Consumer show launch for IDTV reference design
iKonvergenz has launched its complete integrated digital TV (IDTV) solutions this week at the 2006 International CES in Las Vegas.
The Kentaurus 3 system architecture is based on the Micronas VCT-Pro all-in-one LCD-TV processor and the Micronas truDHD high-definition frame rate convertor (FRC-H).
Kentaurus 3 is available in different models to address digital TV markets (ATSC and DVB-T) as well as HD-ready markets.
"Kentaurus 3 has been optimised so that TV makers can take advantage of the maximum picture experience of the VCT-Pro and FRC-H system".

Development platform has educational aims
The EmbestUniversity is a teaching platform focused on embedded system development.
"The Micronas 100/120Hz motion blur removal and film de-judder technology is market proven and currently used by many well-known brands in the world", says Wladimir Punt, Director of Marketing, TV at Micronas.
"Both VCT-Pro and FRC-H have been developed to operate together in a system platform to eliminate the motion blur and film judder effects, which are especially visible on larger flat-panel HDTVs".
"TV manufacturers adopting the Kentaurus 3 can immediately introduce film dejudder and motion blur removal solutions to their product portfolio for Pal, NTSC, Secam, ATSC and DVB-T markets", says Torsten Frings, Managing Director of iKonvergenz.
"Such a solution is necessary for 32in or larger LCD TVs, as judder and motion blur are very often visible on the bigger TVs".
Almost all films are shot, edited and mastered at 24 frames per second, but they are broadcast and viewed on LCD TV screens at 50 or 60 frames per second.
Simple frame rate conversion from 24 to 30 frame/s is done using "inverse 3-2 pull-down", a process of repeating certain frames.
This results in an irritating start-stop motion, called film judder.
The Kentaurus 3 uses the Micronas high-definition film de-judder technology, which increases the frame rate by generating additional new frames rather than simply repeating frames.
The best method of overcoming the motion blur effect of LCD TVs is to double the image rate (from 50/60 to 100/120 frame/s).
This technique is superior to black field insertion or backlight scanning, low-cost techniques adopted by some vendors.
Kentaurus 3 delivers outstanding sharpness based on the 100/120Hz motion blur removal technique of the FRC-H device.
LCD panels can offer excellent picture quality despite certain limitations.
But getting the best picture from these panels requires the very best upstream electronics.
Using the Micronas VCT-Pro and Micronas FRC-H, consumers can experience the true quality of LCD-TV without motion blur or film judder.
The Kentaurus 3 design is licensable now.
Like all iKonvergenz products, it has been designed for immediate production.
Bills of materials and all other design documentation are provided.
