Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television broadcast or a radio audio broadcast and a data broadcast associated therewith.
The present invention relates to a broadcast information recording device that displays an image or reproduces an audio and records the image on a storage medium.
In this specification, "television" is referred to as "television" as an abbreviation for Japanese.

[0002]

2. Description of the Related Art The conventional Internet is often used in a form in which a user actively retrieves desired information. This usage form is “PULL type”
It is called. On the other hand, the Internet is increasingly used in a “PUSH type” usage mode in which data is sent from a broadcasting station to a user one after another, rather than the user actively collecting information. Was. PUS
The data sent by the H-type service is displayed one after another on the user's personal computer display screen.

[0003] However, when using the Internet in ordinary households, the telephone line is often connected to an Internet provider. Therefore, in order to receive the PUSH type data sent from the broadcasting station as needed, it is necessary to keep calling the Internet provider at all times, and there is a problem that the telephone bill becomes very expensive.

On the other hand, an HTML (Hyper T) is used by using a vertical blanking period (VBI) of a terrestrial television broadcast signal.
“Web cast” that superimposes and broadcasts Internet data in ext Makeup Language (Source: Internet ASCII, Vol. 2, N)
o. 5, pp. 166-167, May 1997). In Japan since April 1996,
Four lines during the vertical blanking period of 21 lines of the terrestrial television broadcast signal are allocated as data multiplex broadcasting,
Webcasting is performed on the four-line transmission path.

[0005] In satellite digital television broadcasting, an attempt has been started to superimpose Internet data in HTML format on digitized video information and audio information for broadcasting. In the case of digital television broadcasting, video information, audio information, and data can be uniformly handled as digital information, so that Internet data can be broadcast by television waves without using a vertical blanking period.

When receiving Internet data superimposed on terrestrial television broadcasting or satellite digital television broadcasting, there is no need to use a telephone line, so PUSH-type data transmitted from a broadcasting station as needed. Can be always received at very low cost.

Further, when data is superimposed on a television broadcast, there is an advantage that the television video and the data can be linked to each other and distributed to the user. This makes it possible to distribute data related to television programs, for example,
It is possible to use such as distributing data such as textbooks of teaching materials at the same time as images of educational programs and displaying them in multi-windows on TV screens and PC screens. Also,
By broadcasting new data each time the content or topic of the television broadcast changes, the data content can be changed according to the content or topic.

Further, Intercas started in the United States.
t service (Source: Internet ASCII, Vol.
2, No. 5, pp. 166-167, May 1997), the Internet data transmitted by the television broadcast can be temporarily stored in the storage unit of the receiver, and the viewer is stored. You can view the Internet data slowly later.

[0009] However, in the case of the Intercast receiver, the information recorded in the receiver is only data superimposed on the television video, so that even if the data is linked to the television video, the viewer can view the data alone. There is a problem that can only be seen in.

[0010] For example, when the handling precautions of the product introduced in the commercial video are broadcast as text data along with the commercial video for 15 seconds, Int
The information recorded in the ercast receiver is only the handling precautions of the product, and there is a problem that when the viewer views the data later, the appearance, use, use method, effect, and the like of the product are not known.

That is, in the case of a television program in which television video broadcasting and data broadcasting are linked, the data broadcasting is usually used as means for transmitting supplementary information to television video or television audio, and only data of data broadcasting is transmitted. Even if it is recorded and reproduced later, the viewer cannot always understand the content.

Japanese Unexamined Patent Application Publication No. 9-83977 discloses a device for receiving and recording data linked to a television image when a viewer issues a data recording instruction using a remote controller or the like. 1 shows a television receiver that simultaneously records the data displayed on the television receiver and the television image. According to this receiver, when the recorded data is redisplayed, the data and the television image can be combined and displayed simultaneously, so that there is an advantage that the contents of the recorded data can be easily understood. .

[0013]

However, in the television receiver described in Japanese Patent Application Laid-Open No. 9-83977,
The television image recorded on the storage medium is the image at the time when the viewer issues a data recording instruction using the remote control.If the recording instruction is delayed even a little, a television image unrelated to the data to be recorded is recorded. There is a problem that will be done.

After the data is displayed on the television screen, it usually takes a considerable amount of time before the viewer wants to record the displayed data and issues a data recording instruction by operating the remote controller. . For example, if you do not have a remote control in your hand, you need to search for that remote control and have the operation of holding that remote control in your hand, so after the data is displayed on the TV screen, It is not unusual for it to take 10 seconds to record. In this case, even if the data is not updated for 10 seconds, the television image is advanced for 10 seconds, so that a television image unrelated to the recorded data is recorded together with the data.

[0015] Also, in the above-mentioned Japanese Patent Application Laid-Open No. 9-83977, a broadcast station transmits explicit information specifying a timing at which a television image is to be recorded, so that a viewer does not need to operate a remote controller. Also, there is disclosed a method capable of reliably recording a television image specified by a broadcasting station on a receiver. A similar method is also described in JP-A-8-116520 and JP-A-9-93562.

However, the methods described in these publications require that the broadcasting station embed in the broadcast data information specifying the timing at which the television image should be recorded, and the work at the broadcasting station becomes extremely complicated. There's a problem.

In addition, according to this method, a television image unnecessary for a viewer is also recorded in the receiver, so that the receiver needs a huge storage capacity. There are various scenes to be recorded for each viewer, and it is inappropriate to record all the television images specified by the broadcasting station.

Further, in the device described in Japanese Patent Application Laid-Open No. 9-83977, only data displayed on the television screen at the time when the viewer issues a data recording instruction using a remote controller or the like can be recorded. However, there is a problem that a series of related data groups cannot be recorded as a unit.

For example, suppose that three screens of digital data are broadcast together with a 15-second commercial video, and the television receiver switches and displays three data screens in conjunction with the 15-second commercial video. In this case, 1
If the viewer issues a data recording instruction while the screen is being displayed, only the data of the first screen is recorded at this time, and the data of the second screen and the data of the third screen are Not recorded. Therefore, when the recorded 15-second commercial video and the data linked thereto are simultaneously displayed again, the commercial video is displayed for 15 seconds, but the data is displayed only on the first screen. is there.

By the way, as a method of superimposing data on a television image and broadcasting it, there are text multiplex broadcasting and teletext broadcasting, and an apparatus for storing transmitted character data has been proposed. For example, Japanese Patent Application Laid-Open Nos. 7-73243 and 9-9216 disclose devices for storing character data transmitted by radio wave broadcasting or cable broadcasting.

However, in the case of teletext broadcasting,
Usually, TV image information and character data are independent,
There is no TV video or TV sound linked to character data. For this reason, it is only possible to reproduce character data alone.

In view of the above, a first object of the present invention is to
A broadcast information recording device that receives a television video broadcast or a radio audio broadcast and a data broadcast associated therewith and records the data broadcasted by the data broadcast and the television or radio video or audio. Even if there is no information indicating the timing of recording television or radio video or audio in the broadcast data, and the data recording instruction by the viewer is delayed, the data to be recorded and the video related thereto Or if the recorded data is displayed or played back as an image or sound again, the TV or radio video or sound associated with that data can be played back simultaneously. It is to make.

