Member Function Documentation

int GrAtscFieldSyncDemux::forecast (  VrSampleRange  output, VrSampleRange  inputs[] )  [virtual]

map output range to required input ranges Reimplemented from VrDecimatingSigProc< float, atsc_soft_data_segment >.

virtual const char* GrAtscFieldSyncDemux::name (   )  [inline, virtual]

default name for a module (override with actual name) Reimplemented from VrSigProc.

int GrAtscFieldSyncDemux::work (  VrSampleRange  output, void *  o[], VrSampleRange  inputs[], void *  i[] )  [virtual]

Generate up to output.size output points at o[output#][sample#] using data at the inputptrs[input#][sample#]. Pointers start at corresponding VrSampleIndex in the range params. output.size is a multiple of outputSize. Returns the number of outputs (<= output.size) that it was able to compute with the given input ranges. If this value is < output.size, forecast() will need to be called again. Implements VrSigProc.
