Abstract

An optimized method for the transmission of multimedia contents between a multimedia content transmitter and a multimedia content receiver in a mobile radio network transmitting a multimedia content description vector from the transmitter to the receiver, calculating a pertinence score of the content from the description vector and as a function of a user profile associated with a user of the receiver, and recovering, at the explicit request of the receiver, a block or blocks of the content not received by the receiver, with a priority depending on the pertinence score associated with the content to which the missing block(s) belong(s).

Claims

1. An optimized method for the transmission of multimedia contents between a multimedia content transmitter and a multimedia content receiver in a mobile radio network, which method includes the following steps:

a step of transmitting a multimedia content description vector from said transmitter to said receiver,

a step of calculating a pertinence score of said content from said description vector and as a function of a user profile associated with a user of said receiver, and

a step of recovering, at the explicit request of said receiver, a block or blocks of said content not received by said receiver, with a priority depending on said pertinence score associated with the content to which said missing block(s) belong(s).

2. The method claimed in claim 1 wherein said recovery step is started according to the value of said score associated with said content, whereby any value greater than or equal to a first threshold referred to as a maximum score leads to immediate recovery on detection of blocks not received, any value less than said maximum score but greater than or equal to a second threshold referred to as an average score causes the recovery of missing block(s) at preprogrammed times when the load on said network is considered to be less, and any value less than said average score but greater than or equal to a third value referred to as a minimum score leads to missing block recovery only when said user requests access to said content.

3. The method claimed in claim 2 wherein said thresholds are updated dynamically as a function of the degree to which a local memory of said receiver is filled so that the sum of the memory sizes needed to store contents received in said cache memory is less than the capacity of said cache memory.

4. The method claimed in claim 1 wherein said recovery step is initiated only after detection of missing blocks subsequent to an expected period of reception of all blocks relating to said content.

5. The method claimed in claim 1 wherein said user profile reflecting interests of said user of said receiver is updated automatically on the basis of access by said user to received contents.
