Originally, BD-ROMs stored video up to 1920 × 1080 pixel resolution at up to 60 (59.94) fields per second. Currently, with UHD BD-ROM, videos can be stored at a maximum of 3840 × 2160 pixel resolution at up to 60 (59.94) frames per second, progressively scanned.
Initial Blu-ray Disc titles often used MPEG-2 video, which requires the highest average bitrate and thus the most space, to match the picture quality of the other two video codecs. As of July 2008 over 70% of Blu-ray Disc titles have been authored with the newer compression standards: AVC and VC-1. [ 6 ]
Ultra HD Blu-ray (4K Ultra HD, UHD-BD, or 4K Blu-ray) [2] [3] is a digital optical disc data storage format that is an enhanced variant of Blu-ray. [4] Ultra HD Blu-ray supports 4K UHD (3840 × 2160 pixel resolution) video at frame rates up to 60 progressive frames per second, [ 4 ] encoded using High-Efficiency Video Coding . [ 4 ]
The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio. Alternative analog video transport technologies carrying higher resolutions than 960H include HD-TVI, HDCVI, and AHD.
Since BD-RE 5.0/BD-R 4.0, a read speed of 4× is mandatory for UHD support. [8] Note: If write verification is enabled, as it may be by default on some burning software, the write will take longer to complete. Erasing a BD-RE is not necessary since existing data can be directly overwritten.
The format war's resolution in favour of Blu-ray was primarily decided by two factors: shifting business alliances, including decisions by major film studios and retail distributors, [37] and Sony's decision to include a Blu-ray player in the PlayStation 3 video game console. [38] [39]

In the history of optical storage media there have been and there are different optical disc formats with different data writing/reading speeds.. Original CD-ROM drives could read data at about 150 kB/s, 1× constant angular velocity (CAV), [1] the same speed of compact disc players without buffering.
