Link adaptation based on video quality monitoring for H.264/AVC video transmission over WLANs
Link adaptation algorithms employed by wireless routers traditionally use retransmission to achieve high error-free data throughput. Such methods do not take into account the delay sensitive nature of video data. In this paper, we investigate the use of reduced-reference video quality monitoring...

| Summary: | Link adaptation algorithms employed by wireless
routers traditionally use retransmission to achieve high error-free
data throughput. Such methods do not take into account the delay
sensitive nature of video data. In this paper, we investigate the use
of reduced-reference video quality monitoring for video oriented
link adaptation. Estimation of the quality degradation due to
channel errors is performed at the receiver side using the NoReference
video quality Monitoring metric. The estimates are sent
to the encoder side where, combined with mean squared error
values for the encoded video, they form a reduced reference metric
that gives information about the quality of the video at the
receiver. Link adaptation is then performed using this reduced
reference metric. |
