'''Program stream''' ('''PS''' or '''MPEG-PS''') is a [[container format (digital)|container format]] for multiplexing [[digital audio]], [[video]] and more. The PS format is specified in [[MPEG-1]] Systems and [[MPEG-2]] Part 1, Systems (ISO/IEC standard 13818-1).

Program streams are created by combining one or more [[Packetized Elementary Stream]]s (PES), which have a common time base, into a single stream. It is designed for reasonably reliable media such as disks, in contrast to [[transport stream]] which is for data transmission in which loss of data is likely. Program streams have variable size records and minimal use of [[start code]]s which would make off-over the air reception difficult.
