Transmitting apparatus, receiving apparatus and signal processing method thereof

摘要

A transmitting apparatus includes: a baseband packet generator configured to generate a baseband packet including a header and payload data corresponding to an input stream; a frame generator configured to generate a frame including the baseband packet; a signal processor configured to process the generated frame; and a transmitter configured to transmit the processed frame, wherein the header includes information about whether a number of null packets deleted when generating the baseband packet is more than a predetermined number, information about a number of packets within the baseband packet, and information about a number of the deleted null packets.

1. A transmitting apparatus comprising:
at least one processor configured to implement:
a DNP (Deleted Null Packets) counter to reset a value to zero and increase the value for each deleted null packet preceding a first non-null transport stream (TS) packet among at least one non-null TS packet; anda packet generator to generate a packet comprising a header and a payload; and a transmitter to transmit the packet, wherein the at least one non-null TS packet is included in an input stream, wherein the at least one non-null TS packet is encapsulated into the payload of the packet, and wherein the value of the DNP counter is used to set a DNP field included in the header of the packet.
