XQD Card
The XQD card is a memory card format primarily developed for flash memory cards. It uses PCI Express as a data transfer interface. The format is targeted at high-definition camcorders and high-resolution digital cameras. It offers target read and write speeds from 1 Gbit/s (0.125 GB/s) to about 4 Gbit/s (0.5 GB/s) and storage capabilities beyond 2 TB. The cards are not backward compatible with CompactFlash or CFast cards, and despite the name similarity, has no connection with the xD-Picture Card. XQD and CFast were both designed as a replacement of the 1994 CompactFlash standard. The format was first announced in November 2010 by SanDisk, Sony and Nikon, and was immediately picked up by the CompactFlash Association for development. The final specification was announced in December 2011. XQD version 2.0 was announced in June 2012, featuring support for PCI Express 3.0 with transfer rates up to 8 Gbit/s (1 GB/s). On 7 September 2016 the CF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Memory Card
A memory card is an electronic data storage device used for storing digital information, typically using flash memory. These are commonly used in digital portable electronic devices. They allow adding memory to such devices using a card in a socket instead of a protruding USB flash drives. History The basis for memory card technology is flash memory. It was invented by Fujio Masuoka at Toshiba in 1980 and commercialized by Toshiba in 1987. PC Cards (PCMCIA) were the first commercial memory card formats (type I cards) to come out, but are now mainly used in industrial applications and to connect I/O devices such as modems. In 1992, SanDisk introduced FlashDisk, a PCMCIA card and one of the first memory cards that did not require battery power to retain its contents. Since 1994, a number of memory card formats smaller than the PC Card arrived. The first one was CompactFlash and later SmartMedia and Miniature Card. The desire for smaller cards for cell-phones, PDAs, and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lexar
Lexar Media, Inc. is a Chinese brand of flash memory products manufactured by the Chinese company Longsys. The Lexar "JumpDrive" trademark was often used synonymously with the term USB flash drives when the technology was first adopted. History Early years (1996-2006) Lexar was founded as an American manufacturer of digital media products based in San Jose, California. Products manufactured by Lexar include SD cards, CompactFlash cards, USB flash drives, card readers and solid-state drives. Once a division of Cirrus Logic, Lexar leveraged its parent company's experience in building ATA controllers in developing its own flash controllers. Lexar was spun off from Cirrus Logic in 1996. Lexar was created by Petro Estakhri and Mike Assar. In 2005, Lexar was awarded $380 million in a lawsuit against Toshiba who copied Lexar's flash memory technology.

Mirrorless Interchangeable-lens Camera
A mirrorless camera is a photo camera featuring a single, removable lens and a digital display. The camera does not have a reflex mirror or optical viewfinder like a digital single-lens reflex (DSLR) camera, but may have an electronic viewfinder. Many mirrorless cameras retain a mechanical shutter. Like a DSLR, a mirrorless camera accepts any of a series of interchangeable lenses compatible with its lens mount. Terminology Mirrorless cameras are sometimes referred to as mirrorless interchangeable-lens cameras (MILC), or digital single-lens mirrorless (DSLM) cameras. This latter name highlights their connection to DSLRs. Other terms include electronic viewfinder interchangeable lens (EVIL) cameras and compact system cameras (CSCs). Overview Mirrorless cameras are mechanically simpler than DSLR cameras, and are smaller, lighter, and quieter due to the elimination of the moving mirror. While nearly all mirrorless cameras have a mechanical shutter, many also have an elec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4K Resolution
4K resolution refers to a horizontal display resolution of approximately 4,000 pixels. Digital television and digital cinematography commonly use several different 4K resolutions. In television and consumer media, 38402160 (4K UHD) is the dominant 4K standard, whereas the movie projection industry uses 40962160 (DCI 4K). The 4K television market share increased as prices fell dramatically during 2014 and 2015. 4K standards and terminology The term "4K" is generic and refers to any resolution with a horizontal pixel count of approximately 4,000. Several different 4K resolutions have been standardized by various organizations. The terms "4K" and "Ultra HD" are used more widely in marketing than "2160p". While typically referring to motion pictures, some digital camera vendors have used the term "4K photo" for still photographs, making it appear like an especially high resolution even though 3840×2160 pixels equal approximately 8.3 megapixels, which is not considered to be ...

As the standards for commercial television broadcasts have changed from analog television using analog video to digital television using digital video, the term has generally fallen out of use.Broadcast Engineering - Broadcast quality /ref> Manufacturers have used it to describe both and " |
XDCAM EX
XDCAM is a series of products for digital recording using random access solid-state memory media, introduced by Sony in 2003. Four different product lines the XDCAM SD, XDCAM HD, XDCAM EX and XDCAM HD422 differ in types of encoder used, frame size, container type and in recording media. None of the later products have made earlier product lines obsolete. Sony maintains that different formats within XDCAM family have been designed to meet different applications and budget constraints. The XDCAM range includes cameras and decks which act as drop-in replacements for traditional VTRs allowing XDCAM discs to be used within a traditional videotape-based workflow. These decks can also serve as random access computer hard drives for easy import of the video data files into non-linear editing systems (NLE) via FireWire ( IEEE 1394) and Ethernet. In September 2008, JVC announced its alliance with Sony to support the XDCAM EX format. In August 2009, Convergent Desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
