Method for requesting a file repair distribution mode
View Patent ↗The present invention concerns a receiver terminal and method at the receiver for requesting a missing symbol from a repair service, the method comprising the steps of receiving from a first server a list of at least one repair server and at least one transmission mode used by the at least one repair server, receiving from a second server a file comprising a plurality of symbols, checking the correct reception of the symbols, and if a missing has been identified, selecting a repair server and a transmissions mode and requesting the repair server to transmit missing symbols using the transmission mode.
1. A method comprising:
receiving from a first server a list of more than one repair server and more than one transmission mode used by each one of said more than one repair server;
receiving from a second server a file comprising a plurality of packets;
checking for the correct reception of the packets; and
if a missing packet has been identified by the checking, selecting a repair server among said list of more than one repair server and a transmission mode among said more than one transmission mode and requesting said selected repair server to transmit said missing packet using said selected transmission mode.
2. Method according to claim 1 , said transmission mode being a point to point mode.
3. Method according to claim 1 , the transmission mode depending on a transmission cost.
4. Method according to claim 3 , said list being comprised in an XML file of an associatedProcedureDescription.
5. Method according to claim 3 , said file being received according to the FLUTE protocol.
6. Method according to claim 1 , said list being comprised in an XML file of an associatedProcedureDecscription.
7. Method according to claim 1 , said transmission mode being a broadcast mode.
8. Method according to claim 1 , said transmission mode depending on a broadcast reception quality.
9. Method according to claim 8 , comprising, prior to the step of requesting, the step of measuring the quality reception on the broadcast reception quality.
10. Method according to claim 8 , said list being comprised in an XML file of an associatedProcedureDescription.
11. Method according to claim 8 , said file being received according to the FLUTE protocol.
12. A receiver comprising:
communicating module that receives data from a broadcast network and for communicating on a bidirectional network;
file reception computing module, on reception of a file from the broadcast network comprising a plurality of packets, that checks correct reception of said packets on said broadcast network;
selecting module that selects, from a list of more than one repair server and more than one transmission mode used by each one of said more than one repair server, a repair server and a transmission mode; and
file reception reporting module that sends a request to said selected repair server on said bidirectional network for requesting said repair server to transmit a missing packet using said selected transmission mode among said more than one transmission mode.
13. Receiver according to claim 12 , said communicating module being adapted to receive a list of more than one repair server and more than one transmission mode used by each one of said more than one repair server.
14. A non-transitory computer-readable storage medium comprising a computer program product with program code instructions for executing on a computer, comprising:
receiving from a first server a list of more than one repair server and more than one transmission mode used by each one of said more than one repair server;
receiving from a second server a file comprising a plurality of packets;
checking the correct reception of the packets; and
if a missing packet has been identified, selecting a repair server among said list of more than one repair server and a transmission mode among said more than one transmission mode and requesting said repair server to transmit missing packets using said transmission mode.
