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： High audibility output is realized when audio output is provided in special playback. In special playback with audio output, skip/repeat control is done so that decoding and outputting of the audio data is periodically repeated/skipped during part of one frame. The output level may be corrected so as to emphasize appropriate frequency components. This realizes good audio output. In addition, the skip/repeat control and output level correcting methods are changed according to characteristics of the audio data to be reproduced. Also, this realizes good audio output.

摘要： For reproduction of transport stream (TS) from a recording medium, it is necessary to control the reproduction so as not to overflow the decoder buffer at the time of starting the reproduction and or when switching to the normal reproduction from special reproduction. At the times of starting the TS reproduction from a recording medium and switching between the normal reproduction and the special reproduction, selection is made as appropriate between a reproduction technique which performs stream output with timing similar to the input timing used for recording, and another reproduction technique which monitors data amount stored up in a decoder buffer and controls stream output in accordance with the controlled data amount.

摘要： Where a clock frequency based on which encoding is performed has deviated over time, problems such as that an appropriate digital signal can not be outputted occur. To solve the problems, it is arranged such that when a decoder decodes video data and audio data, a control variable for controlling a frequency of a clock recovered by a clock generating portion is recorded as needed in a recording portion, and when the decoder decodes data recorded in the recording portion, the clock generating portion is controlled by using the control variable so that system time information generated by the counter synchronizes with time information extracted upon reception of a digital broadcasting program.
