The MSM’s primary interface is the MSM Client API, described in the Sun

MediaCenter Server Programmer’s Guide.

The MSM supports playthrough, trick play, and other features of the Media File System.

1.3.3Content Manager

The CM provides for the loading of content onto a Sun MediaCenter server. Server requirements for content, such as Table of Contents files and index files (for trick play) are handled transparently by the CM. The CM also supports the movement of content between Sun MediaCenter servers and between a server and a client. This capability provides for the backing up and restoring of video files.

The CM has a server-based set of RPCs and a SPARC client-based library, both described in the Sun MediaCenter Server Programmer’s Guide. Chapter 4 describes a Web-based tool for moving content onto a Sun MediaCenter server. Chapter 5 presents a set of utilities based on CM. Chapter 6 describes the Sun MediaCenter FTP daemon, which is also based on CM.

1.3.4Web-based Tools

The following Web-based tools are provided with the Sun MediaCenter server software:

The Configure utility allows you to configure a Sun MediaCenter server. This tool is described in the Sun MediaCenter Installation and Configuration Manual.

WebAdmin allows you to monitor server operations. This tool is described in Chapter 3.

CmTool allows you to transfer video content to a server. This tool is described in Chapter 4.

1.4Video Output Interfaces

Sun MediaCenter software is designed to output streams over ATM or Fast Ethernet, using SunATM™ or SunFastEthernet™, respectively. With both types of output, the streams are delivered at a constant bit rate; there is no dynamic flow control or error recovery protocol. This is referred to as the “push” model of stream delivery and is discussed in Section 1.7, “Push Model,” on page 1-11.
