  • Patent number: 11012171
    Abstract: A method for adding Time Marker Packets, TMPs, comprising Metadata to an MPEG-2 transport stream transmitted via a broadcast network for providing a deterministic transport stream, comprising providing feeds of data from at least one source, where the feeds comprise payload packets being referenced by a common 1 PPS reference, and where the feeds are input to at least one multiplexer, MUX; providing Time Marker Packets, TMPs, as input to each multiplexer, where each TMP comprises a plurality of time stamps per second measured relative to said 1 PPS reference, and each TMP has a value representing an Absolute Program Clock Reference, APCR, at the time of transmission, where the APCR is based on the Epoch time, and where the TMP packet further comprises PCR, OPCR locked to said 1 PPS and UTC leap seconds.
