Abstract:
1. A method of storing a video data stream on a hard disk drive (HDD) for efficient non-sequential access to the stored stream of video data, the HDD having a plurality of sectors, each sector having a first integer of user data bytes, the HDD addressable on sector boundaries for non-sequential access, the video data stream including a sequence of original transport packets, each original transport packet having a second integer of bytes, the second integer of bytes different from the first integer of user data bytes, wherein a third integer of original transport packets are storable in a fourth integer of sectors, the fourth integer being a minimum number of sectors with the same number of user data bytes as the number of bytes in the third integer of original transport packets, the method comprising: receiving the sequence of original transport packets; adding a fifth integer of bytes to each original transport packet to create a sequence of modified transport packets, each modified transport packet having a sixth integer of bytes; and storing the sequence of modified transport packets on the HDD, wherein a seventh integer of modified transport packets are stored in an eighth integer of sectors, the eighth integer being a minimum number of sectors with the same number of user data bytes as the number of bytes in the seventh integer of modified transport packets, the eighth integer of sectors smaller than the fourth integer of sectors.
