Description

  TECHNICAL FIELD The present invention relates to a technique for recording a broadcast material in a broadcast material recording device that can be randomly accessed and broadcasting according to an instruction from an automatic broadcast system, and setting a broadcast transmission start point when recording the sound material. .

  In the conventional analog input audio file, there is a product that performs automatic recording by detecting the rising edge of the audio, but there is no such product for an audio file that supports multi-channel audio for digital broadcasting.

  For this reason, when recording audio material, the audio material is once recorded on audio media such as MD, and the recording control device adjusts the timing to control the broadcast material recording device and audio media. The playback sound from the media was recorded on the broadcast material recording device.

  FIG. 7 is a diagram showing a recording image in the case where the reproduced sound from the conventional audio media is recorded in the broadcast material recording apparatus.

  When recording the playback sound (main part) from the audio media in the broadcast material recording device, the pre-discard section 702 of about several seconds (for example, 2 seconds) is recorded before the recorded sound (main part) 701 to the broadcast material recording device. After the sound (main part) 701, a post-discard portion 703 is added for about several seconds (for example, 2 seconds).

  For this reason, when recording the playback sound (main part) from the audio media in the broadcast material recording device, the recording of the broadcast material recording device is started at the recording start point 704 based on the recording command from the recording control device, and the pre-discard unit 702 The audio media playback is started at the audio media playback start point 705 after a lapse of several seconds (for example, 2 seconds), and the playback audio (main part) 706 from the audio media is recorded in the broadcast material recording device. I have to. In this case, the broadcast transmission start point of the recorded reproduced sound (main part) 706 is 705.

  FIG. 7 shows a case in which the time length of the recorded audio (main part) 701 to the broadcast material recording apparatus is the same as the time length of the reproduced voice (main part) 706 from the audio media. ) If the time length of 706 is shorter than the time length of the recorded audio to the broadcasting material recording device (main part) 701, the recorded voice (main part) is usually added with a silent section before and after the time length adjustment. It should be the same length as 701. Therefore, audio media with a silent section added in advance is prepared.

  FIG. 8 is a diagram showing a recording image in the case where the playback sound from the sound media to which the conventional silent section is added in advance is recorded in the broadcast material recording apparatus.

  The reproduced sound from the audio media has silent sections 802 and 803 added before and after the reproduced sound (main part) 801, and has the same time length as the recorded sound (main part) 701.

  When recording the playback sound (main part) from the audio media with the silent section added in advance to the broadcast material recording device, the recording of the broadcast material recording device is started at the recording start point 704 based on the recording command from the recording control device. At the audio media playback start point 705 after a lapse of several seconds (for example, 2 seconds) corresponding to the discard unit 702, playback of the audio media is started, and a silent section 802 from the audio media, playback audio (main part) 801, and silence The section 803 is recorded in the broadcast material recording device. In this case, the broadcast transmission start point of the recorded reproduction sound (main part) 801 is 705.

  FIG. 9 is a diagram showing a recording image when a conventional LIVE sound is recorded in a broadcast material recording apparatus.

  When recording a LIVE sound (main part / sound) in a broadcast material recording device, since it is a LIVE sound, before the position of the audio media playback start point 705 after about several seconds (for example, 2 seconds) corresponding to the pre-discard unit 702 Thus, the LIVE voice (main part / sound) 901 is started, and the LIVE voice (main part / sound) 902 is started after the position of the audio media playback start point 705. Moreover, since the LIVE voices 901 and 902 are sounded, it is necessary to set a silent section before.

  Note that a technique for controlling recording of a broadcast material into a broadcast material recording device by a recording control device is known and disclosed in, for example, Patent Document 1.
