As shown in FIG. 1, the IPTV reception system according to the present invention includes a content storage unit 101, a content summary engine 103, and a content playback unit 109.

The IPTV reception system according to the present invention can summarize and reproduce content data for a predetermined playback time. For example, if the reproduction time of the content data is 45 minutes and the predetermined reproduction time is 15 minutes, the IPTV receiving system according to the present invention summarizes and reproduces the content data for 15 minutes. At this time, the IPTV reception system according to the present invention reproduces the contents corresponding to 15 minutes by combining the divided sections of the content data which are divided into predetermined units. Here, the division of the content data does not mean that the files are divided as individual files, but the division of the content data to be reproduced by the content reproducing unit 109 described later. In more detail, the content data having a playback time of 45 minutes may be divided into, for example, three minutes, and the content playback unit 109 may have five sections corresponding to three minutes from the content data for 15 minutes. To play. The five sections are determined according to priority information of the divided sections.

Hereinafter, the IPTV reception system according to the present invention will be described in more detail.

The content storage unit 101 stores content data divided into sections in the predetermined unit and priority information of the divided sections.

The predetermined unit may be a unit of time as described above as an embodiment. The priority information is information indicating a section to be reproduced first among the divided sections of the content data. That is, levels may be assigned to each of the divided sections, and the order of sections to be reproduced first is determined according to the levels. The priority information is information including all levels corresponding to the divided sections.

 For example, as described above, the content data having a playback time of 45 minutes may be divided into 15 sections in units of 3 minutes, and a level is assigned to each of the 15 sections. In addition, a section with a higher level may be preferentially reproduced.

The priority information may be provided by a contents provider (CP) or an IPTV service provider. In addition, the content storage unit 101 may store a plurality of content data, and the priority information may include information about a priority between the plurality of content data.

The content summary engine 103 includes a content summary information generation unit 105 and a content summary information storage unit 107.

The content summary information generating unit 105 generates content summary information so that the content data can be reproduced during the predetermined reproduction time based on the priority information. That is, the content summary information generating unit 105 determines the number of sections to be reproduced among the divided sections of the content data during the predetermined playback time, and generates the determination result as the content summary information. In this case, the content summary information generation unit 105 determines a section to be played first within the predetermined playback time using the priority information.

For example, as described above, when the reproduction time of the content data is 45 minutes, the predetermined reproduction time is 15 minutes, and the content data is divided into units of 3 minutes, the content summary information generation unit 105 is configured to give the priority. Five sections having high priority are determined using the information, and the determination result is generated as the content summary information.

The content summary information storage unit 107 stores the content summary information. That is, the content summary information storage unit 107 stores the content summary information until the content reproduction unit 109 reproduces the content data, for example, at the request of a user.

The content reproducing unit 109 reproduces the content data based on the content summary information. In more detail, when a user requests a playback, the content playback unit 109 reads the content data from the content storage unit 101 and reads the content summary information from the content summary information storage unit 107. The content playback unit 109 reproduces a predetermined section from the content data by using the content summary information.

Meanwhile, the content summary engine 103 may generate the content summary information only for content data according to a user's request among the plurality of content data stored in the content storage unit 101. The predetermined play time may also be set by the user.

If the predetermined playback time is set by the user, the content summary engine 103 does not exceed the playback time set by the user and the content summary is played so that the content data can be played for the closest time to the playback time set by the user. Generate information.

The user may request reproduction of the content data, the predetermined playback time, and the content playback unit 109 through a user interface (UI). The user interface is described in detail later with reference to FIG. 6.

The second section 202, the third section 203, the fourth section 204, the seventh section 207, the eighth section 208, the ninth section 209, and the twelfth section in the priority information. Since the 212, the 13th section 213, and the 14th section 214 are the third level, which is the highest level, or the second level, which is the middle level, the content summary engine 103 uses the second section 202 and the third section. 203, the fourth section 204, the seventh section 207, the eighth section 208, the ninth section 209, the twelfth section 212, the thirteenth section 213, and the fourteenth section ( The second content summary information 225 is generated so that 214 can be reproduced. If the predetermined playback time is 30 minutes, the content summary engine 103 generates content summary information so that the first section 201 having the fastest playback time among the first levels can be further reproduced.

The content summary engine 103 generates content summary information such that the divided sections are reproduced in chronological order within the predetermined playback time. For example, in the second content summary information 225, the second section 202 has a lower level than the third section 203, but the content summary engine 103 includes the second section 202 because the second section 202 has a lower level than the third section 203. Second content summary information 225 is generated such that the second section 202 is reproduced before the third section 203.

Meanwhile, the content summary engine 103 may generate content summary information according to the level requested by the user. For example, when the user requests the highest third level, the content summary engine 103 generates the first content summary information 203. When the user requests the second level, which is the highest third level and the intermediate level, the content summary engine 103 generates the second content summary information 205.
