates at 24 frames per second, and
are stored on DVD and Blu-ray Discs at the native frame rate. Unfortunately, the
television video format runs at 30 frames per seconds, creating a mismatch. To
deal with this mismatch in the frame rate, DVD and other digital playback
devices have been manipulating the playback rate of content to ensure that
things don’t run faster than intended. The technique used called telecining,
periodically repeats frames to turn 24 frames into 30 frames per second. This
solution is not without its drawbacks, and becomes most evident when there is
motion in objects on screen. What you see on screen is a subtle jerking that can
be annoying to some, particularly with smooth camera pans. An increasing number
of HDTV’s can accept video at 24 frames per second, eliminating the need to
manipulate the information transfer rate.
Up-scaling refers to the technique of manipulating standard DVD recorded at 480
lines of resolution, and digitally rendering its output as though it was
recorded at 720p, 1080i or 1080p high definition video standards.
Blu-ray Disc (BD) and DVD disc can be recorded in several formats. DVD, DVD-R and DVD-RW are the officially endorsed DVD formats.
The + (plus) and the – (minus) formats for DVD are incompatible, (similar to the divide that existed between HD DVD and Blu-ray Disc);
but many DVD players and DVD drives in computers are capable of playing both formats.
Compact Disc or CD can be recorded in many forms:
MP3 or MPEG-1 Audio Layer 3 is a popular digital audio encoding format, use
widely with downloaded music. MP3 uses a compression algorithm that greatly
reduces the amount of storage space needed to store data. Players capable or
decoding the compression algorithm will be able to playback MP3 data recorded to
JPEG is a popular method of compressing photographic images onto disc. Many
people utilize JPEG for long term storage of images shot with digital camera, by
burning it to disk. A Blu-ray Disc capable of playing discs of JPEG files, will
allow you to view your family vacation pictures directly on your HDTV, without
having to connect your computer to the HDTV.
V-Chip or Parental Control, as it is sometimes called, allows the blocking of
television channels or programs. With V-chip technology, programs that have been
rated are encoded with a signal of the rating. If the program’s rating is
outside of the level set on the device, the program is blocked. A password
designated by the device owner, will allow the block to be overidden.
CEC (Consumer Electronic Control) is an optional specification that is part of
HDMI version 1.3a. This specification allows components to discover, communicate
and self configure other CEC components in your system, so that optimal
configuration becomes plug and play.
Dolby Plus is Dolby’s near lossless audio format that provides discrete
multichannel sound output for up to 7.1 channels with Blu-ray media. The
surround sound format also supports multiple programs encoded into a single
bitstream. Dolby Digital Plus decoding is optional for the Blu-ray Format.
Dolby TrueHD is Dolby Laboratories lossless surround sound format. TrueHD
provides sound that is identical to the studio master. Dolby TrueHD decoding is
optional for the Blu-ray format.
DTS-HD Master Audio (formerly called DTS HD) is bit for bit identical to the
studio master. This lossless surround format utilises the DTS 5.1 core and adds
extensions to the audio stream to bring it up to 7.1 discrete channels. DTS
Master Audio is an optional surround format for Blu-ray Disc.
Blu-ray players capable of outputting bitstream audio (the raw encoded audio content) via the HDMI output, will
allow you the option of using the surround decoding processor built into your AV receiver (or other surround sound
processing device). In situation where your AV receiver or external surround processing device has superior decoding
capabilities, HDMI bitstream output (as opposed to multi-channel LPCM) will be your preferred option.
LPCM (Linear Pulse Code Modulation) is a sampling technique for digitally
econding analog audio signals. Support for LPCM is currently mandatory for
Blu-ray Disc players with 5.1 analog outputs will allow for direct connection to
5.1 analog inputs legacy A/V Receivers.
HDMI (High-Definition Multimedia Interface) is the next generation connection
interface, capable of transmitting uncompressed video and audio digital streams.
This connection is the optimum interface for connecting Blu-ray Disc, HD
satellite receivers, HD cable set-top-boxes, video game consoles, AV receivers
and new DVD players.
Simplay HD is a new independent testing program for consumer high definition
equipment that tests HDMI interoperability and connectivity of products. The
program tests high definition components and cables so that end users will be
assured that products will provide the highest quality performance and work
Component Video is the best analog video connection, which transmits video on 3
separate cables; one for color information, one for luminance (or greyscale)
information and the final one for synch. If the component you are connecting to
doesn’t have a digital video connection, this is your best alternative.
SVideo or a Y/C connection as it is sometimes called is a legacy analog video-
only connection that superseded composite video connections. SVideo separates
the video signal into two separate signals; one signal carries the color
information, and the second carries the luminance (greyscale) information.
Composite Video is a low quality legacy video only connection that uses a single
wire to transmit video signals. At the dawn of the home video components market,
this was the only video- only connection available.
Digital Fiber is the optimum audio connection for sending compressed or
uncompressed audio between audio components.
Digital Coaxial is a digital audio connection capable of sending compressed or
uncompressed audio between, audio components. It is equal in sound quality to
its fiber-optic counter-part digital fiber, but it is physically more robust
than digital fiber. However, digital coaxial can suffer from electro-magnetic
Standard computer Ethernet connection.
Energy Star Compliance ensures that the device uses significantly less energy
when it is turned off.
