Satellite fleet operator Eutelsat has signed on its 100th high-definition television channel, Sky Italiaโ€™s Sky Sport 1HD, bringing the total number of HDTV channels in Europe and the Middle East โ€” including those not carried by โ€” to 243, Paris-based announced Oct. 7.

Eutelsat began transmitting high-definition television (HDTV) broadcasts in 2005 and has seen its HDTV channel count double in the last 15 months. The company said a survey it commissioned in 37 nations in Europe and the Middle East found that more than 10 million households โ€œintend to move into an HD environment over the next year.โ€

Satellite fleet operators are counting on the move toward large HD-Ready flat-screen televisions to accelerate demand for HDTV, which uses more satellite bandwidth than standard-definition digital programming. Eutelsat has begun experimenting with 3-D television, which requires still more bandwidth.
