Half SBS Vs. Full SBS: What's The Difference?
As of 2017, LG and Sony offered 3D TVs, and the 3D VR headset such as Google Daydream View, Oculus Rift, Samsung Gear VR enable you to watch 3D contents on your protable devices. Also, most video projector brands still offer the 3D viewing option.
In addition, there is a lot of great content for those that wish to take advantage if the 3D viewing experience at home.
However, getting into 3D is more than just buying the right TV, headset or video projector, although that is the starting point. Check out what the the difference between the half SBS 3D and full SBS 3D and how to make all of your Blu-ray disc, DVD disc and videos files is available to watch with 3D effect.
What Is 3D SBS?
SBS 3D, short for side-by-side 3D (left and right 3D), is a popular choice and widely used 3D format besides frame-sequential 3D when it comes to airing 3D content over 3D TV, video protjector or VR headset.
In side-by-side 3D, a full 1080p or 720p frame is intended for both eyes at the same time with two halves on the left and right, and the entire frame for the left eye and right eye respectively scaled down horizontally to fit the left-half and right-half of the frame. For example, for a 720p content (resolution of 1280 x 720), the frame for the left eye will be 640 x 720 and the frame for the right eye will also be at a 640×720 resolution.
When such SBS signal is received by 3D device, the 3D device will split each frame to extract the frame for each eye, and then will rescale these individual frames to a full HD resolution. Then these individual frames will then be displayed alternately in a frame-sequential manner which is in sync with your active shutter 3D glasses.
What the Difference Between Half SBS 3D and Full SBS 3D
Half Side-by-Side (SBS), means the left and right views of a 3D video are subsampled at half resolution and you get a backwards compatible full frame.
Example: Say, each view is 1920×1080
subsample to 960 x 1080, put them side by side and now you have a 3D 1920×1080 frame.
Full SBS, means you transmit both views at full resolution; better quality, but bigger file.
The half-SBS was the necessary format for YouTube 3D, until it added the capability for half OU: half Over and Under. This is superior for 3D stereo perception because the full HD horizontal resolution is retained, and the vertical resolution is interlaced between right and left, adding up to a perception of fuller resolution than the actual halving would suggest.
Half-SBS = (960+960) 1920 x 1080P
Full-SBS = (1920+1920) 3840 x 1080P
3DBD Bluray 1920 x 1080 Left + 1920 x 1080 Right,
= 3840 x 1080 Full-SBS, but Only can be played
from BD/ BD25/ BD50 via Bluray Player
Now with Passive TV’s in 2D they are Full HD 1920 x1080P
In 3D because of the Polarized Glasses you only see,
Half the Horizontal Res of Left Eye and Half for Right Eye 540P
Half-SBS on Passive is 960 x 540 (Left) + 960 x 540 (Right)
Half-SBS on Active is 960 x 1080P (Left) + 960 x 1080P (Right)
Full Over/Under (aka) Top & Bottom
Full – 1920 x (1080+1080) 2160
Half – 1920 x (540+540) 1080P
