    摘要： A method for transmitting video streams from a server to a media device includes selecting by the server first encoding parameters for a first set of video streams based on a first current bandwidth capacity for a network and based on a first current window size of a receive buffer of the media device, and transmitting the first set of video streams from the server to the media device. The method includes selecting by the server second encoding parameters for a second set of video streams based on a second current bandwidth capacity for the network based on a second current window size of the buffer. The first current bandwidth capacity is different from the second current bandwidth capacity or the first window size is different from the second current window size. The method includes transmitting the second set of video streams from the server to the media device.
