Description

  The present invention relates to a recording / playback apparatus having a CM skip function.

  In recent years, with the increase in the number of channels by digital broadcasting and the appearance of a long-time recording apparatus using a large-capacity hard disk, time-shifted viewing for viewing at an arbitrary time after recording is increasing. However, in time-shifted viewing, special playback such as fast-forwarding and skipping can be easily performed, so the user often skips the CM for viewing. In this case, it is difficult for an advertiser who is a sponsor of the broadcasting station to obtain an effect commensurate with the advertising cost.

In a conventional recording / playback apparatus, CM data for playback is separately received and stored, and playback data is controlled at an arbitrary timing to reliably display advertisement data (for example, described in Patent Document 1). However, this method is based on the premise that functions such as fast-forward and skip cannot be used when playing advertisement data, which causes discomfort to the user who wants to watch the CM by skipping the CM, and conversely gives the advertiser a negative impression. May give.

  When the user tries to skip the CM for the recorded broadcast program, if the CM is completely skipped, the sponsor cannot obtain the advertising effect. On the other hand, if the skip is completely prohibited, the user is uncomfortable.

  It is an object of the present invention to provide a recording / playback apparatus that maintains a certain advertising effect and does not cause discomfort to the user.

  A recording / playback apparatus according to the present invention includes a broadcast data receiving unit that receives a broadcast program, a broadcast data storage unit that stores the broadcast program, and broadcast data that causes the broadcast data storage unit to record the broadcast program received by the broadcast data reception unit. A recording unit, a reproduction data extraction unit for extracting a broadcast program recorded in the broadcast data recording unit, a reproduction data reproduction unit for decoding the broadcast program extracted by the reproduction data extraction unit, and the decoded broadcast program being included in the program A CM monitoring unit that determines whether or not a CM is in progress, a skip request detection unit that detects pressing of the fast-forward key, and a CM monitoring unit that determines that the CM is in progress, and the skip request detection unit presses the fast-forward key. If it is detected, the reproduction data reproduction unit includes a CM data control unit that controls to reproduce the shortened CM data. When a user tries to skip a CM for a recorded broadcast program, the CM is skipped, and by playing a shortened version of the CM, the sponsor can see more of the video when fast-forwarding. A high advertisement effect can be expected, and the CM can be skipped without fail when trying to skip the CM by fast-forwarding.

  The recording / playback apparatus according to the present invention shows a short advertisement data instead of showing the user a clip of fast-forwarding when a user uses a function such as fast-forwarding to skip the CM. Therefore, a higher advertising effect can be expected without causing discomfort to the user. Also, for the user, when skipping the CM by fast-forwarding, the CM can be surely skipped without excessively fast-forwarding, so that the user can also view comfortably.

(Embodiment 1)
FIG. 1 is a block diagram showing a configuration of a recording / playback apparatus according to Embodiment 1 of the present invention. The recording / playback apparatus according to the present embodiment includes a broadcast data receiving unit 101, a broadcast data recording unit 102, a broadcast data storage unit 103, a playback data extraction unit 104, a playback data playback unit 105, and a CM monitoring unit 106. A skip request detection unit 107, a CM data control unit 108, and a reproduction data display unit 109.

  The broadcast data receiving unit 101 receives a broadcast program such as digital broadcast. The broadcast data recording unit 102 transmits the received broadcast program to the broadcast data storage unit 103 described later. The broadcast data storage unit 103 stores received broadcast programs. The reproduction data extraction unit 104 extracts a broadcast program to be reproduced from the broadcast data storage unit 103. The reproduction data reproduction unit 105 decodes the broadcast program extracted by the reproduction data extraction unit 104 based on a CM data control unit 108 described later. The CM monitoring unit 106 determines whether the broadcast program being reproduced is a program or a CM. The skip request detection unit 107 detects that the user has pressed the fast forward key. When the skip request detection unit 107 detects the skip request from the user and the CM monitoring unit 106 determines that the CM is in the CM, the CM data control unit 108 sends the shortened CM data to the playback data playback unit 105. Control to extract and play. The reproduction data display unit 109 displays the broadcast program decoded by the reproduction data reproduction unit 105.

