Abstract
Official abstract text for this publication.
When controlling transmission channel parameters and video encoding parameters so as to be linked to each other in video transmission, the video quality on the receiving side is further improved. As a parameter control unit that controls video encoding parameters regarding video encoding in a video encoding unit and transmission channel parameters regarding error correction coding and modulation in a channel coding/modulation unit so as to be linked to each other, a cross layer rate control unit is provided. The cross layer rate control unit performs variable control of the GOP size according to propagation changes by reducing the GOP size when the predicted value of the PHY transmission rate is larger than a determined reference value and increasing the GOP size when the predicted value of the PHY transmission rate is equal to or less than the determined reference value.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wireless communication device comprising: a video encoding unit configured to perform video encoding on video data to generate an encoded video data; a channel coding and modulation unit configured to perform error correction coding and modulation on the encoded video data to generate channel coded video data; a signal transmission unit configured to transmit the channel coded video data; and a control unit configured to perform variable contro…
