Software Overview
The SGI Media Server software provides scalability and maximum flexibility. The
software includes the following:
• SGI Video Server Technology (VST), the core software of the SGI Media Server. VST
provides real-time, frame-accurate recording and playback of broadcast-quality
digital media.
• Control interface modules, which provide device-dependent code. For example,
there is a control interface module that contains the code that is specific to VDCP
controllers.
• Media device interface modules, which contain format-dependent code that
provides access to the ports over which media is played and recorded.
• Format interface modules, which provide handlers for accessing specific digital
media storage formats. For example, there are format interface modules for
MPEG-2, DVCPRO 25, DVCPRO 50, DVCAM, and DV (16-bit/48 Khz only)
compression.
Figure 1-2 shows the primary software components in VST. The remainder of this section
describes the software components shown in Figure 1-2.
