Description

  The present invention relates to a digital broadcast recording / playback apparatus that records and plays back a digital broadcast using program information provided from a broadcast station or a program information provider.

  Conventionally, the recording reservation setting for the television broadcast in the recording / playback apparatus has been complicated in operation because the broadcast date and time and the channel have been manually input. Therefore, various proposals for improving operability have been made. These proposals are mainly set using an EPG (Electronic Program Guide) in which program information is provided electronically. In particular, in a VDR (Video Disc Recorder) capable of recording and storing a large number of programs, a program name for identifying a recorded program is indispensable information. The EPG set at the same time is most often used.

  As a program information providing method used in EPG, there is a method in which program information of a broadcaster created by a program information provider is integrated, edited, and provided in a batch. This method includes, for example, a method of providing a video signal by superimposing it on a VBI (Vertical Blanking Interval) of a video signal, a method of providing using a specific information providing channel, and the like. Furthermore, there is a method of providing via the Internet using a server prepared by a program information provider. In this case, program information provided through the Internet (hereinafter referred to as Internet EPG) is described in a programming language such as html (Hyper Text Markup Language) recommended by the World Wide Web Consortium (W3C). It can be displayed and operated by web browser software (hereinafter referred to as web browser). Therefore, if the recording / playback apparatus is equipped with this web browser, it is possible to access the program information provider's server via the Internet and make a program recording reservation directly using the Internet EPG. Even if the recording / playback apparatus is not equipped with a web browser, if the user has an interface function with a personal computer, the user can use the web browser installed on the personal computer on the personal computer to use the Internet EPG program. The program information (program name, subtitle name, program description, broadcast start / end time, etc.) of the reserved program, which is data as a result of the program recording reservation in the table, is acquired, and the acquired program information is recorded in the recording device By transferring to, it is possible to make a program recording reservation.

On the other hand, in digital broadcasting, there is a method in which each broadcaster provides program information superimposed on its own broadcast signal.
As described above, there are a plurality of different types of program information providing methods for one broadcasting system. Accordingly, the broadcast recording apparatus uses a plurality of different types of program information providing methods in the receivable broadcasting system among the broadcasting systems such as terrestrial analog broadcasting, terrestrial digital broadcasting, satellite analog broadcasting, and satellite digital broadcasting. It is possible to acquire program information in combination and use the most effective program information from these program information according to the situation at that time.

  As a system for displaying an EPG on a television screen, for example, there is a G guide system. Since the EPG transmitted from this G guide system includes program information for about two weeks, for example, when only the program name is determined two weeks ago, only the program name is displayed as a full title. As the day approaches, information such as subtitles and performers is included, and the program name may be omitted. Therefore, when searching for a program by using the program name as a keyword and making a broadcast recording reservation, if the program name included in the EPG updated as the broadcast date approaches is omitted, the corresponding program is reliably detected. There were cases where it was not possible.

  Also, in the EPG program information and the Internet EPG program information, the formal program name may be omitted and displayed. In this case, there are a plurality of abbreviation methods for one official program name, and the provision of EPG program information and Internet EPG program information regarding which abbreviation method is used or the degree of omission of the program name. At the discretion of the person. Therefore, the program name before the EPG update may be different from the program name after the EPG update, and even in such a case, the corresponding program may not be reliably detected.

In order to solve the above-described problems, a program name as a keyword for automatically searching for a program to be recorded is registered in advance, and the program name and time information of the program corresponding to the keyword are acquired from the EPG. When the EPG is updated, the program name of the corresponding program is acquired based on the time information. When the program name is omitted, the program name before the EPG update and the program name after the EPG update are obtained. A technique for storing the information in association with each other is disclosed (for example, see Patent Document 1 below).
JP 2004-134858 A (paragraph 0042, FIG. 2)

  However, the technique described in Patent Document 1 does not use an official program name as a name for displaying a recorded program unless an official program name is provided at the time of recording reservation setting. For example, as shown in FIG. 13, if a program selection screen in which the program names are omitted is used, there is a problem that it becomes difficult to select a desired program.

