What is ISMV file?

An .ISMV file is an encoded multi-media smooth streaming format supported for a Microsoft IIS Web Server. The .ISMV file is saved in the Protected Interoperable File Format (PIFF) that is derived from the MPEG-4 specification. The ISMV file is fragmented into smaller parts and these parts can be streamed at different transfer rates associated with different quality video level. As the Microsoft IIS Web Server can host multiple ISMV files, the smooth streaming technology enables dynamic detection of the bandwidth rate and facilitates streaming of the ISMV files that best fits the bandwidth rate.
