To generate the PS, the multiplexer will interleave the (two or more) packetized elementary streams. The interleave lower bound is an asymptotic lower bound on dynamic optimality. Links do not interleave data from several packets. The analogous operation to an out shuffle for an infinite sequence is the interleave sequence. The ABA problem occurs when multiple threads (or processes) accessing shared data interleave. The container file is used to identify and interleave different data types. Radiolarites deposited in relatively shallow depths can interleave with carbonate layers. SpinRite was originally written as a hard drive interleave tool. The Hi-Res mode on the Apple II was also peculiar for its 64&colon;1 interleave factor. The file interleave is 10 blocks, while the directory interleave is 3 blocks. Audio Video Interleave from Microsoft followed in 1992. There, real and imaginary part interleave each other. The technology introduced a file format designed to store digital video, Audio Video Interleave (AVI). The typical character transmission delay is 12.8 seconds with Long Interleave Mode.
