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 to about 5 Gbit/s and storage capabilities beyond 2 TiB. 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 CFA announced the successor ... [...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, such as digital cameras as well as in many early games consoles such as the Neo Geo. They allow adding memory to such devices using a card in a socket instead of protruding USB flash drives. Common types of flash memory card include SD cards (including microSD), Sony's Memory Stick and CompactFlash. , SD cards are the most common type of memory cards. 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. The development of memory cards was driven in the 1980s by the need for an alternative to floppy disk drives that had lower power consumption, had less weight and occupied less volume in laptops. Some were also marketed as a lower cost alternative to ROM cartridges. Several competing and inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NVMe
NVM Express (NVMe) or Non-Volatile Memory Host Controller Interface Specification (NVMHCIS) is an open, logical-device interface specification for accessing a computer's non-volatile storage media usually attached via the PCI Express bus. The initial ''NVM'' stands for '' non-volatile memory'', which is often NAND flash memory that comes in several physical form factors, including solid-state drives (SSDs), PCIe add-in cards, and M.2 cards, the successor to mSATA cards. NVM Express, as a logical-device interface, has been designed to capitalize on the low latency and internal parallelism of solid-state storage devices. Architecturally, the logic for NVMe is physically stored within and executed by the NVMe controller chip that is physically co-located with the storage media, usually an SSD. Version changes for NVMe, e.g., 1.3 to 1.4, are incorporated within the storage media, and do not affect PCIe-compatible components such as motherboards and CPUs. By its design, NVM Expre ...

Mirrorless Interchangeable-lens Camera
A mirrorless camera (sometimes referred to as a mirrorless interchangeable-lens camera (MILC) or digital single-lens mirrorless (DSLM)) is a digital camera which, in contrast to DSLRs, does not use a mirror in order to ensure that the image presented to the photographer through the viewfinder is identical to that taken by the camera. They have come to replace DSLRs, which have historically dominated interchangeable lens cameras. Other terms include electronic viewfinder interchangeable lens (EVIL) and compact system camera (CSC). When compared to similar DSLRs, these cameras can be smaller, lighter, and quieter. In cameras with mirrors, light from the lens is directed to either the image sensor or the viewfinder. This is done using a mechanical movable mirror which sits behind the lens. By contrast, in a mirrorless camera, the lens always shines light onto the image sensor, and what the camera sees is displayed on a screen for the photographer. Some mirrorless cameras also ...

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) with a 16:9 aspect ratio is the dominant standard, whereas the digital cinema, movie projection industry uses 40962160 (Digital Cinema Initiatives, DCI 4K). The 4K television market share increased as prices fell dramatically throughout 2013 and 2014. 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" (''cf.'' "1080p"). 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 3 ...

Broadcast Quality
Broadcast quality is a term to denote the quality achieved by professional video cameras and time base correctors (TBC) used for broadcast television, usually in standard definition. 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 Design ...
