    • Auxiliary AV data of a lower rate is formed in an auxiliary AV data converting unit on the basis of video and audio data of a main line system. The audio data of the main line system in which the number of channels is equal to 0 and 4 or 8 channels can exist mixedly. In the auxiliary AV data, the number of channels of the audio data is fixed to 8 channels. Audio data showing silence is outputted to the channels which do not correspond to the channels of the audio data of the main line system of the auxiliary AV data. Since the number of channels of the audio data of the auxiliary AV data is fixed irrespective of the number of channels of the audio data of the main line system, the editing or searching operation using the auxiliary AV data can be executed without paying attention to a change in the number of channels of the audio data of the main line system, or the like.
    • 基于主线系统的视频和音频数据,在辅助AV数据转换单元中形成较低速率的辅助AV数据。 其中信道数量等于0和4或8个信道的主线路系统的音频数据可以混合存在。 在辅助AV数据中,音频数据的通道数固定为8个通道。 显示静音的音频数据被输出到与辅助AV数据的主线系统的音频数据的声道不对应的声道。 由于辅助AV数据的音频数据的频道数量是固定的,与主线系统的音频数据的频道数无关,所以可以执行使用辅助AV数据的编辑或搜索操作而不关注 改变主线系统的音频数据的频道数量等。

    • Files are capable of being exchanged between a broadcast device and a personal computer. In a file of an AV multiplex format, a header (size and type information) of a skip atom of QT is described at the beginning (run-in) that is ignored in an MXF file. An MXF header is described in the skip atom that is skipped over in a QT file. A movie atom and a mdat header of QT are described in a filler that is ignored in the MXF file. In other words, a file header portion of the AV multiplex format satisfies both the structure of the MXF file and the structure of the QT file. With this file structure, a file of the AV multiplex format can be recognized by both an MXF standard basis edit device and a QT software installed PC. The present invention can be applied to a picture record device.
    • 文件能够在广播设备和个人计算机之间交换。 在AV多路复用格式的文件中,在MXF文件中忽略的起始(运行)中描述了QT的跳过原子的标题(大小和类型信息)。 在QT文件中跳过的跳过原子中描述了MXF头。 在MXF文件中忽略的填充程序描述了QT的电影原子和mdat标题。 换句话说,AV多路复用格式的文件头部分满足MXF文件的结构和QT文件的结构。 利用该文件结构,可以通过MXF标准编辑装置和安装有QT软件的PC来识别AV多路复用格式的文件。 本发明可以应用于图像记录装置。
