  However, sports broadcast programs such as baseball and soccer may not be finished within the scheduled time, and the broadcast time of the program may be extended. If the broadcast time of the sports relay program is extended, it will be broadcast later. Since the broadcast start time and broadcast end time of the program are delayed, there is a possibility that a desired program broadcast after the sports broadcast program cannot be recorded from the beginning to the end. For example, when an analog broadcast program whose program extension is not reflected in the electronic program guide is set for recording reservation based on the electronic program guide, such a situation is likely to occur.

  Therefore, a user who operates the recording apparatus records a desired program to be broadcast after the sports broadcast program by setting the recording end time of the recording reservation with a delay in consideration of the possibility of extension. However, when a program recorded in this way is played back, there is a problem with workability that searching for the start position of the recorded program, so-called cueing, is troublesome.

  Further, when a recorded program is stored for a long period of time, there is a problem in terms of workability that editing work for deleting recorded contents other than a desired program after the program ends is troublesome for the purpose of saving recording capacity.

  The present invention has been made in view of such circumstances, and when there is a program whose broadcast time may be extended before the program reserved for recording, the recording end time of the program reserved for recording is extended. At the same time, it is possible to record a desired program from the beginning to the end by inserting delimiter information indicating a time delimiter position at the time of recording the program, and to improve workability at the time of editing. The purpose is to provide a device.

  Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof. FIG. 1 is a block diagram illustrating a configuration example of a recording apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes a recording apparatus according to the present invention using a hard disk recorder. A display apparatus 2 such as a CRT display or a liquid crystal display is connected to the recording apparatus 1 through a transmission line for transmitting video signals and audio signals. ing. Further, the recording device 1 is connected to an antenna 3 for receiving a broadcast program transmitted as a broadcast wave such as terrestrial analog broadcast, and infrared rays and the like output from an operation device 4 such as a remote controller operated by a user. The electromagnetic wave for operation is received, and it operates based on the operation signal received as the electromagnetic wave.

  The recording apparatus 1 includes a control unit 101 such as a CPU that controls the entire apparatus, a recording unit 102 such as a ROM that records various information such as programs and data executed under the control of the control unit 101, and control of the control unit 101. And a storage means 103 such as a RAM for temporarily storing data generated when the program is executed. The recording apparatus 1 also includes a recording medium 104 such as a hard disk drive, and recording / reading means 105 that accesses the recording medium 104 to record (record) / read (reproduce) various information.

  The recording device 1 is connected to an antenna 3 and shows a broadcast program of a desired channel from a broadcast wave such as terrestrial analog broadcast received from the antenna 3 and a broadcast schedule including the broadcast time of the program transmitted together with the broadcast program. Further, an acquisition means 106 such as a tuner for acquiring an electronic program guide (hereinafter referred to as EPG information) is provided. In the recording apparatus 1, an analog signal which is a broadcast wave received by the antenna 3 and acquired by the acquisition unit 106 is converted into a digital signal by the A / D conversion unit 107, and a video signal and audio are output from the output unit 108. It outputs to the display apparatus 2 as a signal. However, when the broadcast program acquired by the acquisition unit 106 is a broadcast program to be recorded, the recording apparatus 1 encodes the broadcast program by a predetermined compression encoding method such as MP2 and records it on the recording medium 104. The acquired EPG information is also stored in the storage unit 103 or recorded on the recording medium 104. The recording device 1 does not acquire EPG information by receiving it by the antenna 3, but acquires it by downloading it from an EPG server that is provided on a network (not shown) and stores EPG information. Also good.

  The recording apparatus 1 further includes an operation unit 109 such as a push button that accepts a user operation, and a display unit 110 such as an LED panel that displays various types of information as necessary. Then, when the user performs an input for operating the operation unit 109, the recording apparatus 1 receives an operation using the operation unit 109 and operates based on the received operation. In addition, the recording apparatus 1 includes a light receiving unit 111 that receives electromagnetic waves such as infrared rays. When the user performs an operation to operate the operation apparatus 4, the operation apparatus 4 indicates the content of the operation that has been accepted and accepted. The operation signal is output, and the recording apparatus 1 receives the operation signal by the light receiving unit 111 and operates based on the operation content indicated by the received operation signal.

  The recording apparatus 1 further includes a date management unit 112 having a clock indicating year, month, day, hour, minute, and second, and a reservation management unit 113 that manages recording reservation (timer recording). The means 113 stores the contents of the program recording reservation, and performs program recording processing based on the time management of the date management means 112. The recording reservation managed by the reservation management unit 113 can be performed by the user operating the operation unit 109 or the operation device 4 and inputting the channel of the program to be recorded, the start time, and the end time. It is also possible to use information. Specifically, the program guide based on the EPG information is displayed, and the user operates the operating means 109 or the operating device 4 to specify the program displayed in the program guide, and the program conditions to be reserved for recording. It is performed by a method such as a setting method. The conditions of the program to be reserved for recording are, for example, conditions such as the title (name) of the program, the content, or whether or not the keyword specified for the performer is included, the genre of the program, the broadcast time of the program, and the like.

