Abstract: Improved podcasts and techniques that facilitate their use are disclosed. The improved techniques can pertain to creating, publishing, hosting, accessing, subscribing, managing, transferring, and/or playing podcasts. According to one aspect, a client application can subscribe to podcasts and then automatically monitor the podcasts for updates to be downloaded. In the event that user interest in a podcast becomes inadequate, downloading of further updates can be restricted. According to another aspect, a podcast can be subscribed to through use of a portable subscription file. According to still another aspect, podcast feeds can be enhanced to include segment elements and other metadata.

Abstract: Some embodiments of the invention provide a method for distributing content over a network. The method distributes a single media storage structure to a device (e.g., a computer, portable player, etc.) that connects to the network. The media storage structure includes first and second pieces of encrypted content. Based on whether the device is allowed to access the first piece of content, the second piece of content, or both, the method provides the device with a set of keys for decrypting the pieces of the content that the device is able to access. The provided set of keys might include one or more keys for decrypting only one of the two encrypted pieces of content. Alternatively, it might include one or more keys for decrypting both encrypted pieces of content. For instance, the selected set of keys might include a first key for decrypting the first encrypted piece and a second key for decrypting the second encrypted piece. Based on the provided set of keys, the device can then decrypt and access either one of the two pieces of content in the media storage structure or both pieces of encrypted content in the media storage structure.
