Viewing program identification system, method, and program

A viewing program identification method for shooting a screen showing a television program that is currently on air and being watched by a user with a mobile terminal, acquiring a still image from the shot moving image, and identifying the television program being watched by the user in substantially real time based on feature point data calculated from the still image, the method in which a computer executes:

• receiving television program data that is currently on air on a given number of broadcast stations;
• calculating feature points of a scene image acquired from the received television program data at intervals of N seconds in real time, and saving, in a storage unit, feature point data of a predetermined time period immediately before the current broadcast on a broadcast station basis;
• receiving the feature point data of the still image acquired from the television program being watched by the user, the feature point data having been transmitted from the mobile terminal of the user;
• and
• checking the received feature point data against the saved feature point data and identifying a matching scene image that satisfies a predetermined matching condition to identify the television program currently being watched by the user.

A recording medium configured to store a computer program for causing a computer to shoot a screen showing a television program that is currently on air and being watched by a user with a mobile terminal, acquire a still image from the shot moving image, and identify the television program being watched by the user in substantially real time based on feature point data calculated from the still image, the recording medium being configured to store a viewing program identification program causing the computer to implement the functions of:

• receiving television program data that is currently on air on a given number of broadcast stations;
• calculating feature points of a scene image acquired from the received television program data at intervals of N seconds in real time, and saving, in a storage unit, feature point data of a predetermined time period immediately before the current broadcast on a broadcast station basis;
• receiving the feature point data of the still image acquired from the television program being watched by the user, the feature point data having been transmitted from the mobile terminal of the user;
• and
• checking the received feature point data against the saved feature point data and identifying a matching scene image that satisfies a predetermined matching condition to identify the television program currently being watched by the user.
