As shown in FIG. 4, the TV GUI main page or MyTV client of the IP set-top box 310 of the subscriber connected to the TV 300 transmits a viewing history information request message to the subscriber profile server 231 to provide a TV middleware server ( Through the channel name (MBC, KBS, SBS ...), broadcasting program type (news, drama, sports, movie, weather, ...), program ID (PID), watching start time, watching end time information. Receives viewing history information, viewing preference information, and unviewed VOD information for each broadcast program, and outputs them on the screen.

The broadcast program ID (PID) includes a broadcast program title and the number classification information.

When providing the IPTV service, the viewer's viewing history information from the user terminal is managed by the subscriber profile DB 232 connected with the subscriber profile server 231, so that in the case of the series, the user can use the VOD content by recommending a program that he did not watch. Can be.

For example, if a viewer who is continuously watching a soap opera 'A' watches 11 episodes without watching 10 broadcasts, the TV screen provides a guide to 10 broadcasts that were not watched at a specific position. It makes it easy to watch through certain shortcuts or EPGs. The viewing history information includes information on the number of times of a series of a specific program for each broadcasting channel.

In addition, the viewing history information and the viewer preference information may be configured in various implementation scenarios, and may be notified when watching the same broadcast program as described above, and the viewing history information on a specific page such as a TV GUI main page or MyTV client, and The viewing preference information may be informed.

5 is a flowchart illustrating a broadcast program linked VOD providing method for providing viewing history information according to the present invention.

The IPTV head-end system 100 transmits broadcast video and audio signals, broadcast data, PSI information, and EPG information about broadcast programs for each channel to the subscriber IP set-top box 310 (step S11).

The personalization authentication server of the IPTTV headend system 100 receives an authentication request message including subscriber information and a set-top box ID (SAID) from an IP set-top box 310 (hereinafter referred to as a user terminal) connected to a subscriber's TV. When the IPTV service subscription is confirmed, the authentication ticket is transmitted to the user terminal (step S12).

After the user authentication, the IPTV headend system 100 transmits the broadcast program data of the broadcast channel selected by the user terminal to the user terminal in a multicast manner (step S13).

The TV middleware server 233 receives the viewing history information request message including the subscriber information and the program ID (PID) at the start time of watching the broadcasting program from the viewing history management program of the user terminal (step S14), and the subscriber profile server ( 231), the subscriber profile server 231 receives the subscriber's viewing history information (channel name, broadcast program type, program ID (PID), viewing start time, viewing end time) from the subscriber profile server 231 (step S15).

The TV middleware server 233 analyzes the PID included in the viewing history information request message received from the user terminal and checks whether it is a series (step S16).

If it is confirmed as a series, the subscriber's viewing history information received from the subscriber profile server 231 is analyzed to determine whether there is a number of times that the subscriber has not watched the series previously broadcasted.

If there is a series of times that the subscriber has not watched, the TV middleware server 233 inquires of the VOD server 110 storing the VOD data and inquires whether the VOD data of the series of times exists (step S17). In this case, the unviewed VOD information is transmitted to the user terminal.

In another embodiment, when a TV GUI main page or a MyTV client of the user terminal is selected, a viewing history information request message may be transmitted to the TV middleware server 233. In this case, the viewing history information of the subscriber is transmitted to the user terminal. The user terminal receives the viewing history information and outputs it to the screen.

If the user terminal determines whether to select the unviewed VOD (step S18) and selects to watch the unviewed VOD at the user terminal, the A / V content request information is transmitted from the user terminal to the VOD server 110, and the VOD server 110 transmits the unviewed VOD stream data to the user terminal in a unicast manner (step S19).

If the unviewed VOD is not selected by the user terminal, the broadcast program currently being viewed is watched as it is.

In another embodiment, the user terminal may be configured to select to watch an unviewed VOD after a broadcast program currently being viewed is terminated.

After viewing of the broadcast program of the selected channel or ending viewing of the unviewed VOD, the viewing history information is transmitted to the subscriber profile server 231 by the viewing history management program of the user terminal. At this time, the subscriber profile server 231 stores subscriber-specific viewing history information received in real time, and updates subscriber-specific viewing history information (step S20).

The viewing history information includes a program ID (PID: Program ID), a viewing start time, and a viewing end time.

Therefore, when viewing a particular program, the subscriber's viewing history information is transmitted from the IP set-top box 310 connected to the TV 300 to the subscriber profile server 231 and the viewer's viewing history information is updated in real time with the subscriber profile DB 232. Therefore, by providing unviewed VOD information for each program, it is possible to recommend a VOD related to a broadcast program not viewed in the case of a series.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art various modifications of the present invention without departing from the spirit and scope of the invention described in the claims below Or it may be modified.

As described above, the broadcast program linked VOD system providing the viewing history information according to the present invention and the method for providing the same, the subscriber by transmitting to the subscriber profile server from the IP set-top box connected to the digital TV when watching a specific program for each broadcast channel To store the viewing history information as a DB, and the TV middleware server provides the subscriber's viewing history information and unviewed VOD information for each program to the user terminal, thereby increasing the VOD sales by recommending the previous conference broadcasting program that was not watched in the case of a series. It works.
