Abstract

A transmitting apparatus is provided. The transmitting apparatus includes: a packet generator generating a packet including a header and a payload from an input stream including a plurality of input packets; and a signal processor signal-processing the packet, wherein the header includes a base header which includes: a first field indicating a packet type of the input packets; wherein when the first field is set to a value indicating that the packet type of the input packets is a TS packet, the base header comprises a second field indicating a number of TS packets included in the payload and a third field set to a first value indicating that the header of the packet does not comprises an additional header or a second value indicating that the header of the packet further comprises the additional header, and wherein the third field is set to the second value when TS header compression to remove at least one header of the TS packets is applied to generate the packet.

Claims

1. A transmitting apparatus comprising at least one processor configured to implement:

a packet generator generating a packet comprising a header and a payload; and

a transmitter transmitting the generated packet,

wherein the header comprises a base header,

wherein the base header comprises a first field, a second field and a third field,

wherein the first field comprises a value indicating that a packet type of an input packet is a transport stream (TS) packet,

wherein the second field comprises a value indicating a number of TS packets included in the payload,

wherein the third field comprises a first value or a second value,

wherein the first value indicates presence of an additional header, and the second value indicates absence of the additional header,

wherein if TS header compression is performed, the third field comprises the first value, and

wherein a header of a TS packet among the TS packets included in the payload is removed by the TS header compression.

2. The transmitting apparatus of claim 1, wherein the first field, the second field, and the third field are implemented as a 3-bit field, a 4-bit field, and a 1-bit field, respectively.
