Abstract: A content distribution system receives data describing media content available from one or more vendors. The content distribution system generates data that describes an offer and associates the media content data with the offer. The content distribution system provides data describing an offer to a client device. The client device receives a request for a media content offer. The media content offer may include one or more instances of media content. Each instance of media content is available from a media vendor. For each media content instance associated with the offer, the client determines a vendor able to provide the media content, and submits a request for the media content to the vendor.

Abstract: In an implementation of broadcast content delivery, content is broadcast to television-based client devices via a broadcast communication link. The content can be generated for display to include a user-selectable control to initiate a request for additional content that includes broadcast content and/or on-demand content. A content provider receives the request for the on-demand content from a client device via a two-way communication link, and broadcasts the on-demand content to the television-based client devices via a channel of the broadcast communication link. The content provider also communicates an identifier via the two-way communication link to the client device such that the client device can identify the channel of the broadcast communication link and receive the on-demand content via the broadcast communication link.
