摘要： According to the present invention, there is provided an image reproducing apparatus for reproducing a digital broadcast based on the MPEG standard. When performing special reproduction by use of access-unit management information that is used to manage access units, the image reproducing apparatus reads ahead the access-unit management information and compares time stamps. As a result of the comparison, if it is judged that the absence of a piece of the access-unit management information exists, the special reproduction is then performed by use of simple information that is used to manage a stream.This makes it possible to continuously perform the special reproduction even if it becomes impossible to utilize the access-unit management information.

摘要： When performing special reproduction with a video recording and reproducing apparatus that reproduces an AV stream, a controller of the video recording and reproducing apparatus calculates a reproduction position in AU at desired time by referring to a timestamp that is added to the head of AU of two adjacent AV streams, gives an instruction of an I-picture exclusive mode to output only I-pictures to a decoder, and reproduces an I-picture.With such arrangement, in a video recording and reproducing apparatus which records and reproduces digital TV broadcasting, it becomes possible to execute special reproduction such as fast-forwarding reproduction of data in which MPEG2-TS is recorded even if the data does not contain position information of I-picture such as SI.
摘要翻译： 当利用再现AV流的视频记录和再现装置执行特殊再现时，视频记录和再现装置的控制器通过参考添加到AU的头部的时间戳在所需时间计算AU中的再现位置 相邻的AV流，给出I图像排他模式的指令，以仅将I图像输出到解码器，并再现I图像。 通过这样的布置，在记录和再现数字电视广播的视频记录和再现装置中，即使数据不包含位置信息，也可以执行诸如快速转发再现MPEG2-TS的数据的特殊再现 的I图像如SI。
