context_page_description: DVB 3D-TV is a new standard that partially came out at the end of 2010 which included techniques and procedures to send a three-dimensional video signal through actual DVB transmission standards. Currently there is a commercial requirement text for 3D TV broadcasters and Set-top box manufacturers, but no technical information is in there.
  Nowadays 3D television technology is already in its first steps regarding its standardization, now the major 3D market is in theaters and Blu-ray Disc players with stereoscopic systems, but in the near future it will be extended to diffusion, and later Free viewpoint television will come into our homes, which means the need of new coding and transmission standards.
context_section_description: Regarding how a signal once it's decoded is sent to the display, current stereoscopic  systems use a frame-sequential 3D signal. Left and right frames are sent alternately to the display and by diverse systems like shuttered glasses or polarized glasses are then shown to each eye. This involves that the real frame frequency halves the video frame frequency.