  FIG. 2 is a diagram showing a broadcast data configuration in Embodiment 1 of the present invention. In the CM of the broadcast data 201, CM information 202 is periodically inserted every T seconds. The CM information 202 includes at least a CM flag indicating whether or not CM is in progress, shortened CM data start position information indicating the start position of the shortened CM data, and information for reproducing the shortened CM data, such as a PES packet ID. Is provided with shortened CM data reproduction information.

  The during-CM monitoring unit 106 polls the CM information 202 and determines that the CM is in progress if it can detect the in-CM flag. If the next CM information cannot be acquired after T seconds, it is determined that the CM has ended.

  FIG. 3 is a flowchart showing an operation when the skip request detection unit 107 detects the user's fast-forward key pressing in the first embodiment. When the fast-forward key is pressed (S301), the skip request detection unit 107 inquires to the CM monitoring unit 106 whether it is currently in CM (S302). If not during CM, a fast-forward playback request is sent to the playback data playback unit 105 to perform fast-forward playback (S303), and fast-forward playback is continued until information indicating that the CM monitoring unit 106 has transitioned to CM is transmitted. . In the case of CM, or in the case of transition to CM during fast-forward playback, the CM monitoring unit 106 sends the received CM information 202 to the CM data control unit 108. The CM data control unit 108 refers to the shortened CM data start position in the CM information 202 and skips to the shortened CM data start position (S304). Thereafter, the CM data control unit 108 refers to the shortened CM data playback information in the CM information 202 and plays back the shortened CM data (S305). When the reproduction of the shortened CM data is completed, the CM data control unit 108 determines whether the CM is in progress when the fast-forward key is detected (S306). If the CM data control unit 108 determines that the CM is in progress, a normal playback request is sent to the playback data playback unit 105 to perform normal playback (S307). On the other hand, if the program is in progress, a fast-forward playback request is sent to the playback data playback unit 105 for fast-forward playback (S308).

  FIG. 4 is a flowchart showing an operation when the transition to the CM during normal reproduction is detected and the operation is automatically switched to reproduction of the shortened CM data in the first embodiment of the present invention. The during-CM monitoring unit 106 detects whether or not the transition to the CM is performed during normal playback (S401) (S402). When it is detected that the CM monitoring unit 106 has transitioned to CM, the received CM information 202 is sent to the CM data control unit 108. The CM data control unit 108 refers to the shortened CM data start position in the CM information 202 and skips to the shortened CM data start position (S403). Thereafter, the CM data control unit 108 refers to the shortened CM data reproduction information in the CM information 202 and reproduces the shortened CM data (S404). When the reproduction of the shortened CM data is completed, the CM data control unit 108 sends a normal reproduction request to the reproduction data reproduction unit 105.

  It is also possible for the user to select whether the reproduction of the shortened CM data is executed according to a request from the user or automatically.

  FIG. 5 shows a comparison between the normal reproduction time and the reproduction time in the present embodiment. In normal playback, a 90-second CM is played back as usual between the programs A-1 and A-2. In this embodiment, the 90-second CM is replaced with a 3-second shortened CM, and program A-2 starts after the shortened CM.

  FIG. 6 shows an example of shortened CM in the present embodiment when there are three sponsors of company X, company Y, and company Z in program A. In many cases, three commercials are included in one commercial opportunity. In the present embodiment, one CM is replaced with a shortened CM for one company. This can prevent the CM time from becoming too long. In this embodiment, six CM periods from the start to the end of the program are equally divided into three companies, company X, company Y, and company Z, the first is company X, the second is company Y, and the third is company Z. , And so on.

