The best mode for carrying out the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is a diagram illustrating a configuration of a recording apparatus 100 according to the present embodiment. As shown in FIG. 1, the recording apparatus includes an antenna 101, a tuner 102, a demodulation unit 103, a recording unit 104, an AV decoder 105, an output unit 106, a remote control light receiving unit 107, a CPU 108, and a recording medium receiving unit 109. Further, the user can control the operation of the recording apparatus 100 using the remote controller 200.

  The antenna 101 receives radio waves for broadcasting in which a plurality of channels are mixed. The tuner 102 selects a specific channel designated by the CPU 108 from the broadcast radio wave, and outputs only the signal of the designated specific channel.

  The demodulation unit 103 performs OFDM demodulation on the received signal of the specific channel based on an instruction from the CPU 108, and outputs 12-segment and 1-segment MPEG-TS.

  The recording unit 104 records 12-segment and 1-segment MPEG-TS data according to an instruction from the CPU 108. During reproduction, the MPEG-TS data recorded in the recording unit 104 is read out. The recording unit 104 corresponds to, for example, a hard disk.

  The AV decoder 105 decodes the input 12-segment and 1-segment MPEG-TS in response to an instruction from the CPU 108, and outputs video data and audio data as digital data. The output unit 106 converts the input video and audio digital data into a predetermined format and outputs it. The output unit 106 corresponds to, for example, an HDMI terminal.

  The remote controller 200 is operated by the user and outputs a remote control signal. The remote control light receiving unit 107 receives a remote control signal output from the remote control 200 and outputs it as a remote control code for device operation.

  The CPU 108 controls the recording apparatus 100 such as a channel selection operation, a demodulation operation, a recording / reproducing operation, an AV decoding operation, and a recording operation on a recording medium according to the analysis of the remote control code output from the remote control light receiving unit 107 and each user operation.

The storage medium received by the recording medium receiving unit 109 may be a disk-type storage medium represented by a DVD disk or a Blu-ray disk, or a card-type recording medium represented by an SD card.

  When a dubbing request from the user is received, the 1-segment MPEG-TS recorded in the recording unit 104 is dubbed to the recording medium inserted in the recording medium receiving unit 109.

  FIG. 2 is a diagram schematically showing that the broadcast contents at the same time are shifted from each other in a broadcast program assigned 12 segments and a broadcast program assigned 1 segment in terrestrial digital broadcasting. .

  The 12-segment broadcast portion at the top of FIG. 2 is the 12-segment broadcast main section that broadcasts the main section of the 12-segment broadcast program as time elapses on the horizontal axis (t), and the 12-segment broadcast that broadcasts commercials (CM) This indicates that the CM section has been switched.

  The lower 1-segment broadcasting part of FIG. 2 shows the 1-segment broadcasting main section that broadcasts the main section of the 1-segment broadcasting program with the passage of time on the horizontal axis (t), and the 1-segment broadcasting that broadcasts commercials (CM). This indicates that the CM section is switched. Thus, even when the same content is broadcast at the same time, the 1-segment broadcast is broadcast with a delay compared to the 12-segment broadcast.

  FIG. 3 is a flowchart for calculating a deviation amount (ΔT) between a program broadcast in 12 segments and a program broadcast in 1 segment. First, in the recording apparatus 100, during recording of the 12-segment broadcast program and the 1-segment broadcast program that have received a specific channel, the CPU 108 detects the switching time from the main part to the CM of each 12-segment broadcast program and 1-segment broadcast program. (S10).

  Next, the switching times of the detected 12-segment broadcast and 1-segment broadcast from the main part to the CM are compared (S20).

  From the comparison result of the switching time from the main part of each broadcast to the CM, the amount of deviation (ΔT) between the start time of the program broadcast in 12 segments and the program broadcast in 1 segment is calculated (S30).

  FIG. 4 is a flowchart when dubbing one-segment recorded content recorded in the recording unit 104 to a recording medium recorded in the recording medium receiving unit 109.

  First, by a user operation, a dubbing execution instruction to a recording medium inserted into the recording medium receiving unit 109 with a specific one-segment recording content recorded in the recording unit 104 is received (T10).

  When the remote control light receiving unit 107 accepts a dubbing execution instruction, the CPU 108 dubs the one-segment recorded content instructed by the user recorded in the recording unit 104 to the recording medium inserted in the recording medium accepting unit 109 (T20). .

  Next, the CPU 108 determines whether or not the reproduction interruption position information (resume point) is set in the same 12-segment recorded content as the 1-segment recorded content designated as the dubbing target (T30).

  When set, the CPU 108 corrects the deviation amount by adding the deviation amount (ΔT) detected in the operation shown in FIG. 3 to the resume point of the 12-segment recorded content. The CPU 108 writes the dubbed 1-segment recorded content as a resume point on the recording medium (T40).

  FIG. 5 is a diagram for explaining the addition of the shift amount (ΔT) described in FIG. FIG. 5 shows the chapter information set in the 12-segment recorded content of the same broadcast as the dubbing source recorded in the recording unit 104 when the 1-segment recorded content is dubbed to the recording medium inserted in the recording medium receiving unit 109. Is transferred to the 1-segment recorded content.

  The 12-segment recorded content in the upper part of FIG. 5 is the recording length (t) of the recorded content on the horizontal axis, and chapter A is set at the tA position of the 12-segment recorded content recorded in the recording unit 104. It shows that chapter B is set.

