Testbed operations of three real-time transmission types are described: three-dimensional (+ two-dimensional) High-Definition Multimedia Interface (HDMI) broadcast on Point to Multi-Point connections, two-dimensional HDMI broadcast on Multi-Point to Multi-Point connections, and three-dimensional HDMI full duplex on Point to Point connection. The network design has an optical broadcast topology centered with an “optical hub”. The testbed terminals access the network via an Optical Network Interface Card (ONIC). The optical hub is a passive device that carries out optical signal splitting and coupling. Plural Coarse Wavelength Division Multiplexing (CWDM) wavelengths are transmitted between ONICs via the optical hub. Four wavelengths carry one HDMI signal to provide real-time transmission without compression. One wavelength is dedicated exclusively to carrying the Ethernet frame. This paper first introduces the design and implementation, then explains the issues and further considerations for implementing an HDMI-based three-dimensional broadcast access network.
