Patent ID: 7684430

Claim:
A method, comprising: receiving by a MAC layer of a content server a transmission frame from an upper layer of the content server, the transmission frame being associated with a given access class of multiple access classes, the given access class being associated with a primary priority level, the transmission frame including content being associated with a secondary priority level; setting MAC layer parameter values based on the primary priority level, a given one of the MAC layer parameter values being based on the primary and secondary priority levels; and contending for access to a wireless medium using the MAC layer parameter values; wherein the given one of the MAC layer parameter values is one of a first parameter value relating to arbitration interframe space, a second parameter value relating to a maximum value of a contention window, a third parameter value relating to a minimum value of the contention window, and a fourth parameter value relating to a transmission opportunity; wherein the transmission frame from the upper layer includes a video AC frame having one of an intra-coded frame (I frame) fragment, a prediction coded frame (P frame) fragment, and a bi-directional frame (B frame) fragment; and wherein the MAC layer transfers the transmission frame to the wireless medium with higher priority if the transmission frame includes the I frame fragment or the P frame fragment than if the transmission frame includes the B frame fragment.
