    • A video decoding device, in the case where a video of the progressive format is inputted, processes a frame as a picture, in the case where a video of the interlace format is inputted, processes a field as a picture. A video decoding device performs a common decoding process without depending on a moving image format regarding encoding on picture data. A video decoding device performs display control corresponding to a format of the both video by analyzing display control information in display control information analyzer. The display control information includes sequence unit display control information and picture unit display control information, the sequence unit display control information being commonly used in a display process of all pictures that belong to a sequence to be decoded and the picture unit display control information being individually used in a display process of a picture to be decoded. A second code string analyzer acquires each of the sequence unit display control information and the picture unit display control information from an extended information area in units of pictures.
    • 在输入逐行格式的视频的情况下,视频解码设备在输入隔行格式的视频的情况下将帧处理为图片,将字段处理为图片。 视频解码设备执行公共解码处理而不依赖于关于对图片数据进行编码的运动图像格式。 视频解码装置通过分析显示控制信息分析器中的显示控制信息来执行对应于两个视频的格式的显示控制。 显示控制信息包括序列单元显示控制信息和图片单元显示控制信息,序列单元显示控制信息在属于要解码的序列的所有图片的显示过程中被共同使用,并且图片单元显示控制信息是单独的 用于要解码的图片的显示过程中。 第二代码串分析器以图片为单位从扩展信息区获取每个序列单元显示控制信息和图片单元显示控制信息。

    • A video encoding device, in the case where a video of the progressive format is inputted, processes a frame as a picture, in the case where a video of the interlace format is inputted, processes a field as a picture. A video encoding device performs a common encoding process without depending on a video format regarding encoding on picture data. A video encoding device generates code string corresponding to a format of the both video by generating display control information corresponding to a format of the video and describing the display control information in the code string in display control information generator. The display control information includes sequence unit display control information and picture unit display control information, the sequence unit display control information being commonly used in a display process of all pictures that belong to a sequence to be decoded and the picture unit display control information being individually used in a display process of a picture to be decoded. A second code string generator stores each of the sequence unit display control information and the picture unit display control information in an extended information area generated in units of pictures.
    • 在输入逐行格式的视频的情况下,视频编码设备在输入隔行格式的视频的情况下将帧处理为图片,将字段处理为图片。 视频编码设备执行公共编码处理而不依赖于关于对图片数据进行编码的视频格式。 视频编码设备通过产生对应于视频的格式的显示控制信息并在显示控制信息产生器中描述代码串中的显示控制信息,产生与两种视频的格式相对应的代码串。 显示控制信息包括序列单元显示控制信息和图片单元显示控制信息,序列单元显示控制信息在属于要解码的序列的所有图片的显示过程中被共同使用,并且图片单元显示控制信息是单独的 用于要解码的图片的显示过程中。 第二代码串生成器将每个序列单元显示控制信息和图片单元显示控制信息存储在以图片为单位生成的扩展信息区域中。
