摘要： A method for facilitating multiple recordings via a single tuner includes isolating data packets 13 associated with recording candidate media assets from at least two broadcast data streams and generating at least one broadcast recording data stream from a subset of the isolated data packets. The broadcast recording data stream is broadcast in parallel with the original broadcast data streams, where the broadcast recording data stream is broadcast via a dedicated broadcast recording device 22D and the original broadcast data streams are broadcast via other broadcast devices 22A, 22B, 22C. The remaining data packets not included in the isolated data packets are stored in broadband data segments 16, and transmitted 17 via an IP connection 5 to facilitate reassembly of partially recorded media assets, where the partially recorded media assets were recorded from the broadcast recording stream. Related methods and apparatus are also disclosed. The number of programs included in a given transponders data stream can therefore be increased by broadcasting a certain ratio of each program as a segmented broadcast and delivering the left-over packets via broadband. The exact percentage of segments broadcast is variable and may be uniform, prioritised or subject to manual input.