  The present invention has been made to solve the above-described problems, and its purpose is to record and display an official program name as an identifier of a recorded program, or an identifier more easily understood by a user. An object of the present invention is to provide a digital broadcast recording / playback apparatus capable of performing

In FIG. 5, first, in step S501, the digital broadcast receiving unit 103 selects a program information providing channel and receives a broadcast signal. In step S502, a program in the signal processing unit 104 is obtained from the received signal. Program information is extracted by the information extraction unit 123. Next, it is determined whether or not the program information extracted in step S503 is the first capture. If it is the first capture, the processing from step S505 is executed, and if it is not the first capture, that is, the second and subsequent times. If it is capturing, the processing from step S504 is executed. In step S505, the extracted program information is stored in the non-volatile memory 111 as EPG information 114, and in step S507, a program information capturing completion process is executed. On the other hand, in step S504, the newly extracted program information is compared with the program information stored as the EPG information 114 to determine whether the program information has been updated. If the program information has not been updated as a result of the determination, the process of step S507 is executed. If the program information has been updated, the EPG information 114 on the nonvolatile memory 111 is updated with the program information extracted in step S506. Subsequently, the process of step S507 is executed.
<Recording reservation processing>
FIG. 6 shows an example of a recording reservation procedure using EPG. In FIG. 6, first, an electronic program guide is displayed in step S601. FIG. 3A shows a display example at this time, which is displayed in a format imitating a program column of newspaper radio or television. In this electronic program guide, each column is divided by a broadcast channel, a vertical time axis is assigned to each channel, and the program name included in the EPG information is displayed in a frame divided for each time zone. Yes. Further, a frame line highlighted on the cursor 201 for selecting a program is used. In step S602, the cursor 201 is moved to the program frame desired by the user by operating the infrared remote controller 200. When the cursor 201 is moved, the infrared remote controller 200 is generally provided with up / down / left / right four-way movement buttons (not shown), which are used. In step S603, a selection operation is performed by remote control operation. The infrared remote controller 200 has a selection button (not shown) for selection operation, which is used. In step S604, a reservation recording setting confirmation screen is displayed as shown in FIG. 3B.

  The reservation recording setting confirmation screen shown in FIG. 3B includes a recording start year 202, month 203, day 204, and time 205 based on EPG information 114, and recording end year 206, month 207, day 208, and time 209. A channel 210, a recording mode 211, a program name 212, a subtitle 213, a detailed program description 214, a reservation confirmation button 215, and a cancel button 216 are displayed.

Next, in step S605, the setting of the recording mode 211 is changed as desired by the user. In step S606, it is determined whether or not the setting is completed, and these processes are repeated until the setting is completed. The setting can be repeatedly changed by remote control operation until the setting is changed by the processing in steps S605 and S606. Subsequently, in step S607, it is determined whether or not a reservation is set. When setting, if the selection confirmation button 215 is selected in step S608, the EPG information 114 and information necessary for recording reservation are obtained in step S610. The recording reserved program information 112 is stored in the nonvolatile memory 111.

Next, the screen returns to the electronic program guide screen in step S611, and the recording reservation end processing is executed in step S612.
<Processing for scheduled recording execution>
FIG. 7 shows an example of a processing procedure when executing scheduled recording. First, in step S701, based on the current time acquired from the timer 124 built in the HDD recorder 100, a comparison is made with the recording start time of the recording reservation program information 112, and the recording reservation to be executed in step S702 is determined. It is determined whether or not there is. If the result of determination in step S702 is that there is no scheduled recording to be executed, the scheduled recording end processing is executed in step S710 without executing scheduled recording. On the other hand, if there is a recording reservation to be executed as a result of the determination in step S702, the digital broadcast receiving unit 103 selects a channel according to the recording reservation program information to be executed in step S703. In step S704, recording is started in the recording mode specified in the recording reservation program information. Next, in step S705, the program name and subtitle are extracted from the attribute information separated by the attribute information analysis unit 120 from the digital broadcast received during recording. Subsequently, in step S706, the program name and attribute information of the attribute information are extracted. Using the subtitle, the program name and subtitle of the information to be recorded as the recorded program information 116 are replaced from the scheduled recording program information 112. The details of the program name replacement process will be described later.

  Next, it is determined in step S707 whether or not the scheduled recording end time has come. If the end time has not been reached, the recording is continued. If the end time has been reached, the recording is stopped in step S708. In step S 709, information to be recorded in the recorded program information 116 is extracted from the recording reservation program information 112 and recorded in the HDD 105. As described above, the process at the time of executing the scheduled recording is ended.

