Managing Content Types
The default content types supported by the Content Delivery Server are MIDlets,
ring tones, and images. You can define additional content types as needed. Each
content type must be associated with one or more MIME types.
MIME types specify the format of the content and enable information to be
exchanged between applications. The Content Delivery Server provides support for
a default set of common MIME types, each of which is associated with one of the
default content types. You can modify or delete these MIME types, register
additional MIME types, or associate the MIME type to a different content type as
needed.
In addition, each content type needs to be associated with digital rights management
(DRM). The following section discusses the DRM options supported in the Content
Delivery Server and their association with content types.
Content Submissions
The Catalog Manager administrator configures the Content Delivery Server to setup
either separate or single content type submission. By default, the Content Delivery
Server is configured for separate content type submissions. The two setups are
described as follows:
■ Separate content types - Each format of a content item is submitted individually.
Submitting content on a per format basis has the following benefits:
■ Individual formats of content can be submitted and managed individually
■ Defining the metadata and the pricing of content per format (for example, a
higher resolution image can be priced higher while a lower resolution image
can be priced lower)
■
Providing subscribers with the ability to choose from among compatible
content formats
For example, a content provider submits a screen saver image, Sunset, of content
type image and makes a separate submission of Sunset that has that content type
sms
_picture. Each format of Sunset has its own metadata and price.
■ Single content types - Content is submitted under one content type. Once the
initial content is submitted, edition can be submitted for each format of the
content. Editions have the same pricing option and preview file, if any, as the
original content. Submitting content on a per content type basis has the following
benefits:
