On the other hand, according to the open IPTV providing system according to an embodiment of the present invention, the guide server 200 may further comprise a user disposition analysis module 260.

The user tendency analysis module 260 analyzes the content preference tendency of the user based on the user preference information stored in the user preference information management module 210.

The user tendency analysis module 260 may analyze the content preference tendency of the user by assigning a higher weight to the content recently selected by the user among the user preference information. For example, a weighting factor of 50 is given to the genre that the user has selected immediately before (one time), a weight of 30 for the genre selected two times before, and a weight of 10 for the genre selected three times before. As a result, the recent content preference trend of the user can be analyzed.

In addition, the user disposition analysis module 260 may use a Marcov Chain Model.

More specifically, when the user preference information is referred to as a genre, the variables X = {x ₁ , x ₂ , x ₃ ,. , x _i ,… , x _c }, and can be expressed as X = {drama, sports, news, movie, document, etc.} (the total number of genres that the user can select is c). As shown in FIG. 4, the preferred content to be selected at time t + 1 may be predicted based on the content consumption record from the time t before t + 1 to the time t-r + 1 for which the probability is to be obtained. Where r is the order of the Markov chain model, and means the number of past content selections. x _i denotes the i-th content, i denotes 1, 2,... can be one of c.

That is, the probability that content i is selected as the preferred content at t + 1 time is

Can be.

n _xi denotes patterns X (t), X (t-1),..., from time t-r + 1 to the time t selected by the user. , The probability of spending x _i at t + 1 along X (t-r + 1).

m means the order counted from time t. When m = 1, it means the order at time t, and when m = r, it is the order at time t-r + 1. w _m is a weight for content selection from t to t-r + 1 and may have a value between 0 and 1, in which case the total is 1. b _{(m, xi )} is a boolean that indicates whether the x _i genre has been selected for order m. b _{(m, xi )} is 1 when genre of x _i is selected in order _m, and b _{(m, xi )} is 0 when genre of x _i is not selected in order _m .

More specifically, for example, when there are contents for four genres of {sports, news, movie, documentary}, the Jacob order r = 3, and the weight w _m for the content selection is recent from time t to t-r + 1. If the selected content is assigned a higher weight, w _t = 0.5, w _{t −1} = 0.3, and w _{t −2} = 0.2. If the user's past content selection is a sports genre at time t, a news genre at time t-1, and a movie genre at time t-2, the estimated probability that the user will select a sports genre at time t + 1 is (1 × 0.5 + 0 × 0.3 + 0 × 0.2) = 0.5, the expected probability that the user will select a news genre at time t + 1 is (0 × 0.5 + 1 × 0.3 + 0 × 0.2) = 0.3, and the user will have time t + The expected probability of choosing a movie genre at 1 is (0 × 0.5 + 0 × 0.3 + 0 × 0.2) = 0.2.

Unlike PCs, IPTV systems continue to watch content and generally focus on high quality playback of content rather than the processing power of the system. Therefore, the content collection module 220 adjusts the schedule for collecting the content through the schedule module so as to efficiently collect the content without degrading the playback quality of the content.

On the other hand, in the open IPTV providing system according to an embodiment of the present invention, the guide server 200 may be configured to further include an integrated billing module.

The integrated billing module performs a function of calculating the billing according to the provision of the preferred content when the preferred content is provided to the user. In other words, the charge for the provision of the preferred content for the content providing server including the preferred content is calculated. The present invention is an open IPTV providing system, the content providing server may be any content providing server including the content, not a fixed one content providing server, in this case, the user is not a single content providing server, but several different contents Each content may be provided from a providing server. However, at this time, it is very cumbersome to charge the user for each content providing server individually, so that the user calculates the integrated billing, which is the integrated billing for the content viewed by the user for a certain period of time. In order to calculate the charge for the content providing server, an ID for identifying the content providing server may be set for each content providing server.

The set-top box (STB) 300 refers to a device connected to a television to receive an incoming signal from the outside and convert the signal appropriately to display the contents on the television.

In more detail, the set top box 300 may include a second transmission module 310 and a decoding module 320.
