Genre and display timing of M broadcast, and one CM
It starts when the display time is set.

First, the video source switching section 206 sequentially reads out the video information recorded in the program broadcast recording section 204 and outputs it to the monitor device 3 (step 100).
1). As a result, the broadcast contents of the program channel selected by the program selection section 207 and separated and decoded from the digital broadcast signal by the program channel separation / decoding section 202 are displayed on the monitor device 3.

As described above, the program broadcast recording unit 2
In 04, the broadcast content of the program channel separated and decoded from the digital broadcast signal by the program channel separation / decoding section 202 is always written.

Next, the switching state monitoring unit 210
It is determined whether the display timing of the CM broadcast set by the reception pattern setting unit 208 has come (step 100).
2). For example, when the display timing is set in the interval period between the CM display and the CM display, the switching state monitoring unit 210 uses the monitoring device 3 that has been performed immediately before.
After the display of the CM broadcast on the receiving device ends, or the elapsed time after the power of the receiving apparatus is turned on is measured, and when the elapsed time reaches the set interval period, the CM is displayed.
It is determined that the broadcast display timing has come.

For example, when the display timing is set according to the progress of the broadcast contents of the program channel displayed on the monitor device 3, the switching state monitoring unit 210 separates the control channel by the control channel separation unit 205. A broadcast content code corresponding to the program channel of the broadcast content displayed on the monitor device 3 included in the specified control channel is acquired, and the broadcast content specified by the status code and / or the progress code of the broadcast content code is obtained. When the progress reaches the set progress, it is determined that the CM broadcast display timing has come.

If it is determined in step 1002 that the CM display timing has come, the switching state monitoring unit 210
Suspends reading information from the program broadcast record 204 (step 1003).

Next, the switching state monitoring unit 210
A CM channel broadcasting a CM corresponding to the genre set by the reception pattern setting unit 208 (if there are a plurality of set genres, select one of them) is separated and decoded from the digital broadcast signal. , And issues an instruction to the CM channel separation / decoding section 203. The video source switching unit 206 is instructed to switch the video information to be output to the monitor device 3 from the information recorded in the program broadcast recording unit 204 to the information from the CM channel separation / decoding unit 203. put out. As a result, the video information displayed on the monitor device 3 is switched from the program broadcast to the CM broadcast (step 1004).

Note that the switching state monitoring unit 210
A CM channel that is broadcasting a CM corresponding to the genre set by the reception pattern setting unit 208 is a broadcast content code corresponding to the CM channel among broadcast content codes included in the control channels separated by the control channel separation unit 205. It is identified by examining the content code.

For example, CM reception pattern setting section 208
In the case where the genre set in the above is "food", from among the broadcast content codes of the respective CM channels, the code corresponding to the "food" (in the above example, the code "2")
01 "). Then, the CM channel corresponding to the broadcast content code having the code is set as the CM channel to be separated / decoded by the CM channel separation / decoding section 203.

Next, the switching state monitoring unit 210 measures the time from when the output to the monitor device 3 is switched to the CM broadcast, and the time passes the CM display time set by the CM reception pattern setting unit 208. It is determined whether or not it has been performed (step 1005).

If the CM display time has not elapsed, the switching state monitoring unit 210 determines the progress status of the CM from the broadcast content code of the currently displayed CM channel included in the control channel separated by the control channel separation 205. Find out. Then, it is determined whether or not the CM has finished broadcasting (step 1006). If not, the process returns to step 1005. When the CM channel is finished, the CM channel which broadcasts the CM to be displayed is detected according to the CM genre and the genre selection pattern set by the CM reception pattern setting unit 208, and the CM channel is set to the digital broadcast. An instruction is issued to the CM channel separation / decoding section 203 to separate / decode from the signal (step 1007). Thereafter, the process returns to step 1005.

Specifically, when one CM genre is selected on the interactive screen shown in FIG. 7, a CM channel on which a CM of the genre is being broadcast is detected, and the CM channel is changed to a digital broadcast signal. To the CM channel separation / decoding section 203 so as to separate / decode from the CM channel.

When two or more CM genres are selected on the interactive screen shown in FIG. 7, the following is performed.

If the item “same genre” 331 is selected on the dialogue screen shown in FIG.
A CM channel that broadcasts a CM of the same genre as the genre selected in step 4 is detected, and an instruction is issued to the CM channel separation / decoding section 203 to separate / decode the CM channel from the digital broadcast signal.

