This chapter describes the utilities shipped with the Sun MediaCenter software.

Sun MediaCenter software offers a variety of means to transfer video ﬁles. See Section 2.4 “Content Loading” on page 2-5 for a discussion of the alternatives.

In this chapter and elsewhere in this document, a title refers to a piece of video content, such a movie. A title is stored on a Sun MediaCenter server as the set of ﬁles that make up a piece of content. The name of a title is but one attribute of a piece of content. When you specify a title name for ﬁle transfer or for removal, all attributes of that title are transferred or removed. See Section 6.2 “Video-File Attributes” on page 6-4 for a complete description of title attributes.

5.1Setting a Title Access Control List

The Sun MediaCenter server software enables you to set an access control list (ACL) on a per-title basis. This type of ACL, along with server ACLs for titles and Content Manager sessions are described in Chapter 9 “Access Control Lists.”
