input: atsc_data_segment; output: atsc_data_segment.


Member Function Documentation

void atsc_field_sync_mux::forecast ( int  noutput_items,
gr_vector_int ninput_items_required 
) [virtual]

Estimate input requirements given output request.

Parameters:
noutput_itemsnumber of output items to produce
ninput_items_requirednumber of input items required on each input stream

Given a request to product noutput_items, estimate the number of data items required on each input stream. The estimate doesn't have to be exact, but should be close.

Reimplemented from gr_sync_block.

void atsc_field_sync_mux::reset ( ) [inline]
int atsc_field_sync_mux::work ( int  noutput_items,
gr_vector_const_void_star input_items,
gr_vector_void_star output_items 
) [virtual]

just like gr_block::general_work, only this arranges to call consume_each for you

The user must override work to define the signal processing code

Implements gr_sync_block.
