Abstract:
1. A method for managing transmission of data files to users, comprising: dividing a first file into a plurality of first segments; dividing a second file into a plurality of second segments, wherein the first and second files are different files; sending a select first segment from a data transmission manager to a first user device and a different first segment from the data transmission manager to a second user device; sending a select second segment from the data transmission manager to the first user device and a different second segment from the data transmission manager to the second user device; combining at least part of the select first segment or the select second segment sent to the first user device with at least part of the different first segment or the different second segment sent to the second user device to produce a combined segment which is of smaller size than the total size of the at least parts before combining; and transmitting the combined segment from the data transmission manager to the first user device and to the second user device; wherein the combined segment allows the first user device to recover the at least part of the different first segment or the different second segment sent to the second user device using the combined segment, the select first segment, and the select second segment sent to the first user device; wherein the combined segment allows the second user device to recover the at least part of the select first segment or the select second segment sent to the first user device using the combined segment, the different first segment, and the different second segment sent to the second user device.
