Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of a broadcast video automatic recording apparatus according to the present invention, in which 1 is a receiver for receiving a television broadcast from an antenna 2 and 3 is a signal from the receiver 1. This is an AV output device that receives a video signal and an audio signal output to lines L1 and L2 and outputs them as received AV (video and audio). In this embodiment, as will be described in detail with reference to FIG. 2, broadcast program information received from the antenna 2 together with video and audio information is separated by the receiver 1 and input to the extraction circuit 4 via the signal line L3. The extraction circuit 4 extracts program data such as a channel number, broadcast date and time, a keyword characterizing each program (hereinafter referred to as metadata) from the broadcast program information, and outputs the program data to the signal line L4.

5 is a program information file for storing the program data extracted by the extraction circuit 4 in a table format, and 6A and 6B are A for digitizing the video signal and the audio signal output from the receiver 1, respectively. / D conversion circuit, 7 is an image file for storing video and audio digitized by the A / D converter, and 8A and 8B are digitized video read from the image file 7, respectively. A D / A converter for converting audio into analog signals. The video signal and audio signal output from the D / A converters 8A and 8B are input to the AV output device 3 and output as recorded video. .

  9 is a processor for performing control operations necessary for automatic recording, 10 is a program memory for storing various programs executed by the processor, 11 is a data memory for storing various data tables to be described later, Reference numeral 12 denotes a keyboard used for inputting data and commands, and reference numeral 13 denotes a mouse used for moving the cursor on the display screen of the output device 3 and selecting an icon or command displayed on the screen. A device 14 indicates an internal bus 14 for connecting the various elements described above.

FIG. 2 shows an example of a receiver 1 applied to a broadcast video automatic recording apparatus.
Here, a case will be described in which program information, video and audio information for a plurality of channels are packet-multiplexed and broadcast at each carrier frequency selected by the receiver 1.

  The receiver 1 demodulates a tuner 21 connected to the antenna 2, an A / D converter 22 that converts the output signal of the tuner 21 into a digital signal, and an output signal of the A / D converter 22 (for example, QPSK). A demodulating / correcting circuit 23 that demodulates and corrects the error, a descrambling circuit 24 for descrambling the encrypted packet included in the data stream output from the demodulating / correcting circuit 23, and a scramble A packet separation circuit 25 is provided for extracting program information packets and video and audio packets of the target program from the released data (packet) stream.

  The program information packet taken out by the packet separation circuit 25 is output to the signal line L3, and the video packet and audio packet of the target program are supplied to the decoding circuit 26, and are included in these packets in the decoding circuit 26. For example, video and audio data encoded by the MPEG standard are decoded. The digital video signal and audio signal output from the decoding circuit 26 are converted to analog signals by the video and audio D / A converters 27 and 28, respectively, and then output to the signal lines L1 and L2.

  The receiver 1 further includes an internal bus 29 for connecting the elements 21 to 26 described above, and a receiver processor 30, a program memory 31, a data memory 32, and an interface 33 connected to the internal bus. The command from the processor 9 shown is given to the receiver processor 30 via the interface 33, and the video and audio signals of an arbitrary channel designated by the processor 9 can be taken out to the signal lines L1 and L2. Note that a receiver having the same configuration as that shown in FIG. 2 is introduced in, for example, Journal of the Institute of Image Information and Television Engineers Vol. 51, No. 9, pp 1364 to 1369.

Next, various data tables formed in the data memory 11 and the program information file 5 will be described.
FIG. 3 shows a search keyword table 60 formed in the memory 11.
The search keyword table 60 includes a plurality of records 60-1, 60-2,..., And each record includes a reservation number 61 and a plurality of search keywords 62 corresponding thereto. Examples of the search keyword in this case include a term indicating a program genre, a title name of a movie or a drama, a name of a singer or an actor, a type of sport, a team name, and the like.
The search keyword table 60 is created when the user operates the keyboard 12 or the mouse 23 on the input screen generated by the key input processing program 100 and inputs a reservation number and a search keyword.

