The LogiCORE IP Video to SDI TX Bridge core converts a native video interface to a native SDI interface. The input is video data with explicit synchronization signals. The output is an SDI virtual interface with one to eight 10-bit data streams and embedded synchronization. This Figure shows the top level bridge architecture.
The core embeds synchronization packets into the SDI data stream. It creates and embeds line numbers into the SDI data stream. It supports SD-SDI, HD-SDI, 3G-SDI Level A, and 3G-SDI Level B, 6G-SDI and 12G-SDI modes. In addition, it supports YCbCr data format at 10-bit and 12-bit per component (bpc). For SD-SDI and 3G-SDI level B modes, it generates the required clock enables. It automatically re-orders sequential video data to parallel data in 3G Level B. It supports interlaced and progressive line standards.
