First Claim
1. A television receiver connecting to a program distribution server so as to receive and play back past program data, the television receiver comprising:
- a broadcast data reception unit configured to receive currently broadcast program data and program information, the program information containing server identification information which identifies the program distribution server;
an IP data reception unit configured to receive the past program data from the program distribution server;
a remote control reception unit configured to receive viewing program information as a remote control signal, the viewing program information containing at least one of viewing channel information and viewing date-and-time information and being selected by a viewer independent of an electronic program guide (EPG);
a storage unit for storing configured to receive at least the program information received; and

Abstract
Using a remote control, a viewer specifies the channel and the date and time of a program that he/she wants to watch. A reception method selection unit determines, based on the date and time, whether the program is currently being broadcast or was broadcast in the past, and then selects a reception method. An SI information storage unit stores URL information of program distribution servers having past programs. The URL information is contained in the SDT in SI information transmitted together with a program. When the viewer chooses a past program, an IP data reception unit connects to the corresponding program distribution server based on its URL so as to transmit the date and time thereto, and receives the past program that the viewer wants to watch via IP network.
