Communication system, receiving device, server, and communication method

Abstract

Program information is transmitted and received via a communication line, and a scheduling operation can be performed based on the program information via the communication line. For that purpose, a communication system includes a receiving apparatus, a server, and an information processing apparatus which are configured to transmit data to and receive data from one another via the communication line. The information processing apparatus includes an EPG requester and a display EPG receiver. The server includes an EPG request receiver, an EPG request transmitter, an EPG receiver, an EPG converter, and a display EPG transmitter. The receiving apparatus includes an EPG obtainer, an EPG request acceptor, an EPG extractor, and an EPG transmitter.

1 . A receiving apparatus configured to transmit and receive data via a communication line, the receiving apparatus comprising:
 an EPG (electronic program guide) obtainer configured to obtain program information (an EPG) from a broadcast signal;   an EPG request acceptor configured to receive an EPG request transmission signal transmitted via the communication line from a server connected to the communication line;   an EPG extractor configured to extract, from the program information (the EPG) obtained by the EPG obtainer, the program information (the EPG) according to the EPG request transmission signal as terminal program information;   an EPG transmitter configured to transmit the terminal program information extracted by the EPG extractor to the server via the communication line;   a schedule information acceptor configured to receive schedule information transmitted from the server via the communication line; and   a schedule executer configured to execute operation based on the schedule information received by the schedule information acceptor.   
     
     
         2 . The receiving apparatus according to  claim 1 , further comprising
 a recorded program accumulator for recording the broadcast signal, wherein the schedule executer causes the recorded program accumulator to record the program based on the schedule information received by the schedule information acceptor.   
     
     
         3 . The receiving apparatus according to  claim 2 , further comprising
 a schedule execution transferor configured to transmit a result of execution by the schedule executer to the server via the communication line.
