    • A decoder (200) includes a transport engine (205) configured to receive programs and extract timing information and timestamps embedded in the programs. An adder (215) is configured to add a set of timing offsets to the sets of timing information to adjust the timing information from a first time basis to a second time basis. Sums of the timing offsets and the timing information are referred to the mapped-timing information. A correction engine (235) is configured to update the timing offsets as timing information is encountered in the programs, and an offset register is configured to: receive the timing offsets, store the timing offsets, and transfer the timing offsets to the adder. The adder is also configured to add the timing offsets to the timestamps to adjust the time basis of the timestamps from the first time basis to the second time basis. A program is decoder configured to receive the adjusted timestamps to decode the programs.
    • 解码器(200)包括被配置为接收节目并提取嵌入在节目中的定时信息和时间戳的传输引擎(205)。 加法器(215)被配置为将一组定时偏移量添加到定时信息集合,以便从第一时间基准到第二时间基准调整定时信息。 定时偏移和定时信息的和被称为映射时序信息。 校正引擎(235)被配置为在程序中遇到定时信息时更新定时偏移,并且偏移寄存器被配置为:接收定时偏移,存储定时偏移,并将定时偏移传送给加法器。 加法器还被配置为将时间偏移量添加到时间戳,以便调整从第一时间到第二时间的时间戳的时间基准。 程序是被配置为接收调整的时间戳以解码程序的解码器。
