Blu-ray Disc, one of two formats being promoted as a replacement for today's DVDs, picked up support this week from Lions Gate Home Entertainment and Universal Music Group.
Lions Gate said it will release movies, television programs and other titles on Blu-ray Disc when compatible players are launched in North America. At present such players are expected to be available some time in 2006, although no manufacturer has announced a more specific launch date.
The recent adoption by the Blu-ray Disc Association, the format's standards-setting body, of a content protection and management system was cited by Lions Gate as being important in its decision. The system combines AACS (Advanced Access Content System) with BD+, a system that allows the protection system to be renewed should it be compromised, and ROM Mark, which is intended to guard against mass production piracy or duplication.
As soon as Blu-ray Disc hardware comes out it is likely to be up against HD-DVD-based equipment. HD-DVD, backed by Toshiba, NEC and the DVD Standards Group, is expected to first appear in stores before the end of this year. Again specific launch dates haven't been disclosed. The amount of hardware or software that will be available at launch is also unknown at present.
Blu-ray Disc is backed by a much larger number of companies including such big-name vendors as Sony, Panasonic, Samsung, Dell, HP, Apple and Philips.
Content makers are more evenly split between the two formats.
HD-DVD can count on support from Warner Home Video, Universal Pictures and Paramount Pictures Corp.
On the Blu-ray Disc side are Twentieth Century Fox, Walt Disney Pictures and Television, Sony's Pictures group – and now Lions Gate.
Despite these initial pledges of support, most providers have said they will release content on the competing format if it begins to become popular.
Universal Music Group announced earlier in the week that it has joined the Blu-ray Disc Association, the format's standards-setting body, as a contributing member. As such the company, in return for a $20,000 (£11,082) annual fee, can participate in group meetings, board meetings, seminars and play a part in creating standards.
Universal Music Group, which is a unit of Vivendi Universal, stopped short of saying it would release products on Blu-ray Disc.
