Basics of the Fibre Channel Standard

by Karl Paulsen, 12.05.2007

The standard of choice for many of the high-performance video media storage platforms is the Fibre Channel (FC), which is more than just switching or a type disk drive interface. FC is a vast set of applications with a depth not unlike those of SCSI, SATA (serial ATA), and other storage device and network technologies. more

Coding for Magnetic Storage Mediums

The Essence of Wrappers And Components

by Karl Paulsen, 5.02.2007

The material interchange of moving media can be accomplished by different means. A tape or disc may be used as a physical transport, with its content comprised of essence in the form of a compressed file, a contiguous interleaved video sequence (i.e., a videotape), or a string of individual files (i.e., JPEG images) that when ordered properly for reproduction, make up a video clip. more
