Patent abstract

A method of generating an aggregate frame having a header unit, which carries MAC-header information applicable to one or more data units of said aggregate frame. Since each data unit of the aggregate frame no longer needs to carry the full MAC-header information, the overhead associated with the MAC header can be significantly reduced. At the receiver, the full MAC header corresponding to the data unit is reconstructed by (i) matching the appropriate header and data units to one another and (ii) combining the information present in the header unit and the compressed header portion of the data unit. Embodiments of the present invention are capable of improving the data throughput, for example, in an entertainment network having paired source and destination devices (e.g., a DVD player and an LCD screen) with a relatively large amount of data streamed from the former to the latter.
