NOTE – Has less or different back channel data to collect. Inability to collect all the data you can collect on the older boxes.

NOTE – FourthWall Media’s Event Stream Collector stores up to seven days of second-by-second measurement data on even the least capable legacy Set-Top Boxes, so no special treatment is required for any two-way legacy STB. Data is normally uploaded to the collection server daily, and the seven day cache is provided merely for fault-tolerance. (Source: FourthWall Media)
