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 (Cable, Terrestrial or Satellital). 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. == Implantation == The implantation of first generation of DVB 3D-TV will be staggered: *Phase 1: the first standard will have forward compatibility with actual HD systems with just some firmware actualization at HD systems set-top boxes and, of course, the need for 3D panels; however signaling or distribution formats should not prevent future expansion to support new 3D encoding formats. This system only works with stereoscopic Frame sequential 3D systems. Requirements for this system, which is called Frame compatible format, are included in the commercial requirements of DVB. Some broadcasters like Sky3D〔(【引用サイトリンク】 title= Sky 3DTV site )〕 or Canal+3D〔(【引用サイトリンク】 title= Canal+3D site )〕 are already using this technology, which is largely thought for PayTV. *Phase 2: the use of new broadcasting requirements for specific 3D streams won't be compatible with actual 3D STB, but it would be service compatible with 2D STB if no specific 3D STB is available by using Scalable Video Coding and Multiview Video Coding techniques, i.e. not having to simulcast 2D and 3D and occupying only one channel by using a unique video stream with a normal 2D base stream and an adjustable 3D depth layer. This system is called service compatible and is designed for Free-to-air group of broadcasters. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DVB 3D-TV」の詳細全文を読む スポンサード リンク
