In third generation (3G) mobile communication systems, the demand for wireless P-MP (Point-to-MultiPoint) transmission,
which send a single video to multiple users, has been growing.
Authors proposed a spreading-code assignment algorithm for P-MP video transmission.
This algorithm classifies mobile stations receiving a video stream into two groups - high quality and low quality,
according to their channel quality,
and controls the transmission power and the transmission rate of each group independently.
Although this scheme can improve the throughput and video quality, it needs to transform a video stream to two streams.
In this paper, we apply scalable video coding to P-MP transmission and
propose a new algorithm.
The combination P-MP transmission and scalable video coding can improve video quality drastically. |
