NEWS ZetaCast at DVB World 2007 |

ZetaCast's Ken McCann gave a “state of the union address” on HDTV at DVB 2007 in Dublin, providing one of the Flagship Presentations for the opening day of the conference. Ken reviewed the current status of HDTV deployments in Europe and explored how HDTV may evolve in the future. He went back to fundamentals by explaining how the required video resolution can be calculated by the combination of screen size and viewing distance. He then discussed the possibility of the 1080p/50-60 video format being used for future HDTV systems, in place of the current 720p/50-60 and 1080i/25-30 formats. In the longer term, he suggested that Ultra HDTV formats could provide a truly immersive viewing experience. Ken finished his presentation with a live demonstration of the current state-of-the-art: an Ambarella single chip HDTV encoder compressing 720p/50 content at 8Mbit/s using H.264/AVC. |
