Bahram,
RaveHD offers the storage, the way to ingest uncompressed and even the means to compress down to MPEG (along with many other formats). Sits on the network and can be accessed by other systems and applications, they just see it as one big drive.
Of course there is a whole bunch more to RaveHD but it is possible to go from tape to Compressed format, in one sweep and all automated.
Need multiple compressed formats simultaneously?
Need downconverted HD to SD and compressed simultaneously?
