    • A transport stream (TS) is recorded and the recorded TS is reproduced simultaneously. An input PID parser extracts the first packet only to be recorded, the second packet to be recorded and to be used for controlling, and the third packet to be used only for controlling from among the TS packet that constitutes the TS supplied from a descrambler. The first and second packets are supplied to a receiver and supplied to a hard disk drive (HDD) for recording. The second and third packets are supplied to an MUX. On the other hand, the TS packet stored in the HDD is read out and supplied to the MUX by way of an output PID parser. The MUX multiplexes the second or third packet supplied from the input PID parser and the TS packet read out from the HDD, and supplies the multiplexed packet to a CPU that controls a descrambler or the like.
    • 记录传输流(TS),同时记录记录的TS。 输入PID解析器仅提取要被记录的第一数据包,要被记录并用于控制的第二数据包,以及仅用于从构成从解扰器提供的TS的TS数据包中进行控制的第三数据包。 第一和第二分组被提供给接收机并提供给用于记录的硬盘驱动器(HDD)。 第二和第三分组被提供给MUX。 另一方面,存储在HDD中的TS分组被读出并通过输出PID解析器提供给MUX。 MUX复用从输入PID分析器提供的第二或第三分组和从HDD读出的TS分组,并将多路复用分组提供给控制解扰器等的CPU。
