An apparatus for synchronizing chroma and luma data includes a first
handshake block for luma data, a second handshake block for chroma data,
and a means for providing a handshake signal to the first block and to
the second block based at least in part on a determination that they are
both ready to transfer data, and further for inhibiting provision of the
handshake signal based at least in part on a determination that at least
one of the first block and the second block is not ready to transfer
data.
