Description

  The present invention relates to a content reproduction method and a recording / reproduction apparatus capable of performing chasing reproduction by recording broadcast content and reproducing a recorded portion of the content while recording the broadcast content.

2. Description of the Related Art Conventionally, a recording / reproducing apparatus capable of recording broadcast content including video and audio on a recording medium such as a magnetic tape, an optical disk, or a hard disk and reproducing the recorded content at a later date has been widespread. In particular, in a recording / reproducing apparatus using a recording medium such as an optical disk or a hard disk that can be easily accessed at random, on the one hand, the content being broadcast is recorded on the recording medium, and on the other hand, the same content data is read from the recording medium and the content is reproduced. By doing so, some have a chasing playback function that allows the viewer to view the content at different times. At the time of chasing playback, the recording / playback apparatus can play back the content by fast-forwarding so that the portion of the content being viewed by the user catches up with the portion being broadcast. Such a chasing reproduction technique is disclosed in, for example, Japanese Patent Application Laid-Open No. H10-228707.
JP 2004-158153 A

  In the chasing playback process, in order for the part of the content viewed by the viewer to catch up with the part being broadcast, the recording / playback apparatus needs to play back the content at a speed of 1 × or higher, usually 1.5 × speed. Alternatively, the content is reproduced at a predetermined speed such as double speed. However, as the playback speed of the content increases, there is a problem that the playback quality of video and audio included in the content deteriorates. In order to suppress the deterioration of the playback quality, the playback speed should be as close to 1 × as possible. desirable.

The present invention has been made in view of such circumstances, and the purpose of the present invention is to ensure that the playback portion of the content can reliably catch up with the portion being broadcast when performing the follow-up playback of the content. obtains the playback speed, by playing the content at a reproduction speed obtained is to provide a can be ∎ you can record reproducing apparatus possible to suppress the deterioration of the reproduction quality of the content.

A recording / reproducing apparatus according to the present invention comprises: a recording unit that records content being broadcast; and a reproducing unit that reproduces an already recorded portion of the content being recorded by the recording unit. The means for storing the broadcast date and time of the content, the means for receiving an instruction to reproduce the content being recorded, and the instruction to reproduce the content being recorded based on the broadcast date and time of the stored content Means for obtaining a time T1 from the time when the reproduction instruction is received to the time when the broadcast of the content being recorded is ended, and the part of the content after the part where the reproduction means starts reproduction when the reproduction instruction is received from time obtained by adding the time T1 to the recording time T2 value of time obtained by subtracting the advertising occupied time T3 in the recording time Means for calculating a quotient obtained by dividing the value of the time T1, at a rate equal correct magnification to the quotient said means has calculated, to the reproduction means, said recording means recording at the time of receiving the reproduction instruction Means for skipping an advertisement contained in the content portion being played and reproducing the content.

In the present invention, the recording / reproducing apparatus subtracts the time T3 occupied by the portion of the advertisement that has already been recorded at the time of starting reproduction from the time T2 required for reproducing the content at 1 × speed when performing the follow-up reproduction. A playback speed with a magnification equal to the division value obtained by dividing the time value by the time T1 until the end of broadcasting is obtained, the already recorded advertisement part is skipped, and the content is played back at the obtained playback speed. By determining the playback speed in this way, the playback of the content ends almost at the same time as the broadcast of the content ends, and the portion of the advertisement that has already been recorded when the playback of the content starts. Since the excluded content is played back within the time T1, the playback speed of the content is slower than when playing back the content including the advertisement.

