A new report has predicted that global digital television is being driven by China, accounting for a quarter of all digital TV households by 2012.

According to figures published by Informa Telecoms and Media in its Global Digital TV report, more than 264 million digital homes will be added between the end of 2007 and the end of 2012, more than double the current total, with China accounting for 60 million of the extra homes.

The figures also predicted that other significant rises will come in the US, with 39 million more digital TV households; in Japan (20 million) and India (23 million). These four countries combined will account for 54 percent of additional digital households.

Approximately 43 percent of the world's TV homes will receive digital signals by 2012.

"Digital growth will accelerate as the decade progresses, especially outside North America and Western Europe," the Hollywood Reporter quoted the report, as saying.

The forecast also said that by 2012, this will amount to 504 million homes with digital television: 97 million will be using digital terrestrial TV (DTT); 249 million will have cable; 120 million will have satellite; and 37 million will have IPTV.

However, the year will not see the end of the process.

"By 2012, most of Western European and North American homes will receive digital TV signals. However, there will still be 668 million analog homes across the globe -- indicating that there is still significant room for expansion beyond that forecast date," Simon Murray, Informa's principal analyst, said.

According to the report, already by the end of 2007 there will be a surge in digital TV: nearly 54 million digital TV households will be added, bringing the global total to 239 million.

Over half of the new digital households, 28 million, will be through digital cable subscriptions. Satellite delivery will account for 36 percent of the total, or 87 million homes; IPTV will have account for 10 million; and DTT 47.8 million.

The report has predicted that digital penetration of TV households will reach 22 percent by year-end, with the North American penetration rate exceeding 68 percent and Western Europe at 52 percent. A further 52 million digital homes will be added to the total in 2008. (DVOL本文转自：中国DV传媒 http://www.dvol.cn)
