    • 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.
    • 为了从记录介质再现传输流(TS),需要控制再现,以便在开始再现时不会溢出解码器缓冲器,或者当从特殊再现切换到正常再现时。 在从记录介质开始TS再现并且在正常再现和特殊再现之间进行切换时,在与用于记录的输入定时类似的定时执行流输出的再现技术和另一个再现 监视在解码器缓冲器中存储的数据量并根据受控数据量控制流输出的技术。

    • 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.
    • 在执行基于哪个编码的时钟频率随着时间而偏离的情况下,出现诸如不能输出适当的数字信号的问题。 为了解决这些问题,如果解码器对视频数据和音频数据进行解码,则在记录部中根据需要记录用于控制由时钟产生部恢复的时钟的频率的控制变量,并且当解码器解码时 记录在记录部分中的数据通过使用控制变量控制时钟产生部分,使得由计数器产生的系统时间信息与在接收数字广播节目时提取的时间信息同步。
