Do We Need Video Systems “Beyond HDTV”? [Point of View]

Beyond HDTV is a very appealing notion for people involved in the development of video systems. Thinking outside the box, such a television system could be constructed in a completely original manner, but to design an actual working system in the present, the system would relate to current HDTV and follow in the footsteps of television systems that have come before it. This being the case, resolution, frame rate, scanning method, colorimetry, aspect ratio, and other parameters must be targeted for study. As for advanced 3DTV systems, a variety of systems can be considered, and by progressing in the order of multiview, integral, and holographic 3-D systems, we can envision the configuration of a "dream system" far removed from the traditional concept of 2-D systems. Depth information of the 3-D video systems, in general, is converted to 2-D images when recorded and transmitted. Therefore, a drastic improvement of resolution enables the system to carry enough depth information.
