US Patent 7835397 Frame processing

A technique is disclosed for generating a plurality of output frames based on a single input frame. An input interface is configured to receive at least a portion of the input frame. An output controller is configured to receive, for each of the plurality of output frames, a new header, and combine each new header with at least a portion of the input frame. An output frame may be generated for which no corresponding input frame exists. An input interface is configured to receive an indication that the output frame should be generated. An output controller is configured to receive a generated header and combine the generated header with a dummy payload to form the output frame.
