Your distribution server will not only require quickly processors, but rapidly disk, much too, to tug the video as swiftly as is possible. SCSI and SATA (Serial ATA) by itself won't include several video streams, so You'll need a RAID of SCSI or SATA drives to thrust various hundred megabits for every next. And depending on the variety of streams supported, you might need Gigabit Ethernet or a number of Gigabit Ethernet interfaces.
