45 nanometer (45 nm) is the buzzword of choice (2007-2008) for an advanced semiconductor manufacturing process that Intel used for mass chip production, starting in late 2007. The 45 nanometer manufacturing process uses new materials, including hafnium-based high-k gate dielectrics and metal gates, to reduce electrical current leakage in transistors. Contrast with 90 nanometer.
480p equates to 480 lines of progressive video (480 lines per frame). 480p60 refers to 60 frames per second; 480p30 refers to 30 frames per second; and 480p24 refers to 24 frames per second (film source). Usually refers to 720×480 (or 704×480) resolution.
Short for fourth generation, 4G is an ITU specification that is currently being developed for broadband mobile capabilities. 4G technologies would enable IP-based voice, data and streaming multimedia at higher speeds and offer at least 100 Mbit/s with high mobility and up to 1GBit/s with low mobility (nomadic). 4G is an IP-based and packet-switched evolution […]
In digital video, video signals are encoded when recorded and decoded on playback. Depending on the digital format, the video signal will be sampled at either 4:1:1 or 4:2:2. See anamorphic widescreen.
