1. 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, comprising:
a channel selection unit which selects a channel number according to channel allocation which defines allocation of channels corresponding to broadcasting regions;
a program data acquisition unit which 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; and
a display control unit which performs control such that program content is displayed on a screen based on the received program data, wherein
in response to a first operation by a user with respect to the screen, the channel selection unit infers channel numbers of a first switching destination and a second switching destination that are adjacent to the current channel number according to the channel allocation,
the program data acquisition unit acquires first program data according to link information associated with the current channel number, while the program data acquisition unit starts acquiring first switching destination program data according to link information associated with the channel number of the first switching destination and starts acquiring second switching destination program data according to link information associated with the channel number of the second switching destination,
in response to a second operation by the user with respect to the screen following the first operation, the channel selection unit determines one of the inferred channel numbers of the first switching destination and the second first switching destination,
the program data acquisition unit continually acquires, as second program data, the switching destination program data corresponding to the determined one of the channel numbers of the switching destinations, while stopping acquiring the switching destination program data corresponding to one of the channel numbers of the switching destinations that is not determined by the channel selection unit, and
the display control unit performs control such that first program content based on the first program data and second program content based on the second program data are displayed on the screen.
