Starter Kit
To help customer quickly debug and use the funcstions of encoding module, and save total cost of ownership, DDMALL also developed corresponding debugging I/O board, which provides I/O interfaces for module audio and video link, network connection etc. Users can run all of functions of encoding module by embedding the module into the I/O interface on the debugging board. One I/O board can load 4 encoding modules simultaneously. Moreover, encoding module + I/O board can be put into use directly as a multi-channel audio and video encoding device.
