In step 604, the telematics terminal 10 transmits the data packet of the multimedia contents according to the data encoding method and the data rate.

It is determined in step 605 whether the data rate of the telematics terminal 10 is less than or equal to a predetermined value. If the data rate is less than the predetermined value, the telematics terminal 10 proceeds to step 606. Otherwise,

In step 606, the telematics terminal 10 interrupts the transmission of the data packet to the service relay apparatus 100.

In step 607, the telematics terminal 10 stores the multimedia contents.

In step 608, when the data rate exceeds a predetermined value, the telematics terminal 10 resumes transmission from the data packet whose transmission is interrupted.

In step 609, the telematics terminal 10 determines whether transmission of the entire data packet of the multimedia contents is completed. The telematics terminal 10 proceeds to step 610 when the transmission of the entire data packet is completed,

In step 610, the telematics terminal 10 notifies the service relay apparatus 100 of the end of transmission of the data packet.