A second object of the present invention is to provide a broadcast information recording apparatus for receiving a television video broadcast or a radio audio broadcast and a data broadcast associated therewith and recording data broadcast by the data broadcast. An object of the present invention is to make it possible to record not only data displayed or reproduced as an image or a sound at the time when a user issues a data recording instruction, but also a series of related data as a unit.

(Operation at the Time of Data Recording) In the broadcast information recording apparatus of the first embodiment described above, when receiving a TV program broadcast in which TV video broadcasting and data broadcasting are interlocked, data and The corresponding TV video and TV audio are recorded.

FIG. 3 shows a recording processing routine performed by the recording / reproducing processing section 18 in this case. In the recording processing routine 100, first, in step 101, it is determined whether or not the data detection section 5 has detected digital data. Judge.

In this example, the digital data is Internet data in HTML format superimposed on the vertical blanking period of the television video signal as described above. FIG.
Shows an example of the Internet data in the HTML format. When the phrase following “Content-Type:” is “text / html”, data below the text is regarded as the Internet data in the HTML format. I have.

When the digital data is detected by the data detecting section 5, the process proceeds to step 102, where the detected digital data is immediately reproduced by the data reproducing section 6 and output to the video / audio / data output section 3. I do. Thereby, as shown in FIG. 1, the data image 43 of the digital data is displayed on the display screen of the television receiver 40 simultaneously with the television image 42.

When the digital data includes data to be reproduced as sound, the sound is reproduced from the speaker. Hereinafter, a case where the digital data includes only data to be displayed as an image will be described.

Next, at step 103, when the data reproducing section 6 starts reproducing data in the video / audio information input section 8, the analog video / audio information is fetched from the analog demodulation section 2 and converted into digital video / audio information. Convert. The processing in the video / audio information input unit 8 is performed for a predetermined time,
In this example, it is continued for 15 seconds.

Next, at step 104, the 15
The digital video / audio information for seconds is sequentially stored in the temporary storage unit 9. That is, the temporary storage unit 9 starts storing the digital video / audio information at the time when the data reproduction unit 6 starts reproducing the data, and stores the digital video / audio information for 15 seconds in this example. Therefore, in this example, the temporary storage unit 9 has a capacity capable of storing digital video and audio information for at least 15 seconds. However, this time or the storage capacity of the temporary storage unit 9 can be changed as appropriate.

The temporary storage section 9 is, for example, in a ring buffer format as shown in FIG. 6, and by controlling the write address, keeps the sequentially input video and audio information in a ring shape while replacing old information with new information. Overwriting by In this example, the temporary storage unit 9 has a capacity capable of storing video and audio information for 16 seconds. That is, storage addresses a1, a2 ‥‥ a
Each of the sixteen 16 memories can store video and audio information for one second.

As such a storage method, other known methods such as a queuing method and a FIFO method can be used.

In FIG. 6, the oldest data address F10
0 is a pointer pointing to the memory where the oldest video / audio information is stored, and the latest data address F101 is
It is a pointer that points to a memory in which the most recently input video and audio information is stored.

At a point within 15 seconds from the point when the data reproducing section 6 starts reproducing data, the temporary storage section 9 is storing video and audio information. FIG. 6 shows an example of the storage state of the temporary storage unit 9 when 11 seconds have elapsed since the data reproduction unit 6 started reproducing data. Video and audio information is stored.

At a point in time when 15 seconds or more have passed since the data reproducing section 6 started reproducing data, the temporary storage section 9
Has finished taking in the video and audio information, and the temporary storage unit 9 holds the video and audio information for 15 seconds from the start of the data reproduction, as shown in FIG.

The viewer looks at the data image 43 displayed on the television receiver 40, and presses the data selection decision key 52 of the television remote control 50 when he / she wants to record the data.

In the recording processing routine 100 of FIG. 3, next, at step 105, it is determined whether or not a data recording instruction is given by the viewer before detecting or reproducing new data, that is, the data selection decision key 52 is pressed. Is determined.

When a data recording instruction is issued, the process proceeds from step 105 to step 106, in which the data displayed at this time as the data image 43 on the television receiver 40 is recorded in the data storage unit 7 and temporarily stored. The video / audio information stored in the section 9 is recorded in the video / audio information storage section 10.

Further, the processing proceeds to step 107, where the storage address of the data stored in the data storage section 7 in the data storage section 7 and the video / audio information storage section 10 of the video / audio information stored in the video / audio information storage section 10 are set. The information indicating the correspondence relationship with the storage address in the data is stored in the correspondence storage unit 11 together with the information indicating the reproduction start time of the data stored in the data storage unit 7.

FIG. 8 shows the data stored in the data storage unit 7, the video / audio information stored in the video / audio information storage unit 10, and the correspondence information stored in the correspondence storage unit 11 in association with each other. In the correspondence storage unit 11, the identification number as the ID of the correspondence information, the storage address of the data stored in the data storage unit 7, the reproduction start time of the data, and the video corresponding to the data. The storage address of the video / audio information stored in the audio information storage unit 10 is stored.

When the data selection determination key 52 is pressed at a time point of 15 seconds or more after the data reproduction section 6 starts reproducing data, the temporary storage section 9 stores the data as shown in FIG. Since the video and audio information for 15 seconds from the start of the data reproduction is held, the temporary storage unit 9 outputs the video and audio information for 15 seconds to the video and audio information storage unit 10 collectively.

Thereafter, in step 108, the temporary storage unit 9 is cleared by advancing the oldest data address F100 to the position of the latest data address F101.

On the other hand, if the data selection decision key 52 is pressed within 15 seconds after the data reproducing section 6 starts reproducing data, the temporary storage section 9
Since the video and audio information is being stored, the temporary storage of the video and audio information is continued until 15 seconds have elapsed since the start of the data reproduction, and when the temporary storage for 15 seconds has been completed, the 15 seconds are stored. Are output to the video / audio information storage unit 10 in a lump.

Thereafter, in step 108, the temporary storage section 9 is cleared by advancing the oldest data address F100 to the position of the latest data address F101.

If it is determined in step 105 that there is no data recording instruction before the detection or reproduction of new data, the process proceeds from step 105 to step 108,
The oldest data address F100 is replaced with the latest data address F1
By moving to the position 01, the temporary storage unit 9 is cleared.

As shown in FIG. 9, when there is a data recording instruction of a viewer for certain data A,
Is storing video and audio information for 15 seconds from the reproduction start time tAs of data A, that is, at time tA
When the reproduction of the next data B is started at a time tBs before the time tAe 15 seconds after the time s, the data corresponding to the data A, which is 15 seconds from the time tAs to the time tAe, Of the video and audio information, the video and audio information from time tBs to time tAe is also used as the video and audio information corresponding to the next data B.

That is, in this case, the temporary storage unit 9 temporarily stores the video and audio information for 15 seconds from the time point tAs to the time point tAe, as shown in FIG.
The video and audio information for 5 seconds is collectively output to the video and audio information storage unit 10, and the oldest data address F100
Is advanced to the storage address corresponding to the time point tBs when the reproduction of the data B is started. In the case of FIG. 10, the video / audio information after the time point tAe is temporarily stored after the storage address a2.

