Patent ID: 7515604

Claim:
A transmitter transmitting content data over a network using Transmission Control Protocol/Internet Protocol (TCP/IP), the transmitter comprising: an arithmetic circuit configured to perform TCP/IP processing on first packet data and to generate first header data associated with said first packet data; a hardware processor circuit configured to generate from content data said first packet data for processing by said arithmetic circuit, and to split the TCP/IP processed first packet data so as to generate a plurality of second packet data and to generate a plurality of second packet TCP headers based on the first header data generated by said arithmetic circuit, and to attach respective ones of the second packet TCP headers to respective ones of the second packet data, the hardware processor circuit performing at least a checksum calculation, the checksum being a field contained in a second packet TCP header attached to a respective second packet data and; an interface configured to supply to said arithmetic circuit said first packet data from said hardware processor circuit for TCP/IP processing, and to supply to said hardware processor circuit the TCP/IP processed first packet data; wherein said first packet data is of a size greater than said second packet data.
