replaces the ATUHD-SYNC. It supports HDR (high dynamic range) video (and metadata) up to 4K/UHD @ 60 Hz with 4:4:4 chroma sampling, and supports HDMI 2.0 data rates up to 18Gbps. It is compatible with all video resolutions, audio formats, and color space formats supported in the HDMI 2.0a specification, as well as HDCP 2.2 compliant. (It’s also compatible with all legacy HDMI 1.2 devices that don’t support the 1.3 clock stretching protocol). The compact solution provides EDID emulation and Hot Plug Detect communication between HDMI sink and source devices. In addition to addressing HDMI signal and device-related issues, the Etude Sync reports HDCP compliance at the source and destination; it can manage EDID communication with the source by delivering EDID from the display or the Etude Sync’s internal memory. Etude Sync is ideal for AV system troubleshooting as well as ensuring reliable, consistent performance. For convenience to installers and technicians in the field, the Etude Sync can be powered via USB by the included power supply, a laptop, or any available USB port nearby. Firmware is field-updatable.
