Abstract

Data associated with transmitted information over a communication network are transmitted. The data are divided into data groups. An information item representative of the importance of the data of the data group is associated with each data group. A transmission cycle for the data groups is determined. Each data group is inserted into the determined transmission cycle a number of times depending on the importance of the data of the data group.

Claims

1-16. -16. (canceled)

17. Method of transmitting data associated with transmitted information over a communication network, wherein the data are divided into data groups, an information item representative of the importance of the data of the data group being associated with each data group, the method comprising the steps of:

determining a transmission cycle for the data groups,

inserting each data group into the determined transmission cycle, each data group being inserted a number of times depending on the respective importance of the data of the data group.

18. Method according to claim 17, wherein the communication network includes a broadcast network and the information and data are transmitted over the broadcast network.

19. Method according to claim 17, wherein the communication network includes a telecommunication network, the information is transmitted on a transmission channel of the telecommunication network and the data are transmitted on a predetermined channel of the telecommunication network which is different from the channel on which the information is transmitted.

20. Method according to claim 19, further comprising transmitting the inserted data group each time a data group is inserted into the transmission cycle for the data groups.

21. Method according to claim 20, further including spacing the insertions of the data group by a predetermined number of insertions of other data groups into the transmission cycle.

22. Method according to claim 20, wherein in that the data groups are inserted into the transmission cycle in an order which depends on their importance compared to the other data groups.

23. Method according to claim 22, further comprising:

ordering the data groups as a function of their importance,

associating a counter with each data group, the value of each counter being representative of the minimum number of insertions of other data groups before an insertion of the data group with which each counter is associated in the insertion cycle,

determining the data group to be inserted as a function of the order of the data groups, the value of the associated counters and the number of times that at least one data group has been inserted into the transmission cycle.

24. Method according to claim 23, wherein each counter is set to a predetermined value prior to the first insertion of a data group into the transmission cycle, setting the counter associated with the inserted data group to a value equal to the number of insertions of other data groups, spacing apart the insertions of the data group with which the counter is associated, and decrementing the value of each counter associated with the other data groups each time a data group is inserted into the transmission cycle.

25. Method according to claim 24, further including (a) ascertaining whether (i) the value of the counter associated with the current data group is strictly greater than the predetermined value, or (ii) the current data group has been inserted into the transmission cycle a predetermined number of times the next data group of the ordered data groups is considered to be the current data group, and (b) taking the first of the ordered data groups as the current data group.

26. Method according to claim 25, further including determining the moment of insertion of a data group, on the basis of the size of the previously inserted data group or groups and on the bandwidth of the transmission channel.

27. Method according to claim 26, further comprising determining the total number of insertions of data groups to be inserted into the transmission cycle, and once the data groups have been inserted into the transmission cycle a number of times that is equal to the total number of insertions the method comprises the steps of:

waiting a predetermined period of time,

determining a new transmission cycle, and

inserting information groups into the determined new transmission cycle.

28. Method according to claim 27, wherein the predetermined period of time is zero.

29. Method according to claim 27, further comprising analyzing the transmission cycle including the inserted data groups and modifying the bandwidth of at least one of the transmission channel and the information items representative of the importance of the data of at least one data group as a function of the analysis of the transmission cycle.

30. Method according to claim 17, wherein the information is audiovisual information and in the data include information for configuring a decoder of at least one of (a) the audiovisual information, (b) data representative of the content of the transmitted audiovisual information, (c) data for indicating the or each channel of the telecommunication network which comprises the transmitted information and (d) attribute data of the audiovisual information.

31. Method according to claim 17, further including dividing the data into date group and associating with each data group an information item representative of the data group.

33. A processor arrangement for performing the process of claim 17.

34. A data carrier or storage device including a program to program a computer to perform the steps of claim 17.

32. Device for transmitting data associated with transmitted information over a communication network, the data being divided into data groups, and an information item representative of the importance of the data of the data group being associated with each data group, the device comprising:

means for determining a transmission cycle for the data groups, and

means for inserting each data group into the determined transmission cycle and for causing, each data group to be inserted a number of times depending on the respective importance of the data of the data group.