A recording / reproducing apparatus according to the present invention comprises: a recording unit that records content being broadcast; and a reproducing unit that reproduces an already recorded portion of the content being recorded by the recording unit. The means for storing the broadcast date and time of the content, the means for accepting the reproduction instruction for the content being recorded, and the time from the current broadcast of the content being recorded to the end based on the broadcast date and time of the stored content A time calculating means for calculating a time T1 , and a time T2 obtained by adding the time T1 calculated by the time calculating means to a recording time of an unreproduced portion of the content portion recorded by the recording means. A division means for calculating a division value obtained by dividing a time value obtained by subtracting the time T3 occupied by the advertisement by the value of the time T1, and the division means At a rate equal correct magnification to the divided value, to said reproduction means, a chasing reproduction means to reproduce the content of a predetermined amount while skipping the advertisement, after playing the content of a predetermined amount, the time calculating means, said And a means for repeating the operations of the division means and the chasing reproduction means.

  In the present invention, the recording / playback apparatus performs the follow-up playback by subtracting the time T3 of the recorded advertisement from the time T2 required for playback of the content at 1 × speed as the time T1 until the end of broadcasting. A playback speed having a magnification equal to the divided value obtained by dividing is obtained, and the playback speed is repeatedly calculated as the recording of the content progresses, and the content is played back at the playback speed calculated each time while skipping advertisements. As the recording of the content is progressed, the playback speed is recalculated so that the content excluding the portion of the advertisement that is sequentially recorded can be played back within the time T1, so that the playback speed of the content is gradually reduced. The playback speed is slower than when the content excluding the recorded portion of the advertisement is played.

  In the present invention, in performing the follow-up reproduction, the content reproduction speed is determined so that the content reproduction ends almost at the same time as the content broadcast ends. Therefore, the content reproduction surely catches up with the content broadcast. be able to. In addition, since the content reproduction speed is not increased more than necessary, it is possible to suppress deterioration in the reproduction quality of the content during the follow-up reproduction.

  Further, in the present invention, in chasing playback, the content excluding the portion of the advertisement that has already been recorded at the time of starting playback of the content is played within the time until the end of the broadcast. In addition to ensuring that the content playback can catch up with the content broadcast at the time of playback, the content playback speed is slower than when playing content that contains advertisements. Deterioration of reproduction quality can be further suppressed.

  Further, according to the present invention, when chasing playback is performed, the playback speed is sequentially calculated so that the content excluding the portion of the advertisement that is sequentially recorded as the recording of the content can be played within the time until the end of the broadcast. Therefore, the playback speed of the content is gradually reduced, and the playback speed is slower than that in the case of playing the content excluding the portion of the advertisement recorded at the start of playback. Therefore, in addition to ensuring that the content playback can catch up with the content broadcast when the follow-up playback is executed, the content playback speed is higher than when the content is removed except for the portion of the advertisement recorded at the start of playback. Since it becomes slower, it is possible to surely prevent deterioration in the reproduction quality of the content when the chasing reproduction is executed. In addition, the present invention has an excellent effect such that the user can watch the content that does not contain an advertisement by chasing playback.

Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof.
FIG. 1 is a block diagram showing the internal configuration of the recording / reproducing apparatus 1 of the present invention. The recording / reproducing apparatus 1 of the present invention is connected to a television receiver 2 and is configured to perform processing for reproducing content using the television receiver 2. The recording / reproducing apparatus 1 includes a control unit 11 that controls the operation of the entire recording / reproducing apparatus 1. Connected to the control unit 11 are a RAM 12 that stores information necessary when the recording / reproducing apparatus 1 executes various processes, and a ROM 13 that stores a control program for the control unit 11 to control the recording / reproducing apparatus 1. Has been. The control unit 11 is connected to a remote control receiving unit 14 that receives a signal transmitted from a remote controller (remote control) 3 operated by a user.

