Broadcast transmission device and operating method thereof, and broadcast reception device and operating method thereof

A method for receiving a broadcast signal in a digital broadcast receiver, the method comprising:

• receiving the broadcast signal carrying a transport packet, wherein the transport packet consists of at least one packet payload and at least one packet header;
• frequency deinterleaving symbols of a signal frame in the broadcast signal based on addresses generated by checking a range of addresses of a deinterleaving sequence that is generated based on a main sequence and a symbol offset,
• wherein the signal frame includes a first symbol for signaling data and a second symbol for service data;
• and
• extracting the at least one packet header,
• wherein a first extension header is included in the at least one packet header, further the first extension header includes timestamp information having a 64-bit format depending on a specific value also included in the first extension header,
• wherein the at least one packet header includes a second extension header when the first extension header is included in the at least one packet header, and
• wherein the second extension header includes first information for sender current time of a broadcast sender and second information for expected residual time.

A method for transmitting a broadcast signal in a digital broadcast transmitter, the method comprising:

• generating a transport packet,
• wherein the transport packet consists of at least one packet payload and at least one packet header,
• wherein a first extension header is included in the at least one packet header, further the first extension header includes timestamp information having a 64-bit format depending on a specific value also included in the first extension header,
• wherein a second extension header is inserted into the at least one packet header when the first extension header is included in the at least one packet header, and
• wherein the second extension header includes first information for sender current time of a broadcast sender and second information for expected residual time;
• and
• transmitting the broadcast signal carrying the transport packet.

A digital broadcast transmitter for transmitting a broadcast signal, the digital broadcast transmitter comprising:

• a processor configured to generate a transport packet,
• wherein the transport packet consists of at least one packet payload and at least one packet header,
• wherein a first extension header is included in the at least one packet header, further the first extension header includes timestamp information having a 64-bit format depending on a specific value also included in the first extension header,
• wherein a second extension header is inserted into the at least one packet header when the first extension header is included in the at least one packet header, and
• wherein the second extension header includes first information for sender current time of a broadcast sender and second information for expected residual time;
• and
• a transmitting antenna configured to transmit the broadcast signal carrying the transport packet.
