Detailed Description

FECFRAME packet.

Definition at line 35 of file fec.h.

Constructor & Destructor Documentation

◆ FEC()

roc::packet::FEC::FEC ( )

Construct zero FEC packet.

Member Function Documentation

◆ compare()

int roc::packet::FEC::compare ( const FEC & ) const

Determine packet order.

Member Data Documentation

◆ block_length

size_t roc::packet::FEC::block_length

Number of source + repair packets in block to which this packet belongs ("blen").

Remarks: Different blocks can have different number of packets. Always larger than source_block_length. This field is not supported on all FEC schemes.

Definition at line 66 of file fec.h.

◆ encoding_symbol_id

size_t roc::packet::FEC::encoding_symbol_id

The index number of packet in a block ("esi").

Remarks: Source packets are numbered in range [0; k). Repair packets are numbered in range [k; k + n), where k is a number of source packets per block (source_block_length) n is a number of repair packets per block.

Definition at line 47 of file fec.h.

◆ fec_scheme

FecScheme roc::packet::FEC::fec_scheme

The FEC scheme to which the packet belongs to.

Remarks: Defines both FEC header or footer format and FEC payalod format.

Definition at line 39 of file fec.h.

◆ payload

core::Slice<uint8_t> roc::packet::FEC::payload

FECFRAME payload.

Remarks: Doesn't include FECFRAME header or footer.

Definition at line 74 of file fec.h.

◆ payload_id

core::Slice<uint8_t> roc::packet::FEC::payload_id

FECFRAME header or footer.

Definition at line 69 of file fec.h.

◆ source_block_length

size_t roc::packet::FEC::source_block_length

Number of source packets in block to which this packet belongs ("sblen").

Remarks: Different blocks can have different number of source packets.

Definition at line 59 of file fec.h.

◆ source_block_number

blknum_t roc::packet::FEC::source_block_number

Number of a source block in a packet stream ("sbn").

Remarks: Source block is formed from the source packets. Blocks are numbered sequentially starting from a random number. Block number can wrap.
