1080p24 Output, Colour Space | Cambridge Audio AP26149/1 specs

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.
