Compression Formats
The MPEG-2, DVCPRO 25, DVCPRO 50, DVCAM, and DV (16-bit/48 Khz only)
compression algorithms can be used to provide a compressed video stream, which can
be stored in a file. This file format is useful for transporting video across data networks.
In addition to traditional TCP/IP data networks, this data can also be transmitted across
coaxial video networks as data to and from VTRs, nonlinear editors, and servers. The
following section explains how to display this compressed data stream during transfer.
Video I/O, Compression, and File Formats
The SGI Media Server uses Serial Digital Interface (SDI) protocols for primary video I/O
operations, which are SMPTE-259M compliant. Additionally, the server employs
composite analog video for Genlock input and output monitoring. The SGI Media Server
is configurable for either MPEG-2, DVCPRO 25, DVCPRO 50, DVCAM, or DV (16-bit/48
Khz only) compression types. For MPEG-2, you can select I-Frame, long GOP, and
optionally IMX/constant-byte GOP (CBG).
The supported file formats include the following:
File Format Standard
DIF DVCAM SMPTE-314M
DIF DVCPRO 25 SMPTE-314M
DIF DVCPRO 50 SMPTE-314M
GXF MPEG-2 I-frame—playout only SMPTE 360M
MXF D10/IMX SMPTE-356M
MXF OP-1a DVCPRO 25/50 SMPTE-378M
MXF OP-1a (MPEG-2) SMPTE-378M
SGI MPEG-2
See “Supported SMPTE Standards” on page 18 for a list of supported standards.
