Media Types and Formats
The SGI Media Server supports two media types, intraframe and interframe media, and
several media formats: DIF, SGI MPEG-2, SMPTE 360M (playout only), and MXF.
Media Types
The SGI Media Server supports intraframe media. In intraframe media, the video data
for each frame is self-contained and does not depend on the data from neighboring
frames. The SGI Media Server supports MPEG-2 I-frame, DVCPRO 25, DVCPRO 50,
DVCAM, and DV (16-bit/48 Khz audio only) intraframe media. The MPEG-2 DVCPRO
25 and DVCPRO 50 formats may be contained within an MXF content file.
The SGI Media Server also supports interframe media using MPEG-2 long GOP. The
media type depends on the information content contained in neighboring frames of a
video sequence. The SGI Media Server video codec controls parameterize the interframe
compression.
Media Formats
The SGI Media Server uses several formats for storing digital media in its clip cache
filesystem(s): intraframe media in DIF format—for fixed-sized frames, including
DVCPRO 25, DVCPRO 50, DVCAM, and DV (16-bit/48 Khz audio only). Further,
MPEG-2 and IMX formats may be created under appropriate hardware and VST setup.
The SGI Media Server supports the following file formats:
