Abstract

Apparatuses and methods may include receiving a data flow comprising a plurality of packets, identifying static data and dynamic data in packet headers of the plurality of packets, generating a plurality of protocol packets by removing the static data from the packet headers while retaining the dynamic data, generating signaling data based on the static data, and generating a transport stream comprising the signaling data and the protocol each data flow packets.
