Abstract: Arrangements and methods are provided that allow integration of connected online services within a high-definition interactive framework, and in particular within an advanced content interactivity layer. In this way, the online services may enjoy enhanced features on an advanced content media device. For example, content running on an advanced content media device may be configured to detect an online service's feature and may thus present the user with additional features that interact with the online service. An advanced content media device may detect another user's advanced content media device through a network, and in particular a media service on the network, allowing chat and synchronized playback of content. Advanced content media devices may vary, but may include, e.g., a multimedia player, a media center, a game console, a personal computer, and so on.

Abstract: An active content trust model provides security in a help system. The security is provided in response to a call from a calling application to access active content. When the call is received, a determination is made, based on predetermined criteria, which execution mode to use to access the active content. The active content is then accessed in the determined execution mode, thus providing the security.

Abstract: Arrangements are provided for dynamically attaching advertisements to requested and downloaded content items. The advertisements or other content are combined with the requested and downloaded content item so that future playback of the content item also includes playback of the advertisement. The attachment may be performed at the time that the content item is requested, or the advertisement may be retrieved over a network at the time the requested content item is played back. The content may also be local to the client, e.g., downloaded content or content from an HD-DVD, and the same may instigate the playing of a downloaded advertisement at the time of downloading, loading, or playback. In any case, the advertisement may be played back before, during or after the playback of the requested content item. The combining of the advertisement with the requested content item may occur at the server-side or at the client side.
