Information communication terminal device and method for controlling display in said device

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. The program data acquisition unit acquires first program data delivered from a specific delivery server according to link information associated with the current channel number, while, in response to a second operation, subsequent to the first operation, with respect to the screen, the program data acquisition unit starts acquiring second program data delivered from a specific delivery server according to link information associated with the determined channel number of the first switching destination. 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.
