Evertz 7710DCDA-HD HD Down Converter & Distribution Amplifier

The 7710DCDA-HD is a reclocking high definition serial digital video distribution amplifier and a high-quality downconverter for 1.5Gb/s HDTV signals. It can also function as a monitoring distribution amplifier for standard definition 270Mb/s signals. It provides 4 reclocked DA outputs and 3 downconverted SDI or composite analog NTSC/PAL outputs (selectable). It accepts all the popular international SMPTE 292M video formats. When the 7710DCDA-HD downconverts 1080p/23.98sF input video to 525i/59.94 with a 3:2 pulldown, the 3:2 pulldown cadence can be free-running or locked to embedded SMPTE 12M-2 time code.

The Evertz 7710DCDA-HD has color space conversion from ITU rec. 709 to ITU rec. 601, and will provide various downconverted formats such as 16:9 letterbox, 14:9 letterbox, 13:9 letterbox, 4:3 center crop, and 4:3 anamorphic squeeze. It supports Wide Screen Signaling (WSS) on the output to handle various aspect ratios of program material.

Full 10-bit processing is provided throughout the signal path to achieve excellent downconversion quality. The module allows for selectable horizontal and vertical filters to control picture sharpness. It also de-embeds two groups of audio, and re-embeds the audio on the SDI output in time with the video. All parameters may be controlled by use of the on-screen display menu.

The 7710DCDA-HD has a closed caption monitoring capability that decodes CEA-608 or CEA-708 captions that have been encoded into the VANC data space of an HD video input, or CEA-608 captions from an SD video input.

The 7710DCDA-HD provides card edge LEDs to indicate signal present and audio groups present. The 7710DCDA-HD occupies one card slot and can be housed in a 1RU frame which will hold up to 3 modules, a 3RU frame which will hold up to 15 modules, a 350FR portable frame which will hold up to 7 modules or a standalone enclosure that will hold 1 module.