  Next, various processes of the recording apparatus 1 of the present invention will be described. FIG. 2 is a flowchart showing the recording reservation changing process of the recording apparatus 1 of the present invention. When the recording start time of the reserved program reserved for recording managed by the reservation management unit 113 approaches the recording device 1 under the control of the control unit 101, the recording device 1 updates the EPG information, for example, three minutes before the recording start time. Based on this, it is determined whether there is an extendable program that may extend the broadcasting time in the program broadcast before the reserved program on the same channel as the reserved program related to the recording reservation (S101).

  An extendable program is a program that broadcasts sports such as baseball and soccer whose broadcast time may be extended, for example, and is a program that broadcasts sports live to the title, content, or performer of an EPG program. It is determined whether or not keywords such as a competition name, a team name, a competitor name, and a competition name are included, and if the keyword is included, it is determined that there is a possibility of extension. If a program for live broadcasting of sports can be specified, the determination may be made based on a method other than the keyword, for example, information such as information indicating the genre of the program included in the EPG information. The EPG information includes, for example, a series of programs that are broadcast continuously from a broadcast resumption time such as 5:00 am to a broadcast suspension time such as 3:00 am as a one-day broadcast program. The program broadcast before indicates a program whose broadcast start time is earlier than the broadcast start time of the reserved program on the same day as the reserved program. Note that the same day here is not a day based on the actual date changed at midnight, but a time period during which a series of programs broadcast continuously from the broadcast resumption time to the broadcast suspension time is broadcast. Show. That is, in step S101, it is determined whether there is an extendable program that causes a change in the broadcast time of the reserved program.

  When it is determined in step S101 that there is an extendable program (S101: YES), the recording apparatus 1 extends the recording end time of the reserved program by a predetermined extension time under the control of the control means 101 ( In step S102, the recording reservation is changed to the content in which the recording end time is changed by extending the predetermined time (S103), and the process ends. The predetermined extension time is a time that can be arbitrarily set such as 30 minutes, and is a time managed by the reservation management means 113. For example, when the recording start time of the reserved program is 21:00 and the recording end time is 21:54, the recording end time is changed to 22:24 while keeping the recording start time 21:00.

  If it is determined in S101 that there is no program that can be extended (S101: NO), the processing is terminated without performing the processing after step S102.

  By performing the recording reservation changing process, not only the program that can be extended is automatically determined, but also the user can display the EPG information and manually set the extendable program to the recording apparatus 1. good. In this case, in step S101, it is determined not only whether or not there is an extendable program based on the keyword, but also whether or not the set extendable program exists.

  FIG. 3 is a flowchart showing the recording process of the recording apparatus 1 of the present invention. When the recording apparatus 1 reaches the recording start time of the reserved program whose recording end time has been changed, the recording apparatus 1 starts recording processing of the reserved program. Under the control of the control means 101, the recording apparatus 1 starts recording processing of the reserved program whose recording end time has been changed (S201), and adds delimiter information (chapter) indicating the time delimiter position to the reserved program being recorded. Insert and record (S202).

  As the inserted delimiter information, delimiter information is inserted from the recording start time of the reserved program until a time corresponding to the predetermined extended time is reached for each delimited time set shorter than the predetermined extended time. Specifically, when the recording start time of the reserved program is 21:00 and the predetermined extension time and the segmentation time are set to 30 minutes and 5 minutes, respectively, the times 21:05, 21:10, 21:15 21:20, 21:25 and 21:30, the delimiter information is inserted and recorded. Further, the delimiter information is inserted until the elapsed time from the recording start time corresponds to the time corresponding to the predetermined extension time. In addition, the delimiter information is inserted when the time corresponding to the predetermined extension time is reached from the start of recording, but the time when the time corresponding to the predetermined extension time is reached from the start of recording is 21:30. In this case, since the delimiter information is already inserted at 21:30, it is not necessary to insert delimiter information twice. However, the delimiter information inserted at 21:30 has different attributes from other delimiter information. May be inserted.

  Further, the recording device 1 inserts delimiter information when the recording end time before the extension is reached. Specifically, when the recording end time before the extension is 22:54 and the recording end time is changed to 23:24 by extending the predetermined extension time of 30 minutes, the delimiter information is set at time 22:54. insert. In addition, after reaching the recording end time set before the extension, the separator information is inserted for each separator time set shorter than the predetermined extension time. For example, when the delimiter time is set to 5 minutes, delimiter information is inserted at 22:59, 23:04, 23:09, 23:14, and 23:19.

  By inserting the delimiter information in this way, it is possible to search for the position indicated by the delimiter information, that is, to cue.

  In the above-described embodiment, the predetermined extension time is 30 minutes and the separation time is 5 minutes. However, the present invention is not limited to this, and can be arbitrarily set. Only one of the insertion of the partition information and the insertion of the partition information at the extension time may be performed, or the respective partition times may be set separately.

  Further, in the above-described embodiment, the mode applied when recording an analog broadcast program is shown. However, the present invention is not limited to this, and may be applied when recording digital broadcast such as terrestrial digital broadcast and satellite broadcast. good.

  Furthermore, in the above-described embodiment, the form in which the hard disk recorder is used as the recording device has been described. However, the present invention is not limited to this, and may be applied to other recording devices such as a video tape recorder and a DVD recorder. May be applied to a recording apparatus that records audio such as radio without video, such as a cassette tape recorder or an MD recorder.

It is a block diagram which shows the structural example of the recording device of this invention.