Therefore, when there is a first data recording instruction for recording data A and a second data recording instruction for recording data B at the timing shown in FIG. From time tBs to time tAe,
The video / audio information stored at the storage addresses a14, a15, a16, and a1 is included in both the video / audio information corresponding to the data A and the video / audio information corresponding to the data B.
This is recorded in the video / audio information storage unit 10.

(Operation at the Time of Redisplaying Data) The data recorded in the data storage unit 7 as described above is transmitted to the television receiver 4.
To redisplay the data to 0, the viewer turns the data selection dial 51 of the television operation remote controller 50 to call the data recorded in the data storage unit 7 one after another.

As shown in FIG. 8 and described above, the correspondence storage unit 11 stores the storage addresses of the data stored in the data storage unit 7 in the data storage unit 7 and the data stored in the storage addresses. The reproduction start time is stored.

When the viewer turns the data selection dial 51 to the left, the recording / reproduction processing unit 18
From the data reproduction start time stored in the data storage unit 7, the data is specified in order from the data recorded last in the data storage unit 7, and called from the data storage unit 7. The called data is processed by the data reproducing unit 6, output to the video / audio / data output unit 3, and displayed again on the television receiver 40. Conversely, when the data selection dial 51 is turned to the right, the data recorded in the data storage unit 7 after the data redisplayed at that time are sequentially redisplayed on the television receiver 40.

When the viewer looks at the redisplayed data and wants to watch the corresponding TV video or listen to the TV sound, the TV operation remote control 50
Is pressed. by this,
As described below, the television image corresponding to the redisplayed data is redisplayed, and the television sound is reproduced.

That is, FIG. 4 shows a redisplay / reproduction processing routine performed by the recording / reproduction processing unit 18 in this case. In the redisplay / reproduction processing routine 200, first, when a certain data is being redisplayed, step 201 is executed. , It is determined whether or not the viewer has requested redisplay reproduction, that is, whether or not the data selection decision key 52 has been pressed.

When a redisplay reproduction request is made, the process proceeds from step 201 to step 202, where the correspondence information reproducing unit 12 redisplays the information stored in the correspondence storage unit 11 at that time. The video / audio information for 15 seconds corresponding to the data is specified, and the specified video / audio information for 15 seconds is stored in the video / audio information storage unit 10.
And processes it, and outputs it to the video / audio / data output unit 3. As a result, the data and the television image corresponding to the data are redisplayed on the display screen of the television receiver 40, and the television sound corresponding to the data is reproduced from the speaker.

(Printing or erasing of data) As described above, with the data recorded in the data storage section 7 being redisplayed on the television receiver 40 by operating the data selection dial 51, the viewer operates the remote controller 50 for television operation. When the data print key 53 is pressed, the data redisplayed at that time is printed by the print processing unit 16, transmitted from the infrared transmission unit 46 to the printer 60, and printed as an image by the printer 60.

Similarly, when the viewer presses the data erase key 54 of the TV remote controller 50 while the data recorded in the data storage unit 7 is displayed again on the television receiver 40 by operating the data selection dial 51, The data redisplayed at that time is deleted from the data storage unit 7 by the data deletion unit 14.

In this case, the correspondence information erasing section 15 specifies the video / audio information corresponding to the data to be deleted from the information stored in the correspondence storage section 11, and converts the specified video / audio information to the video / audio information. The information is deleted from the information storage unit 10, and the correspondence information on the deleted data and the video / audio information is deleted from the correspondence storage unit 11. Therefore, the viewer does not need to separately perform an operation of deleting the video and audio information.

(Modification) In the above example, when the data detection unit 5 detects data, the detected data is immediately output to the data reproduction unit 6, but the broadcasting station should be linked with the television image. The data may be broadcast in advance at a timing earlier than the broadcast timing of the television image.

In consideration of this case, it is preferable that the received data is temporarily stored in a cache memory (not shown), and the data to be displayed at the same time is received and then output to the data reproducing unit 6. In this case, for example, even when the amount of data to be displayed on one screen is large, data for one screen can be simultaneously displayed on the television receiver 40 in conjunction with the progress of the television image.

[0121] Internet data in HTML format usually includes layout information, plain text, moving images, still images, audio, or link information to other Internet data. For example, Internet data in HTML format may be included. When one page is a composite of layout information, plain text, and a still image, the page is output to the data reproducing unit 6 after receiving all of the layout information, plain text, and the still image, which are its components. The configuration is as follows.

Further, the broadcasting station broadcasts data to be linked with the television image in advance at a timing earlier than the broadcasting timing of the television image, and includes information specifying the timing at which the data is to be displayed in the broadcast data. Is included, the broadcast data is temporarily stored in the cache memory, and is output from the cache memory to the data reproducing unit 6 at a designated timing.

In the above example, only the data displayed on the television receiver 40 is recorded in the data storage unit 7 when the viewer presses the data selection decision key 52. From 9, all the data reproduced by the data reproducing unit 6 during the period in which the video and audio information to be recorded in the video and audio information storage unit 10 is being reproduced may be recorded in the data storage unit 7. In this case, when the corresponding information reproducing unit 12 redisplays the television image, a series of data broadcast in conjunction with the television image can be redisplayed in synchronization with the television image.

The storage operation of a series of data groups in this case is
This is shown using FIG. 11 and FIG. As shown in FIG. 11, when the reproduction of the data A is started at the time point tAs, the storage of the video / audio information for 15 seconds in the temporary storage unit 9 is started as described above, and at the time point t1 following the time point tAs. When the viewer gives a data recording instruction, the data A is stored in the data storage unit 7.
And 15 seconds after the time tAs,
Video and audio information for 15 seconds is recorded in the video and audio information storage unit 10 from the temporary storage unit 9.

In this case, as shown in FIG. 11, the time tB during which the video and audio information for 15 seconds is stored in the temporary storage 9
At time s and time tCs, when data B and data C are sequentially received, data B and data C are recorded together in data storage unit 7, and are stored in correspondence storage unit 11 as shown in FIG. The audio-video information storage unit 1
The storage addresses d1, d2, and d3 of the data A, data B, and data C in the data storage unit 7 are stored in correspondence with the storage address m1 of the video / audio information in 0.

When a series of data groups A, B, and C recorded in this manner is displayed again, the data storage unit 7
After the reproduction of the data A recorded in the video data and the video / audio information recorded in the video / audio information storage unit 10 is started,
Data B and data C are sequentially reproduced while observing the time interval of the data reproduction start time between data A, data B, and data C stored in correspondence storage unit 11. Thereby, the video / audio information and the series of data groups A,
B and C can be linked and reproduced.

In the above example, the temporary storage unit 9 starts storing the video and audio information at the time when the data reproducing unit 6 starts reproducing the data. However, when the data detecting unit 5 detects the data, The temporary storage unit 9 may be configured to start storing video and audio information.

