Open Host Controller Interface (OHCI) [1] is an open standard.. Die shot of a VIA VT6307 Integrated Host Controller used for IEEE 1394A communication. When applied to an IEEE 1394 (also known as FireWire; i.LINK or Lynx) card, OHCI means that the card supports a standard interface to the PC and can be used by the OHCI IEEE 1394 drivers that come with all modern operating systems.
IEEE 1394 is a serial bus architecture for high-speed data transfer, serial meaning that information is transferred one bit at a time. Parallel buses utilize a number of different physical connections, and as such are usually more costly and typically heavier. [6] IEEE 1394 fully supports both isochronous and asynchronous applications.
FireWire is Apple Computer's trademark for the IEEE 1394 standard. FireWire cameras are available in the form of photo cameras and video cameras , which provide image and audio data . A special form of video cameras is used in the domains of industry, medicine , astronomy , microscopy and science .
IEEE 1394 was proposed by High-Definition Audio-Video Network Alliance (HANA Alliance) for all cabling needs, including video, over coaxial or 1394 cable as a combined data stream. However, this interface does not have enough throughput to handle uncompressed HD video, so it is unsuitable for applications such as video games and interactive ...
IEEE 1394 (branded "FireWire") is a digital data transfer protocol commonly used for digital cameras (common on MiniDV tape camcorders), but also used for computer data and audio data transfers. Unlike Point-to-Point connections listed above, IEEE 1394 is able to host several signals on the same wire, with the data delivered and shown on the ...
Hard disk drives are accessed over one of a number of bus types, including parallel ATA (PATA, also called IDE or EIDE; described before the introduction of SATA as ATA), Serial ATA (SATA), SCSI, Serial Attached SCSI (SAS), and Fibre Channel.
The selected Remote Terminal then sends a single 16-bit Status word. RT to Controller Transfer. The Bus Controller sends one transmit command word to a Remote Terminal. The Remote Terminal then sends a single Status word, immediately followed by 1 to 32 words. RT to RT Transfers. The Bus Controller sends out one receive command word immediately ...
The P&D connector shares the 30-pin plus quad-coax layout of EVC, which carries digital video, analog video, and data over Universal Serial Bus (USB) and IEEE 1394 (FireWire). At a minimum, the P&D connector is required to carry digital video, in which case the connector is designated P&D-D ; when both digital and analog video are included, the ...
