The Original LSM product was the HCT2 platform, a RAM based video recorder. Due to the price of RAM in those days (1990's), few could afford the luxury of capacities much higher than 3 minutes! Despite this limitation we proved that the product had it's uses: Slow-Motion during events, montages into commercial breaks, analysis and closing montages - all available instantly.
The HCT4 unit was the next to appear. This was EVS venturing into the unknown territory of hard disks! The early platforms had an audio capability utilising 2 sound cards. One was internal to the LSM mainframe and the other housed in a 19inch 1 U half depth frame. This occasionally worked, although lip sync was a major issue! The later generation of HCT4 systems had an external ADR (Audio Disk Recorder) and this was the first LSM product that one could confidently use. There were occasional "crashes" and lip sync errors, but with operator discipline, reliability was good. Concurrent with the launch of the HCT4 product, many other facilities and features were promised: networking, audio editing, enhanced effects, to name but a few, and these have materialised in subsequent releases of the EVS range!
The majority of EVS systems are now based upon the XT platform. This has benefited from many years experience gained by EVS developers and is now the industry standard in video disk recorders. To call the XT a slow-motion machine is an insult to the capability of the system. It is now a versatile server based solution for TV production.
The latest offering from EVS is the High Definition XT 2 successor to the Standard Definition range. Editec have a large stock of both ranges of XT EVS systems in order to fulfill Client needs in both definitions.
Let's go through the current capabilities of LSM XT, and you will probably be able to answer your own questions!
