The PXGF streaming and file format provides a framework for the streaming and storage of sampled data along with the meta data required to process the sampled data. It is a streaming format in that synchronization can be regained if lost.
A file using the PXGF format contains a PXGF stream with a prepended header. The header was designed to allow an application to identify a file without processing the file. The capability to identify files becomes more important as file sizes get bigger. The PXGF file format supports large file sizes.