FIG. 4 shows a program information table 70 formed in the program information file 5.
Each record 70-1, 70-2,... In the program information table 70 includes a channel number 71, broadcast date (start time and end time) data 72, and a plurality of terms (metadata) 73 indicating the contents of the program. These data are extracted from the program information packet by the extraction circuit 4.

  Program information is repeatedly broadcast in a format in which, for example, information for one week is updated every day by program information packets of each data stream. When the broadcast frequency band is divided into m and N channels of video are broadcast by packet multiplexing at each frequency, a total of N × m channels of video can be received. Here, when a program information packet in a data stream carried by one frequency includes program information for N channels broadcast in the data stream, in order to collect program information of all channels in the frequency band. Therefore, it is necessary to extract program information while switching the reception frequency by the tuner 21. On the other hand, if the program information packet includes all program information for N × m channels in a data stream of any frequency, all program information can be displayed at an arbitrarily selected frequency without switching the frequency. Can be collected.

  The program information update program 200 is periodically executed at a cycle according to the update frequency of the broadcast program information, and activates the extraction circuit 4 via the signal line L7. In the case of a broadcast format that provides all program information in one data stream, the program information table 70 can be edited by organizing the data output from the extraction circuit 4 within a certain period. In the case of a broadcast format that requires switching of the reception frequency, the program information table 70 is stored by instructing the receiver 1 to switch the frequency via the signal line L7 and repeating the above-described operation for each frequency. Can edit.

FIG. 5 shows a configuration of a recording reservation table 80 generated by collating the search keyword table 60 and the program information table 70.
The recording reservation table 80 includes a plurality of reservation records 80-1, 80-2,..., And each reservation record includes, for example, a reservation number 81, a channel number 82, a broadcast date and time (broadcast start time and end time) 83, metadata. 84, a matching rate 85, and a status code 86 are included. The reservation number 81 is the same as the reservation number 61 registered in the search keyword table 60, and the program information such as the channel number 82, the broadcast date and time 83, and the metadata 84 is copy data from the program information table 70. . In place of the metadata 84, a search keyword that matches the metadata may be stored. The coincidence rate 85 indicates a matching result between the search keyword 62 registered in the search keyword table 60 and the metadata 73 included in the program information table 70.

The status code 86 indicates the status of each reserved record, and is set to “0” in the initial status. For example, when metadata associated with one program satisfies a search condition in a plurality of reservation numbers registered in the search keyword table 60, a plurality of records having the same program but different reservation numbers are formed in the recording reservation table 80. Is done. In this case, the record with the smallest reservation number is left as a recording management target, and the status code is set to “1” and “duplicate” for other records with the same program. When the contents of the recording reservation table are displayed, for the record designated to be canceled by the user, the status code is “2” “recording cancel”, and the record of the program being recorded is “3” “recording”, The record that has been recorded is “4” “recorded”.
In FIG. 5, the reservation records are shown arranged in the order of the reservation numbers, but the arrangement of the reservation records may be in the order of the broadcast start time and the order of the reservation numbers, for example.

FIG. 6 shows a flowchart of a recording reservation update program 300 for updating the recording reservation table 80.
The recording reservation update program 300 is automatically executed when the contents of the search keyword table 60 are changed and when the program information table 70 is updated. First, an unnecessary record is deleted from the recording reservation table 80 (step 301). ). Here, the record to be deleted is a recorded record (status code “4”) and a duplicate record (status code “1”) whose broadcast end time has passed. Next, the search keyword table 60 and the program information table 70 are collated, and a record is added to the recording reservation table 80 for the newly searched program (step 302), and the recording reservation table is corrected (step 303). ).

  In the correction processing step 303, for example, the records in the registration reservation table 80 are sorted in order of broadcast date and time, in the order of reservation numbers. If there are records whose broadcast times overlap completely or partially with other programs, the programs are the same. Except for the case of (1), one of them is left and another record overlapping with this is deleted.

