OFC Power Cord
OFC (oxygen-free copper) has improved electrical properties compared to normal copper. The OFC power cord provides DVD players with a stable power supply.
Off Centre Insulation Feet
The screw holes of these feet are set off-centre to prevent external vibrations reaching the internal circuits.
OLED
OLED or Organic EL. Organic light-emitting diode. A device technology used for display window producing bright and clear pictures.
OLED
Unlike traditional LEDS, an OLED (Organic Light Emitting Diode) screen has no need for a backlight. It uses a special layer that emits light once an electric current is passed through it. This means you get an ultra-thin screen, like the XEL-1 from Sony with its 3mm thin display, which takes up far less space in your home. The new technology saves energy too – without the backlight, it requires less power to run which is far kinder to the environment and your energy bills.
On Screen Contrast
On Screen Contrast highlights the difference between white and black brightness for incredibly rich colours. It’s a measure of the darkest shade (black) and the brightest (white). The higher the contrast ratio, the better the picture quality whatever you’re watching.
On Timer
Enables you to set the TV to switch on, from standby, at a pre-determined time, within twelve hours of the setting time. If there is no command to the TV within one hour, it will switch back to standby.
One-Button Tuning
By pressing the appropriate button, the TV will automatically tune itself.
On-Screen Display
(OSD) The large characters and bar charts of the on-screen display illustrate the entire key operating status of the TV receiver.
On-screen Instruction Manual
The On-screen Instruction Manual makes setting up your BRAVIA TV quick and trouble free. You can view the entire BRAVIA instruction manual on screen whenever you want, so there’s no need to remember where you put the paper manual. Graphics are included to help guide you through connecting devices and setting up your TV just the way you want it.
OPC
(Optimum Recording Control) Checks the tape condition before recording and ensures the best possible picture quality.
OpenMG®
Copyright protection technology including Digital Rights Management that allows three key functions: Music download through multiple electronic music distribution platforms The ability to play back music files and rip CD files to PC (OpenMG® Jukebox) Transfer of contents securely from PCs to portable devices
Operation System
The basic controlling software of a computer. Common operating systems include DOS, Microsoft® Windows® 95/98/2000/XP and Windows NT®.
Optical and Coaxial Digital Audio Outputs
In addition to two sets of analogue audio output terminals, Sony DVD players are equipped with coaxial and optical digital audio terminals. These provide connection, without loss of quality, to any type of MPEG-2/Dolby® Digital processor.
Optical Viewfinder
Optical Viewfinder is used in bright sunshine or low light conditions when the LCD may be difficult to see. It can also be used instead of the LCD to reduce power consumption.
Optical Zoom
Push-button operation allows you to zoom in optically i.e., by manipulation of the lens' focal length.
Optical Zoom
Optical zoom magnifies distant subjects for clear, detailed close-ups. Image quality is superior to digital zoom that enlarges the central portion of the picture with a loss of overall detail and definition.
Organic LED
Unlike traditional LEDS, an OLED (Organic Light Emitting Diode) screen has no need for a backlight. It uses a special layer that emits light once an electric current is passed through it. This means you get an ultra-thin screen, like the XEL-1 from Sony with its 3mm thin display, which takes up far less space in your home. The new technology saves energy too – without the backlight, it requires less power to run which is far kinder to the environment and your energy bills.
OSD
(on-screen display) A stylish on-screen display, viewable via a connected TV / projector device to operate and adjust your home cinema system.
Overwriting capability
The performance index (whether recording marks are well written) of the recording properties is called “jitter.” Ordinarily, jitter rapidly worsens after a certain number of overwrite cycles due to recording layer deterioration. This is why Sony developed a durable recording layer. Jitter hardly rises even after repeated overwrites, resulting in stable recording/playback.
