Pair it with the DAS-441A and it¡¯s also an audio embedder. Switch between PAL and NTSC via the user menu.
The SDI synchronizer accepts an SDI input or uses Fortel DTV's proprietary 12-bit adaptive QuadraComb¢â comb filter to decode the composite input and generate the SDI output. This decoder generates a cleaner, more accurate SDI signal by eliminating quantizing errors and unwanted comb artifacts. Dual Band Processing and Dynamic Threshold Modification preserve luminance detail and reduce chroma crawl and false chroma. In analog-to-SDI conversion applications, the DUPLEX feature allows the card to utilize the SDI input and analog outputs as a separate converter— intended for wrap-around applications such as the input and output of a digital island. With duplex off, one selected input (analog or digital) is the source for the two analog and two digital outputs, post synchronization.
Its Perfect-Palette¢â Legalizer fixes gamut errors better by first analyzing ¡°what color it was supposed to be¡± and then correctly adapting each pixel to a legal value without causing a hue shift while minimizing clipping effects. Independent settings for RGB, Luminance and Composite thresholds.
The FS-514 modular card can be combined with other Integrity system frames, cards and control panels for compact installation in both mobile and fixed applications.
