Abstract
Content receivers may simultaneously record multiple instances of content for multiple programming channels based on content provider instructions. Systems and methods utilize the content receivers to record these multiple instances from at least a single transponder. In some instances, multiple transponders may have a common control word so that content carried on each such transponder may be simultaneously received, decoded and recorded. Further, a single demodulator may be associated with multiple tuners, so that the single demodulator processes all content received from transponders with common control words and/or other encryption mechanisms.