In the above example, the video and audio information for 15 seconds from the start of the data reproduction is stored in the temporary storage section 9,
When the viewer issues a data recording instruction, the video and audio information for the 15 seconds is recorded from the temporary storage unit 9 to the video and audio information storage unit 10. One frame is stored as a still image in the temporary storage unit 9, and when the viewer issues a data recording instruction, the one frame of the still image is recorded from the temporary storage unit 9 to the video / audio information storage unit 10. You may.
In this case, the temporary storage unit 9 may be capable of storing at least one frame of still images.

Further, in this case, when redisplaying data,
When the data selection dial 51 is operated and the data selection determination key 52 is pressed, the data recorded in the data storage unit 7 and the still image recorded in the video / audio information storage unit 10 corresponding to the data are transmitted to the television. When the viewer presses the data print key 53 in a state where the data is redisplayed on the receiver 40, the data and the still image redisplayed at that time are processed by the print processing unit 16, and the infrared transmission unit 46 By transmitting the data to 60, the desired data and the corresponding still image can be combined and printed.

Further, a plurality of still images may be stored in the temporary storage section 9. In this case, when the viewer issues a data recording instruction, the plurality of still images stored in the temporary storage unit 9 are displayed in a reduced list on the television receiver 40, and the viewer operates the television operation remote controller 50. By
A still image to be stored can be designated from the list, and the designated still image is stored in the video / audio information storage unit 1.
0 can be recorded.

In the above example, data, video / audio information, and correspondence information are separately stored in the data storage unit 7, video / audio information storage unit 10, and correspondence storage unit 11, respectively. The storage address in the video / audio information storage unit 10 of the video / audio information stored in the video / audio information storage unit 10 corresponding to the data, including the data stored in the data storage unit 7, Information indicating the time at which the data was detected or reproduced may be stored. In this case, since the data storage unit 7 also has the function of the correspondence storage unit 11, there is no need to provide the correspondence storage unit 11 separately.

Data broadcast by data broadcasting is
Other than Internet data in HTML format, for example,
It may be plain text, video, still images, audio, or computer programs.

As a method of transmitting data by broadcast waves of terrestrial television broadcasting, an audio sub-carrier may be used in addition to the vertical blanking period of the television video signal. In data transmission using an audio subcarrier, data is transmitted using frequencies of two free channels of an audio signal. About 9.6 kbp per channel
s because of the transmission capacity of about s.
2 kbps Internet data can be transmitted.

Further, the first embodiment described above can be applied to a receiving system for receiving digital television broadcasts. For example, in satellite digital television broadcasting using artificial satellites, attempts have been made to multiplex and broadcast Internet data in HTML format on digitized television video information and television audio information. Can receive Internet data transmitted at a high speed of about 1.5 Mbps.

(Effect) According to the above-described first embodiment, even when there is no information indicating the timing of recording television video or television audio in the data broadcast by the data broadcasting, the data recording by the viewer can be performed. Even if the instruction is delayed, it is possible to reliably record the data to be recorded and the related television video or television audio. Further, when the recorded data is displayed or reproduced again as an image or a sound, a television image or a television sound related to the data can be reproduced at the same time, so that the contents of the reproduced data can be easily understood. .

[Second Embodiment] In the first embodiment, for example, 15 seconds of television video and television audio from the point in time when data broadcasted by data broadcasting is displayed are stored in the temporary storage unit 9 and viewed. When the user issues a data recording instruction, the television video and the television audio stored in the temporary storage unit 9 are recorded in the video / audio information storage unit 10.

However, it is not always necessary to determine the point in time when the data is displayed as the recording start point of the television video and the television audio. Further, the time length of the television video and the television audio recorded in the video / audio information storage unit is not necessarily required. There is no need to fix.

Therefore, in the second embodiment, when receiving a television program broadcast in which a television video broadcast and a data broadcast are linked, the television video and data including those before the data broadcasted by the data broadcast are displayed. The TV sound is stored in the temporary storage unit, and when the viewer issues a data recording instruction, the TV video and the TV sound including the data before the data is reproduced are recorded from the temporary storage unit to the video / audio information storage unit. I do.

[0139] Specifically, in the second embodiment, a scene change of a television program is detected from a television image or a television sound, and the television image and the television sound of the detected scene are recorded in the data instructed by the viewer to record. Record with. According to this, a semantically coherent video scene can be recorded as data-related television video, so that when the data and the related television video and television audio are reproduced in conjunction with each other, the viewer becomes more likely. The contents become easy to understand.

(Configuration) FIG. 13 shows a functional block configuration of a broadcast information recording apparatus according to the second embodiment. In the receiving system for receiving the terrestrial television broadcast shown in FIG. 1, the first system shown in FIG. In the broadcast information recording apparatus of the fifth embodiment, a recording / reproducing processing section 18 is further provided with a video / audio condition matching section detecting section 19.

The video / audio condition matching section detecting section 19 detects a section in which the received video information or audio information matches a preset condition, and specifically, detects the received video information or audio information. From the TV program scene change.

As a method for detecting a scene change from video information, a known inter-frame difference detection method as described in Japanese Patent Application Laid-Open No. 4-286293 can be used. According to this method, the switching timing of the camera cut can be detected, so that the switching timing of the camera cut can be used as the switching timing of the scene.

Other methods for detecting a scene change include detection results of motion of a person or an object, a change in luminance, a change in color distribution, etc. in video information, and a method of detecting a change in audio information.
It is also possible to use detection results such as a change in volume, a change in voice caller, a voice pattern, and a voice keyword.

Unlike the first embodiment, the video / audio information input section 8 always converts the analog video / audio signal demodulated from the analog demodulation section 2 into digital video / audio information and outputs it to the system bus 4. It shall be. The video / audio condition matching section detection unit 19 detects a scene change from the digital video / audio information from the video / audio information input unit 8.

(Operation at the time of data recording) In the broadcast information recording apparatus of the second embodiment, at the time of receiving a TV program broadcast in which a TV video broadcast and a data broadcast are linked, the data and the corresponding data are handled as follows. TV video and TV audio are recorded.

That is, FIG. 14 shows a recording processing routine performed by the recording / reproducing processing unit 18 in this case.
The video / audio information input unit 8 converts the analog video / audio information from the analog demodulation unit 2 into digital video / audio information.

Next, in step 302, whether the video / audio condition matching section detection section 19 has detected a cut change as a scene change, that is, a camera cut switch, from the digital video / audio information from the video / audio information input section 8. Determine whether or not.

Then, the video / audio condition matching section detecting section 19
Detects a cut change, step 303
Then, the digital video / audio information from the video / audio information input unit 8 is sequentially stored in the temporary storage unit 9. That is, the temporary storage unit 9 starts storing digital video and audio information when the video and audio condition matching section detection unit 19 detects a cut change.

In this embodiment, the temporary storage unit 9 stores
In addition to having a capacity capable of storing 0 seconds of digital video / audio information, the video / audio condition matching section detection unit 19 converts digital video / audio information from the time when a certain cut change is detected to the time when the next cut change is detected. For up to 60 seconds.

That is, the video / audio condition matching section detecting section 1
When the time length of one scene detected by the scene 9 is 60 seconds or more, the video and audio information for 60 seconds from the start point of the scene is stored in the temporary storage unit 9, and detected by the video and audio condition matching section detection unit 19. When the time length of one scene is less than or equal to 60 seconds, the video / audio information for the time length of the scene is stored in the temporary storage unit 9.

