  FIG. 1 is a block diagram showing the configuration of an embodiment of a video recording / reproducing apparatus 1 according to the present invention. Specifically, the video recording / reproducing apparatus 1 has a function of receiving a digital broadcast, and has a function of receiving content from a content distribution server on the network connected to the Internet via a transmission / reception unit.

  The antenna 3 is an antenna for terrestrial digital broadcasting or satellite digital broadcasting for receiving broadcast radio waves transmitted from the broadcasting station 2. The tuner 4 selects a broadcast signal of a desired channel from broadcast signals of terrestrial digital broadcast or satellite digital broadcast. The demodulator 5 demodulates corresponding to the modulation system of each digital broadcast. The digital terrestrial broadcast signal is demodulated into a digital video signal and an audio signal by OFDM (Orthogonal Frequency Division Multiplexing) demodulation, and the satellite digital broadcast signal is demodulated by PSK (Phase Shift Keying) demodulation and output to the signal processing unit 6. Is done.

  The signal processing unit 6 selectively performs predetermined digital signal processing on the digital video signal and audio signal supplied from the demodulator 5 and outputs them to the video processing unit 7 and the audio processing unit 8. The signal processing unit 6 has functions such as an MPEG (Moving Picture Experts Group) encoder, an MPEG decoder, and a video / audio decoder.

  The video processing unit 7 converts the digital video data input from the signal processing unit 6 into a format that can be displayed on the display device 9 or arbitrarily adjusts the display color, and outputs it to the display device 9. To display the image. The audio processing unit 8 converts the digital audio data input from the signal processing unit 6 into an analog audio signal that can be reproduced by the speaker 10, and then outputs the analog audio signal to the speaker 10 to reproduce the audio. The display device 9 or the speaker 10 may be installed in the same casing as the video recording / reproducing device 1. In that case, a portion surrounded by a broken line in FIG. 1 is included in the same casing as the video recording / reproducing apparatus 1.

  In the video recording / reproducing apparatus 1, all operations including the above-described reception operation are comprehensively controlled by a CPU (Central Processing Unit) 12. The demodulator 5, the signal processing unit 6, the video processing unit 7, and the audio processing unit 8 are connected to the CPU 12 via the data bus 11.

  A RAM (Random Access Memory) 13 is a read / write memory that stores various data necessary for the data processing of the CPU 12, and operates as a buffer memory that stores video data and the like. A ROM (Read Only Memory) 14 is a read only memory and stores a control program executed by the CPU 12.

  The operation receiving unit 15 receives an operation signal transmitted from the operation unit 16 and transfers the operation signal to the CPU 11. The operation unit 16 is, for example, a remote controller using wireless communication using infrared rays, a wired or wireless mouse, a keyboard, and the like, and sends an operation signal. The operation receiving unit 15 receives operation signals from the remote controller, mouse, keyboard, and the like.

  The video recording / reproducing apparatus 1 is connected to the Internet 18 via a transmission / reception unit 17.

  The recording device 19 is a recording device including a flash memory or an HDD (Hard Disk Drive). Although the recording device 19 is connected to the data bus 11, the recording device 19 is equipped with an interface means for recording and reproducing information, and records data in the flash memory or HDD via the interface means. Play.

  FIG. 2 is a block diagram showing a program configuration of the program reservation process of the video recording / playback apparatus 1. The program reservation processing program is stored in the ROM 14, and the CPU 12 starts the program reservation processing program when the power is turned on or broadcast data is input.

  The program preview extracting means 20 is a means for determining and extracting whether or not the video of the broadcast program currently being viewed by the user is a program preview of the program. To determine whether the video being viewed is a program preview, recognition of a telop displayed in the video, EPG data from a broadcasting station, data broadcast, program preview information provided via a network, or the like is used. Data broadcasting includes program-linked data broadcasting and complementary data broadcasting (program information), and data related to other broadcasting services performed on the same channel is broadcast.

  The telop recognition means 21 detects telop character information (captions such as headlines and person names in the broadcast program video) displayed on the screen, recognizes them as telop characters, and converts them into text codes. The text code is stored in the RAM 13 as telop data. The telop characters include character information such as future broadcast date and time, program name, performer name character data, “don't miss” and “hope expectation”, and various character information related to the program notice.

  The metadata recognizing means 22 includes, for example, data such as broadcast time and performer data in EPG data, display of program contents, and the data creation date, creator, data May include format, title, etc. The metadata recognizing means 22 selectively extracts metadata related to the program notice and stores it in the RAM 13 as metadata.

