Related to Blu-ray Disc: HD DVD, External hard drive


The current optical disc format for high-definition (HD) video at 2K resolution (for 4K Blu-ray, see Ultra HD Blu-ray). Developed primarily by Sony, Blu-ray discs have the same diameter as DVDs, but the pits are a third the size on tracks packed more tightly together. As a result, movies with 1,080 lines of resolution can be recorded, compared to 480 or 576 for a DVD (U.S. NTSC format is 480 lines, PAL format is 576 lines). Blu-ray players read CDs and DVDs, support navigation via menus programmed in Java and feature advanced audio and video formats (see Java, Dolby Digital, DTS, H.264, VC-1).

Commentary and Extra Content
All players support Profile 1.0. Bonus View (Profile 1.1) requires 256MB of flash memory and uses a second A/V codec for running picture-in-picture commentary. BD-Live (Profile 2) requires 1GB of flash to access content from the Internet such as scenes that were cut, interviews with the director and actor history. See BD-Live.

Blu-ray History
In 2003, the first Blu-ray recorders were sold in Japan, and in 2006, Sony's PlayStation 3 was one of the early products to feature a Blu-ray drive (see PlayStation). For several years, Blu-ray competed with HD DVD for the new high-res standard, but HD DVD was later abandoned (see HD DVD). See HD formats, Blu-ray 3D, DVD and DTV.