  The control unit 11 is connected to a signal processing unit 15 that processes and transmits video signals and audio signals. The control unit 11 and the signal processing unit 15 are connected to a tuner unit 17 for receiving various broadcasts such as terrestrial broadcast, satellite broadcast, cable broadcast, analog broadcast, and digital broadcast. The tuner unit 17 is connected to an external antenna or communication line (not shown), and receives various broadcast signals via the antenna or communication line, thereby receiving the broadcast content. The signal processing unit 15 performs signal processing such as decoding the broadcast signal received by the tuner unit 17 and converting it into a video signal and an audio signal. The tuner unit 17 can receive electronic program guide (EPG) data in addition to the broadcast signal corresponding to the program, and the recording / reproducing apparatus 1 uses the EPG data that has received various processes such as program selection. It is the composition which can be executed.

  The control unit 11 and the signal processing unit 15 are connected to a recording unit (recording unit) 18 for recording and reading data on a randomly accessible recording medium such as a hard disk, an optical disk, or a semiconductor memory. The recording unit 18 may have a form in which a recording medium is built in, or may have a form in which data is recorded and read by receiving a removable recording medium. The signal processing unit 15 processes the broadcast signal received by the tuner unit 17 and encodes it for recording, and the control unit 11 broadcasts the data encoded by the signal processing unit 15 in the recording unit 18. The content is recorded in the recording unit 18.

  The signal processing unit 15 is connected to an output unit 16 that outputs a video signal and an audio signal to the outside. The output unit 16 is configured to be connectable to the television receiver 2 using a cathode ray tube display or a liquid crystal display. The signal processing unit 15 processes the broadcast signal received by the tuner unit 17 or the data read by the recording unit 18, and the output unit 16 converts the video signal and the audio signal processed by the signal processing unit 15 into a television receiver. Output to 2. The television receiver 2 displays video and outputs audio based on the video signal and audio signal from the recording / reproducing apparatus 1. In this way, the control unit 11, the recording unit 18, the signal processing unit 15, and the output unit 16 function as reproducing means according to the present invention.

Next, the content playback method of the present invention executed by the recording / playback apparatus 1 having the above configuration will be described. The recording / reproducing apparatus 1 receives the broadcast content by receiving the broadcast signal at the tuner unit 17, and reads the content data from the recording unit 18 while recording the received content data at the recording unit 18. Chasing playback can be executed. In chasing playback, playback is performed at a playback speed faster than 1x so that the playback part catches up with the broadcast. In the content playback method of the present invention, the playback speed is calculated according to the content, and the content is played at the calculated playback speed. Perform the playback process.

  FIG. 2 is a flowchart showing a procedure of processing in which the recording / reproducing apparatus 1 of the present invention performs the follow-up reproduction after calculating the reproduction speed. The control unit 11 of the recording / reproducing apparatus 1 executes the following processing according to the control program recorded in the ROM 13. The remote controller receiving unit 14 receives a processing signal from the remote controller 3 operated by the user, and the recording / reproducing apparatus 1 accepts a program designation or records content using the EPG data received by the tuner unit 17. By accepting designation of a channel and date / time to be received, a recording reservation for content is accepted. The control unit 11 stores the received reservation information in the RAM 12 and performs a process of waiting for the date and time to start recording the content. The control unit 11 causes the tuner unit 17 to receive the broadcast signal of the content specified by the reservation when the date and time when the content recording should start is received, and processes the received broadcast signal in the signal processing unit 15 for recording. The content data processed for recording is recorded in the recording unit 18 and the content being broadcast is recorded (S11).

  Next, the control unit 11 waits for the remote control receiving unit 14 to accept an instruction to reproduce the content being recorded by operating the remote control 3 by the user (S12). When the content reproduction instruction is not received (S12: NO), the control unit 11 continues to wait for reception of the content reproduction instruction while recording the content. When receiving an instruction to reproduce the content being recorded (S12: YES), the control unit 11 compares the reserved recording end date and time with the current date or time, or refers to the broadcast date and time of the content indicated by the EPG data. The time T1 from the time when reproduction is started to the time when broadcasting of the content being recorded ends is calculated by a method such as (S13). Next, the control unit 11 calculates a time T2 obtained by adding the recording time of the part to be reproduced among the parts recorded by the content recording unit 18 and the time T1 (S14). This time T2 is T2 = Tr + T1, where Tr is the recording time of the portion to be played back of the already recorded content, and is the time required for playback when the recording / playback apparatus 1 plays back the content at 1 × speed. . Note that a process of calculating T2 by further adding or subtracting a predetermined amount to Tr + T1 may be performed. Next, the control unit 11 calculates a division value obtained by dividing the value of the time T2 by the value of the time T1, and sets the reproduction speed of the content compared to the 1 × speed to a speed substantially equal to the calculated division value. As a result, the playback speed of the content is calculated (S15). That is, the reproduction speed is (T2 / T1) times faster.

