Method and computer product for delivering mail-information and reception device

摘要

A reception device issues a request for delivering mail information containing identification information for a broadcast station broadcasting a program that is currently watched to a mail-information delivery device. The mail-information delivery device acquires identification information for the program that is broadcast by the broadcast station, sorts mail information so that mails containing identification information for the program and identification information for the broadcast station are displayed on a higher rank, and returns a response to the reception device.