Further, the temporary storage section 9 stores the digital video / audio information constantly output from the video / audio information input section 8 while retaining the video / audio information of the previous one scene. As a result, video and audio information of two scenes can be stored at the same time. However, the maximum storage time of one scene and the storage capacity of the temporary storage unit 9 can be appropriately changed.

The temporary storage unit 9 is, for example, in a ring buffer format as shown in FIG. 15, and by controlling the write address, keeps the sequentially input video and audio information in a ring shape, and replaces the old information with the new information. Overwriting by And in this example,
Video and audio information for 7.5 seconds is stored in each of 16 memories at storage addresses a1, a2ａa16.

FIG. 15 shows an example of the storage state of the temporary storage unit 9 at the time when the video / audio information of a certain scene is stored as the video / audio information of the scene, from the storage address a3 to the storage address a8. During the period, the video and audio information of the previous scene is stored, and between the storage address a9 and the storage address a14, the video and audio information of the scene is stored.

In this case, the oldest data address F200
Is the previous one of the two scenes that can be stored in the temporary storage
A pointer pointing to a memory in which the video / audio information at the start of the scene is stored.
Reference numeral 202 denotes a pointer that points to a memory in which video / audio information at the start of one scene after the two scenes that can be stored in the temporary storage unit 9 is stored. The latest data address F201 is the most recently input data. This is a pointer to a memory in which the stored video / audio information is stored.

In the recording processing routine 300 of FIG. 14, next, at step 304, while the video / audio information of the scene is stored in the temporary storage section 9, the data detection section 5
Then, it is determined whether or not digital data, that is, data broadcast by data broadcasting is detected. In this example, the digital data is HTM as shown in FIG.
This is Internet data in L format.

If no digital data is detected by the data detection unit 5 while the video / audio information of the scene is stored in the temporary storage unit 9, the video / audio information of the scene is associated with the digital data. It is determined that the information has not been deleted, the process proceeds to step 311, and the video / audio information of the scene is deleted from the temporary storage unit 9.
Returning to step 303, the video / audio information of the next scene is sequentially stored in the temporary storage unit 9.

In this case, the deletion of the video / audio information of the scene in step 311 is performed by replacing the latest data address F201 with the scene start address F20 as shown in FIG.
This is done by returning to position 2. That is, FIG.
As shown in FIG. 15, since the digital data is not detected by the data detection unit 5 while the video / audio information of the scene is stored in the temporary storage unit 9, the storage addresses a9 to a14 This shows a state in which the video and audio information of the scene stored before is deleted.

However, what has been described above is the case where the time length of the scene is 60 seconds or less. If the time length of the scene is 60 seconds or more, in step 304, the data detection unit is operated during 60 seconds from when the storage of the video and audio information of the scene in the temporary storage unit 9 is started. It is determined in step 5 whether or not digital data has been detected.
Then, the process goes to step 1 to delete the video and audio information for 60 seconds from the start of the scene from the temporary storage unit 9 and then returns to step 303 to return to the next scene instead of the video and audio information of the next scene. Are sequentially stored in the temporary storage unit 9.

If it is determined in step 304 that the data detection unit 5 has detected digital data while the video / audio information of the scene is being stored in the temporary storage unit 9,
Proceeding from step 304 to step 305, the video / audio information of the previous scene already stored in the temporary storage unit 9 is deleted from the temporary storage unit 9.

In this case, the deletion of the video / audio information of the previous scene in step 305 is performed by using the oldest data address F
200 is advanced to the position of the scene start address F202. In this case, the video / audio information of the scene newly stored in the temporary storage unit 9 is held in the temporary storage unit 9 until new data is detected by the data detection unit 5 as described later.

FIG. 17 shows an example in which digital data is detected by the data detection unit 5 while the video and audio information of the scene is stored in the temporary storage unit 9. Digital data is detected at time td2 when the digital data is stored in the storage address a12. For the previous scene, it is assumed that digital data is detected at time td1 when the video and audio information is stored at the storage address a5.

Then, the digital data is detected at time td2 as described above, and as shown in FIG. 18, the oldest data address F200 is advanced to the position of the scene start address F202, as shown in FIG. Then, the video and audio information of the previous scene recorded between the storage address a3 and the storage address a8 is deleted.
At this stage, the scene start address F202 no longer exists.

Even if digital data is detected, as will be described later, until the time when 60 seconds elapse from the start of the scene, or when the scene ends before that time, the scene is not updated until the end time. Are continuously stored in the temporary storage unit 9.

When the storage of the video / audio information of the scene is completed, the scene start address F202 is set next to the latest data address F201 so that the scene is set to the previous scene and the next scene is set to the scene. Advance to storage address.

In the recording processing routine 300 shown in FIG. 14, in step 306, the digital data detected by the data detecting section 5 is reproduced by the data reproducing section 6 and output to the video / audio / data output section 3. . Thereby, as shown in FIG. 1, the data image 43 of the digital data is displayed on the display screen of the television receiver 40 simultaneously with the television image 42.

[0166] The viewer looks at the data image 43 displayed on the television receiver 40 and presses the data selection decision key 52 of the television remote control 50 when he / she wants to record the data.

In the recording processing routine 300 shown in FIG. 14, next, at step 307, it is determined whether or not a data recording instruction is given by the viewer before detecting or reproducing new data, that is, the data selection decision key 52 is pressed. Is determined.

When a data recording instruction is issued, the process proceeds from step 307 to step 308, in which the data displayed at this time as the data image 43 on the television receiver 40 is stored in the data storage section 7 and temporarily stored. The video / audio information of the scene stored in the section 9 is recorded in the video / audio information storage section 10.

Further, the process proceeds to step 309, where the storage address of the data stored in the data storage unit 7 in the data storage unit 7 and the video / audio information of the video / audio information of the scene stored in the video / audio information storage unit 10 Storage unit 10
The information indicating the correspondence relationship with the storage address in the data is stored in the correspondence storage unit 11 together with the information indicating the reproduction start time of the data stored in the data storage unit 7.

If the time length of the scene is 60 seconds or less, at a time after the end time of the scene, or if the time length of the scene is 60 seconds or more, 60 seconds or more from the start time of the scene When the data selection decision key 52 is depressed at the time when the time has elapsed, the temporary storage unit 9 stores
Since the video / audio information from the start time to the end time of the scene or the video / audio information for 60 seconds from the start time of the scene is held as the video / audio information of the scene, the temporary storage unit 9 stores The video / audio information of the scene is output to the video / audio information storage unit 10 in a lump.

For example, in FIG. 18, the video and audio information at the end of the scene is stored in the storage address a12, and when the data selection decision key 52 is pressed thereafter, the data is stored in the storage addresses a9 to a12. The video and audio information from the start point to the end point of the scene is output to the video and audio information storage unit 10 in a lump.

Thereafter, in step 310, the oldest data address F200 is advanced to the position of the latest data address F201, thereby deleting the video / audio information of the scene from the temporary storage section 9.

