1. A method comprising:
- transmitting a complete set of digital content to each of a plurality of content reception systems substantially simultaneously;
receiving feedback from a content reception system indicating that the content reception system received an incomplete set of digital content and indicating particular missing content;
determining content to re-transmit based on the feedback; and
transmitting the determined content.

Abstract
A digital content transmission and reception system that uses feedback and re-transmission 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 the re-transmits content based on the feedback.

5. A method comprising:
-
receiving an incomplete set of digital content from a content transmission system;
performing content reception verification to determine that there is a particular portion of missing content;
transmitting an indication that the set of content is an incomplete set including transmitting an indication of the particular portion of missing content;
receiving digital content that comprises at least some of the particular portion of missing content; and
combining the received digital content with the incomplete set of digital content. - View Dependent Claims (6, 7)

15. A content reception system comprising:
-
a data receiver to receive an incomplete set of digital content via a one way communication link having a bandwidth; and
a reception verification system to determine that the received set of digital content is an incomplete set by comparing received data indicating what a complete set would contain with the received incomplete set and to provide feedback that indicates the particular missing digital content that is needed to complete the set of digital content by a second communication link having a lower bandwidth.

18. A content transmission system comprising:
-
a transmitter to transmit a complete set of digital content via a one way communication link having a bandwidth; and
a re-transmission system to receive an indication of particular missing digital content that is needed to complete an incomplete set of digital content corresponding to a content reception system via a communication link having a lower bandwidth and to re-transmit content based on the indicated missing content.

-
23. A system comprising:
-
a content transmission system to transmit digital content to a plurality of content reception systems via a communication link;
a content reception system to receive at least some of the digital content via the communication link, to perform reception verification processing by determining if a portion of the content is missing, and to provide feedback indicating that the portion is missing.

-
27. A system comprising:
-
a content transmission system to transmit a complete set of content via a communication link;
a content reception system to receive a corresponding incomplete set of content via the communication link; and
feedback means to allow the content transmission system to indicate missing content to the content reception system.
