Conclusions
- This paper has shown that:
- Introducing 3D TV to a realistic traffic mix on the Internet
will increase downlink loads by a factor of 1.65 and uplink
loads by a factor of 1.45 if 3D Holoscopic video with
horizontal parallax is used for the applications with 3D video.
-
For future work:
- we investigate the effect of increasing video resolutions and
of increasing the sophistication of the 3D TV technologies
such as 3D Holoscopic video with horizontal parallax and
horizontal and vertical parallax are used.
