With the advent of the newest Ultra High Definition (“4K”) displays and sources, the latest version of High Definition Copyright Protection (“HDCP”) management was unveiled. For those end-users who have an older, non-HDCP2.2 compliant AVR or AV processor, this presents a major problem.

In order to take full advantage of the video capabilities of a new Full 4K display and to hear all of the high-level HDMI-only Surround Sound formats such as Dolby True HD and DTS-Master, the only solution until now would be to replace the older AVR or Audio/ Video Processor with a new version that is HDCP 2.2 compatible. In smaller systems, that is not a major issue. In larger, audiophile grade installations, replacing a very expensive processor with another very expensive processor is not always an appealing option.

The HDS-12AVR solves this by allowing one HDCP 2.2/ Full 4K source to be sent directly to the new UHD 4K display, while directing any and all available HDMI Audio streams to the existing Surround Decoder. The HDS-12AVR handles all Full 4K formats including 60Hz refresh rate at 4:4:4 color space for a full 18.2Gbps bandwidth. The Audio-Only HDMI output is managed as an HDMI1.4 HDCP 1.4 source with 720p MUTED video, in order to conform with anti-copy rules.

As with all Transformative Engineering products, we have created a solution in a cost effective, innovative and reliable way.

The HDS-12AVR is truly a PLUG & PLAY solution!
