DDRIO is an interface boardset originally consisting of an SIGIO motherboard and a UCCC daughter card.

It was used in conjunction with a Digital Disk Recorder to facilitate SDI input and Color Corrected SDI and Composite output.

Later, an additional board was built containing a better video decoder than the one resident in the DDR.

This was done to improve composite video input performance. The board is called the 7113
