Abstract: A method of transforming a data file, the method executed by a processor. The method includes segmenting the data file into data segments and creating a bit index for each data segment having a size that is based on a configurable or preset data group unit. The method then involves indexing each data segment into its corresponding bit index by reading all data group unit values within the data segment and updating the bit index based on the read values, and generating an output data file or files comprising the bit indexes that represent the original data file.

Abstract: A method of receiving data segments of a data file on a user electronic device from a remote data source or sources over a data network. The data file being requested by or being pushed to an intended recipient application program executing on the user electronic device. The method includes receiving incoming data segments from the remote device over the data network and maintaining a memory buffer in memory of the user electronic device comprising one or more memory blocks. A status indicator for each memory block in the memory buffer is maintained that is indicative of the status of the memory block and the incoming data segments are allocated to specific memory blocks for storage in the memory buffer based at least partly on their respective status indicator. The stored data segments from the memory buffer are then provided to the recipient application program on the user electronic device for use or playback for example.