  According to this configuration, even when the user fast-forwards to skip the CM, the optimal CM corresponding to a short time during the fast-forwarding of the CM can be displayed, so that the user is not uncomfortable. In addition, it is possible to broadcast a CM with a higher advertising effect.

(Embodiment 2)
FIG. 7 is a diagram showing a broadcast data configuration in Embodiment 2 of the present invention. In the CM in the broadcast data 601, CM information 602 is inserted every T seconds. The CM information 602 includes at least a CM flag indicating whether or not a CM is in progress, CM end position information indicating a time until the CM end position, and shortened CM data indicating which shortened CM data is to be reproduced. Is written. The shortened CM data is repeatedly transmitted in the broadcast data, and the broadcast data recording unit 102 records the shortened CM data in a different area from the broadcast program.

  FIG. 8 is a flowchart showing an operation when the skip request detection unit 107 detects the user's fast-forward key depression in the second exemplary embodiment. When the fast-forward key is pressed (S801), the skip request detection unit 107 inquires of the CM monitoring unit 106 whether or not the CM is currently under CM (S802). If not during CM, a fast-forward playback request is sent to the playback data playback unit 105 to perform fast-forward playback (S803), and fast-forward playback is continued until information indicating that the CM monitoring unit 106 has transitioned to CM is transmitted. . When CM is in progress, or when transitioning to CM during fast forward playback, the CM monitoring unit 106 sends the received CM information 602 to the CM data control unit 108. The CM data control unit 108 refers to the shortened CM data in the CM information 602 and requests the playback data extraction unit 104 for the shortened CM data to be played back. The reproduction data extraction unit 104 extracts the requested shortened CM data, and reproduces the reproduction data extracted by the reproduction data reproduction unit 105 (S804). When the reproduction of the reproduction data is completed, the CM data control unit 108 requests the reproduction data extraction unit 104 to reproduce the original reproduction data. When the playback data playback unit 105 starts playback, it refers to the CM end position information in the CM information 602 and skips to the CM end position (S805). If the CM data control unit 108 skips to the CM end position, the CM data control unit 108 determines whether the CM is in progress when the fast-forward key is detected (S806). If the CM data control unit 108 determines that the CM is in progress, a normal playback request is sent to the playback data playback unit 105 to perform normal playback (S807). On the other hand, if the program is in progress, a fast-forward playback request is sent to the playback data playback unit 105 for fast-forward playback (S808).

  FIG. 9 is a flowchart showing an operation when detecting a transition to CM during normal playback and automatically switching to playback of shortened CM data in Embodiment 2 of the present invention. The during-CM monitoring unit 106 detects whether or not the transition to the CM is performed during normal playback (S801) (S802). When the CM monitoring unit 106 detects the transition to CM, the received CM information 602 is sent to the CM data control unit 108. The CM data control unit 108 refers to the shortened CM data in the CM information 202 and requests the playback data extraction unit 104 for the shortened CM data to be played back. The reproduction data extraction unit 104 extracts the requested shortened CM data and reproduces the reproduction data extracted by the reproduction data reproduction unit 105 (S903). When the reproduction of the reproduction data is completed, the CM data control unit 108 requests the reproduction data extraction unit 104 to reproduce the original reproduction data, and when the reproduction data reproduction unit 105 starts reproduction, the CM data 202 includes The CM end position information is referred to and skipped to the CM end position (S905). Thereafter, a normal playback request is sent to the playback data playback unit 105.

  Also in the present embodiment, as in the first embodiment, the user can select whether the reproduction of the shortened CM data is executed according to a request from the user or automatically.

  According to this configuration, even when the user fast-forwards to skip the CM, the optimal CM corresponding to a short time during the fast-forwarding of the CM can be displayed, so that the user is not uncomfortable. In addition, it is possible to broadcast a CM with a higher advertising effect.

  In the recording / reproducing apparatus, the advertisement effect of the sponsor of the program and the user's CM skip operation for the user who wants to skip the CM at the time of reproduction are useful.
