The High-Performance Multimedia Group has developed a High Definition Multimedia Interface (HDMI®) to MIPI®Camera Serial Interface Type 2 (CSI-2) converter module (HDMI2CSI) as a plug in to the NVIDIA Jetson TX1 development kit.
The HDMI2CSI module supports 4K video resolution for next-generation embedded Ultra High Definition video applications. The HDMI2CSI module offers two 4K/2K HDMI video and audio streams to be simultaneously converted in MIPI CSI-2 video and TDM audio format that can be processed by the Jetson TX1 processor.
The Jetson TX1 board is equipped with 3 four-lanes MIPI high-speed camera serial interfaces (CSI-2) which are used by the HDMI2CSI board to input HDMI video. The module utilizes two MIPI CSI-2 ports of the Jetson TX1 board (8 lanes) to input a 4K HDMI video stream. For a second 2K HDMI video stream, the remaining MIPI CSI-2 port is used (4 lanes).
Eight channels of HDMI audio streams per HDMI input are also supported and can be transmitted over TDM or I2S.
4K capable drivers for the HDMI2CSI are available as open source.
