Abstract:
1. A method, performed in a digital home communication terminal (DHCT), of assembling a multimedia transport IPTV stream, the method comprising the steps of: receiving a media access control layer (MAC) layer packet through a binding to a MAC-layer network interface driver, the MAC-layer packet containing one or more multimedia transport packets; applying at least one criteria filter to the received MAC-layer packet to determine whether the one or more multimedia transport packets contained within the received MAC-layer packet meets criteria associated with the criteria filter; applying a PID filter to the received MAC-layer packet to determine whether the received packet contains one or more multimedia transport packets having a PID field matching at least one PID value stored by a user as a preferred PID in a registration data table, wherein the registration data table comprises both the criteria and user-stored PID preferences previously registered by a stream assembly logic; for each multimedia transport packet meeting the applied criteria filter criteria and matching the PID filter, copying the respective multimedia transport packet to an elementary stream buffer; and for each multimedia transport packet not meeting the applied criteria filter criteria or not matching the PID filter, copying the respective multimedia transport packet to a protocol stack.
