Abstract
A method of receiving broadcast signals according to an embodiment of the present invention may comprise the steps of: receiving broadcast signals; demodulating the received broadcast signals by an orthogonal frequency division multiplex (OFDM) method; parsing at least one signal frame from the demodulated broadcast signals, wherein the at least one signal frame includes service data and signaling data corresponding to at least one physical path; decoding the service data included in the at least one signal frame; and encapsulating a baseband packet including the decoded service data and outputting a container packet.
Claims16
A method of receiving a broadcast signal, the method comprising:
- receiving the broadcast signal including a signal frame;
- demodulating the received broadcast signal by an Orthogonal Frequency Division Multiplex (OFDM) scheme;
- acquiring the signal frame from the demodulated broadcast signal, wherein the signal frame includes service data and signaling data for signaling the service data;
- decoding the service data in the signal frame and outputting a baseband packet including the decoded service data;
- encapsulating the baseband packet into a container packet, wherein the container packet includes a header and a payload, wherein the header includes indication information indicating a start point of the container packet, and wherein the payload includes the baseband packet;
- and
- slicing the container packet into data units having a predefined length and outputting the data units for system decoding.
An apparatus for receiving a broadcast signal, the apparatus comprising:
- a receiver to receive the broadcast signal including a signal frame;
- a demodulator to demodulate the received broadcast signal by an Orthogonal Frequency Division Multiplex (OFDM) scheme;
- a frame parser to acquire the signal frame from the demodulated broadcast signal, wherein the signal frame includes service data and signaling data for signaling the service data;
- a decoder to decode the service data in the signal frame and output a baseband packet including the decoded service data;
- and
- a container encapsulator to encapsulate the baseband packet into a container packet, slice the container packet into data units having a predefined length, and output the data units for system decoding, wherein the container packet includes a header and a payload, wherein the header includes indication information indicating a start point of the container packet, and wherein the payload includes the baseband packet.
