Abstract: The present invention is a program receiving display device adapted for a digital broadcasting service and an IPTV service, comprising: a first program stream acquisition unit that acquires a first program stream that constitutes a program content, based on a broadcast signal from a station selected according to a channel number from received broadcast waves; a second program stream acquisition unit that requests distribution of a second program stream, which is equivalent to the first program stream, via a communication network to a specific distribution server according to link information associated with the channel number and that acquires the second program stream distributed from the specific distribution server in response to the request; and a main control unit that performs control to select at least one of the first program stream or the second program stream, and to display the program content based on the selected program stream on a screen.

Abstract: An information communication terminal device adapted for an IPTV service that delivers program data from one of a plurality of delivery servers via a communication network includes a channel selection unit, a program data acquisition unit, and a display control unit. The channel selection unit selects a channel number according to channel allocation which defines allocation of channels corresponding to broadcasting regions. The program data acquisition unit requests a specific delivery server to deliver program data according to link information associated with the selected channel number and acquires the program data delivered from the specific delivery server in response to the request. The display control unit performs control such that program content is displayed on a screen based on the received program data. In response to a first operation by a user with respect to the screen, the channel selection unit determines a channel number of a first switching destination according to the channel allocation.

Abstract: An information communication terminal device adapted for an IPTV service, which delivers program data from one of a plurality of delivery servers via a communication network, includes: a program selection unit, a program data acquisition unit, and a display control unit. The program selection unit selects a program according to EPG information in which program scheduling is defined by a plurality of channels and a plurality of delivery time slots along a time axis, the program being selected based on the channels and the delivery time slots. The program data acquisition unit requests delivery of program data of the program to a specific delivery server according to link information and a program identification code, both of which are associated with the selected program, and acquires the program data delivered from the specific delivery server in response to the request. The display control unit performs control such that program content is displayed on a screen based on the received program data.
