In S-MAC the luminance is compressed by 2:1 and the two chrominance signals by 4:1 so that all three may occupy the same line. S-MAC's vision bandwidth is 11 MHz, only ~2.8x that of NTSC's vision bandwidth of 4.2 MHz. S-MAC can be carried on a single circuit and converted losslessly to and from C-MAC at any stage.
Among the family of MAC or Multiplexed Analogue Components systems for television broadcasting, D-MAC is a reduced bandwidth variant designed for transmission down cable. [1] The data is duobinary coded with a data burst rate of 20.25 Mbit/s so that 0° as well as ±90° phasors are used. D-MAC has a bandwidth of 8.4 MHz versus 27 MHz for C-MAC.
The Blue Print: Us vs. Them is the debut studio album by British hip hop duo D-Block Europe, self-released on October 9, 2020. It features guest appearances from Aitch, Lil Pino, Raye, Srno and Stefflon Don. [4] The album debuted at number 2 on the UK Albums Chart and number 1 on the UK R&B Albums Chart.
Originally E-MAC was designed for 15:9 pictures, it later adopted the 16:9 aspect ratio. In E-MAC all the 4:3 information is transmitted exactly as in C-MAC so that C-MAC receivers are still compatible. E-MAC hides extra luminance and chrominance information in the field blanking interval and parts of the line blanking interval.
D2-Mac processing on a Philips satellite receiver from 1990. D2-MAC is a satellite television transmission standard, a member of Multiplexed Analogue Components family. [1] [2] It was created to solve D-MAC's bandwidth usage by further reducing it, allowing usage of the system on cable and satellite broadcast.
One-key MAC (OMAC) is a family of message authentication codes constructed from a block cipher much like the CBC-MAC algorithm. It may be used to provide assurance of the authenticity and, hence, the integrity of data. Two versions are defined: The original OMAC of February 2003, which is seldom used. [1] The preferred name is now "OMAC2". [2]
The PowerPC 970 ("G5") was the first 64-bit Mac processor. The PowerPC 970MP was the first dual-core Mac processor and the first to be found in a quad-core configuration. It was also the first Mac processor with partitioning and virtualization capabilities. Apple only used three variants of the G5, and soon moved entirely onto Intel architecture.
The d-block contraction (sometimes called scandide contraction [1]) is a term used in chemistry to describe the effect of having full d orbitals on the period 4 elements. The elements in question are gallium , germanium , arsenic , selenium , bromine , and krypton [ citation needed ] .
