Described are computer-based methods and apparatuses, including computer program products, for efficiently storing transport streams. A first sequence of one or more packets associated with the first transport stream is received, the first sequence comprising one or more data packets. A storage packet is generated by selecting one or more packets from the first sequence, the storage packet comprising a packet header and the one or more data packets. One or more null packet insertion locations are identified in a second sequence of one or more packets associated with a second transport stream. Null packet insertion information is generated based on the one or more null packet insertion locations, the information including data indicative of a reconstruction parameter related to reconstructing the second sequence from the storage packet by inserting one or more null packets that are not stored in the storage packet, wherein the packet header includes the null packet insertion information. The storage packet is stored.
