The content information extractor 20 extracts information on the propensity of the content included in the channel information in the broadcast service area received by the broadcast receiver 10.

The population binarization unit 30 binarizes the information determined as the entity from the extracted content information. In this case, the information determined as the entity is determined based on the entity information previously stored in the memory unit 40 by the user's request. For example, the propensity of the content that is the basis of the above-mentioned individual information is preferably information based on at least one of user biorhythm, gender, age, date, time, and weather.

For reference, FIG. 2 is a diagram illustrating a binarized entity of content information according to an embodiment of the present invention.

As illustrated in FIG. 2, information of contents included in a plurality of broadcast service areas received by a terminal is expressed as a binary number. In other words, the biorhythm information of the user is 8 bits, the weather is 4 bits, and the time is 3 bits. At this time, the size of the population is determined to an appropriate size in consideration of various conditions such as the length of the individual. If the size is too small, an unsuitable result may be obtained. If the size is too large, it may take several generations to find the optimal channel information. Therefore, the population binarization unit 30 may express information about the length of the object. Binarize by setting the appropriate length.
