From Stereoscopy to 3D HD Image:A Review of 3D HDTV Diffusion from the Perspective of Technology Adoption
Unformatted Document Text:  2 1977). The two slightly different images are called stereographs. Stereographs refer to the pair of images which have slightly difference in terms of viewing angles and create 3D effect when viewed through a stereoscope, a device used to view stereographs (Darrah, 1977). Since the stereographs were first introduced in 1840s, the technique of stereoscopy has been applied and adapted to many fields such as photography, geology, medical training, movie industry, and other media. 3D technology has been applied to the entertainment media, and a successful application is in theatre. The very first 3D films were produced in 1920s (Pinson, 2010). 3D peaked in theaters in 1953, but disappeared because of the poor technology and bad content (Sasaki, 2010). As the digital technology develops, production and postproduction improve, and 3D glasses evolve, digital 3D has recently been a huge success in the theater (Sasaki, 2010). The success of digital 3D in cinemas accelerates the production of more 3D content, and the appearance of more 3D content in return arouses the interest in 3D throughout the entire digital entertainment value chain (Sasaki, 2010). A specific application is to bring 3D HDTV to people’s homes. 3D HDTV represents the technological convergence between digital 3D technology and HD technology in the TV manufacturing and media industry. As a new entertainment media technology, 3D HDTV may have the chance to be successful. On one hand, digital processing can make it easier to produce, align, and deliver 3D (Wood, 2010); on the other hand, high definition TV (HDTV), rather than standard definition TV (SDTV), can allow higher quality 3D than previously possible (Wood, 2010). Unlike SDTV (standard-definition television) which offers low resolution, 4:3 aspect ratio, and two-channel stereo audio, HDTV can offer higher resolution, 16:9 aspect ratio, and six-channel audio sound.
