N 15) The total viewing time of all channels watched by the user in each unit time period when the user watches the TV every day, and in this embodiment, the unit time period refers to the time of two adjacent hour points. The interval, that is, 1 hour, and the data collection module 1 determines that the channel having the longest total viewing time in the unit time period is an effective channel. Then, as shown in step S22 of FIG. 2, the data collection module 1 sorts the collected effective channels to generate an effective channel information table for the user to watch the TV channel every day for N consecutive days, and transmits the data to the data. The storage module 2 stores, wherein the effective channel information table records the effective channels of each unit time period in a continuous N days.

Specifically, assume that during the unit time period from January 18 to 19, the user has watched channel A, channel B, and channel C, and the total viewing time of channel A, channel B, and channel C is 25.2. Minutes, 20.3 minutes, 14.5 minutes. Since the total viewing time of channel A is the longest, the data analysis module 3 determines that the channel A is the effective channel of the unit time period from 18:00 to 19:00 in January 1, according to the above method. You can find the effective channels of other time periods in January 1st, which will generate the effective channel information of the user on January 1st. Therefore, the data analysis module 3 can generate other dates according to the above method (for example, 1). The effective channel information of each unit time period of the month 2~13), and the effective channel information of January 1st to 13th is integrated into a valid channel information table and stored in the data storage module 2.

Next, as shown in step S23 of FIG. 2, the data analysis module 3 reads the valid channel information table stored in the data storage module 2, and performs weight calculation according to the effective channel information table to generate an ideal channel information table and transmit the data to the data. The storage module 2 stores, wherein the ideal channel information table records an ideal channel in each unit time period of the day, and the ideal channel is an effective channel having the largest weight value in the unit time period.

In this embodiment, when 11 N At 1500, the data analysis module 3 generates the ideal channel information table according to a weight calculation formula, and the weight calculation formula is S=a×M+b×K+c×L, where S is a unit time in a day. a weight value of a valid channel being viewed in the segment, and the consecutive N days are divided into a first phase including the first day to the fifth day, and a second phase and the sixth day from the sixth day to the tenth day a third phase from 11 days to the Nth day, and L is the total number of days in which the effective channel is viewed during the first time period, and c is the first phase within the unit time period, being viewed a weight value of the effective channel; K is the total number of days in the second period in which the effective channel is viewed, and b is a valid channel in the second phase that is viewed during the unit time period. The weight value; M is the total number of days in the third period in which the effective channel is viewed in the unit period, and a is a weight value of the effective channel that is viewed in the unit period in the third period; >b>c, and a+b+c=1.

The data analysis module 3 calculates a weight value of all effective channels in each unit time period in a day according to the weight calculation formula, and sets the effective channel having the largest weight value in each unit time period as each unit time period. The ideal channel, and when there are more than two valid channels with the same weight value and the largest effective channel in the unit time period, the day of the effective channel information table closest to the smart TV boot date has the maximum weight in the unit time period. The valid channel of the value is the ideal channel for the unit time period.

According to this, when the smart TV 100 is turned on, the boot channel selection module 4 of the smart TV 100 reads the ideal channel information table from the data storage module 2, and according to the unit time period corresponding to the time when the power is turned on. The ideal channel corresponding to the unit time period is automatically selected in the ideal channel information table, and the television program in the ideal channel is transmitted to a display module 5 (including a display) of the smart TV 100 for broadcast.

From January 6th to January 10th, it is the second stage, and January 11th to January 13th is the third stage; setting c=0.2, b=0.3, a=0.5, in the first stage, at 18- At 19:00, the total number of valid channels A, B, and C in the unit time period is 3, 1, and 1, respectively. In the second phase, the unit time is 18-19 points. The total number of valid channels A, B, and C is 3 respectively. 2, 0, in the third stage, the unit time period of 18-19 points, the total number of effective channels A, B, C are 1, 1, 1 respectively, then the effective frequency can be obtained. The weight value of track A is: S=0.5×1+0.3×3+0.2×3=2, and the weight value of effective channel B is: S=0.5×1+0.3×2+0.2×1=1.3, effective channel C The weight value is: S = 0.5 × 1 + 0.3 × 0 + 0.2 × 1 = 0.7. Since the effective channel A has the largest weight value, the effective channel A is set to an ideal channel of the unit time period of 18-19 points in a day. Similarly, the ideal channel of other unit time periods of the day can be generated in the above manner. Therefore, when the user turns on between January 18th and 19th, the boot channel selection module 4 of the smart TV 100 automatically selects the effective channel A as the boot channel.

