This guide provides an overview of the DMediaPro DM3 board. It describes how to connect the DMediaPro DM3 board to an SGI video breakout box (VBOB) for high-definition and standard-definition input/output (I/O). It also describes how to synchronize audio with video when using the DMediaPro DM3 board, and how to program the board using the OpenML media library software development kit ( ML) and device-specific controls.
The DMediaPro DM3 board transmits and receives uncompressed high-definition video and standard-definition video in real-time. The DMediaPro DM3 board can be installed and used with the SGI Onyx 350 dual-head graphics system and the Silicon Graphics Tezro visual (deskside and rackmountable) workstations. In the future, the DMediaPro DM3 board (referred to as the DM3 board throughout this guide) will also be compatible with other SGI systems.
This guide is provided for the sophisticated video user in a professional or research environment. You should be familiar with video standards, the operation of the applicable SGI system or workstation, and the ML-related information in the OpenML Media Library Software Development Kit Programmer's Guide.
Only a trained SGI support service engineer can install the DM3 board in an SGI Onyx 350 graphics system, and a rackmountable or deskside Silicon Graphics Tezro visual workstation.
![]() | Note: This option board requires IRIX 6.5.21 (with any required patches) or later. |
You control and program the board using ML. For a description of ML device-independent calls and controls, see the OpenML Media Library Software Development Kit Programmer's Guide (007-4504-00x).
The following topics are covered in this guide:
Chapter 1, “Features and Capabilities”, describes the main components of the DM3 board, and includes a general overview of product features.
Chapter 2, “Connecting the DMediaPro DM3 Board to VBOB”, shows you how to set up high-definition and standard-definition input/output (I/O) using the SGI video breakout box (VBOB).
Chapter 3, “Setting Up Audio Synchronization”, shows you how to synchronize audio with video when using the DM3 board in a typical studio configuration with a tape deck.
Chapter 4, “Programming the DMediaPro DM3 Board”, shows you how to use ML and device-specific controls to program the board.
The following publications contain additional information that may be helpful:
In addition to this guide, the OpenML Media Library Software Development Kit Programmer's Guide (007-4504-00x) and the SGI Video Breakout Box Owner's Guide (007-4243-00x), are shipped with the DM3 board. If you are using an SGI PCI Digital Audio Board, see the PCI Digital Audio Board Installation Guide (007-3502-00x).
It is also a good idea to have your system owner's guide available.
You can obtain SGI documentation, release notes, or man pages in the following ways:
See the SGI Technical Publications Library at http://docs.sgi.com . Various formats are available. This library contains the most recent and most comprehensive set of online books, release notes, man pages, and other information.
If it is installed on your SGI system, you can use InfoSearch, an online tool that provides a more limited set of online books, release notes, and man pages. With an IRIX system, select Help from the Toolchest, and then select InfoSearch. Or you can type infosearch on a command line.
You can also view release notes by typing either grelnotes or relnotes on a command line.
You can also view man pages by typing man <title> on a command line. For example, to display the man page for the Add_disk command, type the following on a command line:
man Add_disk |
References in the documentation to man pages include the name of the command and the section number in which the command is found. For example, “Add_disk(1)” refers to the Add_disk command and indicates that it is found in section 1 of the IRIX reference.
For additional information about displaying man pages using the man command, see man(1).
In addition, the apropos command locates man pages based on keywords. For example, to display a list of man pages that describe disks, type the following on a command line:
apropos disk |
For information about setting up and using apropos, see apropos(1) and makewhatis(1M).