For example, if the reservation numbers are set in order of priority, a record with a young reservation number is left, and other records having the same broadcast time are deleted. If there are multiple records with the same reservation number that overlap in time, a program with a fast broadcast start time or a program with a high matching rate may be given priority. If priority is assigned regardless of the numerical value of the reservation number, priority information is stored in the search keyword table 60, and each record of the recording reservation table 80 includes the priority information. The record selection described above can be performed using the priority information. In addition, there are some users who want to watch a large number of programs at the expense of one program, rather than leaving a single program with a long broadcast time to sacrifice a large number of short-time programs. It is desirable to be able to specify a rule for determining which of these is prioritized for each user.
In the table 80 after the above-mentioned broadcast time duplication check, a record having the same program is detected, and the status code is set to “1” indicating “duplication”. As a result, a recording reservation table 80 in which recordable programs are arranged in the order of broadcast start time is obtained.

FIG. 7 shows details of the collation step 302 between the search keyword table 60 and the program information table 70 in the recording reservation update program 200.
Each record in the search keyword table 60 is checked against all the records in the program information table 70, and based on the matching rate between the keyword 62 and the metadata 73, it is determined whether or not the program should be reserved for recording.

  In FIG. 7, symbol ∀ means that when there are a plurality of data or records, the value of the variable is changed and these data or records are sequentially selected. For example, step 310 is a variable t. By changing each value, each record (60-t) registered in the search keyword table 60 is designated one after another, and the following steps 311 to 317 are repeated for all the records registered in the search keyword table 60. Means.

  First, the value of the variable n indicating the matching rate is set to the initial value 0 (step 311), and then all the metadata 73 registered in the record 70-i of the program information table 70 (step 312), the search keyword All the keywords 62 (step 313) registered in the record 60-t are sequentially compared (step 314), and if they match, 1 is added to the variable n (step 315). When collation with all the metadata of the program information record 70-i is completed for all the keywords of one search keyword record 60-t, the value of the variable n indicating the number of matches is evaluated by the evaluation function (step 316). When the evaluation result is positive, the program information record 70-i is registered in the recording reservation table 80 (step 317). In this case, the recording reservation table 80 is checked and registered as a new record only when the same record does not exist.

When the evaluation function is n, programs with one or more metadata matching the search keyword are to be recorded. When the evaluation function is n−T, a program whose matching number n is equal to or greater than the threshold value T is to be recorded. The evaluation function is n / Ni-Ti or n / Kjt-Tjt (where Ni is the number of metadata registered in the program information record 70-i, and Kjt is the search keyword registered in the search keyword record 60-t. , Ti and Tjt are threshold values), a program that matches at a certain ratio or more with respect to the number of metadata or the number of keywords is registered.
A weight Wjt may be given to each search keyword in advance and stored in the search keyword table 60, and the matching keyword n may be calculated by adding the weights of the matching keywords.

8 and 9 show a recording management table 90 and a recording related information table 95 formed in the data memory 11 by an automatic recording program 400 described later.
The recording management table 90 includes a plurality of records 90-1, 90-2,... Indicating the relationship between the reservation number 91 and the file name 92 of each video (including audio) stored in the image file 7. As indicated by 90-2 and 90-3, when the same program matches a plurality of search conditions with different reservation numbers, separate records are generated. The recording related information table 95 is for storing the relationship between the recording file name 92 and the program information. In this example, as the program information, the broadcast date and time 93 and the metadata 94 obtained from the recording reservation information table 80 are stored. Is included.

FIG. 10 shows a flowchart of the automatic recording program 400.
The automatic recording program 400 is executed at the end of execution of the recording reservation update program 300 or when an interruption from a recording start timer described later occurs. First, it is checked whether or not the recording end timer is set (step 401). The recording end timer is used to generate a timer interrupt when the program being recorded ends. The fact that the recording end timer is in a set state means that video data is currently stored in the recording file 7. Means that the program is being recorded. In this case, the program is terminated without doing anything.