  Next, the control unit 11 causes the recording unit 18 to read the content data, causes the signal processing unit 15 to process the data so that the content can be played back at the calculated playback speed, and processes the data as a video signal and an audio signal. Is output to the television receiver 2 by the output unit 16 to perform processing for reproducing the content at the calculated reproduction speed (S16). The television receiver 2 outputs the content at the reproduction speed calculated by the recording / reproducing apparatus 1 based on the video signal and the audio signal from the recording / reproducing apparatus 1.

  Next, the control unit 11 ends the reproduction of the content when the user operates the remote control 3 to accept an instruction to end the reproduction of the content by the remote control reception unit 14 or when the broadcast of the content being recorded ends. Wait for the opportunity (S17). When there is no opportunity to end the reproduction of the content (S17: NO), the control unit 11 continues the process of reproducing the content at the calculated reproduction speed while recording the content. When the opportunity to finish playing the content comes (S17: YES), the control unit 11 finishes the process of playing the content.

  As described in detail above, the recording / reproducing apparatus 1 of the present invention performs the follow-up reproduction of reproducing the already recorded portion while recording the content being broadcast, and the portion of the content to be reproduced is set to a single speed to the end of the broadcast. The content is reproduced at a speed equal to the division value obtained by dividing the value of the time T2 required for reproduction by the value of the time T1 from the start of reproduction to the end of broadcasting. By determining the playback speed by such a method, the playback of the content ends almost at the same time as the broadcast of the content ends. Accordingly, when the follow-up reproduction is executed, the content reproduction can surely catch up with the content broadcast. In addition, since the playback speed is not increased more than necessary, it is possible to suppress the deterioration of the playback quality of the content when the follow-up playback is executed.

  By the way, the broadcasted content generally includes an advertisement (CM) composed of predetermined video and audio. The recording / reproducing apparatus 1 of the present invention is configured to be able to reproduce a content while skipping a CM portion included in the recorded content. FIG. 3 is a flowchart showing a procedure of processing in which the recording / reproducing apparatus 1 of the present invention skips a CM and performs follow-up reproduction. The control unit 11 of the recording / reproducing apparatus 1 executes the following processing according to the control program recorded in the ROM 13. The control unit 11 causes the tuner unit 17 to receive the broadcast signal of the content specified by the reservation when the date and time when the content recording should start is received, and processes the received broadcast signal in the signal processing unit 15 for recording. The content data processed for recording is recorded in the recording unit 18 to record the content being broadcast (S21). Next, the control unit 11 waits for the remote control receiving unit 14 to receive an instruction to play back the content being recorded by operating the remote control 3 by the user (S22). When the content reproduction instruction is not received (S22: NO), the control unit 11 continues to wait for reception of the content reproduction instruction while recording the content. When an instruction to reproduce the content being recorded is received (S22: YES), the control unit 11 finishes broadcasting the content being recorded from the time when reproduction is started based on the reservation information stored in the RAM 12. The time T1 until the point of time is calculated (S23). Next, the control unit 11 calculates a time T2, which is a time obtained by adding the recording time of the part to be reproduced among the parts recorded by the content recording unit 18 and the time T1 (S24).

