ABSTRACT:
Program data for use in electronic program guides is fragmented in advance of delivery to a low resource client. In the described implementation, the program data is fragmented into equal size fragments. The size of each fragment is selected to guarantee that the data fragments will fit in pre-allocated memory segments at the client. When the program data is delivered to the client, the client stores the data packets in the memory segments without making system calls to the memory.
