We have been researching and developing a computer language TVML (TV program Making Language) which enables users to make TV programs based on real-time CG (Computer Graphics), only by describing TV program script on their PC. TVML Player, which is a program application on Windows PC, generates TV programs using real-time CG and voice synthesis etc. by interpreting the script written in TVML. This time, we have developed an ad-lib type TVML system, which enables users to control CG character's action on TVML Player easily by simple action description, by using external control function of TVML Player. And we introduce an application of this system for actual program production.

We have developed a prototype single-chip color HDTV camera for broadcasting. This camera uses a 1.25-inch 8.9-M-pixel CMOS image sensor for obtaining enough resolution characteristics and signal-to-noise ratio (SNR) in a singlechip color system. The camera has an HD-SDI output and a body weight of only 1.4 kg (3.1 lb). The measured resolution was more than 35% on a modulation transfer function (MTF) (45% on a square wave response) at 800 TV-lines. The sensitivity was an f-stop of 11 at 2000 lux with a dynamic range of 400%, and the SNR was 60 dB. These characteristics were as high as those with conventional 2.2-M-pixel 3-CCD HDTV cameras. The measured color difference (delta-E) between this camera and a 3CCD camera on a CIELAB color space was about 9.3. Our simulation showed that the delta-E was about 1.8 with a linear matrix color correction.