FIG. 10 shows an example of the data structure of the recorded program information 116 recorded in the HDD 105. The recording start date record start date, which is a component of the data structure struct program info, is obtained by the above-described processing at the time of executing the scheduled recording. Recording start time start time, recording end date record end date, recording end time end time, broadcast station name broadcaster name, program name title, subtitle subtitle, detailed description description, recording mode recording mode, repeated recording reservation setting flag repeat recording flug Is recorded.
<Program name replacement process>
8A, 8B, and 8C are flowcharts showing an example of the program name replacement processing procedure executed in step S706 of FIG. Before using this function, enable the function in advance. A setting screen illustrated in FIG. 9 is used for this setting. In this setting screen, the program name automatic replacement is designated as “valid (on)”, the subtitle is included in the program name as “invalid (off)”, and the subtitle automatic substitution is designated as “valid (on)”. All settings can be set to “invalid (off)” and settings that do not perform the program name replacement process can be specified. Such a setting screen may be specified as a general setting for the entire HDD recorder 100, but can also be set individually for each recording reservation. Therefore, in the present embodiment, description will be made assuming that the user's operation procedure is not limited and the setting function is performed independently.

  First, the processing after step S801 shown in FIG. 8A will be described. In step S801, it is determined whether the program name replacement process is valid. If invalid, the program name of the scheduled recording program information 112 is copied to the recorded program information 116 in step S803. Specifically, the program name title which is a component of the data structure struct program info (hereinafter simply abbreviated as data structure) illustrated in FIG. 10 is the copy destination. At the same time, the program name replaced flag is replaced title is invalidated. When the process of step S803 is completed, the process proceeds to step S820. On the other hand, if the program name replacement process is valid, the program name of the scheduled recording program information 112 is compared with the program name of the attribute information in step S802 to determine whether or not the two are the same. If it is determined that they are the same, the program name of the scheduled recording program information 112 is copied to the recorded program information 116 in step S806, and the program name replaced flag is replaced title is invalidated in step S809. Proceed to the process.

  If it is determined in step S804 that the program names are not the same, the program name of the scheduled recording program information 112 is copied to the recorded program information 116 as an original name in step S807. Specifically, the original program name original title, which is a component of the data structure, becomes the copy destination. In step S808, the program name of the recorded program information 116 is replaced with the program name of the attribute information. Specifically, the program name title which is a component of the data structure is the copy destination. In addition, the program name replaced flag is replaced title is enabled. Next, in step S809, it is determined whether the setting to include a subtitle is valid. If it is not valid, the process proceeds to step S813. If the setting to include a subtitle is valid, it is further determined in step S810 whether or not the attribute information includes a subtitle, that is, whether or not the attribute information subtitle is not blank and includes information. However, if it is determined that it is not included, the process proceeds to step S820. If the information is included, a subtitle of attribute information is added to the program name of the recorded program information 116 in step S811. Specifically, it is added to the character string of the program name title which is a component of the data structure, and the subtitle subtitle is also blank. Next, in step S812, the subtitle of the scheduled recording program information 112 is copied to the recorded program information 116 as an original subtitle. Specifically, the original subtitle which is a component of the data structure is the copy destination. If the subtitle of the recording reservation program information 112 is set as the original subtitle in step S812 and the recorded program information 116 is copied, the program name replacement process ends in step S827.

  Next, the process after step S813 shown to FIG. 8B is demonstrated. In step S813, it is determined whether or not subtitle replacement is enabled. If it is not enabled, that is, if it is disabled, the program replaced flag is replaced title that is a component of the data structure is disabled. Then, the process proceeds to step S820. If subtitle replacement is enabled, it is determined in step S814 whether the attribute information subtitle is not blank and information is included. If information is not included, recording is performed in step S816. The subtitle of the reserved program information 112 is copied to the subtitle of the recorded program information 116. Specifically, the subtitle subtitle that is a component of the data structure is the copy destination. In addition, the subtitle replaced flag is replaced subtitle is invalidated. In step S827, the program name replacement process ends. On the other hand, if the information is included in the subtitle of the attribute information, the subtitle of the attribute information is copied to the program name of the recorded program information 116 in step S815. In addition, the program replaced flag is replaced title which is a component of the data structure is validated. Next, in step S817, it is determined whether or not the original program name of the recorded program information 116 is blank. If it is blank, the program name of the scheduled recording program information 112 is changed to the original program of the recorded program information 116 in step S818. Copy to name. Specifically, the original program name original title, which is a component of the data structure, becomes the copy destination. Thereafter, the process proceeds to step S819. If it is determined in step S817 that the original program name of the recorded program information 116 is not blank, the process proceeds to step S819. In step S819, the subtitle of the recording reservation program information 112 is copied to the recorded program information 116 as the original subtitle. Specifically, the original program name original title, which is a component of the data structure, becomes the copy destination. At the same time, the subtitle of the recorded program information 116 is made blank, and the subtitle replaced flag is replaced subtitle is validated.
