Patent ID: 8170122

Claim:
A digital media advertisement compression system for inserting advertisements into a statistically multiplexed digital transmission stream containing a plurality of digital program streams with a plurality of advertising opportunities, the system comprising: a determination module for determining a first bit rate profile for a first advertising opportunity and a second bit rate profile for a second advertising opportunity and for specifying a predetermined bit rate profile for compression of a first digital media advertisement and a second digital media advertisement, wherein the predetermined bit rate profile is based on the first and second bit rate profiles; a compression module for compressing the first digital media advertisement and the second digital media advertisement according to the predetermined bit rate profile, such that the predetermined bit rate profile provides a limit to the sum of the bitrates bit rates of the first and second digital media advertisements; and an insertion module for inserting the compressed digital media advertisements into the statistically multiplexed digital transmission stream within the first and second advertising opportunities.
