CONTENT PREFERENCE CALCULATION METHOD AND CONTENT RECEPTION APPARATUS

摘要

A content preference calculation method capable of accurately calculating actual preference of viewers for a broadcast content and the like. As preference (Pr) of viewers for a program, a function of ratio Ru (= Dw/Lu) of the viewing time (Dw) of the program per unit time (Lu) and ratio Rc (= Dw/Lc) of the viewing time (Dw) to the program time length (Lc) is defined. As the ratio (Ru) increases, the preference (Pr) increases and as the ratio (Rc) increases, the preference (Pr) increases. For example, Pr = Ru + Rc = (Dw/Lu)+(Dw/Lc). A preference calculation unit (72) calculates the function value from the program viewing history data. A preference updating unit (73) adds the preference (Pr) with a certain ratio to the preference (Po) recorded in a preference database (79) before updated, and records the preference (Pn) after the addition as an updated preference in the preference database (79).
