Summary: | Transmission loss is the major killer to quality delivery of video streaming, in particular in error-prone environments such as wireless channels. Moreover, indefinite packet delay/jitter can also induce effective loss of received packets at the receiver end due to real-time requirements by the play-out buffer. To address the real-time issue, we propose a novel cross-layer design called PN_DVFI+DPM, where a frame-by-frame based video-importance classification scheme called P-normalized dispersive video frame importance (PN_DVFI) is adopted in the Application layer, and a corresponding dispersive piecewise mapping (DPM) algorithm for video packets among access category (AC) queues of different channel access resources is proposed in the MAC layer. The simulation results with a real-time cut at 400 ms show the superiority of our proposed PN_DVFI+DPM design over the existing ones, including EDCA, I/P+EAM and EPL+SPM. |
