Paper Abstract

In order to reach the best possible quality for HDTV pictures, there is a need to reconsider the concepts upon which existing standards are based. In particular, the scanning mode for scene analysis, signal processing and display can be progressive instead of interlaced as used in conventional TV standards. This technique improves notably the vertical and the temporal resolution but video bandwidth, bit rate and thus signal processing speeds are twice as big with interlaced mode. However, by using diagonal filtering, it is possible to make a quincunx progressive signal with half the bit rate (1,15 Gbit/s) of the primary digital signal. Then, this signal can be mixed in a HDTV studio or recorded with a digital VTR. This article describes the realization of a new progressive scanning high definition camera working in 1250/50/1 standard. This camera offers the facilities of broadcast cameras and is coupled to the experimental HDP/HDQ mixer developed in the RACE 1080 program by THOMSON-CSF LER allowing the operation ability of a HDTV progressive studio.
