Abstract

The present invention relates to a data transport container for transferring a number n of different types of data in an Internet Protocol network. The number n is superior or equal to 2, and data is generated as Ethernet Jumbo packets, wherein the data transport container is an Internet Protocol packet. The invention also relates to a source device and to a destination device respectively for transferring and receiving such a data transport containers. At least, the invention relates to a method for transferring n different types of data being generated as Gigabit Ethernet RTP-UDP-IP jumbo packets. Both devices are to be used in a method as mentioned above.

Claims

1. Data transport container for transferring a number n of different types of data in a high speed Internet Protocol network, the number n being superior or equal to 2, data being generated as Ethernet Jumbo packets, wherein the data transport container is a Internet Protocol packet, characterized in that it comprises a succession of Internet Protocol multiplexing logical blocks, each logical block comprises a combination of n Internet Protocol physical packets corresponding to each type of data, and each Internet Protocol physical packet aggregates a predefined number of Ethernet Jumbo packets depending on the type of data it comprises.

2. Data transport container according to claim 1, wherein n is equal to 2, data of a first type is a DPX wrapped video content generated by a source and data of a second type is an AIFF audio signal generated by the source, where the AIFF audio signal maintains a time relation with the video content.

3. Data transport container according to claim 1, wherein n is equal to 3, data of a first type is a DPX wrapped video content generated by a source and data of a second type is an AIFF audio signal generated by the source, where the AIFF audio signal maintains a time relation with the video content, data of a third type is an Intercom audio signal presented as an AIFF audio signal without any time relation with the video content.

4. Data transport container according to claim 1, wherein n is equal to 4, data of a first type is a DPX wrapped video content generated by a source and data of a second type is an AIFF audio signal generated by the source, where the AIFF audio signal maintains a time relation with the video content, data of a third type is an Intercom audio signal presented as an AIFF audio signal without any time relation with the video content, data of a fourth type is Metadata.

5. Data transport container according to one of claims 2 to 4, wherein among the aggregated jumbo packets corresponding to the first type of data, one jumbo packet comprises a DPX header.

6. Source device for sending a data transport container according to one of the claims 1 to 5 in a high speed Internet Protocol network, the data transport container comprising a number n of different types of data, the number n being superior or equal to 2, each type of data being generated as Ethernet Jumbo packets, characterized in that it includes:

a. means for aggregating a predefined number of Ethernet Jumbo packets comprising a unique type of data into an Internet Protocol physical packet of corresponding type;

b. means for combining together n Internet Protocol physical packet corresponding to each type of data into an Internet Protocol multiplexing logical block; and

c. means for transmitting a stream comprising the Internet Protocol multiplexing logical blocks on the network.

7. Destination device for receiving a data transport container according to one of the claims 1 to 5, the data transport container comprising a number n of different types of data, the number n being superior or equal to 2, each type of data being generated as Ethernet Jumbo packets, characterized in that it includes:

a. means for receiving the streams; and

b. means for filtering the received streams in order to recover Ethernet Jumbo packets corresponding to each type of data.

8. Method for transferring a number n of different types of data in a high speed Internet Protocol network, the number n being superior or equal to 2, each type of data being generated as Ethernet Jumbo packets, characterized in that it comprises steps of:

a. aggregating a predefined number of Ethernet Jumbo packets comprising a unique type of data into an Internet Protocol physical packet of corresponding type;

b. combining together n Internet Protocol physical packet corresponding to each type of data into an Internet Protocol multiplexing logical block;

c. transmitting a stream comprising the Internet Protocol multiplexing logical blocks on the network;

d. receiving the stream; and

e. filtering the received stream in order to recover Ethernet Jumbo packets corresponding to each type of data.

9. The method according to claim 8, wherein data of a first type is a DPX wrapped video content generated by a source and data of a second type is an AIFF audio signal generated by the source, where the AIFF audio signal maintains a time relation with the video content.

10. The method according to one of claim 8 or 9, wherein data of a third type is an Intercom audio signal presented as an AIFF audio signal without any time relation with the video content.

11. The method according to one of claim 8 to 10, wherein data of a fourth type is Metadata.
