    • An apparatus for processing an informational signal includes a first processing section for receiving the informational signal, executing a first processing on the informational signal, and outputting the processed informational signal. The apparatus also includes a second processing section, which is located at a posterior stage of the first processing section, for receiving the processed informational signal and executing a second processing on the processed informational signal. The apparatus further includes transmitting device for transmitting meta-information corresponding to each predetermined period of time in the informational signal from the first processing section to the second processing section. The processing in the second processing section is controlled based on the meta-information transmitted by the transmitting device.
    • 用于处理信息信号的装置包括:第一处理部分,用于接收信息信号,对信息信号执行第一处理,并输出处理过的信息信号。 该装置还包括位于第一处理部分的后级的第二处理部分,用于接收经处理的信息信号并对处理的信息信号执行第二处理。 该装置还包括发送装置,用于将信息信号中对应于每个预定时间段的元信息从第一处理部分发送到第二处理部分。 基于由发送装置发送的元信息来控制第二处理部中的处理。