When the item “related genre” 332 is selected on the dialogue screen shown in FIG. 8, a CM channel displaying a CM of a genre related to the genre selected in step 1004 from the two or more genres. And instructs the CM channel separation / decoding section 203 to separate / decode the CM channel from the digital broadcast signal.

The detection of the related genre may be performed by storing the relevance of each genre of the CM in the switching state monitoring unit 210, or
A code indicating the group to which the genre belongs may be added to the content code of the broadcast content code, and this may be performed by checking this.

When the item "mix" 333 is selected on the dialogue screen shown in FIG. 8, a genre is randomly selected from the two or more genres, and a CM channel on which a CM of the genre is broadcast is detected. Then, it instructs the CM channel separation / decoding section 203 to separate / decode this CM channel from the digital broadcast signal.

In step 1005, the monitor device 3
When it is determined that the time since the output to the CM broadcast is switched to the CM broadcast has exceeded the CM display time set by the CM reception pattern setting unit 208, the switching state monitoring unit 210
Reading of the information recorded in the program broadcast recording unit 204
Reading is resumed from the address where the reading was interrupted in step 1003 (step 1008).

As described above, by restarting the reading from the address where the reading was interrupted, it is possible to prevent the contents of the program broadcast to be displayed on the monitor device 3 from being lost in the middle. If new information has already been written at the address where the reading was interrupted, reading is restarted from the oldest information among the information recorded in the program broadcast recording unit 204. By doing so, it is possible to reduce the missing part of the content of the program broadcast to be displayed on the monitor device 3.

Note that an actual program broadcast (a program broadcast included in a digital broadcast signal received by the receiving unit 201)
The time lag between the broadcast and the program broadcast displayed on the monitor device 3 can be adjusted using the near-on-demand technology.

For example, it is assumed that broadcast station 1 broadcasts the same broadcast contents at different times on a plurality of program channels. The switching state monitoring unit 210 detects a time lag between an actual program broadcast (a program broadcast included in a digital broadcast signal received by the receiving unit 201) and a program broadcast displayed on the monitor device 3. Let me measure. Then, the shift is determined by the program channel (A) being received and A
A program channel that broadcasts the same content as the channel (B
), The program broadcast recording unit 204 is reset, and the program selection unit 2 is switched to switch the channel selection from the A channel to the B channel.
Give instructions to 07.

In this manner, the time difference between the actual program broadcast and the program broadcast displayed on the monitor 3 can be adjusted.

After the processing in step 1008, the switching state monitoring unit 210 sends the video information output to the monitor device 3 to the video source switching unit 206 from the information output from the CM channel separation / decoding unit 203. , An instruction to switch to the information recorded in the program broadcast recording unit 204. As a result, the video information displayed on the monitor device 3 is switched from the program broadcast to the CM broadcast (step 1009).

In the first embodiment of the present invention, according to the genre and display timing of the CM set by the user,
The display screen of the monitor device 3 is switched from program broadcasting to CM broadcasting. For this reason, the user may select C of a favorite genre.
M can be displayed on the monitor device at a desired timing. In addition, for advertisers of CM, their CM
Can be presented to a user who is interested in, so that advertisement can be efficiently performed.

In this embodiment, after the program channel separation / decoding section 202 separates and decodes the program channel, the program broadcast recording section 20 having a ring buffer structure
4 is recorded. However, the present invention is not limited to this. The separated program channel may be recorded in the program broadcast recording unit 204 without decoding, and may be decoded when read from the recording unit 204.

The program broadcast recording section 204 may be omitted, and the information obtained by separating / decoding the program channels by the program channel separating / decoding section 202 may be directly input to the video source switching section 206.

In the present embodiment, the switching state monitoring unit 210 changes the CM channel broadcasting the CM of the genre set by the CM reception pattern setting unit 208 to the broadcast content of each CM channel included in the control channel. Detected by referring to the code. However, the present invention is not limited to this. For example, when a plurality of CM channels are prepared for each genre, the correspondence between each of the plurality of CM channels and the genre is stored in the switching state monitoring unit 210 to broadcast a CM of a desired genre. It is possible to detect the CM channel that is running.

Since the CM broadcast may be slightly delayed in time, the CM channel separation / decoding section 203 is provided with a memory for storing the separated / decoded information. Of the information stored in the memory, the CM video may be provided from the beginning by sequentially reading the information from the head part of the CM.
