HEC - HDMI over Ethernet Channel

HEC라는 기능으로 HDMI 1.4 이상부터는 Fast Ethernet을 HDMI를 통해서 전송할수 있다.
머.. 1.4가 2009년에 제정되었지만 솔찍히 이런 장비가 있는지도 몰랐고
그런 기능이 있는지도 몰랐는데 케이블을 이번에 사고 나서 설명을 보다보니 헐.. 깜놀!

 

Version 1.4

HDMI 1.4 was released on May 28, 2009, and the first HDMI 1.4 products were available in the second half of 2009.[106][137] HDMI 1.4 increases the maximum resolution to 4K × 2K, i.e. 3840 × 2160p (Quad HD) at 24 Hz/25 Hz/30 Hz or 4096 × 2160p at 24 Hz (which is a resolution used with digital theaters); an HDMI Ethernet Channel (HEC), which allows for a 100 Mbit/s Ethernet connection between the two HDMI connected devices so they can share an Internet connection;[56] and introduces an Audio Return Channel (ARC),[55] 3D Over HDMI, a new Micro HDMI Connector, expanded support for color spaces, with the addition of sYCC601, Adobe RGB and Adobe YCC601; and an Automotive Connection System.[106][138][139][140][141] HDMI 1.4 supports severalstereoscopic 3D formats including field alternative (interlaced), frame packing (a full resolution top-bottom format), line alternative full, side-by-side half, side-by-side full, 2D + depth, and 2D + depth + graphics + graphics depth (WOWvx),[103][142][143] with additional top/bottom formats added in version 1.4a. HDMI 1.4 requires that 3D displays support the frame packing 3D format at either 720p50 and 1080p24 or 720p60 and 1080p24.[143] High Speed HDMI 1.3 cables can support all HDMI 1.4 features except for the HDMI Ethernet Channel.[103][142][143]
