Exploratory talks between Japanese rivals Sony and Toshiba about establishing a common format for next-generation DVDs have been joined by representatives of other industry giants, Matsushita's Panasonic and Philips.
All are keen to find a way to end the three-year stand-off which is potentially holding back the industry's growth.
Reuters quoted a source close to the talks: "Discussions are taking place, but it's very complex, both in terms of technology but also because so many companies have a stake in this."
Sony and Toshiba confirmed the talks last week. A report in the Nihon Keizai business daily said a way forward between Sony's Blue-ray technology and Toshiba's HD DVD optical discs could come as early as this month.
Sony's Blu-ray technology is backed by Philips, Dell, Samsung and Matsushita. In December, Disney announced it was opting for Sony's Blu-ray format for several future releases.