  The network data recognizing means 23 recognizes the program notice information via the network transmitted simultaneously with the broadcast or the program notice information via the network transmitted at a time different from the broadcast, and stores it in the RAM 13 as metadata.

  The program preview extraction means 20 determines that the program preview is based on the telop data, metadata, and network data stored in the RAM 13, and extracts it as program preview data. The program being viewed by the user is loop-recorded at a predetermined time interval using a partial area of the RAM 13, but when the program preview extraction means 20 determines that the program is predicted, the program preview data recording means 24 The loop recording is interrupted, the latest recording data is retained, and the recording data of the program preview is recorded and managed as the program preview data 25. Further, metadata such as the broadcast time and title of the program to be notified is extracted and recorded as program notification data 25 including the metadata.

  The preference data generating means 26 generates preference data 29 from a viewing tendency database 27 that stores past viewing tendency data of the user of the video recording / playback apparatus 1 and a keyword database 28 that stores keywords input by the user.

  The viewing tendency database 27 is a database in which metadata of programs that have been reserved for recording or viewing by the user in the past is accumulated and arranged in descending order of occurrence frequency for each metadata classification. This database is ring data of the most recent predetermined number of recording reservations or viewing reservations (for example, 50) due to memory limitations.

  The keyword database 28 is a database that stores text-based keywords that are arbitrarily stored by the user. The keyword database 28 can have a predetermined hierarchy according to the importance of the keyword. For example, if there is a keyword of sports and gourmet, if sports are set to high importance ranks and gourmets are set to low importance ranks, sports programs are always determined for preference in the preference determination described later, but gourmets are determined for preference. It may not be done.

  The preference determination unit 30 compares the program preview data 25 recorded by the program preview data recording unit 24 with the preference data 29 generated by the preference data generation unit 26 to determine whether the program matches the user's preference. The meta information of the program preview data 25 and the preference data 29 are matched, and when the similarity exceeds a certain threshold, it is determined that the program matches the preference. Many methods for calculating the degree of similarity have already been proposed, and any of these methods may be used. Details are not described here.

  The automatic recording reservation means 31 is a function that can be set by the user to automatically make a recording reservation when it is determined that the program preview data 25 matches the user's preference. If the automatic recording reservation is set to ON, the automatic recording reserved flag 32 is set. The automatic recording reservation completion judging means 33 checks whether or not the automatic recording reservation flag 32 is set. If the automatic recording reservation flag 32 is set, it is determined that the user has set the automatic recording reservation to the ON state, and if not, it is determined that the automatic recording reservation is in the OFF state.

  The prompt screen display means 34 functions when the automatic recording reservation completion determination means 33 determines that automatic recording reservation is not completed. In other words, when the user sets from the beginning so that the program preview automatically matches the user's preference so that the recording reservation or the viewing reservation is made, the prompting screen display means does not operate.

  The prompt screen display means 34 pops up a prompt screen 51 in a part of the display screen 50 of the display device 9, for example, the upper right corner. The prompt screen 51 will be described later. The prompting screen 51 is generated by the prompting screen generation means 35 and the prompting screen data 36 is generated and displayed. The reminder screen generation unit 35 receives the program preview metadata and the program preview recording data from the program preview data recording unit 24, and reconfigures the screen so that the screen prompts the user to record on the prompt screen 51. The reminder screen 51 displays the title of the program preview, the broadcast date and time, etc., and also displays viewing reservation, recording reservation, and cancel buttons, which can be arbitrarily selected by the user.

  The recording reservation determination unit 37 determines whether the user has reserved viewing or recording or canceled the recording while the prompt screen 51 is displayed. In a state where the prompt screen 51 is displayed, the user can select any of viewing reservation, recording reservation, and cancellation, and an operation signal is transmitted by a remote controller (not shown) or an operation button on the front or side of the video recording / playback apparatus 1. The recording reservation determination unit 37 checks which signal is the operation signal, and determines whether the viewing reservation, the recording reservation is made, or the cancellation is made.

  The EPG determining means 38 matches the metadata acquired by the metadata recognizing means 22 or the telop data acquired by the telop recognizing means 21 with the EPG data acquired by the metadata recognizing means 22 when extracting the program preview. Then, it is determined whether the program preview program exists as EPG data. Since EPG data cannot be obtained for future programs exceeding one week, the EPG determination means 38 determines that there is no EPG data. If there is EPG data, it is determined that there is EPG data, and recording reservation is performed in units of programs using the EPG data. If it is determined that there is no EPG data, a recording reservation is made based on the start time and end time of the program obtained from the metadata and telop data described above.

