The number of households worldwide with HDTV service delivered via satellite, cable TV, IPTV and over the air will grow to 255 mln by the end of 2013, up from an estimated 45 mln as of the end of 2007, according to IMS Research. Blu-ray Disc market will experience strong growth during the next five years, particularly as Blu-ray Disc drives in new PCs become more common, reaching a forecast $46 bln in revenues in 2013. IMS Research forecasts the number of DTH HD households to grow 27.5% annually to 97 mln by the end of 2012. Skewing the numbers is the fact that 62% of cable customers worldwide are in the Asia-Pacific region where there’s been a slow conversion from analog to digital service.
