摘要： A system and method for dynamically encoding multimedia streams is provided. A user-end device is allowed to generate a network status message and transmit it to a data server, and the data server dynamically adjusts encoding parameters based on the network status message, encodes multimedia data using the adjusted encoding parameters, and sends the encoded multimedia data to the user-end device. This system and method solves problems where the picture quality and playback smoothness are affected by packets loss or error at the user end due to inability to adapt to constantly changing network conditions as in the prior art.

First, downlink channel state information is obtained at the receiver side. A set of indices of precoding matrices or a set of precoding matrices within the finite codebook are determined according to the obtained downlink channel state information at the receiver side. The selected indices of precoding matrices and a set of scalar coefficients are transmitted from the receiver to the transmitter. Thereafter, a refined precoding matrix is generated based on the set of indices of precoding matrices and the one or more scalar coefficients at the transmitter side. The refined precoding matrix is applied for transmission between the transmitter and the receiver.