On the other hand, if the time length of the scene is 60
If the time is less than or equal to seconds, the time before the end of the scene, or if the time length of the scene is 60 seconds or more, at the time when 60 seconds have not elapsed from the start of the scene,
When the data selection determination key 52 is depressed, the temporary storage unit 9 is storing the video / audio information of the scene, and therefore, the temporary storage unit 9 continues for 60 seconds from the end of the scene or from the start of the scene. The storage of the video and audio information of the scene is continued until the time elapses, and when the storage is completed, the video and audio information of the scene is output to the video and audio information storage unit 10 collectively.

For example, in FIG. 18, the video / audio information in the middle of the scene is stored at the storage address a12, and thereafter,
When the data selection determination key 52 is pressed, the video and audio information following the scene is stored after the storage address a13 until the end of the scene or until a lapse of 60 seconds from the start of the scene. After that,
The video and audio information of the scene is collectively output to the video and audio information storage unit 10.

Thereafter, in step 310, the oldest data address F200 is advanced to the position of the latest data address F201, thereby deleting the video / audio information of the scene from the temporary storage section 9.

If it is determined in step 307 that there is no data recording instruction before the detection or reproduction of new data, the process proceeds from step 307 to step 310,
The oldest data address F200 is replaced with the latest data address F2
By moving to the position 01, the video / audio information of the scene is deleted from the temporary storage unit 9.

[0177] As described above, data broadcast by data broadcasting and one scene of television video and television audio including that broadcast at the time when the data is displayed are associated with each other and stored in data. Unit 7 and the video / audio information storage unit 10.

(Operation at the Time of Redisplaying Data) The data recorded in the data storage unit 7 as described above is transmitted to the television receiver 4.
To redisplay the data to 0, the viewer turns the data selection dial 51 of the TV operation remote controller 50 to call the data stored in the data storage unit 7 one after another, as in the first embodiment. The called data is processed by the data reproducing unit 6, output to the video / audio / data output unit 3, and displayed again on the television receiver 40.

When the viewer looks at the redisplayed data and wants to watch the corresponding television image or listen to the television sound, the television operation remote control 50
Is pressed.

As a result, in the correspondence information reproducing section 12,
From the information stored in the correspondence storage unit 11, the video / audio information of one scene corresponding to the data redisplayed at that time is specified, and the video / audio information of the specified one scene is stored in the video / audio information storage. It takes in from the part 10 and processes,
Output to the video / audio / data output unit 3. As a result, on the display screen of the television receiver 40, together with the data, the TV video of one scene corresponding to the data is redisplayed, and the TV sound of one scene corresponding to the data is reproduced from the speaker.

(Printing or erasing of data) As in the first embodiment, the data recorded in the data storage unit 7 by operating the data selection dial 51 is transmitted to the television receiver 4.
0, and the viewer operates the TV remote control 5
When the data print key 53 of 0 is pressed, the data redisplayed at that time is printed as an image by the printer 60.

Similarly, when the viewer presses the data erase key 54 of the TV operation remote controller 50 in a state where the data recorded in the data storage section 7 is displayed again on the television receiver 40 by operating the data selection dial 51, The data redisplayed at that time is erased from the data storage unit 7 by the data erasing unit 14, and the video / audio information of one scene corresponding to the deleted data is stored by the corresponding information erasing unit 15. The data stored in the correspondence storage unit 11 is deleted from the storage unit 11 and the data to be deleted and the correspondence information on the video / audio information of one scene are deleted.
Deleted from

(Modification) The above example is a case where only data displayed on the television receiver 40 is recorded in the data storage unit 7 when the viewer presses the data selection decision key 52. Storage unit 9 to video / audio information storage unit 10
In the period during which the video / audio information to be recorded in the data reproduction section is reproduced, or within the section of one scene specified by the video / audio condition matching section detection section 19, all of the data reproduced by the data reproduction section 6 is stored in the data storage section 7. May be recorded. In this case, when the corresponding information reproducing unit 12 redisplays the television image, a series of data broadcast in conjunction with the television image can be redisplayed in synchronization with the television image.

Also, in the above example, the video and audio information of one scene in a range of up to 60 seconds is stored in the temporary storage unit 9,
When the viewer issues a data recording instruction, the video / audio information of the one scene is stored in the video / audio information storage unit 1 from the temporary storage unit 9.
In the case of recording at 0, one frame of the television video broadcast at the time of the scene change is stored in the temporary storage unit 9 as a still image, and when the viewer issues a data recording instruction, the data of one frame is stored. May be recorded from the temporary storage unit 9 to the video / audio information storage unit 10.

In this case, the temporary storage section 9 may be capable of storing at least one frame of still images. Further, in this case, as described in the first embodiment, when data is redisplayed, desired data and a corresponding still image can be combined and printed.

The second embodiment described above can also be applied to a receiving system for receiving digital television broadcasts.

[Third Embodiment] In the second embodiment, the video / audio condition matching section detecting section 19 detects a scene change of a television program from a television image or a television sound, and the television image of the detected scene is detected. And TV sound are recorded together with the data for which the viewer instructed the recording. However, a scene change of a television program can be detected from the content of data broadcast by data broadcasting.

Therefore, in the third embodiment, when receiving a television program broadcast in which television video broadcasting and data broadcasting are linked, a scene change of the television program is detected from the contents of the data broadcast by the data broadcasting, and the change is detected. The TV video and the TV audio of the detected scene are recorded together with the data for which the viewer instructed the recording. According to this, as in the second embodiment, as a television image related to data,
Because you can record semantically coherent video scenes,
When the data and the related television video and television audio are reproduced in an interlocked manner, the viewer can understand the content more easily.

(Configuration) FIG. 19 shows a functional block configuration of a broadcast information recording apparatus according to the third embodiment. In the receiving system for receiving the terrestrial television broadcast shown in FIG. 1, the second embodiment shown in FIG. In this embodiment, a data condition matching section detecting section 20 is provided instead of the video / audio condition matching section detecting section 19 of the broadcast information recording apparatus of the embodiment.

The data condition matching section detection section 20 detects a scene change of a television program from non-display data or display data in data broadcast by data broadcasting.

The non-display data includes a broadcast program identifier, an information provider identifier, a broadcast station identifier, and the like. The display data includes the above-described HTML format Internet data and text information. Both the non-display data and the display data can be used for detecting a scene change.

For example, in satellite digital television broadcasting which has started broadcasting in Japan, MPEG-2 Systems is used as a packet multiplexing system.
EG-2 Systems is TS (Transport
Stream) A packet having a fixed length of 188 bytes called a packet is used as a basic unit of transmission. The four bytes of the header of this TS packet include a packet identifier (PI
D: packet identifier) includes information for identifying a broadcast program. Specifically, a PID (packet identifier) and a PSI (Pr
ogram Specific Information
A broadcast program can be identified by using a correspondence table separately broadcasted in TS packets called n).

As for terrestrial television broadcasting, as disclosed in JP-A-9-70006, VT
There is an example in which a broadcasting station broadcasts information including a program code of a program being broadcast by superimposing it on a vertical blanking period of a television video signal in order to correctly execute recording reservation of R.

In the receiving system, the broadcast station broadcasts non-display data such as a broadcast program identifier, an information provider identifier, or a broadcast station identifier by the above-described method. , A scene change can be detected from the non-display data.

