Abstract

A multiprotocol encapsulation forward error correction (MPE-FEC) frame comprising datagrams and FEC data is shown wherein an MPE encapsulator places datagrams in MPE sections and FEC data in MPE-FEC sections. A time slicing block forms a sequence of bursts and dividing the MPE-FEC frame between bursts, such that MPE sections are sent in at least two bursts. The time slicing block adds a burst number parameter to headers of the MPE and MPE-FEC sections to enable a terminal to determine whether to expect further bursts carrying data from the MPE-FEC frame.

Claims

1. A method comprising:

providing a first data frame, the data frame comprising a first set of data and a corresponding first set of forward error correction data;

forming a sequence of transmissions for transmission in a digital broadcasting network; and

dividing the first data frame between said transmissions, the first set of data being divided between at least two transmissions.

2. A method according to claim 1, wherein at least one transmission does not include forward error correction data.

3. A method according to claim 1, further comprising:

providing a second data frame, the second data frame comprising a second set of data and a corresponding second set of forward error correction data; and

dividing the second data and the second set of forward error correction data in the second data frame between the plurality of transmissions.

4. A method according to claim 3, comprising:

dividing the first data frame into a first set of data frame blocks;

dividing the second data frame into a second set of data frame blocks;

interleaving the first and second sets of data frame blocks; and

sequentially placing the interleaved data frame blocks into the plurality of transmissions.

5. A method according to claim 1, further comprising:

providing each data frame with a respective label for identifying an origin of the data.

6. A method according to claim 1, further comprising:

providing each data frame with a respective label for locating the data frame in a sequence of data frames.

7. A method according to claim 1, further comprising:

providing each transmission with a respective label for identifying the transmission within the plurality of transmissions.

8. A method according to claim 1, wherein providing the first data frame comprises:

providing a first array comprising first and second portions;

filling at least a part of the first array-portion with the first set of data;

determining the first set of forward error correction data in dependence upon data in the first array-portion; and

placing said first set of forward error correction data in the second array-portion.

9. A method according to claim 1, comprising:

encapsulating the first set of data into a first set of multiprotocol encapsulation sections; and

encapsulating said corresponding forward error correction data into a second set of multiprotocol encapsulation sections.

10. A method according to claim 9, wherein forming said plurality of transmissions comprises:

arranging said first and second sets of multiprotocol encapsulation sections temporally-offset groups.

11. A method according to claim 1, wherein said first data frame is a multiprotocol encapsulation-forward error correction frame.

12. A method according claim 1, wherein said digital broadcasting network is a digital video broadcasting network.

13. A computer program comprising a computer readable medium having instructions stored thereon for causing data processing apparatus to perform the method of claim 1.

14. Apparatus, comprising

a processor;

and

memory including computer software, the memory and the computer software configured to, with the processor, cause the apparatus at least to perform the method of claim 1.

15. Apparatus according to claim 14, which is a multiprotocol encapsulation encapsulator.

16. A method according to claim 1 wherein the transmissions are bursts.

17. A method comprising:

providing a first data frame, said first data frame comprising a first set of data and a corresponding first set of forward error correction data;

providing a second data frame, said second data frame comprising a second set of data and a corresponding second set of forward error correction data; and

forming a transmission comprising said first and second data frames for transmission in a digital broadcasting network.

18. A computer program comprising a computer readable medium having instructions stored thereon for causing data processing apparatus to perform the method of claim 17.

19. Apparatus, comprising

a processor;

and

memory including computer software, the memory and the computer software configured to, with the processor, cause the apparatus at least to perform the method of claim 17.

20. A method according to claim 17 wherein the transmission is a burst.

21. A method comprising:

receiving a first transmission from a digital broadcasting network, said transmission including data for a data frame;

placing said data in a data frame;

extracting, from said first transmission, an indication that a second transmission in a sequence of transmissions which includes said first transmission follow;

receiving said second transmission from the digital broadcasting network, said second transmission including further data for said data frame; and

placing said further data in said data frame.

22. A computer program comprising a computer readable medium having instructions stored thereon for causing data processing apparatus to perform the method of claim 21.

23. Apparatus, comprising

a processor;

and

memory including computer software, the memory and the computer software configured to, with the processor, cause the apparatus at least to perform the method of claim 21.

24. A method according to claim 21 wherein the first and second transmissions are respectively first and second bursts.

25. A method comprising:

receiving a transmission from a digital broadcasting network, said transmission including data for a plurality of data frames;

extracting sets of data from said transmission together with indications to which data frame said sets of data belong; and

placing each set of data in a corresponding data frame.

26. A computer program comprising a computer readable medium having instructions stored thereon for causing data processing apparatus to perform the method of claim 25.

27. A computer program according to claim 26 stored on a data carrier.

28. Apparatus, comprising a processor;

and memory including computer software, the memory and the computer software configured to, with the processor, cause the apparatus at least to perform the method of claim 25.

29. A method according to claim 25 wherein the transmission is a burst.
