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. A device comprising a processor and memory, the processor configured to:

create a 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, said data being generated as Ethernet Jumbo packets, wherein the data transport container is an Internet Protocol packet, wherein the processor is further configured to generate the data transport container further comprising 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 from said different types of data, and, the processor further configured to enable each Internet Protocol physical packet to aggregate a predefined number of Ethernet Jumbo packets, said predefined number is based on the type of data said Ethernet Jumbo packet comprises.

2. The 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. The 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. The 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. The data transport container according to claim 1, wherein among the aggregated jumbo packets corresponding to the first type of data, one jumbo packet comprises a DPX header.

6. Method for transferring a number n of different types of data in a high speed Internet Protocol network from a source device to a destination device, the number n being superior or equal to 2, each type of data from said different types of data being generated as Ethernet Jumbo packets, wherein said method comprises:

aggregating by said source device a predefined number of Ethernet Jumbo packets comprising a unique type of data into an Internet Protocol physical packet of corresponding type, wherein the predefined number is based on the type of data;

combining by said source device together n Internet Protocol physical packet corresponding to each type of data from said different type of data, into an Internet Protocol multiplexing logical block;

transmitting by said source device a stream comprising the Internet Protocol multiplexing logical blocks on the network;

receiving the stream by said destination device; and

filtering by said destination device the received stream in order to recover Ethernet Jumbo packets corresponding to each type of data.

7. The method according to claim 6, 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.

8. The method according to claim 6, 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.

9. The method according to claim 6, 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.