  If the recording end timer is not in the set state, it is checked with reference to the recording reservation table 80 whether there is a program to be recorded (hereinafter referred to as a recording candidate) <step 402>. The recording candidate is determined by comparing the broadcast start time stored in the broadcast date and time 83 of the recording reservation table 80 with the current time and determining whether or not the program has reached the broadcast start time. If there is no recording candidate, the process proceeds to step 408 to search for the next recording candidate.

  If there is a recording candidate in step 402, the channel number 82 is designated and the receiver 1 is instructed to start recording via the signal line L8. In FIG. 5, it is assumed that each program reserved for recording can be specified by channel number 82 and broadcast date and time 83. However, when the receiver 1 needs to specify a channel selection frequency for specifying a program, each recording reservation is made. A frequency identifier is also stored in the record 80-i, and the reception frequency may be indicated to the receiver 1 at the time of the recording start command.

Upon receiving the recording command, the receiver 1 adjusts the tuner 21 to the target frequency, and the packet separation circuit 25 separates the video packet and audio packet of the designated channel from the received data stream, and records them on the signal lines L1 and L2. Audio signal and video signal to be output are output. These signals are converted into digital signals by the A / D converters 6A and 6B and stored in an image file.

  At this time, a new file name 92 is given to the recorded program, and based on the contents of the record corresponding to the recording candidate in the recording reservation table 80 and the file name 92, the recording management table 90 and the recording related information table are recorded. A new record indicating the recorded program is added to 95 (step 405). In the recording reservation table 80, the recording candidate status code 86 is changed to a code indicating recording (step 406), and the broadcast end time stored in the recording candidate record is set in the recording end timer. (Step 407).

  In step 408, the next recording candidate whose broadcast start time is closest to the current time is searched from the recording reservation table 80. If there is no recording reservation record corresponding to this, this program is terminated. If there is a recording reservation record corresponding to the next recording candidate, the broadcast start time stored in the record is set in the recording start timer (step 410), and this program ends.

  As described above, when the automatic recording program 400 is executed, a timer interrupt can be generated at the recording start time by setting a recording start timer for the next recording candidate, and when an interrupt from the recording start timer occurs. If the recording start command in step 404 is executed, recording candidates can be selected one after another from the registration records in the recording reservation table 80, and a recording command can be generated by timer interruption.

  When an interruption occurs from the recording end timer, as shown in FIG. 11, a recording end instruction is issued to the receiver 1, and the data storage operation in the recording file 7 is stopped (step 451). Since the recording end timer sets a new time when recording of the next recording candidate starts, the recording operation automatically starts and ends according to the broadcast date and time (broadcast start time and end time) provided as program information. Can be repeated alternately.

Even if the recording operation is completed for all the records registered in the recording reservation table 80, the automatic recording program 400 is executed when a new reservation record is added to the recording reservation table 80 by the recording reservation update program 33. Therefore, videos of new programs can be stored in the image file 7 one after another. Each time a new video (program) is stored in the image file 7, a new record is added to the recording management table 90 and the recording related information table 95 shown in FIGS. Thus, a recording file unique to each user is configured.

  The accumulation status of the video data in the image file 7 can be communicated to the user by outputting the contents of the recording management table 90 and the recording related information table 95 to the display screen of the AV output device 3 in an appropriate display format. Furthermore, when the user specifies a program on the storage status display screen, by accessing the image file 7 with a file name corresponding to the program, and when the user specifies a reservation number, the reservation number Are successively accessed with the corresponding file names, the stored video can be read from the image file 7 and output to the display screen.