  Next, the control unit 11 specifies the part where the CM is recorded in the part to be reproduced of the content recorded by the recording unit 18, and the CM within the recording time of the part to be reproduced of the content. The time T3 occupied by the portion is obtained (S25). Here, the control unit 11 specifies a stereo audio CM part from the monaural audio content, or specifies a monolingual CM part from the bilingual content. Based on the type difference, the CM portion is specified from the content. Further, the recording / reproducing apparatus 1 may be configured to record information indicating the CM portion at the same time when the content is recorded, and to perform processing for specifying the CM portion by referring to the recorded information.

  Next, the control unit 11 calculates a subtraction time obtained by subtracting the time T3 obtained in step S25 from the time T2 (S26), and then calculates a division value obtained by dividing the calculated subtraction time value by the time T1 value. The content playback speed is calculated by calculating and setting the playback speed at a magnification substantially equal to the calculated division value (S27). That is, the reproduction speed is {(T2-T3) / T1} times faster. Next, the control unit 11 causes the recording unit 18 to read out the content data, causes the signal processing unit 15 to exclude the CM portion recorded at the time of playback start from the data, and further at the calculated playback speed. The data is processed so that the content can be reproduced, and the video signal and the audio signal which have been processed are output to the output unit 16 to the television receiver 2, thereby skipping the already recorded CM portion and calculating. Processing for reproducing the content at the reproduction speed is performed (S28). Next, the control unit 11 waits for an opportunity to end the reproduction of the content, such as when the remote control receiving unit 14 receives an instruction to end the reproduction of the content, or the broadcast of the content being recorded ends (S29). If there is no opportunity to finish playing the content (S29: NO), the control unit 11 continues the process of playing the content at the calculated playback speed while recording the content. If the opportunity to finish playing the content comes (S29: YES), the control unit 11 finishes the process of playing the content.

  In the above processing, the recording / reproducing apparatus 1 of the present invention subtracts the time T3 occupied by the CM portion included in the content already recorded at the time of starting the reproduction from the time T2 when performing the follow-up reproduction. The reproduction speed equal to the division value obtained by dividing the value of T by the value of time T1 is obtained, the already recorded CM portion is skipped, and the content is reproduced at the obtained reproduction speed. Since the content excluding the CM portion already recorded at the time of starting the content reproduction is reproduced within the time until the end of the broadcast, the content reproduction is performed compared to the case of reproducing the content including the CM. The speed is slower. Therefore, the content playback can surely catch up with the content broadcast when the follow-up playback is executed, and the playback speed of the content is slower than when the content including the CM is played back. Sometimes, it is possible to further suppress deterioration in the reproduction quality of content.

  In the above processing, the processing for calculating the playback speed of the content excluding the CM portion recorded at the time of starting playback of the content has been shown. However, in this processing, recording is still performed at the time of starting playback of the content. It is not possible to calculate the playback speed excluding the CM portion included in the content portion that has not been processed. The recording / reproducing apparatus 1 of the present invention is configured to be able to perform processing for recalculating the reproduction speed of content each time recording of the content proceeds. FIG. 4 is a flowchart showing a procedure of processing in which the recording / reproducing apparatus 1 of the present invention performs chasing reproduction while skipping CMs by repeating recalculation of the reproduction speed. The control unit 11 of the recording / reproducing apparatus 1 executes the following processing according to the control program recorded in the ROM 13. The control unit 11 causes the tuner unit 17 to receive the broadcast signal of the content specified by the reservation when the date and time when the content recording should start is received, and processes the received broadcast signal in the signal processing unit 15 for recording. Then, the content data processed for recording is recorded in the recording unit 18, and the content being broadcast is recorded (S301).

