Abstract

A data transmitting apparatus is provided. The data transmitting apparatus includes a packet generator configured to generate a packet including a plurality of sub packets and a transmitter configured to transmit the generated packet to a data receiving apparatus. Each of the plurality of sub packets includes audio data corresponding to content among a plurality of contents.

Claims

1. A data transmitting apparatus, comprising:

a packet generator configured to generate a packet including a plurality of sub packets; and

a transmitter configured to transmit the generated packet to a data receiving apparatus,

wherein the generated packet includes a header which includes one of a stream present bit indicating whether or not each of the plurality of sub packets includes audio data and a stream flat bit indicating whether or not the audio data is available data.

2. The data transmitting apparatus as claimed in claim 1, wherein the header further includes a segment indicator field indicating an order of packets including the generated packet.

3. The data transmitting apparatus as claimed in claim 1, wherein the header further includes a B bit indicating whether or not the audio data includes a first frame complying with international electrotechnical commission (IEC) 60958.

4. The data transmitting apparatus as claimed in claim 1, wherein the audio data includes audio signals of two channels or more.

5. The data transmitting apparatus as claimed in claim 1, wherein the audio data complies with an international electrotechnical commission (IEC) 60958 format.

6. A data receiving apparatus, comprising:

a receiver configured to receive a packet including a plurality of sub packets; and

a packet parsing unit configured to perform parsing on the received packet,

wherein the received packet includes a header which includes one of a stream present bit indicating whether or not each of the plurality of sub packets includes audio data and a stream flat bit indicating whether or not the audio data is available data.

7. The data receiving apparatus as claimed in claim 6,

wherein the header further includes a segment indicator field indicating an order of packets including the received packet.

8. The data receiving apparatus as claimed in claim 6, wherein the audio data includes audio signals of two channels or more.

9. The data receiving apparatus as claimed in claim 6, wherein the audio data complies with an international electrotechnical commission (IEC) 60958 format.

10. The data receiving apparatus as claimed in claim 6, wherein the header includes a B bit indicating whether or not the audio data includes a first frame complying with international electrotechnical commission (IEC) 60958.

11. A data transreceiving system, comprising:

a data transmitting apparatus configured to generate a packet including a plurality of sub packets and transmit the generated packet; and

a data receiving apparatus configured to receive the transmitted packet and perform parsing on the received packet,

wherein the generated packet includes a header which includes one of a stream present bit indicating whether or not each of the plurality of sub packets includes audio data and a stream flat bit indicating whether or not the audio data is available data.
