    • An apparatus comprises means (31) for receiving a broadcast TS (transport stream) and detecting layer information in each broadcast TS packet, means (32) for delaying the broadcast TS, means (37) for inputting an MPEG-TS for rewriting, means (33) for generating a signal for selecting a delayed broadcast TS packet when the layer information does not indicate a predetermined layer, and generating a signal for selecting an MPEG-TS packet for rewriting when the layer information indicates the predetermined layer, and means (38) for selectively outputting the delayed broadcast TS packet and the MPEG-TS packet for rewriting. The apparatus may further comprise means (34) for modifying a PAT packet of the broadcast TS, and means (35) for modifying an NIT packet of the broadcast TS, where the apparatus can selectively output the modified PAT packet and modified NIT packet.
    • 一种装置,包括用于接收广播TS(传输流)和检测每个广播TS分组中的层信息的装置(31),用于延迟广播TS的装置(32),用于输入用于重写的MPEG-TS的装置(37) (33),用于当层信息不指示预定层时产生用于选择延迟广播TS分组的信号,并且当层信息指示预定层时生成用于选择用于重写的MPEG-TS分组的信号,以及装置 38),用于选择性地输出延迟的广播TS分组和用于重写的MPEG-TS分组。 该装置还可以包括用于修改广播TS的PAT分组的装置(34),以及用于修改广播TS的NIT分组的装置(35),其中该装置可以选择性地输出修改的PAT分组和修改的NIT分组。
