Video Functional Block Diagram
Fully loaded X75HD/X75SD frames are the aggregate of discrete
modular solutions as indicated in Figure 1-5. The X75HD/X75SD
contains four independent video frame synchronizers (each with its own
video processing capabilities) and support for multiple processing
functions including up/cross/down conversion, test signal generation,
noise reduction, and aspect ratio conversion. Single or multiple input
video processing is possible, allowing either one input signal to be sent
to all outputs, or independent synchronization, phasing and processing
capabilities for up to four video channels.
