INTRODUCTION3D television is tv that conveys depth
perception to the viewer by employing techniques such as stereoscopic display, multi-view display, 2D-plus-depth, or any other form of 3D display
3D televisions shipments have totaled 41.45 million units in 2012, compared with 24.14 in 2011 and 2.26 in 2010.
ADVANCES in 3D digital technologies Dramatic increase in the number of 3DTV’s
Moving Picture Experts Group (MPEG), SMPTE and DVB have developed specific standards for the compression, storage, and transmission of 3DTV content
TVs have are evolving into hybrid TVs, which use both broadcast and broadband networks.
What you'll need to experience 3D TV in your home use of specially designed screen that can
display two different versions of a video image by alternating the video frames at very high speed.

ACTIVE 3DActive 3D uses active 3D glasses, which
rapidly block each eye in time with images shown on the screen. Each eye sees something different, producing a 3D effect. Active 3D TVs provide higher-resolution images with less ghosting, but the glasses are pricey and need batteries.
PASSIVE 3DPassive 3D uses polarized glasses (like you
get in movie theaters) that alter what each eye sees on the screen. The quality level is not quite up to par with active 3D, but passive glasses are much cheaper and don't require batteries.

Viewing in 3D without the help of specs
CONCLUSIONThe proposed new scheme to broadcast 3DTV
over a hybrid network resolves the poor quality issues with 3dtv broadcasting. In order to maintain compatibility with a legacy 2D DTV receiver, the design of this scheme is based on the stereoscopic dual stream method. In addition, the scheme provides a way to overcome the bandwidth limitation of the current 3DTV broadcasting service by using a hybrid network that is widely adopted by current smart TVs.
