Abstract

Provided are a transmitting apparatus, a receiving apparatus and controlling methods thereof. The transmitting apparatus includes: at least one processor configured to implement a packet generator which generates a packet including a header and a payload based on a plurality of input packets; and a signal processor which signal-processes the generated packet, and a transmitter configured to transmit the signal-processed packet. A base field included in the header includes a first field set to a first value representing that the base field is a first length or a second value representing that the base field is a second length.

First claim

What is claimed is:

1 . A transmitting apparatus comprising:
at least one processor configured to implement a packet generator which generates a packet comprising a header and a payload based on a plurality of input packets, and a signal processor which signal-processes the generated packet; and a transmitter configured to transmit the signal-processed packet, wherein a base field included in the header comprises a first field set to a first value representing that the base field is a first length or a second value representing that the base field is a second length, and wherein, when the first field is set to the second value, the base field comprises a second field representing least significant bits (LSB) of the pointer value indicating a first start point among respective start points of the input packets included in the payload and a third field representing most significant bits (MSB) of the pointer value.

2 . The transmitting apparatus of claim 1 , wherein the base field comprises a fourth field representing an extension mode of the header, and the fourth field comprises at least one of information about whether an optional field is present, a length of the optional field, and a structure of an extension field.

3 . The transmitting apparatus of claim 2 , wherein the fourth field is set to one of a third value representing that the optional field and the extension field are not present, a fourth value representing that the optional field is present and a length of the optional field is 1 byte, a fifth value representing that the optional field is present and the length of the optional field is 2 bytes, and a sixth value representing the optional field is present, the length of the optional field is 2 bytes, and the extension field has a structure comprising a plurality of extension payloads.

4 . The transmitting apparatus of claim 3 , wherein when the fourth field is set to the fourth value or the fifth value, the optional field further comprises a fifth field representing a type of extension payload included in the extension field and a sixth field representing a length of the extension field, and
when the fifth field is set to predetermined value, the extension field is completely filled padding.

5 . The transmitting apparatus of claim 3 , wherein when the fourth field is set to the fifth value, the optional field comprises a field representing a type of an extension payload included in the extension field, a field representing an LSB part of a length of the extension field, and a field representing an MSB part of the length of the extension field.

6 . The transmitting apparatus of claim 3 , wherein when the fourth field is set to the sixth value, the optional field comprises a field representing a number of a plurality of extension payloads included in the extension field, a field representing an LSB part of a length of the extension field, and a field representing an MSB part of the length of the extension field.

7 . The transmitting apparatus of claim 6 , wherein the extension field comprises a plurality of fields representing respective types of the plurality of extension payloads and a plurality of fields representing respective lengths of the plurality of extension payloads.

8 . The transmitting apparatus of claim 7 , wherein, when the fourth field is set to one of a fourth value and a fifth value and a length of an extension payload included in the extension field is smaller than a length of the extension field, the extension field comprises the extension payload and padding.

9 . The transmitting apparatus of claim 3 , wherein, when the fourth field is set to a sixth value, the extension field comprises a plurality of extension payloads and padding.

10 . A receiving apparatus comprising:
a receiver configured to receive a stream comprising a packet comprising a header and a payload; and at least one processor configured to implement an information extractor which extracts the header from the packet and extract information included in the header, and a signal processor which signal-processes a plurality of input packets included in the payload based on the extracted information, wherein a base field included in the header comprises a first field set to a first value representing that the base field is a first length or a second value representing that the base field is a second length, and wherein, when the first field is set to the second value, the base field comprises a second field representing least significant bits (LSB) of the pointer value indicating a first start point among respective start points of the input packets included in the payload and a third field representing most significant bits (MSB) of the pointer value.

11 . A controlling method of a transmitting apparatus using at least one processor, the method comprising:
generating a packet comprising a header and a payload based on a plurality of input packets; signal-processing the generated packet; and transmitting the signal-processed packet, wherein a base field included in the header comprises a first field set to a first value representing that the base field is a first length or a second value representing that the base field is a second length, and wherein, when the first field is set to the second value, the base field comprises a second field representing least significant bits (LSB) of the pointer value indicating a first start point among respective start points of the input packets included in the payload and a third field representing most significant bits (MSB) of the pointer value.

12 . The controlling method of the transmitting apparatus of claim 11 , wherein the base field comprises a fourth field representing an extension mode of the header, and the fourth field comprises at least one of information about whether an optional field is present, a length of the optional field, and a structure of an extension field.

13 . The controlling method of the transmitting apparatus of claim 12 , wherein the fourth field is set to one of a third value representing that the optional field and the extension field are not present, a fourth value representing that the optional field is present and a length of the optional field is 1 byte, a fifth value representing that the optional field is present and the length of the optional field is 2 bytes, and a sixth value representing the optional field is present, the length of the optional field is 2 bytes, and the extension field has a structure comprising a plurality of extension payloads.

14 . The controlling method of the transmitting apparatus of claim 13 , wherein
when the fourth field is set to the fourth value or the fifth value, the optional field further comprises a fifth field representing a type of extension payload included in the extension field and a sixth field representing a length of the extension field, and when the fifth field is set to predetermined value, the extension field is completely filled by padding.

15 . The controlling method of the transmitting apparatus of claim 13 , wherein when the fourth field is set to the fifth value, the optional field comprises a field representing a type of an extension payload included in the extension field, a field representing an LSB part of a length of the extension field, and a field representing an MSB part of the length of the extension field.

16 . The controlling method of the transmitting apparatus of claim 13 , wherein when the fourth field is set to the sixth value, the optional field comprises a field representing a number of a plurality of extension payloads inclu
