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.

Claims

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 for receiving 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 for receiving the past program data from the program distribution server;

a remote control reception unit for receiving viewing program information as a remote control signal, the viewing program information containing viewing channel information and/or viewing date-and-time information;

a storage unit for storing at least the program information received; and

a control unit for determining whether program data indicated by the viewing program information is past program data based on the viewing date-and-time information when the remote control reception unit has received the viewing program information, wherein

when determining that the program data indicated by the viewing program information is past program data, the control unit obtains the server identification information contained in the program information stored in the storage unit, and controls the IP data reception unit to connect to the program distribution server indicated by the server identification information and then to receive the program data identified by the viewing channel information and/or the viewing date-and-time information; and

when determining that the program data indicated by the viewing program information is not past program data, the control unit controls the broadcast data reception unit to receive the program data identified by the viewing program information.

2. The television receiver of claim 1, wherein

the server identification information is connection URL information of the program distribution server corresponding to one channel.

3. The television receiver of claim 1, wherein

the server identification information is connection URL information of the program distribution server corresponding to one piece of program data.

4. The television receiver of claim 1, further comprising:

a video recording unit for recording the currently broadcast program data, wherein

when the remote control reception unit has received the viewing program information, the control unit determines whether the program data indicated by the viewing program information is past program data, based on the viewing date-and-time information;

when determining that the program data indicated by the viewing program information is past program data, the control unit determines whether the program data indicated by the viewing program information has been recorded in the video recording unit; and

when determining that the program data indicated by the viewing program information has been recorded in the video recording unit, the control unit controls the recorded program data indicated by the viewing program information to be played back.

5. The television receiver of claim 1, wherein

the control unit controls an electronic program guide corresponding to the viewing date-and-time information received by the remote control reception unit to be displayed;

specific past program data to be selected from the electronic program guide corresponding to the viewing date-and-time information; and

the selected past program data to be received by the IP data reception unit.

6. A method for receiving program data by connecting a television receiver to a program distribution server so as to receive and play back past program data, the method comprising:

a program information storing step for receiving currently broadcast program data, and receiving and storing program information containing server identification information which identifies the program distribution server;

a viewing program information receiving step for receiving viewing program information from a remote control, the viewing program information containing viewing channel information and/or viewing date-and-time information;

a past program determining step for determining, based on the viewing date-and-time information, whether program data indicated by the viewing program information is past program data;

a first program data receiving step for, when the program data indicated by the viewing program information is determined to be past program data, obtaining the server identification information contained in the program information stored in the program information storing step;

connecting to the program distribution server indicated by the server identification information; and

receiving the program data identified by the viewing channel information and/or the viewing date-and-time information; and

a second program data receiving step for, when the program data indicated by the viewing program information is determined not to be past program data, receiving the program data identified by the viewing program information.
