High-definition video
HD content
Most computers are capable of HD or higher resolutions over VGA, DVI, HDMI and/or DisplayPort. The optical disc standard Blu-ray Disc can provide enough digital storage to store hours of HD video content. Digital Versatile Discs or DVDs (that hold 4.7 GB for a Single layer or 8.5 GB for a double layer), are not always up to the challenge of today's high-definition (HD) sets. Storing and playing HD movies requires a disc that holds more information, like a Blu-ray Disc (which hold 25 GB in single layer form and 50 GB for double layer) or the now-defunct High Definition Digital Versatile Discs (HD DVDs) which held 15 GB or 30 GB in, respectively, single and double layer variations. Blu-ray Discs were jointly developed by 9 initial partners including Sony and Phillips (which jointly developed CDs for audio), and Pioneer (which developed its own Laser-disc previously with some success) among others. HD-DVD discs were primarily developed by Toshiba and NEC with some backing from Microsoft, Warner Bros., Hewlett Packard, and others. On February 19, 2008 Toshiba announced it was abandoning the format and would discontinue development, marketing and manufacturing of HD-DVD players and drives.
