Detailed Description

pad mpeg ts packets from 188 byte char to to 256 byte atsc_mpeg_packet

input: unsigned char; output: atsc_mpeg_packet

Member Function Documentation

void atsc_pad::forecast ( int  noutput_items, gr_vector_int &  ninput_items_required  )

virtual

Estimate input requirements given output request.

Parameters

noutput_items	number of output items to produce
ninput_items_required	number 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_decimator.

void atsc_pad::reset ( )

inline

int atsc_pad::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.
