Abstract
A digital content transmission and reception system that uses feedback and retransmission of missing content is described. A content transmission system broadcasts a complete set of digital content to a plurality of content reception systems via a communication link. A content reception system receives a corresponding incomplete set of digital content, determines particular content portions that are missing, and provided feedback indicating the missing content portions to the content distribution system. The content distribution system then re-transmits content based on the feedback.