Further, a scene change of a television program can be detected by analyzing a phrase included in the display data detected by the data detecting section 5.

For example, the aforementioned I, which has been started in the United States,
In the case of using the receiving device of the internet service, text data linked to a television program can be received. This text data is analyzed to extract words or phrases that characterize the content of the TV program, and to detect the time when the words or phrases that characterize the TV video change significantly, thereby changing the content of the TV program. It is possible to detect the point of time.

As words or phrases that characterize the contents of a television program, words or phrases that appear frequently in text data linked to the television program and that do not appear much in text data broadcast by other television programs are appropriate. It is. As a method of extracting such a characteristic word or phrase, an automatic keywording technique for data to be searched, which is generally used for full-text search (full-text search) can be used. The full-text search method is a search method that reads the contents of all texts in text data at the time of search and searches for a document that includes a specified search character string. It is common practice to select and register characteristic words and phrases from data.

More specifically, in the following example, a broadcasting station broadcasts a free keyword corresponding to the content of a television image by superimposing the keyword as non-display data on the television image. 20 is a case where the broadcast free keyword is detected and analyzed to detect a scene change of a television program.

The free keywords to be broadcast and detected include program identification information, program provider information, performer information, data obtained by converting broadcast audio into text, camera operation information obtained by encoding a television camera operation signal, and video at the time of video editing. The information includes video editing information in which editing operations are recorded, information for notifying a scene change intentionally inserted by a television program creator, and the like.

For example, as the program identification information, a G code (a television program identification code manufactured by Gemstar, USA, also called VCR / PLUS) can be used. Further, when the broadcasting station broadcasts the television commercial, if the sponsor company name is superimposed and broadcast as the broadcast data on the commercial video for 15 seconds, the data condition matching section detection unit 20 in the receiving system uses the data for the 15 seconds. By detecting a commercial section, the temporary storage unit 9 can reliably store the entire 15-second commercial video from the beginning to the end.

When a broadcasting station converts a broadcast sound into text by using a well-known voice recognition technique and performs data broadcasting, data obtained by converting the broadcast sound into text can be used as a free keyword.

When a broadcasting station broadcasts information about camera work such as panning, tilting, zooming, bouming, trimming, drilling, cut start, and cut end, the broadcast station broadcasts the scene information from the camera work information. The switching timing can be detected. For example, if you are zooming in and shooting, you often take important images,
The zoomed-in period can be cut out as one scene.

[0203] Alternatively, the broadcast station may detect a cut change from the broadcast television image or television audio, and superimpose the detection result on the television image to broadcast the data. In this case, as the receiving system, a scene change can be easily detected by the data condition matching section detection unit 20 without having a cut change detection function like the video / audio condition matching section detection unit 19 of the second embodiment. can do.

The data condition matching section detecting section 20 analyzes the time series change of these broadcast free keywords, and
By detecting the point in time when the free keyword that characterizes the television image changes significantly, the point in time when the content of the television program changes is detected.

The video / audio information input section 8 always converts the demodulated analog video / audio signal from the analog demodulation section 2 into digital video / audio information and outputs it to the system bus 4. The temporary storage section 9 The other configuration is the same as that of the second embodiment, such as having a capacity to store digital video and audio information for 120 seconds, for example, and storing video and audio information of two scenes simultaneously.

(Operation at the time of data recording) In the broadcast information recording apparatus of the third embodiment, at the time of receiving a TV program broadcast in which a TV video broadcast and a data broadcast are linked, the data and the corresponding data are handled as follows. TV video and TV audio are recorded.

FIG. 20 shows a recording processing routine performed by the recording / reproducing processing section 18 in this case. In the recording processing routine 400, the processing in steps 402 and 404 is the same as that of the second embodiment shown in FIG. It is the same as the recording processing routine 300 according to the second embodiment, except that the processing is different from the processing in steps 302 and 304 of the recording processing routine 300 according to the embodiment.

That is, in the recording processing routine 400 in the third embodiment, first, in step 401,
The video / audio information input unit 8 converts the analog video / audio information from the analog demodulation unit 2 into digital video / audio information.

[0209] Next, in step 402, the data condition matching section detecting section 20 detects and analyzes the non-display data, that is, the above-mentioned free keywords in the data broadcasted by the data broadcasting, thereby changing the scene change. It is determined whether or not is detected.

When the data condition matching section detecting section 20 detects a scene change, the process proceeds to step 403, where the digital video / audio information from the video / audio information input section 8 is temporarily stored as in the second embodiment. Stored in the unit 9.

In the recording processing routine 400, next, in step 404, while the video / audio information of the scene is being stored in the temporary storage section 9, the data detection section 5 displays the display data in the data broadcast by the data broadcast. It is determined whether data has been detected. The header portion of the display data includes information indicating that the data is for display, and in this example, the display data is Internet data in HTML format as shown in FIG. .

The other processing is the same as the recording processing routine 300 in the second embodiment shown in FIG. Therefore, similarly to the second embodiment, the data broadcast by the data broadcasting and the TV video and audio of one scene including the one broadcast at the time when the data is displayed are associated with each other, Data storage unit 7
And the video / audio information storage unit 10.

(Operation at Data Redisplay) Data Storage Unit 7
Is redisplayed on the television receiver 40 in the same manner as in the second embodiment. That is, the viewer turns the data selection dial 51 of the television operation remote controller 50 to call the data stored in the data storage unit 7 one after another. The called data is processed by the data reproducing unit 6 to output the video / audio / data output unit 3.
And displayed again on the television receiver 40.

When the viewer looks at the redisplayed data and wants to watch the corresponding television image or listen to the television sound, the television operation remote control 50
Is pressed.

As a result, in the correspondence information reproducing section 12,
From the information stored in the correspondence storage unit 11, the video / audio information of one scene corresponding to the data redisplayed at that time is specified, and the video / audio information of the specified one scene is stored in the video / audio information storage. It takes in from the part 10 and processes,
Output to the video / audio / data output unit 3. As a result, on the display screen of the television receiver 40, together with the data, the TV video of one scene corresponding to the data is redisplayed, and the TV sound of one scene corresponding to the data is reproduced from the speaker.

(Printing or erasing of data) As in the first or second embodiment, the data recorded in the data storage section 7 is displayed again on the television receiver 40 by operating the data selection dial 51. When the viewer presses the data print key 53 of the television remote controller 50, the data redisplayed at that time is printed as an image by the printer 60.

Similarly, when the viewer presses the data delete key 54 of the TV operation remote controller 50 in a state where the data recorded in the data storage section 7 is displayed again on the television receiver 40 by operating the data selection dial 51, The data redisplayed at that time is erased from the data storage unit 7 by the data erasing unit 14, and the video / audio information of one scene corresponding to the deleted data is stored by the corresponding information erasing unit 15. The data stored in the correspondence storage unit 11 is deleted from the storage unit 11 and the data to be deleted and the correspondence information on the video / audio information of one scene are deleted.
Deleted from

(Modification) Also in the third embodiment, the data is specified by the data condition matching section detecting section 20 during the period when the video and audio information recorded in the video and audio information storage section 10 from the temporary storage section 9 is being reproduced. All of the data reproduced by the data reproducing unit 6 may be recorded in the data storage unit 7 within the section of one scene. In this case, when the corresponding information reproducing unit 12 redisplays the television image, a series of data broadcast in conjunction with the television image can be redisplayed in synchronization with the television image.

