The Apantac OG-SDI-HDTV-SET-1 is an openGear Bundle with both the OG-SDI-HDTV-MB and the OG-SDI-HDTV-RM. The main board can auto-detect 3G SDI (1080p - SMPTE-425M level A) HD-SDI (720p, 1080i) or SD-SDI (525,625) to an HDMI output. The rear module auto-detects 3G SDI (1080p - SMPTE-425M level A) HD-SDI (720p, 1080i) or SD-SDI (525,625). The rotary switch allows selecting one of the 8 embedded AES pairs and sends it to the analog stereo audio output.
