Sony Anycast Wikipedia
The Sony Anycast is a portable video switcher that runs a firmware version of the Linux OS. It provides 6 video inputs of varying sources (SD, HD via DV, S-video, or composite inputs.) It also provides RealMedia based streaming output.
The Anycast can record TX (also referred to as 'PGM') and isolated feeds to hard disk if required. One of the known hard-disks to work with the Anycast is the Maxtor One-Touch III (350gb & 500gb).
