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:
