Further, by using the utilization calculated by the calculation unit 54 as it is, the classification may be stepless.

FIG. 9 is a diagram showing an example of five categories. As shown in FIG. 9, the classification unit 55 classifies the HDMI device 4 into the category of "0" when the HDMI device 4 is not used (the HDMI device 4 whose usage degree is "0").

Further, if the calculated lift value is less than 0.5, the classifying unit 55 classifies the HDMI device 4 into the category “1”. The HDMI device 4 is classified into category "2". Further, if the calculated lift value is 1.0 or more and less than 2.0, the classification unit 55 classifies the HDMI device 4 into the category “3”. The HDMI device 4 is classified into category "4".

Then, as shown in FIG. 10, the classification unit 55 associates the type of each HDMI device 4 connected to each television receiver 1 with the category of each HDMI device 4, and assigns this to each television receiver. The information is stored in the storage unit such as the HDD 44 as "information indicating usage tendency" of the machine 1.

FIG. 10 shows an example in which OTT, game machine, PC, recorder, player, and HDMI device 4 of each type of "other/unknown" are connected to each television receiver (device 1 to device n). ing. In FIG. 10, in the case of the first television receiver (device 1), the OTT, player, and "Other/Unknown" types of HDMI devices 4 are not used, respectively, so that "0" is displayed. It is classified into categories, and an example is shown in which the game machine type HDMI device 4 is classified into category "3", which indicates that the degree of use is high.

In addition, in FIG. 10, in the case of the first television receiver (device 1), the PC type HDMI device 4 and the recorder type HDMI device 4 have a category of "1" indicating that the degree of utilization is low. It shows an example classified into

Similarly, in this FIG. 10, in the case of the n-th television receiver (device n (n is a natural number of 4 or more)), each type of HDMI device 4 of OTT, game machine, and PC is not used. This shows an example classified into the category of "0". In addition, in FIG. 10, in the case of the n-th television receiver (device n (n is a natural number of 4 or more)), the recorder type HDMI device 4 has a moderate degree of usage, so "2" shows an example classified into the category of In addition, in FIG. 10, in the case of the n-th television receiver (device n (n is a natural number of 4 or more)), the HDMI device 4 of the player type has a high degree of usage, so "3" shows an example classified into the category of In addition, in FIG. 10, in the case of the n-th television receiver (device n (n is a natural number of 4 or more)), the HDMI device 4 of the type "Other/Unknown" has a low degree of use, so "1 ” shows an example classified into the category.

The data collection device 2 provides information indicating the type and classified category of each HDMI device connected to each television receiver 1 as information indicating usage trends of each television receiver 1 .

Such information indicating usage trends for each television receiver 1 is provided to companies, broadcasting stations, and the like. Since the above-mentioned information indicating usage trends indicates the preferences of each television receiver 1, a company or the like to which the information indicating usage trends is provided can recommend content corresponding to the preferences indicated by the information indicating usage trends. can be used for In addition, on the broadcasting station side, the viewing information of the television receiver 1 is taken into consideration, and during the time period when the viewer of the television receiver 1 is viewing the broadcast program, the preference indicated by the information indicating the usage tendency is determined.

Calculate degrees. Also, each HDMI device 4 is classified into a category corresponding to each degree of use. Information indicating the type of each HDMI device connected to each television receiver 1 and the classified category is provided as information indicating the usage tendency of each television receiver 1 .

The combination of HDMI devices used has a wide variety of device variations, and the combination of HDMI devices has individuality, so it may be possible to identify an individual from the combination of HDMI devices. For this reason, if comprehensive viewing data is externally provided for each HDMI device, there is a concern that the viewing data may be identified by the recipient.

For example, when a user who is using HDMI devices A, B, and C connected to a television receiver introduces the HDMI device he/she is using on SNS (Social Networking Service), etc., this SNS It may be possible to identify an individual through the introduction of HDMI equipment. Also, even when only one HDMI device is connected to the television receiver, if the connected HDMI device is a unique HDMI device, it may be possible to identify an individual.

However, in the case of the data collection system of the first embodiment, the HDMI devices 4 are classified by type, the usage (usage time) of each television receiver 1 is calculated for each type, and corresponding to each usage Each HDMI device 4 is classified into a category to be used. Then, information indicating the type of each HDMI device connected to each television receiver 1 and the classified category is provided as “information indicating usage tendency” of each television receiver 1 .

Therefore, it is possible to make it difficult to identify the HDMI device 4 itself, thereby preventing the inconvenience of identifying an individual based on the combination of the HDMI devices 4 . In other words, the data collection system of the first embodiment can easily create and provide highly useful indexes in a safe manner without fear of leakage of personal information.

(Modification)
The classification unit 55 classifies each HDMI device 4 into a predetermined category based on the degree of use corresponding to the usage time information when each HDMI device 4 uses the television receiver 1 . However, each HDMI device 4 is determined based on the degree of usage corresponding to the usage time information and the image quality mode set in the television receiver when the HDMI device 4 is using the television receiver. You may classify into a predetermined category.

Therefore, it is possible to provide advertisements that more closely match the tastes of the user. For example, advertisement distribution includes notification of functions, recommendation of contents to users who frequently use OTT, and the like.

(Details of selection operation of advertisement data considering image quality mode information)
Here, the television receiver 1 normally performs predetermined signal processing on an image signal and displays the image signal in order to obtain clear image quality. However, in the case of a game such as an action game that requires an instant response, if the above-described predetermined signal processing is applied to the image signal of the game, the controller button operation timing and the game image are displayed. A time lag occurs between the timing of

For this reason, many television receivers are provided with a display mode dedicated to the game, in which the image signal of the game is displayed without being subjected to predetermined signal processing. If the user is using such a game-specific display mode, it is highly likely that the user likes to play action games. Also, like the first television receiver (device 1) shown in FIG. 10, it is highly possible that users of television receivers who frequently use game machines are users who play action games.

For this reason, the distribution advertisement selection unit 83 selects advertisement data by taking into account the image quality mode information together with the information indicating the usage tendency of the television receiver 1 . This makes it possible to provide advertisements that more closely match the user's tastes. For example, game advertisement distribution includes notification of a new game.