Or, in this embodiment, when 6 N At 10 o'clock, the data analysis module 3 generates the ideal channel information table according to another weight calculation formula, and the weight calculation formula is S=b×K+c×L, where S is a certain unit time period within a certain day. a weighted value of a valid channel being viewed, and the consecutive N days are divided into a first phase including the first day to the fifth day and a second phase from the sixth day to the tenth day, and L is the In the first phase, the total number of days in which the effective channel is viewed during the unit time period, c is a weight value of the effective channel that is viewed during the unit time period in the first phase; K is in the second phase The total number of days that the active channel is viewed during the unit time period, and b is a weight value of the effective channel that is viewed during the unit time period in the second phase; where b>c and b+c=1.

And the data analysis module 3 calculates a weight value of all effective channels in each unit time period in a day according to the weight calculation formula, and sets the effective channel having the largest weight value in each unit time period as each unit time period. The ideal channel, and when there are more than two valid channels with the same weight value and the largest effective channel in the unit time period, the valid The day in the channel information table that is closest to the smart TV boot date, the effective channel having the largest weight value in the unit time period is the ideal channel of the unit time period.

For example, as shown in the section of the effective channel information table in Table 2:

Table 2 records the effective channels of the unit time period from February 1st to February 7th for 7 consecutive days (N=7), 18-19 points, and February 1st to February 5th is the first stage. From February 6th to February 7th, it is the second stage; set c=0.4, b=0.6, in which the total number of days of effective channels A, B and C is 2 in the unit time period of 18-19 points in the first stage. 2, 1, in the second phase of the unit time period 18-19 points, the total number of effective channels A, B, C are 1, 1, 0, then the weight value of the effective channel A can be obtained: S = 0.6×1+0.4×2=1.4, the weight value of the effective channel B is: S=0.6×1+0.4×2=1.4, and the weight value of the effective channel C is: S=0.6×0+0.4×1=0.4. The effective channel A and B have the same weight value and the largest value, of which February 7 is At 18-19 points, there is a valid channel B with the largest weight value in the unit time period, and there is also a valid channel A with the largest weight value in the unit time period at 18-19 points on February 6th, but since February 7 is compared with 2 On the 6th of the month, February 7th is the day when the user is powered on. Therefore, the data analysis module 3 sets the effective channel B to the ideal channel of the unit time period of 18-19 points in a day. Similarly, the ideal channel for other unit time periods of the day can be generated as described above. Therefore, when the user turns on between 18-19 on February 8, the smart TV 100 automatically selects the effective channel B as the boot channel.

Or, when 2 N At 5 o'clock, the data analysis module 2 of the embodiment generates the ideal channel information table according to another weight calculation formula, and the weight calculation formula is S=M, where S is a certain unit time period within a certain day. a weight value of the effective channel to be watched, M is the total number of days in which the effective channel is viewed from the first day to the Nth day; and the data analysis module calculates all the unit time periods in the day according to the weight calculation formula. a weight value of the effective channel, and setting the effective channel having the largest weight value in each unit time period as the ideal channel of each unit time period, and when the unit time period has more than two weight values and the largest When the effective channel is in the effective channel information table, the effective channel having the largest weight value in the unit time period is the ideal channel of the unit time period.

For example, as shown in the effective channel information table section provided in Table 3:

Table 3 records the effective channels of the unit time period from March 1 to March 4 for 4 consecutive days (N=4), from March 1 to March 4, at 18 -19 points The total number of valid channels A, B, and C of the unit time period is 2, 1, and 1, respectively. It can be seen that the weight value of the effective channel A is: S=2, and the weight value of the effective channel B is: S= 1. The weight value of the effective channel C is: S=1. Since the weight value of the effective channel A is the largest, the data analysis module 3 sets the effective channel A to an ideal channel of the unit time period of 18-19 points in a day, and the ideal channel of other unit time periods of the day is generated as described above. . Therefore, when the user turns on between March 19th and 18th, the smart TV 100 automatically selects the effective channel A as the boot channel.

Therefore, the above embodiment collects the user's recent continuous N by the data collection module 1 of the smart TV 100. N 15) watching the channel information in the day, and by using the channel information collected by the data collection module 1 by the data analysis module 3, generating an ideal channel information table for recording the channel that the user wants to watch most of the time in a day. When the user turns on the smart TV 100, the boot channel selection module 4 of the smart TV 100 can find the ideal channel information table according to the current unit time period, so as to automatically switch to the channel that the user wants to watch at the moment of booting, and realize the boot channel. Automatic selection does achieve the efficacy and purpose of the present invention.

However, the above is only the preferred embodiment of the present invention. The scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the present invention in the scope of the invention and the patent specification are still within the scope of the invention.
