Abstract

A method of preprocessing video entertainment content consistent with certain embodiments involves encoding the video entertainment content using a digital video encoding process to produce encoded digital video content; determining an amount of bandwidth consumed by the encoded digital video content; determining that an amount of bandwidth available in a transport stream is adequate to transport the encoded digital video content plus a segment of supplemental data; assigning a first packet identifier to packets containing the digital video content; packetizing the segment of supplemental data; assigning a second packet identifier to packets containing the supplemental data; and combining the supplemental data with the digital video content to produce a preprocessed digital signal. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
