Apparatus for transmitting broadcasting signal, apparatus for receiving broadcasting signal, and method for transmitting/receiving broadcasting signal through apparatus for transmitting/receiving broadcasting signal
A transmitter and method of processing broadcast data are discussed. In one embodiment, the method includes forward error correction (fec) encoding physical layer pipe (plp) data at a first code rate; fec encoding first signaling data at a second code rate; fec encoding second signaling data at a third code rate; time interleaving the fec-encoded plp data; frequency interleaving the time-interleaved plp data by a pair of consecutive cells; and modulating the frequency-interleaved plp data, the fec-encoded first signaling data, and the fec-encoded second signaling data by an orthogonal frequency division multiplexing (ofdm) method, wherein the first signaling data include fec type information of the second signaling data and wherein the second signaling data include fec type information and the first code rate used by the plp data..

Adapted physical-layer transmission properties based on packet stream
A device may determine adapted physical layer transmission properties based upon characteristics of a packet stream to be transmitted via a communications channel. The physical layer transmission properties may comprise an adapted tone map that is associated with an aggressive physical layer throughput capability for udp traffic, a conservative physical layer throughput capability for tcp traffic, or a dynamically adjusted physical layer throughput rate for mixed traffic.
