Starter Kit
To help customer quickly test and commission the HDMI encoding module functions, and save total cost of ownership, DDMALL developes a circuit debugging I/O board, which provides I/O interfaces to the encoding module for AV connection, network connection etc. Users can quickly embed the HDMI codec module into the I/O board to use all functions of the encoding module. One I/O board can load up to 4 encoding modules simultaneously. Moreover, the encoding module + I/O board can be put into use directly as a multi-channel HDMI AV encoder for live streaming.
