Development of CBHD, heavily based on the HD DVD standard, was greatly helped by Japanese engineers. In particular, Hisashi Yamada, former Chief Technology Fellow at Toshiba's Digital Media Network, often referred to as the "father of DVD," has played a key role in China's plan to create its own high-definition consumer video format.
CBHD differs from HD DVD in several key areas. CBHD uses the PRC government-owned AVS video codec, DRA audio codec, and a new copy protection system, DKAA, as an alternative to HD DVD's and Blu-ray's AACS. CBHD's developers claim that the format contains more copy protection features and is part of a big push by China to fight piracy in addition to reducing their reliance upon foreign patents with their associated royalty payments.
CBHD also eschews HD DVD's Advanced Content navigation system in favor of a Chinese system called CETC.
Like HD DVD, CBHD discs have a capacity of 15GB single-layer and 30GB dual-layer and can utilise existing DVD production lines.

Famous quotes containing the word technology:
“Our technology forces us to live mythically, but we continue to think fragmentarily, and on single, separate planes.”
—Marshall McLuhan (1911–1980)
“If the technology cannot shoulder the entire burden of strategic change, it nevertheless can set into motion a series of dynamics that present an important challenge to imperative control and the industrial division of labor. The more blurred the distinction between what workers know and what managers know, the more fragile and pointless any traditional relationships of domination and subordination between them will become.”
—Shoshana Zuboff (b. 1951)
