摘要： A method for improved presentation of media information for wireless communication is described herein. Media services and program packages are ranked and ranking information is delivered to a mobile device along with the media information. The ranking information is then used by the mobile device to arrange the media services in a ranked order. The ranking information can also be used to assign a default service that is displayed whenever the mobile device is activated or whenever a selection is made to view media content. The ranking information can also be used to arrange program packages in a ranked order for subscription purposes.

摘要： Embodiments relate to systems and methods for delivering auxiliary data to a wireless or other device. Content, such as audio, video or textual content, can be hosted by a server for delivery to the device. The content can have associated resources, for example icons, barkers, intros, and outros that are associated with television programming or other media content. A metadata document can describe the set of resources or other auxiliary data associated with a service, channel or content by indicating a resource descriptor, and a URL or other associated resource locator information. The metadata document can be encoded in XML or other formats. The device can locate resources that are intended to be delivered with selected content, since links to the resources are integrated in the metadata document. From the resource descriptor, the device can also identify how a particular resource should be utilized for the service, channel or content.
