Title
(EN) Method and apparatus for writing information on picture data sections in a data stream and for using the information
(ZH) 写关于数据流中的图像数据段的信息以及使用该信息的方法和装置
Abstract
(EN) When recording video data in a plurality of recording blocks on a recording medium while organizing the video data into navigation units, the present invention records the size of the first picture data in each of the navigation units expressed in terms of the number of transport packets carrying the first picture data. Alternatively, the present invention adds 128-byte header information to each of the recording blocks, in which case if a recording block contains the last data of the first picture in each of the navigation units, position information for indicating the end position is written in the header information. The present invention thereby can specify the data section of the first picture in each navigation unit precisely.
(ZH)

当将视频数据记录在记录介质上的多个记录块中同时将该视频数据组织成导航单元时,本发明记录以携带首图像数据的传输包的数目形式表达的、各导航单元中的首图像数据的大小。或者,本发明向各记录块添加128字节的首部信息,在这种情形中,如果一记录块包含各导航单元中的首图像的结尾数据,则用于指定结束位置的位置信息被写在首部信息中。本发明由此可精确指定每个导航单元中的首图像的数据段。