  The 1-segment recorded content at the bottom of FIG. 5 is the recording length (t) of the recorded content on the horizontal axis, and the 12-segment recording is performed after the 1-segment recorded content is dubbed to the recording medium inserted in the recording medium receiving unit 109. This indicates that chapter A and chapter B information set in the content is written to the recording medium as chapter C and chapter D, respectively, in the 1-segment recording content of the dubbing destination.

  At this time, the amount of deviation of the broadcast program is corrected by adding the amount of deviation (ΔT) detected in FIG. 3, and the chapter positions are written on the recording medium as chapter C = tA + ΔT and chapter D = tB + ΔT.

  That is, the recording apparatus 100 according to the present embodiment receives a 12-segment broadcast program and a 1-segment broadcast program that is broadcast on the same channel as the 12-segment broadcast program and has the same content with a different encoding method, and can record simultaneously. In the case where the 1-segment broadcast program is broadcast with a delay relative to the 12-segment broadcast program, and the chapter information is added to the 12-segment broadcast program and stored in the recording device 100, The recording apparatus 100 includes an antenna 101 and a tuner 102 that can receive a 12-segment broadcast program and a 1-segment broadcast program, a remote control light receiving unit 107 that receives a user instruction, and a 12-segment broadcast program received by the antenna 101 and the tuner 102.

CPU 108 that writes the calculated chapter information together with a 1-segment broadcast program.

  In addition, the recording apparatus 100 according to the present embodiment includes a CPU 108 that detects a commercial broadcast period of a 12-segment broadcast program, and a CPU 108 that detects a commercial broadcast period of a 1-segment broadcast program. Based on the commercial broadcast period of the broadcast program and the commercial broadcast period of the 1-segment broadcast program detected by the CPU 108, the delay amount of the 1-segment broadcast program with respect to the 12-segment broadcast program is calculated.

  Further, in the recording apparatus 100 of the present embodiment, the chapter information is resume information indicating the time when the program being reproduced is stopped.

  Further, in the recording apparatus 100 of the present embodiment, the chapter information is chapter information for a 12-segment broadcast program received by the remote control light receiving unit 107 by the user.

  Thereby, even when the chapter information given to the 12-segment recorded content is dubbed to the 1-segment recorded content, the amount of deviation between the 12-segment recorded content and the 1-segment recorded content is corrected and the chapter information is dubbed. . Accordingly, it is possible to eliminate the gap between chapter information of 12-segment recorded content and 1-segment recorded content.

  If the 12-segment recorded content recorded in the recording unit 104 has an erasure period, even if the corresponding 1-segment recorded content is recorded, the erase period may be recorded as 1-segment recorded content as chapter information. good. In this case, more accurate chapter information can be given by correcting the amount of deviation between the 12-segment recorded content and the 1-segment recorded content.

  FIG. 6 shows that when a 1-segment recorded content is dubbed to the recording medium inserted in the recording medium accepting unit 109, the 12-segment recorded content of the same broadcast as the dubbing source recorded in the recording unit 104 has a partial erasure section. It shows that the erasure start point and end point are taken over as chapter information in the 1-segment recorded content.

  In the upper 12-segment recorded content in FIG. 6, the horizontal axis represents the recorded content recording length (t), and the 12-segment recorded content recorded in the recording unit 104 is partially erased from the tA position to the tB position. Show.

  The 1-segment recorded content in the lower part of FIG. 6 is the recording length (t) of the recorded content on the horizontal axis, and the 12-segment recording is performed after the 1-segment recorded content is dubbed to the recording medium inserted in the recording medium receiving unit 109. The section information from the erasure start point A to the erasure end point B set in the content is written to the recording medium as chapter C and chapter D, respectively, in the dubbing destination 1-segment recording content.

  At this time, the amount of deviation (ΔT) detected in FIG. 3 is added to correct the amount of deviation, and the chapter positions are written on the recording medium as chapter C = tA + ΔT and chapter D = tB + ΔT.

  That is, in the recording apparatus 100 of the present embodiment, when a 1-segment broadcast program is dubbed by the CPU 108, when a part of the 12-segment broadcast program corresponding to the 1-segment broadcast program is deleted, In the case where information regarding the start time and end time of the erased period is added to a 1-segment broadcast program as chapter information, the provided chapter information is delayed based on the delay amount.

  Thereby, the chapter information regarding the erase period of the 12-segment recorded content can be given with high accuracy.

  Also, due to the difference between the 12-segment broadcast and the 1-segment broadcast, when recording the content, the time to end the recording of the content differs. Therefore, the recording end time may be changed based on the amount of deviation between 12-segment broadcasting and 1-segment broadcasting.

FIG. 7 is a diagram showing from the start of recording to the stop of recording of 12-segment broadcasting and 1-segment broadcasting. The upper 12-segment recorded content in FIG. 7 is the recorded length (t) of the recorded content on the horizontal axis.
The progress from recording start to recording stop is shown. In the 1-segment recorded content at the bottom of FIG. 6, the horizontal axis indicates the recording length (t) of the recorded content, and shows the progress from the recording start to the recording stop.

  According to FIG. 7, when stopping the recording of 12-segment broadcasting and 1-segment broadcasting that are simultaneously recorded, the recording of 12-segment broadcasting is stopped, and after the amount of deviation (ΔT) detected in FIG. This indicates that the recording of the broadcast has been stopped.

That is, the recording apparatus 100 according to the present embodiment receives and records simultaneously a 12-segment broadcast program and a 1-segment broadcast program that is broadcast on the same channel as the 12-segment broadcast program and has the same content with a different encoding method.
