Important.png Note: The correct title of this article is channelscan_dtv_multiplex table. It appears incorrectly here due to technical restrictions.

The channelscan_dtv_multiplex table contains the information about the multiplex streams of previous channel scans. It is referenced by the channelscan_channel table and simplifies re-scanning for channels if the capture card is removed and re-added.

This table is mostly similar to the dtv_multiplex table.
