MPEG Transport Stream (TS) is a standard digital container format for the transmission and storage of audio, video, and data, maintained by the Moving Picture Experts Group. It is primarily utilized in broadcast systems such as DVB, ATSC, and IPTV, as well as for streaming media over unreliable networks where packet loss may occur. While inherently safe, the format lacks native encryption or integrity verification, necessitating external conditional access systems for secure commercial distribution.