  Next, the control unit 11 waits for the remote control receiving unit 14 to accept an instruction to play back the content being recorded by the user operating the remote control 3 (S302). When the content reproduction instruction is not received (S302: NO), the control unit 11 continues to wait for reception of the content reproduction instruction while recording the content. When the instruction to reproduce the content being recorded is received (S302: YES), the control unit 11 starts from the current time until the end of the broadcast of the content being recorded based on the reservation information stored in the RAM 12. Time T1 is calculated (S303). In this way, the control unit 11 functions as time calculation means according to the present invention. Next, the control unit 11 calculates a time T2 obtained by adding the recording time of the part to be reproduced and the time T1 among the parts recorded by the content recording unit 18 (S304).

  Next, the control unit 11 specifies a portion where the CM is recorded in the portion of the content recorded by the recording unit 18 and is to be reproduced from now, and within the recording time of the portion of the content to be reproduced from now on. The time T3 occupied by the CM part is obtained (S305). Next, the control unit 11 calculates a subtraction time obtained by subtracting the time T3 obtained in step S305 from the time T2 (S306), and calculates a division value obtained by dividing the calculated subtraction time value by the time T1 value. The playback speed of the content is calculated by setting the playback speed at a magnification substantially equal to the calculated division value (S307). In this way, the control unit 11 functions as a dividing unit according to the present invention. Next, the control unit 11 causes the recording unit 18 to read the content data, causes the signal processing unit 15 to exclude the CM portion from the data, and further processes the data so that the content can be played back at the calculated playback speed. Then, by causing the output unit 16 to output the video signal and the audio signal processed data to the television receiver 2, the content is reproduced at the calculated reproduction speed while skipping the CM portion (S308). . In this way, the control unit 11 functions as a chase reproducing unit according to the present invention.

  Next, the control unit 11 determines whether or not a predetermined amount of reproduction has been performed based on whether a predetermined time has elapsed while reproducing the content or a predetermined recording time of the content has been reproduced (S309). ). If the predetermined amount of reproduction has not been performed (S309: NO), the process of reproducing the content at the calculated reproduction speed is continued while recording the content. When a predetermined amount of reproduction has been performed (S309: YES), the control unit 11 then receives an instruction to end the reproduction of the content by the remote control reception unit 14, or the content by the end of the broadcast of the content being recorded, etc. Is waited for an opportunity to end playback (S310). When there is no opportunity to end the reproduction of the content (S310: NO), the control unit 11 returns the process to step S303, and from the content including the portion newly recorded as the recording of the content proceeds, the CM portion is extracted. The processing for reproducing the content while skipping the CM is newly calculated by newly calculating the reproduction speed for reproducing the content excluding the content. When the opportunity to finish playing the content comes (S310: YES), the control unit 11 finishes the process of playing the content.

  In the above processing, the recording / reproducing apparatus 1 of the present invention performs the follow-up reproduction by subtracting the time T3 of the CM included in the recorded content to be reproduced from the time T2 as the value of the time T1. A playback speed with a magnification equal to the divided value obtained by dividing is obtained, and the playback speed calculation is repeated as the recording of the content progresses, and the content is played back at the calculated playback speed each time while skipping CMs. As the content recording progresses, the content playback speed is gradually recalculated so that the content excluding the CM portion that is sequentially recorded can be reproduced within the time until the end of the broadcast. The playback speed is slower than that in the case of playing content excluding the CM portion recorded at the start of playback. Therefore, in addition to the fact that the content reproduction can reliably catch up with the content broadcast when the follow-up reproduction is executed, the content reproduction speed is higher than that in the case of reproducing the content excluding the CM portion recorded at the start of the reproduction. Since it becomes slower, it is possible to surely prevent deterioration in the reproduction quality of the content when the chasing reproduction is executed. In addition, by using the recording / reproducing apparatus 1 of the present invention, a user can watch content that does not include a CM by chasing playback.

  The recording / reproducing apparatus 1 of the present invention can change which of the three types of processing described above for calculating the reproduction speed is to be executed by setting. Further, the recording / reproducing apparatus 1 may be configured to execute any one or two processes.
