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.
Claims12
A transmitting method of a transmitting apparatus, the transmitting method comprising:
- generating a packet comprising a header and a payload;
- generating a frame comprising the generated packet and signaling information;
- processing the generated frame;
- and
- transmitting the processed frame,
- wherein the header comprises a first field and a second field,
- wherein the first field comprises one of a first value or a second value,
- wherein the first value indicates that a length of the second field is a first length, and the second value indicates that the length of the second field is a second length, and
- wherein, if the first field comprises the first value, the second field is represented as a pointer field, and if the first field comprises the second value, the second field is a concatenation of the pointer field and an added pointer field,
- wherein the second field comprises a pointer value,
- wherein the pointer value is an offset from a beginning of the payload to a first start position of at least one input packet that begins in the payload,
- wherein if the first field comprises the second value, the header comprises a third field including one of a third value, a fourth value and a fifth value,
- wherein the third value indicates absence of a fourth field and a fifth field in the packet,
- wherein the fourth value indicates presence of the fourth field of which a length is 1 byte,
- wherein the fifth value indicates presence of the fourth field of which the length is 2 bytes,
- wherein the fourth field comprises length information indicating a length of the fifth field, and
- wherein if the third field comprises the fifth value, the fourth field comprises least significant bits and most significant bits.
A receiving method of a receiving apparatus, the receiving method comprising:
- receiving a frame comprising a packet and signaling information, the packet comprising a header and a payload;
- and
- processing the packet based on the signaling information,
- wherein the header comprises a first field and a second field,
- wherein the first field comprises one of a first value or a second value,
- wherein the first value indicates that a length of the second field is a first length, and the second value indicates that the length of the second field is a second length,
- wherein, if the first field comprises the first value, the second field is represented as a pointer field, and if the first field comprises the second value, the second field is a concatenation of the pointer field and an added pointer field,
- wherein the second field comprises a pointer value,
- wherein the pointer value is an offset from a beginning of the payload to a first start position of at least one input packet that begins in the payload,
- wherein if the first field comprises the second value, the header comprises a third field including one of a third value, a fourth value and a fifth value,
- wherein the third value indicates absence of a fourth field and a fifth field in the packet,
- wherein the fourth value indicates presence of the fourth field of which a length is 1 byte,
- wherein the fifth value indicates presence of the fourth field of which the length is 2 bytes,
- wherein the fourth field comprises length information indicating a length of the fifth field, and
- wherein if the third field comprises the fifth value, the fourth field comprises least significant bits and most significant bits.
