Abstract: A method for switching between two redundant bitstreams. The first bitstream may be presented to a first pipeline. The second bitstream may be presented to a second pipeline. The first bitstream and the second bitstream may contain redundant information received from independent sources. If the first bitstream fails, the method may present an output of the second pipeline to the output pipeline. Data in a buffer in the second pipeline may be used to pass a next frame to the output pipeline. A size of a buffer of the first pipeline and a size of the buffer in the second pipeline may be adjusted based on a time of reception of the first and the second bitstream.

Abstract translation: 一种用于在两个冗余比特流之间切换的方法。 第一比特流可以呈现给第一流水线。 第二比特流可以被呈现给第二流水线。 第一比特流和第二比特流可以包含从独立源接收的冗余信息。 如果第一比特流失败，则该方法可以将第二流水线的输出呈现给输出流水线。 可以使用第二流水线中的缓冲器中的数据将下一帧传递到输出流水线。 可以基于第一和第二比特流的接收时间来调整第一流水线的缓冲器的大小和第二流水线中的缓冲器的大小。
