Distribution method, preferably applied in a streaming system

A network comprising

• at least one Input Data (I) broadcaster (IB), and
• a plurality of peers (P),
• said plurality of peers (P) transforming Input representative data (IRD) from said at least one Input broadcaster (IB) into a first part of a plurality of M unique partial encoded representations (UPR) of Input Data (I),
• at least one of said at least one Input Data (I) broadcaster (IB) transforming Input representative data (IRD) from said at least one Input broadcaster (IB) into a second part of said plurality of M unique partial encoded representations (UPR) of Input Data (I),
• wherein a plurality of code subsets (W1, W2, W3, . . . ) of said M unique partial encoded representations comprises N different unique partial encoded representations (UPR) of said Input Data (I), each of the code subsets (W1, W2, W3, . . . ) representing said Input Data (I) and where N is less than M−1.

A method of streaming data in a streaming system comprising at least one data streaming broadcaster (LSB) and at least two streaming recipients (LSR), the method comprising

• forming at least a part of a peer-to-peer streaming network with said at least two streaming recipients (LSR), and
• generating peer-to-peer streaming of content to other streaming recipients (LSR) of said peer-to-peer streaming network with said at least two streaming recipients (LSR),
• wherein said peer-to-peer streaming of content to other streaming recipients (LSR) is established by means of loss resilient code representations of data from said at least one streaming broadcaster (LSB);
• and
• generating multicast streaming of content to the streaming recipients (LSR) of said peer-to-peer streaming network wherein said multicast streaming of content is established by means of loss resilient code representations of data from said at least one streaming broadcaster (LSB).

A method of distributing input data (I) in a network comprising at least one Input Data (I) broadcaster (TB) and a plurality of peers (P), the method comprising

• transforming, with said plurality of peers (P), Input representative data (IRD) from said at least one Input broadcaster (TB) into a first part of a plurality of M unique partial encoded representations (UPR) of the Input Data (I),
• transforming Input representative data (IRD) from said at least one Input broadcaster (TB) into a second part of said plurality of M unique partial encoded representations (UPR) of Input Data (I),
• wherein a plurality of code subsets (W1, W2, W3, . . . ) of said M unique partial encoded representations comprises N different unique partial encoded representations (UPR) of said Input Data (I), each subset (W1, W2, W3, . . . )
• representing said Input Data (I) and where N is less than M−1.

A data streaming system comprising

• at least one data streaming broadcaster (LSB), and
• at least two streaming recipients (LSR),
• said at least two streaming recipients (LSR) forming at least a part of a peer-to-peer streaming network,
• wherein said at least two streaming recipients (LSR) each comprise a means for generating peer-to-peer streaming of content to other streaming recipients (LSR) of said peer-to-peer streaming network, said peer-to-peer streaming of content to other streaming recipients (LSR) comprises loss resilient code representations of data from said at least one streaming broadcaster (LSB), and
• wherein at least one of said at least one data streaming broadcaster (LSB) comprises a means for generating multicast streaming of content to streaming recipients (LSR) of said peer-to-peer streaming network, said multicast streaming of content to streaming recipients (LSR) comprises loss resilient code representations of data from said at least one streaming broadcaster (LSB), and
• wherein said means for generating peer-to-peer streaming of content to other streaming recipients (LSR) and said means for generating multicast streaming of content to streaming recipients (LSR), substantially provide collectively M unique partial encoded representations (UPR) of Input Data (I), and wherein the number M substantially corresponds to the number of streaming recipients (LSR).

A data streaming system comprising

• at least one data streaming broadcaster (LSB), and
• at least two streaming recipients (LSR),
• said at least two streaming recipients (LSR) forming at least a part of a peer-to-peer streaming network,
• wherein said at least two streaming recipients (LSR) each comprise a means for generating peer-to-peer streaming of content to other streaming recipients (LSR) of said peer-to-peer streaming network, and wherein said peer-to-peer streaming of content to other streaming recipients (LSR) comprises loss resilient code representations of data transmitted by said at least one streaming broadcaster (LSB), and
• wherein at least one of said at least two streaming recipients (LSR) regenerates the encoded data from said streaming broadcaster (LSB) by decoding a number N unique partial encoded representations (UPR) of data and wherein at least one of said N unique partial encoded representations (UPR) is generated by the other streaming recipients (LSR) and at least one other of said N unique partial encoded representations (UPR) is received by multicast delivery.
