Communications systems with retransmission request budgets

摘要

A media communications system using a multicasting or broadcasting technique, where each individual sink is allowed to request retransmissions according to a budget. The media communications system maintains the media quality of sinks that have a good communications channel in situations where one or more of the sinks is experiencing a bad communications channel, and where otherwise the communications channel would be saturated with retransmission requests and retransmissions which would affect other and possibly all media sinks.
