HYBRID BROADCAST SIGNAL TRANSMISSION AND RECEPTION APPARATUS AND TRANSMISSION AND RECEPTION METHOD

摘要

A hybrid broadcast signal transmission apparatus according to one embodiment of the present invention can comprise: a header repacking unit for receiving an upper (N+1) layer packet composed of a header including a plurality of fields and a payload including broadcast signal data, extracting at least one field included in the header of the received upper (N+1) layer packet, generating an N layer extended header including the extracted at least one field, and generating an (N+1) layer reduced header including fields not having been extracted from the header of the received upper (N+1) layer packet; and a packet generating unit for generating a fixed header of an N layer, generating the N layer packet including the generated fixed header, the N layer extended header, the (N+1) layer reduced header and the payload, and transmitting the generated N layer packet to a lower layer.

1. A hybrid broadcast signal transmission method comprising:
receiving a higher (N+1) layer packet composed of a header including a plurality of fields and a payload including broadcast signal data; extracting at least one field included in the header of the received higher (N+1) layer packet; generating an N layer extended header including the extracted at least one field and generating an (N+1) layer reduced header including the fields which are not extracted from the header of the received higher (N+1) layer packet; generating a fixed header of an N layer; generating an N layer packet including the generated fixed header, the N layer extended header, the (N+1) layer reduced header and the payload; and transmitting the generated N layer packet to a lower layer.