  The EPG acquisition means 39 is means for acquiring EPG data from broadcast data. Program data (broadcast time, performers, program contents, etc.) from EPG data up to one week ahead can be acquired. EPG data is acquired periodically (for example, at a predetermined time every day).

  The EPG recording reservation unit 40 makes a recording reservation for each program based on the EPG data. Further, if program data of a program preview is found in newly obtained EPG data, a recording reservation for each program is performed based on the EPG data.

  FIG. 3 is a diagram illustrating an example of the reminder screen 51. As for the prompt screen 51, the prompt screen data 36 is generated by the prompt screen generating means 35, and the prompt screen 51 is displayed in a pop-up on a part of the display screen 50 of the display device 9, for example, the upper right corner. On the reminder screen 51, the title of the program preview, the broadcast date and time, and the like are displayed, and a message asking whether to make a reservation to the user is displayed. Further, buttons for viewing reservation 52, recording reservation 53, and cancel 54 are displayed. In a state where the reminder screen 51 is displayed, the recording reservation 53 is highlighted, and the user can set the recording reservation by pressing a decision button on a remote controller (not shown).

  FIG. 4 is a diagram illustrating another example of the reminder screen. The reminder screen 55 is an example in the case of embedding a video of the corresponding program notice in the reminder screen. As for the program preview embedded video 59, the program preview data recording means 24 receives the recording data of the program preview in which the loop recording is interrupted and the latest recorded data is held by the prompt screen generation means 35, and is displayed on the prompt screen 55 as video data. It is structured data. The program preview embedded video 59 may be a still image.

  The reminder screen 55 is displayed for a predetermined time even after the broadcast of the program preview is finished. In general, a program preview is a video of several tens of seconds to several minutes, and the user's operation is not always completed during that time. In addition, it may take time to recognize the telop, and the reminder screen 55 may not be displayed until the end of the program notice. Therefore, even if the broadcast of the program preview ends, if the display is continued for a predetermined time, the time for the user to operate can be secured. For example, it can be displayed continuously for 3 minutes after the broadcast of the program preview ends. In addition, since the program preview embedded video 59 is embedded in a part of the reminder screen 55, the user can check the content of the program preview with an image even when the program preview broadcast ends.

  FIG. 5 is a flowchart of the program reservation process. In S10, the telop recognition unit 21 detects telop character information in the video, recognizes the telop character in the screen, converts it into a text code, and stores it in the RAM 13 as telop data. The metadata recognizing means 22 selectively extracts metadata related to EPG data or program notice in data broadcasting, and stores it in the RAM 13 as metadata. Further, the network data recognizing means 23 recognizes the program notice information provided via the network and stores it in the RAM 13 as metadata.

  In S11, the program preview extraction means 20 determines whether the video of the broadcast program currently being viewed by the user is a program preview of the program. If the video being viewed is a program preview, the process proceeds to S12, and if not, the process proceeds to an end step.

  In S12, the preference determination unit 30 matches the metadata of the program preview data 25 recorded by the program preview data recording unit 24 with the preference data 29 generated by the preference data generation unit 26.

  In S <b> 13, the preference determination unit 30 determines the similarity between the program preview data 25 and the preference data 29. If the similarity exceeds a certain threshold, it is determined that the program matches the preference, and the process proceeds to step 14. Conversely, if it is determined that the program does not match the preference, the process proceeds to the end step.

  In S14, the automatic recording reservation completion determination unit 33 determines whether or not the automatic recording reservation is set to ON. If it is set to ON, the process proceeds to S15 and is set to OFF. If so, the process proceeds to S18.

  In S15, the EPG determination means 37 matches the metadata or telop data of the program preview with the acquired EPG data. In S <b> 16, the EPG determination unit 37 determines whether a program preview program exists as EPG data. If there is EPG data, it is determined that there is EPG data, and the process proceeds to S17. If it is determined that there is no EPG data, the process proceeds to S20. In S17, the EPG recording reservation unit 39 makes a recording reservation for each program using the EPG data, and proceeds to an end step.

  In S18, the prompt screen display means 34 pops up a prompt screen 51 in a part of the display screen 50 of the display device 9, for example, the upper right corner, and prompts the user to reserve viewing and recording of the program preview. .

  In S19, the recording reservation determination means 37 determines whether the user has reserved viewing or recording, or canceled. If it is determined that the viewing reservation or the recording reservation has been made, the process proceeds to S15. If it is determined that it has been canceled, the process proceeds to the end step.

  In S20, when it is determined that there is no EPG data, the EPG determination means 38 makes a recording reservation by designating the date and time based on the start time and end time of the program obtained from the metadata of the program preview data 25 and the telop data. Do.

