High-definition Blu-Ray Discs

Introduction Blu-ray vs. HD DVD
In recent years, high-definition (HD) television and HD optical discs entered the market
Two HD formats have appeared in the DVD market, both claiming to be the rightful successor to the DVD throne:
Blu-ray (developed by Sony/Phillips)
HD DVD (developed by Toshiba)
Measured by most performance metrics these two technologies are the same, except that Blu-ray has significantly larger capacity (66%).
However, Blu-ray appears to have greater network support
Blu-ray vs. HD DVD Future
While the format war rages on, entirely different outcomes are possible:
LG has introduced a dual-format player and drive
Internet may replace the DVD as a movie delivery vehicle
International view: Japan (96% Blu-ray), Europe (pushing for open licensing of both formats), China (proprietary HD format), India (small $ market), South America (unknown); Xbox 360 but still no PS3)
History of Format Wars
Before HD, IBM arbitrated a standard DVD format intended to avoid a format war, but the outcome favored Toshiba regarding royalties, leaving Sony unhappy
In response, Sony began developing the next generation of high-definition optical media
Toshiba followed suit with its own HD technology
While there were many “peace talks”, neither party reached agreement
Comparison: VHS vs. Betamax War
Despite Beta’s superior quality, VHS won the war because of its strong “content” network