As described above as a modified example of the second embodiment, one frame of a television video broadcast at the time of a scene change is stored in the temporary storage unit 9 as a still image, and the viewer May issue a data recording instruction, the still image of one frame may be recorded from the temporary storage unit 9 to the video / audio information storage unit 10.

In this case, the temporary storage section 9 may be capable of storing at least one frame of still images. Further, in this case, as described in the first or second embodiment, when data is redisplayed, desired data and a corresponding still image can be combined and printed.

As already described above, the third embodiment can also be applied to a receiving system for receiving digital television broadcasts.

[Fourth Embodiment] First, Second and Third Embodiments
In any of the embodiments, the data for which the viewer instructed the recording and the TV video and the TV audio corresponding to the data are recorded. However, viewers may want to record only the data broadcast by data broadcasting, or it may be sufficient to record it,
In some cases, it is desired to record not only the data displayed at the time of issuing the data recording instruction but also a series of related data including the data displayed before the data.

Therefore, in the fourth embodiment, when receiving a television program broadcast in which television video broadcasting and data broadcasting are linked,
When the viewer issues a data recording instruction, a series of related data including the data displayed at that time and the data displayed before that is recorded, and the television image and the television audio are recorded. If not.

Specifically, in the fourth embodiment, display data in data broadcast by data broadcasting is stored in a temporary storage unit, and data broadcast from television video or audio or from data broadcasting. For example, a change in the scene of the television program is detected from the non-display data therein. Then, when the viewer issues a data recording instruction, the data displayed in one scene section including that time is recorded from the temporary storage unit to the data storage unit as a series of related data.

(Configuration) FIG. 21 shows a functional block configuration of a broadcast information recording apparatus according to the fourth embodiment. In the receiving system for receiving the terrestrial television broadcast shown in FIG. 1, the third embodiment shown in FIG. Is a modification of the broadcast information recording apparatus of the embodiment of the present invention in which a series of related data groups is recorded as described above.

That is, in this example, when a scene change is detected from, for example, non-display data in data broadcast by data broadcasting, the data condition matching section detection unit 20 described above with reference to FIG. 19 is provided. In addition, the recording / reproduction processing unit 18 includes a data detection unit 5, a data reproduction unit 6, a temporary storage unit 21, a data storage unit 7, and a storage data designation unit 1.

However, the temporary storage unit 21 is provided in FIG.
Unlike the temporary storage unit 9 shown in FIG. 19, the display data is temporarily stored by the data detection unit 5. Further, in this embodiment, since the television video and the television audio are not recorded, the video / audio information input unit 8, the temporary storage unit 9, and the temporary storage unit 9 shown in FIGS.
The video / audio information storage unit 10, the correspondence storage unit 11, the correspondence information reproduction unit 12, and the correspondence information deletion unit 15 are not provided.

(Operation at the time of data recording) In the broadcast information recording apparatus of the fourth embodiment, when a television program broadcast in which a television video broadcast and a data broadcast are linked is received, data is recorded as follows.

FIG. 22 shows a recording processing routine performed by the recording / reproducing processing unit 18 in this case. In the recording processing routine 500, first, in step 501,
It is determined whether the data detection unit 5 has detected display data in the data broadcast by the data broadcast. The header portion of the display data includes information indicating that the data is for display, and in this example, the display data is Internet data in HTML format as shown in FIG. .

When the display data is detected by the data detection unit 5, the process proceeds to step 502, where the detected display data is immediately reproduced by the data reproduction unit 6, and the video / audio / data output is performed. Output to section 3. Thereby, as shown in FIG. 1, the data image 43 of the display data is displayed on the display screen of the television receiver 40 at the same time as the television image 42.

[0231] The viewer looks at the data image 43 displayed on the television receiver 40, and presses the data selection decision key 52 of the television remote controller 50 when he / she wants to record the data.

In the recording processing routine 500 of FIG. 22, next, at step 503, the data displayed at that time is stored in the temporary storage unit 21. In this case, the temporary storage unit 21 has a capacity enough to store the maximum data amount in one scene section.

Next, proceeding to step 504, the data condition matching section detecting section 20 determines whether or not a scene change has been detected from the non-display data in the data broadcast by the data broadcast. Is not detected, the process returns from step 504 to step 501.

On the other hand, when the data condition matching section detecting section 20 detects a scene change, the process proceeds to step 504.
Then, the process proceeds to step 505 to determine whether or not the data recording instruction is given by the viewer during the reproduction of the television video and the audio in the immediately preceding one scene section, that is, whether or not the data selection determination key 52 is pressed. .

If there is a data recording instruction in the immediately preceding one scene section, the process proceeds from step 505 to step 506, in which the display data stored in the temporary storage section 21 in the immediately preceding one scene section is stored. The data is collectively recorded from the temporary storage unit 21 to the data storage unit 7, and
In step 07, the temporary storage unit 21 is cleared, and the process returns to step 501.

At step 505, when it is determined that there is no data recording instruction in the immediately preceding one scene section, the process proceeds from step 505 to step 507, where the temporary storage unit 2
Clear 1 and return to step 501.

As described above, not only the data displayed at the time when the viewer issued the data recording instruction, but also a series of related data, including the data displayed before, is collected. Can be recorded as

For example, as shown in FIG. 24, a commercial scene A, a weather forecast scene B, a commercial scene C, a sports news scene D, and a commercial scene E are sequentially received as television image scenes. During reproduction, a scene change is detected at times ta, tb, tc} from the non-display data linked to the television image of each scene.

For example, when the viewer issues a data recording instruction during the display of the display data D3 during the reproduction of the sports news scene D, the immediately preceding sports E at the start time te of the next scene E News Scene D
Of the display data D1 to D4, which are displayed in one scene section from the start time td to the end time te and stored in the temporary storage unit 21, are recorded in the data storage unit 7 as a series of related data. Will be done.

(Operation at the time of data re-display) When the data group recorded in the data storage unit 7 is re-displayed on the television receiver 40 as described above, the viewer must select the data using the TV operation remote controller 50. By turning the dial 51, the data groups stored in the data storage unit 7 are called one after another. The called data group is processed by the data reproducing unit 6, and
The data is output to the video / audio / data output unit 3 and is displayed again on the television receiver 40. For example, in the case shown in FIG.
When the viewer calls the data group of the scene D of the sports news, all of the display data D1 to D4 are sequentially displayed.
Will be displayed again.

(Printing or Erasing Data) In the fourth embodiment, the data group recorded in the data storage unit 7 is displayed again on the television receiver 40 by operating the data selection dial 51 as described above. When the viewer presses the data print key 53 of the television remote controller 50, the data group redisplayed at that time is printed as an image by the printer 60.

FIG. 23 shows a data printing processing routine performed by the recording / reproducing processing unit 18 in this case. In the data printing processing routine 600, first, in step 601 in a state where a certain data group is displayed again. ,
