Hall Research Debuts HDMI-Based Audio Extractor and Inserter
Hall Research just launched the HD-AUD-IO, an HDMI audio manager capable of extracting audio from (de-embedding) and/or inserting audio into (embedding) an HDMI video signal.
The HD-AUD-IO provides one HDMI input and output and with audio embedded on the HDMI it can be extracted and available as both stereo analog or multi-channel digital SPDIF (TOSLINK) — it also provides two audio inputs (analog and digital). Users can select which audio to embed in the HDMI output. It can be the same as the original HDMI audio (pass-thru), SPDIF digitalor 3.5-millimeter L/R analog.
The audio in the HDMI output can be muted using discrete (contact closure) input or RS232 commands. The HD-AUD-IO is capable of generating an HDMI output even with no HDMI input. This can be used to distribute HDMI with only audio (black screen) to TVs.
Advanced EDID management allows users to control the video portion as well as the audio part of the EDID. The EDID presented to the video source can pass from the downstream device or emulated from internal memory. The device can also “learn” the EDID connected to its HDMI output.
The product has a video bandwidth of 18 Gbps and supports resolutions up to 4K @ 60 Hz 4:4:4 with HDR. It supports HDCP 2.2 as well as HDCP 1.4. Here are the specs.
