    摘要： A method and apparatus for staggercasting a plurality of content representative signals includes encoding a first and a corresponding second signal representing each of the plurality of content representative signals. A composite signal is generated comprising the plurality of first and second encoded signals. In the composite signal, each respective second encoded signal is delayed with respect to the corresponding first encoded signal. The first and second encoded signal representing a selected one of the content representative signals is extracted to reproduce the selected content representative signal. The extracted first encoded signal is decoded if an error is detected in the extracted second encoded signal, otherwise the extracted second encoded signal is decoded. When a different content representative signal is newly selected, the first extracted encoded signal is decoded until the delayed second extracted encoded signal is available.

    摘要翻译： 用于交错多个内容代表信号的方法和装置包括编码表示多个内容代表信号中的每一个的第一和相应的第二信号。 产生包括多个第一和第二编码信号的复合信号。 在复合信号中，每个相应的第二编码信号相对于对应的第一编码信号被延迟。 提取表示选择的一个内容代表信号的第一和第二编码信号，以再现所选择的内容代表信号。 如果在提取的第二编码信号中检测到错误，则提取的第一编码信号被解码，否则提取的第二编码信号被解码。 当新选择不同的内容代表信号时，第一提取的编码信号被解码，直到延迟的第二提取的编码信号可用。
