Addendum

6. 1080p24 Output

This option only applies to the HDMI output at 1080p resolution. Many

Blu-ray discs that originated from theatrical movies are encoded using

24Hz frame rate, the same number of frames per second as the original

theatrical film. If your TV properly supports 1080p 24Hz, smoother

motion can be achieved by enabling 1080p24 output for such discs. The

available options are:
Auto

– Video encoded in 24Hz frame rate will be output as 1080p 24Hz

if the TV informs the player that it can support the 1080p24 signal.
On

– Video encoded in 24Hz frame rate will be output as 1080p 24Hz

without regard to whether the TV can support the 1080p24 signal or

not. This is useful if the TV can actually support 1080p24 but does not

properly state its capability. Please note that if the TV cannot support

1080p24, selecting this option will result in no video.
Off (default)

– Video encoded in 24Hz frame rate will be converted to

50Hz (PAL) or 60Hz (NTSC)

7. Colour Space

To select the colour space for the HDMI output. The available options

are:
Auto (Recommended)

– The player checks with the display device to

automatically determine what colour space to use. If the display device

supports YCbCr 4:4:4, then it will be used to avoid extra colour space

conversion.
RGB Video Level

– The HDMI output uses RGB colour space and

normal signal range suitable for video displays. Video signal level below

reference black or above reference white in the original content is

preserved without clipping or alteration.
YCbCr 4:4:4

– The HDMI output uses YCbCr 4:4:4 colour space.

YCbCr 4:2:2

– The HDMI output uses YCbCr 4:2:2 colour space. Generally

this is the colour space that is closest to the colour space encoded on

the discs. (All discs are encoded in YCbCr 4:2:0 colour space, and the

video decoder decodes it into YCbCr 4:2:2.)

8. HDMI Deep Color

To select Deep Colour modes for the HDMI output. Deep Colour is an

OPTION for some TVs or projectors that feature HDMI v1.3 or higher

input.
Normally, each pixel of the video image is transmitted using 24-bit data

(8-bit per channel for R, G, B or Y, Cb, Cr). If Deep Colour is supported

on your TV each pixel of the video image can be transmitted using 30-bit

(10-bit per channel) or 36-bit (12-bit per channel) data. The increased bit

depth should result in smoother colour transitions and better gradients

for better picture quality.
For BD discs with native deep colour on them the extra information will

be passed to the TV. For up-scaled content such as DVDs the deep colour

output will be interpolated but can still result in a smoother picture. The

dithering/limiting options allow discs with deep colour content to be sent

to TVs with limited deep colour support.
Dithering is a way to softly limit any extra colour information in the source

material that the display cannot handle by adding ‘noise’ to prevent an

abrupt step in the levels.
30 Bits

– Use the 30-bit per pixel Deep Colour mode and hard limit

output at 8 bits per colour.
36 Bits

– Always use the maximum 36-bit per pixel Deep Colour mode

for the output.
Off

– Do not use Deep Colour, hard limit output at 8 bits per colour.

9. Display Options

To configure the options for displaying on-screen information. The

following display options are available:
Subtitle Shift

– To set the display position for subtitles. When the

“Subtitle Shift” is set at 0 (default), subtitles are displayed at the original

position as specified on the disc. When it is set at a value between 1

and 5, subtitles are shifted up. When it is set at a value between -1

and -5, subtitles are shifted down. This feature is helpful for instance

to customers using a 2.35:1 “Constant Image Height” video projection

system. Subtitles can be shifted to the active video area so they do not

get cut off.
OSD Position

– To set the display position for on-screen display (OSD).

When the “OSD Position” is set at 0, OSD is shown at the top and bottom

of the video screen. When it is set at a value between 1 and 5, OSD

is shifted towards the vertical center line of the video screen. Similar

to the subtitle shift setting above, the “OSD Position” feature is helpful

to customers using a 2.35:1 “Constant Image Height” video projection

system.
OSD Mode

– To select how long the on-screen display information, such

as elapsed or remaining time, stays on the TV screen. The available

options are:
Normal – On-screen display information stays on the TV screen until

the user cancels it.

Silent – On-screen display information shows on the TV screen for a few

seconds and then disappears. The front panel display still maintains

the selected display information.

Remaining – On-screen display information stays on the TV screen

until the user cancels it. By default display remaining time instead of

elapsed time.

Angle Mark (on/off)

– To turn on/off the display of an angle mark when a

DVD or Blu-ray Disc with multiple available angles is played. Keeping the

angle mark off avoids distraction from normal movie watching.
PIP Mark (on/off)

– To turn on/off the display of a Picture-in-Picture

mark when a Blu-ray disc with secondary video is played. Keeping the

PIP mark off avoids distraction from normal movie watching.
SAP Mark (on/off)

– To turn on/off the display of a Secondary Audio

Program mark when a Bluray Disc with secondary video and audio is

played. Keeping the SAP mark off avoids distraction from normal movie

watching.
Screen Saver

– To turn on/off the screen saver function. The screen

saver is designed to minimize burn-in concerns for plasma and CRT

display devices. The available options are:
On – After about 3 minutes of inactivity, the player will show an

animated Cambridge Audio logo moving on a black background. This

allows most areas of the screen to rest and gives all areas an equal

opportunity to refresh.

Off – The screen saver will not be activated. Use this option if your TV

does not have a burn-in issue.

Energy Saver – Video output will be turned off after 3 minutes of

inactivity. Many projectors and LCD TVs will go into a standby or sleep

mode and turn off their projection lamp or LCD backlight lamp, thus

saving energy and prolonging the lamp life. When you press any button

on the remote control or the player’s front panel, the screen saver will

be cancelled and video output will be restored. If your TV is already in

standby or sleep mode, you may need to wake up the TV by pressing a

button on its remote or control panel.
