History

Faroudja Inc. was founded by Yves and Isabel Faroudja in 1971, specializing in video quality improvement, particularly for VCRs, and soon became an acknowledged leader in this field. By 1973, their patents were licensed by various household names in the consumer electronics and broadcast industries.

Faroudja was notable for co-development of the Hi-8 and S-VHS
S-VHS
S-VHS is an improved version of the VHS standard for consumer-level analog recording videocassettes. It was introduced by JVC in Japan in April 1987 with the HR-S7000 VCR and certain overseas markets soon afterwards...

 standards in 1987-1988.

In the 1980s, the company developed technologies for the deinterlacing of NTSC signals, including motion adaptive processing algorithms. In 1989 Faroudja invented and patented film mode detection, also known as inverse 3:2 pulldown detection. Faroudja was the only company in the world that had the ability to detect the original frames of film within the video stream and reconstruct an accurate image, free of motion artifacts containing full vertical resolution.

In 1991 the company created the first professional grade line doubler (480p) (deinterlacer) which incorporated this technology, for use with large CRT projectors used in Hollywood screening rooms and large home theaters. The highly acclaimed LD1 Line Doubler takes standard definition signals and converts them to higher resolutions with improved image quality, free of the usual NTSC artifacts (cross-color and cross luminance). At the same time, Faroudja started manufacturing products based on the same technologies, including adaptive comb filters and video quality improvement products for use with Sony’s U-Matic

U-matic is an analog recording videocassette format first shown by Sony in prototype in October 1969, and introduced to the market in September 1971. It was among the first video formats to contain the videotape inside a cassette, as opposed to the various Reel-to-Reel or open-reel formats of the...

 in 1991.

Improvements in display device technologies drove the requirement for more advanced video processing and scaling. This included the introduction of a new product type called the VP400 Line Quadrupler (480i upconverted to 960p). In 2000 Farodja introduced the industry’s first line doubler for HDTV (1080i upconverted to 1080p). The LD1, the VP400, the DVP5000, DVP3000 and Native Rate Series have made Faroudja the benchmark by which all other video processing is compared. For his lifetime’s work, Yves Faroudja was awarded the prestigious Lifetime Achievement Emmy in Technology and Engineering

, presented in 1998.

The Digital Format Translator (DFT) was introduced in 1998 as a standard definition to high definition converter (480i upconverted to 720p or 1080i) for broadcast TV stations. This processor won Faroudja Labs a third Emmy award in 2001 for the efforts in HDTV processing .

These companies often promoted the DCDi by Faroudja logo, displaying it on products for differentiation and to identify advanced video processing.

Beginning in 2005, a strategic alliance was established with Meridian Audio to manufacture and distribute the Faroudja video processor systems. Today, Meridian markets various video processors exclusively under the Meridian name.

Current technology and branding

Faroudja Video Optimized is a calibration and logo branding program available to TV and Set-Top Box manufacturers who use STMicroelectronics system-on-chip (SoC) solutions with integrated Faroudja video processing algorithms. The program helps properly initialize the video signal processing and optimize the LCD panel to produce an accurate picture. The program includes programming and calibration tools. Calibration steps include adjusing contrast, brightness, gamma levels, color temperature, sharpness, noise reduction filters and backlight levels, as well as Faroudja Adaptive Contrast Control (ACC2) and Active Color Management (ACM3D), to insure extended dynamic range and accuracy in shadow details, as well as natural tone (color quality). The calibrated settings are stored in a video mode called “Faroudja Movie”, optimized for high-end TVs and Blu-Ray HD sources.

 by Faroudja
(directional correlational de-interlacing) technology is an advanced deinterlacing algorithm for upconverting and deinterlacing standard definition NTSC content for display on high-definition flat panel TVs. DCDi by Faroudja corrects several deinterlacing issues, including visible jagged edges in an image, cross-color artifacts and includes Film mode processing.

Faroudja DCDi Cinema was developed around higher performance 10-bit processing with extended picture enhancement controls, an active color management system and 3D Noise Reduction. In addition, Response Time Correction (RTC) technology is included to compensate for the motion blur prevalent in LCD flat panels.

Faroudja DCDi Edge was introduced for low-cost image improvement applications in a memory-less display; it utilizes spatial processing to eliminate the visible jagged edges.

Tools

Quickmatch Tool is a proprietary calibration program used to create the Faroudja Video Optimized settings. It connects to the Faroudja video SoC in the TV and interfaces wth a colorimeter light sensor attached to the TV screen. Specific test patterns are generated which are detected by the colorimeter and processed by the QuickMatch program. The program can correct for variation in the panel to generate more accurate results.

Media Tools is a programming tool that provides direct access to the programming registers of the Faroudja video SoC, allowing for faster development and running of simulations.
