Synchronizer. Decoder. Embedder. The single card solution for signal ingest.

This digital synchronizer/embedder accepts either an SDI input or uses Fortel DTV’s proprietary 12-bit adaptive QuadraComb™ comb filter to decode the composite input and generate the SDI output. Integral to the card is an audio embedder, which embeds four channel pairs (two groups) into the SDI output. Audio may be sourced from any of the following: Four balanced analog audio inputs, two AES-3id inputs, embed groups from the SDI input, or from a separate Dolby E input.

QuadraComb decoding 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.

Video path features include proc amp controls, video and chroma AGC, video noise reduction, full-frame test signals, VITS insert, pass or strip input on lines 10-22 (NTSC/525) or 6-22 (PAL/625). On loss of input, hot-switch to a captured frame, test pattern with text overlay, freeze, cut-to-black or timeout.

Audio features include automatic lip-sync correction (follow video synchronizer), manual offset delay of up to five seconds, audio compressor limiter, channel summing or swapping, manual channel phase invert, channel output group assignment, and Dolby E pass-through to the embedder.

Optionally, the FS-516 may be configured to substitute AES outputs for the AES inputs, which provides discrete digital audio outputs synced to the SDI video output. The FS-516 is a modular card for Integrity system frames. Choose either a 1RU standalone frame or a 4RU high-density frame with optional redundant power supply.
