Yet due to a certain policy factor, live broadcast of digital TV in China is still being restricted to some extent. Anyway, nothing can hinder its development trend in the long term.

Though compared with developed countries, China is lagged far behind in the field of digital TV, yet it made rapid progress in 2005; altogether 4.13 million Chinese subscribed digital TV, increasing by over twofold compared to the previous year.
