It will be apparent to those skilled in the art that the components shown in FIG. 1 are components necessary for explaining the present invention, and that a channel automatic change system may have more components than those described above .

The channel automatic change server 100 extracts program start, end time, and advertisement start end time data for each channel using an EPG (Electronic Program Guide), and generates a program streaming time table for each channel. The channel automatic changing server 100 extracts a channel through which a program is streamed and switches to an extracted channel at the time when an advertisement starts on a channel being viewed using the generated program streaming time table for each channel. That is, by automatically switching to a different channel to which the program broadcast is transmitted in the commercial streaming time, the viewer is prevented from being manually exposed to the advertisement.

The digital broadcast receiving apparatus 200 receives the channel information extracted from the automatic channel change server at the advertisement start time and receives the program streaming signal broadcasted on the extracted channel. The digital broadcast receiving apparatus 200 may include an ACRS (Auto Channel Routing System) 210 and a settop 230. The ACRS 210 performs adaptive routing. For example, when the ACRS 210 receives the channel information extracted from the channel automatic change server 100, the ACRS 210 selects an optimal channel according to the system state at the reception time And transmits it to the settop 230 so as to communicate using the optimal channel.

For example, the software may be machine language, firmware, embedded code, and application software. In another example, the hardware can be a circuit, a processor, a computer, an integrated circuit, a circuit core, a sensor, a micro-electro-mechanical system (MEMS), a passive device, or a combination thereof.

The data management module 110 extracts program start time, end time, and advertisement start end time data from a plurality of broadcast streams including time information and creates a database. The data management module 110 stores the one or more priority channel information set by the viewer, Make the information database. The interest field information is category information including a program that is watched with special interest by viewers such as news, entertainment, and movies. Specifically, the data management module 110 updates and manages time data in which each channel is switched from a program to an advertisement or from an advertisement to a program. This can be performed by using the EPG or by receiving broadcast transmission time information in advance to the server subscriber. The data management module 110 stores the personal information of the registered viewers and stores the priority channel information set by the viewer and the interest field information of the viewers in order to improve the satisfaction of the automatic channel change. . In addition, the data management module 110 groups the channels associated with each interest field, and stores the matching fields of interest and channel groups. For example, news and current events are grouped and matched to general news channels, and entertainment and entertainment fields are grouped after matching drama, movie, and entertainment channels.

The control module 130 extracts program start, end time and advertisement start end time data for each channel from the data management module 110 and generates a program streaming time table for each channel. The program streaming time table for each channel is generated by classifying the types of broadcasts transmitted from each channel on the basis of time into programs and advertisements and including time information for switching from the program to broadcasting or vice versa. For example, the program streaming time table for each channel may be generated by binarizing code, graph, or the like by matching the advertisement to 0 and the program to 1 based on the time axis. Thereafter, the control module 130 extracts a channel through which the program is streamed at the start of the advertisement using the program streaming time table, and switches the channel to one of the extracted channels, thereby preventing exposure of the viewer's advertisement.

 The switching channel extracting unit 133 extracts any one of a plurality of priority channels broadcasted by the program at the advertisement start time of the broadcast streamed on the channel selected by the viewer by using the broadcast time table and the advertisement conversion time table of the table generating unit .

The arithmetic operation unit 135 calculates a program streaming time when switching to each of the priority channels by assuming channel switching occurrence for each channel using the broadcast time table and the advertisement switching time table. Thereafter, the operation unit 135 combines the optimal channel switching order in which the program streaming time becomes the maximum according to the calculation result. For example, the operation unit 135 may combine a plurality of channels included in the priority channel information set by the viewer to generate an optimal switching sequence in which the program streaming time of each priority channel is maximized when channel switching occurs, In a case where channel switching occurs by combining a plurality of channels matched to respective fields of interest of a viewer, an optimal switching order in which a program streaming time of each of the plurality of channels is maximized is generated, or a plurality of channels When channel switching occurs, an optimal switching sequence is generated in which a program streaming time of each of a plurality of channels selected at random is maximized.

The content generation unit 139 classifies content according to interest information, and generates broadcast content based on interest information set by a viewer. For example, the interest information can be classified according to category topics according to program information broadcast on each channel such as political / current affairs, movie, entertainment / entertainment, etc., and the content generation unit 139 collects and generates can do.

 The control unit 137 receives the selected switching channel information from the switching channel extractor 133 and controls the channel switching or receives the content generated from the content generating unit 139. If the self- . For example, if the viewer agrees to watch the interest content generated by himself / herself instead of the advertisement, the control unit 137 streams the broadcast content generated by the content generation unit 139 at the advertisement time of the current channel without switching the channel. 4A to 4B, the process of filtering commercial broadcasting without changing the channel automatically will be described in more detail.

4A is an example of a program streaming time table for each channel according to an embodiment of the present invention.
