The Hi5-3D is a video multiplexer that combines and synchronizes two HD-SDI inputs into various multiplexed 3D formats for output via HDMI and HD-SDI. The Hi5-3D supports, depending on the video format, "side-by-side", "top-bottom", and "frame-packing" 3D modes. The "side-by-side" and "top-bottom" modes involve compressing, either horizontally or vertically, each input for combining into a single video stream at the same rate of the inputs. The "frame-packing" mode stacks two full resolution inputs into a "tall" frame (at twice the clock and line rates). When selected, "frame-packing" can only be used with 23.98 or 24 input frame rates.
Each input, in addition to 3D processing, can be flipped either horizontally, vertically, or both. This control is provided by 4 switches that can be engaged in any combination. The Hi5-3D supports both DIPswitch control and host control via the Mini-Config application. One of the DIP switches is a "Local/Remote" switch. When in the "Local" mode, the remaining DIP switches support a subset of the user controls. When in the "Remote" mode, AJA's Mini-Config application controls the unit. The last configuration is held in memory on the Hi5-3D for use when disconnected.
The Hi5-3D works with both 2D and 3D inputs. When in the 2D mode, the input is simply passed to the output unmodified. In the 3D mode, the Hi5-3D supports the minimum required 3D modes as defined by the CEA for HDMI 1.4a televisions.
CEA Required 3D modes:
2x SDI 1.5 Gb 720p 50, 59.94, 60 T/B
2x SDI 1.5 Gb 1080p 23.98, 24, 25 T/B, FP
2x SDI 1.5 Gb 1080PsF 23.98, 24 T/B, FP
2x SDI 1.5 Gb 1080i 50, 59.94, 60 S/S
"PsF" inputs are converted to "p" for HDMI output. The SDI output can support S/S and T/B formats only. Future software versions may add other formats.
