Abstract

Methods and apparatus are provided for outputting broadcast recorded by schedule recording. A schedule recording command message is received from a broadcast output apparatus at a cloud server. Broadcast data corresponding to the schedule recording command message is received. A file format used by the broadcast output apparatus is identified. The broadcast data is transcoded into the file format used by the broadcast output apparatus. The transcoded broadcast data is stored. The transcoded broadcast data is transmitted to the broadcast output apparatus when a broadcast request message is received from the broadcast output apparatus.
