From Stereoscopy to 3D HD Image:A Review of 3D HDTV Diffusion from the Perspective of Technology Adoption
Unformatted Document Text:  16 and nausea (Fry, 2010). A study of visual fatigue for 3D images found that 3D images with a large amount of motion and parallax were not easy to view and caused visual fatigue (Yano, Ide, Mitsuhashi & Thwaites, 2002). One study about health issues related to 3D TV found that 3D TV can cause mental and physical strain in viewers (Johnson, 2010). Seventeen percent of Americans believe that watching 3DTV causes a health risk and fifty five percent are not sure (Fry, 2010). Readiness of Supportive Technological Architecture Readiness of supportive technological architecture is defined as the degree to which the technological structure is capable of supporting the use of an innovation. This concept is used to help review whether the supportive technologies are ready to produce, deliver, present, and watch 3D HD content. Because the first-generation 3D TV is in its early days, watching 3D HDTV needs the supports of other technologies such as the high bandwidth for 3D signal transmission, the active-shutter glasses, and the 3D-ready Blu-ray players. Logically, the bandwidth should be doubled to watch 3D HDTV, because 3D HD signal is essentially two HDTV streams, one for each eye (Ellis, 2010). Consumers need to wear Active-shutter glasses to watch 3D content. Active-shutter glasses are not those throwaway glasses used in 3D movie theater (Taub, 2009). Blu-ray discs have plenty of storage room and can store a separate 1080p signal for each eye (Iozzio, 2010). Not all the Blu-ray players can play 3D Blu-ray discs; only the 3D-ready player can play 3D discs and send the 3D signals to the 3D HDTV. ANALYSIS OF TECHNOLOGICAL AND SOCIAL CHALLENEGES The diffusion of 3D HDTV is facing many challenges. Some challenges are technological issues, while others are the social obstacles.

Readiness of Supportive Technological Architecture
Readiness of supportive technological architecture is defined as the degree to which the

help review whether the supportive technologies are ready to produce, deliver, present, and
watch 3D HD content. Because the first-generation 3D TV is in its early days, watching 3D
HDTV needs the supports of other technologies such as the high bandwidth for 3D signal
transmission, the active-shutter glasses, and the 3D-ready Blu-ray players. Logically, the
bandwidth should be doubled to watch 3D HDTV, because 3D HD signal is essentially two
