ABI Research anticipates set top box shipments of just 46.11 mln in 2006, as opposed to 2005’s figure of 50.78 mln. By 2011, however, the forecasts are more bullish, showing a recovery to 53.72 mln units. Some DBS providers are positive about the numbers of STBs they expect to recycle, citing hoped-for exchange rates of 80% or more. ABI Research believes such estimates are optimistic, however, and proposes that the average STB recycle rate will typically be closer to 30% to 40%.
