Abstract:
A broadcasting reception apparatus receiving broadcast signals transmitted with a data broadcasting method of transmitting program signals of two or more kinds of broadcasting formats, and decoding software program, for decoding the program signals, via a plurality of channels, said apparatus comprising:a library buffer for holding decoding software programs for decoding program signals; a program obtaining unit for obtaining decoding software programs for decoding program signals from the broadcast signals, and storing the decoding software programs in said library buffer; a checker for deciding whether said library buffer holds decoding software programs for decoding program signals being transmitted via each of said plurality of channels, or not, and for a channel for which said library buffer does not hold decoding software programs, predicting time which it takes to obtain the decoding software program by said program obtaining unit; and a channel display unit for presenting a display based on a result of the decision by said checker, the display making it possible to recognize whether said library buffer holds a decoding software program for decoding a program signal being transmitted via each channel, or not, and whether it takes a long or short time to obtain a decoding software program by said program obtaining unit, for a channel for which said library buffer does not hold the decoding software program.
