The HDTV YPbPr_VIC I/O
This section provides a comprehensive description of the inputs to and outputs from the YPbPr_VIC. The I/O descriptions are arranged by the source/destination of the signal. The format used is such that the assembly communicated with is used as the primary heading of each group of signals. Those signals are further subdivided into inputs and outputs. Input refers to an Input to the YPbPr_VIC, output refers to an output from the YPbPr_VIC.