  In S21, the EPG acquisition unit 39 acquires EPG data from the broadcast data. When a predetermined time has elapsed, new EPG data is acquired. In S <b> 22, the EPG determination unit 37 determines whether a program preview program exists as EPG data. If there is EPG data, it is determined that there is EPG data, and the process proceeds to S17. If it is determined that there is no EPG data, the process proceeds to S21.

  As described above, the program preview data 25 of the program is extracted from the broadcast program, the user preference data 29 is generated from the viewing tendency of the user and the keywords input by the user, and the program preview data and the preference data are generated. To determine whether the corresponding program is a program according to the user's preference. When it is determined that the program suits the user's preference, a prompt screen 51 or a prompt screen 55 is displayed on the screen 50 of the display device 9 for prompting a recording reservation, and a program preview viewing program is reserved for the user and recorded. Prompt to make a reservation. The user can easily make a viewing reservation or recording reservation by looking at the prompting screen 51 or the prompting screen 55.

  In this way, when the user is interested in watching the program preview, it is not necessary to search for the broadcast time of the program on the screen using the EPG, or to specify the recording time directly by the user. You can easily make a recording reservation. Further, by using telop recognition, it is possible to easily make a recording reservation even at a future date and time when the broadcast schedule of the corresponding program is not included in the EPG data.

  Furthermore, since the reminder screen 51 that prompts the recording reservation is displayed by narrowing down to the program preview in accordance with the keywords and preferences set by the user, the troublesomeness of displaying the program preview that is not of interest can be reduced. Also, even if the broadcast schedule is irregular and the broadcast time is not fixed, such as soccer or F1 (Formula One), the program that interests you will be displayed by prompting you to make a recording reservation. This has the great effect of preventing oversight and forgetting to record.

  Even if the program is scheduled to be aired for more than a week, a recording reservation is temporarily made by designating the date and time, and when the EPG data can be acquired later, it is automatically changed to a program designated reservation. It is possible to save the user from rebooking again. Moreover, since detailed meta information of the recording title can be acquired when changing to the recording reservation designated by the program, it can be reflected in the recording title. Since the display of the reminder screen 51 or the reminder screen 55 prompting the recording reservation does not disappear even after the program preview ends, the user can calmly confirm and reserve the recording.

  FIG. 6 is a block diagram illustrating the configuration of the video recording / reproducing apparatus 60 according to the second embodiment. The same parts as those of the video recording / reproducing apparatus 1 of the first embodiment shown in FIG. The second embodiment is different from the first embodiment in that there are a plurality of tuners 4 (FIG. 6 shows two pieces 4a and 4b).

  The video recording / reproducing apparatus 60 is equipped with two or more tuners, and a predetermined time interval is set by a tuner other than one tuner used by the user for viewing the program among the two or more tuners. A plurality of back programs are switched and received, and program preview data of the program is extracted.

The block diagram shown in FIG. 2 is different from the block diagram shown in FIG. 7 in that the program preview extraction means 20 is replaced with the back program preview extraction means 61 and the program preview data 25 is replaced with the back program preview data 62. There is to be. Others are the same.

  The back program notice extracting means 61 uses a different tuner for one or more back programs other than the program being watched by the user, and shows a program notice broadcast on the back program while zapping at a predetermined time interval. A search is determined from the telop data acquired by the telop recognition means 21 and stored in the RAM 13, and the metadata acquired by the metadata recognition means 22. Zapping refers to frequent switching between channels at a predetermined short time interval. It is possible to search not only for the channel that the user is watching but also for the program preview of other channels.

  The back program notice extracting means 61 switches and receives a plurality of back programs at a predetermined time interval by another tuner and extracts the back program notice data 62 of the back program, and the preference data generating means 26 determines the user from the viewing tendency of the user. Preference data is generated, and the back program notice data 62 and the preference data are collated by the preference determination means 30 to determine whether the back program is a program according to the user's preference. When it is determined that the program meets the user's preference, a reminder screen 51 that prompts the user to make a recording reservation is displayed in a pop-up on the screen 50 of the display device 9 so that the user can make a reservation for viewing and recording a program for the back program preview. Prompt. The user can easily make a viewing reservation and recording reservation by looking at the prompting screen 51.

  As described above, multiple tuners are installed to extract back program trailers other than the channel currently being viewed, and the user is encouraged to reserve viewing and recording reservations for back program trailers. This makes it possible to reduce missed programs and forgetting to record. Since the corresponding back program notice is reproduced in a loop, the contents can be easily confirmed even if the back program notice is provided.

  The present invention is not limited to the above configuration, and various modifications are possible.
