New page

MPEG

MPEG-TS or TS and MPEG-PS or PS are digital container format.

Elementary Stream (ES)
Packetized Elementary Stream (PES) = contains timestamp

Program Stream PS -> variable-length packet for error-free medium (e.g. optical and hard disks) / common clock / 1 video PES + n audio PES

Transport Stream TS -> fixed-sized packet PES (188 bytes) for transmission and digital broadcasting / multiple with different clocks

In a single TS, multiple programs (channels) can be multiplexed.
