HISTORY Some Video History and the Faroudja Approach Faroudja Laboratories, located in northern Califor- nia’s Silicon Valley, was founded in 1971 by Yves and Isabell Faroudja to develop state-of-the-art of video processing technology. Over the last 20 years, Faroudja Laboratories and its companion R&D center, Faroudja Research, have indeed devel- oped hundreds of advanced electronic processes to improve video enhancement, noise reduction... -
Page 4: Licensees And Awards
Licensees Around the World Faroudja’s inventive approach to improving the qual- ity of video imaging has caught the eye of some of the world’s greatest high technology companies. The following list represents those that have recog- nized the value of Faroudja’s solutions to imaging problems and pay for the opportunity to incorporate this technology in their advanced video products (as of December 1993):... -
Page 5: System Description
SYSTEM DESCRIPTION The Faroudja System LD100 digital scan converter is a precision video instrument used to convert NTSC Composite, Y/C, or 525 line RGB or Component interlaced signals into 525 line progres- sive outputs. Using the LD100 digital scan converter will produce pictures with more details, remove unwanted picture artifacts and, when used with pro- jection systems, produce pictures of exceptional... -

Circuit Description Figure 1 is a block diagram of the LD100 showing signal flow and the location of front panel controls and switches. Composite Video and Y/C (S-VHS) inputs are connected to the units decoder with AGC control and converted to Y, R-Y and B-Y signals. The Y, (Luminance) output from the decoder enters the input switcher while the R-Y and B-Y signal enter the Chroma Enhancement block where the... -
Page 7: Technical Highlights
TECHNICAL HIGHLIGHTS LD100 TECHNICAL HIGHLIGHTS – The LD100 is far more than simply a “line doubler”. It is a truly unique product in the world of high performance video. The LD100 is actually a complex image processor that consists of three distinct components –... - Page 8 on two different mechanisms. Horizontal resolution is a function of bandwidth (frequency response) of the circuitry while vertical resolution is a function of the scanning fre- quency (the number of scan lines in each picture). Given these mechanisms and the average size picture tube being 8-10”, they designed the 525 line broadcast stan- dard so that viewers would not see the scan lines when watching TV.

Page 11: Line Doubler Operating Instructions
LINE DOUBLER OPERATING INSTRUCTIONS For reasons of clarity, this technical overview has been written specifically for the LD100. This description applies as well to the LD100U, with the following exceptions: 1. The LD100U accepts PAL and NTSC signals and switches automatically to the proper standard. 2. - Page 12 Every LD100 is subjected to an intense battery of QC and environmental tests. Then each unit is re-tested and re-calibrated for optimum performance. The component parts used in the LD100 are the finest available, ensuring long term consistent per- formance and reliability. This unique, quality oriented “Faroudja touch” can also be seen in the design of many of the LD100’s controls and features.

TROUBLESHOOTING Problem No power light No picture Colors bleeding Picture not stable Incorrect colors Picture washed out NOTE: To make sure that an input source is not the cause of a problem for a composite source, turn the ter- mination switch off and connect a composite monitor to the composite input Loop input. For a R,G,B input source, turn the three termination switches off and connect a R,G,B monitor to the R,G,B input Loop input. -
Page 14: Appendix A: Remote Control Operation
LD100/LD100U Remote Control Operation Overview Remote control of the LD100 / LD100U Line Doubler is provided by an RS-232 serial interface connector located on the rear panel of the unit. A external controller such as a computer or integrated system controller with an RS-232 interface may be used to control all user accessible functions of the Line Doubler. - Page 15 APPENDIX A Command Line The LD100 is programmed by means of a “Command Line”, which is an ASCII string of up to 255 characters that contains one or more individual instructions to the LD100. The Command Line offers the best compromise between manual opera- tion via a data terminal and automatic control via a controller.

Example: LD100:B###,C###,K###,T###,N###,D###,V,T1,A1,F0 HELP or help This command will return a list of commands used for the LD100 Line Doubler. LD100 Local / Remote Operation The LD100 stores all of it’s settings in a Non-volatile ram and will return to the last known settings when the unit is power up.
