Program selection device and program selection method

A program selection device which receives a plurality of programs and an EPG, and selects a particular elementary stream, of a plurality of elementary streams received together with one of the plurality of programs which is selected by a user, said device comprising:

• program receiving means for receiving the EPG, the selected program, and the plurality of elementary streams;
• type identification means for identifying types of both the selected program and the plurality of elementary streams;
• rate calculation means for calculating rates at which the user views programs in association with a plurality of program types;
• rate storage means for storing the calculated rates in association with each of the program types;
• and
• ES selection means for specifying a program type based on the calculated rates, and selecting an elementary stream of the plurality of elementary streams received by said program receiving means, the elementary stream corresponding to the specified program type.

A program selection method for selecting a particular elementary stream of a plurality of elementary streams received together with one of the plurality of programs which is selected by a user, after receiving a plurality of programs and an EPG, said method comprising:

• receiving a program selected by the user, the plurality of elementary streams and the EPG;
• identifying a program type of the selected program including the plurality of elementary streams;
• calculating rates at which the user views the programs in association with a plurality of program types;
• storing the rates which are calculated in association with the plurality of program types;
• and
• specifying a program type based on the calculated rates, thereby to select one elementary stream, corresponding to the specified program type, of the plurality of elementary streams received in said receiving.
