Member Function Documentation

decode_frame()

virtual char * Coding_session::decode_frame ( char * received_data, int buf_size, int * frame_size, std::map< int, int > valid_data )

pure virtual

Method decode should recover original source data

Parameters

received_data	Received data (source and parity)
buf_size	Size of the received buffer
frame_size	Output parameter for storing size of the decoded frame
valid_data	Map storing pairs <offset, number of bytes> of received data

Returns

Recovered source data

Implemented in LDGM_session, LDGM_session_cpu, and LDGM_session_gpu.

encode_frame()

virtual char * Coding_session::encode_frame ( char * source_data, int frame_size, int * buf_size )

pure virtual

Method encode should compute parity data for the given source data and add suitable FEC parity header.

Parameters

source_data	Data to encode
frame_size	Size of the frame being encoded
buf_size	Output parameter for storing total size of the returned buffer

Returns

Computed parity data with appropriate FEC parity header

Implemented in LDGM_session.
