Rose Electronics has launched a remote server and console access system, the Ultralink Phase II, that it claims solves the 'jerky mouse' problem.
Remote control of graphical user interfaces over bandwidth-limited links, especially those covering long distances, suffer from latency, caused by the volume of data traversing the slow link. This results in imprecise mouse control, which can mean misplaced mouse clicks, with potentially catastrophic results - as sysadmins in charge of remote servers will no doubt know to their cost.
Rose claims to have fixed the problem by reducing the volume of data that must traverse the link. Using frame comparison and phase detection algorithms, along with proprietary digital filtering, the company says that the mostly static image of a PC screen can be quickly conveyed by transmitting only changes, not the whole screen.
According to the company, using the Pentium's SSE and MMX parallel processing technology, its Ultralink matrix system provides frame comparison that's is "near real-time", providing "almost instantaneous" mouse response. The filtering removes smear and helps eliminate artefacts produced by cable degradation and latency.
The system costs €4,000.
