GLOSSARY
Aspect Ratio: This is a description of the width of a video image in
relation to its height. A conventional video screen is four units wide for
every three units of height, making it almost square. Wide-aspect ratio
video displays are 16 units wide for every nine units of height, more like
the screen in a movie theater. The program material on a video disc
may be recorded in either format and, in addition, you may configure
the BDP 1 to play back in either format, depending on the features
recorded on a disc.
Chapter: Blu-ray Disc and DVD programs are divided into chapters and
titles. Chapters are the subsections programmed into a single title on a
disc. Chapters may be compared to the individual tracks on an audio CD.
Press the Disc Menu Button to see a listing of the chapters on a disc.
Component Video: This form of video signal eliminates many of the
artifacts of traditional composite video signals by splitting the signal into
a separate luminance channel (the “Y” signal channel) and two-color
difference signals (the “Pr” and “Pb” signal channels). With a component
video connection, you will see greater picture resolution and eliminate
many picture imperfections, such as the moiré patterns often seen on
check-patterned cloth.
HDCP (High-Bandwidth Digital Content Protection): HDCP is the
specification for protecting digitally encoded content from unauthorized
copying when it is transmitted from a video source to a display using
HDMI or DVI connections. To take advantage of the high-resolution
output of the BDP 1 via its HDMI output, your display must be HDCP-
compliant. All displays with HDMI inputs are HDCP-compliant, but not
all DVI-equipped displays are.
HDMI (High-Definition Multimedia Interface): HDMI is a form of
communication between an audio/video source and a video display or
audio/video receiver. It is capable of passing digital audio and high-
definition digital video using a single cable. With HDMI, the BDP 1 is
capable of outputting high-resolution (720p, 1080i or 1080p) video
and 7.1-channel PCM, Dolby TrueHD or DTS-HD Master Audio digital
audio, with the convenience of a single cable connection.
JPEG Files: JPEG stands for the Joint Photographic Experts Group,
which developed a standard for compressing still images, such as
photographs. JPEG files may be created on a personal computer by
importing images from a digital camera, or scanning printed photographs.
These files may be burned onto a compact disc or stored on a USB
device. The BDP 1 is capable of recognizing JPEG files and enabling
you to view them on your video screen.
MP3 Files: MP3 is an audio compression format that was developed
by the Moving Picture Experts Group as an adjunct to the MPEG-1
video compression format. The main benefit of MP3 is that it reduces
the size of audio files considerably, depending on the amount of
compression selected during the encoding process, enabling you to
store many more songs on one compact disc than in the standard
audio CD format. The BDP 1 is capable of playing MP3 files stored
on a disc or stored on a USB device.
Multiple Angle: Blu-ray Disc and DVD media have the capability to
show up to four different views of the same scene in a program. When
a disc is encoded with multiple-angle information, pressing the Angle
Button will enable you to switch between these different views. Few
discs take advantage of this capability and, when they do, the multiple-
angle technology will only be present for short periods of time. Producers
will usually insert an icon or graphic into the picture to alert you to the
availability of multiple-angle scenes.
Resume: The Stop Button on the BDP 1 works differently from that on
a CD player. On a traditional CD player, when you press the Stop Button,
the unit does just that – it stops playback; then, the next time you press
the Play Button, the disc starts from the beginning.
With the BDP 1, however, you have two options when playing most
discs. Pressing the Stop Button once will stop the playback, but it
actually puts the unit in the Resume mode. This means that when you
press the Play Button the next time, the disc will resume playback from
the point on the disc where the Stop Button was pressed. This is helpful
if you are watching a movie and must interrupt your viewing session
but wish to pick up where you left off.
Pressing the Stop Button twice will stop the machine in a traditional
manner and, when the disc is played again, it will start from the
beginning.
Title: For Blu-ray Disc or DVD media, a title is defined as an entire
movie or program. There may be as many chapters within a title as the
producers decide to include. Most discs include only one title, but some
may have more than one, to give you a “Double Feature” presentation or
to include other special features.
Video Output Resolution: This is the scan rate of the video signal.
Analog composite and S-video signals are displayed at a maximum rate
of “480i”. The “480” represents the number of horizontal scan lines, and
the “i” stands for “interlaced”. With interlaced scanning, half the lines in
a frame are displayed at a time: e.g., all of the even-numbered rows,
then all of the odd-numbered rows.
The greater capacity of component video allows for higher scan rates,
and for progressive scanning. Unlike interlaced scanning, progressive-
scan video signals are displayed one full frame at a time, with all rows
scanned at each “refresh”. This results in a brighter image, with greater
clarity and reduced distortion. The BDP 1 is capable of outputting 480p,
720p and 1080i video signals through its component video outputs.
The HDMI connection carries video in digital form, and the even greater
capacity allows for scan rates of up to 1080p. With the advent of high-
resolution video, the frame refresh rate (or the number of times per
second a frame is displayed) has become an important consideration
in achieving superior performance. Analog video is displayed at a rate
of “60i”, or 60 times per second, interlaced. Digital video supports a
rate of 24p, or 24 frames per second, progressive, which matches film,
delivering a pleasing cinematic look. Blu-ray Disc and DVD media are
stored at 24p. If your video display is capable of handling 1080/24p
video, the BDP 1 will output compatible source materials at that rate
through the HDMI Output.
