Dual Channel 3G/HD Down-Converting Distribution Amplifier with AES Audio Outputs

The 7812DCDA2Q is a high density, dual path down-converter with integrated distribution amplifiers. -HD versions convert common HD/SMPTE ST 292 video signals to common SD/SMPTE ST 259 video signals. -3G versions support 3G/SMPTE ST 424 inputs. Each processing path simultaneously provides re-clocked copies of program inputs and SD program outputs. These modules support frame synchronization and external genlock inputs (card or frame reference) for video timing adjustments. SD program outputs are configurable to be either NTSC/PAL or SMPTE ST 259 compliant. High quality and color frame locked NTSC/PAL outputs are generated using 12 bit composite encoders. High quality and sharp SD outputs are generated using Evertz's proprietary scaling technology. These modules provide standard as well as user defined ARC modes. The 7812DCDA2Q series also supports AFD (SMPTE ST 2016) based steering of ARC modes and can stamp AFD signals on output video. Transitions between ARC modes based on AFD metadata are frame accurate and glitch free. Full broacast quality color correction engines are integrated into the these modules. RGB color legalization and ITU Rec. 709 ?601 color space conversions are also supported. Embedded audio on incoming video signals is de-embedded (16 channels) and re-embedded onto the SD outputs with audio delay matching video delay. Additional audio delay is also available. Audio proc is supported including per channel audio gain, channel swapping and inversion controls. Surround sound (5.1 PCM) to stereo (LtRt or LoRo) down-mixes are supported. With -AA variants, 4x analog audio outputs are available for each processing path. With -AES4 variants, two AES (4x mono) digital audio outputs are available for each processing path. The 7812DCDA2Q series transport closed captioning and time code information from input to output with all required data translations and time code recalculations taking place.
