The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [6] [7] [8] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [9] the pattern of the position detection markers was determined by finding the least-used sequence of ...
Rectangular Micro QR Code encodes digits 0–9 in numeric mode. [2]: 7.4.3 The number sequence is split into 3 digits which converted to 10 bits (000 - 999). Last 2 and 1 numbers are encoded in 7 and 4 bits. rMQR Code in numeric mode encodes 001 as mode indicator, then numbers counter and then numbers sequence converted into bits.
The eight regions each correspond to a value which is a power of 2: Region 1 corresponds to 1 (2 0), Region 2 to 2 (2 1), Region 3 to 4 (2 2), and so on through Region 8, which corresponds to 128 (2 7). The values of each region that the disc is not encoded for are added together to give the value in the file. For example, a disc that is ...
As a result, the DVD specification provided a storage capacity of 4.7 GB (4.38 GiB) [a] for a single-layered, single-sided disc and 8.5 GB (7.92 GiB) for a dual-layered, single-sided disc. [23] The DVD specification ended up similar to Toshiba and Matsushita's Super Density Disc, except for the dual-layer option.
To record digital video, DVD-Video uses either H.262/MPEG-2 Part 2 compression at up to 9.8 Mbit/s (9,800 kbit/s) or MPEG-1 Part 2 compression at up to 1.856 Mbit/s (1,856 kbit/s). DVD-Video supports video with a bit depth of 8 bits per color, encoded as YCbCr with 4:2:0 chroma subsampling .
