Abstract
Methods and apparatus for transmitting audience measurement data or interactive data via a compressed data bitstream are disclosed. Example methods disclosed herein include eliminating a first type of data within a compressed data bitstream, and packing a second type of data within the compressed data bitstream to occupy a first location within the compressed data bitstream from which the first type of data is eliminated. Disclosed example methods also include inserting at least one of audience measurement data or interactive data in a second location within the compressed data bitstream that is expanded as a result of the packing of the second type of data to form a modified compressed data bitstream, and transmitting the modified compressed data bitstream.