FIG. 12 shows an example of a recording status display screen showing the storage status of video data in an image file.
In FIG. 1A, reference numeral 110 denotes a display screen or a window formed on a part of the display screen, 111 denotes a screen title, and 112 (112-1 to 112-6) correspond to reservation numbers 61 and 91. A cylindrical figure (icon) represented by the recorded file is shown.
In this embodiment, as shown in FIG. (B), each cylindrical figure 112 has a graph display including a current data accumulation amount 112A indicated by diagonal lines and a memory remaining amount 112B indicated by white lines. Each cylindrical figure 112 is provided with a number 113 indicating a reservation number, a number 114C indicating a recording time corresponding to the full length 112C of the cylinder, and a number 114A indicating a recording time corresponding to the data accumulation amount 112A.

  In this way, by displaying the video storage status in the image file 7 as a graph with a graphic corresponding to the reservation number, the user can easily determine the recording status at a glance and easily specify the file to be recorded and played back. Can provide. In addition, when displaying the amount of accumulated data in a graph for each reservation number, it is necessary to allocate a file capacity (recording time) in advance for each reservation number. A rough recording capacity (recording time) is displayed, and when a search keyword is registered, the user can specify a recording file capacity for each reservation number and store this in the search keyword table 60. As an alternative method, the storage capacity of the image file 7 may be equally distributed by the number of reserved recording files, and the storage data amount of each recording file may be displayed as a bar graph.

The recording status display screen 110 may be used to form a recording file with a new reservation number or to modify a registered search keyword. For example, when one of the displayed cylindrical figures (icons) 112-i is designated with the cursor and the user double-clicks the mouse, the search keyword input screen with the reservation number indicated by the designated icon is displayed. displaying, if the user clicks the mouse, it is sufficient to output the display screen of the program information related accumulated video recording file with the reservation number.

On the search keyword input screen, the user can input an arbitrary keyword from the keyboard 12. Instead of the input operation from the keyboard, as shown in FIG. 13, a group of keywords prepared in advance may be displayed on the input screen 120, and the user may select a term from this by operating the mouse.
In FIG. 13, 121 is a reservation number display area, 122A and 122B are button areas for up / down operation of the reservation number displayed in the display area 121, and 123-1 to 123-4 are examples of keywords. Show. In this embodiment, a plurality of terms representing the genre name of the program are displayed on the first input screen, and when one of them is selected, a group of terms related to the genre is displayed on the next screen, which is necessary. The user is asked to specify keyword terms one after another while scrolling the screen according to the above. In this case, for example, as shown in the term 123-3, if the term selected by the user on each input screen is highlighted, it becomes easy for the user to grasp the input keyword.

  FIG. 14 shows an example of a program information display screen 130 related to the stored video of the recorded file, where 131 is a reservation number display area, 132 is a recorded program information display area, and 133 is an instruction to play back the recorded video. This is a button area.

  When any icon 112-i indicating a recording file is clicked on the recording status display screen 110 shown in FIG. 12, a reservation number corresponding to this icon is displayed in the number display area 131 and the recording management table 90. The program information (for example, broadcast date 93 and metadata 94) of the recording file corresponding to the reservation number obtained by searching the recording related information table 95 is displayed in the program information display area 132.

  On the other hand, when the screen title area 111 is clicked on the recording status display screen 110, the number display area 131 displays a character string indicating the entire image file 7, for example, “ALL”, and the program information In the display area 132, program information of all recording files stored in the recording related information table 95 is displayed. If the extraction circuit 4 can extract the program title from the program information packet received by the antenna separately from other general metadata, the program title is stored as a separate item in the tables 80 and 95. This may be displayed in the display area 132.

  When the user designates any program record displayed in the display area 132 and clicks the play button area 133 on the program information display screen 130, the recorded video of the designated program is read from the image file 7, Output to the display screen. When all the programs are specified and the play button is clicked, or when the play button is clicked without specifying the program record, all the programs in the display area 132 are sequentially read from the image file, Output to the display screen.

  The reproduced video data may be automatically deleted from the image file 7, but an area for designating data deletion is provided in the display area 132 of the program information display screen 130 to reproduce the video data. Recording data and management data may be deleted from the image file 7 and the tables 90 and 95 for the program specified by the user later.
